Two possible suspects are down following a massive shootout, 1 mile south of the IRC building incident, involving police and a dark SUV. San Bernardino police cannot confirm whether the suspects were connected to the mass shooting.
San Bernardino police were chasing the dark SUV before the incident ended in gunfire, and one possible suspect was killed outside the vehicle.
Officers used special tactical equipment to approach the SUV where the body of the second possible suspect was pulled out.
One officer was struck in the shootout but did not suffer life-threatening injuries.
According to a federal law enforcement official, an ATF explosives enforcement officer was investigating a suspected pipe bomb recovered from a suspect.

Pipe bombs require planning and do not suggest crime of passion.
