IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION TWO

THE PEOPLE,
Plaintiff and Respondent,
A163959
v.
MICHAEL DANIEL MARTIN, (Napa County
Super. Ct. No. 19CR003514)
Defendant and Appellant.

A jury convicted defendant Michael Daniel Martin of attempted murder
and four other crimes, and found true various enhancements. The trial court
sentenced him to an indeterminate term of 14 years to life in prison, plus a
determinate term of 13 years and 4 months in prison. On appeal, defendant
raises a number of evidentiary and instructional challenges. He also argues,
and the People agree, his sentence must be vacated in light of ameliorative
changes on two different sentencing schemes applicable to his case. We
affirm defendant’s convictions, but vacate his sentence and remand the
matter to allow the trial court to resentence him under current sentencing
laws.
BACKGROUND
The charges against defendant arose from allegations that on the
evening of December 11, 2019, he drove his then wife, Heather Robinson, to a

1
remote location up in the hills in the City of Napa, punched and strangled her
while inside the vehicle, and then struck her with the vehicle as she tried to
escape, causing her to fall down a ravine and sustain serious injuries.
Defendant’s defense at trial was that Robinson drove herself over the ravine,
and that he was not near the accident site at the time.
The Evidence
The Prosecution Case
Heather Robinson
In early 2015, Robinson began a relationship with defendant, then a
patient at a drug and alcohol treatment facility where Robinson was working.
Some time that year, defendant moved in with Robinson in her apartment in
Napa.
On October 4, 2015, Robinson, a former addict who had been sober for
about two decades, relapsed with alcohol. Realizing she was drunk, Robinson
went into her bathroom. Defendant came in and “lined up some meth.”
Upset by this, Robinson hit the mirror and knocked the methamphetamine
away. Defendant then hit Robinson and put his hand over her throat so that
she could not breathe. Robinson repeated to defendant, “[Y]ou’re killing me.”
She then passed out. When Robinson woke up, she looked in the mirror and
saw she had bruises all over her face and a black eye, and one of her eyes was
shut closed.
Robinson told her boss she had relapsed and quit her job. She did not
report the incident to the police.
After a few weeks had passed, Robinson stayed at her sister’s house for
a couple of days. After that she stayed at a homeless shelter for victims of
domestic violence for another several days. Robinson did not leave the
relationship with defendant, despite being told by others to do so, because she

2
“loved him so much.”
At some point in 2015, defendant was convicted of robbery, and
between 2015 and 2019, he was imprisoned. Robinson visited defendant
while he was in custody, and the two got married in 2015. Robinson found a
job working for an agency that helped find housing for homeless people.
In late October 2019, defendant was released from prison. On October
31, Robinson learned from defendant’s sister that defendant had relapsed. At
2:30 a.m. on November 1, defendant showed up drunk at Robinson’s
apartment. Terrified that he would get violent, Robinson asked defendant to
leave but he refused. Defendant also did not allow Robinson to leave.
Robinson then called defendant’s parole officer and told him that defendant
had been drinking and that she was scared. Upset that Robinson had called
his parole officer, defendant told Robinson that “people end up in ditches,”
“he was not going back to prison,” and “he knew how to get rid of people.”
When defendant’s parole officer showed up at Robinson’s apartment,
she told him that she wanted defendant to stay because he had told her he
would stop drinking. The parole officer left.
On another occasion in November, Robinson overheard defendant
talking to “some other girl on the phone.” Robinson got upset, started cursing
and yelling at defendant, and took the phone from defendant’s hand and
yelled, “I’m his fucking wife.” Robinson then picked up her phone and said,
“[F]uck you. I’m calling your PO.”
Defendant then followed Robinson outside, grabbed her phone, threw it
on the ground, and stomped on it. He told Robinson to “get in the fucking
house.” When Robinson had her hand on a gate to open it, defendant grabbed
her arm and tried pulling her back into the apartment. Robinson broke free
and ran down the street shouting for help. Some people nearby walked her

3
back to the apartment. Robinson drove away in her car and called the police
on her work phone.
When a police officer arrived at Robinson’s apartment, she told him
defendant was drunk, he had stomped on her phone, and she wanted him out
of her home. The officer asked her if defendant had harmed her, but she
replied that he had not. Robinson’s arm hurt, and she was unable to move it.
When she went to work the next day, she told her coworkers what
happened and that she was afraid of defendant. She also said to them, “[I]f I
ever came up missing that they needed to find me because he had killed me.”
Following these incidents, defendant repeatedly told Robinson,
“[Y]ou’re done. You’re done. People that snitch you’re done. I know how to
get rid of bodies. You know I’m not going back to prison.” Robinson packed
her car and stayed with her friend Heidi for four days.
When Robinson returned home from her friend’s home, she learned
from defendant’s mother and parole officer that defendant was staying at his
mother’s house. Defendant’s mother showed up with defendant at Robinson’s
apartment upset, and eventually Robinson allowed him to stay at her
apartment with the understanding that he would leave in a couple of days.
As of November 28, defendant and Robinson had made up and were living
together again.
In the weeks that followed, defendant continued to drink alcohol and
yell threats at Robinson. He also would not let Robinson go inside her room
and shut her door; he would open the door and asked her who she was talking
to and wanted to look at her phone. Defendant told Robinson, “I’m not gonna
let you lay in here and call the cops.” Defendant “was just constantly coming
in the room and standing over [her].”
Their neighbors often heard the two of them fighting, shouted at them

4
to be quiet, and called the police several times. Robinson did not report to
police that defendant was threatening her because she believed he would
change.
On December 10, defendant and Robinson got into an argument while
they were looking up their credit reports. Defendant accused Robinson of
buying a house with someone else. He also said that he had heard from
others that Robinson was having an affair with one of her clients at the
agency she worked at. Eventually, they stopped arguing, and defendant let
Robinson go to bed.
On December 11, Robinson went to work and when she arrived home
that afternoon, all of the blackout curtains in the living room were closed.
Defendant came from behind the door and told her he wanted all her phones,
credit cards, computers, passwords, and “access to everything.” Afraid,
Robinson complied.
That evening, defendant asked Robinson for money to buy cigarettes
and for her car to go to the store. They started arguing. Robinson then said
he could take the car, but she would come with him. They got into Robinson’s
car. Defendant pushed the seat all the way back to accommodate his 6’3”
height. When defendant did not make the turn to go to the corner store,
Robinson became terrified.
Defendant drove them through Downtown Napa until he reached a
dead end near a church. He flipped the car around and shut it off. He asked
Robinson how to turn off the car lights, which turned on when he shut the car
off. Robinson took the key fob from him to turn off the lights and put it in her
pocket. He then asked for the key fob back, but Robinson refused to hand it
over. Defendant started smoking marijuana and once he finished, he asked
Robinson for cigarettes. Robinson refused.

5
 Defendant started driving again, telling Robinson, “I know the truth.
You need to get honest with me. You need to tell me the truth. You don’t
have to lie to me.” If she did not tell him the truth, defendant said, “[you’re]
done. . . . [T]hat’s it. I’ve given you enough chances . . . . You’re done. You’re
done.” Robinson understood this to mean she was going to die. It was
raining, and defendant was driving erratically. Robinson closed her eyes and
prayed.
At some point later, defendant started driving uphill on a road.
Eventually he stopped the car and repeated to Robinson, “Tell me the truth.
This is your last chance.” Robinson started smiling, thinking to herself, “how
insane . . . that this is happening.” Defendant responded, “[A]re you laughing
at me?” before grabbing Robinson by the hair, punching her twice in the face,
and choking her. Robinson told him, “Michael, you’re killing me.”
Robinson managed to unbuckle her seatbelt, open the car door, and
walk outside toward the back of the car. Defendant got out of the car and
followed her. Robinson walked towards the front of the car. Just then, she
heard the car door shut and the car accelerate. Robinson felt the car strike
her right leg, and she fell down a hill. When Robinson looked up from where
she lay on the dirt, she saw defendant standing at the top of the hill, calling
her name. Robinson hid so defendant could not find her.
Robinson, lying in a bush and in pain, heard cars occasionally driving
by. At some point, she decided to go towards the cars. She used her one good
leg to push herself uphill through the mud and came upon her car stuck in
the hillside. Robinson crawled into the driver’s seat and tried to honk the
horn to sound, but could not because the air bag had deployed. She then
changed the car’s gear from neutral to park, put the passenger’s side seat into
a reclining position, crawled over it into the back seat, and put the seat back

6
up. Robinson wrapped herself in a blanket and robe that were in the car and
rested for the evening.
The next morning, Robinson heard someone up from the hill yelling.
Robinson screamed, “Help me,” and a man approached her and tried to call
for help on his phone. He eventually handed her the phone, and Robinson
explained that she was in a ditch. A woman then approached Robinson with
a blanket and water. Soon after, she heard medical personnel arrive and was
transported to a hospital. At the hospital, Robinson spoke to a detective and
told him that her husband was responsible for what had happened to her.
Robinson had to undergo surgery on her leg and arm, and was
bedridden for about a week. She was released in a wheelchair.
In February 2020, Robinson filed for divorce.
Other Percipient Witnesses
Robinson’s next-door neighbor, Jyl Glover, testified that Robinson was
a positive and upbeat person until a man had moved in with her. Glover
heard daily arguing “over and over . . . .” She specifically heard the man
swearing and yelling derogatory statements. Glover complained to the
landlord and the police about the noise.
Robinson’s coworker, Maricela Pelayo, testified that before November of
2019, Robinson was always happy and joking. Pelayo noticed an immediate
change in Robinson’s behavior when defendant was released from prison.
She started showing up late to work or leaving early, and her attitude was
more serious and less happy. Pelayo testified that sometime before
Thanksgiving of 2019, Robinson arrived to work with an arm sling. Pelayo
referred her to a domestic violence agency. Robinson told Pelayo that if she
did not show up to work one day, to look for her, because that would mean
something had happened or gone wrong. When Robinson did not show up to

7
work on the morning of December 12, 2019, Pelayo and other coworkers tried
to locate Robinson by calling a number of people, including defendant’s
mother and Robinson’s sister, and driving over to Robinson’s apartment.
Melissa Blonigen, another coworker of Robinson’s, also noticed a
change in Robinson’s mood and behavior after defendant returned home from
prison. Robinson became more introverted and would sometimes have quiet
conversations over the phone, after which she would be upset and leave.
Blonigen also testified that Robinson showed up to work in an arm sling one
day. And she recounted the day when Robinson did not arrive to work on
December 12, 2019, testifying that she and other coworkers tried to call
Robinson and other people to get information on her location.
Robinson’s friend Heidi Gigandet testified that in either fall or winter
of 2015, she saw Robinson had bruises all over her face and a black eye as if
she had been severely beaten. In November of 2019, Robinson stayed at
Gigandet’s house for several days. Robinson was emotionally distraught, and
she had complained about pain in her right arm. Robinson told Gigandet
that she had an argument with defendant, tried to leave her home, and
defendant physically stopped her by putting his hands on her and grabbing
her arm.
Defendant’s father, Dan Lilly, testified that defendant called him once
at around 10:10 p.m. on December 11, 2019, but the connection was bad and
the call was dropped. Immediately afterwards Lilly called defendant’s
mother, Deborah Martin, and told her he had just received a dropped phone
call from defendant. At approximately 10:35 p.m., while Lilly was on the
phone with Deborah1, he heard a loud knock on her door, followed by

1 To avoid confusion with defendant, we refer to Deborah Martin by her
first name.
8
defendant’s voice.
Deborah testified that defendant had called her around 10:05 p.m. or
10:10 p.m. on December 11, 2019. The connection also was poor and the call
dropped, so defendant called again on Deborah’s other phone. That call also
dropped, after which Deborah tried calling defendant but could not get
through. Deborah then spoke to Lilly over the phone. Approximately 35 to
40 minutes later, defendant showed up at Deborah’s house in wet clothes.
Defendant stayed overnight at Deborah’s house.
On December 12, 2019, defendant was arrested outside of Deborah’s
house.
Medical Personnel
On December 12, 2019, paramedic Daniel Gernetzke responded to the
scene and found Robinson in the back seat of her vehicle, which was down a
50- to 70-foot embankment. The large indentation in the earth that was a
significant distance away from the roadway, as well as the front end damage
to Robinson’s car, indicated that the car had accumulated enough speed to fly
off the roadway and launch “nose first into the earth.” Robinson told
Gernetzke that she had gotten into a fight with a man, who had strangled her
and pulled her hair out. Robinson said she was able to escape and jump out
of the vehicle, but was struck by her car, and then launched over the hillside
and into the bushes. Robinson appeared anxious, dirty, muddy, and
frightened. She had visible abrasions on her body, redness around her neck,
and limited mobility in her upper and lower extremities. She also
complained of pain to her throat. Due to the severity of her pain, Robinson
had to be lifted by the fire department in a roped rescue basket.
Dr. Michael Shifflett examined Robinson at the hospital on December
12, 2019, and found that Robinson suffered fractures to the bones in her

9
upper left arm and right lower leg, injuries that required surgery. Such
injuries were caused by “high energy trauma,” which may include, for
example, being involved in car accident. Robinson told Dr. Shifflett that she
had been assaulted by her husband, who then hit her with a car, causing her
to roll down an embankment. Dr. Shifflett testified that Robinson’s injuries
were consistent with her account of events. There was a low likelihood, Dr.
Shiflett explained, that Robinson’s injuries were caused due to her being in
the driver’s seat and getting into a collision, during which the airbags
deployed and the cabin of the vehicle remained intact.
Law Enforcement
On December 12, 2019, Sergeant David Quigley from the Napa County
Sheriff’s Department responded to the scene. He saw Robinson’s car facing
downhill 20 feet off the side of the road and 30 feet down the embankment.
Quigley saw “a lot of damage” on the driver’s side of the vehicle: the windows
and windshield were broken, and the airbag had been deployed. There also
were dents on top of the hood.
Also on December 12, 2019, Detective Joseph Perry responded to the
hospital where Robinson was admitted. Robinson, lying on the hospital bed,
had injuries to her face and body, including a black eye to her right eye. She
appeared to be in pain and looked “very disheveled.” Perry asked her what
happened. Robinson stated defendant had punched and strangled her inside
the vehicle, she got out of the car and ran, she was hit by the car, and she fell
down the ravine. Robinson also stated that defendant looked down at her
afterwards from the roadway. Robinson’s interview, which was recorded on
Perry’s body camera, was played for the jury.
Robinson also told Detective Perry that approximately two weeks
earlier, defendant had grabbed her arm and injured her. Perry observed red

10
markings on her neck and bruising around her right eye.
Jacqueline Shikowitz, an evidence technician for the Napa County
Sheriff’s Department, inspected and took photographs of Robinson’s damaged
car. Shikowitz testified that the driver’s “seat was pushed all the way back
away as far as it could be from the steering wheel,” consistent with the height
of a taller person.
Defendant’s former parole officer, Kamal Singh, testified about the
events in early November 2019. On November 1, 2019, Robinson contacted
Singh to report that defendant was under the influence of alcohol and drugs.
On November 4, Singh contacted defendant, and he admitted using alcohol.
When Singh visited Robinson’s home, she stated she wanted defendant
placed in an outpatient treatment program. Robinson called Singh on about
five other occasions, expressing her concerns about defendant’s treatment.
She never reported domestic violence.
On November 20, 2019, Officer Adam Barrera responded to Robinson’s
home when she called the police. Robinson stated that defendant had broken
her phone, but she did not report any violence.
Vehicle Evidence
Detective Alfred Speake, the People’s computer forensic expert,
testified that Robinson’s car was equipped with an infotainment system that
collected GPS data of the vehicle, as well as diagnostic trouble code (DTC)
logs, which identifies when a problem with the car arises. Speake
downloaded the data from Robinson’s car and gave it to Detective Perry.
The GPS data showed that at 9:06 p.m., Robinson’s car was located
near a highway and church on the valley floor in the City of Napa. At 9:22
p.m., the car traveled on Mount Veeder Road, a road that runs from the
valley floor and up the hills in Napa. At 9:56 p.m., the car was located near a

11
turnout area on Mount Veeder Road. And at 10:01 p.m., Robinson’s car
registered a catastrophic event.
Aaron Medina, a police sergeant and the People’s accident
reconstruction expert, examined Robinson’s vehicle and data from the airbag
control module of the vehicle. An airbag control module collects data from
numerous sensors in the vehicle for the purpose of determining whether or
not to deploy the airbags. Some of the data that the module collects includes
when there is a change in velocity in a rapid period of time. In this case, the
vehicle registered two events, each taking place within seconds of one
another. The airbags deployed during the first event. They did not deploy
during the second event because they had already deployed, but the change of
velocity was enough for the airbag control module to record an event.
The data indicated that leading to the first event, the throttle was at
100 percent, meaning the gas pedal was pushed down all the way. Other
data showed that there was a jump in wheel speed, suggesting that the
vehicle lost traction, which, in turn, was consistent with the vehicle going off
the roadway and catching air before hitting the ground. Additionally, during
that period, the steering wheel data showed a hard turn to the left, followed
by a hard turn to the right, and application of the brakes, consistent with the
vehicle losing control. During the second event, there was an even greater
velocity change, consistent with the vehicle being stopped or its wheels
locking up or sliding. Overall, the two events recorded were consistent with a
vehicle driving off a roadway, catching air, hitting the ground, and then
hitting something that made it come to a complete stop. Based on
photographs of the scene, Medina testified that a boulder in the immediate
area may have caused the second event.
Medina testified that hitting a person generally would not cause

12
airbags to deploy because a car weighs much more than a person. If a car is
moving fast, Medina explained, a person would be a “very low amount of force
applied to that vehicle compared to the weight and the volume—and the
energy moving down the road,” such that it would not trigger the airbag
deployment.
Medina also examined the vehicle itself and found that the damage to
front of the hood and windshield was consistent with a person having been
hit by the car.
Cell Phone Evidence
Detective Perry retrieved defendant’s cell phone and obtained his
phone records from his carrier, Verizon Wireless (Verizon). In addition to call
and text records, Verizon provided two types of cell phone location data for
defendant’s phone, as testified to by Jim Cook, the prosecution’s expert in
interpreting and mapping cell phone location data.
One type of cell phone location data was cell tower or cell site data. A
cell tower or site “is an antenna used by a carrier to facilitate the connection
between the cellular phone and the wireless network.” When a call or text is
placed or received, or a “data event” occurs, a record is created in the network
of the carrier—here Verizon. A data event is an activity by a phone, other
than a call or a text, that connects to the network; it can be passive, such as
when an application on a device decides to complete an update, or user-
initiated, such as when the user actively engages an application. Cell phones
connect to the tower with the strongest signal, which, depending on factors
including elevation and physical impediments, may not be the tower
geographically closest to the phone. For example, because of Napa’s hilly
topography, cell phone users may not always connect to the closest tower; a
different tower might provide a better line of sight to the phone. Cell tower

13
data can “show a general vicinity of coverage related to a particular call, text
or data event.”
The second type of location data was obtained from Verizon’s
proprietary software called Real Time Tool, or RTT. RTT uses an algorithm
to identify the approximate longitude and latitude of the phone. Cook
explained that the distance was calculated by Verizon based on “how long a
signal takes to get to the antenna and then back to the device.” He added
that RTT data “provides a location with a degree of accuracy . . . for calls,
texts, and data” made or received by a cell phone. Cook also confirmed that
Verizon gives this disclaimer on RTT data: “Measurements with a high
confidence factor may be more accurate than with a low confidence factor,”
meaning that their RTT data measurements are the best estimates available,
rather than precise locations.
Cook analyzed and compared location data for defendant’s phone using
cell towers and, when applicable, RTT data. With respect to the cell tower
data, Cook imported that data into a computer program that he used to map
out which cell towers defendant’s phone connected to on December 11 and 12,
2019. Cook also visited the crime scene, as well as the various cell towers
that defendant’s phone had connected to, in order to authenticate that those
towers were in place, and to determine if there were any potential
obstructions that could impact connectivity.
Cell tower data between December 11 and 12, 2019 showed defendant’s
phone connected to five towers—two on the valley floor near defendant’s
mother’s residence and Robinson’s residence in Napa, one just outside of town
on a ridge, one adjacent to a vineyard outside town (cell tower 718), and one
on top of a mountain facing the direction of the crime scene (cell tower 802).
As pertinent here, on December 11, data events on defendant’s phone

14
occurred at 10:05 p.m. These events were followed by an outbound call at
10:07 p.m. to the landline of his grandmother, with whom his mother
Deborah lived. The data events and outbound call connected to cell towers
718 and 802, respectively. According to Cook, this was consistent with the
phone being in the vicinity of where Robinson’s car went off the roadway on
Mount Veeder Road; it was not consistent with being down on the valley floor
in Napa.
Defendant’s phone also made outbound calls to his father Dan Lilly at
10:11 p.m. and 10:13 p.m. Those calls connected to cell tower 802, which
activity was also consistent with the phone being in the vicinity of the crime
scene.
At 10:25 p.m. and 10:26 p.m., defendant’s phone made outbound calls to
Robinson’s work phone. Those calls were consistent with the phone being
down on the valley floor, not in the vicinity of the crime scene.
Cook also interpreted defendant’s RTT data, which indicated that a
data event at 10:06 p.m. took place within a radius of about 17.7 miles from
cell tower 802. This was consistent with the phone being in the area of the
crash site. The call activity between 10:11 p.m. and 10:14 p.m. similarly
indicated a radius of about 17.3 miles away from cell tower 802, again
consistent with being in the crime scene area.
Cook also recounted defendant’s text records. Defendant’s phone sent a
text to Robinson’s work phone at 10:28 p.m. on December 11, stating, “Honey,
really? You’re going to leave me hanging this long. Are you serious? Where
did you go, to Santa Rosa? Please don’t leave me hanging like this.” At 11:35
a.m. the next morning, defendant’s phone sent a text to Robinson’s work
phone saying, “Heather, what is going on? You need to call somebody.
People are worried.”

15
 Cook testified that defendant’s phone was either powered off or unable
to make connection during the 13-hour period between the last call or text on
December 11 and the first call or text on December 12.
Cook further compared the GPS data from Robinson’s car with
defendant’s cell phone records and found the car’s recorded path of travel
matched with defendant’s cell phone activity. Defendant’s phone activity
between 10:05 p.m. and 10:14 p.m. was consistent with the phone having
been in the vicinity where the car went off the roadway.
Intimate Partner Battering Evidence
Melissa Kelly, an investigator with the Napa County District
Attorney’s Office, testified as an expert in the investigation of domestic
violence cases. Kelly had spoken and met with Robinson, but had never met
defendant.
Kelly discussed the “the power and control wheel,” a visual
representation that depicts certain tactics commonly used by perpetrators of
domestic violence to gain power and control over their partners. Each
“spoke” or “wedge” of the wheel corresponds to one of the eight tactics of
power and control. One of these is emotional abuse, which can take the form
of name calling, accusing the partner of cheating or other things the
perpetrator knows to be false, making the partner feel not good enough, and
“trying to make somebody feel crazy or second guess what they know to be
true by repeating something over and over and over again.” A second tactic is
isolating the partner from his or her support system, family, and friends.
A third power and control tactic is denying, minimizing, and blaming, a
tactic that is used to make the partner believe that what had happened is not
as bad as it really was. This in turn is used to keep the victim from realizing
the extent of abuse in the relationship.

16
 A fourth power and control tactic in domestic violence is using children,
such as trying to convince a partner that he or she is a bad parent or that the
children would be safer if they were not with the partner.
A fifth power and control tactic is using privilege, meaning when one
person establishes that there are rules in the relationship and that the
person who is the abuser has all the strength and decision-making powers in
the relationship, while the other person is treated as a second-class citizen or
servant.
A sixth tactic is economic abuse, which involves using money for the
purpose of keeping a partner from leaving the relationship or doing things
that the abuser doesn’t want the partner to do.
A seventh tactic of power and control is using coercion and threats,
which may or may not involve physical harm
An eighth power and control tactic is intimidation, which is similar to
threats, but does not take only the form of words. It can be more physical,
such as using a larger body size, blocking doorways to prevent access,
displaying weapons, punching walls, or destroying property that belongs to
the victim.
On this topic, the prosecutor, in the form of hypotheticals, asked Kelly
if certain behaviors exemplified some of the tactics she described. For
instance, the prosecution asked if examples of emotional abuse could include
accusing the victim of cheating or of other things the abuser knows to be
false, using the victim’s addiction and relapse against him or her, or calling
the victim derogatory names. Kelly answered such questions in the
affirmative.
Kelly testified that not all of these tactics are used in every case of
domestic violence because the dynamics of every relationship is different.

17
Some of these tactics may be used by some perpetrators, but not by others.
Some of them may not apply at all. Understanding the power and control
tactics, however, is a way for law enforcement and other professionals who
work with people in domestic violence relationships to understand why
someone is either staying in a relationship or denying there is violence in a
relationship. Kelly explained that although these power and control tactics
are often seen in domestic violence cases, “it’s not a clear-cut science that
we’re going to see this every time.”
Kelly then discussed the “cycle of violence” within a domestic violence
relationship, which cycle is broken down into three phrases. The first is the
“honeymoon” phase, during which both partners are on their best behavior
and affectionate with each other. Then, as the tension sets in, the
relationship enters the “tension-building” phase, in which you begin to see
more yelling, arguing, name calling, or putting down the other partner.
Finally, there is the “explosive” phase. In this phase, a partner may commit
actual violence, physical or sexual, against another person, or may
demonstrate a propensity for violence such as punching a wall. After the
explosive phase, the relationship reverts back to the honeymoon phase, thus
beginning the cycle of violence all over again.
Kelly explained that not every case of domestic violence ends up with
physical injury; conversely, the absence of injury does not mean a person is
not a victim of domestic violence. Kelly also testified that based on her
experience, it is not very common for a victim to report an incident of abuse
immediately after it happens. Sometimes victims delay reporting a domestic
violence incident or fail to report altogether. Kelly testified there are a
variety of reasons for the failure to report or delayed reporting. All of the
dynamics of power and control, as well as the cycle of violence, are at play. A

18
victim may want to protect the abuser, may be in love with the abuser, or
may not want the abuser to go to jail or lose his or her job. The failure to
report or delayed reporting may be out of love, fear, embarrassment, or
economic reasons. Similar reasons may also explain why victims sometimes
report, but minimize, the severity of an incident of domestic violence.
According to Kelly, there is no particular profile of a domestic violence
victim; even a strong, outspoken person could become a victim.
The Defense Case
In opening statement, defendant’s trial attorney argued there would be
no evidence “that [defendant] was behind the wheel that night whatsoever
driving the car.” Rather than demonstrating that defendant hit Robinson
with her car, counsel argued, “The evidence will show [defendant and
Robinson] left approximately 9:00 o’clock [sic] p.m. from their home. And
they go driving, and during that drive, they’re talking, they’re arguing over
money again, and again, and again, to the point where the car pulls over and
[defendant] gets out presumably to either go to the bathroom or just to get
out. And then [he’s] left at the side of the road. That’s when [Robinson]
keeps driving. Then she proceeds to drive all the way up to Mt. Veeder
ultimately going over the ravine.”
Shareen Cronin, the defense expert in blunt force trauma and
strangulation, opined that Robinson’s injuries were consistent with being hit
by a car, but that there could be other explanations for the injuries, such as
falling down from a location with height. Cronin also testified that if
Robinson’s injuries were caused by being hit by a car, one would expect to see
rashes, cuts, abrasions, or head injury.
While Cronin opined that the markings on Robinson’s lower extremities
were not consistent with being hit by a car, she testified that it is possible to

19
break a bone after being hit by a car and not necessarily have a big odious
injury. As for Robinson’s arm fracture, Cronin said such injury could be
consistent with being hit by a car and being thrown down a ravine, but that it
was also possible that the injuries were consistent with being in a car
accident.
Cronin also testified that the red markings on Robinson’s neck did not
“definitively” show she had been strangled. While the markings could
indicate strangulation, they also could have been sustained during the event
that caused her leg and arm injuries.
The defense also called Chris Kauderer, their accident reconstruction
expert, to testify. Kauderer opined that there was no damage to the outside
of Robinson’s vehicle that proved the vehicle had struck a pedestrian. He
pointed to the absence of any evidence of clothing or human biologicals, such
as skin, blood, or hair, on Robinson’s vehicle, evidence he would expect to
normally see if a vehicle had contact with a pedestrian.
Instead, Kauderer opined that the damage to the left front corner was
consistent with the vehicle striking a rock or tree while traveling down the
hillside. Kauderer could not say exactly what caused the crack on the
windshield. He believed the damage likely was also caused by the car
striking a rock or tree on its way downhill, though he did not see any debris,
mud, or tree bark on the windshield or hood.
Kauderer agreed with the prosecution’s accident reconstruction expert
that based on the airbag control module, there was an unbuckled driver in
the driver’s seat, and no one in the passenger’s seat, at the time of the
accident; the car was airborne for a period of time; and there was a second
event in which the airbags did not deploy because they already had been
deployed during the first event. Kauderer also agreed that it is not

20
uncommon for the module to register a pedestrian collision. Kauderer
confirmed that there was nothing he had reviewed in the airbag module data
that was inconsistent with the vehicle having hit a person prior to going over
the embankment and hitting the ground and then the rocks.
The Charges, the Verdict, and the Sentence
By an information filed on January 6, 2020, and amended on October 4,
2021, defendant was charged with attempted willful, deliberate, and
premeditated murder (Pen. Code, §§ 664, 187, subd. (a); count one); assault
with a deadly weapon (id., § 245, subd. (a)(1); count two); assault by means
likely to produce great bodily injury (id., § 245, subd. (a)(4); count three);
corporal injury to a spouse (id., § 273.5, subd. (a); count four); and criminal
threats (id., § 422; count five).
The information also alleged as enhancements that defendant
personally used a deadly and dangerous weapon (Pen. Code, § 12022,
subd. (b)(1)) as to count one, and personally inflicted great bodily injury in
commission of counts one and two under circumstances involving domestic
violence (id., § 12022.7, subd. (e)). As to all counts, the information alleged
appellant had suffered a prior strike conviction (id., § 667, subds. (b)–(i)) and
a prior serious felony conviction (id., § 667, subd. (a)(1)), and had served a
prior prison term (id., § 667.5, subd. (a)).
On October 5, 2021, a jury found defendant guilty on all counts and
found true all conduct enhancement allegations. The trial court found true
the prior conviction and prison term allegations.
And on November 3, the court sentenced defendant to an indeterminate
term of 14 years to life in prison, plus a determinate term of 13 years and 4
months to run consecutively to the indeterminate term.
The indeterminate term consisted of the middle term of seven years to

21
life on the count one attempted murder conviction, doubled to 14 years to life
due to the prior strike conviction.
The determinate term was comprised of the following: the middle term
of three years on count four, doubled to six years due to the prior strike; eight
months on count five (one-third of the middle term), doubled to 16 months;
one year on the weapon enhancement with respect to count one; and the
upper term of five years for the great bodily injury enhancement also with
respect to count one. The court selected the upper term for the great bodily
injury enhancement “[b]ecause of the major injuries that Ms. Robinson
suffered, the broken leg or knee, the shoulder, regarding [sic] several
surgeries.”
As to the remaining counts two and three, the court imposed their
middle terms for an aggregate sentence of five years, four months, but stayed
them pursuant to Penal Code section 654.
This timely appeal followed.
DISCUSSION
Admission of Expert Testimony on Cell Phone Location Data
Defendant first challenges the admission of testimony from the
prosecution’s wireless technology expert, Jim Cook. He contends that Cook
was not qualified to give an opinion on cell tower location data and that a
portion of Cook’s opinions was based on unreliable information. We disagree
with these contentions.
Qualification of the People’s Cell Phone Expert Witness
“A person is qualified to testify as an expert if he has special
knowledge, skill, experience, training, or education sufficient to qualify him
as an expert on the subject to which his testimony relates.” (Evid. Code,

22
§ 720, subd. (a).)2 “Against the objection of a party, such special
knowledge . . . must be shown before the witness may testify as an expert.”
(Ibid.) The witness’s expertise “may be shown by any otherwise admissible
evidence, including his [or her] own testimony.” (Id., subd. (b).) Section 801
provides that “[i]f a witness is testifying as an expert, his testimony in the
form of an opinion is limited to such an opinion as is: [¶] (a) Related to a
subject that is sufficiently beyond common experience that the opinion of an
expert would assist the trier of fact; and [¶] (b) Based on matter (including
his special knowledge, skill, experience, training, and education) perceived by
or personally known to the witness or made known to him at or before the
hearing, whether or not admissible, that is of a type that reasonably may be
relied upon by an expert in forming an opinion upon the subject to which his
testimony relates, unless an expert is precluded by law from using such
matter as a basis for his opinion.”
“The trial court is given considerable latitude in determining the
qualifications of an expert and its ruling will not be disturbed on appeal
unless a manifest abuse of discretion is shown.” (People v. Kelly (1976)
17 Cal.3d 24, 39 (Kelly); accord, People v. Nelson (2016) 1 Cal.5th 513, 536.)
“Such an abuse of discretion will be found only where ‘ “the evidence shows
that a witness clearly lacks qualification as an expert.” ’ [Citations.]”
(People v. Chavez (1985) 39 Cal.3d 823, 828, citing People v. Hogan (1982)
31 Cal.3d 815, 852, disapproved of on other grounds in People v. Cooper
(1991) 53 Cal.3d 771, 836.) “ ‘ “Where a witness has disclosed sufficient
knowledge of the subject to entitle his opinion to go to the jury, the question
of the degree of his knowledge goes more to the weight of the evidence than
its admissibility.” ’ [Citation.]” (People v. Bolin (1998) 18 Cal.4th 297, 322.)

23
 In light of the “considerable latitude” afforded a trial court in
determining the qualifications of an expert (Kelly, supra, 17 Cal.3d at p. 39),
we cannot say the trial court abused its discretion in permitting Cook to
testify as an expert in wireless technology in general and cell phone location
data in particular.
Cook began working in the cell phone industry over 30 years ago, first
as a sales representative for various cell phone companies for several years,
then as an owner of ten retail locations, and after that, as a field
representative for AT&T. While working in the cell phone industry, Cook
interfaced with and assisted a number of engineers in both erecting and fine-
tuning cell sites in order to maximize coverage. Eventually, Cook started his
own business, Premier Cellular Mapping and Analytics. Additionally, since
2006 Cook has been serving as wireless expert in court proceedings. He has
testified as an expert over 110 times on topics such as call detail records,
device exams, cell phone technology, how cell sites work, and cell phone
artifacts, such as Google search data and social media activity. Also, as a
wireless expert, Cook interprets carrier call and text message records, text
messages, and other data supplied by cell phone carriers, and based on that
information, maps out where a cell phone might be located. Cook is also a
certified instructor for the California Peace Officers Standards and Training
One and the California District Attorney’s Association, and has taught at
various conferences nationwide. For nearly 25 years, he has been teaching
the evidentiary value of a cell phone and digital evidence.
Although the defense during voir dire examination focused on Cook’s
lack of a college degree or the fact he was not an engineer, the above
demonstrates that Cook had a considerable amount of on-the-job experience
with cell phone technology, cell towers, and analyzing cell phone records,

24
which includes mapping the location of a cell phone in relation to various cell
towers.
Defendant’s counterarguments are unavailing. He claims that “Cook
had no training on how cell sites work,” and at most he only personally
observed others “test and fine tune cell sites.” These contentions are belied
by Cook’s testimony, discussed above. While working in the wireless field,
Cook did not merely observe but rather assisted engineers in erecting and
fine tuning cell sites at various locations. Further, defendant ignores that
Cook, while not an engineer himself, has been working with cell phone
technology in some capacity over the past 30 years, during which he gained
extensive experience and training on a number of topics related to cell phone
technology, including how cell towers work and how to interpret data related
to cell towers. In short, defendant cannot show Cook “ ‘ “clearly lack[ed]
qualification as an expert”’ ” in cell site location information. (People v.
Chavez, supra, 39 Cal.3d at p. 828, italics omitted.)
Accordingly, the trial court properly allowed Cook to testify as an
expert. Questions concerning the degree of Cook’s knowledge and reliability
of his testimony were explored at length before the jury, and went to the
weight of the evidence rather than its admissibility. (People v. Bolin, supra,
18 Cal.4th at p. 322.)
Reliability of the Basis of the Expert Opinion
Defendant next argues that the portion of Cook’s testimony regarding
Verizon’s RTT data should have been excluded as unreliable under
section 801. (§ 801, subd. (b) [expert testimony must be “[b]ased on matter . .
. perceived by or personally known to the witness or made known to him at or
before the hearing . . . that is a type that reasonably may be relied upon by an
expert . . .”].) By way of recap, RTT data refers to a type of location data

25
obtained from Verizon’s proprietary software that uses an algorithm to
identify the approximate longitude and latitude of a phone. Defendant
claims that because Cook did not personally verify the RTT data provided in
the cell phone records, his opinions pertaining to that data were based on
unreliable information. Defendant acknowledges he did not object to the
expert testimony on this basis below, but argues his claim is nonetheless
cognizable, because the failure to object constitutes ineffective assistance of
his trial attorney. We disagree.
As we explained in People v. Mackey (2015) 233 Cal.App.4th 32, 119:
“A defendant claiming ineffective assistance of counsel must demonstrate
both deficient performance and resulting prejudice. (Strickland v.
Washington (1984) 466 U.S. 668, 687 691–692 (Strickland); People v.
Ledesma (1987) 43 Cal.3d 171, 216–218.) On the first prong he must show
that ‘counsel’s representation fell below an objective standard of
reasonableness . . . [¶] . . . under prevailing professional norms.’ (Strickland,
supra, at p. 688.) And under the second, he must show that in the absence of
the error it is reasonably probable that a result more favorable to him would
have [been] obtained. A reasonable probability is ‘a probability sufficient to
undermine confidence in the outcome.’ (Id. at p. 694.)”
“Whether to object to inadmissible evidence is a tactical decision;
because trial counsel’s tactical decisions are accorded substantial deference
[citations], failure to object seldom establishes counsel’s incompetence.”
(People v. Hayes (1990) 52 Cal.3d 577, 621.) Thus, “[i]f the record on appeal
fails to show why counsel acted or failed to act in the instance asserted to be
ineffective, unless counsel was asked for an explanation and failed to provide
one, or unless there simply could be no satisfactory explanation, the claim
must be rejected on appeal.” (People v. Kraft (2000) 23 Cal.4th 978, 1068–

26
1069.)
Here, the record does not reflect the actual reasons why defense
counsel did not object to Cook’s testimony regarding Verizon’s RTT data. The
record, however, does disclose a conceivable tactical basis for not objecting to
such testimony. Counsel may have decided not to object to the RTT data
testimony because he wished to emphasize the flaws in Cook’s analysis on
cross-examination and closing argument. As the People note, defense counsel
on cross-examination was able to elicit testimony from Cook that Verizon had
released a disclaimer on RTT data, namely that RTT data measurements are
estimates of, rather than precise, locations of a cell phone. Additionally,
during closing argument, defense counsel reminded the jury that “Verizon
[W]ireless gives an actual disclaimer. . . . I read this to Mr. Cook, and he
agreed with it. . . . The latitude and longitude measurements on real-time
tool, that’s RTT, report are derived solely from the round-trip delay
measurement. They are best estimates and are not related to any GPS
measurement. . . . Measurements with a high-confidence factor may be more
accurate than measurements with a low-confidence factor, but all
measurements contained on this report are the best estimates available,
rather than a precise location. [¶] In other words, you can’t use cell towers to
pinpoint where someone is. Don’t fall for it.” Because the record suggests a
possible tactical basis for not objecting to the testimony on RTT data, the
ineffective assistance claim must be rejected.
But even if we believed that counsel’s conduct fell below an objective
standard of reasonableness, defendant cannot show it was prejudicial under
the second prong of Strickland.
As an initial matter, defendant does not appear to argue that his
testimony related to cell phone tower data, as opposed to RTT data, was

27
based on unreliable information. (See People v. Garlinger (2016)
247 Cal.App.4th 1185, 1187 [“expert testimony explaining a cell phone signal
received by a certain side of a cell tower must have come from that side of the
tower and in the general vicinity of the tower does not describe a new
scientific technique subject to the standard set forth by our Supreme Court in
[Kelly, supra,] 17 Cal.3d 24 for admitting the results of such techniques”].)
We acknowledge that the cell tower data is less precise than the RTT data
purported to be. Nonetheless, as now explained, because the cell tower data
established the same relevant facts as the RTT data, defendant has failed to
establish counsel’s failure to object to testimony about RTT data was
prejudicial.
As the People assert, even without testimony about Verizon’s RTT data,
the jury would have still heard testimony that cell phone tower data linked
defendant’s phone to the crime scene. Specifically, the cell phone tower data
demonstrated that data events recorded on, and calls made from, defendant’s
phone between 10:05 p.m. and 10:13 p.m. on December 11, 2019—minutes
after Robinson’s car was recorded to have suffered a catastrophic event at
10:01 p.m.—connected to cell towers located in the vicinity of where the car
went off the road on Mount Veeder Road. This evidence raised a strong
inference that defendant was near the crime scene around the time
Robinson’s car fell off the roadway.
Apart from Cook’s testimony, other evidence presented by the
prosecution strongly, if not overwhelmingly, connected defendant to the
charged crimes. And the defense case was weak in comparison. Robinson’s
testimony stands as direct evidence that defendant assaulted and attempted
to murder her on December 11, 2019. There was circumstantial evidence
that amply corroborated Robinson’s testimony. This included the testimony

28
of several witnesses, including medical personnel and law enforcement,
regarding Robinson’s injuries when she was found the morning after the
incidents, as well as the testimony of an orthopedic surgeon who found her
injuries consistent with being hit by a car and tumbling down an
embankment. GPS data from Robinson’s vehicle also matched her
description of her vehicle’s path of travel on the night in question. In
addition, damages to Robinson’s vehicle were consistent with it having hit a
person. On top of all that, as discussed further below, defendant had an
apparent motive to kill Robinson: his anger towards her for calling and
threatening to call his parole officer and his determination not to go back to
prison.
Accordingly, we conclude that defense counsel’s failure to object to
testimony about the RTT data did not prejudice defendant. Defendant has
thus failed to establish his counsel rendered ineffective assistance.
Admission of Evidence of Prior Domestic Violence
Defendant next argues the trial court abused its discretion in admitting
evidence of uncharged domestic violence incidents that occurred before the
charged incidents in this case.
Additional Background
Prior to trial, the People moved in limine to introduce evidence of prior
incidents of domestic violence. The first was in October 2015, when
defendant beat Robinson and choked her. The next set of incidents occurred
in November 2019, when defendant broke her phone and then later hurt her
arm in attempt to keep her from leaving her apartment.
At oral argument on the motion, defense counsel objected to the
evidence on section 352 grounds. Over that objection, the trial court allowed
the evidence to come in. Robinson, as well as her coworkers and friend, gave
testimony pertaining to the two prior incidents.
29
 The Law
Section 1101, subdivision (a) provides that “evidence of a person’s
character or a trait of his or her character . . . is inadmissible when offered to
prove his or her conduct on a specified occasion.” Section 1109,
subdivision (a)(1) provides an exception to that rule: “[I]n a criminal action
in which the defendant is accused of an offense involving domestic violence,
evidence of the defendant’s commission of other domestic violence is not made
inadmissible by Section 1101 if the evidence is not inadmissible pursuant to
Section 352.” (See People v. Villatoro (2012) 54 Cal.4th 1152, 1159.)
And under section 352, the trial court has discretion to exclude
evidence “if its probative value is substantially outweighed by the probability
that its admission will (a) necessitate undue consumption of time or (b) create
substantial danger of undue prejudice, of confusing the issues, or of
misleading the jury.” “ ‘In applying section 352, “prejudicial” is not
synonymous with “damaging.” ’ ’’ (People v. Karis (1988) 46 Cal.3d 612, 638
(Karis).) Instead, prejudice under section 352 refers to evidence “ ‘which
uniquely tends to evoke an emotional bias against the defendant as an
individual and which has very little effect on the issues.’ ’’ (Karis, at p. 638;
see People v. Rucker (2005) 126 Cal.App.4th 1107, 1119.)
If evidence is admitted under section 1109, and by extension,
section 352, a trier of fact may infer from the evidence that the defendant had
a disposition or propensity to commit other offenses involving domestic
violence, and that the defendant was likely to commit and did commit the
current domestic violence offense. (See People v. Ogle (2010) 185 Cal.App.4th
1138, 1143; People v. Johnson (2010) 185 Cal.App.4th 520, 528.)
We review a challenge to a trial court’s decision to admit such evidence
for abuse of discretion. (People v. Hamilton (2009) 45 Cal.4th 863, 929–930;

30
People v. Branch (2001) 91 Cal.App.4th 274, 281–282.) As to what a showing
of such abuse requires, it has been described in terms of a decision that
“exceeds the bounds of reason” (People v. Beames (2007) 40 Cal.4th 907, 920),
or one that is arbitrary, capricious, patently absurd, or even whimsical. (See,
e.g., People v. Bryant, Smith and Wheeler (2014) 60 Cal.4th 335, 390
[“ ‘ “arbitrary, capricious, or patently absurd” ’ ”]; People v. Benavides (2005)
35 Cal.4th 69, 88 (Benavides) [ruling “ ‘ “falls ‘outside the bounds of
reason’ ” ’ ”].)
Analysis
In support of his claim that the trial court abused its discretion in
admitting evidence of prior domestic violence, defendant asserts three sub-
arguments: first, that the court failed to address all the factors it was
purportedly required to weigh in determining whether to admit the evidence
under section 352; second, that the evidence was inadmissible under
section 352 in any event; and third, that the evidence was not justified by the
purposes underlying section 1109. We address each argument in turn.
On the first sub-argument, “when ruling on a section 352 motion, a
trial court need not expressly weigh prejudice against probative value, or
even expressly state that it has done so. All that is required is that the
record demonstrate the trial court understood and fulfilled its responsibilities
under . . . section 352.” (People v. Williams (1997) 16 Cal.4th 153, 213;
accord, People v. Padilla (1995) 11 Cal.4th 891, 924 [“[A]s the cases reflect,
we are willing to infer an implicit weighing by the trial court on the basis of
record indications well short of an express statement”], overruled on other
grounds in People v. Hill (1998) 17 Cal.4th 800, 823, fn. 1.)
The record here so demonstrates. During oral argument on the
People’s motion in limine to admit evidence of the prior domestic violence

31
incidents, defense counsel objected to the evidence pursuant to section 352.
The court responded, “I’m going to grant the request that [Robinson] may
testify about the 2015 and 2019 . . . incident occurring prior to the issue in
question.” The prosecutor then attempted to raise another point regarding
the prior incidents, but was interrupted when the court had an off-the-record
discussion with the clerk. When the court went back on the record, it then
allowed defendant and his attorney to have further off-the-record discussions
regarding the evidence. The court then went back on the record and stated,
“The objection is noted and the Court has ruled those two incidents may be
testified about by the alleged victim.” Although the trial court did not
expressly weigh prejudice against probative value, we may infer from its
acknowledgment of defendant’s objection based on section 352 and its
decision to admit the evidence over that objection that it was aware of the
section 352 issue and thus its weighing duty under the statute. (See People v.
Williams, supra, 16 Cal.4th at p. 214.)
This leads us to defendant’s second sub-argument that the admission of
the evidence of prior domestic violence incidents “violated Section 352.”
Citing People v. Nguyen (2010) 184 Cal.App.4th 1096, 1117, defendant argues
that the following factors weighed in favor of excluding the evidence of prior
domestic violence: “(1) the probative value of the uncharged acts, which
includes a consideration whether the acts increased in frequency and
severity; (2) whether the uncharged acts are remote; (3) the degree of
certainty that the uncharged acts actually occurred; (4) whether the jury
would be tempted to punish the defendant for the uncharged acts, thus
confusing the issues; (5) whether the uncharged acts are cumulative on the
issue of propensity; (6) whether admission will consume an undue amount of
time.” We disagree.

32
 Despite defendant’s contentions otherwise, the probative value of the
evidence was great. The prior acts of domestic violence involving defendant
were substantially similar—they all involved arguments and threats of
violence against Robinson and resulted in physical injury to her. The 2015
incident was especially similar in that it involved defendant beating and
choking Robinson.
In addition, the prior incidents were not remote in time. The October
2015 incident occurred within five years of the charged incidents. The
November 2019 incidents occurred in the month before the charged incidents.
Moreover, although Robinson was the only direct witness of the prior
incidents, the testimony of her coworkers and friend regarding their
observations following the incidents gave Robinson’s version of the incidents
independent reliability. (See People v. Ewoldt (1994) 7 Cal.4th 380, 404–405
(Ewoldt), superseded by statute on other grounds as stated in People v. Britt
(2002) 104 Cal.App.4th 500, 505.) They testified that after each incident
Robinson had injuries consistent with having been beaten, appeared
emotionally distraught, and expressed fear of defendant.
On the other side of the scale, defendant argues that the prejudicial
effect of this evidence is heightened by the circumstance that defendant’s
uncharged acts did not result in criminal convictions, because such
circumstance may have increased the danger that the jury might have been
inclined to punish defendant for the uncharged offenses, regardless whether
it considered him guilty of the charged offenses, and increased the likelihood
of confusing the issues.
At the same time, however, the testimony describing defendant’s
uncharged acts was no stronger and no more inflammatory than the
testimony concerning the charged offenses. “This circumstance decreased the

33
potential for prejudice, because it was unlikely that the jury disbelieved
[Robinson’s] testimony regarding the charged offenses but nevertheless
convicted defendant on the strength of . . . [Robinson’s] testimony regarding
the uncharged offenses, or that the jury’s passions were inflamed by the
evidence of defendant’s uncharged offenses.” (Ewoldt, supra, 7 Cal.4th at
p. 405.)
Lastly, as defendant acknowledges, “[e]vidence about these incidents
and their aftermath did not consume an inordinate amount of time.”
Considering all of the circumstances, we conclude the trial court did not
abuse its discretion in declining to exclude evidence of defendant’s prior
domestic violence under section 352. It follows the court properly admitted
the evidence under section 1109.
We are not convinced otherwise by defendant’s argument that the
admission of the evidence “was not justified by the purposes behind
Section 1109.” (Capitalization omitted.) He cites People v. Brown (2000) 77
Cal.App.4th 1324, 1333, which references a bill analysis in the legislative
history of section 1109 stating: “Proponents argue that in domestic violence
cases, as in sexual offense cases, special evidentiary rules are justified
because of the distinctive issues and difficulties of proof in this area.” Such
difficulties of proof, defendant continues, are reflected by “ ‘uncooperative
victims’ ” who “ ‘may refuse to testify, who recant previous statements, or
whose credibility is attacked by defense questions on why they remained in a
battering relationship.’ ” (People v. Brown (2004) 33 Cal.4th 892, 899
(Brown).) Defendant argues that “[t]here were none of these ‘difficulties of
proof’ in this case,” because Robinson took the stand at trial and did not
recant her statements concerning the incidents. Nor did the defense,
defendant contends, question why Robinson stayed with Martin despite the

34
prior abuse.
Preliminarily, we note that defendant did not object to the evidence on
this basis, thereby forfeiting his claim on appeal. Section 353 requires a
party’s objection to evidence to be “timely made and so stated as to make
clear the specific ground of the objection.” (§ 353, subd. (a).) The Supreme
Court has “ ‘consistently held that the “defendant’s failure to make a timely
and specific objection” on the ground asserted on appeal makes that ground
not cognizable. [Citations.]’ ” (People v. Partida (2005) 37 Cal.4th 428, 434
(Partida).) Notwithstanding defendant’s forfeiture of his argument under
section 1109, we reject it on the merits.
As a general matter, the authority defendant cites does not establish
the proposition that evidence of prior domestic violence incidents is
admissible under section 1109 only where the alleged victim refuses to testify
or recants his or her statements, or where the victim’s credibility is
questioned on the basis of the victim remaining in a battering relationship.
In any event, contrary to defendant’s assertions, the “difficulties of proof” he
refers to were presented in this case. The record demonstrates that defense
counsel did attack Robinson’s credibility based on her failure to report the
prior incidents and her decision to stay in a relationship with defendant. On
cross-examination of Robinson, defense counsel questioned her about why she
did not report to police or take photos of her injuries from the incidents and
how she married defendant even after the first incident in 2015. Defense
counsel maintained this theme throughout closing statements. We thus
reject defendant’s argument that the admission of such evidence “was not
justified by the purposes of section 1109.”
But even assuming the evidence was improperly admitted, any such
error was harmless under the standard set forth in People v. Watson (1956)

35
46 Cal.2d 818 (Watson). (See People v. Marks (2003) 31 Cal.4th 197, 226–227
[“the application of ordinary rules of evidence like Evidence Code section 352
does not implicate the federal Constitution, and thus we review allegations of
error under . . . Watson”]; accord, People v. Fudge (1994) 7 Cal.4th 1075,
1102–1103.) Under the Watson standard, an error is prejudicial only if “it is
reasonably probable that a result more favorable to the [defendant] would
have been reached in the absence of the error.” (Watson, supra, 46 Cal.2d at
p. 836.)
Here, it is not reasonably probable that defendant would have obtained
a favorable verdict had the court excluded evidence of the prior domestic
violence incidents. As explained above, evidence of defendant’s guilt was
strong. (See ante, pp. 30–31.) Furthermore, the court instructed the jury
that they could consider evidence of the prior domestic violence, but for a
limited purpose. It gave CALCRIM No. 352A, which permits but does not
require the jury to infer that the defendant was predisposed to commit the
charged crime if the jury finds by a preponderance of the evidence that the
defendant committed uncharged domestic violence. It admonishes that a
finding of prior domestic violence is not sufficient by itself to prove the
defendant guilty of the charged crime; such a finding, should it be made, is
only one factor to be considered with the other evidence. And this instruction
clearly states that the prosecution must still prove “each charge and
allegation beyond a reasonable doubt.”
Given these circumstances, we see no reasonable possibility of a verdict
more favorable to defendant, even in the absence of the testimony about prior
domestic violence.
For the first time on appeal, defendant also claims the trial court’s
evidentiary ruling violated his due process rights. Assuming this claim was

36
preserved on appeal, it fails. It is well established that “generally, violations
of state evidentiary rules do not rise to the level of federal constitutional
error.” (Benavides, supra, 35 Cal.4th at p. 91; accord, People v. Jones (2013)
57 Cal.4th 899, 957 [“the routine application of provisions of the state
Evidence Code law does not implicate a criminal defendant’s constitutional
rights”].) Here, “[t]he trial court did not err under state law, and defendant
does not provide any persuasive reason for us to conclude that the application
of California’s rules of evidence violated his constitutional rights, nor does he
establish any basis for concluding that the admission of this evidence
rendered the jury’s . . . verdict unreliable.” (People v. Prince (2007) 40 Cal.4th
1179, 1238–1239 (Prince).)
Admission of Expert Testimony on Intimate Partner Battering
Defendant’s third evidentiary challenge is that the trial court abused
its discretion in admitting expert testimony concerning the effects of intimate
partner battering.
Additional Background
Prior to trial, the prosecution moved in limine to admit such evidence
under section 1107. The prosecution’s justification for doing so was that
“[t]here are many myths and misperceptions about domestic violence in our
society, about why a victim may refuse to report violence, even lie to protect
his or her partner, and why a victim would stay with his or her abuser. . . .
The People are requesting an expert witness to educate the jury in general
about domestic violence, types of violence, and common patterns and cycles of
violence, as well as strangulation within domestic violence.”
During argument on the motion, defense counsel stated, “I’ll lodge an
objection, just for the record, on that one.” The court admitted the proposed
expert testimony over that objection.
As detailed above, Melissa Kelly, an investigator with the Napa County
37
District Attorney’s Office, testified for the prosecution as an expert in
intimate partner violence. She explained the “power and control tactics” of
abusers that are commonly seen in domestic violence cases she has
investigated. She also testified as to the “cycle of violence” in abusive
relationships between intimate partners. Additionally, Kelly testified that
victims, for various reasons, often stay in a relationship despite being abused.
Similarly, she testified that victims often fail to report or delay in reporting
incidents of abuse for various reasons.
The Law
Section 801 permits expert testimony “[r]elated to a subject that is
sufficiently beyond common experience that the opinion of an expert would
assist the trier of fact.” (§ 801, subd. (a).) Section 1107 concerns a specific
type of expert opinion testimony. It states expert testimony concerning
“intimate partner battering and its effects, including the nature and effect of
physical, emotional, or mental abuse on the beliefs, perceptions, or behavior
of victims of domestic violence” is admissible in a criminal action “except
when offered against a criminal defendant to prove the occurrence of the act
or acts of abuse which form the basis of the criminal charge.” (§ 1107,
subd. (a).)
“The effects of intimate partner battering, frequently, albeit inartfully,
referred to as ‘battered women’s syndrome,’ have been defined as ‘ “ ‘a series
of common characteristics that appear in women [or men] who are abused
physically and psychologically over an extended period of time by the
dominant male [or female] figure in their lives.’ ” ’ ” (In re Walker (2007)
147 Cal.App.4th 533, 545–546 & fn. 11, citing People v. Humphrey (1996)
13 Cal.4th 1073, 1083−1084 (Humphrey); see People v. Romero (1994)
8 Cal.4th 728, 735, fn. 1 [“the effects of intimate partner battering manifest

38
as ‘ “a ‘pattern of responses and perceptions presumed to be characteristic of
[individuals] who have been subjected to continuous physical abuse by their
mate[s]’ ” ’ ”].)
There are two components to the relevance analysis in this context.
First, there must be sufficient evidence to support the theory that the effects
of intimate partner battering applies to the victim. (People v. Gadlin (2000)
78 Cal.App.4th 587, 592 (Gadlin).) Second, there must be a contested issue to
which the testimony is probative, other than whether a criminal defendant
committed charged acts of domestic violence. (Ibid.)
Expert testimony on intimate partner battering is generally relevant
and admissible “to explain that it is common for people who have been
physically and mentally abused to act in ways that may be difficult for a
layperson to understand.” (People v. Riggs (2008) 44 Cal.4th 248, 293 (Riggs);
see People v. Kovacich (2011) 201 Cal.App.4th 863, 903 [“expert testimony on
domestic violence may include general descriptions of abuser behavior in
order to ‘explain the victim’s actions in light of the abusive conduct’ ”].) “The
relevance of this evidence is based on the possibility that the jurors will doubt
that a witness who claims to have been abused has indeed acted in the
manner to which he or she testified, and therefore the jurors might
unjustifiably develop a negative view of the witness’s credibility.” (Riggs,
supra, 44 Cal.4th at p. 293, citing Brown, supra, 33 Cal.4th at pp. 906–908;
see Humphrey, supra, 13 Cal.4th at p. 1087 [intimate partner battering
evidence may assist the jury by dispelling commonly held misconceptions
about battered victims, including that victims are free to leave their abusers
at any time].)
As with the other evidentiary rulings challenged by defendant, the trial
court’s decision to admit the expert testimony is reviewed for abuse of

39
discretion. (See Prince, supra, 40 Cal.4th at p. 1222; People v. Kovacich,
supra, 201 Cal.App.4th at p. 902.)
Analysis
Defendant raises essentially three arguments challenging the
admissibility of the intimate partner battering evidence. First, he contends
the evidence lacked foundation and was irrelevant under section 1107.
Second, he argues the evidence was inadmissible under section 801 because
the subject of intimate partner battering is not beyond the common
experience of jurors. Third, defendant maintains that the expert testimony
constituted improper profile evidence.
As a threshold matter, the People contend that defendant has forfeited
all of these contentions because his counsel at trial did not raise objections on
the grounds asserted on appeal. Defense counsel stated he was “lodg[ing] an
objection” to admitting the evidence at issue, but he did not specify any
grounds for the objection. As noted, an objection to evidence that does not
specify the ground asserted on appeal makes that ground not cognizable.
(Partida, supra, 37 Cal.4th at p. 434; § 353, subd. (a).) Thus, defendant’s
failure to specify any grounds for his objection to the expert testimony, much
less the grounds raised on appeal, renders his appellate claims not
cognizable.
Even if we were to reach the merits of defendant’s claims, we find them
unpersuasive.
We first disagree with defendant that the evidence on the effects of
intimate partner battering lacked foundation and was not relevant under
section 1107. He argues “the evidence was not probative on a contested
issue,” because the prosecution “presented little evidence the behaviors Kelly
described, such as rationalization, failure to report crimes, recantation,

40
reconciliation, had any impact on Robinson’s response to the charged
offense[s] and the defense did not lean on these behaviors to attack
Robinson’s credibility.” In a related argument, defendant asserts the
evidence was not relevant because “the prosecutor did not show there was a
common myth or misconception Kelly’s testimony would rebut” in connection
with the charged offenses.
Initially, we note defendant does not deny that the evidence at trial
suggested Robinson’s and defendant’s relationship involved a struggle for
power and control between them, or a “cycle of violence,” as described by
Kelly. In addition, defendant agrees that Kelly’s testimony was relevant to
explain her “earlier failures”: her delay in reporting the prior domestic
violence incidents and resuming her relationship with defendant despite the
violence. Yet, defendant claims that Robinson’s decision to promptly report
the charged incidents and cooperate with the prosecution at trial somehow
rendered Kelly’s testimony irrelevant under section 1107. This argument
fails.
Even if Robinson did not fail to report the charged incidents, her
credibility nonetheless remained at issue, in light of her “earlier failures” to
promptly report the uncharged incidents and her decision to stay in a
relationship despite the violence. And, contrary to defendant’s assertions
otherwise, the defense at trial did challenge Robinson’s credibility on those
grounds. The People correctly observe that “[a]s part of its defense strategy
of discrediting Robinson’s account of what happened on December 11,
[defendant’s] counsel argued that she lied in her testimony about [defendant]
harming her on the two prior occasions.” As explained above, defense counsel
on cross-examination of Robinson questioned her regarding her failure to
report the prior incidents and decision to marry defendant despite the abuse.

41
Counsel stuck with this theme during closing argument, focusing on
Robinson’s failures to immediately report the prior incidents. Additionally,
defense counsel questioned Robinson’s state of mind at the time of the
charged incidents, arguing that she did not act in a manner consistent with
her stated fear of defendant. Counsel argued, “[I]f you’re so afraid that
[defendant’s] going to kill you, why get in the car with him and have him
drive?” Rather than someone fearful of defendant, counsel described
Robinson as “suicidal,” thus suggesting she voluntarily had driven her car
down the ravine.
Thus, Kelly’s expert testimony was relevant to explain Robinson’s
behaviors that were seemingly inconsistent with her testimony about
suffering abuse, and therefore, to assess her credibility. (See Riggs, supra,
44 Cal.4th at pp. 293–294; Humphrey, supra, 13 Cal.4th at pp. 1087–1088.)
In other words, the evidence was probative to show Robinson was a battered
victim at the time of both the uncharged and charged incidents.
Gadlin, a case defendant cites, actually undermines his position.
There, the court held that expert testimony on intimate partner battering
was relevant, even when the victim was not recanting at trial, but
cooperating with the prosecution. (Gadlin, supra, 78 Cal.App.4th at pp. 594–
595.) The defendant and victim had “a troubled, ‘off-again, on-again’
relationship for two and one-half years . . . .“ (Id. at p. 590.) In June 1993,
the defendant came home under the influence of drugs, tried to choke the
victim, dragged her into a bedroom, and was holding a knife to her neck when
police arrived. The victim later wrote a letter of recantation to the parole
board on defendant’s behalf. Following a one-year period of incarceration for
a parole violation, defendant and the victim reunited. In July 1994, when the
victim tried to end the relationship, the defendant pushed her to the floor;

42
grabbed a knife; and cut the victim from her temple to the middle of her
cheek and on her back, neck, abdomen; and he cut three of her fingers. (Ibid.)
The defendant was charged with, and later convicted of, assault with a
deadly weapon based on the 1994 incident. (Id. at pp. 589, 590.)
Gadlin held that intimate partner battering evidence “was probative
regarding both the victim’s recantation of a prior incident and her decision to
resume the relationship with the defendant before the charged incident.”
(Gadlin, supra, 78 Cal.App.4th at p. 589.) It explained, “Both sides sought
admission of the prior incident, and the recantation was pivotal in the
defense attack on the victim’s credibility.” (Id. at p. 594.) The defense
attacked the victim’s credibility in opening statement, throughout trial, and
in closing statement. (Ibid.) The court explained that the expert testimony
“was properly admitted here despite the victim’s cooperation with the
prosecution at the trial because the attack on her credibility was based on her
state of mind at the time of the charged and uncharged incidents. . . . [T]he
victim was a battered woman at that time.” (Ibid.)
Gadlin is analogous to this case. Here, as in Gadlin, the victim’s
credibility was a critical issue. The evidence showed that Robinson
responded to her abuse by defendant in ways that a layperson might view as
inconsistent with an abused victim—she failed to report prior incidents of
abuse and continued to remain in an intimate relationship with defendant.
Also, the defense in this case expressly contested Robinson’s credibility along
these lines. Thus, as in Gadlin, the expert testimony on intimate partner
battering was properly admitted despite Robinson’s cooperation with the
prosecution at trial, because the attack on her credibility was based on her
state of mind at the time of the charged and uncharged incidents. The court

43
here thus properly admitted Kelly’s testimony under section 1107.3
Turning to the argument under section 801, defendant claims that the
effects of intimate partner battering is not a proper subject for expert
testimony because it is not beyond the common knowledge of jurors. (§ 801,
subd. (a) [expert testimony admissible if it is “[r]elated to a subject that is
sufficiently beyond common experience”].) Defendant contends that because
the public is more aware today of the dynamics of domestic violence than it
was when section 1107 was enacted in 1991, the prosecution failed to show
that Kelly’s testimony was beyond the common knowledge of the average
juror. This argument lacks merit. The use of expert testimony to explain the
effects of intimate partner battering is statutorily authorized by section 1107.
As such, the Legislature has determined that intimate partner battering is a
proper subject for expert testimony. Further, our Supreme Court has upheld
the admission of such expert testimony under section 1107 or section 801, or
both. (See Humphrey, supra, 13 Cal.4th at p. 1088; Brown, supra, 33 Cal.4th
at pp. 895–896, 905.) As the People assert, defendant’s assertion essentially

3 Defendant’s citations to cases outside the context of intimate partner
battering do not assist his position. People v. Lavergne (1971) 4 Cal.3d 735 is
readily distinguishable, as it held that a party may not cross-examine a
witness on irrelevant matters for the purpose of eliciting something to be
contradicted. This rule does not apply here because Robinson was not
impeached on a collateral matter. Defendant also cites People v. Jones (2013)
57 Cal.4th 899 for the proposition that “a party must present more than
argument about the myth or misconception it seeks to rebut.” But here, as
explained, there was evidence, not merely argument, that certain
misconceptions surrounding victims of domestic violence were at play. Even
further removed from the issue are People v. Bonin (1988) 46 Cal.3d 659, 698
and People v. Wilson (2005) 36 Cal.4th 309, 354, which dealt with the failure
to instruct on the meaning of the penalty “life without possibility of parole”
and thus had nothing to do with the admissibility of intimate partner
battering evidence or other similar type of psychological evidence.
44
“is a policy argument that should be directed to the Legislature. This court’s
function is to interpret the law, not pass on its wisdom.”
Finally, we disagree with defendant that Kelly’s testimony should have
been excluded as improper profile evidence. “A profile ordinarily constitutes
a set of circumstances—some innocuous—characteristic of certain crimes or
criminals, said to comprise a typical pattern of behavior. In profile testimony,
the expert compares the behavior of the defendant to the pattern or profile
and concludes the defendant fits the profile.” (Prince, supra, 40 Cal.4th at p.
1226.)
Defendant relies primarily on People v. Robbie (2001) 92 Cal.App.4th
1075, 1084 (Robbie), which holds that “[p]rofile evidence is generally
inadmissible to prove guilt.” In Robbie, the defendant was charged with
kidnapping for sexual purposes and other sex offenses. (Id. at pp. 1077–
1078.) At trial, the defendant maintained that his sexual encounter with the
victim was consensual. (Id. at pp. 1079–1080.) In an effort to overcome this
defense, the prosecution offered an expert on sexual offenders “to testify
that . . . defendant’s conduct was consistent with being a rapist.” (Id. at p.
1081.) In the form of hypothetical questions asked by the prosecutor, the
expert testified that many rapists use only minimal force, and described in
detail a scenario in which the rapist is in effect acting as if he thinks of the
sexual acts as consensual. (Id. at pp. 1082–1084.) Not coincidentally, the
behavior the expert described matched the testimony of the alleged victim.
Then, when asked “what if any conclusion do you reach about that conduct?”
the expert answered, “That it’s the most prevalent type of behavior pattern
that I have seen with sex offenders. It’s the most common type of behavior
pattern.” (Id. at p. 1083.) The Court of Appeal in Robbie characterized this
evidence as inadmissible “profile evidence.” It explained: “[The evidence]

45
implies that criminals, and only criminals, act in a given way. In fact, certain
behavior may be consistent with both innocent and illegal behavior, as the
People’s expert conceded here.” (Id. at p. 1085.)
The court in Robbie distinguished its case from People v. McAlpin
(1991) 53 Cal.3d 1289 (McAlpin). (Robbie, supra, 92 Cal.App.4th at pp. 1086–
1087.) In McAlpin, the defendant who was accused of child molestation
presented extensive evidence showing he was a respectable member of the
community. A police officer with experience in child molestation
investigations testified for the prosecution that there is no profile of a typical
child molester; a child molester “can be of any social or financial status, any
race, any age, any occupation, any geographical origin, and any religious
belief or no religious belief at all,” as well as “persons of good or even
impeccable reputations in the community.” (McAlpin, supra, 53 Cal.3d at
p. 1299.) Our Supreme Court held the trial court properly admitted this
evidence because it refuted a common stereotype of child molesters. (Id. at
pp. 1300, 1302–1304.) The Robbie court explained, “The evidence in McAlpin
was not admitted for [an] improper purpose. It was not offered to establish a
stereotype, then condemn the defendant for fitting it. Instead, the McAlpin
evidence was admitted in recognition that a misleading notion existed in the
public consciousness and to disabuse jurors of the misconception.” (Robbie, at
p. 1087.)
In our view, the expert testimony here is closer to McAlpin than to
Robbie. The gist of Kelly’s testimony about perpetrators of domestic violence
was that there was no profile of a typical perpetrator. Kelly described, in
general fashion, tactics used by abusers to exert power and control over their
victims that are commonly seen in domestic violence cases. It is true that
Kelly was asked in the form of hypotheticals to consider examples of

46
behaviors that paralleled Robinson’s descriptions of defendant’s conduct
towards her. However, this testimony was always given in the context of
explaining the impact such behaviors would likely have on a victim. As she
put it, the “power and control tactics wheel” is a tool to “help . . . understand
why someone is either staying in a relationship or denying that there is
violence in a relationship. So this is a . . . visual relationship of some tactics
that we will often see but it’s not . . . a clear-cut science that we’re going to
see this every time.” In addition, Kelly who had never met defendant, did not
suggest that any behaviors that could be attributed to defendant were the
“most prevalent” or the “most common” type seen in abusers. Nor did she
offer an opinion as to whether such behaviors established that defendant was
an abuser. Instead, Kelly explained that not all of the power and control
tactics are present in every case of domestic violence, because “[t]he dynamics
of every relationship is different.” “[S]ome of these tactics may be used by
some perpetrators of domestic violence and not by others. Some of them may
not apply.” She also explained that not every domestic violence case involves
physical injury. Additionally, Kelly testified there is no particular profile of a
domestic violence victim. Thus, even though parts of Kelly’s testimony
appear at first blush to fit the “profile” mold, in fact they do not.
For similar reasons, defendant also misplaces reliance on People v.
Martinez (1992) 10 Cal.App.4th 1001 (Martinez). There, the defendant was
arrested for driving a stolen truck. (Id. at p. 1003.) The Martinez court held
the trial court erred in permitting the prosecution to introduce the testimony
of highway patrol investigators regarding theft rings that transported stolen
vehicles to Central America to prove the defendant knew the car he bought
was stolen. (Id. at pp. 1007–1008.) Here, as we have already stated, Kelly’s
testimony was not used to show that defendant fit the profile of a criminal

47
and therefore he was guilty of the crimes charged.
But even if Kelly’s testimony amounted to profile evidence under
Robbie or Martinez, this did not mean her testimony was inadmissible.
Robbie and Martinez predate our Supreme Court’s decision in People v. Smith
(2005) 35 Cal.4th 334 (Smith), disapproved on another ground in People v.
Beck and Cruz (2019) 8 Cal.5th 548, 670. The court in Smith explained that
“ ‘[p]rofile evidence’ . . . is not a separate ground for excluding evidence”; like,
other evidence, it is admissible “only if it is either irrelevant, lacks a
foundation, or is more prejudicial than probative.” (Smith, supra, 35 Cal.4th
at p. 357.) Two years later, in Prince, the Supreme Court quoted that
passage from Smith and reiterated that “profile evidence does not describe a
category of always-excluded evidence,” but rather is subject to exclusion only
if it meets the criteria set forth in Smith. (Prince, supra, 40 Cal.4th at
p. 1226.)
Thus, under Smith and contrary to Robbie and Martinez, classifying
certain testimony as profile evidence is not sufficient to establish its
inadmissibility. Rather, the testimony must still be shown to be inadmissible
on some other ground, such as relevance, foundation, or prejudicial effect that
outweighs its probative value. As noted, defendant did not object to the
admissibility of profile evidence on any of those grounds in the trial court, so
he has forfeited any such objections. (Partida, supra, 37 Cal.4th at p. 434.)
Likewise, on appeal, he does not argue that the evidence was more
prejudicial than probative. Although he does argue on appeal that the
evidence lacked foundation and was irrelevant, we have rejected those
contentions above. Defendant therefore has not shown that the evidence was
inadmissible under Smith, by which we are bound.
In any event, assuming the admission of the purported profile evidence

48
was erroneous, it was harmless. In Robbie and Martinez, the admission of
the profile evidence was not harmless because each case was closely
balanced. (See Robbie, supra, 92 Cal.App.4th at pp. 1087–1088 [both the
victim and the defendant testified at trial, giving “starkly conflicting versions
of events”; the victim admitted lying about certain events; and other
witnesses testified that she was untruthful and that she used drugs];
Martinez, supra, 10 Cal.App.4th at p. 1008 [“[t]he issue of defendant’s
knowledge and intent, being dependent upon circumstantial evidence, was
close”].) Also, in Robbie, the only evidence corroborating the victim’s claim of
rape (contrasted with the defendant’s claim of consensual sex) was a witness
who said the victim had mentioned the defendant’s white truck while talking
on the phone the evening of the alleged rape, and other witnesses who
described her as upset after the incident. (Robbie, at pp. 1077–1078, 1088.)
Here, on the other hand, there was significant evidence that amply
corroborated Robinson’s account of the charged incidents, as discussed above.
(See ante, pp. 30–31.)
Further, contrary to defendant’s assertions, the prosecutor’s statements
during closing argument did not urge the jury to find defendant guilty based
on Kelly’s testimony. Although the prosecutor drew parallels between the
power and control tactics described by Kelly and defendant’s actions, she did
so for the purpose of explaining Robinson’s apparently self-impeaching
behaviors. The prosecutor stated, “You . . . heard from Investigator Melissa
Kelly, who talked about both the power and control wheel and the cycle of
violence to help give some context to some of [Robinson’s] decisions and the
experiences she was having in this relationship and why she acted the way
she did.” She continued, “You see—and we mentioned the cycle of abuse so
that you understand [Robinson], why she kept going back to this relationship,

49
why she stayed. She told you how much she loved him, and how much she
thought things might change.” Read in context, the prosecutor’s argument
was that Robinson’s delay in disclosing prior incidents of abuse and her
resumption of a relationship with defendant did not necessarily indicate that
her allegations should be discredited.
In short, any error in admitting expert testimony on intimate partner
battering was harmless.
Failure to Sua Sponte Instruct the Jury with CALCRIM No. 850
Defendant argues the trial court erred in failing to sua sponte instruct
the jury with CALCRIM No. 850, which states, in pertinent part: “Testimony
as to [the effects of intimate partner battering] is offered only to explain
certain behavior of an alleged victim of domestic abuse. [¶] [It] is not
evidence that the defendant committed any of the crimes charged against
[Robinson] [or any conduct or crime[s] with which [defendant] was not
charged]. [¶] You may consider this evidence only in deciding whether or not
[Robinson’s] conduct was consistent with the conduct of someone who has
been abused and in evaluating the believability of (her) testimony.”
The bench notes to CALCRIM No. 850 discuss a court’s instructional
duty: “Several courts of review have concluded there is no sua sponte duty to
give a similar limiting instruction (see CALCRIM No. 1193, Testimony on
Child Sexual Abuse Accommodation Syndrome [(CSAAS)]) when an expert
testifies on child sexual abuse accommodation syndrome. [Citations.]” The
bench notes cite several cases, including, among others, People v. Mateo
(2016) 243 Cal.App.4th 1063, 1073–1074 (Mateo), which held that the trial
court was required to give CALCRIM No. 1193 only upon request, and
Humphrey, supra, 13 Cal.4th at p. 1088, fn. 5, which states, “If the
prosecution offers the battered women’s syndrome evidence, an additional

50
limiting instruction might also be appropriate on request . . . .” The bench
notes also cite People v. Housley (1992) 6 Cal.App.4th 947, 958–959 (Housley),
in which a panel of this Division concluded there is a sua sponte duty to give
a CALCRIM No. 1193.
Defendant argues that our Supreme Court’s statement in Humphrey is
mere dictum. The People argue that our holding in Housley is “out of step
with other authority” and, in any event, “[d]icta of our Supreme Court are
highly persuasive” (People v. Wade (1996) 48 Cal.App.4th 460, 467) and
should be followed. We need not decide whether the trial court was required
to give CALCRIM No. 850 absent a request because, in the circumstances of
this case, it is not reasonably probable that the result would have been
different had the court given the instruction. (See Mateo, supra, 243
Cal.App.4th at p. 1074 [even assuming court erred in failing to give limiting
instruction on CSAAS, error was harmless under Watson standard]; Housley,
supra, 6 Cal.App.4th at p. 959 [reaching similar conclusion].)
The Mateo court concluded no prejudice was shown by the failure to
instruct, reasoning that “[w]here, as here, the expert testifies regarding the
behavior of abused children as a class, there is little, if any, chance the jury
will misunderstand or misapply the evidence.” (Mateo, supra,
243 Cal.App.4th at p. 1074.) In Housley, we concluded that, even if a sua
sponte instruction had been provided, there was no reasonable probability of
a more favorable result because the CSAAS testimony was presented in
general terms, it was clear that the expert had no contact with the victim or
knowledge of the underlying facts, and under such circumstances the jury
would not have misunderstood or misapplied the expert testimony as proof
that the victim was in fact sexually abused. (Housley, supra, 6 Cal.App.4th
at p. 959.)

51
 Similarly, in this case, it is not likely the jury was misled or confused
by Investigator Kelly’s testimony on intimate partner battering. As
explained ante, Kelly stated she did not meet defendant, her testimony was
couched in general terms, and she did not express any opinion as to whether
defendant had committed the charged or uncharged incidents. Her testimony
was provided within the context of explaining the impact certain behaviors
would likely have on a victim, rather than characterizing the abuser. As was
the portion of the prosecutor’s closing argument recounting Kelly’s testimony.
Moreover, the jury was instructed that it was not required to accept the
expert’s opinions as true or correct, that it had to determine the meaning and
importance of any opinion, and that it could disregard any opinion that it
found unbelievable, unreasonable, or unsupported by the evidence. Given
these circumstances, it is not reasonably probable the jury would have
reached a different verdict had it been instructed with CALCRIM No. 850.
Admission of Evidence of Prior Conviction, Incarceration, and
Parole Status
Defendant next contends the trial court should have excluded evidence
of his prior robbery conviction, prior incarceration, and status as a parolee as
irrelevant and unduly prejudicial under section 352.
Additional Background
One of the People’s motions in limine sought to admit, pursuant to
section 1101, subdivision (b), two robberies defendant committed in 2007 and
2015 to prove that the attempted murder was premeditated rather than the
product of mistake or accident. Separately, the People sought to introduce
evidence of defendant’s incarceration between 2015 and 2019 to provide the
context of his and Robinson’s relationship during that period, in particular to
explain why there had been no domestic violence incidents between them.
Finally, the People sought to admit evidence of defendant’s parole status to

52
establish his motive to kill Robinson: his anger towards Robinson for having
called and threatening to call his parole officer and his fear of being
apprehended and going back to prison.
During oral argument on the admissibility of this evidence, the People
additionally argued the evidence of the prior robberies was relevant to show
“identity, the fact that [defendant] has engaged in violent acts previously.”
Defense counsel objected to the evidence on the grounds that it was
irrelevant, and its probative value was outweighed by its prejudicial impact.
With respect to the robberies, counsel argued they were not relevant because
they were not similar to the charged incidents and defendant’s identity was
not at issue in this case.
Over these objections, the court permitted the prosecution to introduce
evidence of defendant’s incarceration and parole status. Such evidence, the
court found, was probative, because “it is very important to know why there
were no other incidents during this time frame.” It also found that the
probative value of the evidence was not outweighed by its prejudicial effect.
The court also allowed the prosecution to present evidence of only one of the
two robbery convictions for the purpose of explaining the basis of defendant’s
incarceration.
At trial, Robinson testified that defendant was imprisoned for robbery
between 2015 and 2019, during which time they got married. The jury also
saw the video of Robinson’s interview with police at the hospital stating that
defendant went to prison for robbing a convenience store. In addition,
Robinson testified that she previously had called and threatened to call
defendant’s parole officer on several occasions.
The Law
Evidence is relevant if it has “any tendency in reason to prove or

53
disprove any disputed fact that is of consequence to the determination of the
action.” (§ 210.) Section 352 applies to all relevant evidence, and a trial
court may exclude evidence when its probative value is outweighed by the
risk of undue prejudice. (People v. Castro (1985) 38 Cal.3d 301, 307; § 352.)
“Character evidence, sometimes described as evidence of a propensity
or disposition to engage in a type of conduct, is generally inadmissible to
prove a person’s conduct on a specified occasion.” (People v. Villatoro, supra,
54 Cal.4th at p. 1159; § 1101, subd. (a).) Character evidence includes
“evidence of specific instances of [a person’s] conduct.” (§ 1101, subd. (a).)
“Our Supreme Court has explained that propensity evidence is
prohibited not because it is irrelevant, but because it ‘ “ ‘is said to weigh too
much with the jury and to so overpersuade them as to prejudge one with a
bad general record and deny him a fair opportunity to defend against a
particular charge. The overriding policy of excluding such evidence . . . is the
practical experience that its disallowance tends to prevent confusion of
issues, unfair surprise and undue prejudice.’ ” ’ (People v. Jackson (2016)
1 Cal.5th 269, 300.)” (People v. Jones (2018) 28 Cal.App.5th 316, 323.)
Section 1101, subdivision (b), however, clarifies that evidence of a
person’s conduct is admissible when that evidence is relevant to demonstrate
a fact other than character or propensity, “such as motive, opportunity,
intent, preparation, plan, knowledge, identity, absence of mistake or
accident.” (§ 1101, subd. (b); Ewoldt, supra, 7 Cal.4th at p. 393.)
We review for abuse of discretion the trial court’s ruling on relevance
and admission of the evidence of the prior instances of conduct. (People v.
Wallace (2008) 44 Cal.4th 1032, 1057; People v. Cole (2004) 33 Cal.4th 1158,
1195.)
Analysis

54
 We first address the admissibility of the evidence regarding defendant’s
prior incarceration and parole status.
With regard to evidence of his prior incarceration, defendant contends
it was irrelevant because “Robinson did not recant or refuse to testi[fy] or do
anything that made her account of the charged crimes incongruous. She had
failed to report the two prior incidents, but her failure to report those were
not central to her credibility. . . . There was no need to provide the context of
their relationship to show who was more credible.”
Defendant’s argument is a rehash of his earlier assertions regarding
the evidence of intimate partner battering. We rejected those assertions,
explaining that Robinson’s credibility was placed at issue, not only by the
evidence showing she may have acted in ways inconsistent with a victim of
abuse, but also by the defense’s explicit attacks on her credibility on that
basis. And evidence that defendant had been incarcerated for a period of
time during their relationship was relevant to assessing Robinson’s
credibility. As the People argue, “Without knowing the full context of their
relationship, the jury would not understand why Robinson did not end the
relationship after the incidents in 2015, why there were no abusive incidents
between 2015 and 2019, or why Robinson’s demeanor at work suddenly
changed in 2019. Instead, they might be misled to believe Robinson and
[defendant] had repaired their relationship after one bad incident and had
shred a harmonious relationship until the month leading up to December
11[, 2019].” We agree with the People that the challenged evidence cleared
the relatively low bar for relevance under section 210.
Also, evidence of defendant’s incarceration, coupled with evidence of his
parole status, was separately relevant to the issue of motive. A theory of the
prosecution was that the attempted murder was motivated by defendant’s

55
anger at Robinson for calling and threatening to call his parole officer and his
determination not to go back to prison. The evidence showed that prior to the
incidents on December 11, 2019, Robinson had called and threatened to call
defendant’s parole officer; defendant was angry towards her as a result; he
called her a “snitch” and told her that snitches “end up in ditches,” she was
“done,” he knew “how to get rid of bodies”; and he insisted he was “not going
back to prison.” As defendant acknowledges, courts have held that evidence
of a defendant’s parole status or prior incarceration may be relevant to show
the defendant committed a crime out of a motive to avoid apprehension. (See
People v. Fuiava (2012) 53 Cal.4th 622, 668 [evidence of defendant’s parole
status admissible to show he knew his actions were illegal and that “he shot
at Deputies . . . in order to avoid being apprehended and returned to prison”],
citing People v. Heishman (1988) 45 Cal.3d 147, 168–169 [prior conviction
and sentence properly admitted to show “defendant had in fact been ‘in jail
on a rape charge’ and, thus, to help prove defendant’s motive for killing
[victim], to keep from going back to prison”], abrogated on another ground in
People v. Diaz (2015) 60 Cal.4th 1176, 1190; People v. Durham (1969)
70 Cal.2d 171, 187–189 [“There is ample authority for the admission of
evidence of prior criminal activity when such evidence provides considerable
circumstantial proof of the actor’s mental state at the time of the charged
offense”].)
Defendant nonetheless argues that the evidence was not relevant
because his “fear of returning to prison could have been presented without
reference to his parole status.” However, defendant fails to explain how, and
we are not persuaded that, the availability of other evidence renders the
evidence at issue here irrelevant.
Turning to the section 352 strand of his argument, defendant claims

56
“[t]he link between [his] incarceration and any permissible purpose was . . .
weak, whether the evidence is considered as providing context for the
relationship or explaining the absence of incidents from 2015 through 2019.”
He then asserts, “The inference from [his] status as a parolee is stronger, but
could have been supplied by other evidence.” Defendant additionally argues
that evidence of his incarceration and parole status was inflammatory in that
it “could easily influence the jury’s evaluation of the defense and could even
color their consideration of Robinson’s credibility.”
Defendant overlooks the great probative value of the evidence. The
evidence of defendant’s prior incarceration was probative on Robinson’s
credibility, a critical issue in this case. And the evidence of his parole status,
together with his prior incarceration, bore directly upon his mental state at
the time of the charged crimes. Further, defendant’s conclusory assertions
that the evidence was inflammatory fails to demonstrate that the trial court
acted outside the bounds of reason in determining that the probative value of
the evidence was not substantially outweighed by any prejudicial effect. In
any event, we are not convinced that the evidence was inflammatory or
substantially likely to elicit an impermissible emotional response from the
jury. Evidence that defendant had been incarcerated, was on parole, and did
not want to go back to prison “was not so emotionally charged as to inhibit its
logical evaluation by the jury.” (People v. Mendoza (2011) 52 Cal.4th 1056,
1092 [rejecting similar argument that evidence of a defendant’s parole status
should have been excluded under section 352].) The court thus did not abuse
its discretion in admitting evidence of defendant’s prior incarceration and
parole status.
We next address the admissibility of defendant’s prior robbery
conviction. Defendant contends the evidence was not relevant under

57
section 1101, subdivision (b) to show “identity, [or] absence of mistake or
accident.” The People concede that the court’s admission of the prior robbery
conviction “was arguably erroneous” because “[p]roving the absence of
accident or mistake, or identity, [was] unnecessary.” The People continue,
“[Defendant’s] defense was not that he hit Robinson, or that if Robinson were
not telling the truth, the driver was someone else. [His] defense was that he
was not there during the incident at all.” The People, however, argue that
any error in admitting the evidence was harmless.
Given the People’s concession, we will proceed on the assumption that
the trial court erred by admitting evidence of the prior robbery conviction.
However, we agree with the People that any such error was harmless.
Robinson’s testimony about defendant’s robbery conviction was brief, and
presented within the broader context of her relationship with defendant.
Also, as defendant recognizes, “the prosecutor did not focus on this evidence
as much as the domestic violence material.” The record does not show that
the prosecutor mentioned the prior robbery in closing summation. Rather, it
was defense counsel who referred to the robbery in an attempt to establish
defendant had no involvement in the charged incidents. Counsel argued that
while defendant may have had “a history of a robbery,” he had “no history of
domestic violence.” Finally, as we have already stated, the evidence of
defendant’s guilt was strong. (See ante, pp. 30–31.) Considering the strength
of the case against defendant, as well as the brief references to the prior
robbery, we perceive no reasonable probability of a different result if the
evidence had not been admitted.
Exclusion of Defendant’s Out-of-Court Statements
Defendant next contends the trial court abused its discretion in
excluding hearsay statements he made to his parents on the evening of

58
December 11. He argues the statements were admissible under section 1240,
the hearsay exception for spontaneous statements. He further asserts the
exclusion of his statements deprived him of his federal constitutional right to
present a complete defense.
Additional Background
In opening statements, defense counsel argued that on the night of
December 11, 2019, Robinson had left defendant on the side of the road at
some unspecified location on the valley floor in Napa, before she drove her car
up the hill on Mount Veeder Road and then off the roadway and over the
ravine. Defense counsel, on cross-examination of defendant’s father Dan
Lilly, attempted to elicit testimony to that end. Counsel questioned Lilly
regarding a phone call defendant had made to him at around 10:10 p.m. on
December 11. Lilly testified that during the call defendant “was talking loud.
He wasn’t yelling per se, but he was talking loud because of the static” before
the call dropped. When defense counsel asked, “And what did he say?” the
prosecution objected on hearsay grounds. Defense counsel countered that it
fell under the “excited utterance” exception to hearsay. The court sustained
the objection, but stated it would revisit the issue at a later time.
Also during cross examination of defendant’s mother Deborah Martin,
defense counsel asked her if defendant had told her anything when he
arrived at her house the night of December 11. This line of questioning was
again met with objections on hearsay grounds, which objections the court
sustained.
During a break in the trial, the court addressed the extrajudicial
statements. Defense counsel made the following offer of proof: “Dad would
say that he heard his son after receiving a phone call that [Robinson] just left
me on the side of the road.” The court then asked, “And what would mom

59
testify?” Counsel responded, “For the most part, the same thing that . . . he
got left on the side of the road.” Counsel offered the statements of defendant
as “an excited utterance,” arguing that “[i]t’s a starling event being left on the
side of the road in the middle of the rain.”
The prosecutor objected, arguing defendant was not permitted to
present “self-serving statements” and there was no evidence to support a
finding they qualified as spontaneous statements. The court agreed with the
prosecutor, concluding, “I would be excluding it because it is self-serving and
the law is . . . clear on that issue, that that can’t be introduced in that
manner.”
Analysis
Addressing defendant’s evidentiary challenge first, the express basis
for the court’s ruling was that defendant’s statements were “self-serving.”
The court did not expressly address whether the statements qualified as
spontaneous statements under section 1240. Thus, it is not entirely clear if
the court excluded the evidence also on hearsay grounds. It appears
exclusion solely on the ground the statements were self-serving would have
been improper. It is true that self-serving extrajudicial declarations by
criminal defendants, not otherwise admissible under an exception to the
hearsay rule, are not admissible for the truth of the matter asserted. (See
People v. Gurule (2002) 28 Cal.4th 557, 605–606; People v. Clay (1984) 153
Cal.App.3d 433, 457; People v. Cruz (1968) 264 Cal.App.2d 350, 361.)
However, the fact that a statement is self-serving does not preclude its
introduction under an appropriate hearsay exception, such as the
spontaneous statement exception. (See Lane v. Pacific Greyhound Lines
(1945) 26 Cal.2d 575, 581–582; Oiye v. Fox (2012) 211 Cal.App.4th 1036,
1050;; People v. Cruz, supra, 264 Cal.App.2d at pp. 359–360, 363; People v.

60
Haskell (1960) 185 Cal.App.2d 267, 269–273; 10 Witkin, Cal. Evidence (5th
ed. 2022) § 10.)
Assuming arguendo the trial court erred in excluding the statements,
we conclude any such error was harmless. Had defendant’s statements been
admitted, there is no reasonable probability the verdict would have been
more favorable to him. At the time defendant made the statements, he had a
powerful motive to lie. Although the self-serving nature of the statements
may not have been a proper basis for its exclusion, as discussed above, it
surely would have made the statements less credible to the jury. There was
no corroboration for defendant’s statements that he had been abandoned on
the side of the road. On the other hand, as explained above, there was strong
evidence that connected defendant to the charged crimes. (See ante, pp. 30–
31.) Indeed, defendant’s explanation that he had been abandoned on the side
of the road falters alone on the evidence of his cell phone activity, which, as
noted, placed him in the vicinity of the crime scene minutes after Robinson’s
car fell off the roadway. Moreover, the jury, in finding defendant guilty
beyond a reasonable doubt attempted of premediated murder and the other
charges, necessarily rejected the defense’s overall theory that someone other
than defendant had driven Robinson’s car off the roadway. In sum,
defendant’s abandonment theory was highly implausible, and there is no
reasonable probability it would have been credited by the jury even if his self-
serving statements had been admitted.
We also reject defendant’s claim that the exclusion of his extrajudicial
statements violated his federal constitutional right to present a complete
defense. His reliance on cases such as Holmes v. South Carolina (2006) 547
U.S. 319 (Holmes) and Chambers v. Mississippi (1973) 410 U.S. 284
(Chambers) is misplaced. At issue in Holmes was “whether a criminal

61
defendant’s federal constitutional rights are violated by an evidence rule
under which the defendant may not introduce proof of third-party guilt if the
prosecution has introduced forensic evidence that, if believed, strongly
supports a guilty verdict.” (Holmes, supra, 547 U.S. at p. 321.) Holmes held
that this rule was “ ‘arbitrary,’ ” reversed the judgment, and remanded for
further proceedings. (Id. at p. 331.) Here, defendant does not even attempt
to argue the trial court’s reliance on California’s hearsay restrictions can be
equated or even analogized to the South Carolina rule at issue in Holmes.
In Chambers, the defendant was charged with murder, but another
person confessed to friends that he was the killer and later signed a sworn
confession. When called as a witness by the defense, however, the person
repudiated his confessions. The state court prevented the defense from
impeaching its own witness under an antiquated state rule of evidence, and
excluded the confessions because Mississippi had no exception to the hearsay
rule for statements against penal interest. (Chambers, supra, 410 U.S. at
pp. 291–295, 299.) The United States Supreme Court concluded that the
defendant’s right to due process had been violated because the evidence was
critical, and the combination of two dubious rules of evidence compelled the
state court to ignore overwhelming indicia that the hearsay confessions were
reliable. (Id. at pp. 297–298, 302– 303.) The court emphasized that the
confessions were spontaneous and corroborated by other evidence, including
eyewitness testimony. (Id., at pp. 294, 300.)
Chambers, however, “was an exercise in highly case-specific error
correction.” (Montana v. Egelhoff (1996) 518 U.S. 37, 52.) “[T]he holding of
Chambers—if one can be discerned from such a fact-intensive case—is
certainly not that a defendant is denied ‘a fair opportunity to defend against
the State’s accusations’ whenever ‘critical evidence’ favorable to him is

62
excluded, but rather that erroneous evidentiary rulings can, in combination,
rise to the level of a due process violation.” (Id. at p. 53; accord, People v.
Ayala (2000) 23 Cal.4th 225, 269.)
This is not an unusual case like Chambers. The trial court here did not
apply any “antiquated” evidentiary rule like the “voucher” rule in Chambers.
Also, defendant had a meaningful opportunity to present a defense, even in
the absence of his statements. Rather than a refusal to allow defendant to
present a defense, the court here merely rejected certain evidence concerning
his defense. Although Chambers “ ‘determined that the combination of state
rules resulting in the exclusion of crucial defense evidence constituted a
denial of due process under the unusual circumstances of the case before it, it
did not question “the respect traditionally accorded to the States in the
establishment and implementation of their own criminal trial rules and
procedures.” (Chambers . . , supra, 410 U.S. at pp. 302–303.’ ” (People v.
Abilez (2007) 41 Cal.4th 472, 503.) Here, the exclusion of evidence was a
garden-variety evidentiary issue and thus did not implicate defendant’s
federal constitutional right to present a defense. (Ibid.) Further, defendant
has not shown his statements bore persuasive assurances of trustworthiness
similar to the statements in Chambers, which were made spontaneously to a
friend shortly after the murder occurred, were unquestionably against the
declarant’s interest, and were corroborated by other evidence in the case.
(Chambers, at pp. 291–293, 300, 301.) Accordingly, defendant has failed to
demonstrate a due process violation.
Cumulative Prejudice
Defendant contends a combination of errors rendered his trial
fundamentally unfair, requiring reversal. “[A] series of trial errors, though
independently harmless, may in some circumstances rise by accretion to the

63
level of reversible and prejudicial error.” (People v. Hill, supra, 17 Cal.4th at
p. 844.) To the extent that there are instances in which we assumed the
existence of error, we concluded that no prejudice resulted from any such
error. When considered cumulatively, those assumed errors provide no basis
for reversal. (See People v. Potts (2019) 6 Cal.5th 1012, 1058; People v. Rogers
(2006) 39 Cal.4th 826, 911.)
Sentencing Issues
Finally, defendant contends, and the People agree, that his sentence
must be vacated and his case remanded for resentencing due to recently
enacted legislation that took effect after he was sentenced: Assembly Bill
No. 518 (2021–2022 Reg. Sess.) (Assembly Bill 518) and Senate Bill No. 567
(2021–2022 Reg. Sess.) (Senate Bill 567). We accept the People’s concessions.
Turning to the more recent legislation, effective January 1, 2022,
“Senate Bill 567 amended [Penal Code] section 1170, subdivision (b) to
specify that, when a sentencing court chooses a term from a statutory triad,
the chosen term shall not exceed the middle term, unless the facts supporting
the aggravating circumstances are (1) established by the defendant’s
stipulation to them, (2) proven to a jury (or to a court, if jury is waived)
beyond a reasonable doubt, or (3) based on prior convictions evidenced by a
certified record of conviction. (Stats. 2021, ch. 731, §§ 1.3, 3(c), adding Pen.
Code, § 1170, subd. (b)(1)–(3), by amendment.)” (People v. Jones (2022)
79 Cal.App.5th 37, 44 (Jones).)
Assembly Bill 518, another recent enactment that took effect on
January 1, 2022, amended Penal Code section 654 to provide in relevant part:
“An act or omission that is punishable in different ways by different
provisions of law may be punished under either of such provisions, but in no
case shall the act or omission be punished under more than one provision.”

64
(Stats. 2021, ch. 441, § 1.) “ ‘Previously, under section 654, “the sentencing
court was required to impose the sentence that provides for the longest
potential term of imprisonment and stay execution of the other term.
[Citation.] . . . [S]ection 654 now provides the trial court with discretion to
impose and execute the sentence of either term, which could result in the
trial court imposing and executing the shorter sentence rather than the
longer sentence.” ’ ” (Jones, supra, 79 Cal.App.5th at p. 45.)
The parties agree that aspects of defendant’s sentence are potentially
affected by these amendments. The trial court, applying the pre-Senate Bill
No. 567 version of Penal Code section 1170, subdivision (b), imposed the
upper term of five years for the domestic violence great bodily injury
enhancement (Pen. Code, § 12022.7, subd. (e)) in connection with count one.
In selecting the upper term, the court relied on a factor in aggregation—great
bodily harm to Robinson—that was not admitted by defendant or found by
the jury to be true beyond a reasonable doubt. And, applying the pre-
Assembly Bill 518 version of Penal Code section 654, the court imposed and
executed the term applicable to the count one attempted murder conviction,
while imposing but staying the terms applicable to the assault convictions on
counts two and three.
We agree with the parties that defendant is entitled to retroactive
application of the ameliorative changes affected by Senate Bill 567 and
Assembly Bill 518. (People v. Flores (2022) 73 Cal.App.5th 1032, 1039
(Flores).) We also agree with the parties that remand is necessary for the
court to resentence defendant in accordance with those changes in the law.
(See Flores, supra, 73 Cal.App.5th at p. 1039; People v. Mani (2022) 74
Cal.App.5th 343, 381.) Finally, we agree with the People that on remand the
sentencing court “is free to conduct a full resentencing.” (See Jones, supra,

65
79 Cal.App.5th at p. 46 [“Although we are not reversing any of [defendant’s]
convictions or ruling that a portion of his sentence is invalid . . . , we conclude
the need to apply amended sections 1170, subdivision (b), and 654 creates
sufficiently ‘ “ ‘changed circumstances’ ” ’ . . . to warrant a full resentencing”],
quoting People v. Buycks (2018) 5 Cal.5th 857, 893.)
DISPOSITION
The judgment of conviction is affirmed. Defendant’s sentence is
vacated, and the matter is remanded to the trial court so that it may
resentence defendant in accordance with Senate Bill 567 and Assembly
Bill 518.
