Tonya K. Teske, 18, was found dead and naked on a grassy slope off U.S. Highway 20 near Ucon, Idaho, on August 15, 1997. A truck driver and his wife discovered the body; identification took ten days because no one had reported her missing. Teske was originally from Shoshoni, Wyoming, had dropped out of high school in 1995, and had been hitchhiking through Utah, Wyoming, Idaho and Montana, estranged from her family with her last contact in January 1997.

The last confirmed sighting was August 13, 1997, at the Cinnamon Lodge truck stop in Gallatin County, Montana, where she carried a large green suitcase and a brown shoulder bag and was questioned about allegedly soliciting sex over CB radio. Investigators found evidence of sexual assault; toxicology was inconclusive and there were no obvious external wounds, but authorities treated the death as a potential homicide. Since October 1997 an unidentified Idaho truck driver has been named a person of interest after evidence in Island Park linked him to Teske; no arrests have been made.

Does anyone who saw Tonya in mid-August 1997 or who has information about truck traffic between Montana and eastern Idaho know anything that could help?
