September 1978–November 2017
1978–2017: controversy over the circumstances of his death
The pope died suddenly overnight on 28–29 September 1978 and no autopsy was performed. Conflicting early accounts of the discovery of his body fuelled poisoning and banking-conspiracy theories, without substantiated evidence. In 2017, a documentary investigation by Stefania Falasca, drawing on medical records and witness testimony, concluded that he died naturally of a heart attack.
