THE cousin of mass murderer Jeremy Bamber says the convicted killer is “guilty as hell”.

David Boutflour has spoken out after Bamber lodged another appeal to be set free.

Bamber was convicted of murdering five members of his family in their home at White House Farm, Tolleshunt D’Arcy, 24 years ago.

But his legal team has presented fresh evidence to the Criminal Cases Review Commission.

They claim scratch marks, evidence of a struggle between Bamber and his adoptive father Nevill, were caused five weeks after the shootings.

Mr Boutflour, from Wix, who is Nevill’s nephew, said: “There is no possibility he wasn’t guilty.

“Who could possibly murder two small children in their beds and their mother, father and sister?

“The case is closed as far as I am concerned and I am finding it very distressing.

“How can this guy keep coming forward with this? I wish the press would not give him any more credibility, because he is not worth it. Without a shadow of a doubt, this guy is guilty as hell. He wants to get out on a technicality.”

Mr Boutflour, 62, said during the trial the judge said three separate pieces of evidence put Bamber in the frame, each in their own right.

He added: “It does worry me that judgments of people in high places afford people appeals. There should be something strong in the evidence before they are allowed to appeal.”

Bamber killed his adoptive parents June and Nevill, sister Sheila Caffell and her six-year-old twins, Daniel and Nicholas.

During his trial, prosecutors said scratch marks in the farmhouse kitchen were evidence of a struggle between Bamber and his adoptive father.

Now, a top photographic expert believes the negatives of photographs taken by police show the marks were caused 34 days after the shootings.

Peter Sutherst says photographs taken on the day of the murder show no scratch marks.

The new claims are being looked into by the Criminal Cases Review Commission, which investigates possible miscarriages of justice.

Bamber, now 49, has always maintained his innocence, claiming his sister, a paranoid schizophrenic, killed her family before turning the gun on herself.

He was sentenced to serve a minimum of 25 years, but placed on a list of criminals who should never be released.
