 Apart from the probability that it was obtained under torture, there is some doubt about the reliability of O'Collun's confession, since the Crown's interrogators, as was usual in treason cases, put pressure on the suspect to confess to what they wished to hear.It seems that at first O'Collun and Annias would confess only to a plot to kill "The Spaniard".This was undoubtedly Antonio Pérez, former Secretary of State to the King of Spain.
