No cause of death has yet been determined for a 54-year-old Chula Vista man who died while scuba diving off La Jolla Shores Beach, according to the San Diego County medical examiner.
Lawrence Yates was found by lifeguards floating face-down Saturday afternoon near the south end of the beach. He may have been trapped against a sea wall, according to lifeguards.
Yates was taken to Scripps Memorial Hospital in La Jolla, where he was pronounced dead.
