Jeremy Bamber receives a boost in his 40-year-bid for freedom as whistleblower says police DID tamper with the murder scene to frame him for killings

Jeremy Bambers 40-year bid to prove he is innocent of the White House Farm murders has received a significant boost after bombshell claims by a police whistleblower that officers tampered with the crime scene to place Bamber in the frame for the killings.

The retired Essex Police CID officer has broken ranks after reading Bambers submissions to the Criminal Cases Review Commission (CCRC), which is deciding whether to refer the case to the Court of Appeal.

Bamber is serving a whole-life tariff for the murders of his adoptive parents Nevill and June Bamber, both 61, his adoptive sister Sheila Caffell, 28, and her six-year-old twins Daniel and Nicholas. They were all shot at the Essex farmhouse on August 7, 1985.

The 64-year-old has always insisted that Sheila, a paranoid schizophrenic, carried out the murders before shooting herself.

He received a boost last year after an article in the New Yorker magazine highlighted more than a dozen apparent discrepancies in the prosecutions case.

The submissions, which are under review by the CCRC, include evidence from one of the worlds leading ballistics experts who says the jury may have been misled because Essex Police changed the evidence by moving Nevill Bambers body before the crime scene photos were taken.

In his detailed written statement, the whistleblower corroborates the claim that Essex Police changed the evidence, claiming that officers disturbed the murder scene at White House Farm hours after the shootings, with items removed and replaced before the photos were taken.

At Bambers trial in 1986 the prosecution showed the photos to the jury, without any mention that police had disturbed the kitchen or the bedrooms where the bodies were found. The photos helped secure a 10-2 majority verdict.

The murders occurred at White House Farm in Essex on August 7, 1985, but a whistleblower has now claimed Essex Police took video footage of the murder scene which was later destroyed

The whistleblower claims Essex Police took video footage of the murder scene, which was withheld from the jury and Bambers defence team and later destroyed.

Astonishingly, the whistleblower – who worked for the Essex force for 20 years and left with an exemplary record – says he was shown the footage by a very senior officer on the condition that it never became public.

The whistleblowers evidence is backed by two alleged Essex Police documents, which appear to confirm that footage of the crime scene did exist.

One document, apparently written in February 1991 and titled Bamber – Enquiry Exhibits (Location of), lists ten pieces of evidence from the case that went missing after the trial.

The list includes four reference numbers for video cassettes of scene. Essex Police denies any video footage existed.

The former CID officer – who has decided to remain anonymous for fear of reprisals – told The Mail on Sunday: You can restage a crime scene to make anybody look like the guilty party. In the White House Farm case, the crime scene constitutes the vast majority of the case against Jeremy Bamber.

If the crime scene has no integrity, then neither does the investigation, and it follows that neither does the case against Mr Bamber.

He has basically been convicted on a fabricated crime scene and a series of lies.

Essex Police said it stood by its investigation.
