Los Angeles on Sunday put up a $1 million reward for the capture and conviction of Christopher Dorner, a dismissed officer believed to have killed three people in the state, including another cop.

“We will not tolerate anyone undermining the security, the tranquility of our neighborhoods and our communities,” Los Angeles Mayor Antonio Villaraigosa told reporters. “We will not tolerate this reign of terror that has robbed us of the peace of mind that residents of Southern California deserve. We will not tolerate this murderer remaining at large.”
