REMEMBERING: Donna Ingersoll (10 of Clubs, Minnesota)

On a snowy December night 35 years ago, 25-year-old Donna Ingersoll stormed outside and disappeared into the darkness after a heated argument with her boyfriend, leaving behind several important belongings and a twisted web of mysteries investigators have spent decades trying to untangle. Since 1990, Donna’s disappearance has weighed on the small town of Wabasha, Minnesota, as the passage of time has produced more questions than answers. But some recent developments have present-day investigators questioning everything they thought they knew about the case — and believing they’re closer than ever to cracking it. At the time she went missing, Donna was 4’11” and 106 pounds, had blonde hair and green or hazel eyes, and was last seen wearing boots and blue jeans. She would be 60 years old today.
