THE MANHUNT FOR CHRISTOPHER DORNER
Law enforcement agencies issued a Blue Alert throughout Southern California on Thursday as the manhunt for a former police officer suspected of killing three people spread into the Big Bear area.

Christopher Jordan Dorner, a 33-year-old La Palma man, is believed to be targeting police officers in a revenge plot after he was fired from the Los Angeles Police Department in 2008.

Inspired by the Amber Alert notification system that alerts the public to abducted children, the Blue Alert system was enacted in January 2011 to notify the public of individuals on the lam who are suspected of killing or seriously injuring peace officers, said Officer Mario Lopez of the CHP's Inland Division in San Bernardino.

The system alerts the public to the suspect's physical description, as well as a description of the vehicle they are driving and its license plate number.

Thursday was the third time the Blue Alert system has been activated since it went online more than two years ago, Lopez said.

The alert was first utilized on May 6, 2012 following the attempted murder of a CHP officer in Bakersfield.

Roughly four months later, on Sept. 4, 2012, the system was used for the second time following the fatal shooting of CHP Officer Kenyon Youngstrom, Lopez said.

He said California is among 15 states that currently use the Blue Alert system.

Thursday's activation followed the early morning shooting death of a Riverside police officer.

Lopez said the CHP sent a picture of Dorner and a photograph of his vehicle to all 25 of the CHP's communication centers and CHP personnel statewide.

According to an online manifesto by Dorner, he is attacking police officers to clear his name.

"Unfortunately, this is a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name," Dorner said in the manifesto.

Dorner is wanted in the killings of Cal State Fullerton assistant basketball coach Monica Quan and her fiance, Keith Lawrence. The killings took place on Sunday in Irvine.

Quan is the daughter of a police captain who represented Dorner in an LAPD departmental hearing that led to his firing.

Authorities say Dorner also ambushed two Riverside officers early Thursday morning, killing one.

The Blue Alert was issued in the counties of Kern, Santa Barbara, Ventura, Los Angeles, San Bernardino, Orange, Riverside, San Diego and Imperial.
