Brief Quote / Description of Testimony

The analyst testified: “A. My opinion is that the teeth that are represented to me as being Ray Krone’s teeth did cause the injury patterns that we call bite marks. Q. And how certain are you of your opinion? A. I’m certain. It’s a very good match.” Claims that bite mark comparison “has all the veracity, all of the strength that a fingerprint would have.” The defense also never learned that FBI expert Skip Sperber had examined the bite marks before Rawson, and concluded, “It could not have been clearer. . . Ray Krone had two higher teeth than his incisors that would have marked when he bit. Those weren’t there in the evidence.” See Part II.D. for a discussion of this case.
