Twenty years after Princess Diana’s tragic death, the French ER doctor who first reached her in the Paris tunnel still remembers every second as if it were yesterday. Dr. Frédéric Mailliez, off-duty that night, rushed to the mangled Mercedes just seconds after the crash and found four victims—only Diana and one other were still alive. With his resuscitator in hand, he tried to help her breathe, gently reassuring the princess that an ambulance was on its way. “I hoped my words were the last she heard,” he told CBS, reflecting on the haunting memory that remains “printed” in his mind to this day.
