People often say they remember where they were the day they found out that Princess Diana had been killed in a car crash.
While there have been many theories about the reason behind her death, none are more chilling than this revelation by Dr. Richard Shepherd, who examined the Princess of Wales twice, as part of an official investigation into her death.
In a shocking new interview, one of the world's most eminent forensic pathologists has claimed that if Diana had been wearing her seat belt, she would have lived.
Speaking with The Daily Mail, Dr Shepherd said, "I wish I could say she would have died whatever happened, but the fact is, if she had worn her seat belt she would have been here for Prince William and Harry's weddings."
"She would have walked away with a black eye or maybe a broken arm, but nothing more."
According to Dr. Shepherd, the car in which Diana and her boyfriend Dodi Fayed had been in that fateful August evening had been "hurtling forward with the weight of one and a half elephants, and the human body is not designed to suffer those forces."
There were many other questions which arose from the Princess of Wales' death and many were asked to the doctor himself.
"People asked: 'Was she beautiful?' 'Was she peaceful?' 'Was she pregnant?' he said.
"I always made sure I never said anything — in all the cases of public interest I was involved with — that hadn't already appeared in the press.
"Pathologically there was no evidence that Princess Diana was pregnant, but some women say they know they're pregnant from the moment of conception."
Dr. Shepherd, who has dealt with many high-profile deaths in his lengthy career, also recalled that there was no 'enhancement of the procedures and protocols' for celebrities or royals - the only difference is that more senior police are present.
After another case which saw the public vilify the police force's failure to arrest a murderer, "it really began to seem that demands for an inquiry into the Met's investigative failures would be met."
"I was delighted by the strong move for change which forced a rethink in official and police culture."
On the anniversary of her untimely death in 2017, Diana's sons celebrated their mother's legacy.
In a series of intimate, hard and moving interviews released last year for the 20th anniversary of her death, the royals shared stunning details about the woman behind the People's Princess, in a documentary: Diana Our Mother: Her Life and Legacy.
The unprecedented access to the boys' hearts and memories was summed up by Prince William perfectly.
"Her 20th anniversary year feels like a good time to remember all the good things about her and hopefully provide maybe a different side others haven't seen before."
"She was our mum, she still is our mum you know and of course as a son I would say she is the best mum in the world."
