On the afternoon of April 5, 2021, 30-year-old William T. Cooper was shot and killed in the Bevo Mill neighborhood of St. Louis. Officers responded about 2:40 p.m. to the 4600 block of Gravois Avenue near Itaska Street and found Cooper suffering from a gunshot wound to the torso; he was pronounced dead at the scene.

Police say the killing was part of a brief, violent spree by 33-year-old Anthony Dwayne Brown that unfolded across the city within roughly an hour. Investigators reported the violence began with a domestic dispute involving Brown and his former girlfriend, and that Brown had made threats the day before. On the day of the shootings Brown allegedly exchanged gunfire with Cooper earlier on Neosho Street and also fired at the ex-girlfriend and her teenage brother in a Family Dollar parking lot. Less than fifteen minutes after that incident, Brown is accused of driving past a parking lot on Gravois Avenue and firing a 9mm Beretta out his window, striking Cooper.

What details about Cooper’s movements that afternoon or potential witnesses have not been made public?
