She said this in an interview with Izvestia.

“An investigative experiment refuted the version that the bodies of the dead were destroyed using sulfuric acid and fire,” Molodtsova said.

According to her, although this version was previously reproduced in various literature and publications, it was possible to establish that "applying concentrated sulfuric acid to the surface of biological tissues slows down the process of their subsequent burning."

She also added that another experiment, in which in a room with the same dimensions as in the basement of the Ipatiev House, the conditions and circumstances of the execution of the family of Nicholas II were reproduced, refuted the arguments that 11 victims could not accommodate in such a small room participants in the execution.

In January 2019, an envelope with rare photographs of the Russian Emperor Nicholas II and members of his family was discovered in Essentuki.
