v.
THE CITY OF SEATTLE, a municipality;
JASON M. ANDERSON, an individual;
STEVEN A. MCNEW, an individual,
Respondent.
ANDRUS, A.C.J. — On June 18, 2017, Seattle Police Officers Jason Anderson
and Steven McNew (the Officers) shot and killed Charleena Lyles after, as the Officers
contend, she threatened them with a knife. Retired Commissioner Eric Watness,
personal representative of Lyles’s estate, and Karen Clark, guardian ad litem for Lyles’
four minor children (referred here jointly as the Estate), sued the City of Seattle (the
City) and the Officers alleging negligence and assault. The trial court granted the
Officers’ motion for summary judgment, denied the Estate’s motion for partial
summary judgment on certain affirmative defenses, and struck the Estate’s three
No. 79480-9-I/2
expert declarations. Because there remain genuine issues of material fact, we reverse
and remand for further proceedings consistent with this opinion.
FACTUAL BACKGROUND
In the six months prior to her death, Charleena Lyles called the Seattle Police
Department (SPD) twenty-three times. On June 5, 2017, SPD responded to one of
Lyles’s calls in which she reported she had been the victim of domestic violence at
her apartment in an affordable housing complex owned by Solid Ground. Police
reports indicate that while officers were in her apartment, Lyles—who was present
with her young daughter—“armed herself with a pair of extra long metal shears and
was threatening [responding] officers.” Lyles reportedly told officers, “Ain’t none of
y’all leaving here today.” Both officers present drew their firearms and commanded
her to drop the scissors to the floor. Lyles reportedly yelled, “[A]re you going to shoot
me in front of my daughter?” The police reported that Lyles refused to put down the
shears even after being repeatedly asked to do so. They told Lyles they were there
to help her, not to shoot her.
Additional police officers responded to the scene and reported that during this
incident, Lyles made several unusual comments, including wanting to “morph into a
wolf” and talking about “cloning her daughter.” The police described Lyles making
several “unusual religious comments” and accusing the officers of being “devils” and
members of the Ku Klux Klan. Officers were ultimately able to convince Lyles to take
a seat on her sofa and to drop the scissors.
The police reports further indicate the officers separated Lyles and her young
child from the scissors and obtained a phone number for a nearby family member who
-2-
No. 79480-9-I/3
arrived at Lyles’s apartment shortly thereafter. They then took Lyles into custody.
The police learned from Lyles’s sister that Lyles had experienced “a recent sudden
and rapid decline in her mental health.” The police report described Lyles as
exhibiting “[d]isorientation/confusion,” “[d]isorganized speech/communication,”
“[d]isorderly/disruptive behavior,” and “[b]izarre, unusual behavior.” They described
her as “[b]elligerent/uncooperative, angry,” “[o]ut of touch with reality,” and
experiencing “[h]allucinations/delusions.” The incident led the officers to flag Lyles
and her address with an “officer safety caution.” The police booked Lyles into jail for
harassment but recommended her case be transferred to mental health court.
On the morning of June 18, 2017, Lyles called 911 to report a residential
burglary. Lyles informed police that three hours earlier, she had discovered her
apartment door open and an Xbox missing. Seattle Police Officer Jason Anderson,
on routine patrol, responded to the call and conducted a routine record check on the
address. After Officer Anderson noted the officer safety caution associated with Lyles
and reviewed the police report of the June 5 incident, he requested back up from
another unit. When Officer McNew arrived, the two officers briefly discussed the prior
incident. Officer McNew commented they should not let Lyles get behind them or get
between the officers and her apartment door.
When the Officers contacted Lyles in her apartment, she was calm and
cooperative. Lyles told the Officers she had left her apartment unlocked while she
went to the store and returned to find her Xbox or PlayStation taken. She led the
Officers down a hall to a back bedroom from which she reported items had been
stolen. After returning to the kitchen, the officers noticed two young children playing
-3-
No. 79480-9-I/4
in the living room. As Officer Anderson asked Lyles to clarify some information for his
report, he glanced up and saw Lyles lunge at him with a knife. 1 Officer Anderson
testified that had he not jumped back, Lyles would have stabbed him. He drew his
firearm and told Lyles to get back. Officer Anderson testified Lyles was yelling at them
but he could not make out what she was saying.
Officer Anderson testified Lyles then turned her attention toward Officer
McNew, who was then cornered in her kitchen. Officer McNew asked Officer
Anderson to use his stun gun. 2 Officer Anderson responded that he did not have his
stun gun. 3 The Officers both testified that Lyles continued to approach them, knife in
hand, ignoring their commands to get back. Believing Lyles intended to stab one of
them, both Officers repeatedly fired their service firearms at Lyles, killing her.
SPD’s investigation into the police shooting revealed that Lyles had a black-
handled knife with a four and one-half inch blade in her left jacket pocket and a knife
sheath in her right jacket pocket. Police recovered a second knife, with a four-inch
blade, near Lyles’s apartment door. This knife matched the size and shape of the
sheath in Lyles’s pocket.
1
Although the Estate refuses to stipulate to the facts as presented by the Officers, it has not presented
any evidence to dispute their account of Lyles’s actions in her apartment immediately before the
shooting. We therefore accept this account as undisputed.
2
The witnesses use the word “Taser,” but we refer to the device generically as a “stun gun.” We
intend to use the two words interchangeably here.
3
Officer Anderson was certified to carry and deploy a stun gun. Under Seattle Police Department
policy, once certified, a police officer is required to carry his stun gun. Following the shooting, Officer
Anderson received a two-day suspension for his failure to carry his stun gun device with him on patrol
that day.

The Estate brought this lawsuit alleging common law negligence and assault. 4
The City and the Officers asserted a number of affirmative defenses, including
immunity under RCW 4.24.420, qualified immunity, assumption of risk, and
discretionary immunity.
The City and Officers moved for summary judgment, principally arguing the
Officers owed no legal duty to Lyles under the public duty doctrine and that they were
immune from suit under Washington’s felony defense statute, RCW 4.24.420. The
Estate opposed this motion and moved to dismiss the affirmative defenses of qualified
immunity and assumption of risk and the City’s discretionary immunity defense, and
submitted declarations from three expert witnesses, two in police conduct and
practices and one in forensic psychology.
The admissibility of the experts’ testimony is a key issue in this appeal.
Criminologist Thomas Mauriello opined that the Officers’ use of their firearms was
unreasonable in light of the circumstances and contrary to SPD policies on de-
escalation. Police practices expert D.P. Van Blaricom opined that Lyles’s death could
have been avoided had Officer Anderson been carrying his SPD-mandated stun gun
and used it, rather than his firearm, to subdue Lyles. Criminal psychologist, Dr. Mark
Whitehill, opined that Lyles was in a psychotic state during the shooting and did not
have the capacity to form the intent to assault the Officers. The Officers moved to
strike these declarations as inadmissible under ER 702 and Frye v. U.S., 293 F. 1013
(D.C. Cir 1923). The trial court granted the Officers’ motion to strike the expert
4
The suit also alleged a violation of the Washington Law against Discrimination (WLAD) and violation
of article I section three of the State Constitution. The trial court granted the Officers’ CR 12(b)(6)
motion to dismiss the WLAD and constitutional claims and the Estate has not appealed that order.

declarations and granted their summary judgment motion. It denied the Estate’s
partial summary judgment motion. The Estate appeals all three orders. 5
ANALYSIS
Appellate courts review a summary judgment order de novo and perform the
same inquiry as the trial court. Borton & Sons, Inc. v. Burbank Properties, LLC, 196
Wn.2d 199, 205, 471 P.3d 871 (2020). A moving party is entitled to summary
judgment “if the pleadings, depositions, answers to interrogatories, and admissions
on file, together with the affidavits, if any, show that there is no genuine issue as to
any material fact.” CR 56(c). We view all facts and reasonable inferences in the light
most favorable to the non-moving party. Owen v. Burlington N. Santa Fe R.R. Co.,
153 Wn.2d 780, 787, 108 P.3d 1220 (2005).
Although appellate courts generally review a decision to exclude expert witness
testimony at trial under an abuse of discretion standard, State v. Arndt, 194 Wn.2d
784, 798, 453 P.3d 696 (2019), the de novo standard of review applies when reviewing
trial court evidentiary rulings made in conjunction with a summary judgment motion.
Folsom v. Burger King, 135 Wn.2d 658, 663, 958 P.2d 301 (1998). We review a trial
court’s Frye ruling de novo. Advanced Health Care, Inc. v. Guscott, 173 Wn. App.
857, 871, 295 P.3d 816 (2013).
A. Public Duty Doctrine
The Estate first argues its claims are not barred by the public duty doctrine.
The Estate alleges the Officers acted unreasonably and violated SPD policy during

The City has a separate summary judgment motion on file but the trial court has stayed further
proceedings pending this appeal.

No. 79480-9-I/7
their encounter with Lyles by failing to use nonlethal force. It contends the police
officers could have used nonlethal methods, such as a stun gun or a police baton, to
disarm Lyles or to subdue her without having to shoot her. The core of its case is that
the Officers unreasonably failed to follow police practices on the use of nonlethal
weapons calculated to avoid the use of deadly force. We agree that this claim is not
barred by the public duty doctrine.
“When the defendant in a negligence action is a governmental entity, the public
duty doctrine provides that a plaintiff must show the duty breached was owed to him
or her in particular, and was not the breach of an obligation owed to the public in
general.” Munich v. Skagit Emergency Comm’n Ctr., 175 Wn. 2d 871, 878, 288 P.3d
328 (2012). The recent Supreme Court decision in Beltran-Serrano v. City of Tacoma,
193 Wn.2d 537, 549, 442 P.3d 608 (2019), is dispositive on the inapplicability of the
public duty doctrine in this case. In Beltran-Serrano, a Tacoma Police Department
officer shot a mentally ill homeless man after the officer approached him about
panhandling in the city. Id. at 540-41. When the man, who did not understand English,
ran from the officer, she shot him multiple times. Id. Beltran-Serrano brought an
action for assault, battery, and negligence, arguing that the officer unreasonably
escalated the situation, resulting in Beltran-Serrano’s death. Id. at 542.
The City of Tacoma argued the officer owed no duty to Beltran-Serrano under
the public duty doctrine. Id. at 542. The Supreme Court disagreed, reasoning that
“every individual owes a duty of reasonable care to refrain from causing foreseeable
harm in interactions with others. . . . This duty applies in the context of law enforcement
and encompasses the duty to refrain from directly causing harm to another through
-7-
No. 79480-9-I/8
affirmative acts of misfeasance.” Id. at 550. The court held that “Beltran-Serrano's
negligence claims arise out of Officer Volk's direct interaction with him, not the breach
of a generalized public duty.” Id. at 551.
As in Beltran-Serrano, the Estate’s claims arise out of the Officers’ direct
interaction with Lyles and not the breach of a generalized public duty. The Officers
argue Beltran-Serrano is factually distinguishable because the police officer in that
case approached Beltran-Serrano unsolicited, whereas here, Officers Anderson and
McNew responded to Lyles’s request for police assistance. The Officers suggest the
holding in Beltran-Serrano was premised on the fact that Beltran-Serrano had enlisted
no help from Officer Volk. But Beltran-Serrano cannot be read so narrowly. The
Supreme Court unequivocally held that when a police officer has a direct interaction
with a plaintiff, that officer has a duty to act with reasonable care. Id. There is nothing
in the case to suggest that this duty only exists when the direct interaction is the result
of an unsolicited social contact.
The Officers further argue that they did not owe Lyles a legal duty of care
because when they responded to her report of a burglary, she was able to converse
with them coherently, she suddenly and without provocation attacked them, and the
Officers had the right under RCW 4.24.420 to respond with force. But this argument
conflates the concept of whether officers owe a legal duty to exercise reasonable care
in interacting with others and whether officers are statutorily immune from civil liability
for using lethal force when defending themselves from an assault.
While there are factual differences between this case and Beltran-Serrano,
these differences do not negate the holding of that case: an officer owes a legal duty
-8-
No. 79480-9-I/9
to exercise reasonable care when engaging in affirmative conduct toward others,
whether they be crime victims or individuals suspected of committing crimes. As the
Supreme Court indicated in Beltran-Serrano, when “harm result[s] from the officer’s
direct contact with [a] plaintiff[], [and] not the performance of a general public duty of
policing” the public duty doctrine does not apply. Id. at 551. If the officers act, they
have a duty to act with reasonable care. Id.
Here, whether the use of lethal force breached a duty of reasonable care is a
question for the trier of fact. The Officers may ultimately convince a jury that lethal
force was the only viable option. But Beltran-Serrano establishes that the public duty
doctrine does not bar the Estate’s negligence claim.
B. Felony Defense Statutory Immunity
The Officers next contend they have complete statutory immunity under
Washington’s felony defense statute, RCW 4.24.420. Because genuine issues of
material fact exist regarding the applicability of that statutory immunity, we conclude
summary judgment was inappropriate.
RCW 4.24.420 provides:
It is a complete defense to any action for damages for personal injury or
wrongful death that the person injured or killed was engaged in the
commission of a felony at the time of the occurrence causing the injury
or death and the felony was a proximate cause of the injury or death.
RCW 4.24.420 requires proof that the person killed was engaged in the commission
of a felony at the time of her death. The Officers allege that Lyles was engaged in the
commission of a felony because her conduct constituted first degree assault with a
-9-
No. 79480-9-I/10
deadly weapon under RCW 9A.36.011(1) and attempted murder under RCW
9A.28.020(1) and (3), and RCW 9A.32. 6
Assault with a deadly weapon requires proof that a person, with the intent to
inflict great bodily harm, assaulted another with a deadly weapon. RCW 9A.36.011(1);
11 WASHINGTON PRACTICE: WASHINGTON PATTERN JURY INSTRUCTIONS: CRIMINAL 35.01,
at 480 (4th ed. 2016) (WPIC). As the Estate correctly notes, the mens rea for first
degree assault is the specific intent to inflict great bodily harm. State v. Elmi, 166
Wn.2d 209, 215, 207 P.3d 439 (2009). Attempted murder requires proof of the specific
intent to cause the death of another person. State v. Boswell, 185 Wn. App. 321, 335,
340 P.3d 971 (2014); WPIC 26.01.
To benefit from complete immunity under RCW 4.24.420, the Officers must
prove that Lyles formed the specific intent either to inflict great bodily harm or to cause
death. The Officers argue they have no burden of proving any specific mens rea. We
disagree. In Davis v. King County, No. 79696-8-I, slip op. at 9-10 (Wash. Ct. App. Feb
1, 2021), this court concluded that a defendant asserting immunity under RCW
4.24.420 must prove the party killed formed the intent to commit a felony. In Davis,
two King County Sheriff’s deputies shot and killed a woman in her home after she
allegedly pointed an unloaded gun at them. Id. at 4-5. After Davis’s estate brought a
wrongful death action, the trial court granted summary judgment for the deputies,
ruling that Davis was engaged in the commission of first degree assault when the
6
The Officers do not identify the provision of our homicide statute on which they rely to substantiate
this assertion. Chapter 9A.32 RCW includes premeditated murder, murder in the first and second
degree, and manslaughter in the first and second degree. All are felonies but each contains a different
mens rea, from premeditation and intent, to recklessness and negligence. Because the Officers
repeatedly use the word “murder,” we assume the Officers are relying on RCW 9A.32.030 (murder in
the first degree) or RCW 9A.32.050 (murder in the second degree).
- 10 -
No. 79480-9-I/11
deputies killed her and that RCW 4.24.420 barred the Davis’s claims. Id. at 6. This
court reversed, concluding that specific intent is an essential element of first degree
assault and Davis’s history of mental illness, the deputies’ conflicting testimonies
about the placement of the gun, and Davis’s dying statement that the gun was not
loaded raised a genuine issue of material fact as to whether Davis had formed the
requisite intent to commit assault. Id. at 9-10. 7
As in Davis, there is a genuine issue of material fact as to Lyles’ specific intent
to commit assault with a deadly weapon or attempted murder. A person’s diminished
capacity, due to a mental illness, may impair her ability to form the specific intent to
commit a crime. State v. Nuss, 52 Wn. App. 735, 738, 763 P.2d 1249 (1988).
Contrary to the Officers’ contention, diminished capacity is not an affirmative defense
for which a criminally charged defendant bears the burden of proof, but is merely
evidence that negates specific intent. Id. at 739. See also WPIC 18.20 (Diminished
Capacity – Defense). 8 Generally, a criminally charged defendant must present
evidence of a mental disorder and expert testimony must logically and reasonably
connect the defendant’s alleged mental condition with the asserted inability to form
the mental state required for the crime charged when the defendant seeks a
7
The Officers argue Lyles’s intent is immaterial under RCW 4.24.420, citing Estate of Lee v. City of
Spokane, 101 Wn. App. 158, 177, 2 P.3d 979 (2000). But Lee simply states “[i]t is a complete defense
to any action for damages for wrongful death that the person killed was engaged at the time in the
commission of a felony and that the felony was a proximate cause of death.” Id. Lee contains no
discussion of whether the aggressor’s mens rea should be considered when adjudicating a defendant’s
immunity under RCW 4.24.420. Generally, in cases where a legal issue is not discussed in an opinion,
the case is not controlling on a future case where the legal issue is properly raised. Berschauer/Phillips
Constr. Co. v. Seattle Sch. Dist. No. 1, 124 Wn.2d 816, 824, 881 P.2d 986 (1994). Lee does not discuss
mens rea under RCW 4.24.420 and is not controlling here.
8
Diminished capacity is treated as an affirmative defense only to the extent that the defendant carries
the burden of producing sufficient evidence of diminished capacity to put the defense in issue. State v.
Carter, 31 Wn. App. 572, 575, 643 P.2d 916 (1982).
- 11 -
No. 79480-9-I/12
diminished capacity jury instruction. State v. Atsbeha, 142 Wn.2d 904, 914, 16 P.3d
626 (2001). When a defendant presents such evidence, a court may instruct the jury
that “[e]vidence of mental illness or disorder may be taken into consideration in
determining whether the defendant had the capacity to form (fill in requisite mental
state).” WPIC 18.20. Thus, while the Estate may have the burden to produce
evidence that Lyles suffered from a mental illness that diminished her capacity to form
the requisite specific intent, the ultimate burden of proving each element of the alleged
felonies remains with the Officers.
If a jury were to find, as the Estate contends, that Lyles suffered from a mental
disorder that rendered her unable to form the mens rea of a felony, then the jury could
conclude the Officers failed to prove she was engaged in the “commission of a felony”
and they would not be entitled to statutory immunity under RCW 4.24.420.
Here, the Officers presented prima facie evidence that Lyles committed at least
felony assault. They both testified she lunged at them with a knife while making
threatening statements. Although the Officers may have no direct evidence of Lyles’s
intent, a jury may infer it from this circumstantial evidence. “A jury may infer criminal
intent from a defendant’s conduct where it is plainly indicated as a matter of logical
probability. This includes inferring or permissively presuming that a defendant intends
the natural and probable consequences of his or her acts.” State v. Bea, 162 Wn.
App. 570, 579, 254 P.3d 948 (2011) (citations omitted).
The Estate, however, presented evidence that Lyles was suffering from a
psychosis at the time of the shooting that impaired her ability to form this mens rea.
The police reports of the June 5, 2017 incident describe Lyles as disoriented,
- 12 -
No. 79480-9-I/13
delusional, experiencing hallucinations, and exhibiting impaired judgment. The
Officers testified that Lyles’s conduct swung rapidly from coherent to aggressive
without warning on June 18. Dr. Whitehill testified that Lyles had a history of
depression, post-traumatic stress disorder, adjustment disorder and an anxiety
disorder, as well as a history of decompensation and emerging psychosis.
Dr. Whitehill concluded from his review of the records that “she was in a psychotic
state and did not have the capacity to intend to assault [the Officers] when she
encountered police on June 18, 2017.”
The Estate contends the trial court erred in excluding Dr. Whitehill’s declaration.
We agree. First, evidence of Lyles’s mens rea is relevant under RCW 4.24.420. The
Officers must prove each element of the alleged felony, including intent, and evidence
of Lyles’s incapacity to form intent to commit felonious assault or attempted murder at
the time of her shooting relates directly to an element of proof under RCW 4.24.420.
Second, the testimony is admissible under Frye. The Officers contend
Dr. Whitehill’s methodology, termed a “psychological autopsy,” is not generally
accepted in Washington. But there is nothing in the record to establish that
Dr. Whitehill’s “psychological autopsy” methodology is unsound. Dr. Whitehill testified
that a psychological autopsy “is an established practice within the field of forensic
psychology to determine the mental state of someone who is already deceased.” The
Officers presented no evidence to contradict this testimony. 9
9
Other state courts have also approved of the methodology, finding no distinction between
psychological autopsies and psychiatric opinion evidence in general. See Jackson v. State, 553 So.2d
719 (Fla. Dist. Ct. App. 1989).
- 13 -
No. 79480-9-I/14
Finally, the Officers argue Dr. Whitehill’s testimony is inadmissible because he
did not treat, evaluate, or test Lyles, citing to State v. Johnson, 150 Wn. App. 663, 208
P.3d 1265 (2009). But Johnson does not support this argument. In that case, a
defendant argued fetal alcohol spectrum disorder (FASD) impaired his ability to tell
right from wrong. The trial court allowed a defense expert to testify in general as to
how FASD generally impairs a sufferer’s cognitive functioning but would not permit
the expert to testify that Johnson’s FASD precluded him from being able to tell right
from wrong. The Supreme Court affirmed because the expert testified he had no
knowledge as to how the defendant was affected by FASD and trial counsel told the
court the expert would not offer such opinions. Id. at 676-77. The Supreme Court did
not hold that an expert cannot opine on an individual’s mental state unless he has
personally examined that individual.
Fundamentally, the Officers’ arguments about Dr. Whitehill’s opinions go to the
weight, and not the admissibility, of his testimony. Such considerations are not
dispositive on admissibility under ER 702 or Frye. 10 See Pub. Util. Dist. No. 2 of Pac.
County v. Comcast of Wash. IV, Inc., 8 Wn. App. 2d 418, 446, 438 P.3d 1212 (2019)
(the credibility of expert witness testimony is best determined by the trier of fact). The
trial court thus improperly excluded Dr. Whitehill’s declaration.
The evidence of Lyles’s psychological condition on the day of her death creates
a genuine issue of material fact as to whether she had the capacity to form the
10
At oral argument, the Officers further argued that the trial court appropriately excluded Dr. Whitehill’s
testimony because, as a Ph.D. and not an M.D., he was not qualified to give such an opinion. Dr.
Whitehill’s testimony, however, was not a medical opinion, but a psychological one. Furthermore, an
attack on the academic degree held by a testifying expert assails the weight afforded the testimony,
not its admissibility. State v. Weaville, 162 Wn. App. 801, 824-25, 256 P.3d 426 (2011).
- 14 -
No. 79480-9-I/15
requisite intent to commit felony assault or attempted murder, and the trial court erred
in granting summary judgment on this issue.
C. Qualified Immunity
The Estate next argues it was entitled to summary judgment on the Officers’
affirmative defense of qualified immunity. We disagree.
In a negligence action, an officer is entitled to qualified immunity when he or
she (1) was carrying out a statutory duty, (2) according to procedures dictated to him
by statute and superiors, and (3) acted reasonably. Staats v. Brown, 139 Wn.2d 757,
778, 991 P.2d 615 (2000). The first Brown factor presents a question of law, while the
second and third factors necessarily introduce a factual inquiry into the qualified
immunity analysis under state law. See Lesley v. Dept. of Soc. & Health Servs., 83
Wn. App. 263, 275, 921 P.2d 1066 (1996) (summary judgment on qualified immunity
reversed because questions of fact existed as to whether caseworker followed proper
procedures in removing child from parental custody).
We conclude there are genuine questions of material fact as to whether Officer
Anderson followed the proper procedures in responding to Lyles’s actions and
whether both officers acted reasonably in using lethal force against her.
The Estate first contends neither officer was carrying out a statutory duty when
they responded to Lyle’s report of a burglary. This is legally incorrect. Under RCW
10.93.070, police officers have the statutory authority to enforce state criminal laws.
Responding to a 911 report of a possible crime is the execution of a police officer’s
statutory duties. The officers were in Lyles’s apartment at her invitation and with her
- 15 -
No. 79480-9-I/16
consent. As a matter of law, they were carrying out a statutory duty when they
interacted with her.
Next, the Estate argues that Officer Anderson violated SPD’s stun gun policy
by failing to carry his stun gun on patrol. This fact is undisputed. SPD policies
mandate that any officer who has been trained and certified to carry a stun gun must
do so during their shift. But that policy does not mandate that an officer use a stun
gun when attacked by a knife-wielding subject, only that the stun gun be carried with
them when on duty. If Officer Anderson had been carrying his stun gun at the time of
the shooting, there remains a question of fact as to whether its use would have been
appropriate under the circumstances. The Estate expert, D.B. Van Blaricom, testified
a stun gun would have been appropriate as a nonlethal device to subdue Lyles. Jeff
Noble, the Officers’ police practices expert, testified that Lyles was such a short
distance away from Officer Anderson that even had he deployed the stun gun, it would
have been ineffective and would have put Anderson at risk of death or serious bodily
injury. Noble testified that “a reasonable officer under the circumstances would not
have drawn or attempted to use the Taser,” because the stun gun has a low
effectiveness rate, Lyles was wearing a heavy coat, and Officer Anderson was too
close to her to ensure its efficacy
The Estate also maintains that both officers violated SPD use of force policies
by not choosing less lethal methods of subduing Lyles, a small woman at 5’ 3” and
weighing just 100 pounds. SPD’s use of force policies require that officers use only
the degree of force that is objectively reasonable, necessary, and proportional to the
threat of a subject and officers must use de-escalation tactics when circumstances
- 16 -
No. 79480-9-I/17
permit. Under Seattle Municipal Code § 3.28.115, a police officer is authorized to
discharge a firearm at another person “when necessary to . . . [d]efend himself or
another person from death or serious bodily injury.” Under that same provision of the
city code, “[a] police officer may not use a firearm unless all other reasonable
alternatives have been exhausted or would appear to a reasonable police officer to be
ineffective under the particular circumstances.”
But there are genuine issues of material fact as to whether the Officers followed
SPD use of force policies or Seattle code provisions regarding the discharge of a
firearm. Noble opined that the Officers’ use of deadly force was objectively
reasonable, necessary, and proportional to Lyles’ lethal threats. The Estate’s experts,
Maureillo and Van Blaircom, opined that the Officers did not act reasonably in using
lethal force against Lyles, and the Officers had non-lethal options available to them,
including stun guns or batons. Mauriello further testified using a firearm was also
unreasonable due to the risk of hitting Lyles’ children who were in close proximity.
The Estate contends the trial court erred in striking the declarations of Mauriello
and Van Blaricom. We agree. First, the testimony of these experts addresses the
reasonability of the Officers’ conduct in their interaction with Lyles, an issue relevant
to the application of the Officers’ qualified immunity defense.
Second, the expert opinions are admissible under both ER 702 and Frye. The
Officers argue that the Estate’s experts did not properly account for the factors
defining the reasonability of a law enforcement officer’s use of force, as laid out in
- 17 -
No. 79480-9-I/18
Graham v. Connor, 490 U.S. 386, 109 S. Ct. 1865, 104 L. Ed. 2d 443 (1989). 11 But
neither Mauriello nor Van Blaricom relied on an incorrect legal standard. Mauriello
based his opinions on the following standard:
The reasonableness of a particular use of force is based on the totality
of circumstances known by the officer at the time of the use of force and
weighs the actions of the officer against the rights of the subject, in light
of the circumstances surrounding the event. It must be judged from the
perspective of a reasonable officer on the scene, rather than with the
20/20 vision of hindsight.
As the Officers concede on appeal, “Mauriello’s declaration relies upon the Graham
standard.” They argue, however, that despite laying out this correct standard, he then
“expresses an opinion that does not account for the Graham factors and violates the
prohibition against assessing the reasonableness of force with the 20/20 vision of
hindsight.” This argument, however, does not challenge the legal standard Mauriello
applied. It is instead an attack on the credibility of his conclusions. A mere
disagreement with an expert’s conclusions, based on methods generally accepted in
the relevant community, does not render expert witness evidence inadmissible under
ER 702. Reese v. Stroh, 74 Wn. App. 550, 560, 874 P.2d 200 (1994).
As for Van Blaricom’s testimony, the Officers contend he incorrectly relied on
the standard applicable to claims of professional negligence, rather than Graham. But
Van Blaricom, like Mauriello, set out the same Graham standard for determining the
reasonableness of a police officer’s use of force. Van Blaricom, like Mauriello,
concluded that the actions of the Officers “were unreasonable.” Van Blaricom also
11
The Graham standard relates to the reasonableness of a police officer’s use of force under the Fourth
Amendment in cases arising under 42 U.S.C. § 1983. Under federal constitutional jurisprudence, the
reasonableness of an officer’s use of force is whether the officer’s actions are objectively reasonable
in light of the facts and circumstances confronting them, without regard to their underlying intent or
motivation. Graham, 490 U.S. at 397.

No. 79480-9-I/19
opined that the Officers “failed to exercise the degree of skill, care, diligence and
learning that would be expected of a reasonable police officer in the State of
Washington under the same or similar circumstances.” But this opinion was in
addition to his Graham analysis and was appropriate under the negligence standard
set out in Beltran-Serrano, 193 Wn.2d at 550. Thus, the trial court erred in striking the
Mauiello and Van Blaricom declarations.
The expert testimony here creates genuine issues of material fact as to whether
the Officers are entitled to qualified immunity and the trial court did not err in denying
the Estate’s summary judgment motion on this issue.
D. Assumption of Risk
The Estate also argues the Officers’ assumption of risk affirmative defense
should have been dismissed because there is no evidence that Lyles assumed the
risk of being killed by Officers Anderson and McNew and the trial court erred in
denying summary judgment on the issue. We disagree.
Washington courts recognize four categories of assumption of risk: express,
implied primary, implied unreasonable, and implied reasonable assumption of risk.
Gregoire v. City of Oak Harbor, 170 Wn.2d 628, 636, 244 P.3d 924 (2010). Only the
first two serve as an absolute defense; the latter two only serve as damage-reducing
factors. Id. The parties agree that only implied primary assumption of risk applies to
this case. To establish this affirmative defense, the Officers must prove that Lyles “(1)
had full subjective understanding (2) of the presence and nature of the specific risk,
and (3) voluntarily chose to encounter the risk.” Id.
- 19 -
No. 79480-9-I/20
The Officers presented evidence that Lyles had extensive history with the
police, having called for their assistance some 23 times in the recent past. There is
evidence she had previously threatened police officers in her apartment and had
acknowledged, when they drew their firearms, that she might be shot for doing so.
There is evidence she appeared to have intentionally armed herself with not one but
two knives the day the Officers responded to her 911 call and she intentionally lunged
at them, knowing the officers had their weapons drawn. A reasonable jury could find
from this evidence that Lyles subjectively understood attempting to stab armed police
officers with a knife carried a significant risk of being shot and voluntarily chose to
encounter that risk.
But the Estate has presented evidence that Lyles was in a psychotic state and
incapable of fully understanding the presence and nature of the risk posed by
threatening Officer Anderson and McNew with a knife. Lyles’s delusional statements
and bizarre behavior may indicate that she did not fully appreciate the threat posed
by the officers during that encounter. Dr. Whitehill testified Lyles’s mental illness
precluded her from voluntarily assuming the risk of her conduct.
Given this evidence, there are genuine issues of material fact and the trial court
did not err in denying summary judgment on the issue of assumption of risk.
E. Discretionary Immunity
The Estate contends the trial court erred in refusing to dismiss the City’s
affirmative defense of discretionary immunity because it does not challenge any
discretionary policy decision made by a high-level executive within the City. The City
argues the Estate’s position on appeal is new and was not the argument it advanced
- 20 -
No. 79480-9-I/21
before the trial court. We conclude the Estate did raise this argument below and the
trial court erred in refusing to dismiss the City’s affirmative defense. 12
In its answer to the third amended complaint, the City pleaded the following
affirmative defense: “Plaintiffs’ claims may be barred in whole, or in part, by
governmental immunity for discretionary, policy making, and/or judgmental functions
and decisions.” A governmental entity is entitled to immunity for “discretionary acts at
a basic policy level.” Chambers-Castanes v. King County, 100 Wn.2d 275, 282, 669
P.2d 451 (1983). “To fall within this exception, however, the discretionary act must
not only involve a basic policy determination, but must also be the product of a
considered policy decision.” Id.
The Estate moved to dismiss this defense because “Defendant has failed to
provide any evidence in support of this claim.” In response, the City argued the Estate
made various allegations about City policies and basic policy decisions and when it
tried to determine which policies the Estate was challenging, the Estate would not
identify them. In fact, the Estate represented during a discovery conference that it
was not challenging any policies or procedures. The Estate argued in reply that “[the]
City offers no evidence of high-level officials making considered policy decisions
relevant here. There is no evidence in the record to support an Evangelical/King
analysis,” citing Evangelical United Brethren Church of Adna v. State, 67 Wn.2d 246,
407 P. 2d 440 (1965) and Chambers-Castanes, 100 Wn.2d at 275. The Estate’s
briefing before the trial court and the evidence the City presented—that the Estate
12
The City indicated below that the Officers have not separately asserted a discretionary immunity
defense.
- 21 -
No. 79480-9-I/22
was not challenging any City policy decision—demonstrates that the Estate’s
argument on appeal is not new. It is indeed the same argument advanced below.
Given that the Estate has disavowed any challenge to City policies, the
discretionary immunity defense is inapplicable and should have been dismissed. 13
CONCLUSION
We reverse the summary judgment dismissal of the Estate’s claims against the
Officers because there are genuine issues of material fact on the Officers’ affirmative
defense under RCW 4.24.420. We affirm the trial court’s denial of summary judgment
as to the Officers’ qualified immunity and assumption of risks defenses. We reverse
the order denying the Estate’s motion to dismiss the City’s discretionary immunity
defense. We remand for further proceedings consistent with this opinion.
WE CONCUR:
13
This conclusion is further supported by our Supreme Court’s recent decision in Mancini v. City of
Tacoma, No. 97583, slip op. at 23 (Wash. Jan. 28, 2021), holding that the doctrine of discretionary
immunity has no bearing on cases that do not involve policy decisions made by a coordinate branch of
government.
