Model jury instruction

 In this case, you heard expert testimony about inconclusive DNA testing.

Where DNA results are deemed inconclusive, the results provide no information whatsoever as to the source of the DNA. Therefore, inconclusive results may not be considered for any identification purpose. Inconclusive DNA results may be considered only if there is a suggestion that the Commonwealth failed to adequately investigate the crime.
