It doesn't make sense to me that JA would shower off while TA's body was in the shower too.
Wouldn't she just take a bath?
I can't understand how she got out of that bathroom without tracking blood through the house.
I don't know that she completely showered, not sure it was necessary since she was wearing clothes that she could just take off.
But her hair would surely have been bloody. So she takes the cup and rinses her hair while standing outside the shower.
Taking a bath takes a LONG time! Filling up a tub like that takes forever - especially when you are waiting to get in it...LOL!!
And I don't believe the police would have NOT tested the drain for blood. I just don't since they were trying to figure out exactly what happened. Yes, they had body and blood, but they wanted the complete story. I think we would know if blood if found in the drain.
We know she didn't really try to clean the scene...I mean, there is blood EVERYWHERE, and undisturbed for the most part. Look at the sink. Look at the floor. But at the same time, we know there was LOTS of water on that floor at one time since we see the boxes with the bloody watermarks on it going up the side - which means the boxes absorbed the water.
So for that water to get there, there had to be lot of water exposed to the bathroom AFTER the blood got there.
My explanation is that she stood outside the shower while Travis was in there and rinsed at the very least, her hair.
They have shown Travis was clearly washed off...so this fits to me.
It might not for you, and that's fine...just wanted to try to explain what I meant. LOL!!
