TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN

NO. 03-24-00101-CR

Nathaniel Pearson, Appellant v.

The State of Texas, Appellee

FROM THE 26TH DISTRICT COURT OF WILLIAMSON COUNTY NO. 20-0399-K26, THE HONORABLE DONNA GAYLE KING, JUDGE PRESIDING

MEMORANDUM OPINION

Appellant Nathaniel Pearson entered an open guilty plea to the third-degree felony offense of online impersonation. See Tex. Penal Code § 33.07(a). Following a punishment hearing, the trial court sentenced him to eight years’ confinement. In two issues on appeal, he contends that the trial court “prevented his defense” by denying him “the opportunity to present expert evidence about his mental health issues” and that defense counsel was ineffective for failing to designate Pearson’s psychiatrist, Dr. Robert Cusser, as an expert before the punishment hearing. We affirm the trial court’s judgment of conviction.

BACKGROUND

The State’s witnesses for the punishment hearing in January 2024 included Hutto Police Department Officer Scott Mattingly; Samantha Roy, the victim of the charged offense and Pearson’s former coworker; Cindy Gervasi, Samantha’s mother; Austin Police Department (APD) Officer George Chavez; APD Detective Shaun Donovan; and Melinda Wilkins, Pearson’s

ex-girlfriend and the victim of offenses for which charges were pending against him in Travis County. 1 The defense presented testimony from Dr. Cusser and from Pearson’s mother, Fatima Pearson, who was appointed his legal guardian in 2023, when Pearson was around twenty-three years old. The trial court took judicial notice of its case file and admitted into evidence hundreds of photographs and screenshots of harassing posts and messages made and sent by Pearson to Samantha; Melinda; and Jessilynn Kokason, another of his ex-girlfriends. Also admitted were the court order appointing Fatima as Pearson’s guardian; a certificate of medical examination (CME) completed by their family physician, Dr. Radha Mahale; and a competency evaluation authored by Dr. Maureen Burrows, who found Pearson competent to stand trial.

According to testimony from Samantha, Melinda, and the members of law enforcement, Pearson, who was twenty-three at the time of trial, created dozens of fake social media accounts—some in Samantha’s, Melinda’s, and Jessilynn’s names—on which he posted intimate, graphic, and obscene content of the three women and from which he bombarded them with vulgar and threatening messages, including threats of rape and death as well as evidence of stalking. Pearson uploaded child pornography of Melinda, directed people to her home to have sex with her, and tagged posts of pornographic videos and photographs with her address and the names of her friends and family members. Both Samantha and Melinda testified that Pearson violated protective orders that they had obtained against him, that his abusive behavior continued after he was arrested and released on bond, and that he had targeted their friends. Gervasi testified about the “horrible” psychological effects of the abuse against Samantha. Melinda testified that she would never be able to heal and that Internet searches of her name still returned results

featuring the child pornography. She also testified that Pearson was a manipulative liar, that he was “unsafe for people” and would “do this again,” and that she did not think he regretted his actions. At the hearing’s conclusion, the trial judge remarked that in her nine years on the bench, she had not seen an online-impersonation case “that was so detailed, so involved, vile, disturbing, and testing the limits of the sanity of the recipient[s] of those messages. It’s bad.”

During the plea hearing in November 2023, defense counsel requested that Dr. Cusser be allowed to testify remotely. The State, which had previously filed a motion for discovery of the defense’s expert witnesses, agreed to the remote testimony so long as counsel provided a copy of any report authored by Dr. Cusser in advance of the punishment hearing. 2 Counsel replied that he would try to get any medical records “rendered by the doctor . . . ahead of time.”

At the beginning of the punishment hearing, counsel notified the trial court that he had subpoenaed Dr. Cusser but had not received his resume or “any formal reports.” Counsel explained that he had been in contact with the legal department of Baylor Scott & White, with which Dr. Cusser was affiliated, and had learned that while Dr. Cusser was available to testify, he was “hesitant” to do so; counsel’s “best efforts to obtain any more information from him were not addressed.” Counsel “couldn’t force him or his legal department . . . to provide any more information” despite attempting to do so the day before.

Counsel added that he intended to have Dr. Cusser testify “as to diagnosis, his treatment plan, things like that.” Counsel disclaimed any interest in eliciting testimony with respect to “whether Mr. Pearson is a good or bad candidate for probation” and was focused on

2 The defense did not submit a list of its anticipated experts in advance of the hearing, and the trial court did not rule on the State’s motion for discovery of the defense’s expert witnesses.

“just establishing that [Pearson] is in treatment and he has been in treatment and why has he been in treatment.” In other words, counsel stated, “I need [Dr. Cusser] to let the [c]ourt know that he’s treating [Pearson] for some mental illnesses, and that’s relevant.”

Counsel agreed with the trial court that he was seeking to have Dr. Cusser testify only as a fact witness. While counsel noted that he might have sought to qualify Dr. Cusser as an expert had counsel received a report before the hearing, he stated that he was not calling Dr. Cusser as an expert because counsel did not know what the substance of Dr. Cusser’s expert testimony would be.

Against the State’s initial reluctance to agree to Dr. Cusser’s virtual testimony without his having submitted a report, the trial court asserted that counsel’s desired testimony did not require an expert opinion and underscored the fact that the testimony’s subject was already well known to the court:

Is that not something that’s been a core issue of this case for the at least four years that it’s now been pending, that this—[Pearson] has mental health issues, there’s a guardianship pending, he has a diagnosis? This is no secret. I’ve been told this at least a dozen times. I don’t understand what the issue is.

Ultimately, both parties assented to “limiting [Dr. Cusser’s] testimony to he’s the treating [psychiatrist], this is his diagnosis, this is the course of treatment.”

Dr. Cusser, who had not previously testified in a trial, testified about his treatment of Pearson, whom Dr. Cusser began seeing in 2020. He typically saw Pearson every three months, although “[t]here have been one or two times that it’s pushed to closer to five.” When asked for the focus of his treatment plan and what he and Pearson were “addressing,” Dr. Cusser answered only, “So I manage medications, and he’s being treated with medications.” Pearson had told Dr. Cusser that he was tolerating and benefitting from his current medication, and he had been

“stable” for around a year. Asked about “the future plan” for Pearson’s treatment, Dr. Cusser replied that the current medication regimen and Pearson’s therapy—which was overseen by a different specialist—would continue. Dr. Cusser had not noticed any problems, and Pearson had been “pretty steady” and had consistently attended their appointments. Regarding Pearson’s improvement during treatment, Dr. Cusser testified, “I’ve heard from him that he’s been more calm and levelheaded and not as irritated, and he’s been telling the truth. There was some concern about whether or not he was going to school or not, but he seems to be telling the truth as well.”
