When Missouri Highway Patrol Trooper Russell Harper pulled over a pickup truck in February of 1987, the events that would follow changed the lives of his family, his fellow law enforcement and the armed man behind the wheel. That suspect was Glennon Paul Sweet and witnesses say he came out of his truck firing at Harper who died after taking a bullet above his eye. A description of Sweet prompts a massive multi-county manhunt. In this episode, former trooper Sam Kaunley describes the days-long hunt for the killer and the heart-stopping moment he was face-to-face with the man who killed his friend.
