I very much think JW thinks he "saved" S, or at least uses it justify the murders b/c he's not sorry. He's not once said it in a way that I believe that he is. Look at his story at DR's. Doesn't make sense.
They found a shoe print. Yet, it can't be placed on either of the three men's feet. What I find odd though is that three men enter the home, and instead of one each taking a room. They just stand there playing rent-a-guard, while it's JW who sees DR and HR through their closed bedroom doors, (he even peeks under the doors), and then they see him. He shoots DR in the head, through a closed door, and, with a light, as bright as that in the courtroom, he sees HMR, preparing to feed the baby. She looks up JW shoots her. Compassionately /s rearranges her body so the infant can seek to nurse (I guess he thought they're like pups and that deceased women continue to produce milk), he then proceeds past his armed rent-a-guards, to murder CR2. What is not right with this picture? Get in, get out, one man takes one room each and they're gone and out of there. I call that whole story B.S. does it matter to the jury that it's full of holes? Idk.
