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 suggested that a woman in Chicago, who claimed to be his daughter, 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, and also said that she is "very opportunistic." 

"Michael did date Marqay's mother, but he believed he was not her father," a source close to Duncan's family told Radar Online. "He was in the hospital for 53 days, and she never once reached out or tried to talk to him then. It was the DAY he died that she started calling his mother saying 'I want what's mine' and trying to get money from her."

"Why wouldn't she have tried to visit him after he had his heart attack?" the source added. "Why didn't she try and reach out to him while he was alive? It all seems like she just wants money and didn't ever care about having a relationship with him."

FOX Chicago spoke with Ambrose, who claimed she hadn't talked to Duncan in eleven years and regrets they didn't resume a relationship.

"The only thing that really bothers me about him passing is that we didn't fix (it)," Ambrose told My Fox Chicago. "That's the only thing that I hate. I hate it but it doesn't bother me that I'm not mentioned."

Duncan stayed at a Los Angeles hospital until his death after he suffered a heart attack seven weeks prior.

On Tuesday, Sept. 4, a coroner confirmed that Duncan died of natural causes. Assistant Coroner Chief Ed Winter said the actor's personal physician signed off on the star's death as natural and added that his office does not disagree with the finding.

Duncan "never fully recovered" from his July 13 heart attack, a rep for his fiancée, Omarosa Manigault-Stallworth, told E! News.

Manigualt- Stallworth was a contestant on the reality show "The Apprentice."

"Manigault is grateful for all of your prayers and asks for privacy at this time," the rep added. 

Duncan recently starred in the FOX TV series "The Finder." The 6-foot-5, 300-pound actor, who was often called a "gentle giant" throughout his career, was well-known for his role in "The Green Mile" in 1999, which he was nominated an Academy Award for.
