I guaran—damn—tee ya that this will turn out to be a self-serving fraud by the prof herself.

I agree. This sounds like a hoax. Columbia knows what is on the tape. If the court will not force Columbia to turn over the tape, then point out that Columbia knows who did it and is not telling, that there is no way to force them to tell, and that the case is therefore being closed as unsolvable. Then reassign the police resources for this case to important tasks.
