GARDEN CITY, N.Y.- Police say a man who crashed a truck into a utility pole and opened fire on a Long Island ambulance crew appeared to be on his way to carry out a mass killing.

Nassau County Police Commissioner Lawrence Mulvey says the 31-year-old man had strapped an assault rifle to his chest and extra ammunition to his forearms with wristbands.

He had six weapons in all, including a Tec-9 automatic pistol behind the seat of his truck. Police have not released his identity, but they believe he recently moved from Florida.

Shooting erupted Tuesday at about 10 p.m. in Bellmore after the driver hit a utility pole. When the volunteer ambulance crew arrived, he fired at least eight shots, wounding one of the emergency medical technicians. Police responding to the crash then shot the man when he threatened them.
