Des Moines Register: A top health official for the state of Iowa knew of plans for a “sexual preoccupation” study at a state-run institution for people with severe disabilities well before federal officials began investigating the facility late last year, according to newly released emails. Rick Shults, the mental health and disability services administrator for the Iowa Department of Human Services, approved a software request on May 21, 2018, for studies on patients at the Glenwood Resource Center and on patients who are part of a state-run program for sexual offenders, according to emails DHS provided to the Des Moines Register as part of a records request.
