With many conspiracy theories swirling about whether the crash was really an accident or perhaps an elaborate assassination, Shepherd says the simple fact is that the princess would have survived the crash had she taken a basic safety precaution.

As for the alleged motivation for a possible assassination, Shepherd was asked if there was any chance she could have been carrying a baby at the time of her death; was Princess Diana really pregnant when she died?
‘I’ve seen no evidence,’ Shepherd says. ‘I’ve seen all of the medical and pathologic information, and I’ve seen absolutely nothing to support that she was pregnant.’
