Jailed Sheffield brothers speak out from prison after a decade behind bars for murder

David and Ashley Cohen, who are behind bars at HMP Whitemoor in Cambridgeshire, were jailed in April 2008 after being found guilty of killing 53-year-old cab driver, Younis Khan, but have always denied responsibility.

They claim a confession by prosecution witness Vincent Simmons that he lied during their trial casts a new light on the case against them and should merit an appeal or re-trial.

He called the Cohen family and in recorded telephone conversations admitted that it was 'beneficial' for him to give evidence against the brothers during their trial because he never went to prison for offences he was facing jail for.

The recordings were examined by the Criminal Cases Review Commission but the case was not referred to the Court of Appeal.

By making the existence of the recordings public, the Cohen brothers hope their case will be looked at again.

David, a dad-of-two whose 20-year-old son is studying criminology at university in a bid to take on the case, said he and Ashley had always maintained that Simmons was lying but had been unable to prove it until now.

"I feel let down by the criminal justice system," he said.

"All I want is a fair trial. I want a trial where the evidence used against me is not the cell confession evidence that is false. What I want is a re-trial or a fair day at the Court of Appeal, where they can assess what has happened. I believe the Court of Appeal will do the right thing."

Recalling the last decade spent behind bars, he said: "I have only got one life to live. I believe what has taken place is outrageous."

He admitted to having a criminal history from his younger days but stressed that he was not a killer.

"I'm not going to pretend I was as good as gold, I wasn't an angel but I'm not a killer," he said.

"They have me, my brother and our little brother all serving life and (we've) not killed anyone.

"I'm not going to lie, I'm not pretending to be anything that I'm not but I'm not a murderer."

David, 38, from Upperthorpe, said that because he has never admitted murder or shown remorse while behind bars he may never be released unless his conviction is quashed.
