Ronald Everett Wilkson, 55, and his wife Valerie Kay Wilkson were killed at their home in Luther, Oklahoma, near Wellston on October 23, 2016. Ronald, a former truck driver and mechanic known for keeping his lawn in meticulous condition, was both shot and viciously stabbed; investigators said wounds to his neck were consistent with an attempt to sever his head. Valerie Wilkson was also found with severe injuries. The Oklahoma County Sheriff characterized the killings as a rage killing.

Authorities later tied the double homicide to the couple’s nephew, Michael Vance, who had earlier shot two Wellston police officers and carjacked a vehicle before arriving at the Wilkson residence. Vance fled in the couple’s car, posted videos to social media while evading capture, and was the subject of a multiagency manhunt. The pursuit ended when Vance was killed in a shootout with an Oklahoma state trooper near Leedey, about 130 miles northwest of Oklahoma City. Prosecutors filed two counts of first-degree murder against Vance prior to his death.
