A nurse who met her new partner on a dating app not realising he was a convicted child rapist and murderer came home from work to find her two daughters knifed to death.
Vitaly Molchanov went on the run after the killings of Yana Saprunova and Elena Saprunova, aged 13 and eight and a major manhunt was launched.
One month ago divorcee Valentina Saprunova, 40, moved 1,600 miles with her daughters from her Siberian home to move into her new boyfriend’s flat, convinced she had found true love.
The nurse had met Molchanov online via a dating app around six months earlier.
But she was unaware of his past convictions for child rape and murder.
He had been released from prison in 2010 after serving a long sentence, say reports.
She took a job at a local hospital in Rybinsk, Yaroslavl region, but came home from work on Tuesday to find both girls “literally shredded” by a knife.
Her lover was seen fleeing from the scene on a white bicycle.
The Russian Investigative Committee has opened a criminal case into a double child murder “committed with extreme cruelty”.
REN TV stated: “Perhaps this tragedy would not have happened if Valentina, before going to live with this man with whom she had only talked on the Internet, knew an important thing: he had already served a sentence for the rape and murder of a child.
“But Vitaly hid it from her.”
Komsomolskaya Pravda newspaper reported: “Vitaly carefully concealed his criminal past from his girlfriend.
“Otherwise, this woman, knowing the crimes for which her lover was sentenced, would in all probability not agree to uproot from the Omsk region to Rybinsk and with her two children to move in with him.”
Sources said that Molchanov had become angered and “jealous” that her job involved 24 hour shifts from which she often came back late.
A neighbour said: “This woman came to look for happiness in Rybinsk.
“I feel so sorry for her and the girls. He is a beast.
“He must be destroyed immediately.”
The man’s neighbours also did not know about his earlier convictions.
A law enforcement video showed forensic specialists working at the flat where the girls were killed.
Forensic evidence established both dead girls had been raped before they were killed, said the Russian Investigative Committee in a statement.
The missing suspect will face two charges relating to sexual violence.
