If I were to guess, I'd say he killed her in her sleep. She was pissed and left work because she blew his cover, she probably threatened to leave him, and he was about to be exposed to be the loser jackass he is. I know they haven't proven him guilty, but he didn't do a very good job of hiding that from the start. If he loved her and was inncoent, he'd have been out there in the dump looking with the rest of the volunteers instead of checking himself into a mental institution asking family members to bring him video games to pass the time.

I hope the lights dim in Utah when they roast that ****er.
