By blending emotional narrative with clear facts, readers gain insight into why this case continues to resonate today.
John Robinson’s Early Life and Warning Signs
John Edward Robinson was born December 27, 1943, in Cicero, Illinois, to Henry and Alberta Robinson. He briefly attended seminary school and Morton Junior College but dropped out twice before marrying Nancy Jo Lynch in 1964.
Neighbors recall a polite young man raising four children—John Jr., Kimberly, and twins Christopher and Christine—but behind the facade, financial crimes were simmering. By the late 1960s, Robinson faced charges of embezzlement. These early run-ins with the law hinted at a man capable of deception long before any violent crime emerged.
Shocking Murders and Internet Lure
Between 1985 and 2000, Robinson murdered at least eight women across Kansas and Missouri. He used the alias “Slavemaster” in online chat rooms to lure victims under false promises of work or help.
In January 1985, he killed 19-year-old Lisa Stasi and placed her infant daughter, Heather, with his brother and sister-in-law, signing forged adoption papers and billing thousands in fake fees. Investigators uncovered decomposed remains stored in barrels on his 16-acre property and a rented storage unit, confirming the breadth of his atrocities.
Impact on Heather Robinson
“I knew him as Uncle John,” Heather once recalled. At age fifteen, she discovered that her birth mother was among Robinson’s victims. The revelation sparked trauma and a quest for answers.
With support from her grandmother, Patricia Sylvester, Heather launched The Lisa Stasi Effect podcast to honor her mother’s memory and raise awareness about victims’ rights. “My name carries both pain and strength,” she said, choosing to keep “Heather Robinson” to bridge her adoptive and biological families.

Trials, Sentencing, and Appeals
Robinson’s Kansas trial in 2002 became the state’s longest, ending with convictions for three capital murders and two death sentences, plus life for a third victim. In Missouri, he pled guilty to five more murders in 2003, receiving five life terms without parole.
He remains the first known serial killer to use the Internet as a hunting ground. Despite appeals—some convictions dropped on technical grounds in 2015—the Kansas Supreme Court upheld his death sentence, and his 2022 bid for a new trial on counsel-ineffective grounds continues to languish.
Current Status and Legacy
Now 81, John Robinson sits on death row at El Dorado Correctional Facility in Kansas, with no release date in sight. His case reshaped online safety protocols and inspired the Lifetime film Kidnapped by a Killer: The Heather Robinson Story, premiering June 7, 2025.
Steve Guttenberg portrays the killer, bringing renewed focus to victims and survivors. Robinson’s chilling ability to blend into suburban life underscores ongoing concerns about trust, technology, and the hidden darkness that can lurk behind familiar faces.
Final Words
The story of John Robinson serves as a stark reminder that evil can masquerade as a friendly face. Through Heather Robinson’s courage, we see how survivors reclaim their narrative and spark change. As true-crime dramas captivate audiences, Heather’s advocacy ensures that victims’ voices echo louder than any barrels once hidden from view.
