UPDATED: Who Killed Jeannette DePalma?

In this all-but-forgotten unsolved case from 1972, the body of a teenage girl was discovered atop a cliff, high above an abandoned quarry in the town of Springfield. The corpse was found thanks to a dog that brought home a badly decomposed human forearm to its master. The deceased would later be identified as Jeannette DePalma, a local teenager who had been missing for six weeks. Before long, witchcraft, satanism and police conspiracies would all become suspects in the bizarre case.
