I thought of this while I was getting gas for my car.
There was a smiley face drawn on the base of the gas pump and a young male mysteriously drowned last summer not far from it.
The guy wasn't even local and had no reason to be here.
It's a fascinating idea, but it doesn't sound like there's a whole lot of evidence.
If you wanted to drown people, though, waiting near a body of water near a bar on a friday night would be a pretty easy way to ensure yourself a lone, drunk victim would wander up sooner or later.
