On the evening of July 30, 2015, 16-year-old Desean Mitchell was fatally shot on Hudson Lane in the Fern Creek neighborhood of Louisville, Kentucky. Desean, who was about to enter his junior year at Southern High School, was with a group of friends when a single gunshot to the head proved fatal. Neighbors performed CPR and he was taken to University Hospital, where he died during surgery.

A friend who was at the scene and is a minor told investigators the shooting was an accident: another friend reportedly found a gun in the neighborhood, removed the clip, believed it was unloaded, pointed it at Desean as a joke and pulled the trigger. In the days that followed, 17-year-old Michael Williams was arrested and charged with murder; the case was transferred from juvenile court to adult court after a grand jury indictment. Desean’s mother described him as silly, lovable and respectful, and said the loss felt like a piece of her heart was gone.

If anyone knew Desean or has information about what happened that night, please share what you know.
