Tammy J. Zywicki
Justice for Tammy J. Zywicki โ the trail went cold in 1992, but the truth hasn't.
Start here
Who was the tractor-trailer driver (white male, 35-40 years old, over 6 feet tall, dark bushy hair) seen near Zywicki's vehicle at mile marker 83 on I-80?
What happened to the missing Cannon 35mm camera and Lorus musical wristwatch (green umbrella face, plays 'Raindrops Keep Falling On My Head') that Zywicki had in her possession?
Did Zywicki have a St. Giles Soccer Club patch in her vehicle, and could this item help identify her movements or contacts?
On August 23, 1992, 21-year-old Tammy J. Zywicki left Evanston, Illinois for college in Iowa but never arrived; her abandoned car was found on I-80 in Central Illinois the same day. Nine days later, her body was discovered stabbed to death along I-44 in rural Lawrence County, Missouri. The identity of a tractor-trailer driver seen near her vehicle around the time of her disappearance remains unknown, and investigators seek information about this potential suspect and missing personal items including a camera and musical watch.
