1. The Witnesses: because of the rules of evidence and confrontation clause everyone who might have evidence and testify at evidentiary hearings or trial gets listed, including the police officers who took statements and collected and tested evidence, which is why the nurse is there.
2. Regardless of the number of witnesses, felony investigations take time, particularly when something has to be tested by a lab. This could also literally be as simple as the ADA being behind.
3. Very possible they overcharged. Very possible it's a withdrawn consent issue. Very possible the witness listed is a friend who the victim talked to later and it'll be excluded. Very possible he pleas. It's still sickening almost regardless of what ultimately happens solely because it's at this point.
4. Innocent until proven guilty is a burden of proof maxim. We're free to disregard it outside of the courtroom for non-criminal purposes. The default should be to believe the victim in this circumstance. We have no evidence from TSJ other than a denial through his lawyer, and no evidence the victim is lying.
5. I agree with spark on the DIA. They've had 3 months to investigate and get ahead of this story. If their investigation concluded otherwise, they should be protecting their student-athlete now, and if it's just been a wait and see thing, they should at least have a statement crafted.
