Note more smoke is visible coming from the door and windows of the building. The main fire is on the other side of the theatre which is between this bar and the Restraunt where the fire was thought to have started. If you look to the rear of the fire engine you will see a large round aluminum vent in the wall, well earlier smoke was seen coming out of that vent by me.
It turns out once demolition started that there was one wall between the kitchen and the theatre inside the stucture that was just lumber and sheet rock with no bricks at all so at one time it was probably an open area or a large hall that was later walled in but they did not put in a brick wall. So when the fire breached that one wall it then was able to get into the theatre itself from the kitchen where it started. The wall looked to be about 15 to 20 ft wide.
