Jailed Russian serial killer rapist dubbed “The Werewolf” who murdered 83 women volunteers to fight for Putin in Ukraine.

Russia’s most heinous serial killer rapist has volunteered to fight in Ukraine for President Vladimir Putin.

Mikhail Popkov, 58, is a sex attacker who wants to join a controversial scheme in which thousands of murderers, rapists, and other hardened criminals have become mercenaries because Putin pardons those who fight and survive for six months.

Popkov, dubbed “The Werewolf” and “Angarsk Maniac,” murdered 83 women and is serving two life sentences plus nine years in prison after three separate trials.

According to a police source, his true tally is ‘closer to 200’.

Popkov raped the majority of his victims, who ranged in age from 18 to 50, before murdering them with axes, hammers, knives, screwdrivers, and spades.

He pleaded to join Putin’s fighters in a state TV interview from behind bars, claiming radio-electronics experience from his time as a Red Army conscript.

He hopes to use the sickening Kremlin scheme which has freed as many as 40,000 convicts to gain his liberty.

‘What is your dream?’ asked Russian state television.

‘To join the army,’ he replied.

The mass killer said: ‘I would not hesitate to do so [join the war].

‘If I refer to my military registration profession, I think it’s in rather high demand now…

‘Though radio-electronics is probably more modern these days…’

‘However, even though I’ve been in prison for ten years, I don’t believe it would be so difficult to learn [new skills] quickly.’

Married father-of-one Popkov conducted a reign of terror against women out alone between 1992 and 2010 in his home city Angarsk which he wanted to ‘cleanse of prostitutes’.

Popkov was diagnosed with homicidal mania after a psychiatric evaluation, which is defined as “a condition in which a person has an irrational desire to kill someone,” according to TASS.
