RIVERSIDE, Calif. -- Hundreds of tips prompted by a $1-million reward poured in to authorities seeking help finding the most wanted man in America: an ex-Los Angeles police officer who was charged in absentia Monday with murdering a policeman in Riverside.
With thousands of officers around southern California searching for Christopher Dorner, prosecutors in Riverside announced charges for last week's killing. Dorner also was charged with attempted murder for wounding another officer and firing at two others, Riverside County District Attorney Paul Zellerbach said.
Authorities obtained a no-bail arrest warrant, which allows Dorner to be apprehended anywhere, Zellerbach said.
The manhunt for Dorner, 33, began last Wednesday when he was named the suspect in the Orange County murders of a former Los Angeles police captain's daughter and her fiancé the previous weekend.
Hours after police announced they were looking for him, Dorner fired at two Los Angeles Police Department officers, then ambushed the Riverside officers.
"By both his words and conduct, he has made very clear to us that every law-enforcement officer in southern California is in danger of being shot and killed," Zellerbach said at a news conference that was guarded by four officers armed with rifles.
Police said Dorner wrote a lengthy manifesto that was posted to Facebook after the double murder.
He vowed deadly revenge on those in the LAPD responsible for his firing years earlier, and their families.
Police are providing protection for some 50 families thought to be targets.
The search for Dorner was focused in the mountains near Big Bear Lake, about 130 kilometres east of Los Angeles after his burned-out truck was found there last Thursday. That effort was scaled back over the weekend, when authorities announced the reward.
Police and city officials believe the reward, raised from public and private sources, will encourage citizens to stay vigilant.
More than 700 tips have come in since the reward was announced.
"Now it's like the game show Who Wants to be a Millionaire?' " said Anthony Burke, supervisory inspector for the U.S. Marshals regional fugitive task force.
The wide-ranging search has created unusually heavy traffic backups at California border crossings into Mexico, as agents are more closely inspecting each car.
State police in Mexico's Baja California were given photographs of Dorner and warned to consider him armed and extremely dangerous.
"I don't think he's done," Zellerbach said. "Just read his manifesto and look at his actions. He's trying to send a message, and it would be my belief that his message is not completed yet."
