Ex-LA Cop Sought in Shootings of 3 Cops, 2 Slayings Feb. 7, 2013 - Police in Southern California say they suspect that a fired cop is connected to the shootings -- one fatal -- of three police officers this morning, as well as the weekend slayings of an assistant women's college basketball coach and her fiancÃ© in what cops believe are acts of revenge against the LAPD, as suggested in the suspect's online manifesto. Former police officer Christopher Jordan Dorner, 33, who's a U.S. Navy reservist, has been publically named as a suspect in the killings of Monica Quan, 28, and her 27-year-old fiancÃ©, Keith Lawrence, Irvine police Chief David L. Maggard said at a news conference Wednesday night. "We are considering him armed and dangerous," Lieutenant Julia Engen with the Irvine Police Department said. Police said three police officers were shot early this morning: one in Corona, Calif., and two in Riverside, Calif. The Riverside Police Department said one of its officers was killed, KABC-TV reported. The conditions of the two other officers were not immediately released. Police reportedly suspect a connection to Dorner. Police around Southern California are wearing tactical gear, including helmets and guns across their chests. The light-up signs along California highways show the license plate number of Dorner's car, and say to call 911 if it is seen. The problem, police say, is that they believe Dorner is switching license plates on his car, a 2005 charcoal gray Nissan Titan pickup truck. Lawrence was found slumped behind the wheel of his white Kia in the parking lot of their upscale apartment complex Sunday and Quan was in the passenger seat. "A particular interest at this point in the investigation is a multi-page manifesto in which the suspect has implicated himself in the slayings," Maggard said. Police said Dorner's manifesto included threats against members of the LAPD. Police say they are taking extra measures to ensure the safety of officers and their families. The document, allegedly posted on an Internet message board this week, apparently blames Quan's father, retired LAPD Capt. Randy Quan, for his firing from the department. "Your lack of ethics and conspiring to wrong a just individual are over," he allegedly wrote. One passage from the manifesto reads, "I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty." "I never had the opportunity to have a family of my own," it reads. I'm terminating yours. Randy Quan, who became a lawyer in retirement, represented Dorner in front of the Board of Rights, a tribunal that ruled against Dorner at the time of his dismissal, LAPD Capt. William Hayes told The Associated Press Wednesday night. According to documents from a court of appeals hearing in October 2011, Dorner was fired from the LAPD after he made a complaint against his field-training officer, Sgt. Teresa Evans, saying in the course of an arrest she had kicked a suspect who was a schizophrenic with severe dementia. After an investigation, Dorner was fired for making false statements. "We have strong cause to believe Dorner is armed and dangerous," Maggard said. Police say Dorner is 6-feet tall, and weighs 270 pounds. He has black hair and brown eyes. Meanwhile, Cal State-Fullerton is still mourning the loss of their beloved assistant coach. "There are really no words to convey the sadness that our program feels, that the young women who have had the privilege of working with such a bright and passionate woman," head coach Marcia Foster said earlier this week. After college, Quan coached at Lutheran University in Thousand Oaks and has spent the past two years as an assistant coach at Cal State-Fullerton. The university has posted a memorial page on its sports website dedicated to Quan. Lawrence was a business graduate who recently started working as a public-safety officer at USC.
