Police said Dorner began his run on Feb. 6 after they connected the Feb. 3 slayings of a former police captain's daughter and her fiance with his angry manifesto.

Dorner blamed former LAPD Capt. Randal Quan for providing poor representation before a police disciplinary board that fired him for filing a false report. Dorner, who is black, claimed in his online rant that he was the subject of racism by the department and was targeted for reporting misconduct by other police.

Chief Charlie Beck, who initially dismissed Dorner's allegations, said he would reopen the investigation into his firing — not to appease the ex-officer, but to restore confidence in the black community, which had a long fractured relationship with police that has improved in recent years.

Dorner vowed to get even with those who had wronged him as part of his plan to reclaim his reputation.

"You're going to see what a whistleblower can do when you take everything from him especially his NAME!!!" the rant said. "You have awoken a sleeping giant."
