What we know about suspects in fatal San Diego mosque shooting

Within minutes after shots rang out at a San Diego mosque, killing three people, police knew the threat was "neutralized" when they found the bodies of the two suspected shooters, the city's police chief says.

Chief Scott Wahl said at a news conference that both suspects in the May 18 attack are dead and were found in a car just blocks away from Islamic Center of San Diego. They were 17 and 19 years old, both male and are believed to have died from self-inflicted gunshot wounds, Wahl said.

The active shooter call at the mosque came in at about 11:43 a.m. PT, he said. As police responded, they got another call about a landscaper being shot at while he was working a couple blocks away from the mosque, though he wasn't hit. And then "moments later," officers got a call about a car in the middle of the street. Inside, police found the suspect shooters dead, Wahl said.

"The circumstances that led up to this and the details of what happened and exactly which time it happened will come out in the days ahead," Wahl said.

He said the attack was being investigated as a hate crime and the FBI is assisting in the investigation.

Authorities didn't identify those killed in the shooting or the suspects. In the coming hours, days and weeks, they will be working to learn everything they can about the shooters and why they attacked the mosque.

This is a developing story and will be updated.
