Just playing devil's advocate here. If a person really went sledding, they would probably return soaking wet - especially if they went sledding for three hours. They get home, take off all their wet snow pants, coats, etc, and they dump them on the floor by the door. Then, they go change. Josh comes back, sees the now-melted snow from the clothes all over the floor, and gets a couple fans to dry it.
I'm guessing it's something like that he probably told police.
The question would be - why not come in through the garage. But the wet spot seems a little like a red herring to me. It would seem that if there was anything damning in the carpet, he'd be arrested and in jail right now.[/QUOTE]
It's interesting that the word used to describe the spot is "wet" not something like "dark spot" or even "stained." It does lend itself to the possibility that the spot may not be blood.
