Just look at those cross braces that supported the upper loft area. They are still standing but the upper 3/4 inch plywood is gone. You can even see the wood against the walls is brown. This was created by Accelerants. Probably a thinner like Toluene or Zylene. They will fume up a good cloud once sprayed all over and light hot. Throw in some lacquer thinner and you are there. There was a time I was afraid of these pricks, not anymore
