The Slavemaster: John Edward Robinson and the Birth of the Internet Serial Killer

In the summer of 2000, investigators searching a rural Kansas farm made a discovery that would rewrite the history of American serial crime: five women, stored in chemical drums, killed across nearly two decades by a man his victims knew only as the Slavemaster. John Edward Robinson was a grandfather, a suburban businessman, and the first documented internet serial killer in American history, a man who had spent a lifetime forging credentials, fabricating identities, and exploiting the institutional trust of every system he entered, before finding, in the anonymous architecture of early online chatrooms, the perfect infrastructure for his most lethal phase of predation.

The Slavemaster traces Robinson's full biographical arc from a volatile childhood in postwar Cicero, Illinois, through decades of sophisticated white-collar crime, to the shell companies that became recruitment vehicles for murder and the BDSM online communities he infiltrated with predatory precision. Drawing on court records, forensic findings, and the ninety-one thousand digital files recovered from his computers, this book reconstructs not only the crimes but the system behind them, examining the forensic breakthroughs, the families who refused to stop asking questions, and the investigative legacy that transformed how law enforcement pursues predators in the digital age.
