Was Mark McCandlish suicided because he was allegedly scheduled to testify to US Senate and reveal the truth

Why would anyone want to murder Mr. McCandlish? I do not know. But the details in the articles posted by Morningstar do point in a couple of directions:

(1) that underground "breakaway civilization" itself, anxious to keep its secrets, and

(2) another peculiar detail that is revealed in the article, namely, McCandlish's belief that he had been in contact with someone claiming to be "an extra-terrestrial among us" in a human "biosuit", in disguise as it were and reminiscent of the old science fiction television series "V" and its more recent remake, and

(3) McCandlish's statements that "telekinetic murder" (for want of a better expression) was not only possible but that had been carried out on North Korea's previous leader. What is odd to contemplate here is that the first of these alternatives is the one where there are the most publicly-known details. It's the last two that are of greater interest, and had McCandlish come into possession of details that tended to corroborate either, then there would be powerful motivation by the parties involved to keep those details secret; indeed, I've speculated many times about the second possibility, and the claims about the third have been echoed by other people.

Similar to what happened to

I'm reminded of another such "convenient" death, that of George De Mohrenschild, who also allegedly committed suicide by shotgun mere days before his scheduled appearance to the 1970s committee on assassinations, to testify about what he knew of the JFK assassination (which, if one digs long enough, may also have had a "UFO connection").
