When police arrived at the scene, a man was on the ground and a gun was recovered, but what prompted the shooting in those 12 minutes is still unclear.
The suspect was taken to a local hospital where he was pronounced dead.
"We don't know if that individual fired his weapon at the officer, but by indications, it looks like numerous rounds were fired," said Sgt. Rick Martinez, Anaheim Police Department.
"Right now, we have investigators combing the area to see where those rounds went and which directions they came from to see if that individual did fire his weapon at the officers and they returned fire, or if it was one way," Sgt. Martinez said.
The suspect was described only as a male in his 40s from the Anaheim area.
The suspect's car and a police car are both riddled with bullets.
The two officers were placed on paid administrative leave, which is standard procedure. The investigation into the shooting is expected to take several weeks.
The last officer-involved shooting in Anaheim was last October when officers were chasing burglary suspects. Resident Julian Alexander heard the commotion his home and came out, holding what police describe as either a broomstick or a shower rod. Alexander was shot twice in the chest and died at a nearby hospital.
His family has already filed a wrongful death suit against the city of Anaheim.
