If I’m not mistaken, this article mentioned no method of identifying the Falling Man except the color of his skin and how he was dressed. Weren’t DNA and dental records ever used to positively identify him?
I don’t know if you’ve seen the pictures of the areas these people fell onto, but the impacts in some cases left nothing but large red splatters. On top of that, not that long afterwards, several hundred thousand tons of concrete and metal came crashing down on the same areas, burying them.
It would have taken an utter miracle to do a DNA match or find a tooth after that.
