On Feb. 14, 2013, authorities announced that accused murderer Christopher Dorner was dead. The charred remains removed from a burned out cabin in the Big Bear region of Calif. were positively identified as the former Los Angeles Police Dept. officer, reports KABC 7.
In addition, documents have been released that indicate Dorner gathered information about his first two victims, before ambushing them in their vehicle, according to the Orange County Register.
KABC reports Dorner was identified through the use of dental records during an autopsy.
On Tuesday, a mountain cabin where Dorner was believed to be hiding out went up in flames after law enforcement shot tear gas canisters into the structure.
Prior to the fire, Dorner engaged in a shootout with authorities, killing Dep. Jeremiah Mackay, 35, in the process.
MacKay was the fourth person believed to have been killed by Dorner since Feb. 3, when Monica Quan and her fiancé Keith Lawrence were found dead as they sat in Lawrence's car in the parking lot of their condo complex in Irvine.
The Register reports that documents show Dorner was gathering information on the young couple, as well as Quan’s family.
In a manifesto he released prior to the killings, he blamed Quan’s father, Randy Quan, for the end of his law enforcement career. Randy Quan, a ret. LAPD officer, was also an attorney and represented Dorner at a disciplinary hearing after the former Navy Reservist was accused of making false statements about a field officer he claimed kicked a mentally ill arrestee.
Prior to his death, Dorner was charged with killing Riverside Police Officer Michael Crain, 34, who he shot on Feb. 7 after encountering Crain's police cruiser.
