On April 13th, 1992, a decomposed body was recovered from a ditch parallel to Interstate 90, only five miles from the border between Wyoming and Montana. The victim—still unidentified and referred to as Sheridan County Jane Doe—was white, between sixteen and twenty-one years old, standing about five-foot-five and weighing one-hundred-ten pounds. She had shoulder-length brown hair that was bleached by the sun, and was clad in a blue-and-white checkered midriff shirt, jeans, and a white plastic belt with a silver buckle. No shoes or socks were found.
It appeared that the victim had been killed by blunt force trauma to the head and face, though it is not known whether she was sexually assaulted. Authorities determined she had been murdered elsewhere, likely about two months before, and then dumped from a vehicle into the ditch where she was later discovered.
Later DNA tests would show that her killer and that of Bitter Creek Betty were the same man, and in 2020, this individual was identified as fifty-nine-year-old Clark Perry Baldwin, originally from Waterloo, Iowa. He was arrested in May of that year and charged with the murders of three women: Sheridan County Jane Doe, Bitter Creek Betty, and Pamela McCall, who was murdered in Tennessee in March of 1991. Since Pamela was pregnant at the time of the murder, Baldwin was also charged with killing her unborn child.
