A former trucker from Waterloo has been arrested and charged with the murder of three women, in two different states, in the early 1990s.

58-year-old Clark P. Baldwin of Waterloo has been charged with the March 1991 murder of 32-year-old Pamela McCall of Virginia. McCall, and her 24-week-old fetus, were killed in Tenessee.

According to a press release from the Tennessee 22nd Judicial District Attorney's Office, McCall's body was found near the woods, about 100 feet from a Tennessee roadway on March 10, 1991. An autopsy revealed that she died from strangulation. WHO-TV reports sperm was also found on pantyhose that McCall was wearing.

Baldwin has been charged with two counts of first-degree murder in Tenessee in the case. He will be extradited to Tennessee.

In Wyoming, Baldwin has been charged with first-degree murder in the deaths of "Bitter Creek Betty" and "I-90 Jane Doe."

"Bitter Creek Betty" was not identified. She was found in Sweetwater County, Wyoming in April of 1992.

The following month, DOT employees in Wyoming found the body of a woman in Sheridan County. She was also not identified and became known as "I-90 Jane Doe."

The two women have still not been identified.

According to a press release from the Office of the Attorney General in Wyoming, "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."

Investigators were also able to retrieve DNA in each of the Wyoming murders. WHO reports the FBI recently collected DNA from Baldwin's trash and off of a shopping cart he used at a Walmart store in Waterloo. Baldwin's DNA matched a profile developed in the Tennessee Crime Laboratory in 1991. It was also a match for the profile that had been developed in the two Wyoming cases.

Wednesday morning, two Tennessee District Attorney Criminal Investigators, Iowa Division of Criminal Investigation agents, agents from the Division of Criminal Investigation in Wyoming, and the Federal Bureau of Investigation, arrested Baldwin at his Waterloo home. He is expected to face the charges from the Wyoming murders after the Tennessee charges.

Before living in Waterloo, Baldwin was a resident of Nashua, Iowa and Springfield, Missouri. In the early 1990s, he was a driver for Marten Transport.

Could the arrest of Clark Baldwin lead to more cases being solved? Matt Waldock, Wyoming Division of Criminal Investigation Commander, told WHO he was "hopeful."
