As the number of victims connected to the Green River increased, authorities established a dedicated task force to investigate the murders. The scale of the investigation rapidly expanded, involving multiple agencies and extensive resources. This marked the transition from isolated cases to one of the largest serial murder investigations in U.S. history.
The Green River and surrounding wooded areas served as primary disposal sites for victims.
The task force coordinated efforts across jurisdictions, collected forensic evidence, and developed early offender profiles. Thousands of leads were pursued, but no suspect was definitively identified at this stage.
