I don't know what state you are in. In California.. even if you unkowingly purchase any item that is stolen, then you can go to jail for buying stolen property. You should try contacting the 'owner' again. Give the same option that she gave the dishonest person, and make a contract with her. You should get an attorney. Find one that specializes in livestock or horses. You could even bring up your childs condition to get a sympathy vote in your favor. Its a shame that there are so many dishonest people out there. It just makes it harder for us honest people.
