The Smithsonian Institution lost her body after dissecting it in the late 1800's.

So, how does a prestigious institution "lose" a body? I'll bet it "found" its way into a private collection, for a consideration.

There’s a story about the Smithsonian towing a bargeload of inconvenient artifacts out into the Atlantic and dumping it, early 20th century.
