Cliff dweller

I don't know if someone has already addressed this, I don't want to take the time to read all of the posts. But, could the dead body that we saw in the water have been the man on the boat who jumped off? The foot looked more like a man's foot than a woman's, and Tanya was wearing her shoes when she fell into the water, and I don't think the fall was enough to knock off those shoes. So, perhaps Tanya survived?
