I don't think he has any DNA matches that help his case.
Dave's match on a towel doesn't surprise me - he lives there. And the partial match on a fingernail doesn't advance things either. His lawyers said he handled it and it was in his trash can with his dental floss etc.
The only DNA from Precious that I'm aware of is from her boyfriend.
He has Matt Z.'s DNA on the floor of a bathroom but he has cleared Matt Z.
I think the DNA is exculpatory for the players.
The DNA in this case is not exculpatory. It is neither incriminating to the people charged But it had nothing to do with the other discussion I was having which I guess is why it was introduced.
