SAN DIEGO — A 65-year-old woman is dead after she was found shot on the sand in Pacific Beach early Tuesday, San Diego police said. Around 12:30 a.m., police received a report that a woman had been injured in front of the 700 block of Reed Avenue, Lt. Jud Campbell said. Officers found the woman had suffered a gunshot wound to her upper body. Paramedics took the woman to a hospital, where she died. Police are still working to determine how the woman was shot, calling the death suspicious. “It is very early in the investigation and too soon to determine whether the woman was shot by someone else, if the injuries are accidental, or self-inflicted,” Lt. Adam Sharki said in a news release. Authorities have identified the woman but have not publicly released her name.
