"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 taskforce. "Instead of one contestant, we've got 100,000, and there's only one question you have to answer. All they have to answer is where he's at, and we can take it from there."
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.
Authorities have obtained a no-bail arrest warrant, which allows Dorner to be apprehended anywhere, Zellerbach said.
Dorner was fired from the LAPD five years ago, when a department board determined that he falsely claimed another officer had kicked a suspect. Randal Quan represented him during the proceeding.
Quan's daughter, Monica, and her fiance, Keith Lawrence, were found shot dead Feb. 3 in a car in the parking structure of their Irvine condominium. Last Wednesday, after discovery of the manifesto, Irvine police announced they were searching for Dorner.
Early Thursday in the Riverside County city of Corona, Dorner shot at two LAPD officers who had been dispatched to protect a possible target of Dorner's, police said. One officer's head was grazed by a bullet; the other was unharmed.
Minutes later, Dorner used a rifle to ambush two Riverside officers, killing one and seriously wounding another, authorities said. The slain officer was identified as Michael Crain, 34. The other officer's identity was not released to protect his family.
