The officer-involved shooting occurred March 3, and police now say they found a ghost gun on the suspect, 41-year-old Osman Brown.
According to Anaheim police, officers showed up when responding to a male suspect who had threatened a woman with a gun.
After surrounding the location, officers attempted to contact the suspect using de-escalation techniques, but the suspect refused to comply, the agency says.
