On the evening of June 5, 2018, in Lebanon, Missouri, 47-year-old Gary Don Peterson was fatally shot after a confrontation in a residential neighborhood. Authorities found Peterson unresponsive in the roadway in the 500 block of Sweet Street after reports of a disturbance around 5:00 p.m. The Laclede County Coroner pronounced him dead at the scene.

Witnesses described a tense exchange involving Peterson, a woman, and the suspect, identified as Cashawn Ward Williams. According to those accounts, Williams approached and questioned the nature of the relationship, then drew a handgun and fired. One witness said Williams walked away after the first shot, then returned and shot Peterson again. Officers later executed a search warrant at Williams’ residence and recovered the vehicle used to flee, ammunition, and a box for a .40-caliber handgun matching shell casings at the scene. Williams was arrested on June 20, 2018, in Springfield by the U.S. Marshals Service with local assistance.

Peterson’s family remembered him as a father and grandfather who worked as a mechanic and enjoyed playing the guitar. Does anyone have information about Peterson’s life in Lebanon or witnessed the events on Sweet Street that evening?
