The 64 year-old told Russian investigators that he used a saw to dismember the bodies.
He claims to have gotten his inspiration from horror movies.
He boiled the severed heads on a gas cooker and later flushed other body parts down the toilet.
This caused a blockage in the sewer system of the building block where he resided.

The plumbers then alerted police, who managed to trace the crime to a flat where the man confessed to killing the couple he shared the apartment with.
He told the officers that his housemates were ‘alcoholics’ and he was fed up of their frequent partying.
The killer claimed he had no criminal record, but police are investigating whether he ate his victims after boiling their heads in a saucepan.
