Baldwin is being charged in Wyoming with First Degree Murder of both “I-90 Jane Doe” (Sheridan County) and “Bitter Creek Betty” (Sweetwater County). Additionally, Baldwin is being charged in Tennessee with two counts of First Degree murder in the 1991 death of Pamela McCall and her unborn fetus.

This case began in March of 1992, when a female was found deceased near the Bitter Creek turnout in Sweetwater County Wyoming. The investigation was initiated and investigated by the Sweetwater County Sheriff’s office but after time grew “cold”. During the course of the investigation, the victim was not identified and became known to the investigators as “Bitter Creek Betty”.

In April of 1992, another deceased female body was discovered in Sheridan County by the State of Wyoming DOT employees. The investigation was initiated and investigated by the Sheridan County Sheriff’s office but again the case grew “cold”. During the course of the investigation, the victim was not identified and became known to the investigators as “I-90 Jane Doe”.

Investigators did all they could and exhausted all the technology available to them at that time. I-90 Jane Doe and Bitter Creek Betty remain unidentified.

The Wyoming Division of Criminal Investigation joined the investigation of “Bitter Creek Betty” and “I-90 Jane Doe” and worked hand in hand with local Investigators and prosecutors.

Despite the passage of time, Agents, Investigators and Prosecutors never forgot about the untimely deaths of the victims. Due to advances in technology, they were able to link Baldwin to the crime and arrest him on first-degree murder charges from Sheridan and Sweetwater counties.

Involved Agencies constantly looked for ways to use current technologies and new approaches as well as being able to combine best science with the most viable evidence. With the assistance of the Wyoming State Crime Laboratory and the FBI, these methods provided answers to our investigators that helped further the investigation to a successful resolution.

This is a great example of the quality work Agents and Investigators of these agencies do on a day-to-day.
