Kristyn Sue Richerson, 51, was last seen by friends at her Muskogee, Oklahoma, home on May 25, 2018. She was preparing to attend the Rocklahoma festival in Pryor and was described as unlikely to leave her home, her dog Buddy, or her family voluntarily. She is 5 feet 6 inches, about 200 pounds, with brown hair in a short fauxhawk, hazel eyes, reading glasses, a scar on the back of her right leg and an 8–10 inch Stevie Nicks tattoo on her right calf. On the day she vanished she was reportedly wearing a tan or beige shirt, camouflage pants and possibly a bandana.

Conflicting accounts emerged quickly. Roommate Carl Bryce told friends they went to the festival together and that Kristyn left with an unidentified woman, but cellphone records showed Kristyn’s phone never left Muskogee. Roommates Bryce and Cody Ray Campbell later sold or gave away some of Kristyn’s belongings; Bryce used her Oklahoma Access Card after her disappearance. Campbell later told police Bryce had stabbed Kristyn and buried her in the Houston Street backyard. A July 2018 search found a recently disturbed pile of dirt and the scent of decomposition, but no remains; first-degree murder charges were filed that day against an unidentified John Doe. The Muskogee Police Department considers foul play likely and the investigation remains active.
