NBC NATIONAL NEWS — A massive manhunt continues in southern California for an ex-LAPD officer that police blame for three murders.
33-year-old Christopher Dorner may have laid out his plans for revenge in a manifesto that law enforcement is using to predict his next move, but on Friday officials admitted he's likely no longer in the area they've been searching.
"We're going to continue searching until we discover either that he left the mountain, or we find him. One of the two," said San Bernardino County Sheriff John McMahon.
Police fear Dorner could be hunting them.
Worsening weather is hampering a massive search of the Big Bear Mountain area east of Los Angeles
where Dorner was spotted last, allegedly engaging in a shootout with officers and setting his vehicle on fire.
Police followed tracks leading away from the truck, with no luck.
The ordeal began Sunday, when a woman and her fiance were found murdered in Irvine, California.
Officials quickly realized she was the daughter of a retired LAPD captain who represented Dorner
at disciplinary hearings before he was fired in 2009.
On Thursday police believe Dorner shot three officers in Riverside and Corona, killing one.
According to a Facebook manifesto police attribute to him, Dorner's anger has been simmering since he joined the force.
The manifesto accuses the LAPD of betraying and destroying lives, including his, and says the killing will stop "only when the truth comes out".
Meanwhile, police involved in the manhunt are facing harsh criticism after firing on two trucks they feared might be Dorner's.
A 71-year old woman delivering newspapers was shot multiple times in her back, and her daughter was also injured.
A third person was unhurt.
