My sister's purse was stolen containing the keys to our apartment and the car. A week or two later the car was stolen.
I have some suggestions. I think that you ought to change the locks to your apartment and your car first thing. Also notify the social security administration, the DMV, and your bank and credit card companies. Since this creep knows your address and soc sec #, you should contact the credit agencies in order to avoid identity theft. He could open credit cards in your name with your info, charge thousands of dollars and ruin your credit.
I'm sorry that this happened to you. It is such a pain in the neck to replace all those documents.
