In July nineteen eighty-two, the body of sixteen-year-old Wendy Lee Coffield was found in the Green River south of Seattle. Within weeks, four more women were recovered in or near the same corridor. The discoveries began one of the largest serial murder investigations in United States history. Gary Leon Ridgway, an industrial truck painter from South King County, would later be convicted of forty-nine murders connected to the Green River case. But he was not a stranger to investigators. Years before his arrest, detectives questioned him, examined a truck lead tied to Marie Malvar’s disappearance, collected a saliva sample, and received a polygraph result that failed to reveal the truth. This episode follows the victims, the geography of Pacific Highway South and the SeaTac Strip, the creation and reduction of the Green River Task Force, the limitations of early forensic science, the preserved biological evidence that later became decisive, and the microscopic paint evidence connected to Ridgway’s workplace. It also examines the contested two thousand three plea agreement, which spared Ridgway the death penalty in exchange for guilty pleas and cooperation. Legal resolution did not answer everything. Some victims were identified only decades later through later DNA work, forensic review, genealogical research, or other investigative methods, including Lori Anne Razpotnik and Tammie Liles. Ridgway claimed more killings than his convictions prove, and the full number remains uncertain. The central question is how suspicion, evidence, science, and social neglect failed to meet sooner.
