Buyer entered property before closing and made major alterations

[Matthew Kesner]

I have a property under contract. The buyers entered the property (without permission) and made major modifications to the house(before closing) ie. taking down walls, doors, stealing tools from the garage. Unfamiliar with this situation, I am looking for advise on how to make a concession in the contract to allow for the theft, unsure what happens if they back out and leave me a heavily altered house. Do I press criminal charges for B & E/theft, seek a real estate attorney or a criminal attorney. Any help in the right direction would be sincerely appreciated.
