Allison Douglas Doug Arp was a 55-year-old welder and longtime resident of the rural Bentley area outside Atoka, Oklahoma. On the evening of November 30, 2017, deputies and Oklahoma State Bureau of Investigation agents responded to a shooting at his home on South Bentley Road and found him mortally wounded by a rifle shot to the chest. The medical examiner took custody of the body and forensic teams documented the scene and bullet trajectory.

Douglas’s adult son, Wyatt Arp, initially told a 911 dispatcher the .22-caliber rifle had been leaning against a wall, fell and discharged when a door was slammed. After further questioning, Wyatt gave a different account, saying an argument led him to leave and return, that he crawled in through a window, picked up a loaded rifle and that his thumb slipped as he tried to move it, causing the gun to fire. Investigators said medical findings suggested the rifle had been almost directly in front of Douglas when it fired, a detail they weighed against Wyatt’s statements.

Wyatt was arrested on a complaint of first-degree murder on December 4, 2017; court records showed he was on probation for a prior assault on his father. If anyone knew Doug Arp or has information about that night, please share what you know.
