LAWYERS for a convicted murderer say they have unearthed fresh evidence which undermines his conviction.

Jeremy Bamber was jailed in 1986 after being found guilty of the murders of his parents Nevill and June Bamber, his sister Sheila Caffell and her six-year-old twin sons Daniel and Nicholas in Tolleshunt D’Arcy.

Bamber is currently serving his whole life sentence at the high security Wakefield Prison, and has always protested his innocence.

He claims it was Sheila, who had a history of schizophrenia, who was responsible for the tragedy.

Lawyers for Bamber say they have found archived statements by senior officers and a police surgeon which contradicts the claim Sheila could not have taken her own life because there were two bullet wounds to her neck.

Quality Solicitors Jordan say the documents were never seen by the jury and suggest Sheila had just one wound at the time police entered the property.

They do not dispute she had two wounds by the time crime scene photographers arrived but say the failure to tell the jury of the discrepancy was wrong and do not know how she got the second wound.

The case is the subject of an ITV drama series called White House Farm which concluded last night.

Bamber’s team had asked for the programme to be delayed because they believed it would harm the process of a judicial review they had called for asking for the Crown Prosecution Service to disclose documents.

An Essex Police spokesman said nothing had ever suggested Bamber was wrongly convicted despite a series of appeals and reviews over many years.
