SAN BERNARDINO, Calif. (AP) – Fugitive ex-cop Christopher Dorner apparently killed himself as the cabin he was barricaded in caught fire following a shootout with officers, police revealed Friday while also confirming he spent most of his time on the run in a condominium just steps away from the command center set up to find him.

Authorities initially were unsure whether Dorner killed himself, had been struck by a deputy’s bullet, or had died in a fire that engulfed the cabin during the shootout, which included police sending tear gas canisters inside.

The search for Dorner began last week after authorities said he had launched a deadly revenge campaign against the Los Angeles Police Department for his firing, warning in a manifesto posted on Facebook that he would bring “warfare” to LAPD officers and their families.
