On March 10, 1991, the body of 33-year-old Pamela Rose Aldridge McCall, a white female, was found near Saturn Parkway in Spring Hill, Tennessee. McCall, who was 24 weeks pregnant, had been strangled to death and her unborn child also perished. Her clothing was torn and she had visible injuries to her face and neck. She was described as free-spirited and transient and was believed to have been hitchhiking and traveling with a semi-truck driver around the time of her death.

The investigation lay cold for decades until evidence from the original scene was submitted for modern DNA analysis. A full DNA profile of an unknown white male matched DNA from two unsolved 1992 homicides in Wyoming, which led investigators to Clark Perry Baldwin, a former truck driver from Waterloo, Iowa. He was arrested on May 6, 2020, and charged with two counts of first-degree murder for McCall and her unborn child. In May 2025 a Maury County jury found Clark Baldwin guilty and he was sentenced to life in prison; he was to be extradited to Wyoming for the earlier cases.

If anyone knew Pamela, traveled the Saturn Parkway area in March 1991, or remembers a trucker and passenger matching this description, what information can be shared with investigators?
