The big question is under what shelter did she “manipulate” his body to fit into a suitcase? Had she hauled it into a storage unit she would have needed help and video would have captured it. Had she dismembered him out in a remote outdoor location, where no one could ear a gunshot, (or did they) that would have been risky and left a lot of blood. Wherever she did this there must have been blood and potentially witnesses.
4 hours is not a lot of time to drive at least an hour north and back, stop at stores, shop, find a remote location where there are no witnesses, kill someone, dismember or somehow manipulate them enough to fit them into a suitcase, which cannot be an easy task, rent a storage unit, haul suitcase into unit and drive back in time to clean up and play nice with LE when reporting him missing. I don’t buy she hauled him herself into some unit and went back later to dismember him and stuff him in suitcase. The only way she’d have gotten him into a unit alone and undetected, would be in a rolling suitcase to begin with. Nor do I buy she shot him and left him out somewhere in the cold only to return later to dismember him. WAY too risky. Coyotes, bear, mountain lions, humans, vultures, etc. not to mention cops and others watching her movements. Way too risky.
I wonder if enhanced video shows the exact initial injury site on G. Eye, head, stomach, face, etc. I wonder if the suitcase was in truck when she returned home. She did say G came back home with her. If so, maybe she left again to stash him away somewhere after girls went to store.
Anyway you look at it, if G’s body was at any time in the back of that truck, no amount of car washes could have cleaned away the blood traces. And regarding the knife/saw/sharp object: did she get it at Lowe’s next to Petco. Did AS notice it missing from garage. Was it back in garage but lit up with luminol.
