As the 60th anniversary of John F. Kennedy’s death approaches, new information released about the crime of the 20th century has become scarce.

In 2022, I wrote about a letter, found among released National Archives documents and written by FBI Director J. Edgar Hoover in 1968, that confirms that someone was arrested in Chicago related to a potential plot to kill JFK three weeks before the assassination in Dallas.

That, to me, is a key part of this case. The official story blames Lee Harvey Oswald as the lone assassin. This letter shows that at least one other person was arrested by police in connection with an alleged plot on Kennedy’s life around the same time as Oswald was arrested.

This letter has only been mentioned by one other researcher, to my knowledge. Yet, it could be an important piece of the puzzle, lending official acknowledgement that there another arrestee that same month. In fact, there was likely not just a Chicago plot, but possibly others, including in Tampa and Miami. It’s unknown if the participants in these attempts knew of the others, but if they weren’t related, it sure was a big coincidence that they occurred in more cities than Dallas at about the same time.

You would think Dallas officials would have a vested interest in wanting this story out. It shows that the assassination could have happened in another city, though Dallas was more conservative and anti-Kennedy than most at that time.

His trip was canceled at the last moment due to what a former Secret Service…
