Two people were killed today and two others critically wounded in a shooting at a Simi Valley tire shop.
Police officers found the victims when they responded to reports of shots fired at about 7:30 at a Tire Pros shop in a strip mall.
Two were dead and two others were taken to hospitals.
Police Sergeant David Livingstone says one of the dead might be the gunman.
The injured were taken to a hospital in critical condition.
Shop employe Damian Cervantes says he arrived at work to see police officers with drawn guns.
Cervantes says he heard that a customer was one of the dead and a supervisor is one of the injured.
