The players all said they didn't have sex with her, consensual or otherwise. A DNA match would be a massive blow to their creditibility.
I think we know one way or another within 24 hours. If there is a match, the DA isn't going to want to wait so that the matched players can possibly flee.

depends on what they've matched--if these girls were locked in the bathroom there could be lots of matches other than semen..but what do I know?
