Unverifiable: Robin Firestone alleges that two dark cars which had stopped in front of Diana’s Mercedes S280 were involved in the crash.

The claim made by Robin Firestone cannot be verified due to a lack of sources available to support his claim. Princess Diana died in a car crash in Paris on 31 August 1997. The aftermath of the crash was witnessed by an American tourist couple, Robin and Jack Firestone. They spoke to Daily Express recently and expressed their anguish about the way investigation was conducted. Robin told that the two mysterious black cars they saw in the vicinity of the crash was never acknowledged officially, and might have been involved in the crash. However, we cannot objectively verify his statement due to a lack of sources available to support his claim.
