Green River, in Washington State, USA, flows south-eastward from Seattle-Tacoma International airport toward Mt. Rainier National Park. Its trajectory snakes the interstitial annals of human industry into edenic nature, an evergreen idyll. 15 years ago, Gary Ridgway, the most prolific serial killer in American history, was sentenced to life imprisonment without parole for the brutal murders of up to 90 women, many of whom were involved in sex work, a profession that Ridgway both abhorred and fetishized. Ridgway strangled his victims then dumped their bodies in forested areas, mostly around Green River, which earned him the moniker ‘the Green River Killer’. He often returned to this landscape to have sexual intercourse with the decaying bodies of his victims.
