Princess Diana’s car crash from 1997 is believed to not have been an accident.

Two witnesses are convinced that the royal family and other forces might have been involved. Robin and Jack Firestone lived in a gated complex after the incident for fear that there could be reprisals.

“We still live in fear today because of what we saw and what we were told,” Robin said.

“I think the crash was a royal thing and other forces were involved… Something bad could still happen to us… There are enough nuts out there who may try to silence us,” Jack said.

But as time goes by, Robin said that their fears have also lessened. Back in the day, the Firestones wanted to submit their testimony after Princess Diana’s car accident but they were stopped by the French and British authorities from doing so because their story raised too many questions.

Robin claimed that he saw two dark cars that stopped in front of Princess Diana’s Mercedes Benz, which she believes is involved in the accident. Robin and Jack, alongside their son Brandon, entered the tunnel just minutes after the crash on Aug. 31.

The family was at the back of a taxi on their way to their hotel after going on a night-time cruise on the River Seine. Robin said that she could vividly remember two dark cars stopping in front of the Mercedes Benz.

“I could not understand why they were there. They looked at odds with what had happened… I saw those dark cars, and they must have entered ahead of Diana’s,” Robin said.

Robin also said that she wasn’t the only witness that saw the two dark cars, which were awkwardly parked. She said that the two vehicles had to be driving in front of Princess Diana’s car.

Princess Diana, her then-boyfriend Dodi Al Fayed, and her driver Henri Paul all died following the incident. Only the couple’s bodyguard, Trevor Rees-Jones, survived.
