WHAT evidence?
What evidence is left?
Nifong has no evidence but he has to come up with a timeline that puts all three players in the bathroom. He has a problem with Reade because of his alibi evidence. He does know the times that are related to Reade's alibi though so he's adjusted his timeline for them and condensed the non-rape from thity minutes to 5-10 minutes. That's all Reade's alibi allows for - if that. He would have had to have been on the phone while he was in the bathroom.
The thing is, he doesn't know what Collin's alibi is so he can't build his timeline around that yet.
