Yancey Knoll was shot multiple times while stopped at a red light, leading to a citywide manhunt for the shooter. Witnesses described hearing gunshots and seeing a silver BMW speed away. Investigators quickly ruled out road rage, as Knoll had no known enemies.
Dan Bowman, an engineer with a seemingly perfect life, emerged as a suspect after a witness provided a detailed description of the shooter. Police discovered Bowman's obsession with murder-related materials on his computer, raising questions about his motives.
