A Business Partner's Testimony: Inside the Interrogation of a Love Triangle Murder

The morning of October 4th, Monnie woke up late, around 10:30. Her car battery was dead. Her son was home sick from school. She was tinkering in the garage when the radio started reporting that a woman had been killed. By mid-afternoon, her mother called with the news: the victim was the pregnant girlfriend of Sean—a former NFL player, her business partner, and the man she had been seeing for six years. When Monnie tried calling Sean to see if he was okay, his phone went straight to voicemail. He never called back.

This interrogation, conducted by detectives from a multi-agency task force in Lake County, captures the police interview with Monnie in the aftermath of that murder. The transcript reveals how investigators methodically worked through a web of relationships, threatening letters, and compartmentalized secrets to understand whether Sean—or someone connected to him—was responsible for the killing.
