Hiya geevee!
I've thought about the Arias case as well. But the difference is, in that Travis was trying to run away from Jodi. Jodi didn't have him pinned down and stabbing him. And even then, even with him running away, he did have defensive wounds on him. Very obvious ones. Remember his hands? Large cuts? Bruises on his legs, etc.. It was very obvious there was a struggle. He first defended himself, and then tried to get away.
But what about the two knives? Like they said in the report, that means Rudy would have had to set one knife down, then picked up the other, it just doesn't make sense. Also I have a real problem with the no defensive wounds. So Rudy obviously needs 1 hand to hold the knife in. That leaves only 1 hand free on Rudy. Let's say, with 1 hand he is able to somehow hold both of Meredith's hands together so she can't use her hands. That leaves her feet open. She would have been kicking. There was also Meredith's hair in clumps on the floor....if Rudy was holding her by the hair to restrain her, that would leave both Meredith's arms and legs free. I just don't see how it's possible with only Rudy. If her hands were at any point free, they would have defensive cuts on them like Travis' did, from trying to shield herself from the knife.
I suppose he could have sat on top of her legs and pinned her down with his legs, then used one of his hands to hold her two hands together. I don't know how possible that is or how much strength he would have needed to do that. And that doesn't explain her hair clumps on the floor. That also doesn't explain how or why there were 2 knives involved.
Then there is the issue of the window staging. IMO, there is no way he could have gone though that window (let's assume he was somehow able to climb up to the window, though I find that improbable), without leaving signs that he went through that window. I just don't find it believable at all. There would have been no question as to whether it was a staged window or not. Climbing all the way up from the first window, I don't believe he could have done it by using his hands and then pulling one foot up on the window ledge. I believe he would have had to pull up with his hands and kind of lunge through the window. And then the glass on top of the clothes.
It just doesn't fit. Nothing fits or makes sense!
