David have you thought any more about June's position when she sustained the two gsw's to her head? There's no need for me to keep reposting the graphic image we are all familiar with. I have lined up the rifle against the door, ie barrel over June and pointing out onto the landing, and then rotated it around based on the wound tracks and I can only get the casings on the landing? I'm sorry but your casing ricochet just doesn't work as there's no evidence they have the sort of velocity required to travel the distance. The 'Farm Girl' vid shows the sort of ricochet involved. Although the casings are significantly larger they are heavier too with the inevitable drag so the net effect should be about the same. They only require enough energy to eject them quickly enough to cycle a new round.
Given June was incapable of voluntary movement after sustaining either gsw to the head I'm struggling with any involuntary movement and casings. If she was sat up against the door when shot the the flight of the casings would be impeded by the door and they would ricochet back and land around her hand near her waist? I can accept 1 could do somthing very random but not two. Research shows for a variety of reasons 25% go astray so at least one should be where anticipated based on the ejection pattern. This is borne out by the casings that pertain to SC unless she was moved significantly.
