I'm not sure... IMO the news release just says that they've been doing tests to find DNA traces but it didn't help them identify a suspect. It does not say whether or not they found any unidentified DNA that could be the perp's.
Purely JMO, they didn't, because if they had a stranger's DNA in a strategic place they would have been more careful saying that they think it was not a stranger abduction.
(I am assuming that they have the DNA of everybody who was known to have been there.)[/QUOTE]
They have all of the DNA to those who are sitting in jail. From what i understand, LE takes your DNA and enters it into a database, so IF there was DNA in the MH found by LE, that matched Tommy or Joe, or Timmy, or someone other than Ron, Misty, HaLeigh and Jr then more then likely there would have been an arrest re HaLeigh's case.
