Deandre Darnell Duncan, Sr. was 37 when he was shot and killed on the evening of December 10, 2022, in the 8800 block of Edwin Street in Baton Rouge.

Baton Rouge Police detectives identified 31-year-old Christopher Davis as the primary suspect and say the shooting arose from that argument. With assistance from the U.S. Marshal’s Task Force, Davis was located and arrested on January 3, 2023, and booked on second-degree murder and illegal use of a weapon charges.

Later developments include an erroneous release and recapture of Davis in January 2025 and a separate shooting that wounded a planned trial witness; as of August 2026 the case remained pending. If anyone saw the December 10 argument on Edwin Street or has information about the shooting, please share what is known.
