RUSSIA’S most wanted serial killer who “raped and murdered 100 women” could be dead as cops find a body that could belong to him.

Police are investigating whether a corpse with a mouthful of gold teeth found in a quarry belongs to truck driver Valery Andreev, the country’s “most wanted” killer.

Andreev is feared to have raped and murdered more than 100 women, but has never faced trial.

Known as the Orsk Maniac after his home city, he has evaded police for 12 years after officers questioned then released him due to “lack of evidence” at the time in what is now seen as a catastrophic blunder.

Later, police established “proof” of eight cases where women were raped and murdered by Andreev who – if he is still alive – would now be 68.

But he is also suspected of being responsible for abducting, raping and killing more than 100 women listed as “missing” between 2006 and 2016 in Orenburg region in southwest Russia, close to the border with Kazakhstan, according to law enforcement.

If true, this would make him Russia’s worst-ever serial killer, exceeding ex-policeman Mikhail Popkov, aka The Werewolf, who has been convicted of 81 murders in Siberia – and confessed to an additional two.

A decaying male body discovered near Akkermanovka is undergoing tests, reported Shot media outlet.

The man was wearing a T-shirt bearing the words ‘Collection of 99 International Games’ and dark trousers.

All his teeth were gold – matching wanted descriptions of the suspected mass killer.

The cause of death is as yet unclear.

There have been frequent “sightings” of Andreev after police offered a £15,000 reward for information.

His truck was tracked containing a stash of condoms, women’s underwear, and hair clips.

Among his suspected murder victims are Ekaterina Morozova, who was 19 when she disappeared in 2012.

Another is Irina Nikolskaya, aged 25 when she went missing  in 2012.

Two other suspected victims were named as Olga Zhuravleva and Arzhan Urkumbayeva.

Andreev has been on the run since 2013 when he was put on Russia’s federal wanted list.

He was described as a married father of two,  considered a “peaceful and obedient family man”.

Locals said he was “polite, well-mannered and respectable”.

He was a lorry driver for at least 15 years.

Earlier, police urged anyone seeing the suspected serial killer to contact them immediately.
