Pacifica swimmer identified

assistance in the water off Sharp Park Beach, about 100 yards south of Clarendon Road.

When officers arrived, two separate groups said they saw two men and a woman on the beach who seemed to be drunk, police Capt. Dave Bertini said.

Police believe Serrano, a Redwood City resident, entered the surf and was knocked down by several waves. He never resurfaced, and had not been located as Saturday.

One of the man’s friends swam out to look for him but couldn’t find him, Bertini said. The two friends then walked away and told the nearby parties to call 911.

When police arrived, they began a search and rescue operation with the North County Fire Authority and the U.S. Coast Guard.

The Coast Guard sent a helicopter and two boats to comb a 45-square-mile area, Bertini said.

The search lasted about six hours, and crews used computer models to identify areas where a body could have gone.

Investigators have interviewed all people that were on the beach with Serrano, and determined that there is no evidence of foul play.
