Smith admitted to cutting the throat Mr. Clutter and to shoot both Mr. Clutter and Kenyon Clutter in the head with a shotgun at close range. “The man would have died anyway, I know that, but I couldn’t leave him like he was. I told to hold the flashlight, focus it. Then I aimed the gun. The room just exploded (244).’’ He didn’t just cut Mr. Clutter throat but blasted him with a shotgun, it describes the atrocity of the “cold blood” crime. Perry smith is the central character of the book and attracted my attention on his trajectory toward his death. The author described in the book him as a “strange, psychopathic mixture of vicious killer and compionate protector” by the way he kill his victims.
