Tinkerer, I was on scene the morning after a fatal fire in a hotel room. My job was to 'make safe' the electrical.

This fire had been so intense that the couplings had melted off the EMT. Still, the point of origen was fairly clear; there was little left of the bed but the metal parts of the box springs. Chalk one up to smoking in bed.

This all aside, the adjuster from the insurance company was just determined to attribute the fire to 'electrical.' This was despite the scene having already been dissected by the crime-scene folks (there had also been some indication there might have been foul play).
