Man who beheaded his teenage girlfriend with a kitchen knife while she was still alive is jailed for life.

A man who beheaded his teenage girlfriend with a kitchen knife before stabbing himself has been jailed for life.

Aras Hussein, 21, attacked Reema Ramzan, 18, with the blade while she was still alive before plunging it into his own chest in his flat in Sheffield. 

Sentencing him to life, with a minimum of 20 years in jail, Justice Laura Cox said his motive for the attack was 'unclear and may never be known'.

After the attack, he was seen on the street by a neighbour, naked, holding a wad of money and a passport, and covered in blood.

The body of Miss Ramzan, left, was found in the kitchen of Iraqi-born Hussein's, right, flat.

The killer admitted manslaughter on the grounds of diminished responsibility but denied murder. However, he was found guilty of murder.

The body of Miss Ramzan was found in the kitchen of Iraqi-born Hussein's flat on June 4 last year. 

Mrs Justice Cox said Hussein had used 'severe and sustained' force to decapitate Reema in a 'chilling and brutal' attack.

She said: 'The pathological evidence indicated that she was likely to be alive while decapitation was taking place although at some stage, mercifully, she would have lost consciousness.

'The pain, terror, anguish and desperation she would therefore have suffered, as you inflicted these appalling injuries upon her and ended her life, is truly horrifying to contemplate.

'Why you did this to a young woman who was your girlfriend is unclear and may never be known.'

The court previously heard that Miss Ramzan had arrived at Hussein’s flat in Sheffield at approximately 2.30pm and had brought with her around £5,000 in cash, as well as her passport and a substantial amount of Iraqi currency.

After the attack, Hussein took off his clothes, stabbed himself and wandered into the street. The court how he approached a member of the public - who was waiting for a friend near Hussein’s block of flats - and asked him to take him to hospital.

The man refused, but alerted emergency services who arrived minutes later. The court heard that when the defendant got back to the flat he also called the police and was still naked when they arrived.

Prosecutor Graham Reeds QC said a neighbour of Hussein's heard a woman 'screaming for dear life' that afternoon, and that the defendant told emergency workers who came to his aid: 'I don't know why I did it.'
