Strange goings on in Shropshire

Just found a third body. Looks like he did them all then!

And two other dogs are missing. Its possible that the body of the daughter and maybe the two dogs are in part of the building that hasn't been searched fully, but I would think it unlikely. I think the daughter is involved somehow. Maybe she snapped with the prospect of losing everything, as the house was on the brink of repossession. But would she have been able to move the horse box over the driveway?? All very odd.
