People are so desperate financially they're torching their own homes.
Burnin down the house
Note to people considering this. It won't work. Not only would you have to pay the deductable on the insurance, you'll still have to pay for a rebuild assuming you got away with it (unlikely). When you get caught and the insurance company doesn't pay you're stuck with no house, maybe jail time, legal fees and a mortgage you still have to pay. And I'd guess the mortgage co would call the loan.
