A man has pleaded guilty to murdering a 15-year-old girl whose dismembered body was found dumped on a housing estate.
Rochelle had gone to make a phone call
John McGrady, 48, of Milford Towers, Catford, south London, carried out the attack on Rochelle Holness last September, the Old Bailey heard.
She vanished after going out to call her boyfriend from a phone box near her home in Lewisham, south London.
Her body was found in bin bags near a stairwell on the Milford Towers estate. McGrady will be sentenced on 15 May.
Her attacker was said to be a heavy-drinking handyman with previous convictions for rape and false imprisonment.
The 48-year-old was remanded in custody at the Old Bailey and warned he would receive a life sentence at the next hearing.
Detective Inspector Tim Grattan-Kane said: "John McGrady is an absolute danger to any young woman, a spectacularly dangerous and violent man who when a desire befalls him he decides to inflicted it on innocent victims.
'He is prepared to use outrageous violence to achieve his ends."
Anthony Orchard, prosecuting, said the court would require a psychiatric report before sentencing.
Rochelle is thought to have been snatched at knifepoint from the phone box on a Sunday evening before being strangled and dismembered.
Her remains, placed in five bin bags and dumped in a supermarket trolley, were found by ambulance staff who had been called to the estate on 28 September 2005.
Rochelle had been missing for three days when McGrady cut his wrists and confessed to his girlfriend.
He was arrested after receiving treatment for minor cuts.
Rochelle's father Denroy stumbled across the murder scene while out searching for his daughter with other family members.
History of abductions
Mr Grattan-Kane said McGrady had a history of abducting women in the street and forcing them to do things at knifepoint.
In 1998, he was jailed for six years for raping and sexually assaulting two women he knew.
Five years earlier he had been in prison for five years for false imprisonment of a young woman he abducted at knifepoint as she came off a bus.
Mr Grattan-Kane said: "I am fairly confident Rochelle was dead within an hour of going into his flat."
He said Rochelle's family had been devastated.
"It is a nightmare no parents should have to face. She was her mum and dad's pride and joy and she was loved to bits by her brothers."
