At Fort Arthur trial, DNA from abdomen and mons swabs links to defendant; jurors told penetration must be proved beyond reasonable doubt

A Jefferson County jury heard competing accounts and forensic evidence on April 5, 2022, in the criminal trial of defendant Nir Benur, who is charged with sexual assault for allegedly penetrating a patient’s genital area with his finger during a post‑operative dressing change. State witnesses described the victim’s account, the procedures used during a same‑day forensic exam, and DNA testing; the defense argued evidence did not prove penetration and moved for a directed verdict, which the judge denied.

The case turned on both the legal meaning of “penetration” and where DNA was recovered. In jury instructions read aloud, the court told jurors the state must prove beyond a reasonable doubt that the defendant “intentionally or knowingly caused the penetration of the genital organ of Taylor Dempsey by inserting the defendant’s finger” and reiterated that “penetration is complete, however slight.”

Why it matters: The legal element the jury must resolve is not only whether contact occurred, but whether the contact rose to the statutory level of penetration. Prosecutors told jurors they had corroboration in the form of the victim’s testimony, contemporaneous notes, and DNA testing. The defense argued those facts are consistent with routine clinical care and swelling around sutures and do not establish the required insertion beyond a reasonable doubt.

Prosecutors called a registered forensic nurse and a DNA supervisor to describe the forensic exam and lab results. The nurse testified she conducted or reviewed the sexual‑assault nurse examination and the contemporaneous medical record documenting the complainant’s statements and the dressing changes. The Texas Department of Public Safety Crime Laboratory supervisor testified that Y‑STR testing on swabs from the mons (the area covered by underwear) and the abdomen produced a partial male profile that she interpreted as originating from a single male and that the profile was not found in 16,388 individuals in the comparison database; applying a 95 percent confidence interval, she said the profile was “not expected to occur more frequently than 1 in 5,471 U.S. males.” She also testified that labia and more internal swabs produced either no Y‑STR profile or no interpretable Y‑STR profiles.

Defense counsel focused on the lack of an interpretable profile from labial/internal swabs and on procedural explanations offered by the defendant. In a mid‑morning bench exchange, defense counsel moved for a directed verdict of acquittal, saying the evidence was insufficient to prove that the defendant “intentionally or knowingly penetrated her genital organ by inserting his finger.” The judge denied that motion, stating a reasonable jury question exists from the presented evidence.

The defense also emphasized the medical context of the encounter. In closing argument, defense counsel pointed to the procedure’s anatomy, the proximity of the suture line to the labia and groin, and the defendant’s explanation that dressing changes and tape application sometimes require bare hands rather than gloves. The defense suggested incidental touching or manipulation to reach sutures could account for the complainant’s sensations and for the DNA on exterior areas.

Prosecution closing argument urged jurors to credit the complainant’s testimony and corroboration, including the immediate reaction reported by the complainant’s mother after the appointment and the admitted lab report entries. Prosecutors argued that the DNA on the mons and abdomen is consistent with the pattern alleged by the victim and inconsistent with an entirely innocuous explanation.

The court accepted several exhibits into evidence during the hearing, including SANE records and the lab’s Y‑STR report. The judge instructed the jury on general principles — the presumption of innocence, burden of proof, and the requirement that the jury reach unanimous findings on the statutory elements — then recessed the case for closing arguments and jury deliberation.

What’s next: After the state and defense presented closing arguments, the judge gave the charge and sent jurors to deliberate. The transcript records the evidence heard and the judge’s instruction but does not include a verdict in the record provided here.

Notes: The record shows different witnesses used slightly different terminology when discussing “penetration”; the court instructed jurors to apply the ordinary meaning unless the statute provides otherwise. The Texas Medical Board records and the clinic’s contemporaneous SANE documentation were admitted and discussed during testimony.
