Yes, I think maybe the purpose of resetting the dates on the pics was twofold.
1-to get Travis in trouble with his girlfriends and ruin his reputation forever. This was the main reason as she was very vindictive and it wasn't good enough just to kill him.
2-to leave the pictures on the camera as proof of Travis liking her so she would not be a suspect in his murder. She would have to make the dates old enough to be back when she was known to last be there.
I think what happened is she had too much trouble with the dates and it was taking too long messing with it and so she then tried just deleting them all but the thumbnails remained.
I think she may have gotten some blood drops or stains on it too in the nooks and crannies and I think she intended on taking the camera with her OR tried to wash the camera and was going to put it back after the wash cycle but just plain forgot about the camera in washer.
I do think the time was getting late and she began rushing towards the end and she started to panic to leave.
Watching the interview with detective when he tells her about the pics is hilarious seeing her reaction. She never expected any photos to be on the camera. She thought she had deleted them all. And if I remember right she seemed to be hinting that the dates could be manipulated on the pics which is a sign she had fooled with the dates.
Travis bought the camera after she left Mesa, and she didn't return there until June 4th to murder him. So, she couldn't plant nekked pics on his camera without incriminating herself.
So, one question has been if she could have used a memory stick belonging to TA, without realizing there were nekked pics on it.
She did take those pics of Travis in the shower on the 4th, though its possible the timestamps are incorrect.
Assumption- he knew she was taking the pics. Why would she want to take them? Most logically- to place herself near the shower without making him suspicious.
Assumption- he didn't know she was taking the pics. Why would she take them? As trophies for herself? To suggest TA had been intimate with his killer, no evidence that it was she?
