WELLFLEET — A man who was bitten by a shark at a Wellfleet beach Saturday has died, according to police.

Wellfleet police Lt. Michael Hurley confirmed at 2:25 p.m. that the shark attack victim died of injuries at Cape Cod Hospital.

The 26-year-old man is from Revere, according to Massachusetts State Police.

Leslie Reynolds, chief ranger at the Cape Cod National Seashore, confirmed the incident happened about 300 yards south of Newcomb Hollow Beach.

Reynolds said Seashore rangers and Wellfleet police performed CPR on the victim on the beach after the bite. The person had not been pronounced dead at that time, Reynolds said.

Wellfleet police confirmed at 1 p.m. that the victim was en route to Cape Cod Hospital by ambulance.

According to off-duty lifeguard Adriana Picariello, the man had injuries to his lower extremities and no pulse while he was being attended to on the beach.

Picariello and two other off-duty Wellfleet lifeguards were at Newcomb Hollow at the time of the attack and assisted with medical help.

A 61-year-old New York neurologist was bitten by a great white shark Aug. 15 at Long Nook Beach in Truro. The man survived the bite.

The most recent fatal shark attack in Massachusetts was at Hollywood Beach above Mattapoisett Harbor in Buzzards Bay in 1936. Nearly 40 years prior, in 1897, a man fishing south of Lynn was killed.

Witness Joe Booth described a harrowing scene at the Wellfleet beach when the incident occurred.

“I saw a worst nightmare unfold here,” Booth said. “Some gentleman got bit by a shark. We never wanted anything like this to happen, ever. Anywhere,” he said.

Booth said it was a quiet day at the beach and saw some people boogie boarding before he noticed some commotion in the water.

“Just a giant eruption of water. 15 feet-wide. I saw a tail and a lot of thrashing,” Booth said. “You could tell by the body language of the guys in the water something wasn’t right.”
