Christopher Dorner allegedly killed three people last week after being, in his opinion, wrongfully fired from the Los Angeles Police Department, sparking a statewide manhunt for the 6-foot, 270-pound former officer. A manifesto – that police believe was authored by Dorner, The Associated Press reports – threatens the families of officers and officials that the author believed had wronged him: “I will utilize every bit of small arms training, demolition, ordinance and survival training I’ve been given,” the manifesto reads. “You have misjudged a sleeping giant.”
