| Brief Quote / Description of Testimony | The analyst never explained the finding in lab report of a PGM type foreign to victim. Instead, the analyst testified that 37% of the population shared Ollins’ type, without explaining that Ollins was not a secretor and could not have been the donor. Further, the PGM allele 1+ that was attributed to Ollins could have originated from the victim. As Dr. Edward Blake concluded in his report evaluating the case, the analyst “failed to state that her findings eliminated Larry and Calvin Ollins, Sa[u]nders, and Bradford unless there was another semen source who was an ABO type O secretor.” Dr. Edward Blake, Review of the Testimony of Pamela Fish, January 9, 2001. See Part II.A.1 for a description of the problem of masking and non-quantification and discussion of similar cases. The analyst testified that questioned hair was “similar” or “could have” originated from defendant. |
