RMN was present at the infamous meeting at the Dallas home of Clint Murchison the night before JFK's assassination. Others said to have been there--where among other things, the $50,000 compensation for each of the shooters was affixed.--were H.L. Hunt and J. Edgar Hoover.
RMN was said to be on Dealey Plaza 11/22/63. RMN was a high muckety-muck paymaster in the CIA at the time (That is, he was authorized to draw from the black ops slush funds.) He was a precursor to Nicholas Deak.
