Chief William McManus says an unknown suspect shot 50-year-old Marconi twice in the head. Marconi was a 20-year veteran of the force.

McManus say the officer had pulled over a vehicle and while he was inside his squad car writing a ticket, a vehicle pulled up behind him. He says the driver of that vehicle then walked up to the officer’s driver-side window and opened fire.

He says he does not believe the original motorist pulled over had any relationship to the shooter.
