A man who was reported in the water near the Oceanside pier Saturday morning is presumed dead after a search last more than six hours was called off, officials said. The incident began just after 3:30 a.m. when Oceanside police and firefighters responded to reports that a man was in the water near the pier. It was unknown if the man fell or jumped. The man was spotted clinging to a pylon in the water. But as a rescue boat and a rescue swimmer entered the water, the victim lost hold of the pylon and went under, according to a news release from the Oceanside Fire Department. That triggered a search that involved Oceanside lifeguard, Oceanside Police Department Harbor personnel and the U.S. Coast Guard. But just after 10 a.m. the search was called off after the victim had not been spotted. The identity of the victim was not known. He was described as a male in his 20s.
