Teen dies when massive stone slab accidentally falls on him in New Jersey

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

Ocean County prosecutors say the 17-year-old was found at about 6:40 a.m. Saturday at Stone N' Counters South LLC in Berkeley Township. The business was closed when the accident occurred, and it's not clear why the teen was at the site.

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

The teen was pronounced dead shortly after authorities arrived on scene. His name hasn't been released.
