As the manhunt for the renegade ex-cop accused of killing three people in a revenge plot targeting the Los Angeles Police Department enters its second week, the big question facing authorities is: Where is Christopher Jordan Dorner?
The search, considered one of the largest in the history of Southern California, has taken authorities from Orange County to the border of Mexico, from Los Angeles to the Big Bear Lake resort area of the San Bernardino Mountains.
Even so, a week after Dorner allegedly began targeting police officers and their families, putting the region on edge, there was no sign of the man on Monday.
A "no bail" arrest warrant was issued for Dorner after the Riverside County district attorney filed a murder charge Monday against him in the killing of Riverside Police Officer Michael Crain.
"That allows him to be apprehended anywhere within California, out of state or out of the country," District Attorney Paul Zellerbach told reporters at a news conference Monday.
The murder charge is accompanied by two "special circumstances," including killing a police officer on duty and firing a weapon from a vehicle, Zellerbach said.
Dorner was also charged with the attempted murder of three other police officers, including a Riverside officer who was wounded when Crain was killed. That officer, whose name has not been made public, is in a lot of pain and faces "many surgeries," Riverside Police Chief Sergio Diaz said.
The other two charges accuse Dorner of opening fire on two LAPD police officers, wounding one, in the suburb of Corona.
Los Angeles police spokesman Lt. Andy Neiman said the department had received more than 700 tips on Dorner's whereabouts. Some of the calls have come from Dorner's past acquaintances or people who think they have spotted the fugitive.
The city of Los Angeles put up $1 million in reward money Sunday for help catching Dorner, an announcement that followed news that the LAPD was reopening the case that resulted in his termination.
Dorner accused his training officer of kicking a mentally ill man during an arrest in 2007. The LAPD ruled the complaint unfounded and booted Dorner off the force for filing a false complaint. He challenged his firing in court and lost.
In a manifesto released last week, Dorner blamed racism and corruption in the LAPD for his termination and vowed to wage "unconventional and asymmetrical warfare" against LAPD officers and their families. He called it a "last resort" to clear his name and strike back at a department he says mistreated him.
LAPD Chief Charlie Beck had a different term for it Sunday.
"This is an act -- and make no mistake about it -- of domestic terrorism," he told reporters Sunday during a televised news conference. "This is a man who has targeted those that we entrust to protect the public. His actions cannot go unanswered."
Authorities say Dorner began making good on his threats on February 4 when he allegedly killed Monica Quan and her fiance, Keith Lawrence, in an Irvine parking lot, south of Los Angeles.
Quan was the daughter of a now-retired Los Angeles police officer, who represented Dorner during the disciplinary hearing that resulted in his firing. The officer was among dozens named in the manifesto.
The retired officer told investigators that he received a call from someone identifying himself as Dorner who told him he "should have done a better job of protecting his daughter," according to a federal arrest warrant affidavit. Investigators traced the call to Vancouver, Washington, but based on the timing of other sightings, they don't believe Dorner was in Vancouver at the time, the affidavit states.
Days later, early Thursday morning, Dorner allegedly opened fire on two LAPD police officers, wounding one, in the suburban city of Corona.
Roughly 20 minutes later, Dorner allegedly fired on two officers in the nearby city of Riverside, killing one and wounding another. On Sunday, authorities identified the slain officer as Michael Crain, an 11-year veteran of the Riverside Police Department.
