A screenshot showing a cabin on fire near Big Bear where police surrounded a man they believe to be murder suspect Christopher Dorner following two gun battles on Feb. 12, 2013. A deputy was killed in one of the battles.

During the stand off with Christopher Dorner, police used what they call 'burners', or a type of tear gas grenade. Use of the grenades quickly started a fire, which engulfed the cabin and ended the standoff with Dorner.
