A man who was involved in a Birmingham gangland murder that sparked the Aston New Year shootings has been told he must serve out his life sentence.
Kieron Richards was just 16 when he was a participant in the 2002 killing of Yohanne Martin, a leading member of the city's notorious Burger Bar Boys.
The judge who originally passed sentence described the shooting as "a clinical and merciless execution" carried out on a street full of people by "perpetrators who believed themselves immune from being brought to justice".
The High Court in London has now refused a plea for a reduction in the 16-year sentence that Richards must serve before applying for parole.
Reviewing the case, Mr Justice Silber said Richards - described as a "junior partner" in the murder - had won plaudits from prison staff for his attitude during his ten years in prison.
However, the judge said his conduct in jail was not so "exceptional and unforeseen" as to justify a cut to his sentence.
Gang leader Yohanne Martin was blasted to death while sitting in his car in West Bromwich in December 2002.
He was hit by six bullets when a hail of semi-automatic gun fire came from a passing stolen vehicle, during a bitter three-year territorial feud, played out on the streets of Birmingham.
Richards, a member of the Johnson Crew, was a passenger in the vehicle and was said to have fired a number of shots at Martin.
The murder culminated in the deaths of innocent teenagers Letisha Shakespeare and Charlene Ellis.
The best friends were accidentally shot as gunmen targeted rivals in a revenge attack outside a late-night party in January 2003.
Charlene's twin sister Sophie, their cousin Cheryl Shaw and friend Leon Harris were also injured in the Aston shootings but survived.
Four men were later convicted of Letisha and Charlene's murder at a trial in Leicester, which saw evidence from anonymous witnesses for the first time.
