Was working in the den and had a rerun of Law and Order on for background noise. The detectives executed a search warrant, went to the plastic bin next to the hot tub and found .... CHLORINE!!!
The spa owner was convicted of murder in short order. Or maybe it was the hottie in the tub with him taht was convicted. Sorry, like I said, I was trying to work.
But it all makes sense in a weird sort of way, doesn't it?
