Christopher Karl Regan was 53 when he vanished from Iron River, Michigan, on October 14, 2014. Ten days after he was last heard from his ex-girlfriend reported him missing and investigators eventually focused on Kelly Cochran and her husband, Jason Cochran.

The Cochrans reportedly had a pact to kill anyone who cheated on them. Kelly allegedly lured Regan to their home; while the two were intimate, Jason shot Regan in the back of the head with a .22 rifle.

The case cooled after the killing, and the Cochrans moved to Indiana. In February 2016 Jason Cochran died of what first appeared to be a heroin overdose; Kelly later admitted she had given him a fatal dose and suffocated him. Kelly was arrested, confessed to involvement in Regan’s death, and was tried and convicted for Regan’s murder in May 2017, receiving life without parole along with convictions for conspiracy to commit disinterment and mutilation of a dead body. She also pleaded guilty to Jason’s murder and received an additional 65-year sentence. Family members told investigators they suspected Kelly in up to nine other deaths, and a neighbor said he thought he may have been served Regan’s remains at a barbecue hosted by the Cochrans.
