(Reuters) - A U.S. Air Force deserter who has lived secretly in Sweden since 1984 has revealed his identity and contacted his family in the United States who were overwhelmed to hear he was still alive, a Swedish newspaper reported at the weekend. Dagens Nyheter said David Hemler had deserted aged 21 while serving at a U.S. Air Force base in Germany, after getting involved with a pacifist church and becoming disillusioned with the policies of former President Ronald Reagan.
