The California ex-cop suspected of shooting 3 police officers Thursday, killing one, and in the double homicide of a college basketball coach and her fiance Sunday, remains on the loose, and "could be anywhere," law enforcement announced Friday. 

A former member of the Naval reserves, suspect Christopher Dorner posted a rambling manifesto railing against the Los Angeles Police Department - where he was fired for making false statements in 2009 -  and explicitly threatening LAPD officers and their families. 

He suspected of shooting at two LAPD officers Wednesday night - grazing one in the head - in Corona, Calif. The officers were reportedly providing security detail to someone named in his manifesto, according to police. Later on that same night, Dorner is also suspected of shooting two policemen at a stop light who were conducting a routine patrol in nearby Riverside. One officer was killed; the other is currently in surgery, according to Fox News.

Dorner is also suspected in the killings of Cal State Fullerton assistant women's basketball coach Monica Quan and her fiancé Keith Lawrence.

When Dorner was fired from the LAPD in 2009, Quan's father, a former LAPD captain who became a lawyer after he retired, represented Dorner at his trial in front of the Board of Fights, which ruled against him at the time of his termination, LAPD Capt. William Hays said to the Associated Press. Dorner tried to appeal his case in a Los Angeles court, but a judge ruled against him in 2011, according to court records, CNN reported

"Self preservation is no longer important to me. I do not fear death as I died long ago on 1/2/09," Dorner wrote, likely referring to his firing, Fox News reported.

"In this case, we're his target," Sgt. Rudy Lopez from the Corona Police Department said at a press conference, Fox News reported.

Police have narrowed their search area down to the Big Bear Mountain ski area where Dorner's burned out truck was discovered, roughly 80 miles east of Los Angeles, according to KBTX. Authorities have been out in full force searching for Dorner, with 125 officers going door-to-door and a SWAT team backing them up, San Bernardino Country Sheriff John McMahon said, KBTX reported. Police will continue to search for as long as conditions allow, he said. 

"I never had the opportunity to have a family of my own, (so) I am terminating yours," Dorner reportedly states in his manifesto.

He continued: "Look your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead," CNN reported.
