Playing Hooky
I have a personal experience, sort of. My father had a coworker who was a great guy. Good at his work, fun to talk to, nobody had any complaints about him. He lived in an apartment right next to work so the night watchman at the workplace would see him whenever he went out.
So one night, he went out in his pajamas, talking on his cell phone, nodded at the watchman. The watchman didn’t think much of it, after all, it’s not all that weird to take a walk even though it was quite late. He didn’t think much of it.
The watchman didn’t see him come back, but he figured he missed him when he went on his bathroom break. But the guy didn’t show up at work the next day. Someone from work went to check up and he wasn’t there. Nothing was disturbed, he was just gone.
Everyone thought he had dropped dead, killed by thugs or an accident or some medical condition. The workplace filed a police report. Here’s when it gets weird. It turns out, the guy had created a fake identity. Any credentials he had given were fake. The references he had given had never heard of him.
The family address he’d given didn’t exist. The police didn’t find anything illegal in the apartment, but they didn’t find anything that would give a clue as to who he was, either.
We moved away a few years ago, but I don’t think the case was ever solved. It’s definitely the best unexplained mystery that I’ve personally come across.
