The news of the murder soon reached La Salle, and a telegraphic dispatch was sent to Ottawa for Sheriff Thorn, who arrived with a military force about 7 o'clock in the evening. These, with Mayor Campbell, of La Salle, and about one hundred citizens, started for the scene of the murder.--On arriving at the spot a number of individuals were discovered, scattered over the hills, some of whom were armed, though only a few assumed a threatening attitude. Being fired upon they stopped, and one returned the fire, and received, in return, two balls in his arm, and was then arrested. The Sheriff then visited the different shanties and arrested all, or nearly all, the men he could find, amounting to sixty or seventy, of which some thirty or forty were recognized as participators in the row, though none were of the supposed ringleaders, but these were subsequently arrested. The Sheriff left a portion of his force as a permanent guard; and the work being prosecuted by other parties, the vicinity, through out the winter, bore resemblance to a regular military encampment. Twelve were indicted as ringleaders in the affray, four of whom, Kren Brennan, James Terry, Michael Terry and Martin Ryan took a change of venue to Kane county, where they were convicted of murder, when a new trial was granted which resulted in a second conviction. By the clemency of Gov. Matteson their punishment was commuted to imprisonment in the penitentiary for life; and among the last of his official acts, a full pardon was granted. The executive interference caused great dissatisfaction, and upon the occasion of the Governor visiting La Salle, he was burnt in effigy. Six were convicted of manslaughter and sentenced to the penitentiary for one year and served out the term. The other two were not found.
