I still say the photos that were on the camera in the washer were intended to expose him. They may have been deleted by Travis before he went into the shower and so she was forced to take more...the photos of him in the shower. She probably told him that she was going to expose him and what they had been doing all along to his friends and the church and he was to the point to where he simply had no fight left.. and he just didn't care anymore *(thus the look on his face in the last picture of him alive)* He may have attempted to grab the camera, causing it to fall to the floor and she perceived it has an attack on her... I wonder if she will tell all.. the whole ugly, bloody truth?
I often wonder if that look in the shower was him just giving up....I also think she was going to expose him in some sort
