Francis Perry was a crooked cop working at the Boston Police rationing site, partnered up with McDonnell. He struck a deal with Sgt. John Reise to steal supplies intended for civilian distribution and sell them on the black market for a tidy profit. As he and his partner in crime were responsible for shift scheduling, this was trivial. When the heat became too great, as a result of new reports about stolen supplies, he decided to let Reise take the fall, while he bugged out to New York. Unfortunately, he was overheard recording a message for his cousin and the two criminals promptly killed each other - right on the eve of the Great War.
Francis Perry is mentioned only in Fallout 4.
