I want to thank them for their bravery."
As the cabin in which Dorner was believed to have been holed up inside burned to the ground, Villaraigosa would not confirm nor comment on the fate of the man.
"I want to thank all of the law enforcement professionals who have, day and night, tried to bring Christopher Dorner to justice and obviously I'm not going to comment on what most of you have seen as I have because I'm not in a position to do that; that's for the representatives of the San Bernardino Sheriff's Department."

"There is a subject barricaded in a cabin and at this time that cabin is on fire," she said, later adding that fire crews won't go near the fire just yet, since it's believed there's an armed person inside.
"I know the subject stole a vehicle from the Big Bear area," she said, describing how the scene unfolded earlier. "He fled on foot not far from this cabin that he's in now. When he barricaded himself in the cabin, there was gunfire exchanged between the deputies—who were the first responders—and the suspect.
"The suspect has been described as looking similar to Christopher Dorner, and we have reason to believe that it is him," Bachman continued. "That is unconfirmed at this time, because we have not had any contact with him, except for the deputies that were engaged in gunfire with him."
Bachman said law enforcement personnel "are planning on a long night," as the area is considered an active crime scene.
"If this is Christopher Dorner here, he's now responsible for the murder of four people, and attempted murder of three others," she said.
"The entire area is surrounded by law enforcement personnel," she said. "As you know, there's been law enforcement here in the mountain communities from across Southern California, including the FBI, the U.S. Marshals; we have plenty of air support and we need to let them do their jobs, and bring this incident to a safe ending."
