LOS ANGELES (AP) — A fired police officer who threatened to bring "warfare" to the Los Angeles Police Department went on a shooting rampage that left a policeman and two others dead and set off an extraordinary manhunt that had three states and Mexico on alert for much of Thursday.
The search for Christopher Dorner led hair-trigger officers to mistakenly shoot at innocent citizens and forced police to guard their own.
But the focus of police efforts shifted Thursday afternoon to the snowy mountains around Big Bear Lake, about 80 miles east of Los Angeles, where police found Dorner's burned-out pickup truck and tracks leading away from the vehicle.
San Bernardino County Sheriff John McMahon said 125 officers were going door to door and attempting to track the suspect, and that a SWAT team was providing added security to those in the community. Schools were put on lockdown while investigators examined the vehicle and spread out across the area.
"He could be anywhere at this point, and that's why we're searching door to door," McMahon said, adding that the manhunt would continue "as long as we can." A snow storm was expected in the region with temperatures dipping into the teens overnight.
Said LAPD Assistant Chief Michel Moore: "This complex and violent investigation has led to this mountain."
The pickup was to be processed at a crime lab Thursday evening and examined by investigators from multiple agencies.
Throughout the day, thousands of heavily armed officers patrolled highways throughout Southern California, while some stood guard outside the homes of people police say Dorner vowed to attack in a rant posted online. Electronic billboards, which usually alert motorists about the commute, urged them to call 911 if they saw him.
"I will bring unconventional and asymmetrical warfare" to Los Angeles Police Department officers, on or off duty, said the manifesto. It also asserted: "Unfortunately, I will not be alive to see my name cleared. That's what this is about, my name. A man is nothing without his name."
