The Johnson County attorney began to gather evidence for the case and the details of the WSGA's plan emerged. Canton's gripsack was found to contain a list of seventy alleged rustlers who were to be shot or hanged, a list of ranch houses the invaders had burned, and a contract to pay each Texan five dollars a day plus a bonus of $50 for each person killed. The invaders' plans reportedly included eventually murdering people as far away as Casper and Douglas. "The Times" reported on April 23 that "the evidence is said to implicate more than twenty prominent stockmen of Cheyenne whose names have not been mentioned heretofore, also several wealthy stockmen of Omaha, as well as to compromise men high in authority in the State of Wyoming. They will all be charged with aiding and abetting the invasion, and warrants will be issued for the arrest of all of them."
