BBC Crimewatch fimed dying man's last moment (WATCH VIDEO)

The last breaths of a shooting victim were broadcast on TV last night as police announced a £40,000 appeal to catch his killer. 26 year-old Marvin Couson was gunned down in front of up to 300 people outside a bar in Shoreditch, East London, causing a brain injury that left him in a vegetative state. watch video after the cut.

Following the attack in 2002 Mr Couson spent the next 13 years ‘in pain, in suffering’ according to his family - before he died in August, just months from his 40th birthday.

The BBC's Crimewatch programme yesterday broadcast phone footage taken by his sister Margaret at his bedside in hospital just minutes before he passed away.

She told the show: ‘I feel people need to see that this man, this innocent man - completely innocent - suffered in this way until he took his last breaths because someone took a gun and shot him.’

Police were called to the Lime in London Bar, or Lime Bar, in Curtain Road at 3.40am on May 12, 2002 after reports gunshots had been fired. The bar is now the Queen of Hoxton pub. Mr Couson, a father-of-two from West Norwood, South London, was found lying on the ground with a bullet wound to his chest, police said. 

The Crimewatch reconstruction showed that a gun was fired in the bar and people fled outside.

A friend confronted two men driving past in a T-registration red or burgundy Ford Fiesta and as he did so a second shot was fired, hitting Mr Coulson.

He was taken to the Royal London Hospital with critical injuries to his heart and other internal organs before being transferred to the Royal Hospital for neuro-disability. 

He died in hospital on August 8 last year. A man was arrested on May 23, 2002 in connection with the shooting, but released with no further action.

Police said it was not clear if the shot came from inside the car but they want to trace the men inside. They said 200 to 300 of the 600 people at the bar for a party had fled into the street before the shooting happened.
