Since 9/11 a lot of people holding sensitive posts, includingbankers, doctors and scientists have been found dead under mysterious circumstances.
In the report printed in the New York Times on November 27th, the FBI’s Memphis office distanced itself from the case saying that the available facts did not add up to a suspicion of foul play. I guess at the FBI it’s a perfectly everyday occurrence for a Harvard Professor to stop his rental car on a bridge in the middle of the night before he is supposed to leave for Iceland and just walk away into the Tennessee dark. Move along citizen, nothing to see. The professor’s colleagues expressed doubts about the official “suicide” explanation for his disappearance. (source)
