Sheriff Gore said officers were called to the Chabad synagogue just before 11:30am local time after the man opened fire with an "AR-15 type" assault rifle.
As the shooter fled the temple, an off-duty Border Patrol agent who had been inside the temple fired at his auto, hitting the vehicle but not the driver, Sheriff Bill Gore said. He also said that there are signs that the gun "might have malfunctioned after firing numerous rounds", according to CNN.
The sheriff said the shooting happened at 11:23 a.m. (2:23 p.m. ET).
The suspect, a 19-year-old white male whose identity was not immediately made public, fled the scene by vehicle and was arrested a short time later when he pulled over and surrendered to police, authorities said at a news conference.
Gore says a woman died from her injuries, while a girl and two men are in the hospital.
The suspect fled the scene and called 911 to say he was involved and give his location, San Diego Police Chief David Nisleit said.
"No one should have to fear going to their place of worship, and no one should be targeted for practicing the tenets of their faith", California Gov. Gavin Newsome said in a statement.
The post said he was training to be a nurse and cited the suspect accused of carrying out the deadly attacks on mosques in Christchurch last month, and at Pittsburgh's Tree of Life synagogue on October 27 where 11 people were killed. Trauma counselors were being sent to the synagogue, where about 100 people were awaiting interviews with homicide detectives.
