In an interview with the LaSalle, Ill. News Tribune, Mrs. Zywicki said that the FBI has been in touch with the police in Nashville, Tenn. where suspected serial killer Bruce Mendenhall was arrested. Mendenhall has already confessed to six murders:
"We live with it every day and we’d certainly like to have closure with it," said Zywicki, adding she checks Internet sites, blogs and other media frequently in search of information. She said she keeps track of interstate and truck stop murder cases, and she also continues to study about murderers.
Several times she has had some reason to suspect accused killers in other cases may have had a hand in her daughter’s death, but often they have had alibis or could not have been driving a truck at the time of the killing or they had log books that did not indicate they were in the Illinois Valley at the time of the Aug. 23, 1992, Zywicki kidnapping.
Tammy Zywicki's body was found in Lawrence County about halfway between Joplin and Springfield in 1992.
