Christopher Dorner, the ex-LAPD cop accused of killing two civilians in Irvine and a police officer in Riverside County, is the subject of a massive manhunt in Southern California. According to the service records obtained by 10News, Dorner has also served in the Navy Reserves from 2002 and his loss date was Feb. 1, 2013 — days before the shootings began.

Dorner was assigned at several locations throughout his service years, and earned numerous awards including medals for National Defense Service, the Iraq Campaign, Sea Service Deployment, and pistol expertise, as well as honors for rifle marksmanship.

On Sunday, Dorner allegedly shot Monica Quan, daughter of retired LAPD Captain Randy Quan, and her fiance in their car. Irvine police Lt. Julia Engen said there was no evidence that the slain couple were being robbed.

Dorner has blamed Randy Quan for his firing from the police force.

The Irvine incident was  followed by a shooting spree in Riverside County which left one police officer dead.

Dorner’s whereabouts remain undetermined, prompting authorities to heighten their efforts to get the 33-year-old fugitive in custody.

In his manifesto, Dorner thanked the U.S. Navy for re-enforcing “Honor, Courage, and Commitment” in him. He also revealed that he lost his Commanding Officer position in the Navy because of the LAPD.

“The LAPD has suppressed the truth and it has now lead to deadly consequences. The LAPD’s actions have cost me my law enforcement career that began on 2/7/05 and ended on 1/2/09. They cost me my Naval career which started on 4/02 and ends on 2/13. I had a TS/SCI clearance(Top Secret Sensitive Compartmentalized Information clearance) up until shortly after my termination with LAPD,” Dorner wrote. “This is the highest clearance a service member can attain other than a Yankee White TS/SCI which is only granted for those working with and around the President/Vice President of the United States. I lost my position as a Commanding Officer of a Naval Security Forces reserve unit at NAS Fallon because of the LAPD.”
