I can't but the people at the museum can:
"A statement from Tara Travis, Ph.D., Supervisory Museum Curator, Mesa Verde National Park and Yucca House National Monument:
Recently we’ve received inquiries based on internet reports concerning the ancient remains of a human child which used to be on display in the Chapin Mesa Archeological Museum. We consulted with our National Park Service colleagues, who gave us this guidance: Out of respect for this child and his/her family, it was taken off public display many years ago. Although it was common practice in the past to display human remains in museums, we now try to treat them with the same respect we give to our own family members who have passed away.
There are many historical reports in the public domain of human remains that were recovered from various archeological sites in the Southwest in the early years. Interested readers can research authors like Dr. Jesse Walter Fewkes of the Smithsonian Institution and Gustav Nordenskiold. It’s important to remember that, regardless of how the remains were treated at the time of recovery, each was someone’s parent, child, and/or sibling. All should be treated with respect."
In other words: a new "investigation" based on the premise that the child in question crashed to earth on a flying saucer would be offensive.
Also why should scant resources be wasted because of dubious findings in two blurry slides? And why should access be granted to people that can't even work out its a mummy in the first place? or people that pretend that the slides have anything to do with Roswell.
Although I have never watched a full episode my understanding of the Ancient Alien theory is that the "ancients" had flying saucers rather than modern flying saucers being piloted by ancients, the idea of a mummy flying a saucer is beyond ridiculous, but maybe the crew of the saucer had just been on a museum robbing trip and had stowed the mummy on board before they crashed?
