Cecelia Genatiempo was a 17-year-old female from Gloversville, New York, and the last time she was known to be alive was on the night of July 24 into July 25, 1976, when she was taken from a donut shop in town. Investigators later determined she had been driven away to a remote stretch of railroad tracks near Mohawk, where she was sexually assaulted and stabbed repeatedly, then hidden in a shallow grave.
Her body was not discovered until roughly three months later, when hunters came across her remains in the area.
For years, the killing sat in the background of other violence that was unfolding across the Mohawk Valley. The break came in August 1979, after a separate abduction and stabbing investigation led New York State Police to a suspect whose appearance and vehicle matched the survivor’s description. Troopers went to John William Hopkins’ home on August 15, 1979, and he agreed to accompany them to the barracks, where he denied involvement at first, signed consent forms for searches, and agreed to a polygraph. After the surviving victim identified him, he was arrested in the early hours of August 16.
Later that morning, Hopkins began confessing. According to the appellate record, he admitted involvement in Genatiempo’s murder, helped prepare a written statement describing what he had done, and drew diagrams of the abduction scene and the knife he used. That same day, he was arraigned in the afternoon, and that night he again spoke about the killings—this time to a correction officer while being monitored in jail—saying he was glad he had been caught and implying he might have gone on to commit more crimes if he hadn’t been stopped.
Hopkins was prosecuted for Genatiempo’s case and convicted; the appellate decision notes the jury verdict included multiple serious charges connected to her kidnapping, sexual assault, and death, and his conviction and the trial court’s rulings allowing his confession were upheld on appeal. The courts rejected arguments that his statements should have been suppressed, finding the record supported that he had gone with police voluntarily before his formal arrest and that his later statements were admissible under the circumstances described.
In the broader sequence of events, Hopkins’ confessions also implicated him in another Mohawk Valley murder, and he ultimately received lengthy prison terms; accounts of the prosecutions describe separate trials and life sentences, with Hopkins remaining incarcerated until his death in prison years later.
