The jury is out on the trial of three men accused of gunning down a mother as she celebrated her 24th birthday in Kilburn.

Sabrina Moss, from Neasden, died after she was shot dead in Kilburn High Road, in the early hours of August 24 last year.

Her friend Sabrina Gachette, 24, and two men Mahad Ahmed, 23, and Edson Da Silva, 27, were also injured when Ms Moss’ killers open fire with a MAC-10 submachine gun and a sawn-off shotgun outside Woody’s Grill.

The Old Bailey heard claims Martell Warren, 22, of Napier Road, Kensal Green, Hassan Hussain, 29, of Cranhurst Road, Willesden Green, and Yassin James, 19, of Chaplain Road, Wembley, carried out the shootings.

Prosecutor Mark Heywood QC told jurors the shootings were the tragic result of an ongoing violent dispute between the alleged killers and a group from South Kilburn.

The accused killers are claimed to be members of Kensal Green Boys (KGB) and Ahmed and Da Silva are said to have associations with the ‘South Kilburn Gang’ also known as Family About Cash (FAC) or the Money Making Family (MMF), jurors were told.

Det Supt Simon Rose, second in command at Brent Police, told the court that there were 13 known gangs with 264 known members in Brent as of October last year.

He added: “The vast majority of all gangs in Brent are very tightly postcode specific. Each gang would have its own patch such as an estate.

“They would be involved in dealing drugs, violence, retaliatory attacks on other gangs and acquisitive crime such as robbery and burglary.”

Giving evidence, Miss Gachette wept as she described hearing a loud explosion.

“I opened my eyes and in front of me was Sabrina,” she added.

“Then she said: ‘I’ve been shot in my heart’.’’

Warren admitted driving the gunmen to the scene but insisted he knew nothing about the shooting.

A former Hilton hotel chef, he has a string of previous convictions stretching back to 2006 when he was aged 15, including criminal damage, possession of a firearm and drugs offences.

He claims he knew Hussain and James through drug dealing and said ‘it was always business’ when they met each other but denied being a member of any gang.

James’ own lawyer James Scobie QC admitted the teen was a ‘low life drug dealer’ but said that does not make him a killer.

He told jurors: “A toe rag Class A drug dealer is a mile apart from a cold-blooded killer who pulled the trigger at point blank range.”

Mr Scobie accused Warren of lying to the jury and said he had a ‘love-in’ with the prosecutors as he tried to shift the blame.

A fourth man, Simon Baptiste, 29, of Rondu Road, Cricklewood, is accused of letting the alleged gunmen use his house as a base for the killing.

Warren, Hussain and James deny murder, three counts of attempted murder, two counts of possessing a firearm with intent to endanger life and two counts of conspiracy to cause grievous bodily harm.

Baptiste denies conspiring to cause grievous bodily harm.

Miss Moss, the mother of a four-year-old boy, worked as a nursery teacher in Alice Wonderland nursery in Stonebridge, had been celebrating her birthday with friends at Love and Liquor club in Kilburn High Road, shortly before she died.
