The Illinois State Police on Friday made an announcement about the May 6 arrest in Iowa of Clark Terry Baldwin. He was wanted for the 1991 Tennessee murders of Pamela McCall and her unborn son, and the murders of two unidentified women discovered separately in Wyoming in 1992.
In the ISP announcement, titled "Illinois State Police Announce An Update to the Tammy Zywicki Case," the ISP indicated that "at this time, Baldwin does not appear to have been involved with the murder of Tammy Zywicki."
Zywicki, a 21-year-old college student, was abducted and killed by an unknown assailant after experiencing car trouble on I-80 near LaSalle, IL in August 1992. Reports at the time that she had been picked up by a trucker led nowhere.
Baldwin was a long-haul trucker and suspected serial killer operating during the same time frame. He fit the profile of Zywicki's murderer and it was reported that authorities were investigating whether he might be involved.
The ISP said it was continuing to investigate Zywicki's murder and "remained committed to pursuing justice" for her. It asked anyone who might have some information that might assist the continuing investigation to please contact the ISP, Division of Criminal Investigation, Zone 3, at 815-726-6377.
