Dorner manhunt: Cabin not intentionally set on fire, sheriff says
February 13, 2013 | 4:37 pm

"We did not intentionally burn down that cabin to get Mr. Dorner out," Sheriff John McMahon told reporters at a news conference.

[Updated, 4:53 p.m. Feb. 13: He said that deputies fired conventional tear gas into the cabin and then used incendiary gas on the structure, which was first reported Wednesday by The Times. The cabin burned to the ground. Dorner is believed to have died inside.]
