Oceanside-based scuba diver Jeffrey May, 45, went missing in La Jolla Shores on Memorial Day morning after he allegedly planned to meet up with a diving group. According to May’s wife, the 25-year diving veteran could not find the group he was supposed to meet up with. After he failed to return home or contact his wife for 12 hours, she called authorities to report him missing. Upon investigation, authorities discovered that May had rented scuba diving equipment from a nearby dive shop, although no one reported seeing him enter the water. May’s car was found in a nearby parking lot and a plastic tub holding his car keys, sunglasses and clothing was also found in a grassy area nearby. Lifeguards began the search on Monday night in murky water conditions with the aid of boats, onshore vehicles and a U.S. Coast Guard helicopter. The search was suspended close to midnight and resumed early Tuesday morning with nearly three-dozen divers, the federal maritime agency’s airborne personnel and a San Diego Harbor Police vessel laden with sonar equipment. At press time, May was still missing, said San Diego lifeguard Lt. Andy Lerum. — Mariko Lamb
