Welcome back to Scary Things! This week, I want to hear about a real-life murder mystery that gives you the severe heebie-jeebies (I'm sure all you lovelies would already do this, but not too gory with the posted details unless you give a trigger warning and go below the fold - links are better). For me? The Hinterkaifeck murders. The fact that they were never solved is creepy enough, but the footsteps leading to the farm from the forest and not back, the previous maid quitting due to thinking the farm was haunted, and the evidence that the killer was there for some time after the murders all combine to make this just about the creepiest real-life murder mystery ever.

What real-life murder mystery freaks you out?
