Authorities said Dorner was seen several times in the San Diego area shortly after the couple's deaths, before he moved back north to the Los Angeles area. After several further sightings, police found their next clue in the area of Big Bear Lake when Dorner's pickup truck was found completely burned out.
Five days later, police say Dorner stole a vehicle in the San Bernardino Mountains along California Highway 38. A short time later, the vehicle was located by police and Dorner fled into the forest -- where he barricaded himself in a cabin. A subsequent shootout between Dorner and authorities left two sheriff's deputies wounded. One of them ultimately died from his wounds.
Finally on Tuesday, police surrounded the cabin and engaged Dorner in yet another firefight before the cabin caught fire. Dorner was not seen escaping the burning cabin, and the human remains were found later in the ashes. A medical examiner has not yet determined that the remains belong to Dorner, but authorities firmly believe they are indeed his.
Dorner was born in New York but raised in Los Angeles County. According to his online manifesto, Dorner was bullied as a child and he claims he was often the victim of racism. He attended Southern Utah University, where he graduated in 2001 with a major in political science and a minor in psychology. In 2005, he started the process of becoming a Los Angeles Police officer and, despite regular disciplinary issues, he received his badge in 2006.
Dorner was terminated by the police force in 2009 for allegedly filing a false police report -- in which he alleged that his female partner at the time repeatedly kicked a suspect being placed under arrest. A review board found those claims to be false and Dorner was fired. Dorner claimed in his long, rambling manifesto that he was the victim of racism and that the LAPD punished him for being a "whistleblower."
Dorner alluded to the killings in the manifesto -- saying "when the truth comes out, the killing stops" -- along with many other, sometimes off-topic issues.
"It's kind of sad I won't be around to view and enjoy The Hangover III," Dorner wrote, referring to the upcoming goofball theatrical comedy. "(Director) Todd Phillips, don't make anymore Hangovers after the third. (It) takes away the originality of the foundation."MORE:
