Attention all couch detectives! The FBI is hoping you can help them out.
In 1992, Tammy Zywicki disappeared. The Iowa college student was driving from her home in New Jersey to college when she was last seen alive on August 23, 1992. She was standing next to her broken-down Pontiac T1000 on the interstate.
Her car was found abandoned by a state trooper that afternoon, and that evening her mom reported her missing.
Zywicki's body was found a week later in Missouri, wrapped in a blanket and covered with duct tape. She had been stabbed and strangled.
Witnesses say they saw Zywicki on the interstate, with a tractor-trailer parked behind her car. Others say it was a pickup truck, not a trailer.
The FBI worked with state police to form a task force to try and solve Zywicki's case. They looked at any possible relations to other cases. Any truck or tractor driver suspected in other murder cases or sexual attacks were looked at. The search spread from California to North Carolina, but nothing showed up. One year after the investigation started, the task force disbanded.
But now police think they might have a lead, and they need your help.
