IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION ONE

THE PEOPLE,

Plaintiff and Respondent,

v.

NELSON CARLOS DELGADO,

Defendant and Appellant.

 A141714

 (San Francisco City & County

 Super. Ct. No. 218411)

Defendant Nelson Carlos Delgado appeals from his conviction of oral copulation 

of an eight-year-old girl and related crimes. He asserts the trial court wrongly excluded 

evidence regarding the lone eyewitness’s mental health and sexual history. However, 

given that the trial court allowed significant testimony on these topics, and given the 

limited nature and low probative value of the excluded evidence, the court’s evidentiary 

rulings were neither an abuse of discretion nor a violation of defendant’s constitutional 

rights. And even assuming the trial court erred, the error was harmless. We therefore 

affirm. 

BACKGROUND

Events at Victoria Park

In May 2012, an eight-year-old girl with Down’s Syndrome, Jane Doe, went to 

Victoria Park in San Francisco with her mother and siblings. At some point, Doe went 

off to use the bathroom and Doe’s mother lost sight of her for a few minutes. 

Maria K. and her then-boyfriend Joseph A. were also at Victoria Park. They were 

homeless at the time and park regulars. Maria, like Doe, went to use the park’s 
2

bathroom. She entered the men’s bathroom because the women’s one was occupied.

Once inside, Maria saw defendant in a stall facing the toilet. She also saw a little girl, 

facing defendant, with her back toward the toilet. Defendant was holding the young girl 

by the head or hair and his penis was in her mouth. The little girl was gagging. Maria

was later able to identify the girl as Doe. 

Maria left the bathroom, called Joseph for help, and told him what she had seen. 

Then, as Joseph tells it, Joseph confronted defendant and asked what he was doing. 

Defendant said he was cleaning the bathrooms. Joseph then saw a little girl running 

away. Defendant fled the park as a posse Joseph had roused attacked and pursued him. 

A man ran up to Doe’s mother and told her about the molestation. The mother 

found Doe in the playground. She asked Doe if she had been touched. Doe did not 

answer, but her eyes filled up with tears. Doe seemed scared, and her mother observed 

an unusual red rash around Doe’s lips. 

The next day, Joseph and Maria were again at the park and saw defendant. Joseph

summoned police, who came and arrested defendant. 

Doe later spoke with forensic interviewer Gloria Samayoa. Doe did not answer 

most of the questions. At trial, Samayoa offered no opinion about whether Doe’s 

responses were consistent or inconsistent with being a molest victim. 

An information charged defendant with oral copulation of a child 10 years old or 

younger by an adult (Pen. Code, § 288.7, subd. (b); count 1),1aggravated sexual assault

of a person under 14 by one more than seven years older (§ 269, subd. (a)(4); count 2), 

forcible lewd act upon a child under 14 (§ 288, subd. (b)(1); count 3), possession of a 

controlled substance (Health & Saf. Code, § 11377, subd. (a); count 4), and possession of 

drug paraphernalia (former Health & Saf. Code, § 11364.1, subd. (a); count 5).

Defendant pleaded guilty to count 5. The other counts proceeded to a jury trial.

Impeachment of Maria K.

Maria was the only eyewitness to the molestation. Maria, however, had mental 

health troubles and had been sexually abused herself as a child. Her believability became 

a central issue before and during trial.

Defendant subpoenaed Maria’s mental health records. A report from July 19, 

2011, states Maria suffered from depression, anger, and mood swings. It relates Maria’s

assertion that she “ ‘hear[d] voices and s[aw] a black shadow following me’ ” and that 

she did not “ ‘want to go around people.’ ” It says Maria had reported some auditory and 

visual hallucinations for years, or “since she was little,” but was not then able to afford 

treatment. The report concluded Maria was suffering from schizophrenia, schizoaffective 

disorder and bipolar affective disorder. 

A report from August 2, 2011, states Maria felt her new medicine was working 

and that the auditory hallucinations had abated and the shadows had disappeared. 

According to the report, Maria said she was feeling calmer and was able to sleep. The 

report says Maria was then not feeling depressed, angry or anxious and that her thinking 

was clear with no delusions, distortions or paranoia. 

A report dated September 22, 2011, describes a brief relapse when Maria stopped 

taking her medication for three days. Off the medication, her acute symptoms started 

again but they abated upon resuming her medication. According to the report, she was 

then thinking clearly with no distortions, delusions or paranoia. She was not depressed or 

euphoric, and was appropriate to situation, content, calm, pleasant, and cooperative. 

Finally, a March 13, 2012 report relates another relapse coinciding with Maria

stopping one of her medications. Her thinking was characterized as “paranoid, 

delusional, hallucinating.” She was instructed to restart the medication she had stopped. 

In addition to these mental health reports, defendant obtained documents showing 

Maria was arrested for prostitution and suffered a conviction in 1992 for lewd conduct. 

Defendant retained forensic psychologist Dr. Larry Wornian to review all these 

records. 
4

Before trial began, on June 25, 2013, the prosecution filed a motion in limine to 

exclude evidence regarding Maria’s mental health and sexual history as irrelevant and 

harassing. In particular, the prosecution sought to exclude: (1) Dr. Wornian’s likely 

testimony concerning Maria’s proclivities based on her mental health records or criminal 

history, (2) any evidence of mental health troubles or criminality not within the weeks or 

months surrounding Maria witnessing the crime, (3) Maria’s involuntary confinement in 

a psychiatric institution in October 2012 after she broke up with her then-boyfriend upon 

discovering he was transgender, (4) any expert testimony regarding Maria’s credibility 

generally and (5) Maria’s prior misdemeanors and arrests. 

Ruling on the motion, the trial court limited testimony about Maria’s mental health 

to allow only information regarding her ability to perceive, recollect, and explain what 

she saw. The court refused to allow evidence of hallucinations dating from more than six 

months before or after the alleged crime, specifically before September 2011 or after 

October 12, 2012. 

Giving more specific guidance, the trial court excluded evidence of Maria’s

psychiatric hospitalization related to her breakup with her transgender boyfriend. It 

further precluded inquiry into the sexual orientation or gender of Maria or the former 

boyfriend. Further, the trial court excluded evidence concerning Maria’s 1992 arrest for 

prostitution and conviction for lewd conduct, as well as all other prior misdemeanors and 

arrests. It also excluded evidence that Maria previously worked as a stripper. 

The trial court held an Evidence Code section 402 hearing concerning 

Dr. Wornian’s testimony. At the hearing, Dr. Wornian said that the “things that [Maria]

sees . . . are inherently colored by her history.” He believes “her perception of what’s 

going on right now . . . draws inherently on her memories of what had happened to her in 

the past.” Dr. Wornian questioned Maria’s credibility given her medical records, her 

being molested and raped as a child, her past sexual related arrest and convictions, her 

past job as a stripper, her hallucinations and her psychiatric hospitalization related to her 

breakup with her transgender boyfriend. He believed that her sexual background, 

combined with her mental health issues, “have served to shape her understanding of the 
5

world so that she sees things perhaps in an overly sexualized fashion.” He asserted 

having “significant concerns . . . in terms of her reliability as a historian, whether she is 

given inherently to misconstruing what is going on in the world around her, how good a 

reader of what happens in her world, what happens in herself . . . .” 

At the Evidence Code section 402 hearing, as the parties and the trial court 

discussed the impact of Dr. Wornian’s testimony, defense counsel argued Maria had been 

prone to visual hallucinations, stating in September 2010, Maria reported “men were 

following her, men in black, shadows were following her and things of that nature.” 

However, counsel appeared to be referring to the July 2011 report already discussed, as 

there is no 2010 report in the record. The court believed such evidence was irrelevant 

and said the documented hallucinations “relate to her. There’s not one record that I’ve 

been pointed to where she has reported something occurring to other people. It’s all 

about her. And in this particular case, it’s nothing about her.”

As the Evidence Code section 402 hearing ended, the trial court maintained its 

prior limitations, but decided to allow evidence showing Maria had been the victim of 

child molestation herself, saying that “our past experiences always color how we perceive 

things, I think the fact that Ms. Maria was a victim of child molestation is relevant, but I 

think the arrest, the police report, the—all that stuff is not relevant.”

Largely within the parameters set by the trial court, Maria was questioned about 

her mental health and Dr. Wornian offered testimony on her ability to perceive. 

Maria explained her mental health issues started in 2007 with depression, after she 

got laid off from her job as a nanny. As she conceded on cross-examination, Maria then 

began hearing voices, more precisely somebody calling her name. When asked if she had 

ever heard a voice telling her that she was seeing a child molest, a rape or any sort of 

sexual things, she answered no.

Maria testified she tried different medications to control her mental problems. She 

also testified that on May 12 and 13, 2012—the days surrounding the assault on Doe—

she was on medication and it was then effective at preventing hallucinations.
6

Although Maria testified she has heard voices, on cross-examination she denied

“suffer[ing] from seeing things that aren’t there.” Responding to defense counsel’s 

follow up questions, she answered she did not remember whether she had ever told 

doctors that she had seen shadows following her or men in black following her. Maria

also denied hearing voices telling her to kill herself or that she stopped taking medication 

because she was getting too many bad messages from her television. 

Dr. Wornian testified about the nature of Maria’s mental health conditions, the 

symptoms she suffered, and the medicine she used. Dr. Wornian based his testimony on 

Maria’s medical reports he was able to review. Because of the limitations imposed by the 

court, Dr. Wornian could only talk about reports dating from September 2011 to October 

12, 2012. Therefore, he did not talk about the July or August 2011 reports. He said, on 

direct examination, that the September 22, 2011 report indicated “the symptoms that 

[Maria] had originally presented with were getting worse.” Wornian later admitted this 

report states Maria was then, when medicated, thinking clearly, with no distortions, no 

delusions, no paranoia, not feeling depressed, appropriate to situation, content, calm, 

pleasant and cooperative. 

Dr. Wornian explained to the jury and the court that some symptoms related to 

schizophrenia may be auditory and visual hallucinations or delusions. He then talked 

about Maria’s March 13, 2012, psychiatric report. The report indicated she was having 

paranoid and delusional thoughts and hallucinations. Dr. Wornian thought both auditory 

or visual hallucinations were possible, even though the report did not specify which sort 

Maria was having. 

Next, Dr. Wornian referenced other mental health records from a different care 

provider. He described a December 2011 report showing Maria being generally 

maintained by her medications but still experiencing some auditory hallucinations and 

paranoid thoughts. He also described an August 2012 report showing Maria again 

stopped taking medications and experienced auditory hallucinations. 

Dr. Wornian admitted Maria appears to be motivated to seek treatment. He agreed 

with the prosecution’s assertion that “from the records, you see that when [Maria]’s 
7

having troubles she goes to the doctor” and that “there are no records of her going to the 

doctor in April, May or June” 2012. Dr. Wornian said “she seemed to have been doing 

reasonably well during that period of time.” 

Dr. Wornian also testified Maria was sexually abused several times as a child by 

different family members and opined this might affect her perceptions. He explained 

how victims of such sexual abuses do not “see[] the world the same way”; they see 

through glasses that distort the world into an “inappropriately sexualized” and 

“threatening place.” These victims can see “things that aren’t quite there.” Dr. Wornian 

said that “the accuracy of her being able to see what’s in front of her eyes, . . . when you 

start adding the issues around the delusions, the hallucinations, . . . you begin to realize . . 

. and particularly in terms of sexual issues . . . she may believe what she’s actually seeing 

but in terms of what you and I would see, it’s like, huh, how did you come up with that?

I just don’t see it.” Dr. Wornian was concerned evidence Maria had possibly witnessed 

other sexual activity at the park—sex occurring in bathrooms, a threat of rape, and 

concern (after the incident with Doe) for the possibility that another man might be 

molesting children—reflected a sexual preoccupation. However, when questioned by the 

prosecution, Dr. Wornian admitted there were no medical records showing her claiming 

sexual trauma or abuse or over-sexualizing her interactions. 

A jury found defendant guilty of counts 1–4. He was sentenced to 15 years to life

and timely appealed. 

DISCUSSION

Defendant contends the trial court prejudicially abused its discretion and violated 

his constitutional rights by excluding evidence he sought to introduce to impeach Maria. 

According to defendant, “admission of all evidence pertaining to her mental and sexrelated legal problems was critical to ensure a fair trial.” The limited evidence presented 

on these subjects, asserts defendant, was insufficient. The particular items defendant 

maintains the trial court wrongfully excluded are: Maria’s 1992 arrest for prostitution 

and conviction for lewd conduct, her psychiatric detention after she broke up with her 
8

boyfriend upon discovering he was transgender, and her possible visual hallucination in 

2010/2011 when men in black were supposedly following her. 

There is no question that Maria’s capacity and credibility were extremely 

important since she was the only eyewitness to the crime. “ ‘ “The capacity of a witness 

to observe, recollect and narrate an occurrence is a proper subject of inquiry on crossexamination. If as a result of a mental condition such capacity has been substantially 

diminished, evidence of that condition before, at and after the occurrence . . . is ordinarily 

admissible for use by the trier in passing on the credibility of the witness.” [Citations.]’ 

[Citation.]” (Farrell L. v. Superior Court (1988) 203 Cal.App.3d 521, 527–528.) 

Indeed, the right to challenge a witness’s capacity to perceive is secured by the 

Sixth Amendment. “ ‘ “[T]he right of confrontation and cross-examination is an essential 

and fundamental requirement for the kind of fair trial which is this country’s

constitutional goal.” ’ ” (People v. Wilson (2008) 44 Cal.4th 758, 793.) Yet, the 

confrontation right is not absolute. (Id. at pp. 793–794.) “ ‘Within the confines of the 

confrontation clause, the trial court retains wide latitude in restricting cross-examination 

that is repetitive, prejudicial, confusing of the issues, or of marginal relevance.’ ” 

(People v. Chatman (2006) 38 Cal.4th 344, 372.)

Evidence Code section 352 provides: “The court in its discretion may exclude 

evidence if its probative value is substantially outweighed by the probability that its 

admission will (a) necessitate undue consumption of time or (b) create substantial danger 

of undue prejudice, of confusing the issues, or of misleading the jury.” This section is 

generally compatible with the confrontation right. (People v. Gutierrez (2009) 45 Cal.4th 

789, 807–808.) Thus, the exclusion of evidence under Evidence Code section 352, in a 

way that does not produce a significantly different impression of witnesses credibility, is 

also proper under the Sixth Amendment. (People v. Chatman, supra, 38 Cal.4th at 

p. 372; People v. Brown (2003) 31 Cal.4th 518, 545–546; People v. Bradley (2012) 

208 Cal.App.4th 64, 88.)

We review a trial court’s evidentiary ruling under Evidence Code section 352 for 

abuse of discretion (People v. Holloway (2004) 33 Cal.4th 96, 134), reversing only if the 
9

court’s ruling was “ ‘ “arbitrary, capricious or patently absurd” ’ ” (People v. Suff (2014) 

58 Cal.4th 1013, 1066). If we determine the court properly exercised its discretion, there 

is, in turn, generally no constitutional violation. (People v. Espinoza (2002) 

95 Cal.App.4th 1287, 1312.) 

1992 Arrest and Conviction

The trial court did not abuse its discretion in excluding the evidence of Maria’s 

1992 arrest for prostitution and conviction for lewd conduct. These events—occurring 

some 20 years before Maria witnessed the incident involving Doe—are too remote in 

time and of virtually no relevance to Maria’s veracity and accuracy of her perceptions on 

the day of the crime. 

It is well established that “ ‘[r]emoteness’ or ‘staleness’ of prior conduct is an 

appropriate factor to consider in a[n Evidence Code] section 352 analysis.” (People v. 

Harris (1998) 60 Cal.App.4th 727, 739.) While “[t]here is no consensus among courts as 

to how remote a conviction must be before it is too remote . . . a conviction that is 20 

years old . . . certainly meets any reasonable threshold test of remoteness.” (People v. 

Burns (1987) 189 Cal.App.3d 734, 738.) Further, Maria’s 1992 arrest for prostitution and 

conviction for lewd conduct did not relate to her honesty or veracity. (See People v. 

Edwards (2013) 57 Cal.4th 658, 722 [“ ‘When determining whether to admit a prior 

conviction for impeachment purposes, the court should consider, among other factors, 

whether it reflects on the witness’s honesty or veracity [and] whether it is near or remote 

in time . . . .’ ”].) Indeed, in People v. Phillips (1985) 41 Cal.3d 29, 49–51, “the Supreme 

Court affirmed the exclusion of evidence regarding a witness’s involvement in 

prostitution, noting that such evidence was degrading and had an obvious potential for 

embarrassing or unfairly discrediting the witness.” (People v. Hayes (1992) 

3 Cal.App.4th 1238, 1248.) 

To the extent defendant contends Maria’s sex-related conduct 20 years ago is 

evidence she was likely to view Doe and defendant’s “interaction” through a “sexual” 

lens, it was only marginally relevant at best. Moreover, defendant was able to present far 

more current evidence in support of that theory from Dr. Wornian and other witnesses. 
10

Thus, the trial court’s decision to limit the number of incidents that might show Maria’s 

possible hyper-sexualization of events was well within its discretion. 

In any case, because numerous other, more salient data points as to Maria’s 

possible perception issues were provided to the jury, the jury’s impression of Maria was 

not compromised and any error in excluding the 1992 conduct was harmless. (People v. 

Sedillo (2015) 235 Cal.App.4th 1037, 1065 [no reversal unless “it is not reasonably 

probable the result at trial would have been different”], citing People v. Watson (1956) 

46 Cal.2d 818, 836.) 

2012 Hospitalization 

On October 19, 2012, about five months after the incident involving Doe, an 

involuntary psychiatric hold was placed on Maria. The hospitalization occurred after she 

broke up with her boyfriend upon discovering he was transgender. Appellant believes 

Maria should have known the boyfriend was a transsexual because they had been in a 

long-term relationship. Dr. Wornian testified at the Evidence Code section 402 hearing 

that this lapse indicated she is “not a reliable reader of interpersonal cues.” 

But Maria’s asserted difficulty in perceiving Joseph’s gender is, again, of only 

marginal relevance to whether she accurately observed a child molestation involving oral 

copulation. Furthermore, evidence concerning a witness’s own sexual preferences and 

orientation is not admissible to impeach credibility, except if used to prove bias, interest 

or motive of a witness. (People v. Rowland (1968) 262 Cal.App.2d 790, 796; People v. 

Peters (1972) 23 Cal.App.3d 522, 533.) Thus, having a mini-trial on the question of the 

boyfriend’s gender and Maria’s perception of it could have reasonably been viewed as an 

undue waste of time under Evidence Code section 352. Again, there was no abuse of 

discretion in excluding this evidence, and even if there were, it was harmless given all the 

other evidence presented to impeach Maria.

Supposed Visual Hallucination in 2010

Turning to Maria’s supposed 2010 visual hallucination, we first observe the 

existence of such a hallucination is suspect at best. The medical records before us and 

referenced in the trial court disclose no 2010 incident, and no one testified to such an 
11

incident. The only hint of such a hallucination appears in defense counsel’s remarks at 

the Evidence Code section 402 hearing while arguing there were serious questions about 

Maria’s ability to perceive reality. Defense counsel stated: “[S]he in September of 2010 

said that men were following her, men in black, shadows were following her and things 

of that nature. She was having visual hallucinations.” Looking at the psychiatric reports 

in the appellate record, however, they only mention an incident the next year, in July 

2011, during which Maria said she was “ ‘hear[ing] voices and see[ing] a black shadow 

following [her].’ ” And even though the July 2011 shadow incident was outside the oneyear window the trial court imposed, Maria was asked at trial whether she had reported to 

her doctors seeing shadows and men in black, and she responded she could not 

remember. Thus, it appears defendant may have had an opportunity to inquire about the 

very hallucination he claims he was precluded from presenting.

In any event, the trial court’s one-year limit on mental health incidents, as applied 

to the facts of this case, was not an abuse of discretion. The crucial question was Maria’s 

ability to perceive reality in May 2012. That Maria may have suffered a paranoid 

delusion in 2010 has some relevance to this crucial question, but it is of only limited

value. Moreover, it would have been cumulative evidence in light of all the evidence 

presented that Maria suffered delusions within the one-year time frame—in December 

2011, March 2012, and August 2012, both before and after she witnessed Doe’s 

molestation. Thus, the pattern was well established: Maria, following her own 

molestation as a child, had a history of “delusions” on occasions when she stopped taking 

medication, but was otherwise well managed on her medications. Adding one more 

supposed delusional incident in 2010 would not have changed the picture for the jury in 

any meaningful way. The incident was purely “cumulative” and did not open any “new 

avenues for impeachment.” (Gonzalez v. Wong (9th Cir. 2011) 667 F.3d 965, 984; see 

also People v. Gurule (2002) 28 Cal.4th 557, 595 [not every shred of witness’s 

psychiatric history must come in].)

Finally, Maria’s supposed perception of shadows or belief that men in black were 

following her reflect a generic paranoia, not a person who invents whole cloth stories 
12

about others, let alone stories about criminal activity. “It is a fact of modern life that 

many people experience emotional problems, undergo therapy, and take medications for 

their conditions.” (People v. Anderson (2001) 25 Cal.4th 543, 579.) However, “ ‘[a] 

person’s credibility is not in question merely because he or she is receiving treatment for 

a mental health problem.’ ” (Ibid., quoting People v. Pack (1988) 201 Cal.App.3d 679, 

686.)

We therefore find no abuse of discretion and further conclude any error in 

excluding the supposed 2010 hallucination was harmless.

Due Process Claims

While defendant alludes, in passing in his opening brief, to his Fifth and 

Fourteenth Amendment rights to due process and a fair trial, he does not provide any 

constitutional analysis. He therefore has forfeited any such issues. (People v. Redd

(2010) 48 Cal.4th 691, 730.) In any case, having concluded the trial court acted well 

within its discretion under Evidence Code section 352, we discern no constitutional 

issues here. (See People v. Espinoza, supra, 95 Cal.App.4th at p. 1312.) 

DISPOSITION

The judgment is affirmed.
