They've searched all around the houses and outbuildings, and with dogs, too, right? Can dogs be trained to alert to blood? I would think that any disturbed or stained surface or area would have been investigated, so does that mean that whatever foul play was involved with Gus, did not involve blood? What could that be - closed head injury, drowning in a scant amount of water (I know of a toddler who drowned in a 5 gallon bucket, for instance), hot car death?
Also trying to think of how the original account of the hours leading up to the reporting of Gus's disappearance was inaccurate, but in a way that Jess was unaware of its inaccuracy. It doesnt reflect well on either grandparent.
