Taylor is on trial for crimes against humanity and prosecutors say the blood of tens of thousands of people are on his hands. He is accused of orchestrating bloody massacres to ensure a personal profit from the Sierra Leone diamond trade, which has become known in the movies and the press as "blood diamonds."
Now on trial in the Hague, Taylor angrily denies any wrongdoing.
But in a bizarre twist, prosecutors say they can directly tie Taylor to the blood diamonds through fashion model Naomi Campbell based on what one of Campbell's famous friends told them.
"You don't forget when a girlfriend tells you she was given a huge diamond in the middle of the night," said actress Mia Farrow.
Farrow is a human rights activist and says the incident happened in 1997 in South Africa after an evening at the home of Nelson Mandela. The event was also attended by Taylor.
"She said during the night some men had knocked at her and they were reps of President Charles Taylor and they had given her a huge diamond and we were like, 'Oh my gosh,'" said Farrow.
Prosecutors say that Farrow's account is important because it is one of the few that ties Taylor directly to possession of blood diamonds. Prosecutors wanted Naomi Campbell's help in the case but they say she has refused to cooperate.
"You received a diamond?" asked an ABC News producer during an interview.
"I did not receive a diamond and I'm not going to speak about that, thank you, and I'm not here for that," responded Campbell.
Campbell became upset when asked during an interview why she wouldn't cooperate with prosecutors.
"We've been told you didn't help the prosecution in this very important case," said the producer.
"Thank you very much. Goodbye," said Campbell who then took a swing at one of the ABC News cameras.
Mia Farrow says it's not too late for her friend Naomi Campbell to step up and tell the truth.
