The Cornell Case Exposes a Gap Between Ketamine’s Effects and New York’s Legal Definition of Incapacity

A Cornell student’s lawsuit alleges 7 Chi Phi fraternity brothers pressured her to take ketamine and raped her. Ketamine can leave someone appearing awake while detached from their body, surroundings and sense of time, a dissociative state clinicians consider incompatible with consent.

Developed as an anesthetic in the 1960s, ketamine blocks the NMDA receptor and dulls pain. Higher or repeated doses can intensify dissociation. People generally keep breathing on their own, though high doses can impede breathing or cause unconsciousness.

Under New York Penal Law § 130.00, the definition of “mentally incapacitated” turns on whether drugs or intoxicants were administered without the person’s consent. Voluntarily taking a drug falls outside that category, even when the resulting impairment is severe. A separate category, physical helplessness, can still apply if someone is unconscious or physically unable to communicate unwillingness.

Outside those categories, prosecutors have to prove force or a clearly expressed lack of consent. New York is among about 19 states that make this distinction for voluntary intoxication.

Jane Doe, then a 20-year-old Cornell undergraduate, alleges the assaults happened at the Chi Phi house in Ithaca over the night of Oct. 19 into Oct. 20, 2024. She says she’d never used ketamine before. Her civil complaint, filed Sept. 16, 2026, also alleges she was given marijuana and high-proof alcohol.

The defendants are Matthew Ingalls, Johnathan Newell, Winston Lee, Gillio Lopes, Diego Sarabia, Scott Norris and Scott Kretzschmar. None has been criminally charged. Lawyers for 2 of the men have denied the accusations.

Tompkins County District Attorney Matthew Van Houten initially declined charges in November 2024 after reviewing her 6-page sworn statement. He wrote that it “did not allege that she was drugged against her will or gang raped,” and characterized her account of her drug use and sexual conduct as “voluntary, conscious, and consensual.” Her lawyer rejected that characterization.

Van Houten has since said he wasn’t given the full police interview transcript. He reopened the case on Sept. 28, 2026, following the lawsuit.

Cornell expelled Matthew Ingalls and Johnathan Newell. Its Title IX process found Ingalls responsible for sexual assault; the supplied findings don’t establish the same outcome for Newell. Cornell suspended 2 others, found 2 not responsible for sexual misconduct and permanently barred the Chi Phi chapter from campus.

On Oct. 1, Gov. Kathy Hochul assigned Attorney General Letitia James as special prosecutor, saying she’d lost faith in the original investigation. Hochul is also seeking a change to what she calls New York’s “voluntary intoxication loophole.” A bill addressing it has repeatedly passed the State Senate since 2019 but has never received an Assembly vote.

“If someone is too intoxicated to consent, it should not matter whether they chose to use drugs or alcohol,” Hochul told reporters. “Voluntary intoxication is not a license for sexual assault, or gang rape, period.”
