Y'all please help me figure out which way Travis was facing in the shower when found, because there is no way in h*ll I'm going to look at that horrible picture again.
I keep thinking about this case I read about where a girl who didn't even commit the murder mutilated the body of her obsession's girlfriend after he had killed the girlfriend. She basically did target practice on the gf's head long after death (and decapitation). It was just to be mean. There was no doubt it was after the decapitation because of where the bullet was fired into.
So, I'm thinking JA is about to wash off in the shower, and she's still angry and maybe freaked out about getting into the shower with Travis' body. She went to all that work to get the gun according to her plan. So she gets the gun at that point and takes it into the shower with her. That's when she shoots him, as a big final F-U to Travis, mainly. She's standing in the shower, facing Travis. Then she just tosses the gun aside and washes up, washes him off, etc.
Doesn't that work with the distance the gun was fired from, the trajectory through Travis' head/face, and where the shell casing landed?
