A mum was shot dead in front of her daughter as she sheltered behind her front door, a court heard.

Lianne Gordon, 42, was the unintended victim of a dispute between two gangs when she was killed in her home on Vine Close, Hackney. 

A 17-year-old, who cannot be named for legal reasons, is charged with murdering her and attempting to murder a 17-year-old and a 21-year-old during the same incident.

The shooting was alleged to be the culmination of a series of incidents involving the teenage murder defendant and fellow defendant Elijah Seriki, 21.

Opening their trial on Thursday, Mark Fenhalls KC said: “Lianne Gordon was sheltering behind her front door at home when (the youth) shot and killed her on December 5 last year.

“She was almost certainly not the target. But her tragic death was the culmination of an escalating dispute between two gangs. That dispute involved both (the youth) and Elijah Seriki.”

The prosecutor said Ms Gordon had lived in Vine Close with her 16-year-old daughter and 21-year-old son Kaymound, who has cerebral palsy and uses a wheelchair.

At the time of the shooting, Kaymound had been taking a shower. His sister emerged from her room to find her mother slumped on the floor and was with her when she died, Mr Fenhalls said.

The prosecutor told jurors they would be struck by the “obvious devastation” of Ms Gordon’s children and wider family but told them they must put any feelings to one side.

He added: “The Gordon family were not the only target – they were abroad on holiday in Jamaica on December 2, only returning on morning of the December 5.”

Mr Fenhalls said the shooting had resulted from a dispute between two Hackney gangs – the Pembury Gang, with which the defendants were associated, and the A-Road Gang, with whom Ms Gordon’s son Kaymound was linked.

Jurors were told Kaymound had denied membership of the A-Road Gang but said problems began in 2019 when his friend Dotz was murdered.

Over the years each side would disrespect each other in music and on social media and there were revenge attacks, jurors were told.

Kaymound had admitted that he punched Seriki in a shop because he thought he was about to draw a knife, jurors heard.

It is also alleged the two threatened Kaymound with a large knife as he smoked a cigarette on his doorstep on October 1 last year.

The defendants are charged with affray, having a firearm with intent to endanger life and possession of a bladed article during an alleged 'ride out' from their gang's territory the following day.

On the incident on October 1 last year, he said the defendants “literally tried to stab us” on his doorstep with a large black blade.

The teenage defendant had travelled back to Hackney even though his family had moved away in June 2022 to try to distance him from the gang, the court heard.

He had a series of previous convictions dating back to when he was 15.

Among them was a conviction for attempted murder relating to an incident at Hackney Central station on March 1 last year.

Mr Fenhalls said the defendant had been involved in planning and passing on information, but not personally involved in the violence.

Seriki, from Hackney, also had previous convictions from the age of 15 relating to drugs and weapons, including a zombie knife, the court was told.

Both defendants deny the charges against them. The Old Bailey trial continues.
