He crushed the home while a child was inside the place. It may be a hair’s breath away from attempted murder. It is at the very least reckless endangerment. He needs the book thrown at him.
There are legal avenues open to a landlord that is trying to evict someone. You don’t need to burn down the apartment complex or destroy the trailer to kick someone out. If he had done it right he could have spent Thanksgiving with his family, and not been in jail.
