NY AG names former Diddy prosecutor to lead Cornell fraternity sexual assault investigation

New York Attorney General Letitia James has appointed Jacqueline Kelly — a former Manhattan federal prosecutor who oversaw the criminal case against Sean "Diddy" Combs — to lead the reopened criminal investigation into allegations that seven Cornell University fraternity members drugged and sexually assaulted a student over seven hours in October 2024.

On Wednesday, a day after securing a third term in office, James announced the appointment. A Cornell alumna who earned her law degree from Columbia and is now a partner at Boies Schiller Flexner, Kelly will act as outside counsel and answer directly to James's office. She will bring a team of lawyers and investigators from her firm to join in-house attorneys from the attorney general's office.

Jacqueline Kelly is a seasoned prosecutor who has overseen numerous cases from investigation through trial. With her criminal legal expertise, commitment to public service, and judicial experience, I am confident that she will lead a fair and comprehensive investigation.— Letitia James, New York Attorney General

All New Yorkers deserve a fair and thorough inquiry into the facts of this case. I look forward to lending my years of experience as a federal prosecutor to the Office of the Attorney General as we examine all available evidence.— Jacqueline Kelly, outside counsel

Kelly spent nearly a decade as a prosecutor in the Manhattan U.S. Attorney's Office, where she broke new ground as the first person to lead the civil rights unit within the criminal division. Among her areas of responsibility were civil rights offenses, voting rights violations, sex crimes, and hate crimes. Cases she oversaw included the prosecution that resulted in Combs' conviction, the New York indictment of Canadian fashion executive Peter Nygård — who was later sentenced in Canada to 11 years in prison for sexual assaults — and the matter against pain management doctor Ricardo Cruciani, who was convicted of molesting patients. She also prosecuted a dozen members of the Lucchese crime family and supervised the case against Bronx music teacher Jesus Concepcion, sentenced in 2024 to 30 years for sexually abusing five students. After leaving the U.S. Attorney's Office last year, Kelly joined Boies Schiller Flexner, where her practice centers on regulatory and criminal investigations and on representing victims of sexual assault.

At the heart of the matter is a former Cornell student referred to in court papers as Jane Doe, who claimed in a September civil lawsuit that seven Chi Phi fraternity members gave her ketamine and marijuana, and that alcohol she consumed left her unable to consent, before she was sexually assaulted across a seven-hour span on the night of October 19–20, 2024. In November 2024, she brought the incident to the attention of campus police and the university's Title IX office. NBC News reviewed records showing that the Cornell University Police Department spoke with multiple witnesses and gathered additional evidence, yet Tompkins County District Attorney Matthew Van Houten chose not to file charges after looking only at a six-page statement from Jane Doe — bypassing further statements from her or any other witnesses — and determining that it did not describe a potential crime.

The lack of arrests, followed by Jane Doe's civil lawsuit, drew intense public criticism of both the university and local law enforcement. On October 1, Governor Kathy Hochul named James as special prosecutor, citing her "lost faith" in Van Houten's ability to oversee the investigation and stating that those with an obligation to protect Jane Doe — the police among them — had "failed" her. After the lawsuit was filed, Van Houten announced he would reopen the investigation, though the Los Angeles Times reported that a lawyer for the accuser said the district attorney was preparing to take the matter to a grand jury within two weeks. James has indicated that her own investigation will require several months to complete.

According to James's office, Kelly and her team will take on the work of gathering evidence, interviewing witnesses, reviewing investigative records and reports, and analyzing the facts and applicable law. The investigation is expected to be lengthy — James has said it will take months.

The appointment does not resolve a parallel legal fight over James's own role. Lawyers for at least two of the accused fraternity members have filed petitions in separate state courts seeking to disqualify James as special prosecutor, arguing that a post she shared on X before her appointment — in which she wrote that what the young woman "has been forced to endure is horrific and unacceptable" and that she was holding her "in my heart and in my prayers" — demonstrates prejudgment and bias. James has said her investigation will be fair and fact-based, and that the remarks were made before her appointment and reflected empathy for the accuser.

At a hearing last Thursday in New York's Sullivan County, the question before Judge James R. Farrell was whether James could serve as an impartial overseer of the investigation; he declined to rule, stating that all seven accused men would have to join the request before he would make a decision. "It's not a one-defendant case," Farrell said. "It's a potential for seven. You can't have seven different proceedings."

Our Petition arose because Attorney General James publicly expressed a view concerning these allegations before she was appointed to investigate them. Changing who manages the investigation does not eliminate that concern if James continues to possess the authority to direct or override the critical prosecutorial decisions.— Andrew Miltenberg, attorney for defendant Gillio Lopes

We welcome Jacqueline Kelly's appointment and have no objection to her leading the investigative team.— Andrew Miltenberg, attorney for defendant Gillio Lopes

Though this appointment is a step in the right direction and one we welcome, James's public statements have already run afoul of the rule of law by choosing political expediency over the presumption of innocence and pre-judging guilt without examining a stitch of evidence.— Jeremy Saland, attorney for defendant Scott Kretzschmar

We applaud the decision to appoint Kelly, who we believe will do a thorough investigation. We expect that she will recognize the disparate roles of the involved parties and consider all of the appropriate charges that are available in the Penal Law.— Thomas Giuffra, attorney for Jane Doe

The case has rattled Cornell beyond the criminal sphere. Last month, the university hired former U.S. Deputy Attorney General Sally Yates to examine the school's processes for investigating sexual assault and sexual harassment, the workings of its disciplinary procedures, and how campus police handled the incident, according to the Los Angeles Times. James's office has previously used outside counsel in major investigations — in 2021, she brought in former Manhattan U.S. Attorney Joon Kim and employment lawyer Anne Clark to lead the non-criminal inquiry into sexual harassment allegations against then-Governor Andrew Cuomo, which ultimately led to his resignation.

Why it matters — The appointment of a nationally recognized sex crimes prosecutor to a case that a local DA declined to pursue — and that has already prompted a governor to override that DA — will test whether New York's intervention can deliver accountability in a campus sexual assault case that has become a flashpoint for how institutions respond to such allegations.

Sources differ on Whether AG James's pre-appointment social media post disqualifies her from serving as special prosecutor: James's post expressing empathy for the accuser constitutes prejudgment and bias that disqualifies her from leading the investigation.
