Sabrina Moss, a nursery nurse from Neasden, was gunned down as she celebrated her 24th birthday in August 2013.

The mother-of-one was killed when three gang members fired ‘indiscriminately’ into a crowd of people in Kilburn High Road.

Three killers, serving life behind bars for the murder of a nursery teacher,

Hassan Hussain, 31, of Cranhurst Road, Willesden Green; Martell Rico Warren, 24, of Napier Road, Kensal Green, and Yasin James, 21, of Chaplin Road, Wembley, were all found guilty of her murder at the Old Bailey in August 2014.

Today the trio challenged their convictions at London’s Criminal Appeal Court, with their lawyers arguing they were ‘unsafe’.

The court also rejected a bid by Warren and James to have their minimum sentences cut.

Lady Justice Hallett told the court the prosecution case was that Warren, Hussain and James were members of the Kensal Green Boys, or KGB, which had a longstanding feud with the South Kilburn Gang.

Lawyers for all three argued the jury should have been discharged after an unidentified witness was only revealed during the trial, and also said a detective’s evidence on gangs in the area should have been excluded.

But, dismissing their appeals, Lady Justice Hallett said the trial judge handled both issues appropriately and no ‘undue’ prejudice was caused.

Sitting with Mrs Justice Cox and Mr Justice Soole, she also said the evidence against the three was ‘strong’, adding: “Together, the various strands formed a compelling prosecution case.”

Rejecting Warren and James’ appeals against their minimum terms, she said that such long sentences were ‘reserved for the gravest crimes’ and that this was in that category.
