Rose Peterson was 41 when she walked away from the West Side Adult Foster Care Home in Calumet, Michigan, on Friday, July 28, 1989. She left an employee’s home about noon and was considered an endangered adult at the time, with concerns she may have been suicidal. A confirmed sighting the next day put her walking south along US-41 near Houghton County Memorial Airport; she told well-wishers she was heading to Hancock and declined a ride. That was the last confirmed contact.

At disappearance she wore a blue sweatshirt or jacket, a white blouse, blue or black sweatpants, blue canvas shoes, carried a purse, and wore prescription eyeglasses. She had short curly brown hair and hazel eyes and was a mother with a 14-year-old son. Michigan State Police searched the foster home area, the US-41 corridor, and friends’ homes in Hancock; a Calumet Post detective later continued the investigation but no trace has ever been found. The family has kept the case in public view, including participation in a 2017 podcast. Does anyone who lived in the Calumet–Hancock area in July 1989 remember seeing Rose or have information that could help explain what happened?
