An 18-year-old leaves work to run an errand and never returns.

In August 1973, Teresa Osborne disappeared after picking up pastries from a bakery in Seymour, Indiana. Ten days later, her body was found in the trunk of her burned car in a remote wildlife refuge.

Investigators interviewed hundreds of people and followed countless leads, but no one was ever charged.

A detail uncovered months later suggests Teresa may have been afraid of “some man or men” before she vanished.

More than fifty years later, her case remains unsolved.
