Hi Chris, you might check out the work of William Kelly, Larry Hancock and others in tracking down the Pathfinder operations, which involved shooting Castro with a high powered rifle as he drove through a slowed down section in an open jeep. One would presume they had a patsy handy to take the fall. http://jfkcountercoup.blogspot.com/2018/10/part-ii-pathfinder-at-npic-and-dealey.html https://larryhancock.wordpress.com/2013/11/19/corroboration/
More recently the has been good research on The Black Nine, an extremely secret Pathfinder sniper team that “disappeared” in mid to late 1963, ostensibly infiltrated into Cuba to assassinate Castro. But some think this sniper team was purposefully turned on JFK instead. https://larryhancock.wordpress.com/2019/04/20/wheaton-names-update/
Hope this helps,
Chris
