In life, it was Princess Diana's vibrancy and glamour that captured the world's attention. Today, it is the mystery surrounding her death. Correspondent Erin Moriarty reports. "She was convinced she was going to be killed," says Diana's old friend, Argentinean businessman Roberto Deverik, who recalls Diana often speaking of murderous plots against her. "She said, 'When it's not convenient anymore, I will-- they will blow me in a car or in a helicopter.'" The questions and puzzles remain nearly seven years after Diana's tragic death in a Paris tunnel. Billionaire Mohamed Al Fayed has relentlessly accused the British government of orchestrating the death of Princess Diana, and his son, Dodi. Al Fayed, who has refused numerous requests to talk to 48 Hours, believes that his son and Diana were killed in order to prevent the princess from marrying his son, a Muslim, and having his child. Conspiracy theories continued because the details of the French probe into the accident were never made public. But 48 Hours has obtained a report produced by the French government that was never made public until now. The report contains thousands of pages of confidential police documents, scientific analysis and images that tell what really happened to Princess Diana, beginning with the night she died.
