THE distraught Chester mother of a brutally murdered teenage girl says the man who killed her daughter should never have been 'allowed to wander the streets at night'.

Mark Corner killed former Saltney schoolgirl Hanane Sarah Parry, 19, and Liverpool prostitute Pauline Stephen, 25, before dismembering and dumping their bodies.

And yesterday, Hanane's mother Diane Parry, of Warren Drive in Broughton, demanded to know why schizophrenic Corner had not been kept locked up in a secure hospital as he was once a patient of Mersey Care NHS Trust.

The 42-year-old said: 'Hanane has got a little sister who has been left devastated by what that man did. He is sick and should not have been allowed to wander around the streets at night.

'I will never get Hanane back but her death should show the Government how big mistakes are being made.'

Liverpool Crown Court heard that 26-year-old Corner was arrested after he confided in his brother who went to the police when body parts were discovered near to Corner's home.

Sending Corner to a high security mental hospital indefinitely, Mr Justice Gage said: 'These were truly horrendous crimes. The details are gruesome in the extreme and have no doubt have caused immense distress to relatives and friends of these young women.

'The offences occurred on consecutive days in July. Each day you took a prostitute back to your flat, after engaging in sexual activity with your victims you then killed them.'

Corner had denied murdering 19-year-old Hanane Parry and Pauline Stephen, 25, but pleaded guilty to manslaughter on the grounds of diminished responsibility.

David Steer QC, prosecuting, said that Miss Parry was working as a prostitute in the Netherfield Road and Walton Road areas of Liverpool at the time of her death.

She went out working at 2pm on Friday, July 11 and failed to return but police were not notified of her disappearance at that stage.

The following day Miss Stephen, of Skelmersdale, left home about 11pm to go out working. She too failed to return home and the police were informed on July 14.

Four days later her white Ford Escort was found abandoned in St Domingo Vale.

Merseyside Police found human remains in plastic bin bags in an alley behind Corner's first floor flat in St Domingo Vale, Everton, on Sunday, July 20, but they were unaware they involved two bodies.

But when Ian Corner went to Crosby Police Station the next morning he told them his brother had confessed to killing two women and dismembering them.

Corner's flat was searched and what appeared to be blood was found on the bathroom sink and bath.

Mr Steer said Ian Corner told police his brother said he had panicked while disposing of the bodies and left some of them in Stanley Park near Liverpool football ground.

The park was evacuated, sealed off and searched and the missing parts were found with the assistance of a specially trained police dog.

Fingerprinting led to the positive identification of Hanane Parry.

Later the same day Ian Corner again contacted police and told them that his brother had arrived at their parent's Kirkdale home and police went and arrested him.

David Aubrey, QC, defending, said that Corner, who only has one previous conviction for being drunk and disorderly, had been known to psychiatric agencies since the age of 17.

At the time of the offences 'he was suffering an abnormality of mind which was untreated schizophrenia symptomised by auditory hallucinations, delusions of persecution and violent and sadistic thoughts. It substantially impaired his mental responsibility at the time and he remains a grave danger to the public.'

At the time of her death, the Brougton community, where Miss Parry grew up was left stunned.

Hanane had attended Broughton Junior School and then moved on to St David's High School in Saltney before leaving in 2000.

Her mother Diane paid tribute to her: 'Hanane was extremely kind-hearted and her name actually means 'kindness'.

'She was a generous girl and close to her brother and sister, who are unbelievably shocked by her death. She was a beautiful girl at the start of her life and had a shy unassuming nature.

'I would describe her as a free spirit who was head-strong and liked her own company and all of her friends at home will miss her a great deal.'

Mrs Parry said that Hanane was a 'wonderful girl' who had been led down the wrong path in life.

She gave an example of her daughter's generosity: 'When she was 17, I bought her a new pair of trainers. But she gave them to a homeless man and said he needed them more than she did.'
