It was not until June the 7th, in the closing days of the inquest, that Luke Dillon, one of the nine members of the Executive Committee of the Clan-na-Gael in America, and who had taken a leading and determined part in the movement to unravel the mystery which enshrouded the murder of Dr. Cronin, was called as a witness. Those who were in the court room when he ascended the stand, saw a man above the medium statue, broad shouldered, of well-knit figure, square cut face and well moulded features. His dark blonde hair receded slightly from his forehead; while a full blonde mustache of lighter hue shaded his firm compressed lips. His chin was square, indicating tremendous energy and great determination of character. His voice was full, resonant and well modulated, and he spoke fluently and yet in a measured way that indicated caution. In answer to the questions of the Coroner he said that he was a member of the Clan-na-Gael, but that there was nothing in the obligation which he had taken that conflicted with the laws of the United States. He went on to say that Dr. Cronin, shortly before his murder, had said to him that the personal ambition of Alexander Sullivan, to rule both in Ireland and American politics would be the cause of his (Cronin's) death, for he felt that the man had no more blood than a fish and would not hesitate to take his life. The witness related the circumstances connected with the meetings of the trial committee at Buffalo and New York, and the examination proceeded in this wise: "Can you give the jury any other reason why Alexander Sullivan should be an enemy of Dr. Cronin?" "I can give none except personal revenge." "Revenge for what?" "Because this man found him guilty of crime, of theft." "By this man you mean Dr. Cronin?" "Yes sir; and also because of treacherous conduct to members of the organization." "Do you believe, Mr. Dillon, that Dr. Cronin's opinion of Sullivan was correct?" "I do now. I used to think he exaggerated Sullivan's importance. I looked upon him then as only an ordinary villain. But Cronin looked upon him as a very dangerous man and a very able man." "At the time of the existence of this so-called Triangle, Sullivan, Boland and Feeley, do you know of their betraying any members of the order?" After a long pause the witness replied: "No; I believe men have been betrayed." "Could these men whom you believe to have been betrayed, have been betrayed without the knowledge of the Executive?" "No, they could not otherwise be betrayed." "And men were betrayed?" "I believe so." "They were not known to anybody outside of the Triangle?" "They were not supposed to be known." "If known, where would those outside receive their information from?" "The executive; the Triangle and Executive were the same thing." "At that time who were the Executive?"
