Two firefighters responding to a fire at a senior living complex in southern California were shot, one of them fatally. When firefighters responded to the early morning alarm, they say windows were blown out and a sprinkler was activated. After putting out the fire they continued to investigate reports of an explosion and a smell of gasoline. That's when authorities say the two firefighters were shot.
