Dewey’s speculation of who committed the murder shows how unusual Perry really is. When trying to figure out whom the culprit is Dewey examines the strange placement of the bodies before they were killed. He wonders why the mattress box was moved in front of the furnace and comes to the conclusion that it was done so to make Mr. Clutter more comfortable before he was killed. In first seeing a pillow neatly placed under Kenyon’s head Dewey thinks it was put there to make his head a larger target. But after consideration he found that, as it had been with the mattress box, the pillow was there to make the victim more comfortable. Dewey was right in that the killer, “Felt for them, even as he destroyed them, a certain twisted tenderness” (103). In this speculation Dewey was correct, Perry had sympathized with the Clutters before he snapped and killed them. He had tried to make them comfortable while he persuaded Dick not to kill them, but in the end it was at Perry’s hand that they died. Dewey found that these suspicious acts of kindness supported his, “Notion of a murderer now and again moved by considerate impulses” (103). But in reality Perry is the opposite of this notion. He is a considerate person now and again moved by impulses to murder. Dewey also comes to the conclusion that, “At least one of the murderers was emotionally involved with the victims” (103). Dewey’s assumptions seem justified because no murderer could feel that connected to someone, sympathize for them and then slit their throats unless this murderer had know the Clutters for a long time before they had decided to murder them. Although all of Dewey’s conclusions would seem correct to anyone just examining the facts, knowing Perry the reader knows that Dewey is mostly wrong. This shows that Perry is very unusual because it is so hard to contemplate that he could feel for the Clutters then at the next moment kill them. Dewey comes to the logical conclusions of what kind of a killer would have behaved in such a manner. Because Perry does not fit in the norm of how humans act, anyone who simply looks at the facts cannot come up with the real feelings he had the night of the murders.
