There are a number of discrepancies in the various accounts of the event. According to Cortés himself, on 27 February 1525, he learned from a citizen of Tenochtitlan, Mexicalcingo, that Cuauhtémoc, Coanacoch (the ruler of Texcoco), and Tetlepanquetzal, the ruler of Tlacopan, were plotting his death. Cortés interrogated them until each confessed and then had Cuauhtémoc, Tetlepanquetzal, and another lord, Tlacatlec, hanged. Cortés wrote that the other lords would be too frightened to plot against him again, as they believed he had uncovered the plan through magic powers. Cortés's account is supported by the Historian Francisco López de Gómara.
