The kidnapped 15-month-old son of a West German millionaire was found dead Tuesday, 10 days after he was seized during a bloody break-in at his parents' house in Eslohe, police said. The boy's 56-year-old grandmother was strangled in the Nov. 12 attempted robbery at the home of Christian Padberg, a wealthy building material trader. The intruder then fled with 15-month-old Patrick Padberg and later demanded several million marks ransom.
