If you compare this with the article of a couple of days ago it seems this is the first time they've specified that the DNA on the two towels from both Evans and Zash was semen. As of the prior article they only described Zash as being such.

"Another specimen matched to Evans was recovered from a towel found in a hallway near Evans' room and the second bathroom in the house. The towel also contained DNA from another person, and SBI testing has conclusively determined that the second specimen did not match the accuser or the 46 members of the lacrosse team who submitted DNA samples, Sutton said."
Thanks to both of you! Having a tough time keeping up with all the details, guess I either need to buy the Program, or get John Madden to do the Xs & Os for me! :)
