Stockton firefighters released helmet camera footage of their firefighters battling a fire in a vacant building that was the scene of a previous fire. 

From response views to interior operations, the video shows the scene size up, fire attack and work crews did to open up the structure and find heavy fire in the attic.

Toward the end of the video, as a firefighter is overhauling in the attic, part of the roof collapses on the firefighter.
