I thought it could be a skull.
I'm sorry.
I am glad Karen's remains have finally been found, RIP Karen.
Having examined the image posted by TGY, I'm not sure that I'm convinced by what has been suggested to possibly be a skull, however in the same 9news video clip, there is some footage shot from overhead, that seems to be looking directly down upon the same two logs.
In this footage, there is some kind of commercially produced packaging, a lot of it dark blue/black and white between the logs, looking like a covering layer.
Is it possible that beneath the layer of smaller logs between the big logs shown in TGY's frame grab, was this layer of refuse, above the body? (Or vice versa).
The frame grab I have attached shows what I'm talking about & there is something that looks awfully like a human foot, complete with toes, visible. Perhaps the covering logs had been removed by this point in time & once the foot was visible, the remains were let untouched until the forensic team arrived? The footage was clearly taken yesterday afternoon, which would fit with this possibility.
