_______________________
A jury convicted defendant and appellant Alejandro Arauz
Lopez on three counts of sexually assaulting his daughter, D.L.,
when she was about six or seven years old.1 (Pen. Code § 288.7,
subd. (a).) On appeal, Lopez asserts that he received ineffective
assistance because his trial counsel failed to (1) object to the
testimony of the prosecution’s medical expert or present a
rebuttal expert; and (2) object to or adequately cross-examine the
prosecution’s expert on Child Sexual Abuse Accommodation
Syndrome (CSAAS). Lopez also contends that the third count of
rape is not substantially supported by the evidence. There was
no error. We affirm.
BACKGROUND
I. Prosecution’s Case
A. D.L.’s Testimony and Medical Records
At trial, D.L. testified that, in 2020 or 2021, when she was
six or seven years old, she lived with her father’s family in Los
Angeles. She shared a room with her older brother and Lopez.
The three shared a bunk bed. D.L.’s brother slept in the top bunk
and Lopez slept in the bottom bunk. D.L. moved back and forth
between the two.
One night, D.L. moved from the top bunk to the bottom
bunk because her leg hurt. After she lay down, Lopez took off his
pants. He then removed D.L.’s pants, climbed on top of her, and
touched her genitals while “shaking . . . up and down[.]” Lopez
placed D.L. on top of him and instructed her to imitate his
movements. When she refused, Lopez placed D.L. next to him,
1 The victim is referred to by her initials to protect her
privacy. (See Cal. Rules of Court, rule 8.90(b)(4).)
2
and she felt “a stick” touch her genitals. He did not stop until he
was tired, at which point he put D.L.’s pants back on. In the
morning, D.L. noticed that her pants and the bed felt wet; Lopez
told her she had urinated during the night.
D.L. testified that “something like that” happened “three or
four” times, ultimately clarifying that Lopez assaulted her three
times in as many days.2 The second and third incidents followed
the same pattern as the first. D.L. added that Lopez also
digitally penetrated her during the third incident.3
D.L. said she did not immediately report the abuse because
she feared it would get Lopez in trouble or make him angry with
her. After she moved to another state to live with her mother,
D.L. told her about the incident. Her mother took D.L. to a
pediatric clinic, where she tested positive for chlamydia.
B. Lopez’s Medical Records
After his arrest in 2023, Lopez tested positive for antibodies
consistent with a past chlamydia infection. Due to the lifespan of
the relevant antibodies, the test could not establish when he was
infected.
C. Medical Expert Testimony
Dr. Janet Arnold-Clark (Dr. Arnold-Clark), a pediatrician,
testified that chlamydia is exclusively transmitted either through
2 When asked what she meant by “the third day[,]” D.L. said
“the first time he did it, he did it again, then he did it again.”
D.L. said “it fe[lt] to [her] like it happened the next day and the
next day.”
3 A detailed summary of D.L.’s testimony on the second
incident is unnecessary, as those details are (1) duplicative of her
testimony regarding the first incident and (2) not contested on
appeal.
3
sexual contact between individuals or perinatally, meaning from
mother to child during birth. In children over the age of three,
the medical community regards a positive chlamydia test as
“diagnostic of sexual contact[.]”
D. CSAAS Expert Testimony
Dr. Jayme Jones (Dr. Jones), a clinical psychologist,
testified that CSAAS is a model that describes the behavior of
children who have been sexually abused. Specifically, Dr. Jones
testified that it is common for a child to wait before reporting
abuse. This delayed disclosure often results when the abuse
happens in secret, because the secrecy signals to the child that
they are not supposed to disclose it. It is also “very common” for
children to have trouble remembering details or timelines
surrounding incidents of abuse.
On cross-examination, Lopez’s counsel elicited testimony
that CSAAS is neither diagnostic nor predictive, but merely gives
context for the behavior of abused children. He also explored the
relative weakness of Dr. Jones’s clinical experience with CSAAS.
II. The Defense’s Case
A. Character Witnesses
Lopez called multiple character witnesses, including a
former girlfriend who described him as “a responsible, respectful
man” who worked hard to provide for his children. She trusted
Lopez to care for her children. Although she had a sexual
relationship with Lopez between 2019 and 2022, she never
contracted chlamydia.
B. Lopez’s Testimony
Lopez testified in his own defense. After he was released in
October 2023 , Lopez voluntarily took a chlamydia test, which
came back negative. Lopez denied ever experiencing symptoms
4
of, or being told that he was infected with, chlamydia. At a
bifurcated proceeding, the trial court found true the aggravating
circumstance that Lopez took advantage of a position of trust
(Cal. Rules of Court, rule 4.421, subd. (a)(11)), and sentenced him
to a total term of 25 years to life in state prison.
Lopez timely appealed. He also filed a petition for writ of
habeas corpus in case number B348099, which we consider
concurrently with this appeal.
DISCUSSION
I. Ineffective Assistance of Counsel
A criminal defendant has a constitutional right to effective
assistance of counsel. (Strickland v. Washington (1984) 466 U.S.
668, 686–688 [104 S. Ct. 2052
, 80 L. Ed. 2d. 674], (Strickland); People v. Ledesma (1987)43 Cal.3d 171, 215
.) To prevail on a claim of ineffective counsel, a defendant must demonstrate, among other things, that his counsel’s performance “fell below an objective standard of reasonableness [¶] . . . under prevailing professional norms[.]” (People v. Ledesma (2006)39 Cal.4th 641, 746
[quotingStrickland, supra,
46 U.S. at p. 688].)
“When the record on direct appeal sheds no light on why
trial counsel failed to act in the manner challenged, the
defendant must show there was no conceivable tactical purpose
for counsel’s act or omission.” (People v. Planchard (2025) 109
Cal.App.5th 157, 172 (Planchard).) Otherwise, the reviewing court “presume[s] . . . counsel’s performance fell within the wide range of professional competence and that counsel’s action or inaction can be explained as a matter of sound trial strategy.” (Ibid; see also People v. Riel (2000)22 Cal.4th 1153, 1185
(Riel) [“‘A reviewing court will not second-guess trial
counsel’s reasonable tactical decisions.’”].)
5
Lopez argues that trial counsel’s performance was deficient
in two respects. First, he argues that counsel unreasonably failed
to object to Dr. Arnold-Clark’s testimony that a positive
chlamydia test from a child over the age of three definitively
indicates sexual, rather than perinatal, transmission. But Lopez
identifies no legal basis for an objection.4 (People v. Majors
(1998) 18 Cal.4th 385, 403 [“Where ‘there was no sound legal
basis for objection, counsel’s failure to object to the admission of
the evidence cannot establish ineffective assistance.’”].)
Instead, Lopez speculates that if trial counsel had hired “an
opposing expert,” he could have “cited the declaration of . . . [that]
expert in filing a motion in limine or basic objection to the
presentation of” the prosecution’s evidence. Conjecture is not
enough to support an ineffective assistance claim.5 (People v.
Williams (1988) 44 Cal.3d 883, 933(Williams) [“A factual basis, 4 In his reply brief, Lopez argues for the first time that trial counsel should have objected to Dr. Arnold-Clark’s opinion per section 352 of the Evidence Code. “It is . . . well established that arguments may not ordinarily be raised on appeal for the first time in a reply brief.” (People v. Gonzalez (2020)57 Cal.App.5th 960
, 978.) 5 Lopez’s request for judicial notice of the contents of his habeas petition, which contains new evidence purporting to establish the availability of an opposing expert, is denied. Unlike a habeas petition, “[a]n appeal is ‘limited to the four corners of the [underlying] record on appeal[.]’” (People v. Waidla (2000)22 Cal.4th 690, 703, fn. 1
.) Where, as here, the appeal and habeas
petition are considered and decided concurrently, the petition
may not be used to augment the appellate record. (Ibid.)
6
not speculation, must be established before reversal of a
judgment may be had on grounds of ineffective assistance[.]”].)
Lopez also argues that counsel was ineffective for failing to
hire an opposing medical expert. But he does not argue that
“there was no conceivable tactical purpose for counsel’s . . .
omission.” (Planchard, supra, 109 Cal.App.5th at p. 172.) And
the record suggests a reasonable basis. Absent any evidence to
corroborate a claim of perinatal infection, counsel could
reasonably have chosen to instead focus on Lopez’s factual
defense that he could not have been the person who infected D.L.
Counsel vigorously pursued this theory, and presented
documentary and testimonial evidence to show that Lopez did not
have an active chlamydia infection and had not transmitted the
disease to his ex-girlfriend. This evidence belies Lopez’s
contention that counsel failed to dispute the presumption of
sexual transmission, and thereby effectively “closed the
possibility of an acquittal.”
Second, Lopez argues that trial counsel should have
objected to Dr. Jones’s testimony on CSAAS as cumulative and
unduly prejudicial. (Evid. Code § 352.)6 “‘[D]eciding whether to
object is inherently tactical, and the failure to object will rarely
establish ineffective assistance.’” (People v. Carrasco (2014) 59
Cal.4th 924, 985.) This is not one of those rare cases.
6 While Lopez does not cite section 352 of the Evidence Code,
his language (i.e. the testimony’s “probative value . . . was highly
outweighed by its prejudicial impact”) suggests that trial counsel
should have objected under this section. Unless stated otherwise,
further references to statutes are to the California Evidence
Code.
7
Lopez fails to demonstrate that Dr. Jones’s testimony was
either cumulative or unfairly prejudicial. He argues her
testimony “was unnecessary” because “[e]verything [Dr. Jones]
testified to could have been stated in closing argument by [t]he
[prosecution][,]” but that does not render the evidence cumulative
under section 352. (People v. Lopez (2021) 65 Cal.App.5th 484, 504 [“[e]vidence ‘may have a lower probative value if it is merely cumulative of other evidence’”] (italics added); People v. Perez (1992)2 Cal.4th 1117, 1126
[“It is elementary[] . . . that the prosecutor’s argument is not evidence[.]”].) An objection along these lines would have been meritless. (People v. Mitcham (1992)1 Cal.4th 1027, 1080
[“Counsel’s failure to make a meritless
objection does not constitute deficient performance.”].)
And while Dr. Jones’s testimony may have been prejudicial
to some extent, this is not an instance in which, on its face, the
evidence’s “probative value is substantially outweighed by the
probability that its admission will . . . create substantial danger
of undue prejudice[.]” (§ 352.) “[E]vidence is substantially more
prejudicial than probative . . . if ‘ “it poses an intolerable ‘risk to
the fairness of the proceedings or the reliability of the outcome’
[citation].” [Citation.] “The admission of relevant evidence will
not offend due process unless the evidence is so prejudicial as to
render the defendant's trial fundamentally unfair.” [Citation.]’
[Citation.]” (People v. Paniagua (2012) 209 Cal.App.4th 499,
517.) All evidence tending to prove guilt is prejudicial, and exclusion under section 352 is warranted in those situations when admission of the evidence would invoke an emotional bias against the defendant as an individual while having very little bearing on the issues before the court. (People v. Barrett (2025)17 Cal.5th 897
, 954–955.) In light of the substantial hurdles to a
8
successful section 352 objection, counsel could reasonably have
concluded the objection was not worth making. This is especially
true, because objecting might only serve to highlight the
significance of CSAAS testimony before the jury.
Alternately, Lopez urges that trial counsel’s cross-
examination of Dr. Jones was inadequate because he did not try
to elicit testimony suggesting that D.L.’s mother could have
coached her to falsely accuse Lopez. But once counsel learned the
People would not call D.L.’s mother to testify (and chose not to
call her as a defense witness), any failure to pursue this
speculative theory on cross-examination can hardly be deemed
ineffective (See Williams, supra, 44 Cal.3d at p. 933). Counsel
also reasonably abandoned a related theory along the lines that
D.L.’s mother fabricated abuse allegations to “harm” Lopez and
“win custody”. Pursuing either of these lines of inquiry could
have prompted the prosecution to call D.L.’s mother as a rebuttal
witness, and created more obstacles for the defense.
Under these circumstances, trial counsel’s decision to focus
his cross-examination of Dr. Jones on the reliability and value of
the CSAAS model, instead of an unfounded theory about the
victim’s mother, was presumptively a reasonable tactical choice.
(Planchard, supra, 109 Cal.App.5th at p. 172; Riel, supra,22 Cal.4th at p. 1185
.)
II. Sufficiency of the Evidence
Lastly, Lopez argues that insufficient evidence supports his
conviction for the third count of sexual assault. Not so.
In considering whether there is insufficient evidence
supporting a criminal conviction, we review the entire record in
the light most favorable to the judgment to determine whether it
contains substantial evidence—that is, evidence that is
9
reasonable, credible, and of solid value—such that a reasonable
trier of fact could have found the defendant guilty of the crime
beyond a reasonable doubt. (People v. Chatman (2006) 38 Cal.4th
344, 389; People v. Johnson (1980)26 Cal.3d 557
, 577–578.) We “presume in support of the judgment the existence of every fact the jury could reasonably have deduced from the evidence.” (People v. Zamudio (2008)43 Cal.4th 327, 357
.)
Here, D.L. testified at trial that there were three incidents
of assault over a three-day period when she was six or seven
years old. The third followed the same general pattern as the
first two, with the addition of digital penetration.7 This evidence
is sufficient to support Lopez’s conviction. (CALCRIM No. 1190
[“Conviction of a sexual assault crime may be based on the
testimony of a complaining witness alone.”], People v. Harlan
(1990) 222 Cal.App.3d 439, 454 [“California law does not require
corroboration of the testimony of a child sexual abuse victim[.]”].)
Lopez insists that D.L.’s testimony is insufficient because
she provided “no time frame, no specifics, etc., but rather, a very
vague statement” that the third assault was “‘the same’” as the
first two. But it is long settled that in prosecutions for child sex
abuse, “the victim’s failure to specify precise date, time, place or
circumstance” does not “render generic testimony insufficient” to
sustain a conviction. (People v. Jones (1990) 51 Cal.3d 294, 315.)
D.L. “describe[d] the kind of act or acts committed with sufficient
specificity . . . to assure that unlawful conduct . . . [of a certain]
type[]” occurred (i.e., genital contact and digital penetration);
“describe[d] the number of acts committed with sufficient
certainty to support each of the counts alleged in the information
7 Lopez does not contest the evidence supporting the first two
incidents.
10
or indictment[,]” (i.e., three times in as many days); and
“describe[d] the general time period in which these acts occurred”
(i.e., when she was six or seven years old and living with father’s
family). (Id. at p. 316.) This testimony is sufficient to support
the challenged conviction.8 (Ibid.)
