The Invaders continued to shoot at the cabin while others managed to set it on fire. Nate Champion signed his journal entry and put it in his pocket before running from the back door with a six-shooter in one hand and either a knife or a rifle in the other. As he emerged, the Invaders shot him dead. The killers pinned a note on Champion's bullet-riddled chest that read, "Cattle Thieves Beware". Jack Flagg, who after escaping his pursuers, rode to Buffalo where he reported Champion's dilemma to the townsfolk. Sheriff Angus then raised a posse of 200 men over the next 24 hours and set out for the KC on Sunday night, April 10.
