What is the strangest mystery that is still unsolved? from r/AskReddit

An unknown group of people broke into an FBI building, and no one has found out who they are. But the best part of the story is, they did it by leaving a sticky note that said “Do not lock the door tonight” and it worked.

Imagine being the guy who left it unlocked

Last one out was the most rotten egg, though.

This is my favorite weird and barely known one:

Back in 2013 an unknown group assaulted a power substation in California. By all appearances it was pretty sophisticated: scouted firing positions, all casings wiped of prints, they targeted transformers so they’d take time to overheat before triggering any alarms, also knew exactly when the police would arrive.

No suspect or motive to this day, they also cut some fiber optic cables in a vault nearby. Conspiracy types think it was a dry run by Russia or possibly China to see how effective an attack like that might be.

What kind of Transformers, Autobots or Decepticons?

Since the mystery was never solved, I’d say it’s the perfect Optimus Crime.
