DES MOINES, Iowa (AP) — The director of the Iowa Department of Human Services has sought help from state criminal investigators to look into allegations at the Glenwood Resource Center.

The agency learned last month that federal officials were investigating whether the state is violating the federal rights of Glenwood residents by placing them at risk with uncontrolled human subject experiments. Federal officials also are seeking to learn if there have been practices causing needless injury.

Iowa Division of Criminal Investigation Assistant Director Mitch Mortvedt says Tuesday his agency was called in to help and is evaluating information in the ongoing investigation..

Glenwood is home to people with developmental disabilities.
