Part 2/3:
The arrest occurred after an employee at a local McDonald’s recognized Mangion. Acting on instincts, the employee contacted local police when they noticed his suspicious behavior. Responding officers quickly arrived at the scene to conduct a thorough investigation.
Discovery of Evidence
Upon questioning, Mangion displayed increasingly suspicious behavior. Further investigation revealed a troubling collection of items on his person: multiple fraudulent IDs and a U.S. passport. However, the most alarming discoveries were made when officers recovered a firearm and a suppressor that matched the weapon reportedly used in the murder of Brian Thompson.
