Susan Poupart was a 29-year-old Native American mother of two who disappeared in the early morning hours of May 20, 1990, after attending a party on the Makwa Trail in Lac Du Flambeau, Wisconsin. Around 4:00 a.m. she was last seen leaving the gathering with two men; some witnesses said she got into a car willingly, while at least one witness said she appeared to be forced into the vehicle. Her family reported her missing when she did not return home.

On Thanksgiving Day, November 22, 1990, two hunters discovered a purse with Susan’s tribal ID and a jacket in the Chequamegon-Nicolet National Forest. Partial human remains beneath those items were later identified as Susan’s. Investigators found duct tape and plastic at the scene; the remains showed evidence of sexual assault, and the death was officially ruled a homicide though a precise cause of death could not be determined.

Investigative attention centered on two men last seen with Susan, Joe Cobb and Robert Elm, who said they dropped her off near an elementary school after an argument. A third man, Francis Fritz Schuman, was later named as a person of interest amid claims he confessed to another inmate about involvement. Charges brought in 2007 were dismissed when witnesses declined to testify. The case remains unsolved and cold.

Did anyone who knew Susan or who was in Lac Du Flambeau that May have information that could help resolve what happened?
