Ngô Sĩ Liên
Some reports by Ngô Sĩ Liên, Phan Huy Chú and "Quốc sử quán" (National History School under Nguyễn Dynasty) also wrote that Trãi might be innocent in the death of the Emperor but not Lady Nguyễn Thị Lộ. Other scholars suggest that Lady Nguyễn Thị Lộ may have been an innocent victim of Nguyễn Thị Anh the emperor's wife. Other scholars suggest that the emperor became sick and died of natural causes.
