Gabriel Kaine Duncan, 35, was found dead from multiple gunshot wounds inside his Parsons, Kansas, home on August 5, 2026. Parsons police responded about 1:30 p.m. to the 1200 block of Southwest 10th Street and discovered Gabriel deceased at the scene.

Authorities identified his younger brother, 27-year-old Billy Ray Duncan, who also lived in the residence, as the alleged shooter. Officers arrested Billy Ray at the scene without incident. The Labette County Attorney charged him with first-degree murder and criminal possession of a weapon by a felon. Reports describe the killing as domestic violence-related and say there was a history of conflict between the brothers.

Billy Ray Duncan has prior convictions for aggravated endangerment of a child, fleeing or attempting to elude law enforcement, and drug offenses. The investigation is ongoing; there has been no trial, conviction, or sentencing reported.
