Brief Quote / Description of Testimony

The analyst testified that Gregory’s hair and the questioned hairs shared a set of rare characteristics. The analyst testified: “A. I told you, there is no statistics on this. I can tell you this is the first time I have ever had a negroid origin hair that has not had a medulla in it. Q. What percentage of people have ovoid bodies in them?A. This is probably the first time I have ever seen an ovoid body in a human hair. I have seen them in cattle hair before.” The analyst also testified that the ovoid bodies were “an unusual characteristic” and that the hairs “more than likely” belonged to defendant. The analyst also testified that five hairs found in the pantyhose mask came from an African American and matched Gregory’s, but failed to disclose that at least one of the two additional hairs didn’t match his. See Part II.B.2 and Part II.F.1 for discussion of this case.
