The family of murdered teenager Rachel Manning said she would still be with them today "if she had not been abandoned by her boyfriend the night she was attacked, killed and brutally battered."
"We cannot forget that," they added.
The former boyfriend of Rachel Manning has said that he would not be a free man now if a television documentary had not raised questions over his murder conviction.
Barri White was convicted of her murder in 2002, but five years later this was quashed by appeal judges and he was acquitted in 2008 after a re-trial.
The retrial came after the case was featured on a BBC Rough Justice documentary which raised questions about key scientific evidence in the first trial.
Following the sentencing of Shahidul Ahmed, the Chief Crown Prosecutor for Thames and Chiltern Crown Prosecution Service (CPS) said he was an "extremely dangerous" man who already had convictions for sexual assault.
Shahidul Ahmed, 41, was put on trial after DNA evidence linking him to Rachel Manning's death was discovered following his arrest for an unrelated matter in 2010.
He hit Miss Manning repeatedly with a steering lock after she was dead, causing broken bones, Luton Crown Court heard.
DNA found on the steering lock matched Bangladesh-born Ahmed after it was discovered by the road on the direct route between the spot where the body was hidden and Shahidul Ahmed's home.
Shahidul Ahmed has been convicted of strangling a teenager whose boyfriend was wrongly jailed for the murder.
Ahmed killed shop assistant Rachel Manning, 19, in December 2000, dumping her body in undergrowth at a golf course.
Her boyfriend Barri White was convicted of the murder in 2002 but later acquitted at a retrial in 2008.
Barri White, who was wrongly jailed for Rachel Manning's murder, said that he was "over the moon" that Shahidul Ahmed had been convicted of her murder.
He added adding 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".
Shahidul Ahmed, 41, was given a life sentence with a minimum term of 17 years at Luton Crown Court for the murder of 19-year-old Rachel Manning, whose boyfriend Barri White was wrongly convicted of the killing.
