Not me.
This is how I picture it ...
Travis says Goodbye to Jodi.
He is going to have a shower after having sex, and believes Jodi is off to SLC to see RB and see/visit other Mormon members.
Jodi goes to her rental and comes back in the house and starts taking photos of Travis in the shower with his camera - to add to the collection of sex photos, to frame him with his Bishop/Mimi.
He sees her, she has the .25 caliber gun she "stole" from her grandparents.
She fires out of white rage - misfire.
Travis "leaps" towards her and she shoots again. This time, the small bullet goes straight down and misses his brain.
He is tough.
He stands in front of the sink, blood spattering from his sinus cavity trying to comprehend what is going on.
Jodi has culinary knife on hand and starts to stab him in the back.
He faces her - in a split second, a stab to the heart.
He is tough.
He turns around to face with his hands up, and tries to fight her off.
After 1 minute, he drops to the ground and starts to crawl towards the exit.
He makes it to the end of the tile hallway - throat slit. All in less than 2 minutes.
