A civil lawsuit filed in September 2026 has reignited scrutiny of an alleged gang rape involving members of Cornell University’s Chi Phi fraternity, prompting a reopened criminal investigation and intensifying debate over how the university and local authorities handled the case.
The complainant, identified only as Jane Doe, alleges she was sexually assaulted on October 19, 2024, after being pressured to consume ketamine and rendered too intoxicated to give consent. The incident reportedly took place at the Chi Phi fraternity house in Ithaca, New York. Doe’s lawsuit names seven former fraternity members, the Chi Phi fraternity, Cornell University, and affiliated organizations, alleging severe emotional and physical harm.
According to the lawsuit, Doe, then a 20-year-old undergraduate and member of the Tri Delta sorority, arrived at the fraternity house late that night visibly intoxicated after consuming approximately ten alcoholic drinks over several hours. The complaint details that she was coerced into taking ketamine and engaging in sexual acts with multiple fraternity members. Evidence cited in the suit includes a screenshot of a fraternity Snapchat group where members made references to available sexual encounters.
Following Doe’s report, Cornell University temporarily suspended the Chi Phi chapter and the implicated students. The university conducted a Title IX investigation beginning in January 2025, which reportedly resulted in expulsions and suspensions, although precise disciplinary outcomes have not been publicly detailed due to privacy rules. The fraternity chapter remains banned from campus.
Despite the university’s actions, no criminal charges were filed in 2024. Tompkins County District Attorney Matthew Van Houten justified the decision by citing inconsistencies between Doe’s initial account and the legal standards required to prove sexual assault under New York law. He noted that Doe’s first statement characterized her drug use and sexual activity as largely voluntary, and that New York law distinguishes between voluntary intoxication and mental incapacity caused by nonconsensual drugging. Van Houten emphasized that while the fraternity members’ behavior was “disgusting and morally reprehensible,” the available evidence did not meet the threshold for prosecution at that time.
The case sparked significant criticism, including from Ithaca’s mayor, Robert Cantelmo, who questioned the campus police investigation and its coordination with local law enforcement. Activists and elected officials, including Representative Alexandria Ocasio-Cortez and New York Governor Kathy Hochul, have highlighted the allegations as part of broader concerns about sexual violence and institutional responses at elite universities. Hochul has called for an independent review of Cornell’s handling of the matter.
In response to public outcry and the new civil complaint, Van Houten announced on September 28, 2026, that his office would review additional evidence and prepare to present the case before a grand jury. A senior sex-crimes prosecutor will oversee the process, incorporating testimony from Doe alongside any new information stemming from the lawsuit.
The named fraternity members have denied the allegations through their attorneys. One legal representative contended the matter had been exhaustively investigated by Cornell and that public statements lacked full context.
Doe, who ceased attending Cornell following the incident, described the experience as profoundly traumatizing and expressed ongoing struggles with recovery. The lawsuit seeks unspecified damages and a jury trial, with the plaintiff requesting anonymity due to fears of retaliation.
This case underscores the complexities involved in addressing campus sexual assault allegations and the challenges prosecutors face under existing legal frameworks. It also has reignited discussions on university policies and community safety standards related to sexual misconduct prevention and response.
