Was Brian Wells Murder Investigation Stopped To Protect Ray Gricar From Obstruction Charges?

   If murder charges would have been filed in the Brian Wells investigation concerning Marjorie Diehl and Bill Rothstein in the Pizza Bomber Bank robbery case, Ray Gricar would have been indicted for obstruction of justice. Other law enforcement officers would have been indicted also. I know that Gina Haspel, the present head of the CIA agency in the U.S. government would also be indicted. 
    With that in mind it seems that Ray Gricar ran off before any charges were filed against him, fearing that FBI agent Clark might obtain information that would be used to indict him. 
  Following, is some of the information withheld from the FBI investigation. Let me say that if Gricar and others would have come forth with information concerning the case in 2003 there would have been charges filed for the murder of Brian Wells. Here is some of the information that was withheld:
1. Ray Gricar saw a collar like the one used in the killing of Brian Wells, while he was at a house in Erie with Marjorie Diehl, Bill Rothstein, Brian Wells, Myself, Gina Haspel and Brian Wells girlfriend. The collar was in plain view. It was setting on the coffee table in the front room of the house. You couldn't miss it. The meeting was at least a week before the bank heist. 
   Picture:  

2. Ray Gricar knew that Brian Wells was associated with Marjorie Diehl and Bill Rothstein.
3. Gina Haspel and 4 or 5 police officers saw Brian Wells at the Country Fair store just before he drove the managers car to the bank. Brian did not drive his car to the bank that day. He drove a car that was parked in the back of the pizza restaurant. It was a light color or white sedan. Brian's car was blue green or a darker color. You can see the car plainly in the documentary. https://en.wikipedia.org/wiki/ Evil_Genius_(TV_series)
   No one ever mentioned the car that Brian actually drove to the bank that day. After the robbery, Brian left the bank and left in his car. 
4. Brian Wells delivered the pizzas that day to people at the store across the street from the bank. He never went out to the television station tower. That story was made up. 
    He was not wearing a bomb collar when he met Gina Haspel at the store. Gina Haspel was also at the bank during the robbery. She came to the bank about two minutes after Brian left the car to walk to the front of the bank. In the diagram I said the car he was driving was parked at the side of the bank but I was mistaken. The car that I mentioned was the woman's car that worked at the pizza place where he worked. As far as I remember, that day was the first time he was allowed to deliver the pizzas in that car. 
    
   Was a murder investigation put off to protect certain people who withheld evidence? It sure seems that way. 

   I wanted to add that I think Ray Gricar just went into hiding. https://en.wikipedia.org/wiki/Ray_Gricar
