Authorities combing the Big Bear area found no new signs of Christopher Dorner overnight but vowed Friday to continue searching until they found the ex-police officer or knew definitively that he had left the area.
In a morning update on the search, San Bernardino Sheriff John McMahon said more than 100 officers would be back in the field Friday after overnight efforts failed to yield new evidence and "certainly did not find" Dorner, the 33-year-old ex-LAPD officer sought in a series of shootings that have left three dead and two wounded.
McMahon acknowledged that Dorner had time to leave Big Bear but said authorities were not sure if he had done so. The search would continue, the sheriff said, until "either we discover that he left the mountain or we find him. One of the two."
