The top officials at a state-run institution for people with severe disabilities directed the purchase of sexual lubricants, silk sheets or boxers and pornographic images in preparation to study patients’ sexual arousal, according to a new lawsuit filed by former employees at the facility. The lawsuit, filed Monday by six former employees at the Glenwood Resource Center, claims former Glenwood Superintendent Jerry Rea and other managers purchased a dedicated computer, software program and joystick for the sole purpose of sexual arousal research at the facility. The former employees, who include former Glenwood center doctors and top administrators, further claim in a 37-page lawsuit filed in the U.S. District Court for the Southern District of Iowa that the medically fragile patients’ medications were changed to prepare for the study. “They intended to use, and did use, highly vulnerable GRC patients as the ‘guinea pigs’ in research experiments,” the suit says. The lawsuit was filed in the midst of an ongoing federal investigation into the Glenwood Resource Center.
