The suspect posted a manifesto on his Facebook page, which included threats to harm police officials and their families. Two police detectives were guarding one of the people mentioned in Dorner's manifesto when the first shooting took place at 1:30 a.m. in Corona.

One officer sustained a head injury after he was grazed by a bullet. Another shooting occurred a short time later in Riverside. One officer was killed and the other was seriously wounded. The Riverside officers were on patrol when they were allegedly ambushed by the suspect. 

Dorner's manifesto details plans to seek revenge on Randy Quan, the father of Monica Quan who was shot and killed Sunday in Irvine along with her fiance, USC security officer Keith Lawrence. "I never had the opportunity to have a family of my own, I’m terminating yours," Dorner wrote.

Randy Quan is a retired LAPD officer who represented Dorner in a 2008 hearing. Dorner was accused of making false statements about another officer. Dorner pleaded innocent, but was fired from the LAPD in 2009.

The following are excerpts from the suspect's Facebook post:

"I know most of you who personally know me are in disbelief to hear from media reports that I am suspected of committing such horrendous murders. I know I will be vilified by the LAPD and the media. Unfortunately, this is a necessary evil that I do not enjoy, but must partake and complete for substantial change to occur within the LAPD and reclaim my name. . . ." 

"You're going to see what a whistle blower can do when you take everything from him -- especially his name. . . ."

"When the truth comes out, the killing stops. The attacks will stop when the department states the truth about my innocence publicly."

"In essence I've lost everything ... because the LAPD took my name and new (sic) I was innocent. Randy Quan new (sic) I was innocent but decided to terminate me."

A Riverside Christian Day School announced it will be closed Thursday due to the investigation. 

The 33-year-old suspect is considered "armed and extremely dangerous," according to authorities. Police believe he is driving a blue or gray Nissan Titan with the California license plate 8D83987 or 7X09131. Dorner is described as a 6 foot, 270 pound black male with black hair and brown eyes. 

Police Commander Andrew Smith said, "We're asking our officers to be extraordinarily cautious just as we're asking the public to be extraordinarily cautious with this guy. He's already demonstrated he has a propensity for shooting innocent people. We can't provide a lot of information now because we're trying to capture him. We don't know where he is. We're looking for the public's help to locate this guy. Anybody who sees him or believes they see him or his vehicle should call 911."
