A former Los Angeles police officer who authorities said wrote an online manifesto threatening to harm police officials and their families is wanted for allegedly killing the daughter of a former LAPD captain as well as the woman’s fiance.

Irvine police on Wednesday night named Christopher Jordan Dorner, 33, as the suspect of the double slayings in the parking lot of an upscale Irvine apartment complex. Officials warned that Dorner is armed and dangerous. Law enforcement sources said police have placed security at the homes of LAPD officials named in the manifesto and believe Dorner has numerous weapons.

The online postings on what the authorities believe is Dorner's Facebook page specifically named the father of Monica Quan, the Cal State Fullerton assistant basketball coach who was found dead Sunday, along with her fiance Keith Lawrence.

Randy Quan, a retired LAPD captain, was involved in the review process that ultimately led to Dorner’s dismissal.

A former U.S. Navy reservist, Dorner was fired in 2009 for allegedly making false statements about his training officer.

Thes online postings attributed to Dorner by authorities said that being police officer had been his life’s ambition since he served in the Police Explorers program. Now that had been taken away from him, the messages said, he suffered from severe depression and was filled with rage over the people who forced him from his job.

The postings have complaints that Quan and others did not fairly represent Dorner at the review hearing.

“Your lack of ethics and conspiring to wrong a just individual are over. Suppressing the truth will leave to deadly consequences for you and your family. There will be an element of surprise where you work, live, eat, and sleep,” they said, referring to Quan and several others.

“I never had the opportunity to have a family of my own, I'm terminating yours,” one passage said.
