One of my relatives (now deceased) was convinced that Jackie shot JFK with a handgun concealed in her purse. Yes, yes, I know; you don't need to tell me all the reasons why this is absurd.
Well there is the conspiracy that the second shot came from a secret service agent discharging by mistake, kind of a slightly saner version of that? If the thrust of your relative's theory was that the second shot came from another direction, not that Jackie was in on it (and perhaps Lee Harvey Oswald was really Leo Stavros Onassis?)
