The dead body on the deck has actually been investigated. When they interviewed the owners of the property, it was determined that someone had gone for a swim, and the discoloration of the deck is where it's wet, from the water that had dripped from the swimmer.
Not saying I believe it's blood but that seem like way too much water from a swimmer walking down the deck.
