Los Angeles on Sunday announced a $1 million reward for information leading to the capture of an ex-cop accused of "domestic terrorism" in a murder spree that has claimed three lives. Investigators have been combing the snow-blanketed California mountains for Christopher Dorner, 33, a disgruntled former LA Police Department (LAPD) officer who had threatened to murder police in a chilling online manifesto, AFP reported. Some 50 LAPD officers and families have been placed under special protection.
