University of Oklahoma Police Chief Derek Fuller emailed every student organization president and adviser on Tuesday, Oct. 13, warning of hazing, impaired driving, drug use and sexual misconduct across campus.

The letter, reported by the OU Daily, went out the day before the university resolved a hazing case against Sigma Nu on Wednesday, Oct. 14. A second fraternity, Pi Kappa Alpha, was found responsible for hazing Sept. 16. As we reported Thursday, both organizations received sanctions this semester.

Fuller's message reached beyond Greek life. He addressed leaders of all registered student organizations and said the university had received "multiple reports of suspected hazing this semester."

"These concerns warrant immediate attention," Fuller wrote.

Liquor and drug referrals spike

OU's Annual Security and Fire Safety Report showed disciplinary referrals for liquor law violations jumped from 202 in 2024 to 355 in 2025. Drug law violation referrals nearly doubled over the same period, rising from 34 to 67.

The university's own biennial review of its Alcohol and Other Drug Program flagged "resource constraints" as a weakness, the OU Daily reported. The evaluation warned that limited resources "may hinder the implementation of certain prevention initiatives."

OU recorded four on-campus hazing incidents and 30 non-campus hazing incidents in 2025, according to the same report.

Fuller warns of criminal exposure

Fuller reminded student leaders that hazing is illegal under both federal and Oklahoma state law. Under Oklahoma statute, hazing is a misdemeanor punishable by a fine of up to $1,500 upon conviction.

He drew a clear line between university discipline and criminal liability. University proceedings and criminal investigations are separate, Fuller wrote, and a university outcome does not resolve an organization's criminal exposure.

Fuller asked student leaders to review activities before they happen, report concerns promptly and preserve messages, group chats and photographs. He told recipients they do not need to determine whether conduct meets the legal definition of hazing before reporting it.

"Do not delay reporting to conduct an internal inquiry, discourage anyone from coming forward or delete relevant information," the letter states, according to the OU Daily.

Pattern of hazing findings

The two fall 2026 cases add to a growing list. OU's Campus Hazing Transparency Report, maintained under the federal Stop Campus Hazing Act signed in December 2024, now lists findings against six organizations.

Sigma Nu's case involved what the university described as a structured system of personal servitude and coerced domestic labor from August through October 2026. Pi Kappa Alpha's case involved mandatory physical exercises and a requirement that new members remain at the chapter facility when not in class.

Earlier this year, OU's chapter of Sigma Phi Epsilon was closed in February after the fraternity's staff discovered intensive hazing activity during the fall 2025 semester. The national board of directors voted to shut the chapter down. It was reinstated in June.

Fuller's letter also addressed sexual misconduct and assault. The annual security report showed on-campus rape incidents fell from 13 in 2024 to nine in 2025, while domestic violence rose from seven to 10 over the same period.

Reports of suspected hazing can be submitted through OU's Stop Hazing page or the OU Report It hotline at 844-428-6531, available 24 hours a day.
