A man accused of masterminding the kidnapping of one of the richest men in America has been sentenced to 15 years in prison. Renaldo Rose has admitted that he and three other men used a shotgun and an air gun to kidnap Edward Lampert from a Greenwich, Connecticut, parking garage in January of 2003. According to Forbes magazine, Lampert -- of the hedge fund ESL Investments -- is worth about one-and-a-half billion dollars. Prosecutors say the kidnappers told Lampert they'd been hired to kill him for one million dollars, but that they'd give him the opportunity to buy his own life. Lampert escaped by convincing his captors that he needed to tap into ESL funds to pay them. The three other defendants in the case await sentencing.
