CAIRO (dpa) – A 41-year-old man who admitted abducting and killing three boys since 1992 was sentenced Monday to life imprisonment with a recommendation against parole by a German court. Martin N, whose surname was withheld under privacy guidelines, was a serial sex attacker who wore a black mask and dressed in dark clothes, breaking into homes and holiday camps at night to abduct sleeping children, the court heard. One of the boys who survived such an attack remembered a detail years later that enabled police a year ago to arrest N, a youth worker with teacher qualifications, ending a two-decade old inquiry. He was convicted in Stade, south-west of Hamburg, of murdering a 13-year-old boy in 1992, an 8-year-old in 1995 and a 9-year-old in 2001. He admitted the killings in court and also conceded he had abducted and sexually abused other boys without killing them. Judges added a qualification to the life sentence that will make it difficult to parole him after 15 years, the usual minimum term in Germany to serve life, and ordered that if he ever wins parole, he continue to be detained for the sake of public safety. Those orders combine for the maximum detention term possible in Germany, making it conceivable that he may remain in jail until he dies, although future courts would still have authority to release him if psychologists were to rule he was no longer a menace.
