Stephen Malmgren faces four counts of aggravated criminal sexual assault for an incident that happened at Lutheran Hillside Village on North Galena Road. Employees told police they stumbled upon Malmgren assaulting the victim while they were looking for him to treat another patient. According to court records, Malmgren was working an overnight shift when two employees say they went looking for him to treat a different patient and stumbled upon him in the resident’s room, witnessing the assault. Those employees reported it to the nursing home administrator. The Illinois Department of Public Health is also looking into the nursing home and its handling of the situation.
