Devon Dee Lewis, 42, was killed inside a Tucson residence on March 29, 2021, after a dispute with a man he was living with escalated to gunfire. Responding officers found Lewis with gunshot wounds; he died at the scene despite first responders’ efforts.

Investigators say a confrontation between the two men preceded the shooting, though the precise nature of the disagreement has not been publicly detailed. The roommate was arrested and charged with murder after evidence collected at the home and witness interviews focused the investigation on him.
