I'd just point out again the gap between the appearance of the body in the slides and an answer to the question of 'what's really there objectively', which cannot be known without educated forensic examination the body itself (either in the present or, if that has been competently accomplished in the past, by reading the written records of such an examination, likely held in the museum's archives).
What's really there in this case is pixels/silver nitrate/colors on a slide positive. Interpreting the context using the data at our immediate disposal, we find a naturally desicated baby boy placed in a glass display case at a Park Service interpretive center, probably Camp Verde, Arizona, perhaps at Mesa Verde, Colorado. The boy's name is lost to prehistory. He never had a surname in our sense of the word. He had a mother and a father, and most likely both of them outlived the boy. The body is still there. If Chris KK really goes for it, we will find out more. DNA analysis will reveal he was a normal human boy, of the pre-Navajo/pre-Hopi Pueblo peoples called the Anasazi, likely with a large complement of pre-Dene invasion alleles. Speculation.
