However, after blood was found on the knife, Byers stated that he had used it only once, to cut deer meat. When told the blood matched both his and Chris' blood type, Byers said he had no idea how that blood might have gotten on the knife. During interrogation, West Memphis police suggested to Byers that he might have left the knife out accidentally, and Byers agreed with this.[1] Byers later stated that he may have cut his thumb.
