The Illinois State Police are putting out a renewed call for tips in the 28 year old murder of college student Tammy Zywicki. Tammy Zawycki was a 21 year old college student from Evanston, Illinois who was traveling alone to Grinnell College in Grinnell, Iowa when, on August 23rd, 1992, she went missing. That day, Zywicki’s 1985 Pontiac T1000 was found on the side of Interstate 80 near Utica, Illinois in LaSalle County. No sign of Zywicki was found in the vehicle. More than a week later, Zywicki’s body was found nearly 7 hours away in near Highway 44 in Lawrence County Missouri. On August 23rd, witnesses indicated seeing a semi and trailer on the side of the road near where Zywicki’s car was found. It is theorized that she may have accepted a ride from a truck driver the day she died. No other witnesses have come forward with more detailed accounts since.
The Illinois State Police, in coordination with the FBI and the LaSalle County State’s Attorney’s office, remain committed to pursuing justice for Tammy and her family. This anniversary marks 28 years that Zywicki’s family and friends have endured the loss of her love and friendship. Our thoughts remain with her family and friends. We ask if anyone has any information on the kidnapping and murder of Tammy Zywicki to please contact the Illinois State Police at (815) 726-6377 or the Chicago FBI Field Division at (312) 421-6700. Her case remains an active and ongoing criminal investigation.
