A CONVICTED killer has launched a High Court challenge for the disclosure of evidence which he believes will see his conviction overturned.

Jeremy Bamber was jailed in 1986 for the murders of his parents Nevill and June, his sister Sheila Caffell and her six-year-old twin sons, Nicholas and Daniel, at White House Farm in Tolleshunt D’Arcy. He has always protested his innocence.

Now lawyers working on his behalf have made an appeal to the High Court claiming the Crown Prosecution Service has failed to follow directions to disclose material showing two gun silencers were taken from the farm, not one.

Bamber contests evidence from the two silencers was also contaminated and presented to the jury at his trial as coming from one silencer.

He says Sheila, who had mental health problems, killed the family before turning the gun on herself.

Southend Standard:

The prosecution in the 1986 trial argued it could not have been Sheila because she could not have killed herself while the sound moderator was on the gun because her arms were simply too short to have reached the trigger.

The trial judge Justice Drake, in his summing up, told the jury: “On the evidence of the silencer alone you may find Mr Bamber guilty.”

But Bamber claims a letter sent from a forensic expert said blood found on the silencers, which was presented as definitely being from Sheila, was also a match for his late uncle Robert Boutflour. This was not disclosed to the defence, he says.

Southend Standard:

Speaking to the Gazette from Wakefield high security prison, where he is serving a whole life tariff, Bamber said: “Take away the silencer and there is nothing.

“I am excited, I believe this is the beginning of the end.

“The Crown will be forced to admit there were two silencers. They can’t continue with my conviction.”

He added: “There were two silencers taken from White House Farm and it was presented to the jury as though there was one. We are asking for the disclosure of evidence which proves there were two silencers taken.”

Bamber has had two appeals thrown out and a bid for a third turned down in 2012.

A dramatisation based on the murders is set to be screened on ITV next month.

A spokesman for Essex Police said: “Bamber’s conviction has been the subject of several appeals and reviews by the Criminal Cases Review Commission. There has never been anything to suggest that he was wrongly convicted.”
