Authorities: Dorner died from gunshot wound to head

Autopsy results on Christopher Dorner, the renegade former Los Angeles cop who authorities said killed four people and wounded three others, show he died from a single gunshot wound to the head.

Cpt. Kevin Lacy, the San Bernardino County, California, coroner, reported the results and said that authorities have not yet ruled on Dorner's manner of death.

However, information collected so far seems to suggest he took his own life.

"While we're still compiling the information and putting our reports together, the information that we have right now seems to indicate that the wound that took Christopher Dorner's life was self-inflicted," Lacy said.

The announcement came three days after a shootout, standoff and fire at a cabin in the mountains east of Los Angeles. Dorner's remains were identified during the autopsy through dental records.

Dorner was fired from the Los Angeles Police Department in 2009 for falsely accusing his training officer of kicking a subdued suspect. After unsuccessfully challenging his dismissal in court, police say, he launched a campaign of guerrilla warfare against the LAPD, targeting numerous officers involved in his case and their families.

Dorner was cornered and died Tuesday afternoon in the San Bernardino Mountains, about 100 miles east of the city he had once sworn to protect and serve.

The 33-year-old former Navy officer holed up in the cabin after a shootout with law enforcement that left a sheriff's deputy dead and another wounded, San Bernardino Sheriff John McMahon said.

The cabin caught fire when police shot tear gas canisters into it, McMahon told reporters Wednesday.
