SAN DIEGO - A body that washed ashore on South Mission Beach could be that of a missing boater who disappeared after his boat capsized in Mission Bay.

Lifeguards reported finding the body at the foot of San Fernando Place in South Mission Beach at about 4:10 p.m. Monday.

Earlier in the day, authorities were searching for the missing boater – identified by family members as Edgar Paglumotan – who disappeared after his boat overturned near the north end of the ocean entrance to the harbor about 12:30 a.m.

City lifeguards notified the U.S. Coast Guard a short time later that one man who had been aboard the boat was able to swim to shore and was transported to a trauma center, according to USCG public affairs.

However, his 50-year-old companion, Paglumotan, was missing.

The federal maritime agency launched an MH-60 Jayhawk helicopter and a 45-foot boat to search for Paglumotan. Police, firefighters and lifeguards also took part in the effort, which continued through the morning and into the afternoon.

The Coast Guard suspended its search at 2 p.m., USCG Petty Officer Connie Gawrelli said. About two hours later, lifeguards reported finding a body believed to be that of the missing boater near the area where the vessel had capsized, she said.

A lifeguard spokesman told 10News a photo of the missing boater resembles the person who washed ashore. The Medical Examiner's Office has been notified and will positively identify the body.

Authorities did not disclose the nature of the injuries suffered by the survivor, whose name was withheld.
