Post Mortem | Jocelyn Peters and the Notebook

March 17, 2026·24 min·2 clips

Investigators found potato fragments in the bedroom, believed to be used as a homemade silencer in Jocelyn Peters' murder.

A package did the work. Natalie Morales and Anne-Marie Green stay with the practical path investigators took after Jocelyn Peters was murdered. They followed the ways a package could get from St. Louis to Oklahoma until one delivery stood out. This was not guesswork. The package looked like it might hold a letter or something a little heavier, had about twenty five hundred dollars inside, and Cutler had signed for it. His phone added another piece. Green says Cutler's phone location put him at the crime scene too, and together those details led to his arrest. Then Morales turns to Cornelius Green, the school principal Jocelyn's friend described in severe terms. On paper, he looked like someone with everything in place. Green and Morales talk through the split between that image and what sat behind it. The word is facade. Green says the prosecutor called him an enigma because he had no criminal record and no history of violence. There was a wife. There was also a daughter, and Jocelyn's family says he told Jocelyn he was legally separated. Stephanie knew about Jocelyn, but the discussion says Stephanie thought they had broken up. His wife later filed for divorce. And there were other women. Green points to that number and brings in prosecutor Tiffany Becker to explain the pattern. The tone stays procedural, which makes the details land harder: a signature, a phone location, and a principal's polished exterior.
