A man has been jailed for life for strangling a teenager to death, more than a decade after her boyfriend was wrongly convicted of the murder.
Shahidul Ahmed killed and "brutally battered" 19-year-old shop assistant Rachel Manning in December 2000, dumping her body in undergrowth at a golf course.
Ahmed, 41, had hit Miss Manning repeatedly with a steering lock after she was dead, causing broken bones and disfiguring her face, Luton Crown Court heard.
ITV News correspondent Juliet Bremner reports:
Her boyfriend Barri White was jailed for the murder in 2002, but was later acquitted at a retrial in 2008.
Ahmed was put on trial after DNA evidence linking him to Miss Manning's death was discovered following his arrest for a sexual assault in 2010.
Sentencing Ahmed to life in prison with a minimum term of 17 years, Mr Justice Wilkie said:
For almost 10 years you lived undetected with the knowledge of what you had done.
You took out your anger and frustration on her much-loved face and disfigured it by great violence, having sought to dispose of her where she would not be found for a sufficient time to enable you to cover your tracks.
Mr White said he was "over the moon that justice has finally been done" and that he was "really happy that Rachel's family have finally got justice and the closure they deserve."
Following today's hearing Miss Manning's mother, Liz, said she believed her daughter would still be alive if she had not been "abandoned" by her boyfriend on the night she was killed.
Reading a prepared statement, she continued: "We believe Rachel would still be with us today if she had not been abandoned by her boyfriend the night she was attacked, killed and brutally battered. We cannot forget that."
Detective Chief Superintendent Rob Mason of Thames Valley Police said he had apologised to Mr White for his wrongful conviction.
