The unsolved murder of 21-year-old Tammy Jo Zywicki of Marlton, N. J., is relived in a Philadelphia Inquirer article that was syndicated through Knight Ridder's services.
Miss Zywicki, you may recall, was returning to Grinnell College in 1992 when she stopped her car on a a shoulder of I-80 near LaSalle, Ill. The last witness who saw her said the hood was open on her car and a tractor-trailer driver, about 35 years old, was standing beside her.
Nine days later, her body was on I-44 near Joplin. She had been stabbed to death and was sexually assaulted, according to law enforcement officials.
