There are credible journalist that after sifting through the evidence believe this is the case. It seems to bizarre and conspiracy theory like to be true, but I wouldn't be surprised. Been doing some reading about the MKUltra program and it's absolutely horrifying. A member of my family who I love very much committed a locally famous murder when he was a boy, well before I was born. If he did it today it might end up on Nancy Grace. I wasn't told about it until I was in my early teens, it hit me like a pile of bricks. He was also diagnosed as schizophrenic. When I was too young to know about what happened, I had on at least one occasion someone say some really fucked up things to me regarding the murder. I was a child and it made no sense at the time. Knowing what I know now it was some pretty awful shit to say to a child. Life did go on for my family and overtime for the family member who committed the murder, it's hard for the family, and hard on the individual, but life goes on.
Also, fuck Nancy Grace and her citizen brigade, I hope your uncle is fairing well.
