Alexander Bychkov was arrested and charged in central Russia with murder and cannibalism, RIA Novosti reported Monday.
Police said Bychkov had been arrested for theft from a local store, but during questioning he allegedly began talking about corpses buried near his house in Russia's Penza region.
Six bodies were recovered and sent to a lab for examination.
Police said the suspect identified the photos of those who died.
Investigators said they believe Bychkov killed his victims with a knife, then cut them up and ate their livers.
