Shirley Ann Stanton was found dead off the side of a road near Laughlin, Nevada, on March 16, 1989, after passengers on a bus discovered her body. Las Vegas Metropolitan Police Department homicide investigators determined she was the victim of a homicide and that her body had been there for several days before discovery.

At the time she died Stanton was relocating from Bedford, Texas, to Porterville, California. She’d reported car trouble to her mother during the trip. Her vehicle was later recovered abandoned with her dog still inside near the Vicksburg overpass on Interstate 10 in New Hope, Arizona — in La Paz County, about 100 miles east of Phoenix and close to a truck stop. Witnesses reported seeing a white semi-tractor trailer rig near her vehicle.

No suspects have been identified and the case remains unsolved. Does anyone have information about her movements along I-10 or the truck stops between New Hope and Laughlin?
