On August 23, 1992, 21-year-old Tammy Zywicki’s car broke down on I-80 in Illinois. Witnesses reported seeing a truck driver pull over. Tammy was last seen alive next to her stranded vehicle; her body was found days later in Missouri, wrapped in a blanket, with multiple stab wounds. Investigators suspected a long-haul trucker due to the interstate setting and witness accounts. The case drew national attention, but no suspect has been definitively charged.
