The shooters fled in a black SUV after the rampage at about 11 a.m. inside the Inland Regional Center, a state-run center for people with developmental disabilities in San Bernardino, about 55 miles east of downtown Los Angeles, police said.

Police shot two suspects after a high-speed chase in a shootout hours later.

Police said “Explosive devices” were found inside the resource center during a secondary sweep and that they were rendered safe.

About 4½ hours after the shootings, police checking a lead in the nearby town of Redlands began chasing a car believed to be related to the incident, San Bernardino Police Chief Jarrod Burguan said.

A person named Syed Farook is listed in public records as a resident of the Redlands address from which police tracked the SUV involved in the shootout.

Dozens of SWAT team officers massed outside the facility, while police evacuated the occupants who filed out with their hands up.
