You might have heard about this because it was a famous case but in the 70's less than 10 miles from where I lived a girl scout troop was brutally murdered. I grew up hearing about this event and it always scared the crap out of me, especially listening to some of the full blood Native Americans who thought that a shape shifter did it. This was literally like something straight out of IT or Black House. There's a book about the murders but it's hard to find, my mom had a copy and she had to pay a couple of hundred bucks for it. Google Oklahoma Girl Scout murders and you'll see what i'm talking about.
