Chapin was last seen sometime between January and April 2006. She was living in Dent County, Missouri at the time. Chapman wasn't reported missing until November 2008, two and a half years after her disappearance. She has never been heard from again.
Chapin's stepfather, Gary McCullough, disappeared when she was thirteen years old. In 2003, Chapin went to Gary's brother Albert and told him her mother, Sandra McCullough, had shot Gary three times in the head and then made her help clean up the crime scene. Chapin said she cleaned the blood off the floor and she and Sandra wrapped Gary's body in plastic and burned it in a brush fire until only bone fragments remained. Albert recorded Chapin's statement and took the tape to the authorities, but Chapin quickly recanted and told her mother and law enforcement she'd made the story up.
Chapin disappeared approximately three years after she mad her statement. Her mother said she'd gone to Florida with a boyfriend in a black 2000 Chevrolet Cavalier. Sandra didn't report her missing; Chapin's father did, at the urging of the local sheriff. Chapin left a young son in Sandra's care; Sandra and her current husband have since adopted the boy. There hasn't been any activity on her Social Security number since 2006.
Gary was declared legally dead in 2005. In 2012, his two daughters filed a wrongful death lawsuit against Chapin, Sandra and Klemp, as well as Klemp's former wife, Jennifer Lee Brattin. The lawsuit alleges Sandra and Klemp were having an affair in 1999 and conspired to kill Gary, who planned to divorce his wife. In the summer of 2013, a trial jury unanimously awarded $8 million in damages to Gary's daughters in connection with his wrongful death.
It's unclear whether Gary and Chapin's disappearances are connected, but foul play is suspected in both cases.
