San Bernardino officials hold a news conference in Big Bear to provide updates on the Chris Dorner search.
The 33-year-old ex-LAPD officer is wanted in connection with the shootings of three police officers in the Inland Empire and a double murder in Irvine.
His burned-out pickup truck was found near Bear Mountain on Thursday afternoon. Investigators have been searching the area and going door-to-door and looking for new tracks in the snow.
As a precaution, all Bear Valley Unified schools are closed Friday.
