That movie has crossed my mind as well when thinking of this case.
Curious what significance the shower had in her warped mind. One thing to begin the attack there, but to drag him back when obviously there was further bloodshed outside of it? The only thing that comes to mind is some sort of total humiliation, of him being found in such a vulnerable place?

Hi, Panthera. I think that it's a combination of the rational (wanting to wash off her DNA from his body; placing him in the room least likely to be entered) and irrational (cleansing his body to remember him as he was.) Cleansing forms a vital part in Mormon rituals (as it does in other sects) and it's possible that Jodi was still clinging to her newfound faith in a characteristically twisted way.
