UPDATE:

AVON-BY-THE-SEA -- Divers found a dead body Sunday in the search for a missing 17-year-old, Avon-by-the-Sea Police Chief Terence P. Mahon said.

The medical examiner would retrieve the body and confirm its identity, Mahon said.

The ANSWER dive team located the body at the base of a bridge in Shark River, Mahon said.

"We believe it to be the person we were looking for," he said.

Police and the Coast Guard have searched for the missing boy since Saturday. The 17-year-old was reportedly free diving and spear fishing when he went missing in the Shark River Inlet, Petty Officer Seth Johnson, a spokesman for the Coast Guard, said.

Searchers had deployed a boat and helicopter to find the boy Sunday morning, Johnson said.

The boy was from Westfield, the Asbury Park Press reported.

Mahon said police had not confirmed the identity of the body.
