Moscow (CNN) -- A historian has been arrested in central Russia after police found the corpses of 29 women, dressed as dolls, in his apartment, authorities said this week.
The 45-year-old man, who police did not identify, has been charged with desecrating bodies and graves, officials said.
Video released by police showed an eerie collection of what looks like life-sized dolls, outfitted in shabby dresses and headscarves, their hands and faces wrapped in fabric. Authorities say the man also stole clothes from the graves when he took the bodies.
Russian Interior Ministry spokesman Gen. Valery Gribakin told CNN police couldn't figure out for a long time who was behind the "numerous blasphemous acts against the graves and the dead bodies" at several cemeteries in and around Nizhny Novgorod, about 250 miles east of Moscow.
The incidents started about two years ago, authorities said, with each case producing a public uproar in the region. Gribakin said police went the extra mile to find the culprit.
"Our leading theory was that it was done by some extremist organizations," Gribakin said. "We decided to beef up our police units and set up ... groups composed of our most experienced detectives who specialize in extremist crimes."
But even seasoned investigators and forensic experts were shocked when their investigation led them to the historian and the contents of his apartment, where the women's mummified bodies were found. The corpses were those of women who died between the ages of 15 to 25, officials said.
Gribakin also said during the search the police found "photographs and plaques from gravestones, doll-making manuals and well as maps of local cemeteries."
Police said the man is a well-known historian specializing in Celtic studies who authored many books and articles, and used to be a college professor at some point.
State-run RIA Novosti and local media in Nizhny Novgorod identified the man seen in the police video of the crime scene as Anatoly Moskvin, a resident of that city. Russian journalists have retrieved articles written by Moskvin in local newspapers from the past several years, indicating his profound interest in and great knowledge of all cemeteries across the region.
The suspect faces charges of desecrating dead bodies and their burial sites, a crime punishable by up to three months in jail or a year of correctional labor.
