Anatoly Moskvin is a Russian former linguist, philologist, and historian who was arrested in 2011 after the mummified bodies of twenty-six girls and women between the ages of 3 and 29 were discovered in his apartment in Nizhny Novgorod. After exhuming the bodies from local cemeteries, Moskvin mummified the bodies himself before dressing and posing them around his home. Moskvin’s parents, who shared the apartment with him, knew of the mummies but mistook them for large dolls.
I’m taking it that his parents were elderly, and could not ever dream of their son doing such a thing.
But their son having 29 human sized dolls was just fine and not weird at all
