Michael Clarke Duncan's untimely death has led to an outpour of condolences from his colleagues in Hollywood to his hometown of Chicago. However, shortly after the announcement that his cause of death was from natural causes, a new report suggests that a woman in Chicago who claims to be his daughter has reached out to Duncan's family in an extortion plot to get inheritance from his estate. Chicago resident Marquea Ambrose reached out to Clarke's family the day he died on Monday, Sept. 3. Sources close to Duncan's family confirmed that Ambrose called Duncan's 93-year-old mother on the day he died and consider her "very opportunistic."
