Donna Lee Ingersoll, 25, was last seen the night of December 16, 1990, in Wabasha, Minnesota. She had been at a gathering with five others when she got into a heated argument with her boyfriend, Gary Murphy, and witnesses say she ran out the back door around 11:45 p.m., leaving her purse, vehicle, and glasses behind. It was a cold winter night and she did not appear to have taken a coat.

An extensive search turned up no trace of her. Authorities have long suspected foul play because of the circumstances of her sudden departure and the lack of evidence that she left voluntarily. Murphy was reportedly emotionally distressed after Donna’s disappearance, checked into a treatment center, and died by suicide the following year, but no definitive connection between his death and Donna’s disappearance has been established.

Donna lived in Hammond, Minnesota, and graduated from Rochester John Marshall High School. Her case remains unsolved; anyone who knew Donna, was in Wabasha on December 16, 1990, or has relevant information is asked to come forward.
