Thanks for pointing that out.
If I remember correctly, one of the reasons the 'Native Americans' wanted to bury the K. man in such a hurry was that they were afraid the forensic investigators would discover what the 'Native Americans' feared they would discover: that the K. man was of Asian heritage, thus disproving that the 'Native Americans' were, in fact, native, and providing greater evidence that 'Native Americans' would be better termed 'Previous Settlers.'
But I'm writing this based upon a couple of articles I read quite a while ago.
Kennewick Man is related to the ancient Ainu/Joman Caucasoid people of Japan. There are many KM type skeletons all over the Americas. 9,400 year old Spirit Cave Man is the oldest mummy ever found in the Americas and looks similar to KM. The oldest Jomon skeleton found in Japan is 13,000 year old.
