I've never heard of a medical examiner refusing a request from another medical professional to observe an autopsy. Many in the profession commented on that, and none of those commenting had ever heard of it either. I wonder how much he was paid to sign his name to that autopsy report.
Convenient, isn't it?
I believe Judge Greer denied the request for Cyril Wecht to observe the autopsy. Remember that Greer was the control mechanism the entire way.
