You must try to locate your husband. Send letters, return receipts requested, to his last known address, his relatives and friends, his last known employer. Contact the Motor Vehicle Administration to obtain a non-certified record that will list his ZIP code and any vehicle accidents he had in the past three years, which may help you track him down if he stayed in Maryland. Try anything else you can think of, such as an ex-girlfriend who has a few things she would like to say to him, too. Keep copies of every letter or record.
