[ Editor's note: This article mentions sexual assault.] It wasn’t long after a gray RV appeared in her North Portland neighborhood’s cul-de-sac that Erica knew something was off. It was the vehicle’s appearance that first raised suspicion: The RV was missing its license plates and, in place of traditional door locks and handles, the owners had installed screws to keep the doors secure. Then Erica began waking up to late-night activity at the vehicle— people in luxury cars were parking on the street, entering the RV for no more than 15 minutes, and then driving off. During each visit, individuals carrying guns would appear to stand guard outside the RV.
