(Reuters) - Remains recovered from a burned-out California mountain cabin following a standoff between police and a gunman this week have been positively identified as those of a fugitive ex-Los Angeles policeman accused of a grudge-fueled killing spree.

The remains, which were charred beyond recognition, were conclusively determined by the San Bernardino coroner to belong to Christopher Dorner, who led Southern California police on a massive manhunt before he died on Tuesday after a shootout with authorities, the San Bernardino Sheriff's Department said.

Dorner, a former U.S. Navy lieutenant who was fired by the Los Angeles Police Department in 2008, was accused of killing four people, including a sheriff's deputy shot during his standoff on Tuesday in the San Bernardino Mountains.

The search for Dorner was described by authorities as the most extensive manhunt ever in Southern California.

An angry manifesto posted last week on Dorner's Facebook page claimed he had been wrongly terminated from the LAPD and vowed to seek revenge by unleashing "unconventional and asymmetrical warfare" on police officers and their families.

Can anyone verify this article? 

I have also thought if he was in the Navy then why did they not step in?
