Officials with the county sheriff's office said further forensic work will determine whether Dorner's death was a suicide, the Los Angeles Times reported. Dorner's body was found Tuesday in a remote mountain cabin that had been set on fire during a standoff with police.
Dorner allegedly killed three people, including a police officer and the daughter of his lawyer, before heading into the mountains in San Bernardino County. He allegedly shot and killed a sheriff's deputy Tuesday at the mountain cabin.
Dorner was fired as a trainee officer in 2008 after reporting that another police officer had kicked a homeless man and posted an manifesto online.
The fire was started when deputies used "burners," heavy-duty tear gas grenades that tend to be hot and to start fires.
