The body of a man who had been killed by bullets was found in the river, and there was a small key tag with the name "Bouthilette, Beauce, P.Q." on it. This gave the Police a clue, and it was followed with characteristic energy and skill. A web of circumstantial evidence had again to be woven. Later on another body was found and Surgeons Madore and Thompson were satisfied that another death by violence had occurred. The body corresponded with the description given of Guy Beaudien. Constable Burns, of the Dawson Division, who could speak French like a native, haunted the mines and creeks in plain clothes, unearthed Fournier, who was identified by one Mack, who had seen him at White Horse, as one of the men in boat 3744. Detective Constable Welsh, Sergeant Smith, Corporal Piper, Constables Burke and Falconer with others were on the scent. Welsh went to Skagway and found the sailing list of the boat _Amur_ on which the murdered men had come from Seattle. To that point and others he went, and then acting on information from Constable Burns, who had combed the French Colony for evidence, Welsh went on through six different States and finally caught and arrested La Belle in Nevada. La Belle said enough to indicate the whereabouts of the murder event and Welsh wired this information. Corporal Piper and Constable Woodill and the Dawson photographer went, located the "Murder Island," gathered some incriminating articles and took photographs from every angle. Then the work went on and the Police accumulated such an unbreakable chain-mail web of evidence starting with a man who had come with the murdered men from Montreal to White Horse, continuing with others who had seen all the parties on boat 3744 and then with men who had seen articles and money on La Belle and Fournier which they knew to have been the property of the murdered parties, that these cold-blooded monsters practically confessed, each throwing the blame on the other. They were committed for trial, found guilty by judge and jury, and paid the extreme penalty for their horrible crime.
