southern california gunman ambushes officers

While authorities continue their search for ex-LAPD officer Christopher Dorner, more about his motivation for shooting cops, and killing a couple has been revealed. According to his manifesto, the shooting spree was brought on by racism, and other injustices he witnessed while on the force.

Police in Southern California announced Wednesday (Feb.6) that they are looking for a former LAPD officer implicated in the double murder of a newly engaged couple on Super Bowl Sunday. Christopher Jordan Dorner was upset over being fired and sought revenge against victims, Monica Quan and Keith Lawrence.
