To me Wayne has so many stories he packed into the event but none have much detail if they were his own experiences. I thought it odd that he’s been to the Sievers residence multiple times and even ridden the motorcycle before, that he would be out checking it out. So I have a different theory.
I think those things sound like what I would expect from JR, never being in the house before. I think JR was in the garage looking at the motorcycle, and when Teresa drove up he hid. I think CW was in the pantry. I think CW attacked Teresa, and struggled getting her down. I think JR came in when he heard the commotion and kicked the dog bowl. I think CW hit her with the hammer while she was on the ground. I think JR said thats enough. I think JR cleaned up the mess. I think when they got out of there, CW said where were you? and JR told him he was looking at the motorcycle when she opened the garage door. I think this murder was planned and they are both guilty. But I think CW is telling JR’s story.
Maybe I’m wrong, idk.
