___________________________________________________
 By letter dated July 31, 2012, this court received the mandate of the Supreme
Court of the United States dated June 29, 2012, vacating the judgment filed in this case
on November 8, 2010, and remanding the case for further consideration in light of
Williams v. Illinois (2012) 567 U.S. ____ [132 S.Ct. 2221] (Williams). After considering
the decision in Williams and the parties’ responses to our invitation to address its impact
on our former opinion, we have concluded that the vacated judgment affirming the
defendant’s conviction should be reinstated, with the following additional discussion.
I. Factual and Procedural History
We summarize the pertinent facts, which are fully set out in our now-vacated
former opinion. Defendant David Suen was charged with the murder of Ron Emerick, a
security guard at the Vanguard nightclub on Hollywood Boulevard. After being escorted
from the club due to his degree of intoxication, defendant and a friend, Johnnie Nguyen,
both members of the Chinatown Boys gang, tried to convince Emerick to let them back
inside. Emerick refused and had them escorted from the premises, whereupon defendant
was heard to threaten Emerick. Defendant arranged for a friend, Milton Do, to bring him
a gun and bullets, which Do took to defendant, who was waiting outside a restaurant. Do
then drove defendant to the Vanguard club in a silver Toyota Corolla belonging to Do’s
girlfriend. There was no one else in the car. Defendant explained that they were going
back to the club “for a security guard.”
Do eventually parked the car on the street and defendant got out with the gun.
Defendant walked out of sight as he approached the front of the club. Do then heard
several gunshots. The doorman saw the shooter fire at Emerick three times, then two
more. As he ran away, the shooter fired one final time at Emerick, who died from a
gunshot wound to the chest. Defendant ran back to the car. Do and defendant drove off,
but Do crashed the car near a freeway onramp. Do and defendant ran. The police
eventually found Do and defendant under a freeway overpass. The police found a .357
Magnum pistol with six spent casings in a nearby trash can. Bullet fragments in
Emerick’s clothing and at the scene were all fired from this gun.

2
 Investigators took DNA samples from the deployed air bags of the crashed car.
Erika Jimenez, a DNA analyst with Orchid Cellmark (Cellmark), testified at trial that Do
and defendant were both possible donors of the DNA found on the passenger’s side air
bag. With respect to DNA found on the driver’s side air bag, Do was a possible donor,
but defendant was excluded as a donor.
Various employees of the Vanguard club identified defendant and Do as persons
who were escorted from the club. Defendant was identified as having made threatening
statements. The doorman who witnessed Emerick’s shooting identified defendant as the
driver of the getaway car and Do as the shooter. A witness who saw the car crash saw
two males fleeing the car. He saw only one clearly, and he identified him as Asian. He
could not identify which man was the driver and which was the passenger.
Although he was untruthful in his statement to police, Do eventually accepted a
plea agreement, agreed to testify, and stated he had not previously told the truth because
he feared gang retaliation. He testified that he was the driver of the car, defendant was
the shooter, and Nguyen was not present.
Defendant testified that Nguyen was escorted from the club due to his conduct,
and defendant merely followed. Nguyen had Do pick them up in the car of Do’s
girlfriend. Nguyen drove, Do sat in the front passenger seat, and defendant got in the
back, where he fell asleep. He woke up when he heard gunshots. Do then jumped into
the passenger seat, and Nguyen sped away and crashed the car. Do grabbed defendant
and told him to run, and then to hide, so that Do would not get caught.
Detective Robert Vargas testified in rebuttal at defendant’s trial about certain
T-Mobile cell tower location records. He stated that the various tower identification
numbers that corresponded to various cell phone calls associated with Nguyen’s cell
phone number at or near the time of the shooting indicated that those cell towers were in
the area of Koreatown. This evidence suggested that Nguyen was not in Hollywood at
the time of the shooting.
The jury convicted defendant of the first degree murder of Emerick (Pen. Code,
§ 187, subd. (a)) and of assault with a firearm on a club patron who was wounded in the

3
leg during the shooting (Pen. Code, § 245, subd. (a)(2)). The jury found “not true” the
allegations of personal firearm use by defendant.
Defendant contended on appeal, inter alia, that pursuant to Melendez-Diaz v.
Massachusetts (2009) 557 U.S. 305 (Melendez-Diaz), his constitutional right to
confrontation was violated by: (1) the testimony of a DNA analyst regarding DNA
testing by another analyst, and (2) the testimony of a police detective who explained cell
tower site records absent explanatory testimony from an employee of the cell phone
company.
We affirmed the judgment and distinguished Melendez-Diaz. With respect to the
DNA evidence, we observed that in Melendez-Diaz, the prosecutor introduced affidavits
without a witness to support them (Melendez-Diaz, supra, 557 U.S. at p. 308), whereas in
defendant’s case, a DNA analyst subject to cross-examination testified in detail about the
forensic analysis conducted by others at her company, the quality control maintained, the
procedures used, and her expert conclusions. We also drew on the conclusion in People v
Geier (2007) 41 Cal.4th 555 (Geier), and pointed out that the laboratory reports in
defendant’s case were not testimonial hearsay, but were based on direct observation of
test results and constituted “a contemporaneous recordation of observable events rather
than the documentation of past events.” (Id. at p. 605.) Finally, we noted that admission
of the DNA lab reports was consistent with the well-established principle that an expert
witness “may base an opinion on reliable hearsay, including out-of-court declarations of
other persons,” citing In re Fields (1990) 51 Cal.3d 1063, 1070, Geier, supra, 41 Cal.4th
at page 608, footnote 13, and People v. Gardeley (1996) 14 Cal.4th 605, 618.
With respect to evidence of the cell tower records, we concluded that the records
were not affidavits or other formalized testimonial materials, but rather business records,
citing Melendez-Diaz, supra, 557 U.S. at page 311, footnote 1. These records were not
testimonial even if they were not prepared in the course of equipment maintenance or
were not formally deemed a business record exception to the hearsay rule under Evidence
Code section 1271.

4
 Finally, we concluded that any error regarding admission of the DNA and cell
tower evidence was harmless beyond a reasonable doubt because: (1) defendant’s
defense was undermined by several witnesses, (2) the prosecution’s case was supported
by substantial evidence, and (3) the witnesses presenting the DNA and cell tower
evidence were subjected to cross-examination.
After the United States Supreme Court granted the writ of certiorari and remanded
the cause for further consideration in light of Williams, we invited counsel to provide
supplemental briefing. Defendant now argues that whatever uncertainty has resulted
from the Supreme Court’s 4-1-4 split in Williams, its prior decisions in Bullcoming v.
New Mexico (2011) 564 U.S. ____ [131 S.Ct. 2705] (Bullcoming) and Melendez- Diaz
are dispositive. In addition, he maintains that the application of the harmless error
standard governing federal constitutional error must be reconsidered and the judgment
reversed.
II. Summary of Pertinent Case Law
The confrontation clause of the Sixth Amendment of the United States
Constitution provides that “‘[i]n all criminal prosecutions, the accused shall enjoy the
right . . . to be confronted with the witnesses against him.’” (Crawford v. Washington
(2004) 541 U.S. 36, 42 (Crawford).) The confrontation clause has traditionally barred
“admission of testimonial statements of a witness who did not appear at trial unless he
was unavailable to testify, and the defendant had had a prior opportunity for cross-
examination.” (Crawford, at pp. 53-54.) “Under Crawford, the crucial determination
about whether the admission of an out-of-court statement violates the confrontation
clause is whether the out-of-court statement is testimonial or nontestimonial.” (Geier,
supra, 41 Cal.4th at p. 597.)
Crawford did not specify what constitutes a testimonial statement for purposes of
the confrontation clause, but offered examples of the “[v]arious formulations of this core
class of ‘testimonial’ statements,” i.e., “‘ex parte in-court testimony or its functional
equivalent—that is, material such as affidavits, custodial examinations, prior testimony
that the defendant was unable to cross-examine, or similar pretrial statements that

5
declarants would reasonably expect to be used prosecutorially,’ [citation]; ‘extrajudicial
statements . . . contained in formalized testimonial materials, such as affidavits,
depositions, prior testimony, or confessions,’ [citation]; [and] ‘statements that were made
under circumstances which would lead an objective witness reasonably to believe that the
statement would be available for use at a later trial’ [citation].” (Crawford, supra, 541
U.S. at pp. 51-52.)
In a subsequent case, the high court explained that “[s]tatements are
nontestimonial when made in the course of police interrogation under circumstances
objectively indicating that the primary purpose of the interrogation is to enable police
assistance to meet an ongoing emergency. They are testimonial when the circumstances
objectively indicate that there is no such ongoing emergency, and that the primary
purpose of the interrogation is to establish or prove past events potentially relevant to
later criminal prosecution.” (Davis v. Washington (2006) 547 U.S. 813, 822 (Davis).)
After the decision in Davis, the California Supreme Court was called upon to
determine the admissibility of a report detailing DNA testing when the evidence was
admitted by means of the testimony of a lab director who cosigned the analyst’s report.
(Geier, supra, 41 Cal.4th 555.) In Geier, the defendant was convicted of rape and murder
based in part on DNA evidence. (Id. at pp. 562, 564-565, 593-596.) The laboratory
analyst from Cellmark who performed the DNA testing did not testify at trial—a
laboratory director who cosigned the report testified instead. (Id. at pp. 593-594 & fn. 11,
596.) The laboratory director testified that, based on the test results and in her expert
opinion, the DNA extracted from the vaginal swabs matched the victim and defendant.
Through analysis of the case law subsequent to Crawford, the Geier court
recognized the difficulty of the threshold determination of whether evidence is
testimonial or nontestimonial. (Geier, supra, 41 Cal.4th at pp. 597-605.) The court
stated it had not found any analysis of the applicability of Crawford and Davis to the type
of scientific evidence at issue in Geier’s case to be entirely persuasive. (Geier, at p. 605.)
Based on its own interpretation of Crawford and Davis, Geier ultimately concluded that

6
the laboratory reports and notes were nontestimonial and therefore not inadmissible under
Crawford and Davis. (Geier, at pp. 605-607.)
Two years later, the United States Supreme Court issued its 5–4 decision in
Melendez-Diaz, where the trial court had “admitted into evidence affidavits reporting the
results of forensic analysis which showed that material seized by the police and
connected to the defendant was cocaine. The question presented [was] whether those
affidavits are ‘testimonial,’ rendering the affiants ‘witnesses’ subject to the defendant’s
right of confrontation under the Sixth Amendment.” (Melendez-Diaz, supra, 557 U.S. at
p. 307.) The court determined that, since “[t]he ‘certificates’ are functionally identical to
live, in-court testimony” and were made to provide prima facie evidence of the
composition, quality, and weight of the analyzed substance, under Crawford they were
“testimonial statements, and the analysts were ‘witnesses’ for purposes of the Sixth
Amendment.” (Melendez-Diaz, at pp. 309, 310-311.) The “testimonial” documents were
therefore not admissible, because the analysts were not subject to cross-examination and
the petitioner had no prior opportunity to cross-examine. (Id. at p. 311.)
Melendez-Diaz undermined many of the reasons given by the Geier court for
reaching its conclusion. For example, Geier stated that the lab reports were not
testimonial because they constituted “a contemporaneous recordation of observable
events rather than the documentation of past events,” in which the analyst had “recorded
her observations regarding the receipt of the DNA samples, her preparation of the
samples for analysis, and the results of that analysis as she was actually performing those
tasks.” (Geier, supra, 41 Cal.4th at pp. 605–606.) Melendez-Diaz discounted the value
of the near-contemporaneous nature of the events reported. (Melendez-Diaz, supra, 557
U.S. at pp. 315-316.) Geier also determined that the reports were not testimonial because
the analyst conducted the tests and made her report contemporaneously, “as part of her
job, not in order to incriminate defendant.” (Geier, at p. 607.) The notes and report were
“not themselves accusatory, as DNA analysis can lead to either incriminatory or
exculpatory results.” (Ibid.) Melendez-Diaz stated that scientific data are not neutral
when they are produced against a defendant, and statements in business records prepared

7
by those whose business activity “is the production of evidence for use at trial” may only
be admitted into evidence if subject to the requirements of the confrontation clause.
(Melendez Diaz, at pp. 321-322.)
In Bullcoming, the defendant’s blood sample was sent to a state lab for testing
after he was arrested for drunk driving. (Bullcoming, supra, 131 S.Ct. at p. 2709.) The
analyst recorded the results on a state form and signed the form, which included a
“‘certificate of analyst.’” (Id. at pp. 2709, 2710.) A reviewer certified that the analyst
was qualified and that established procedures had been followed. (Id. at p. 2711.) At
Bullcoming’s trial, the analyst who tested his blood sample did not testify because he had
been placed on disciplinary leave. (Id. at pp. 2711-2712.) The prosecution called another
analyst who was familiar with the lab’s testing procedures but had not signed the
certification, nor had he participated in, observed, or reviewed the analysis of
Bullcoming’s sample. (Id. at pp. 2710, 2712, 2713.)
The plurality opinion in Bullcoming explained that the surrogate analyst was an
inadequate substitute for the analyst who performed the test. Surrogate testimony by
someone who qualified as an expert regarding the machine used and the lab’s procedures
could not convey what the actual analyst knew or observed and would not expose “any
lapses or lies” by the certifying analyst. (Bullcoming, supra, 131 S.Ct. at p. 2715.) The
court stated that, if the Sixth Amendment is violated, “no substitute procedure can cure
the violation.” (Bullcoming, at p. 2716.)
Bullcoming reiterated the principle stated in Melendez-Diaz that a document
created solely for an evidentiary purpose in aid of a police investigation is testimonial.
(Bullcoming, supra, 131 S.Ct. at p. 2717.) Also, even though the analyst’s certificate was
not signed under oath, as occurred in Melendez-Diaz, the two documents were similar in
all material respects. (Bullcoming, at p. 2717.)
In Michigan v. Bryant (2011) 562 U.S. ____ [131 S.Ct. 1143] (Bryant), the
United States Supreme Court considered whether admission of a mortally wounded
victim’s statements to police officers violated the confrontation clause. (Id. at p. 1150.)
Police officers asked the victim what had happened and who had shot him. The victim

8
identified the defendant and said the shooting had occurred about 25 minutes earlier.
(Ibid.) The high court held that the primary purpose of the interrogation was to enable
law enforcement to meet an ongoing emergency. (Id. at pp. 1150, 1164.) In its
description of “‘ongoing emergency,’” the high court identified several factors that
informed the determination of the primary purpose of the questioning, such as the
formality of the encounter, and the statements and actions of both the declarant and the
interrogator. (Id. at pp. 1160-1161.) Quoting from Davis, supra, 547 U.S. at page 822,
the United States Supreme Court noted, “[W]e cannot say that a person in [the victim’s]
situation would have had a ‘primary purpose’ ‘to establish or prove past events
potentially relevant to later criminal prosecution.’” (Bryant, at p. 1165.) Under all of the
circumstances of the encounter, the court concluded the victim’s identification of the
defendant was not testimonial hearsay. (Id. at pp. 1166-1167.)
In Williams, the statements at issue were those of a prosecution expert who
testified that a DNA profile produced by an outside laboratory, Cellmark, matched a
profile produced by the state police laboratory using a sample of the petitioner’s blood.
(Williams, supra, 132 S.Ct. at p. 2227.) A plurality of four justices held in part that,
“Out-of-court statements that are related by the expert solely for the purpose of
explaining the assumptions on which that opinion rests are not offered for their truth and
thus fall outside the scope of the Confrontation Clause.” (Id. at p. 2228.) The plurality
offered a second basis for its decision, stating that, even if the report in question had been
admitted into evidence, it was not testimonial in that it was not sought for the purpose of
obtaining evidence to be used against the petitioner, who was not a suspect at the time.
(Id. at pp. 2228, 2243.) The plurality observed that “[t]he abuses that the Court has
identified as prompting the adoption of the Confrontation Clause shared the following
two characteristics: (a) they involved out-of-court statements having the primary purpose
of accusing a targeted individual of engaging in criminal conduct and (b) they involved
formalized statements such as affidavits, depositions, prior testimony, or confessions.”
(Id. at p. 2242.)

9
 Justice Thomas joined the four justices of the plurality solely in the judgment.
Justice Thomas concluded that the disclosure of Cellmark’s out-of-court statements by
means of the expert’s testimony did not violate the Confrontation Clause for the sole
reason that the expert’s testimony “lacked the requisite ‘formality and solemnity’ to be
considered ‘testimonial’ for purposes of the Confrontation Clause.” (Williams, supra,
132 S.Ct. at p. 2255 (conc. opn. of Thomas, J.).)
The remaining four justices joined in a vehement dissent authored by Justice
Kagan in which the conclusion that the expert’s testimony was not offered for its truth
was found to have no merit and was labeled a “prosecutorial dodge.” (Williams, supra,
132 S.Ct. at pp. 2265, 2268 (dis. opn. of Kagan, J.).) Because Justice Thomas also
believed that “statements introduced to explain the basis of an expert’s opinion are not
introduced for a plausible nonhearsay purpose,” the dissent asserted that “Five justices
specifically reject every aspect of [the plurality’s] reasoning and every paragraph of its
explication.” (Williams, at p. 2257 (conc. opn. of Thomas, J.); id. at p. 2265 (dis. opn. of
Kagan, J.).)
People v. Lopez (2012) 55 Cal.4th 569 (Lopez) is one of three major cases from
the California Supreme Court addressing confrontation clause issues after the Williams
decision. The others are People v. Dungo (2012) 55 Cal.4th 608 (Dungo) and People v.
Rutterschmidt (2012) 55 Cal.4th 650 (Rutterschmidt). All three cases, like Williams,
were concerned with confrontation clause issues engendered by the results of technical
reports whose contents were testified to by someone other than the person who conducted
the analysis. (See Lopez, at p. 573 [laboratory report on blood-alcohol level]; Dungo, at
p. 612 [autopsy report]; Rutterschmidt, at p. 659 [laboratory reports on testing of murder
victim’s blood samples].)
In Lopez, the court found no confrontation clause violation because the critical
portions of the report on the defendant’s blood-alcohol level “were not made with the
requisite degree of formality or solemnity to be considered testimonial.” (Lopez, supra,
55 Cal.4th at pp. 582, 584.) In Dungo, there was no confrontation clause violation
because “criminal investigation was not the primary purpose for the autopsy report’s

10
description of the condition of [the victim’s] body; it was only one of several purposes.”
(Dungo, supra, 55 Cal.4th at p. 621.) The Rutterschmidt court set forth the confrontation
clause arguments by the Attorney General and defendant but concluded only that any
error in allowing the laboratory director to testify to the results of two reports by analysts
who did not testify was harmless beyond a reasonable doubt, since the evidence of guilt
was overwhelming. (Rutterschmidt, supra, 55 Cal.4th at pp. 652, 659-661.)
Lopez summed up Williams by stating, “Although the high court has not agreed on
a definition of ‘testimonial,’ a review of [its] decisions indicates that a statement is
testimonial when two critical components are present. [¶] First, to be testimonial the out-
of-court statement must have been made with some degree of formality or solemnity.
[Citations.] The degree of formality required, however, remains a subject of dispute in
the United States Supreme Court. [Citations.] [¶] Second, all nine high court justices
agree that an out-of-court statement is testimonial only if its primary purpose pertains in
some fashion to a criminal prosecution, but they do not agree on what the statement’s
primary purpose must be.” (Lopez, supra, 55 Cal.4th at pp. 581-582.)
Justice Liu stated in his dissent to Lopez that the nine separate opinions offered by
the California Supreme Court in Lopez, Dungo, and Rutterschmidt reflected “the muddled
state of current doctrine concerning the Sixth Amendment right of criminal defendants to
confront the state’s witnesses against them.” (Lopez, supra, 55 Cal.4th at p. 590 (dis.
opn. of Liu, J.).) Justice Liu stated that Williams produced no authoritative guidance
beyond the result reached on its facts. (Lopez, at p. 590.) The majority in Dungo noted
that the complexities of the case were not easy to resolve in light of the widely divergent
views of the justices in Williams. (Dungo, supra, 55 Cal.4th at p. 618.) Justice Chin,
concurring in Dungo, stated that the split among the justices in Williams made it
“difficult to determine what to make of that decision.” (Dungo, at p. 628 (conc. opn. of
Chin, J.).) He concluded that it was necessary to decide whether there was a
confrontation clause violation under Justice Thomas’s opinion and whether there was a
confrontation clause violation under the plurality’s opinion. If there was not, then the
result would command the support of a majority of justices in the Williams decision.

11
(Dungo, at p. 629 (conc. opn. of Chin. J.); see also People v. Barba (2013) 215
Cal.App.4th 712, 733-734 (Barba) [concluding that Justice Chin’s opinion, even if not
binding precedent, was persuasive authority and a reliable indicator of how the majority
would hold].)
Several districts of the California Courts of Appeal have published decisions
applying the line of authority developed by the United States Supreme Court and the
California Supreme Court. These decisions include People v. Huynh (2012) 212
Cal.App.4th 285 (Huynh), People v. Holmes (2012) 212 Cal.App.4th 431 (Holmes),
People v. Steppe (2013) 213 Cal.App.4th 1116 (Steppe) and Barba, supra, 215
Cal.App.4th 712.
In Huynh, the defendant contended his Sixth Amendment rights were violated
when a nurse testified about a victim’s sexual assault examination conducted by another
nurse. (Huynh, supra, 212 Cal.App.4th at p. 315.) At issue were two photographs taken
during the examination of the victim, which were used by the testifying nurse to state her
independent opinion. (Id. at p. 320.) The court held that the photographs lacked the
formality and solemnity required to be testimonial. (Ibid.) In addition, the photographs
did not have a primary purpose that pertained in some way to a criminal prosecution,
since it was not known at the time of the examination if the drugged victim had been
sexually assaulted, and the photographs were not taken for the primary purpose of
accusing a targeted individual. (Id. at p. 321.) Therefore, the witness’s testimony, which
stated objective facts she gleaned from the photographs, did not give Hunyh the right to
confront and cross-examine the examining nurse. (Id. at pp. 320, 321.)
In Holmes, supra, 212 Cal.App.4th 431, the reviewing court determined that the
confrontation clause did not bar testimony by “[t]hree supervising criminalists . . . [who]
offered opinions at trial, over defense objection, based on DNA tests that they did not
personally perform. They referred to notes, DNA profiles, tables of results, typed
summary sheets, and laboratory reports that were prepared by nontestifying analysts.
None of these documents was executed under oath. None was admitted into evidence.
Each was marked for identification and most were displayed during the testimony. Each

12
of the experts reached his or her own conclusions based, at least in part, upon the data
and profiles generated by other analysts.” (Id. at p. 434.) The Holmes court reasoned
that these documents were not testimonial because, “[t]he forensic data and reports in this
case lack ‘formality.’ They are unsworn, uncertified records of objective fact. Unsworn
statements that ‘merely record objective facts’ are not sufficiently formal to be
testimonial.” (Id. at p. 438.) Holmes concluded, “It is now settled in California that a
statement is not testimonial unless both criteria [i.e., formality and primary purpose] are
met. In Lopez, the court concluded that lack of formality alone rendered the blood-
alcohol report nontestimonial regardless of its primary purpose. [Citation.]” (Holmes, at
p. 438.)
In Steppe, supra, 213 Cal.App.4th 1116, the appellate court upheld admission of a
laboratory technical reviewer’s independent opinion that the defendant’s DNA profile
matched DNA that was retrieved from certain evidence. The testifying witness reviewed
the raw data, interpreted it, concluded the victim’s DNA was on defendant’s clothing, and
offered a random match probability opinion. (Id. at pp. 1120-1121.) Steppe held: “Both
Williams and Lopez persuade us that the trial court’s overruling of defendant’s objection
was not error. There are two aspects of the technical reviewer’s testimony that
defendant’s objection could be viewed as encompassing, i.e., her reference to the raw
data and her reference to the conclusion reached by the clothing/door analyst, which was
the same as the conclusion she reached. As to the first, Lopez specifically held that a
machine printout is not subject to confrontation analysis. Here, it was never established
how the raw data was generated, or by whom. Defendant cites no authority that
testimony concerning raw data, by an expert subject to cross-examination, violates the
confrontation clause.” (Steppe, at p. 1126.) “As to the second aspect, the technical
reviewer’s reference during her testimony to the conclusion reached by the clothing/door
analyst, we note, . . . as a general matter, as both Williams and Lopez concluded, such lab
reports, containing these conclusions, lack the degree of formality and solemnity to be
considered testimonial for purposes of the confrontation clause.” (Id. at pp. 1126-1127.)

13
 In Barba, supra, 215 Cal.App.4th 712, a Cellmark laboratory director, who had
not personally done the DNA testing, testified about the results. Her duties included
“performing technical reviews of case folders created by the lab’s test analysts,
independently drawing conclusions from the test results based on her own expertise and
training, and either cosigning the reports or testifying about them in court.” (Id. at p.
718.) Barba found no confrontation clause error, stating, “We believe that a majority of
[the United States Supreme Court] would approve of an affirmance here for two reasons.
Justice Thomas would approve because DNA reports lack the solemnity and formality
required to be deemed testimonial. The plurality would approve because, at least as we
read the opinion, DNA test reports are not testimonial in part due to practical
considerations, and in part because their primary purpose is not to accuse a targeted
individual.” (Id. at p. 742.) The court added, “As for the practical considerations that
motivated the plurality in Williams, we agree that it makes no sense to exclude evidence
of DNA reports if the technicians who conducted the tests do not testify. So long as a
qualified expert who is subject to cross-examination conveys an independent opinion
about the test results, then evidence about the DNA tests themselves is admissible.”
(Ibid.)
III. The DNA Evidence
A. Defendant’s Arguments
Defendant points out that this court previously relied upon the Geier decision,
which was made unsound by the Lopez court’s recognition of the subsequent disparate
conclusions stated in Melendez-Diaz. (Lopez, supra, 55 Cal.4th at pp. 581-582.) Thus,
defendant argues, Lopez pulled “the precedential rug” from under Geier, and a new
analysis is called for. He maintains that the statements involved in this case are
testimonial under the two-part test indicated in Crawford, Melendez-Diaz, Bullcoming
and Williams, i.e., that an out-of-court statement is testimonial when made with some
degree of formality or solemnity and when its primary purpose pertains in some fashion
to a criminal prosecution. (Lopez, at p. 582.)

14
 B. DNA Testimony
At the time of trial, Erika Jimenez was a DNA analyst at Cellmark, a DNA testing
facility. She received six items for analysis: two swabs from a passenger’s air bag, two
swabs from a driver’s air bag, an oral swab from Do, and an oral swab from defendant.
She explained that Cellmark analysts work in teams. People from her team performed
the actions she described. She did not physically put the swabs into the tubes. Defense
counsel objected on hearsay and lack of foundation grounds.
Upon questioning from the court, Jimenez stated she was not present during
testing but had reviewed the entire case file and was positive that everything in “this
case” was correct. There were five members of the team. She signed the report with
another analyst. Another member inventoried the items and placed them in the tubes. An
automation team, separate from Jimenez’s “specific” team, performed “the whole DNA
process” because it is totally automated. There were three persons on this latter team,
two of whom worked on this case. Jimenez testified that only three persons touched the
samples.
Jimenez had with her the case file containing all the documents regarding the
samples in this case—documents attesting to the inventorying of the evidence through the
DNA extraction, quantification, amplification, loading of the samples onto the machine,
and the actual profiles, as well as the report and paperwork from the Los Angeles Police
Department. Jimenez reviewed all of the documentation before the report was issued and
made sure everything had been done correctly and that all of the quality assurance was
performed. Jimenez stated that the paperwork documenting the DNA extraction is
prepared when the extraction is being performed, and the same is true for the
quantification and the generation of the profiles. She had determined that her team
followed specific protocols for each step of the process. Jimenez then summarized the
standard procedure for obtaining a DNA profile. As part of the standard procedure, the
results of the analysis were put into a chart form to make it easy to read. Jimenez
testified regarding People’s exhibit 70, a chart of alleles, which was viewed by the jury
and which was part of her report.

15
 On cross-examination, Jimenez acknowledged that she had not done any of the
testing in this case, and she did not see the protocol being followed. She was testifying
about what she reviewed in someone else’s notes and had formed her opinion on what
others wrote, not on her personal knowledge. Jimenez stated that every sample that is run
in her lab and every profile obtained is run against every employee in the lab, every
employee that worked peripherally at the lab, all visitors to the lab, every DNA profile
obtained in the lab, and every other sample that has ever been obtained in the laboratory,
as well as all the samples in the same batch. There was no contamination noted in this
case.
C. No Confrontation Clause Violation
We conclude there was no confrontation clause violation with respect to the use of
the pages of the report testified to by Jimenez or their admission into evidence. We
believe the pages of Jimenez’s report were not testimonial because they lacked the
requisite degree of formality or solemnity to be considered testimonial. (Lopez, supra, 55
Cal.4th at p. 582.) There was no showing that the report, of which Jimenez used only
pages 3 and 4 in giving her testimony, was a certified or sworn document like the
documents in Melendez-Diaz and Bullcoming.
In Melendez-Diaz, “‘the certificates were sworn to before a notary . . .’ by the
testing analysts who had prepared the certificates. [Citation.] And in Bullcoming, the
laboratory analyst’s certificate regarding the result of his analysis was ‘“formalized” in a
signed document’ that expressly referred to court rules providing for the admissibility of
such certificates in court. [Citation.]” (Lopez, supra, 55 Cal.4th at pp. 584-585.) As in
Lopez, “[s]uch formality is lacking here.” (Ibid.) There is no evidence before us that the
report was “certified by the nontestifying analyst” as defendant claims. Even if the two
signatures were considered a certification, as defendant contends, the testifying witness
was one of the two signers, and, as far as can be determined, was on an equal basis with
the other.
Defendant argues that confrontation clause requirements cannot “‘readily be
evaded’” by the parties deliberately keeping a written statement informal “‘instead of

16
having the declarant sign . . . .’” (Bryant, supra, 131 S.Ct. at p. 1160.) Defendant
suggests that the jury knew the document was certified, and merely because the
prosecution chose to withhold the certification itself would make the right to
confrontation easily erasable. (Bullcoming, supra, 131 S.Ct. at p. 2717.) According to
defendant, the fact that the report was signed by “the analyst” sufficed to make it a
testimonial statement for Sixth Amendment purposes, and the existence or nonexistence
of evidence that it was sworn is of no consequence. He cites Bullcoming for the
proposition that “‘in Crawford, this Court rejected as untenable any construction of the
Confrontation Clause that would render inadmissible only sworn ex parte affidavits,
while leaving admission of formal, but unsworn statements “perfectly OK.”’”
(Bullcoming, supra, 131 S.Ct. at p. 2717.)
We believe that Bullcoming, which defendant elsewhere states is controlling in
this case, and Melendez-Diaz are distinguishable from the instant case. The forensic
laboratory report in Bullcoming certified that defendant’s blood-alcohol concentration
was well above the threshold for aggravated DWI, specifically, 0.21 grams per 100
milliliters. (Bullcoming, supra, 131 S.Ct. at pp. 2709, 2710.) This certification was made
for the purpose of proving a particular fact, and it indeed proved a particular fact that was
an element of the defendant’s crime. (Id. at pp. 2710, 2711.) Likewise in Melendez-
Diaz, quite apart from the fact that in that case there was no testifying witness at all, the
affidavit admitted into evidence stated that the material seized by the police and
connected to the defendant was cocaine—thus proving a particular fact that was also an
element of the crime. (Melendez Diaz, supra, 557 U.S. at p. 308.) Not so with DNA
analysis, which merely tests samples and shows what alleles can be seen in the samples.
The analysis results in this case were not certified and offered as proof of a specific fact
that the prosecution was required to prove and attested to by an analyst employed at a
state laboratory, as occurred in Bullcoming and Melendez-Diaz. (See Bullcoming, at p.
2710; Melendez-Diaz, at p. 308.) DNA analysis does not necessarily prove a defendant’s
guilt, and it may in fact prove his or her innocence. (See Williams, supra, 132 S.Ct. at
pp. 2228, 2244; Geier, supra, 41 Cal.4th at p. 607.)

17
 The record also fails to support defendant’s assumption that the other analyst who
signed the report was the analyst who performed the testing and the analyst who should
have been called to testify. Nor does the record show that it was “the other analyst” who
put the machine data into a chart, as defendant claims. The record also fails to show that
the nontestifying analyst prepared the report. We disagree with defendant’s assertion that
“the record leaves no doubt that the other person who signed the report, certifying it as
correct, was the ‘somebody else,’ namely the analyst who wrote the report after
performing the actual analysis.” Jimenez merely stated that she signed the report, as did
“another analyst,” after Jimenez reviewed the case file for D.R. No. 070606252 and
“Orchid case No. L.A. 070374.” Jimenez determined whether the procedures were
followed and quality control was performed. Jimenez’s testimony revealed there was no
one analyst who performed the test. She stated that she works in a team of five people.
One person inventoried the samples and placed them in tubes. The entire DNA process is
automated and performed by an automation team that is separate from her team. She
later stated that “there were three people that handled the actual samples in this case and
two people that signed the report.” She did not say whether one of these three handlers
was her cosigner on the report, and the testimony suggests that none of the three were,
which further indicates defendant is wrong in his assumption. The automation team
consists of three people, only two of whom worked on this case. The record thus does
not support defendant’s claim that there is one person who should have testified instead
of Jimenez. Unlike Bullcoming, defendant had an opportunity to cross-examine a live
witness who was part of the team that analyzed the DNA results—she was not merely an
employee of the same laboratory who was brought in as a surrogate when the expected
witness became unavailable, as occurred in Bullcoming. (Bullcoming, supra, 131 S.Ct. at
p. 2709.) We simply do not believe Jimenez can be classified as a surrogate witness.
Moreover, Jimenez’s testimony showed that the DNA profiles are actually
machine-generated data. As stated in Lopez, supra, 55 Cal.4th at page 583, “[b]ecause,
unlike a person, a machine cannot be cross-examined, here the prosecution’s introduction
into evidence of the machine-generated printouts . . . did not implicate the Sixth

18
Amendment’s right to confrontation.” Defendant points out, however, that in Bullcoming
the high court stated that the absent analyst was more than just a scrivener of machine-
generated data because he certified that the seal was unbroken, he verified the report
number correspondence, and he indicated that he had adhered to a precise protocol.
(Bullcoming, supra, 131 S.Ct. at p. 2714.) Jimenez testified that the proper protocol was
followed, and she noted that this was shown by the initials of various persons who
participated in the process along the way (not one person, as defendant seems to believe).
The fact that procedures must be followed along the way in order for a machine to
generate data, and the fact that the expert relies on others’ notations to verify that
procedures were followed does not necessarily corrupt the data that results from an
automated process. Although the alleles chart may not be machine-generated in the strict
sense, Jimenez did not say how or by whom the chart was generated. She used the
passive voice, stating, “When we report the profile, it’s put into a chart form to make it
easy to read.”
Defendant also claims that respondent is disingenuous in relying on Lopez and
Dungo in order to assert that Jimenez gave her own, independent opinion as to the DNA
results as an expert using the data in the Cellmark report. Defendant asserts that Lopez
merely mentions this in passing and it played no part in that case’s analysis, and Dungo
also did not rely on the fact that the expert witness gave his independent opinion.
Moreover, defendant states Jimenez made no such assertion and indeed stated that she did
not prepare the reports but only reviewed them, and she acknowledged that she did not do
any of the testing.
We disagree. Lopez noted that the testifying witness, John Willey, after reviewing
a laboratory report by a colleague who performed the analysis, voiced his own
conclusion, based on his “abilities as a criminal analyst,” that the blood-alcohol
concentration in the defendant’s blood was 0.09 percent. (Lopez, supra, 55 Cal.4th at p.
574.) Lopez concluded that, to the extent that certain notations could be considered
testimonial, their admission was harmless beyond a reasonable doubt in light of Willey’s
independent opinion that defendant’s blood sample contained a blood-alcohol

19
concentration of 0.09 percent. (Id. at p. 585.) Thus, we see that the value of the
testifying witness’s independent opinion is not insignificant, since it serves as evidence
on a par with the contents of a report prepared by a nontestifying scientist. In Dungo, the
members of our Supreme Court clearly did not find it insignificant that the testifying
pathologist gave only his own independent opinion of the victim’s cause of death after
reviewing the autopsy report prepared by another pathologist, since the court mentioned
this several times. (Dungo, supra, 55 Cal.4th at pp. 612, 614, 618, 622 (conc. opn. of
Werdegar, J.); id. at p. at 632, 633 (conc. opn. of Chin, J.).)
In this case, Jimenez clearly testified to her own opinion as an expert by relying on
the notes written by other team members during the inventory, extraction, quantification,
and other phases of the DNA testing for this case. She said so in court when asked by the
defense attorney, i.e., “ . . . you are relying on what somebody else wrote and forming
your opinion based on that; is that correct?” Jimenez answered, “Yes.” This is precisely
what expert witnesses do, and such testimony is proper. An expert may generally base
his or her opinion on any “matter,” personally known or made known to the expert,
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 [or her] testimony relates
. . . .” (Evid. Code, § 801, subd. (b); People v. Catlin (2001) 26 Cal.4th 81, 137
[physician may base his or her opinion in part upon the opinion of another physician]);
People v. Montiel (1993) 5 Cal.4th 877, 918.) It was not necessary for the prosecution to
assert that Jimenez had an independent opinion (see Bullcoming, supra, 131 S.Ct. at p.
2716), since she was plainly called as an expert witness. For example, when asked about
defendant’s DNA on the passenger air bag, she stated “I cannot exclude him from that
sample.” (Italics added.) She also explained the process of obtaining samples from air
bags was based on her own experience. Thus, the results of the DNA testing were used
by Jimenez as a basis for her expert opinion, and to the degree that defendant complains
that the admitted pages were testimonial, their admission was harmless beyond a
reasonable doubt.

20
 We agree with Barba, supra, 215 Cal.App.4th at page 742, that, “As for the
practical considerations that motivated the plurality in Williams, . . . it makes no sense to
exclude evidence of DNA reports if the technicians who conducted the tests do not
testify. So long as a qualified expert who is subject to cross-examination conveys an
independent opinion about the test results, then evidence about the DNA tests themselves
is admissible.” As Jimenez stated when asked if the quality of the testing ultimately
depends “on the person that’s testing it,” her reply was “the quality of the testing depends
on everybody in the laboratory working together and doing the right protocol.” In his
concurrence with the plurality opinion in Williams, Justice Breyer discusses the difficulty
of determining who might be required to testify regarding DNA test results. As he
observed, a dozen or more different laboratory experts might be required for a typical
DNA profile comparative analysis, each of whom may make “technical statements”
during the analysis that are relied upon by other experts. (Williams, supra, 132 S.Ct. at p.
2252 (conc. opn. of Breyer, J.).) In Melendez-Diaz, the Supreme Court held that in order
to satisfy the right to confrontation, not everyone “who laid hands on evidence must be
called” as a witness. (Melendez-Diaz, supra, 557 U.S. at p. 311, fn. 1.) Nothing in the
Williams decision indicates that this statement from Melendez-Diaz was in need of
clarification or that it should be rejected. In the instant case, Jimenez testified as an
expert, using the work product of a five-person team and a three-person automation team,
not all of whom were involved in this particular case. Her involvement was not far
removed, unlike the expert witness in Bullcoming. The laboratory report in this case is
closely analogous to unsworn and uncertified materials that were deemed insufficiently
formal to be testimonial in Williams, Lopez, Dungo, Holmes, Steppe and Barba.
Following and applying these decisions, we hold that the lab report is not testimonial, and
under the circumstances Jimenez described, her testimony, subject to cross-examination,
did not violate defendant’s confrontation rights.
As stated in Holmes: “The California Supreme Court has extracted two critical
components from the ‘widely divergent’ views of the United States Supreme Court
justices. [Citations.] To be ‘testimonial,’ (1) the statement must be ‘made with some

21
degree of formality or solemnity,’ and (2) its ‘primary purpose’ must ‘pertain[] in some
fashion to a criminal prosecution.’ [Citations.] [¶] . . . [¶] It is now settled in California
that a statement is not testimonial unless both criteria are met.” (Holmes, supra, 212
Cal.App.4th at pp. 437-438.) In the instant case, “[W]e need not consider the primary
purpose of [the DNA lab reports] . . . because . . . the critical portions . . . were not made
with the requisite degree of formality or solemnity to be considered testimonial
[citation].” (Lopez, supra, 55 Cal.4th at p. 582.)
IV. Cell Tower Records
A. Defendant’s Argument
In our prior opinion, we stated that the cell tower records did not involve, nor were
they themselves, affidavits or other formalized testimonial materials, but rather business
records. Defendant asserts that this court’s 2010 treatment of the issue does not survive
the more nuanced approach to the problem required by more recent authority. According
to defendant, the developments in decisional law now show that the records’
admissibility turns in part on their primary purpose. Defendant contends that our
Supreme Court’s holdings in Lopez and Dungo are not controlling on this issue, but
rather the decisions in Melendez-Diaz and its progeny.
Defendant cites Melendez-Diaz for the proposition that a report that otherwise
could be said to have been kept in the regular course of a business does not qualify as a
business record if it was calculated for use essentially in the court rather than in the
business. (Melendez-Diaz, supra, 557 U.S. at p. 321.) Defendant states that
consideration of the primary purpose has become paramount after Williams, supra, 132
S.Ct. 2221. He argues that the T-Mobile documents are testimonial not only because
they purport to certify facts in a formal-appearing manner, but also because their primary
purpose was for use at defendant’s trial. He asserts that a majority of the Williams court,
i.e., Justices Scalia, Thomas, Ginsburg, Sotomayor, and Kagan (the four-member dissent
and Justice Thomas) would agree with this conclusion. In addition, no T-Mobile witness
testified as to how the data was collected, and Detective Vargas admittedly did not know

22
how and by whom the information was prepared. Thus, the documents were testimonial
and subject to the Sixth Amendment’s confrontation guarantee.
B. Proceedings Below
After defendant testified, the prosecutor told the court that she wished to
introduce, through Detective Vargas, Nguyen’s and Mimi Duong’s1 phone records. The
records had been previously given to the defense, but the prosecutor and the detective had
not been able to obtain the cell tower sites corresponding with the phone records until
that afternoon. The defense had already stipulated to a portion of the phone records—the
subscriber information—and had introduced this information in its case-in-chief.2
The prosecutor explained that the complete records were about 4,000 pages in
length and encompassed all the cell tower sites in the state of California. She and
Detective Vargas had “pulled off the cell site records having to do with cell sites that
were on Mr. Nguyen’s phone records,” and wished to introduce only those records. The
prosecutor wanted to ask Detective Vargas on the stand to identify the physical location
of the pertinent cell tower sites. The defense argued that the records did not appear to be
complete, it was late discovery, and there was not sufficient foundation for them. The
defense also challenged the detective’s qualifications to testify as an expert with regard to
the records. After a hearing under Evidence Code section 402, the trial court allowed the
prosecutor to present Detective Vargas’s testimony.
Detective Vargas took the stand, and the prosecutor introduced People’s exhibit 82
consisting of 13 pages. The first page was a legend that assists the reader in
understanding the numbers and columns in the succeeding pages. The second page was a
copy of a letter from T-Mobile to a Detective Small of Hollywood Homicide stating that

1 Mimi Duong was Johnnie Nguyen’s girlfriend.
2 Prior to defendant’s testimony, defense counsel, during his case-in-chief, marked
two defense exhibits consisting of T-Mobile records for the same two phone numbers
contained in pages 2 and 3 of People’s exhibit 82. The defense and prosecution
stipulated that these records were “the official T-Mobile records as to who the subscriber
account name is.” Both numbers were ascribed to Mimi Duong.

23
the information regarding the subscriber of the designated number was being disclosed in
response to a search warrant. The third page was the identical letter that referred to a
different telephone number. Each letter was signed by the legal compliance agent of law
enforcement relations for T-Mobile USA. Pages 4 through 6 consisted of a call summary
for the first cell phone number. Pages 7 through 12 were a call summary for the second
cell number. These summaries showed the identifying numbers assigned to the cell tower
sites for all the calls made on the two cell phone numbers. For each call, the cell tower
site identification numbers were shown for the location where a call began and also for
where the call ended. The last page of exhibit 82, page 13, was a typed chart showing the
street address and city corresponding to the cell tower site identifications numbers.
Detective Vargas explained the meaning of the columns on the call summaries and
the use of the legend to understand the succeeding pages. He explained that he had
previously received cell tower site information with confusing or invalid identification
reference numbers. That very day he had telephoned T-Mobile and requested some
additional information. He testified that the last page, page 13 of exhibit 82, was a
modified list of cell tower locations that corresponded to the five-digit cell tower
identification numbers. The trial court overruled the defense objection to the testimony
on the bases of hearsay and lack of expertise. The prosecutor then questioned
Detective Vargas on his background and experience with cell phone records.
Detective Vargas explained that he put together page 13 by using the five-digit
reference number for the cell tower location on the 4,000-page list of cell tower locations
and then using the “control F” function on a computer to locate the address that
corresponded with the five-digit number. He and the prosecutor cut and pasted to make
the modified list of the numbers that were important for the current investigation.
Detective Vargas testified that the second phone number, which showed Mimi Duong as
the subscriber, was previously identified by other witnesses3 at trial as belonging to

3 During his testimony, defendant stated that the last four digits of Nguyen’s cell
phone number were 4038.

24
Johnnie Nguyen. The prosecutor and Detective Vargas focused on the 27th of January
from the hours of 12:30 to 3:00 a.m. Detective Vargas explained to the jury the area of
the city where the street addresses corresponding to the pertinent cell towers were
located. He gained his knowledge of these areas while working in all of them. He also
pointed to the areas on a map.
On cross-examination, Detective Vargas acknowledged that he was not trained by
T-Mobile to interpret their records, and he had never qualified as an expert in court on
T-Mobile records. He did not know “what T-Mobile did” to prepare the records he
received. He acknowledged that T-Mobile used the same cell tower site numbers for
Northern and Southern California sites, and he deduced or speculated that this was
because they only had five digits to work with. He knew that Verizon cell tower sites
covered a one-mile radius from the site but did not know the coverage for T-Mobile.
On redirect, Detective Vargas stated that a Ms. Johnson of T-Mobile explained to
him how to use the “control F” function for the five-digit identification number that
corresponded to the cell tower site address and to press “next” if he was first shown a
Northern California site. Based on witness statements and phone records and the fact that
the incident was a Southern California incident he checked only the Southern California
sites.
At sidebar, the defense objected to exhibit 82, the maps, and the entire testimony
on the basis of hearsay. The trial court admitted the testimony and exhibits over the
defense objection.
C. No Confrontation Clause Violation
Even if the cell tower site records were to be considered hearsay, we conclude that
their use by Detective Vargas did not violate defendant’s Sixth Amendment rights. “‘Not
all erroneous admissions of hearsay violate the confrontation clause. . . . Only the
admission of testimonial hearsay statements violates the confrontation clause . . . .’
[Citations.]” (People v. Loy (2011) 52 Cal.4th 46, 66.)
The records of cell tower sites generated by T-Mobile were not testimonial. They
were not sworn documents, despite defendant’s claims that the letters in exhibit 82 from

25
the T-Mobile legal compliance agent served to certify the accuracy of the information
supplied to law enforcement. The letters from the legal office state only: “This is in
response to the Search warrant, dated February 23, 2007, and served upon T-Mobile USA
on February 26, 2007. This subpoena requests customer identification/account
information and Call Detail Records from the T-Mobile USA subscriber assigned mobile
telephone number [number]. [¶] A search of our subscriber database discloses the
following information: . . .” This is followed by the subscriber’s name, account number,
date of birth, and other personal data. The letters clearly did not certify the accuracy of
the information, but merely the reason they were being provided. Therefore, the
information was not testimonial.
With respect to the primary-purpose prong, defendant argues that it is
incontestable that the T-Mobile documents were prepared to serve as evidence in
defendant’s criminal trial. Thus, the majority of justices who signed opinions in Williams
would have found them testimonial. In Justice Kagan’s dissenting opinion, defendant
points out, the justice found the statements at issue in Williams testimonial “because the
report is, in every conceivable respect, a statement meant to serve as evidence in a
potential criminal trial. And that simple fact should be sufficient to resolve the question.”
(Williams, supra, 132 S.Ct. at p. 2275 (dis. opn. of Kagan, J.).) And, unlike the autopsy
reports in Dungo, defendant argues, the T-Mobile report was introduced into evidence
and Detective Vargas described its contents in his testimony. (Dungo, supra, 55 Cal.4th
at pp. 618-619.)
The record indicates that the 4,000-page list of cell tower sites did not have as its
primary purpose the use of the information in a criminal prosecution, but rather that it
was merely what it purported to be—documents kept in the regular course of business
listing all of T-Mobile’s cell tower sites in California. And, the “regularly conducted
business activity” was not “the production of evidence for use at trial.” (Melendez-Diaz,
supra, 557 U.S. at p. 321.) Unlike the certificate in Melendez-Diaz, the cell tower list
was not “‘calculated for use essentially in the court, not in the business.’” (Ibid., citing
Palmer v. Hoffman (1943) 318 U.S. 109, 114.) The list clearly did not have the primary

26
purpose of accusing defendant of a crime. The same analysis applies to the call details
for the two phone numbers, which were prepared on February 26, 2007, upon the serving
of the subpoena. Although, unlike the autopsy reports in Dungo, portions of the T-
Mobile list were introduced into evidence, and Detective Vargas described the list’s
contents, he did not describe any conclusions in the document, which was the critical
point in Dungo. (Dungo, supra, 55 Cal.4th at pp. 618-619.) Of course, there were no
conclusions to describe, since the contents consisted of merely a list.
Detective Vargas testified that the last page of exhibit 82 was prepared by him and
the prosecutor for use at trial. This page listed the street addresses, cities, and general
area of the cell towers used by the two phone numbers in question. Thus, this page
clearly had as its primary purpose the contradiction of defendant’s testimony. This page
contained no certification, however, and Detective Vargas was subject to cross-
examination regarding his and the prosecutor’s method of preparation of this page.
Therefore, with respect to the cell tower site records, neither prong of the test was
satisfied, and there was no confrontation clause violation. (Holmes, supra, 212
Cal.App.4th p. 438 [in order to be testimonial, statements must have some degree of
formality and have a primary purpose that pertains to a criminal prosecution].)
V. Harmless Error
In any event, we conclude that, even if defendant’s right of confrontation under
the Sixth Amendment was violated because of Jimenez’s and Vargas’s testimony based
on the reports in question, any error was harmless beyond a reasonable doubt. (Chapman
v. California (1967) 386 U.S. 18, 24 (Chapman).) We note that, according to defendant,
our conclusion in the 2010 opinion—that any Sixth Amendment error was harmless
because the case against defendant was “compelling”—incorrectly inverted the Chapman
standard by placing the burden on the defendant to demonstrate harmlessness. Defendant
states that, although it was not wrong for this court to take notice of the respective
strengths of the prosecution and defense cases, the purpose of harmless error review is
not for the reviewing court to “‘become in effect a second jury to determine whether the
defendant is guilty,’” but instead to determine whether the error had any likelihood of

27
affecting the result of the trial. (Neder v. United States (1999) 527 U.S. 1, 19.)
Defendant asserts that it is not faithful to Chapman’s recognition of the fact that “[a]n
error in admitting plainly relevant evidence which possibly influenced the jury adversely
to a litigant cannot . . . be conceived of as harmless.” (Chapman, supra, 386 U.S. at pp.
23-24.)
With respect to the testimony by Jimenez and Detective Vargas, the trial court
instructed the jury members that they should consider the qualifications and believability
of any expert witness, the facts or materials upon which the opinions are based, and the
reasons for each opinion. The jury was told it was not bound by an opinion and might
disregard any opinion it found unreasonable. (CALJIC No. 2.80.) Both witnesses were
extensively cross-examined by the defense as to their personal knowledge and
involvement in obtaining the information on which their testimony was based.
We also agree with the reasoning of Barba that, even if the reports should not have
been admitted into evidence, the reports were meaningless without the testimony of
Jimenez and Detective Vargas. (See Barba, supra, 215 Cal.App.4th at p. 743.) And, if
the reports on which Jimenez and Detective Vargas relied had not been admitted into
evidence, their testimony would remain. (Ibid.)
Moreover, the jury clearly found that defendant’s testimony about Nguyen’s
involvement was not credible. Testimony from Do contradicted defendant’s story and
was apparently credited by the jury. Do testified that only he and defendant drove to the
club, and only he and defendant were in the car when it left the club, and defendant was
the passenger and shooter. The fact that the jury found “not true” the enhancements
charging defendant with use of a firearm indicates that they believed the prosecution had
not proved beyond a reasonable doubt that it was defendant who fired the gun. It may
have been the testimony of the witness who repeatedly identified defendant as the driver
of the getaway car and Do as the shooter that created reasonable doubt on this point.
Do’s girlfriend, Cindy Nguyen, testified that Do left the restaurant parking lot with
defendant in her car. Do was driving and defendant was sitting in the passenger seat.
She stated that she and several other people were passengers in defendant’s car driven by

28
Nguyen. Nguyen drove them to a karaoke bar in Koreatown. In addition, a bystander
who saw the car crash near the freeway testified that only two Asian males got out of the
car. One was in the driver’s seat and the other in the front passenger seat. Another
witness testified that he saw two light-skinned males hiding in the bushes where there
was an opening in a fence while a helicopter flew overhead, which corroborated Do’s
account.
We believe that admission of the DNA testimony by Jimenez and the cell tower
testimony by Detective Vargas had no likelihood of affecting the result of defendant’s
trial. That is to say, we believe it unlikely the jury would have acquitted defendant or
that there would have been a deadlock. Accordingly, defendant’s argument that his
conviction must be reversed because his Sixth Amendment rights were violated is
rejected.
DISPOSITION
The judgment is affirmed.
NOT TO BE PUBLISHED IN THE OFFICIAL REPORTS.
