WATERLOO MAN, CHARGED IN TENNESSEE AND WYOMING COLD CASE HOMICIDES, IS SUSPECTED SERIAL KILLER

 
Just one day after after the Iowa Division of Criminal Investigation (DCI) announced the arrest of a suspect in the June 2004 death of Bonnie Callahan, 73, of Keokuk, Iowa, the DCI announced that a Waterloo man was being charged with the 1981 murder of Pamela McCall in Tennessee and two 1992 homicides in Wyoming.

On May 6, 2020, the DCI assisted the Federal Bureau of Investigation, the Wyoming Department of Criminal Investigation and the Tennessee 22nd Judicial District Attorney’s Office with the arrest of Clark Perry Baldwin (DOB 8-22-61) of 209 W. 5th Street #612, Waterloo, Iowa.

Baldwin, 58, is charged with two counts of murder in the 1991 Tennessee killing of 32-year-old Pamela Rose McCall and her unborn fetus.

He’s also charged in the deaths of two women whose bodies were found in 1992 roughly 400 miles apart in Wyoming. The women, who were never identified, are referred to as “Bitter Creek Betty” and “I-90 Jane Doe.”

Federal authorities used forensic genealogy — the practice of using genetic information in online databases — and looked at similar cases, which eventually led them to Baldwin, said Brent Cooper, attorney general of the 22nd Judicial District in Tennessee.

Baldwin was taken into custody Wednesday, May 6, at his Waterloo home after investigators linked his DNA with semen and other materials recovered from the victims.

Baldwin worked as an over-the-road truck driver for most of his career, living in Nashua and Waterloo, Iowa, and Springfield, Missouri.

Though the suspected serial killer is being questioned in multiple unsolved murders across several states, authorities in Illinois say Baldwin “does not appear to have been involved” in the unsolved 1992 slaying of Iowa college student Tammy Zywicki.

This is an ongoing, multi-state and federal investigation, and updates will be posted on the Iowa Cold Cases “News” page as more details come to light.
