Authorities temporarily suspended their search until the following day, but expected to complete a search of more than 200 vacant cabins.
Overnight patrols were beefed up with 12 extra two-officer teams.
February 9: The search goes on
Bundled up in winter gear, search teams returned to the pine forests and trails surrounding Big Bear Lake in the San Bernardino Mountains.
Officers trudged through knee-high snow with rifles. Patrols again visited homes in Big Bear Lake, knocking on doors and peeking into windows.
February 9: Police to review Dorner complaint
Los Angeles police announced the department would reopen the investigation into the case that led to Dorner's termination.
"I do this not to appease a murderer," Chief Beck said in a statement. "I do it to reassure the public that their police department is transparent and fair in all the things we do."
Police vowed they would catch Dorner and urged the former officer to turn himself in.
In Big Bear Lake, resident Justin Owen said police asked him whether he had seen suspicious activity. No, he told them.
"I don't think he is up here, to be quite honest with you, in this quite brutal weather," Owen told CNN.
But his father, Ed Owen, said he thought Dorner may have been hiding in any of the houses that serve as second residences in the mountains and are often vacant.
"I would guess the occupancy rate on my block is just 10%," he said.
February 10: A $1 million reward
Los Angeles Mayor Antonio Villaraigosa announced a $1 million reward for information leading to Dorner's arrest and conviction. The reward includes funds from businesses, private donors and community groups.
"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.
