A private laboratory hired by the prosecution in the Duke lacrosse case failed to report that it found DNA from multiple males in the accuser's body and underwear, according to a defense motion filed today. The lab, DNA Security of Burlington, found that the DNA did not match the three defendants, their lacrosse teammates or anyone else who submitted their DNA to police, including the accuser's boyfriend. The new evidence emerged in thousands of documents handed over to the defense in October.
