On November 17, 1978, four young employees began the night shift at the Burger Chef restaurant in Speedway, Indiana. By midnight, they had vanished, never to be seen alive again. Two days later, their bodies were found in a wooded area in Johnson County.

But who killed Jayne Friedt, Ruth Shelton, Danny Davis, and Mark Flemmonds? Last year, the Murder Sheet launched an investigative miniseries on the case: "You Never Can Forget." This year, we're dropping more episodes, and taking an even closer look at this heinous crime.
