Updated at 11:12 p.m. ET: Despite an earlier report, CNN reported on television that Los Angeles police say that the cabin is too hot to search, and it might be days before a body that would be found in there could be confirmed as Dorner's.
Updated at 10:30 p.m. ET: CNN reported on television that Dorner is dead, and has this update on its website.
Updated at 7:46 p.m. ET: CNN reports that one officer has been killed and the cabin where Dorner was believed to be barricaded is in flames.
A person believed to be triple-murder suspect Chrisopher Dorner reportedly has been involved in a shootout with police in the Big Bear, Calif., region, and police are searching for him in the area, according to CBS Los Angeles, which is running a live video stream of the standoff.
In a separate report, an officer told the Associated Press that Dorner may have committed a residential burglary of a cabin and had tied up a couple inside. One person was able to get away and make a call. Authorities responded to the location and gave chase when Dorner fled in a stolen car. Gunfire was exchanged.
According to San Bernardino County sheriff's spokesman Cindy Bachman, authorities were investigating a stolen vehicle by a man who looks like Dorner. It is believed that Dorner may have crashed the stolen vehicle and was on foot when shots were fired.
The area is in the Big Bear region where a search for Dorner has been under way since his pickup truck was found there Thursday.
Authorities earlier said the search in Big Bear will continue until Dorner is caught, or it has been determined that he is no longer on the mountain. Big Bear Lake-area residents with surveillance cameras on their property were asked to check if they captured footage of the suspect.
