DES MOINES, Iowa (AP) — Few details are being released about a federal investigation into allegations that sexual arousal experiments were done on residents of a state-run Iowa institution for developmentally disabled residents. The U.S. Department of Justice notified Gov. Kim Reynolds in November that investigators will see if there are law violations at Glenwood Resource Center, an investigation first reported by the Des Moines Register. The investigation is focusing on whether residents were subjected to harmful and uncontrolled human experiments and whether they had inadequate medical and nursing care. Investigators also will look at whether there have been harmful restraint practices and needless injuries.

IOWA CITY, Iowa (AP) — The state auditor on Monday criticized $40,000 in relocation benefits that helped a veteran Iowa State Patrol supervisor relocate his family home farther away from his new assignment in western Iowa. State Auditor Rob Sand concluded that there was no “public benefit” for taxpayers to cover closing costs and other expenses on the sale of Lt. Joel Ehler’s home in Adel. Sand’s office investigated the matter after The Associated Press reported on the benefits in May. An internal investigation by the Iowa Department of Public Safety found that the benefits were appropriate and that Ehler did nothing wrong.

DES MOINES, Iowa (AP) — Vandals have defaced the artwork and property of an Iowa man who displayed paintings of Confederate flags and swastikas in his front yard. The Des Moines Register says the vandal or vandals scrawled the words “Nazi scum” on a trailer and the pickup parked at William Stark’s house in Des Moines and spray-painted over several of the wooden pallets in his yard on which he had painted the Confederate battle flag. The vandalism was discovered Wednesday. Stark told the newspaper for a story earlier last week that he isn’t a racist or white supremacist and would paint any flag, if asked.
