A quarter century after Iowa college student Tammy Zywicki was abducted in Illinois and found murdered in Missouri, authorities again are asking for the public's help in trying finally to solve the case.
Illinois State Police and the FBI issued the appeal Tuesday, one day before the 25th anniversary of the 21-year-old Zywicki's disappearance. The FBI is offering a reward of up to $50,000 for information leading to any suspects.
Authorities say Zywicki was driving from her New Jersey home to Iowa's Grinnell College for her senior year when she was last seen alive near her disabled 1985 Pontiac T-1000 along Interstate 80 near LaSalle in north central Illinois.
Her body was found with stab wounds a week later wrapped in a blanket in southwestern Missouri east of Joplin.
Authorities say some of her personal property is still missing, including a Cannon 35mm camera, a Lorus brand musical wrist watch with a green umbrella face and a green band (it plays "Raindrops Keep Falling on My Head"), and a shoulder patch from the St. Giles Soccer Club in Greenville, South Carolina.
