In this epic, seven-part feature, Scott Farwell tells the story of Carol Blevins, a heroin addict and “Aryan Princess featherwood” (property of a gang member) who became the FBI’s most important confidential informant in a massive, six-year investigation into the Aryan Brotherhood of Texas — an organized crime syndicate responsible for over 100 murders and a huge drug trade. Blevins’ keen eye for detail helped take down 13 members of the gang, and they’ve signalled the “green light” on her assassination in a bid for revenge.
