Son Killed His Mother 'After She Tries To Have Sex With Him

 A teenage oligarch's son told how he wanted to 'expel the devil' from his mother when he strangled her to death with the cable of a phone charger in a Russian hotel.

Egor Sosin, 19, claimed minutes after killing her that his mother had wanted to have sex with him, and he had refused, before he brutally attacked her, according to a new witness.

Gruesome new details have emerged over the murder of 44-year-old Anastasia Novikova-Sosina, ex-wife of construction mogul Igor Sosin, in a blood-strained hotel suite in the Volga River city of Kazan.

Sosin, who said on social media he was a student at the Hult International Business School in London, is reported to have told state investigators: 'I had been choking her about half an hour. Satisfied that she had died, I sat on her and began to punch her with all my force.

'I hit her in the face. There were not less than 20 hits, they were strong.

'I cried when I hit her, and I was well aware that with my actions I was killing my mother.

'I bit her into the neck on the right side and felt the blood in my mouth.

'I saw blood running from my mother's face from my hits.'

Now LifeNews - which has close links to law enforcement in Russia - has reported that the teenager gave his first explanation of why he killed his mother to staff from five star Korston Hotel when they entered the room where the mother and son were sharing in December.

Hotel manager A. Mananov told investigators: 'He said that the woman was his mother.

'According to him, she tried to persuade him to be intimate, and gave some pills. Sosin said that he refused to have sex, and then expelled the devil out of her.'

It has been reported that a 'preliminary finding' of paranoid schizophrenia was diagnosed after psychiatric examination of Sosin junior.

As yet there has been no official comment on his mental state.

If such a diagnosis was confirmed, and accepted by the court, he would not face trial for murder, or go to jail, because he was not responsible for his actions.

Instead he would be ordered to undergo treatment in a psychiatric hospital.

However, the court will have to examine testimony from the wealthy teenager which suggests he knew he was killing his mother.

In his first comments on the killing, tycoon Igor Sosin said he had been in close contact with his ex-wife over their concerns for their son.

The boy's mother had told him the teenager's behaviour was 'not quite sane' and that he was 'obsessed with delusions of persecution'.

He told investigators: 'I regularly called Egor, to be sure that he was sleeping at home.

'On one occasion, the way he spoke seemed to me messy, so I decided that he had some inadequate condition.

'And then I got a call from Anastasia. She said that Egor had had a party in their apartment and they used the laughing gas and 'mushrooms' there.  Daily Mail reports
