Keileon Johnson, 21, was shot and killed on May 23, 2019 on County Road 3151 in DeBerry, Texas after an argument escalated into gunfire. Multiple 911 calls came in around 5 p.m.; deputies were told the victim was being driven to a hospital in a private vehicle. The driver flagged down an Inter-Community firefighter vehicle, but Johnson died at the scene and his body was later taken to Dallas for autopsy.

A second person suffered a gunshot wound to the hand and was taken to a local hospital. Tramaine Eugene Butler, 20, of DeBerry was arrested and charged with murder; investigators say Butler was still at the location when deputies arrived and that the shooting involved what appeared to be a rifle.
