The Great Basin Murders
On March 1, 1992 a truck driver discovered the body of Bitter Creek Betty at the bottom of a slope on an I-80 turnout known as "Bitter Creek" about 35 miles east of Rock Springs, Wyoming. She was found lying face-down, and her body may have been 1-5 months prior to discovery.
In May 2020, Clark Perry Baldwin, a truck driver from Iowa was arrested for the death of Bitter Creek Betty based on DNA evidence. On May 5, 2025 Bitter Creek Betty was publicly identified as Irene Vasquez in the Cowboy State Daily. On July 18, 2025 Clark Perry Baldwin died in custody in Tennessee where he was convicted of the 1991 first-degree murder of Pamela McCall and sentenced to life in prison. He was slated to be tried in Sweetwater County Wyoming where he was charged for the first-degree murder of Irene Vasquez.
