Manhunt resumes for ex-LAPD officer on four-year anniversary of his firing

The search for Christopher Dorner, the ex-LAPD officer accused in a string of revenge murders entered its third day Saturday, authorities said, exactly four years after his dismissal from the LAPD. NBC's Miguel Almaguer reports.

Updated at 8:42 p.m. ET: The search for Christopher Dorner, the ex-LAPD officer accused in a string of revenge murders entered its third day Saturday in the snowy mountains of San Bernardino, Calif., authorities said, exactly four years after his dismissal from the LAPD.

Police say they believe Dorner is on a mission to execute former LAPD colleagues and superiors and their families to avenge his 2009 firing. They believe he murdered a retired captain’s daughter and her fiancé in Irvine, Calif., on Sunday, then killed one cop and wounded two others in shootings Thursday.

In an interview with San Francisco's KCBS, LAPD Chief Charlie Beck said Saturday that the department would re-examine the details that led to Dorner's dismissal.

Police spokesman Cmdr. Andrew Smith said the decision was made to ensure the public the LAPD is "fair and transparent" on Dorner's firing.

Dorner accused his training officer in August 2007 of kicking a mentally ill man during an arrest in San Pedro. An internal affairs investigation into his accusations concluded that the training officer had not kicked the mentally ill man and that Dorner's statements were false. He was later notified that he would be fired for making false statements.

Dorner's former boss and L.A. police chief from 2002 to 2009, William Bratton, said earlier that Saturday marked an important date in Dorner's history.

"Four years ago he received his discharge papers, if you will, his dismissal papers on Feb. 9, 2009," Bratton said. "A day of significance certainly in his mind that inasmuch as his grievances all seem to center on his dismissal."

A joint task force was established to continue the search for Dorner. The task force includes the Irvine Police Department, Riverside Police Department, Federal Bureau of Investigation, U.S. Marshall Service, Los Angeles Police Department and other allied agencies.

Los Angeles police deputies continued the manhunt at daybreak after relentless snowfall Friday evening forced them to suspend the search.

Los Angeles Police Chief William Braton, who was once the boss of Christopher Dorner, said Dorner is an "injustice collector" who finally reached a tipping point.

Bratton said it was clear to him that the triggering event in Dorner's life was his dismissal from the LAPD and said it was doubtful that he would give up and turn himself into police.

"He collects injustices and he never lets them go, and evidently they finally reached a tipping point that led to the series of violent acts the last several days," Bratton said. "The last thing that he would want would be to be arrested by the LAPD and do a perp walk. That would be the last injustice, the most significant one."

SWAT teams in camouflage began scouring the mountains Thursday after they found Dorner's burned-out Nissan near a ski resort in Big Bear Lake, about two hours from Los Angeles.

"It's extremely dangerous," San Bernardino County Sheriff John McMahon said at a news conference Friday, after more than 100 law enforcement officials scoured an 8-square-mile area using police dogs, snowmobiles and armored cars with chains to help navigate the terrain. 

Sheriff's officials said the search would continue until Dorner was located or evidence was found indicating he was no longer in the Big Bear area, NBCLosAngeles.com reported.

With gun drawn, two California Highway Patrol officers check the cargo of a truck leaving the Big Bear Lake area during a manhunt for Christopher Dorner who is suspected of the killing three people.

Police said they believe Dorner was acting on an online manifesto in which he baited authorities.

"Any threat assessments you generate will be useless," it read. "I have the strength and benefits of being unpredictable, unconventional, and unforgiving."

McMahon acknowledged that the hunt for a man who is effectively hunting them could be nerve-wracking.

"This business is not always safe," he said. "But this is what we train for."

Meanwhile, an attorney for two women who were shot by police during the search for Dorner said that the women met Saturday with Beck, who apologized.

Emma Hernandez, 71, was with her daughter Margie Carranza, 47, delivering newspapers in Torrance early Thursday when police opened fire on their truck. Hernandez was hit twice in her back and Carranza was injured by flying glass.

Attorney Glen Jonas said that the family appreciated the apology. Police said Beck was making arrangements to replace the women's truck.
