Greineder based solely on peaks above 100 RFUs. 'Tr. (9/13/06) /79-80. According to Dr. Eisenberg, Murphy is wrong. Virtually all. of the peaks relied upon by Cellmark to associate Dirk Greineder with the DNA recovered from the key three pieces of evidence were less than 100 RFUs. E. 685-686. With respect to the right-hand work glove specifically mentioned by Murphy, Dr. Eisenberg reviewed Cellmark's results locus-by-locus, concluding that "the only scientifically justifiable conclusion that can be reported is that Mabel Greineder must not be excluded as a potential contributor.. .'I and that the results over 100 RFUs do not implicate Dirk Greineder at all.. _A. 686-689. Murphy's third excuse was that such a motion would give the Commonwealth and its witnesses a helpful preview of the defense Murphy was planning to spring at trial. Yet, he failed to challenge the scientific reliability of Cellmark's testing before the jury. In cross-examining Dr. Cotton, Murphy did not ask her about Cellmark's lack .of validation studies for calling allelic peaks and DNA mixtures at less than 100 RFUs, its lack of specific criteria for lowering the RFU threshold from 100 to 40, its lack of substrate controls, or its flawed statistical analysis. Accordingly, filing a Lanisan motion challenging the admissibility of Cellmark's DNA test results would not have revealed Murphy' 6 trial strategy. 50

In any event, if filing such a motion would have led to the exclusion of Cellmark's test results, any clues about how defense counsel was planning to combat those results at trial would be rendered academic. Fourth, Murphytestified that a successful motion to exclude Cellmark's allelic calls under 100 RFUs would have undermined his strategy of suggesting that a third person was present at the scene of Ms. Greineder's death. Indeed, Murphy opined, the exclusion of such allelic calls would have "largely eliminated the stranger DNA argument. . , ." E. (9/13/06) /79. There are several critical flaws in Murphy's analysis. As Dr. Eisenberg pointed out, the defense failed at trial to identify a significant number of "stranger alleles" on any of the three key items of evidence. Only one such allele under 100 RFUs was identified on each item. A. 690. Moreover, as Murphy conceded, z. (9/13/06)/87, the defense could have presented its "stranger allele" argument based entirely upon peaka found on Ms. Greineder' s blue gloves, all in excess of 100 RFUs. On any rational. assessment of the case, Murphy's planned "stranger allele" defense, relying upon a smattering of alleles to suggest that a third person may have been present at the scene, paled in comparison to highly-incriminating evidence linking Greineder's DNA to 51
