Robert Prewett, 92, was shot and killed while using a leaf blower in his front yard on Parc Charlene Drive in Florissant on the morning of Wednesday, October 30, 2024. St. Louis County officers found him at about 11:50 a.m. with three gunshot wounds; he was pronounced dead at the scene with his leaf blower still running nearby. Neighbors remembered him as a gentle, long‑time resident, a United States Air Force veteran and retiree from McDonnell Douglas, whose routine presence in the neighborhood made the killing especially shocking.

Investigators recovered home surveillance footage showing a person in a tan mask, gloves and jacket running from the scene and later discarding those items in a dumpster at a nearby apartment complex. Clothing seized from that dumpster produced a DNA match to a suspect. On November 8, 2024, the St. Louis County Prosecuting Attorney charged 18‑year‑old Da’Mon Williams of Florissant with second‑degree murder and armed criminal action; Williams was in custody in Illinois at that time and a $500,000 cash bond was set.

Does anyone have information about activity near Parc Charlene Drive on the morning of October 30, 2024 that could help investigators?
