“Teacup Poisoner” Graham Young began his creepy career when he was still a child, slipping poison to members of his family. Before he was finally caught and sentenced to Broadmoor in 1962, he’d poisoned more than a dozen people and killed at least three. Family, coworkers, friends. And he didn’t stop even after he was incarcerated. A couple of his fellow inmates at Broadmoor fell victim to his deadly chemistry, too. Then there’s Dr. Michael Swango, one of the most prolific serial killers in American history. He started young, too. When he was just a kid, he created a scrapbook full of gory newspaper clippings about accidents and murders. And once he started poisoning, he didn’t stop until hundreds of victims lay in his wake. Poisoners fall in love with poison. With watching from a distance as their victims sicken and die. The power is intoxicating. The fact that they can stay hidden in the shadows with the power of life and death in their hands. We’re about to tell you two stories about two very different poisoners.
