On the evening of April 22, 2015, 21-year-old Matthew Anderson was found shot in his dormitory bed at the St. Louis Job Corps Center and was pronounced dead at the scene. Anderson had been at the center for only a day when a single gunshot to the chest ended his life.

Police locked down the campus, searched the grounds and interviewed students. Investigation attention soon focused on another student, 20-year-old Matthew Carlock, who had been at Job Corps for nine days. Carlock fled after the shooting but later surrendered; he was charged with first-degree murder and armed criminal action and held on a $1 million bond. No clear motive has been released.

Who knew Matthew Anderson at the Job Corps Center or has information about the events of April 22, 2015?
