Baton Rouge police are investigating the death of a 20-year-old Louisiana student as a possible fraternity hazing incident, a school spokesperson said.

Caleb Wilson, a junior at Southern University and A&M College, died Feb. 27 after he attended an off-campus event. The university said Wednesday on Facebook that an internal investigation had been launched following reports that the event was unsanctioned.

“The University has begun the student judiciary process as prescribed by the University’s student code of conduct and aligned with Louisiana law,” the school said. “All organizations on campus are required to undergo rigorous anti-hazing training and are held to high standards related to membership intake processes. Any breaches of these policies prompt disciplinary sanctions.”

Wilson was at a gathering with members of Omega Psi Phi, according to WVUE-TV of New Orleans. He was unresponsive when he was taken to the hospital.

“Our hearts go out to his family, friends, and all who were touched by him,” the fraternity has said in a statement.
