The Slavemaster Killer: The Businessman Who Hunted Women Online

John Robinson was the last person anyone expected to become one of America's most disturbing killers. A churchgoing father, Scoutmaster, and respected Kansas City businessman, he hid a second life built on manipulation, fraud, and murder. Under his online persona, the Slavemaster, Robinson lured vulnerable women with promises of work, housing, and love, only for them to disappear without a trace. When investigators finally closed in on him in 2000, they uncovered a nightmare across two states. Barrels filled with bodies. Forged letters to families. Stolen identities. And one devastating truth: baby Heather Robinson, raised by Robinson's brother, was actually the daughter of one of his victims, Lisa Stasi. Robinson's crimes earned him the title of America's first internet serial killer. Now on death row, he has never fully revealed how many women he targeted or how far his violence went. Was he a con man who escalated into murder, or was he always a predator waiting for the internet to give him cover? Learn more about your ad choices. Visit megaphone.fm/adchoices
