He was convicted of raping, beating and then killing Albina Ganzei after offering to drive her to school.

Instead he took her on a remote road and viciously attacked her.

Then he burned her body.

Her charred remains were found in long grass four days after Albina's mother reported her missing.

She was still wearing her favourite pink shoes.

Police found at least three other girls he raped and violently sexually attacked.

He committed the attacks in 2015 prompting a mass search in the Primorsky region of western Russia.

The following year he returned to a crime scene and police caught him after being alerted by locals.

'His cell phone and computer contained "numerous" images and videos showing "vile" child pornography,' The Siberian Times reported.

After his arrest, he confessed to police and revealed details of his crimes.

No further details have been given about the woman and man accomplice who were involved in several sexual attacks.

They were jailed to three-and-a-half and four years respectively.
