1978: The Vatican Cover-Up That Fuelled a Poisoning Legend: the Death of Pope John Paul I
Pope John Paul I was found dead in his bed after just 33 days in office, the shortest papacy since 1605, with a religious devotional still in his hands. The Vatican initially claimed a priest had discovered the body; in truth it was a nun, Sister Vincenza, who found him, and officials lied about it out of embarrassment that a woman had entered the private papal quarters.
No autopsy was performed and the body was embalmed with unusual speed, feeding decades of speculation that he had been poisoned to stop him exposing corruption at the Vatican Bank. One theory even produced a mobster who claimed to have helped administer the poison. Later research drawing on confidential Vatican archives instead found a simpler explanation: a history of heart trouble, chest pains the night before his death, and no doctor ever called.
