The family of a man who has died more than a decade after being shot in Shoreditch are pleading with anyone with information to come forward.

Police have launched a murder investigation following the death of Marvin Couson, who suffered serious brain damage in the incident 13 years ago outside the then-known Lime Bar in Curtain Road.

The 39-year-old has been confined to a hospital bed and unable to communicate or do anything for himself since the incident in May 2002.

Following his death on Saturday, August 8, a post-mortem examination at Croydon mortuary gave the cause of death as brain injury, which was sustained as a direct result of the shooting.

Marvin’s sisters Margaret and Deborah said in a statement this month: “It has been 13 years, two months, 27 days since Marvin was shot. He has been unable to walk or talk. Marvin’s suffering has now ended, but ours has only begun. We have visited him every single day and he was not alone when he passed away.

“We want people to look at the picture of Marvin suffering and realise that this is real. By staying silent and not helping police you have allowed the murderer to walk free. The person who pulled the trigger needs to be caught and we need justice for Marvin.”

Marvin was shot in the early hours of Saturday, May 12, outside the Lime in London Bar (known as the Lime Bar and now open as the Queen of Hoxton pub) after visiting the venue with his cousin.

But, the pair fled, along with a number of other people, after shots were fired inside the bar.

Marvin’s cousin then saw a red or burgundy Ford Fiesta, thought to contain at least two black men, driving fast along Curtain Road, which then struck him and he grappled with the front seat passenger.

A gun was then fired and the cousin walked back towards the bar to see Marvin lying shot on the ground.

Leading officer Detective Chief Inspector Noel McHugh said: “We know there are potential witnesses who did not speak to police at the time and I would ask them to now please come forward with any information, no matter how small. Do not assume that someone else will contact police.

“A lot changes in 13 years and maybe you knew something at the time but were too nervous to speak to us. Marvin and his family have been robbed of all the things we take for granted, he was at the Lime Bar simply for a night out with friends and this should not have happened. His family have endured 13 horrendous years and now they no longer have Marvin and they do not have the answers they deserve.

“I would ask those reluctant to speak to police to look at the picture of Marvin lying in his hospital bed and think of his mum and dad when pondering ‘do I make that call?’

“Maybe you have heard talk over the years about Marvin’s shooting - if you can help please contact us.”
