A freak accident involving a dump truck has left one person dead in Mercer County, New Jersey Thursday afternoon.
Officials say it looks like a silver Nissan Altima was stopped at a red light on Business Route 1 in Lawrence Township when a dump truck slammed into it, pushing it off the roadway and into a nearby lake, before landing on top of it.
"All you hear is a big explosion -- and screeching tires, and you just hear 'pshhhh', like the water," said witness Daniel Tomeao.
The driver of the Nissan, who was trapped inside the vehicle, was pronounced dead on the scene.
The truck driver was taken to a local hospital.
It's unclear what caused the deadly crash, but investigators believe the truck driver, who was driving for Scorer's Sand and Stone, may have suffered a medical emergency before the crash.
A co-worker tells NBC10 that the driver passed a physical exam when he was hired just two months ago.
An investigation is underway.
