There are quite a few ghastly stories of corpses discovered out in the open long after their death. How could a dead body be hiding in plain sight? In most cases, people believe it's part of a gag or an elaborate Halloween decoration and do nothing about it.
Most people don’t expect to casually come across dead bodies in public, but it has happened. And while some argue calling the police for every scary body prop you see is a bit of overkill, when you realize that actual bodies have gone ignored in the past, the inconvenience of calling the police officer is far better than the alternative. Because sometimes what seems like a harmless decoration or a silly act can actually be quite deadly.
