A Palmdale man died Sunday afternoon after failing to surface from a recreational dive off the coast of the Palos Verdes Peninsula, U.S. Coast Guard officials said.

The victim was diving in the Flat Rock area 100 yards off the coast from a private boat with two friends when he failed to surface, said Capt. Abby Balderas with the L.A. County Lifeguards in Redondo. Redondo Beach Harbor Patrol and L.A. Country Lifeguards launched a search and found the unresponsive diver about noon.

A Coast Guard helicopter took the diver and a Los Angeles County paramedic to a hyperbaric chamber at Two Harbors, Catalina Island, where the diver was declared dead sometime after 1 p.m., said U.S. Coast Guard Lt. Ana Thorsson.

The L.A. County coroner’s office identified the victim as 58-year old Steven Dinsdale of Palmdale.

“The conditions were perfect for diving and lots of people were out there,” said Balderas. “It was just an unfortunate dive accident.”
