A few years ago when the “Manhunt: Unabomber” mini-series was released on Netflix we are told from the beginning the FBI was well aware that Freedom club, or FC, was not a group but an individual.

My question is, how did they know this? Especially seeing how few leads there were for so long why would they discount this clue? I would love to learn of the process they took to eliminate the idea of the Unabomber being a group.

When I attempted to research this myself I found no results on this particular question.
