In the summer of 1978, someone got away with murder in Norristown, Pennsylvania.

A carnival lit up the night. Music, laughter, bright lights—and by morning, a 17-year-old girl was found murdered, her body left in a local park.

Investigators have long believed her death may be connected to the carnival she attended just hours before she was killed.

Telling her story keeps her name alive. It ensures she is more than a headline, more than a cold case.

This is the story of Norristown Area High School senior, Michele Evanik.
