It's that time again, /x/.
Put on your trench-coats and Fedoras and light up a cigarette in a dimly-lit office with a shot glass of fine liquor, it’s time for a creepy unsolved crimes thread.

I know we had a thread like this semi-recently, but people enjoyed it even more than usual, and it seemed to end a little prematurely. So, what’s the harm in trying again? Maybe this needs to become a more regular event on /x/.

Unexplained disappearances. Perpetrators vanishing without a trace. “Suspicious” suicides. Bizarre, ritualized murders and messages from an anonymous killer. Indecipherable pieces of evidence. Incomprehensible acts of theft and terrorism. Horrific acts of violence with no apparent motive. Inexplicable or even supernatural elements to crime that defy conventional understanding. Tales of corrupt officials and conspiracies, tampering with evidence and suppressing the truth. Abduction, torture, ritual-murder, human-trafficking, secret societies and more.

Rookie Mode: Post a Wikipedia link.

Veteran Mode: Post a Wikipedia link AND a green-text summary in this thread that explains why the crime/event is so creepy, and inspires people to go and read the Wiki article.

As per usual, I’ll post some great copy-pasta from the previous iterations of this thread to get things started, and to keep this thread alive if things get slow.
