"This search is not a matter of if, it is a matter of when," Villaraigosa said. "And I want Christopher Dorner to know that."

February 11: Warrant allows for Dorner's arrest 'anywhere'

As the manhunt entered its second week, a "no bail" warrant was issued for Dorner's arrest after the Riverside County district attorney filed a murder charge against the fugitive for the death of Riverside Police Officer Michael Crain.

"That allows him to be apprehended anywhere within California, out of state or out of the country," District Attorney Paul Zellerbach said.

Dorner was also charged with the attempted murder of three other police officers, including a Riverside officer who was wounded when Crain was killed. Authorities also said Dorner opened fire on two LAPD police officers, wounding one, in the suburban city of Corona.

February 12: Shootout kills deputy; body found in burned cabin might be Dorner's

California Fish and Wildlife wardens said they spotted Dorner driving a purple Nissan down icy roads, apparently tailing two school buses for cover.

Wardens chased the suspect, and a gun battle ensued. Gunfire struck a warden's car.

Dorner crashed, ran and quickly carjacked a pickup truck.

The fugitive fled to a nearby cabin and got into another shootout with San Bernadino County deputies, killing one and wounding another, authorities said.

Police tossed smoke devices inside the cabin, which caught fire and burned for hours.

Late Tuesday night, sheriff's investigators said they found charred human remains among the ashes of the torched cabin.

Authorities said it could be days before forensics experts can identify those remains.
