CRESCENT BEACH, Fla. (AP) – Rescue crews rescued a man who became trapped when a sand tunnel collapsed on him on a beach in St. Johns County.

St. Johns County Fire Rescue Sgt. Lucas Smith tells the Florida Times-Union crews found the man under almost 3 feet of sand in a dug-out hole next to the dunes on Sunday afternoon near Crescent Beach.

Lucas says the man, whose name hasn’t been released, appeared to be middle-aged.

Crews had to remove the sand to reach him and he was in cardiac arrest.

The cause of the collapse is under investigation by the sheriff’s office.
