There are a lot of true crime stories that are so infamous it feels like evveeeerrryone knows about them — Jeffrey Dahmer, John Wayne Gacy, and D.B. Cooper...the list goes on.
But on the flip side, there are actually many true crime stories not a lot of people have heard about before.
For example, have you ever heard of the "Hangman" or "Killer Cop," aka Gerard John Schaefer Jr.? He was a former sheriff's deputy and suspected serial killer active in Florida in the '70s.
Or did you know about the unsolved Santa Rosa hitchhiker murders that took place from 1972–1973 in Northern California?
Perhaps you've gone your whole life not knowing that the R.E.M. song, “What’s the Frequency, Kenneth?” is a reference to the 1986 crime where CBS Evening News anchor Dan Rather was attacked and mugged by two men while one of them repeatedly said, "Kenneth, what is the frequency?”
