Hi everyone, I've lurked this site for years, and finally joined due to this trial.
Anyway, here is a scenario about what happened at the shower that makes a lot of sense to me. Its the one that I can most easily visualize, and I think it matches the evidence.
Travis is in the shower and he thinks Jodi has left. While he is in the shower, he discovers she is there, taking photos of him. I think he is startled, by the picture where his head is turned toward the camera and he looks somewhat shocked. I think he was irritated with her. She may have opened the door and got him to sit down when she took that last pic of his face.
I think he then stepped out of the shower, grabbed a towel, probably made some comments about her needing to leave, why are you still here, etc., and as his arms are up, and his eyes momentarily covered with the towel, she stabs him in the chest.
I believe the wounds on his chest were from a slightly lower angle, so this would fit. Also, he would be standing there with his chest exposed to Jodi. I think once the attack started, I am not sure how many other moments he would be in a position to get those direct stabs to his chest from a slightly lower angle (as opposed to coming from above).
It seems like this would fit into the time frame as well. She must have dropped the camera right around the time of this first stab at him. Then it just progressed from there.
Any takers on this one??
