I have been trying to find something on this today and have not had any luck. It seems rather strange that nothing can be found but then again I suppose given the height the levels of corruption it should not be a surprise.
I have been trying to find relevant articles and links about the case to post in a group on FB that has been created about Jesslyn Rich called JUSTICE FOR JESSLYN.
I have been wondering if these hearings were taped...

Have you tried finding any of the articles on Google? If there was taped recordings of it, I don't think they were ever released to the public due to the circumstances involved.

The only thing I have found is an article describing how Betty Thompson's supervisor was ordered to stand trial for forcing the forgery of Betty's signature on the documents that Betty mentioned. I have not been able to find out what became of that.
I had also tried to search C-Span just in case it was on there but no luck.
If I am able to find it I will surely post it as I am sure it is in the public domain.
