I think those barbells are very close to a bloody footprint and that DG's shoe, with KL's blood on it, touched one of those barbells while he was doing something in the garage. I do not think those barbells were ever moved from their original location or used to hit anyone during this crime and I do not think either KL or AL were ever in the garage during the course of this attack. Weren't they dragged out a side door and taken to the driveway?
I wonder what DG was doing in the garage? Looking for something to cover the back of the pick up truck with? Or to put the victims in to minimize the blood evidence in the back of his truck? Since the Liknes' were moving, what might they have had in the garage that may have been used? Would JO have known what might have been missing from the garage? Did they have anything packed into a large box or crate? It sure looks like something large and square in the back of that truck in the pictures. I also find it hard to believe with all his research that DG would bring a white tarp to cover what was supposed to have been two restrained adults.
I also don't think that anyone had to hit DG in the knee for him to have gotten that injury. Considering what he did, hauling two large adults around, in and out of the back of the truck and using sharp weapons I'm surprised he didn't have many more injuries than he did.
MOO
