Sometimes, I imagine a reality where I'm not driven by insanity to keep the bodies of prostitutes in my shed,
We can't always get what we want.
It would help if you dug a hole. More volume, more space to store prostitute bodies, and to top that off they're still in the shed.
If not, you could always store the prostitutes in someone else's shed so that he takes the fall. Of course, trying to smuggle prostitute bodies at night is a bit suspicious, but you get used to it and you could find good routes. Of course the guy is going to get suspicious that there's dead bodies in his shed, but then you will have to start with those that don't go to their shed as often, then go to multiple neighborhoods. At this point everyone is a suspect, but your shed will be clean and so the police will get all confused long enough for you to get a nice quota.
Oh wait, were you talking about curing your OCD for prostitute corpse stashing?
