The DeKalb County Sheriff's Office says 22-year-old Steven Schultz died of a self-inflicted gunshot wound.
Schultz's body was pulled from the river near Route 72 and Annie Glidden road back on July 9th.
Friends say Schultz had told them he was on his way to meet a man near Kirkland to buy a gun. Police were alerted when he never returned. Dive teams found his body only days later.
