>>”Once they accept what Frank Sheeran said, the FBI completely loses jurisdiction of the case,” Brandt said. “They would have no reason to hold onto the file. It’s not a kidnapping. The murder occurred in the city of Detroit. Nobody crossed a state line. It’s actually a Detroit homicide.”<<
This part made me files this as unlikely conspiracy theory - a homicide as part of union corruption/ organized crime/ RICO etc would absolutely be FBI business.
If Tony Soprano killed somebody does this guy really think the FBI would have to stay out of it and publish all the details they know just because the body didn’t cross state lines?
He's not real. He's a tv character.
And, RICO didn't exist back then.
