On January 12th, 1983, the police department in Brattleboro, Vermont, got a strange call from some colleagues at a local company about a case of what they thought to be false identity. The woman in question worked as a secretary at the company and called herself Teri Martin. Martin claimed to be the twin sister of a woman named Robbie Hannon, who had recently died and who had been married to her brother-in-law, John Greenleaf Hannon III. Except there was no Teri Martin. And there was no Robbie Hannon. There was only Marie Hilley.
Audrey Marie Hilley, who preferred to go by Marie, was born and raised in Anniston, Alabama. That is where she grew up, got married the first time and raised her two children. She also had multiple affairs with her bosses, tried to poison both of her children with arsenic, and succeeded in doing so with her first husband. Marie Hilley would go on to wreak havoc all over the South and the NorthEast, leaving a trail of false identities and dead bodies in her wake.
