William Clifford was 31 when he was killed in the early hours of September 6, 2020, after a violent dispute at a house party on Rapid City’s south side. Police were called about 3:00 a.m.; officers found Clifford in a garage with a gunshot wound to his abdomen and he died at the scene despite efforts to keep him alive. Another person was shot and survived with serious injuries.

Investigators early on said evidence suggested drug use may have contributed to tensions at the party. Authorities announced they had a suspect while the search continued and on September 16 a deputy stopped a vehicle with no license plates; occupants ran, a drone-assisted search followed, and Jamys Flying Horse was found hiding in a creek and arrested on charges including first-degree murder and attempted first-degree murder. Prosecutors later dropped those charges in connection with Clifford’s death and the other shooting, leaving the case without a public courtroom resolution in that filing.

If anyone has information about the shooting, the people who were at the party, or events that night, please come forward.
