Authorities in Illinois say an Iowa man charged in 1990s serial killings “does not appear to have been involved" in the unsolved 1992 slaying of a college student.
The Illinois State Police said Friday that Clark Perry Baldwin is not a suspect in the death of 21-year-old Tammy Zywicki.
The statement appeared to rule out what had seemed to be a promising lead in the case of Zywicki, who was abducted after experiencing car troubles on Interstate 80 near La Salle, Illinois, in 1992. She was returning from Evanston to Grinnell College in Iowa. Her body was found in Missouri days later, with evidence of stabbing and sexual assault.
Police arrested Baldwin, a former truck driver, at his home in Waterloo, Iowa, on Wednesday. He's charged in the deaths of two women who were found in Wyoming in 1992 and a woman whose body was found the prior year in Tennessee.
A retired investigator who worked on Zywicki's case had told the La Salle News Tribune that the allegations against Baldwin in other cases fit the profile of the person who killed Zywicki.
The Illinois State Police didn't elaborate on why Baldwin isn't suspected but said the case remains under investigation.
