Two suspects—one male; one female—in the fatal San Bernardino shooting Wednesday morning were killed by police later in the afternoon, Police Chief Jarron Burguan told reporters.

Following up on tips, the chief said, led investigators to a home in Redlands, from which a suspicious vehicle was seen leaving. That led to a police chase back to San Bernadino, where the suspect vehicle was stopped and there was an officer-involved shooting.

One officer was wounded in that shooting. His injuries are considered non-life threatening.

The suspects were dressed in “assault-style clothing,” Burguan said, and were armed with assault rifles and hand guns. The race and age of the suspects has not been disclosed.

Burguan told reporters that officers were still working on clearing the Inland Regional Center, where several suspicious devices, one believed to be explosive, have been found.

A third person was seen running away from the officer-involved shooting, the chief said. That person has been detained. Police do not know if they were involved in the shooting.

Burguan also said that someone did leave the party at the IRC this morning after a dispute, but could not confirm whether that person was the gunman.

The assistant director of the FBI’s Los Angeles field office, David Bowditch, declined to answer questions about a potential motive. “The scene is strewn throughout the city. It’s incredibly fluid.”

There is a possibility that this could be a terrorist act, Bowditch said, and the FBI is adjusting its investigation to account for that possibility.
