New Jersey teen killed when massive stone slab accidentally falls on him

BERKELEY TOWNSHIP, N.J. -- Authorities say a teenage boy was killed when a stone slab weighing about 650 pounds fell on him outside a business that makes countertops.

Ocean County prosecutors say the 17-year-old boy was found around 6:40 a.m. Saturday at the Berkeley Township business. It was closed when the accident occurred, and it's not clear why the teen was at the site.

It appears that the boy was trying to walk between marble and granite slabs when a massive slab fell on top of him. But it's not clear how long he had been trapped there before a passing motorist spotted him and called police.

The teenager was pronounced dead shortly after authorities arrived on scene. A cause of death has not been determined, and his name has not been released.
