1992 Kidnapping And Murder Of College Student Remains Focus Of FBI/ISP Probe

Press Release Date: August 21, 2012    || Archived February 11, 2013

CHICAGO - Robert D. Grant, Special Agent-in-Charge of the Chicago office of the Federal Bureau of Investigation (FBI) was joined today by Hiram Grau, Director of the Illinois State Police (ISP), in asking for the public’s help in identifying the person or persons responsible for the August 23, 1992 kidnapping and murder of  Tammy Zywicki.

 A 21-year old college student from Marlton, New Jersey, Ms. Zywicki was en route to Grinnell College in Iowa when her vehicle became disabled on Interstate 80 at mile marker 83 near Utica, Illinois. She was last seen standing on the side of the road with a truck driver, who had apparently stopped to render assistance. Her body was found nine days later along Interstate 44 near Lawrence, Missouri. She had been sexually assaulted and stabbed to death.

A multi-agency task force, headed by the FBI and ISP, was formed to investigate this crime immediately after Ms. ZYWICKI’s disappearance. During the ensuing months, hundreds of leads were pursued in an effort to identify her killer, without success. Although the full task force has been disbanded, this case is still under active investigation by both the FBI and Illinois State Police in an attempt to solve this crime.       

“On the occasion of the 20th anniversary of Tammy’s disappearance, we are again calling on anyone with knowledge of this crime to come forward and provide to law enforcement, the information needed to bring this investigation to a close” said Mr. Grant. “We remain confident that someone knows who committed this heinous act and will have the courage to help us identify this individual.”

Director Grau echoed his Agency’s commitment to solving this case. “This investigation remains a top priority, both for me personally as well as the men and women of the Illinois State Police.”  Director Grau added, “We have strengthened our investigative resources, in partnership with the FBI, and are committed to bringing justice and peace to the Zywicki family.”

A reward of up to $50,000 is being offered for information leading to the identification of the individual(s) responsible for the kidnapping and murder of Ms. Zywicki. Anyone having information about this case is asked to call the Chicago FBI at (312) 421-6700.
