The Internet Killer: John Robinson and the Birth of Online Predation
John Edward Robinson appeared to be the last person anyone would suspect of becoming a serial killer. He was a suburban husband and father living in the Kansas City area, a man who wore collared shirts, attended community functions, and projected calm professionalism. Beneath that carefully constructed fa ade, however, Robinson spent decades refining a hidden life built on fraud, manipulation, psychological control, and eventually murder. Long before society understood the dangers of online predation, Robinson recognized the internet as a perfect hunting ground.
During the 1970s and 1980s, Robinson established himself as a skilled conman, drifting through fraudulent businesses, forged documents, fake charities, and financial scams. He repeatedly targeted vulnerable individuals searching for stability or opportunity, especially women facing emotional or financial hardship. One of his earliest known victims, Lisa Stasi, disappeared in 1985 after meeting Robinson through a women's shelter in Kansas City. Her infant daughter was illegally transferred through forged adoption paperwork arranged by Robinson, revealing the disturbing blend of manipulation and administrative deception that would define many of his crimes.
As the internet expanded during the 1990s, Robinson evolved alongside it. Entering online BDSM chatrooms under aliases such as "Slavemaster," he built false digital identities designed to attract vulnerable women. He presented himself as wealthy, dominant, experienced, and emotionally protective, carefully tailoring his persona depending on each victim's emotional needs. Robinson understood something most of society did not yet recognize: people formed intense emotional attachments online far faster than they did face-to-face. He used endless late-night conversations, promises of employment, financial stability, relocation, romance, and control to create psychological dependency before victims ever met him physically.
Women who entered Robinson's orbit often believed they were beginning new lives. Instead, many disappeared.
The investigation became historically significant because it combined traditional homicide investigation with some of the earliest major uses of digital forensic evidence in a serial murder case. Detectives reconstructed Robinson's online communications, revealing how he used chatrooms and anonymous identities to manipulate vulnerable women long before law enforcement fully understood cyber-enabled predation. Prosecutors demonstrated that Robinson had integrated the internet directly into the architecture of his crimes, using technology to identify victims, build trust, encourage secrecy, and facilitate isolation.
National media soon labeled Robinson "The Internet's First Serial Killer," a phrase that captured public fear during the early years of widespread internet adoption. His crimes shattered the popular belief that online spaces were largely harmless and exposed how easily anonymity, emotional vulnerability, and digital communication could be weaponized by predators.
Ultimately convicted in Kansas and Missouri, Robinson received multiple life sentences and a death sentence. Yet his legacy extended far beyond the courtroom. Criminologists, cybercrime experts, and investigators continue studying the Robinson case because it marked a turning point in understanding modern online predation. Many techniques now associated with romance scams, catfishing, online grooming, coercive control, and cyber-enabled exploitation were visible in Robinson's methods decades earlier.
John Robinson was not merely a serial killer who used the internet. He was one of the first predators to recognize what the digital age would eventually make possible.
