A Southern University in Louisiana graduate has been charged after he “turned himself in” for the violent hazing death of pledge and beloved marching band member Caleb Wilson — with police warning that more arrests are coming.

The death of a 20-year-old Southern University student in Baton Rouge, Louisiana, is being investigated by local law enforcement as a possible act of fraternity hazing, school authorities confirmed to The Associated Press on Wednesday.

Caleb Wilson, a junior at Southern University, died on Feb. 27. Unsanctioned fraternity activities may have caused his death, the university said.
