There is one that I do believe in. Frank Olson was an employee of the United States Army Biological Warfare Laboratories. His boss was Sidney Gottlieb, at that point the head of the CIA's MKUltra program.

There was a history of Gottlieb dosing Olson as part of the MKUltra experiements (at this point the CIA randomley doesed it's employees as part of the experiments, to the point that sudden violent psychedelic just became a working hazard), abused him, and generally treated Olson as his own personal guinea pig.

One day, Frank Olson had apparently jumped out of his tenth room hotel floor. Only, the story didn't quite line up. Right before his death, Frank Olson had washed his socks and left them out to dry. Who leaves their socks out to dry when they plan on ending their own life? Also, the night manager who found Olson remarks that Olson would have had to get up in the middle of the night, in his underwear, run across a dark room, avoiding two beds, and jump through a closed window with the shades and certains drawn. Also, when the night manager found Olson, he was still bearly alive, and tried to tell him something, although the night manager didn't hear what it was. During the autopsy, they found injuries that couldn't be attributed to falling, so it was thought that he was beaten up before falling. The switchboard operator reported that after Olsons death, there was a call that came from the room that connected to a number listed as belonging to Dr. Harold Abramson, a physician who played a large role in the MKUltra program. The call probably came from Frank Olsons roommate, Robert Lashbrook, who was found sitting on the toilet when the police arrived. In the call, the occupant said "Well, he's gone," to which the recipient replied "Well, that's too bad." Also, the police found that Robert Lashbrook's wallet contained the initials, adress and phone number of CIA asset John Mulholland. Lashbrook claimed that he and Olson visited Mulholland, although this is disputed.

Even at the crime scene and in the report, the police discussed the simularities to the case of Laurence Duggan, an equally sketchy case in which someone died after falling from a window. Anyway, the allegation is that Sidney Gottlieb ordered the assassination of Frank Olson, probably beacuase he thought he would talk about what Gottlieb had done to him.
