Unfortunately, I didn't found original article of 2002 from "Khakasia" paper, but above one have decent quotes from it.

Meanwhile fairy tales about princesses in crystal sarcophages that are sleepeng eternally are quite common, also Orthodox Christians believe in undecayable bodies of saints that kind of exist really, but not in chrystal sarcophages in liquid, and I heard about same thing, kind of bodies of monks that achieved full nirvana in caves that stay undecayed for centuries, but also not in sarcophages with liquid from buddhists.
So, there is at least some background exists for such phenomena.
Article that I think is closest to the source of that story - https://sibdepo.ru/news/tisulskijj-sarkofag.html (in Russian, use online translator)
