The park has suspended dive operations in the search for Gerardo Escobedo, 50, of Lawndale, California, who drowned Sunday afternoon near Eighty-Three Dollar Cove in Lake Mohave. Park rangers will continue to make a daily search of the area by boat. Escobedo drowned near the mid-channel of the lake, where water depths range from 90 to 110 feet. Bullhead City Fire Department divers dove where he was last seen on Sunday, and Bullhead City Police Department divers dove on Monday without success. A search of the area was also made employing an underwater camera and sonar. According to witnesses, Escobedo jumped into the water to retrieve a lost hat. He went underwater and has not been seen since. He wasn't wearing a life jacket.
