Not that I've seen. OPs have opined one of the girls fought back and maybe kicked his nose, causing a nose bleed. Or perhaps he was injured 'cleaning' an animal or fish he killed. I don't think we know how old or fresh his blood in one handprint was.
With this renewed focus on the DNA samples taken from the two bloody handprints on TD's truck, I don't believe we've received an update on the animal blood found in the second handprint.
If one handprint was TD's blood, what animal's blood was in the other hand print? IOW, I presume TD had the blood from an animal on one hand.
It truly may be a moot question, but IMO, it remains unanswered by LE. Some here thought TD's dog had been injured and TD had its blood on his hand. But the shelter pics of TD's dog from MSM did not indicate any injury to me.
Was the hand print with animal blood simply a print following an old hunting or fishing kill?
Or was it recent, possibly indicating whether TD lived a day or two at the campground after his girls were dead? Or could recent animal blood indicate he prepared to be on the run by killing and cooking fish or other game?
Seems like a waste of time to ask such questions, since it really may not matter or perhaps cannot be answered. But my sleuthing mind is curious.
IMO
