I see that line of blood more an indication of what Jodi did with the water. Those aren't passive drops. Passive drops are clean roundish drops. That blood has been disturbed by water, and is not in its original position from initial deposit on the floor.
What I meant by 'passive' drops is that the blood stains are not all over the place in random fashion, but follow a line, suggesting that the blood source was no longer involved in a fight, but was immobile and being dragged in a straight line.
In attachment 1 below, the blood trail leads directly from the location of the huge blood pool on the carpet. While one can invoke various scenarios, the simplest explanation is that a dead Travis was being dragged from this location on the carpet to the bathroom.
As far as the effects of water, when blood spills on a surface and is allowed to coagulate for some period of time (such when Jodi was stuffing Travis in the shower), throwing some water on the floor is NOT going to cause the spot to move to a new location. It may remove some of the un-coagulated blood and spread it around in dilute form, smearing edges, etc., but the basic blood spot/stain will remain unless someone start scrubbing (HARD) to remove it.
I think the photo in attachment 2 shows this. The variegated blood stains on the floor are from the water removing
some of the blood from the floor stains, diluting this soluble blood, and then the water dries on the floor and leaves this appearance.
What you
don't see in attachment 1 is the variegated appearance suggesting that there was much blood solublized by the water. What you
do see is some smearing of the blood stains along the blood trail. But the blood trail is clearly there. Its pretty obvious to me that this blood trail was likely left when Travis was being dragged back to the bathroom.
Sure, it's hard, that's why she gave up. She didn't clean it all or even most of it. But it does appear she did clear off that area in front of the carpet. He would have been moved over that area going toward the carpet and going back toward the bathroom.
Per above. There is clearly some smearing of the blood spots by water, but I don't see any indication there was a major effort by Jodi to get on her hands and knees and scrub this floor down. I agree, she gave up, probably quickly, when she realized how hopeless the task was. But the story of the blood reads like a good novel and it remains intact, despite some smearing by Jodi's passive attempt at cleaning up. It all fits together perfectly like a jigsaw puzzle. You may disagree, but I don't see any missing pieces!
A final thing I would add regarding whether Travis bled out on the tiles prior to the 'foot' and 'dragging' photos, or bled out on the carpet at the location of the major carpet stain: one has to ask whether there was arterial pressure when this carpet stain was made, or had Travis' heart stopped beating prior to the carpet stain. The heaviness of this stain and the indications of arterial spray suggest Travis had blood pressure at this location. If Travis had bled out of two severed carotid arteries prior to the 'foot' photo, and been allowed to bleed out for a minimum of 76 seconds (prior to the 'dragging' photo), he would have had zero blood pressure and his heart would have stopped prior to the carpet stain. There would have been some passive flow of residual blood, but no blood being actively pumped from the wound.
