Dr. Frederic Mailliez told the inquest jury he saw the car carrying the Princess of Wales, and her boyfriend, Dodi Fayed, wrecked while he was driving down the Paris road where the crash occurred Aug. 31, 1997, The Daily Telegraph reported Tuesday.
He said he found Diana slumped in the rear footwell of the wrecked Mercedes, but did not recognize her as the princess.
"She was alive," he told the inquest into Diana's death. "She was moaning, she was breathing but she was really weak, I would say unconscious and weak."
Richard Keen, an attorney for the family of Diana's driver, Henri Paul, asked Mailliez during his cross-examination: "Do you remember saying that you thought the lady you had treated would survive?"
"Yes, I said that," the doctor answered. However, he said he was not aware of the extent of Diana's internal injuries at the time he made the statement.
