And blood is considerably more slippery than water (thought JA may not have known this).
My theory remains the same: The water on the bathroom floor was due to two (maybe three) factors:
-Travis getting out of the shower and moving around (for a short while, at least) soaking wet, without toweling off -
- Possibly JA's attempt to move Travis more easily (but I think it would prove unnecessary, especially with the amount of blood continuing to bleed from Travis.

.
- JA realized there were clear footprints in several areas of the floor (that weren't splattered with water coming from Travis' body) and she didn't know if any of them were hers (even if she was in socks, the size/shape of her foot could be matched with a clear print - not perfect, but LE would determine pretty quickly the footprints were Travis' and that of a female, about 5' 5" in height.
I believe she poured water all over the floor to eliminate recognizable prints. There weren't any prints of Travis' either. The only 'footprint' found was that partial sneaker (?) print near the closet - who knows what that was about. I don't believe JA was wearing sneakers anywhere in that bathroom area. Do we know if all of Travis' sneakers/shoes were accounted for? Don't think the state needs to go down that rabbit hole

- because they didn't.
The blood spatter on the sink and the mirror wasn't diluted and the edges were crisp - *except* for the space between the sink bowl and the counter top edge, where it looks to have been smeared. I think there were probably clear prints there, and again, not knowing if they were hers or Travis', JA diluted them with water. The area looks 'swiped'. But the spatter, spray and drips in the sink bowl and on the mirror were ignored - left undisturbed and pristine.
There was at least one wide swath/wipe on the wall in the hallway, which could also be JA wiping a towel along the hall to eliminate (not blood) but prints. She missed one, thankfully.
That's my theory about the water, fwiw.
