Christopher Dorner's last stand brings cabin inferno, single shot Christopher Dorner. Handout LOS ANGELES, Feb. 12 (UPI) -- A California mountain cabin where fugitive murder suspect Christopher Dorner was believed holed up after a deadly gun battle went up in flames Tuesday. KABC-TV, Los Angeles, reported once the fire ignited, a single shot was heard inside the cabin. There was no word on the status of Dorner, the ex-Los Angeles police officer wanted for four slayings, including one San Bernardino sheriff's deputy killed in a gun battle just before taking refuge in the cabin. The Los Angeles Times said its law enforcement sources said one of two deputies wounded in the shootout was pronounced dead after being airlifted to Loma Linda University Medical Center. The condition of the second deputy was not immediately known, the newspaper said. A Los Angeles Times source said Dorner, also wanted in the killing of three people and wounding of two other police officers, had broken into another cabin in the Big Bear area and allegedly tied up a couple he held hostage until Tuesday morning when he left. Fish and Wildlife officers, on the alert for a white pickup truck, spotted Dorner driving one and gave chase, the newspaper's source said. Dorner crashed the truck and allegedly exchanged shots with the officers before entering another cabin, which U.S. marshals said was near Mentone, where dozens of officers converged. The Times source said one San Bernardino County deputy was hit as Dorner shot from the cabin and a second was injured when Dorner went out the back, set off a smoke bomb and shot again in an apparent attempt to escape. Dorner was driven back inside, the source said. Hundreds of rounds were fired during the exchange with Dorner, the Times said. "There are deputies everywhere on the ground and on foot," Cindy Bachman, a sheriff's spokeswoman, told the Times. Big Bear Lake Mayor Jay Obernolte told CNN "it's only a matter of time" before Dorner is apprehended. "We're certainly hoping he can be captured and subdued without any more loss of life," Obernolte said. He's certainly not the kind of tourist we want up here. The incident occurred in an area that has been the focus of a massive search for Dorner, 33, who also is a former Navy marksman.
