I'm guessing there was a loose end that needed to be tied up.
says he committed suicide
On September 17, 1976, the CIA requested that the FBI locate Mohrenschildt, because he had "attempted to get in touch with the CIA Director."[55] On September 5, 1976, Mohrenschildt had written a letter to the Director of the Central Intelligence Agency, George H. W. Bush, asking for his assistance. He was acquainted with the Bush family; George H.W. Bush had roomed with Mohrenschildt's nephew, Edward G. Hooker, at Phillips Academy in Andover, Massachusetts.[56] The letter said:
You will excuse this hand-written letter. Maybe you will be able to bring a solution to the hopeless situation I find myself in. My wife and I find ourselves surrounded by some vigilantes; our phone bugged; and we are being followed everywhere. Either FBI is involved in this or they do not want to accept my complaints. We are driven to insanity by the situation. I have been behaving like a damn fool ever since my daughter Nadya died from [cystic fibrosis] over three years ago. I tried to write, stupidly and unsuccessfully, about Lee H Oswald and must have angered a lot of people I do not know. But to punish an elderly man like myself and my highly nervous and sick wife is really too much. Could you do something to remove the net around us? This will be my last request for help and I will not annoy you any more. Good luck in your important job. Thank you so much.[57][58]
He knew they were watching him. Of course they made it look like a suicide. That's one of the oldest tricks in the book.
who killed him then? Are bush family the good guys then?
The Illuminati. And who knows at this point. ---
