In June of 1996, a 49-year-old woman named Catherine Dext was admitted to the Hunterdon Medical Center in Raritan Township, New Jersey, for a ruptured spleen. Her condition, while serious, was not considered terminal. However, her life was cut short in a manner that would only be understood years later as the work of a serial killer. Dext, a supervisor at the Edna Mahan Correctional Facility for Women, was described by a colleague as a low-key person who consistently fulfilled her duties.
During her hospital stay, Catherine Dext became a victim of Charles Cullen, a nurse who moved from one medical facility to another, leaving a trail of suspicious patient deaths in his wake. Cullen administered a lethal injection of the heart medication digoxin to Dext, causing her death on June 9, 1996. Her passing was not immediately recognized as a homicide, allowing Cullen to continue his killing spree for several more years across various hospitals in New Jersey and Pennsylvania.
Years later, following an extensive investigation into a pattern of patient deaths at different hospitals where he had been employed, Charles Cullen was arrested. He eventually pleaded guilty to the murders of 29 people, including Catherine Dext, and the attempted murders of six others. Cullen confessed to investigators that he may have been responsible for as many as 40 deaths, though that number could not be officially confirmed. In exchange for his cooperation in identifying his victims, he was spared the death penalty and sentenced to multiple life terms in prison.
