A Russian serial killer known as "the werewolf" killed as many as 81 women, according to police.
Former Siberian policeman Mikhail Popkov, who is serving a life sentence for murdering 22 women, has confessed to 59 new killings, according to the Russian Investigative Committee (RIC).
The RIC, Russia's equivalent of the FBI, says Popkov told them he had killed the women during a rampage which ran from 1994 to 2000.
The women, aged between 17 and 38, were raped before being killed with axes, knives or screwdrivers.
The new death toll would make Popkov Russia's worst serial killer, with more victims than Andrei Chikatilo - the "Butcher of Rostov" - who murdered 53 people, and "Chessboard Killer" Alexander Pichushkin, who killed 49.
