Yep. I think the defense needs to track down the people who had contact with the accuser at Durham Access and interview them for themselves. I'm sure they are because it's obvious the police have no intention of doing it.
And it sounds like any report they get will be a very short version of the story. Maybe a little more than a blank page but not much.
They should interview everyone who was there that night. In fact, they should have done it long before now and locked down their stories.
