Christopher Dorner was officially charged with murder Monday in Los Angeles, Ca., as the massive manhunt continues. Riverside District Attorney Paul Zellerbach, reportedly said that the 33-year-old former LAPD officer was charged with murdering one police officer and the attempted murder of three other officers—one from Riverside and two from the Los Angeles Police Dept. These charges will allow police to arrest the accused killer on sight.

According to NBC News, Zellerbach made clear at Monday’s press conference that the fugitive Dorner is a threat to every police officer in the area, adding that "by both his words and conduct, [Dorner] has made very clear to us that every law enforcement officer in Southern California is in danger of being shot and killed."

Dorner, who was fired from the LAPD in 2009, allegedly shot four officers on two separate incidents last Thursday in an apparent revenge plot for losing his job. The murdered officer is 34-year-old Michael Crain, an 11-year veteran and former Marine who served two tours in Kuwait. He leaves behind his wife, 10-year-old son and 4-year old daughter. The names of the other officers shot were not released.

Before his alleged shooting spree, Dorner had posted a manifesto on Facebook, which was later published by the LA Times. He targeted several officers for what he said was his unfair firing and also outlined rampant racism and abuse within the department.

The former police officer now charged as a cop killer, is also accused of killing an officer’s daughter and her fiancé on Feb. 3 in Irvine but no charges for those murders were filed yet.

More than 50 police officers and their families are now under 24-hour protection as Dorner remains at large.

During Sunday’s press conference, after announcing a $1 million reward for information leading to the capture of Dorner, Chief Charlie Beck called the ex-officer, who was once part of his team, “a trained assassin” and said that what he did was “an act of terrorism.”

Los Angeles Mayor Antonio Villaraigosa also spoke at yesterday’s press conference, saying that they will not tolerate the killing of police officers or their families. He added that it was not a matter of if they will capture Dorner but more a matter of when.

As much as the mayor sounded confident, the former cop remains on the loose as the dragnet to arrest him widens beyond the San Bernardino Mountains. The fugitive is reportedly well trained, skilled in survivalist techniques and has some experience flying planes. Authorities now fear he may make a run for Mexico and have heightened security and inspection at the California border crossing into Mexico. This in turn has caused heavy traffic delays.

On Monday, Customs and Border Protection joined the LAPD in the intense manhunt for Dorner.
