Sheila Caffell

In December 2019 Bamber's lawyers made a further application for the disclosure of withheld evidence in relation to Bamber's phone call to the police on the night of the killings and a silencer.

In October 2019 he claimed that new evidence, of a telephone call he made, proved he did not murder his family. He believed that a police telephone record, showing that he was elsewhere at the time of the killings, had been unearthed.

Returning a majority verdict, the jury found that, after committing the murders to secure a large inheritance, Bamber had placed the rifle in the hands of his 28-year-old sister, who had been diagnosed with schizophrenia, to make the scene appear to be a murder–suicide. Bamber is serving life imprisonment without the possibility of parole. As of November 2016 he was one of 70 prisoners in the UK subject to a whole-life order, and is the only such prisoner to assert his innocence.

In January 2012 Bamber and two other British prisoners, Peter Moore and Douglas Vinter, lost a case before the European Court of Human Rights, in which they argued that whole-life imprisonment amounts to degrading and inhuman treatment. In July 2012 they were granted the right to appeal that decision. In July 2013 the Court's Grand Chamber ruled in their favour, holding that there must be a possibility of release and review.

Bamber launched two unsuccessful lawsuits while in prison to recover a share of his family's estate. His grandmother had cut Bamber out of her will when he was arrested, and most of the inheritance went to June Bamber's sister. In 2004 Bamber went to the High Court again to claim a share of the profits from the Bambers' caravan site in Maldon. He had retained his shares after his conviction, but had sold them to pay the legal costs arising from his claim on his grandmother's estate. The court ruled that he was not entitled to any profit from the site because of his conviction.

Bamber has repeatedly applied unsuccessfully to have his conviction overturned or his whole life tariff removed; his extended family remain convinced of his guilt. The Criminal Cases Review Commission (CCRC) referred the case to the Court of Appeal in 2001, which upheld the conviction in 2002. The Court of Appeal ordered full disclosure of evidence to the defence, but this did not take place. The appeal was rejected and the CCRC rejected further applications from Bamber in 2004 and 2012, having not identified any new evidence or legal argument capable of raising a real possibility that the court of appeal would quash the conviction.

In 2001 The Times alleged that he had been treated with indulgence at Long Lartin Prison, Worcestershire, where prisoners were given the key to their cells. Among the allegations were claims that he studied for his GCSE in sociology and media studies, had a daily badminton lesson, and drew pictures of supermodels in an art class, which he later sold through an outside agent.

A group of outside supporters has formed around Bamber, and he has reportedly developed several close relationships with women since his conviction. He defended himself on one occasion from a knife attack by another prisoner by using a broken bottle, and on another received 28 stitches on his neck when attacked while making a telephone call. In 1994 he called a radio station from Long Lartin prison to protest his innocence.

He was found guilty in October 1986 of the August 1985 shooting of his parents, his sister, and his sister's six-year-old twin sons at his parents' farmhouse in Essex.

Bamber alerted police to the shootings at around 3:30 am on 7 August 1985. He told them that Nevill telephoned him to say that Bamber's sister, Sheila Caffell, had gone "berserk" with Nevill's rifle. When police entered the farmhouse Caffell was found dead on the floor of her parents' bedroom, with the rifle up against her throat. June Bamber was found in the same room. Caffell's six-year-old twin sons, Nicholas and Daniel, were found in their beds in another upstairs room, while Nevill was found in the kitchen downstairs. The family had been shot 25 times, mostly at close range.

Bamber attended St Nicholas Primary, followed by Maldon Court, a private prep school, then from September 1970 Gresham's School, a boarding school in Norfolk. Claire Powell writes that Nevill felt it would be inappropriate to send the boy to a local school for the village children, when he might one day have to employ them on the farm. This led, writes Powell, to a situation in which Bamber felt increasingly alienated from his family and their life in the countryside, as did his sister, who was also sent to boarding school. He left school with no qualifications, much to Nevill's anger, but managed to pass seven O-levels at sixth-form college in Colchester, which he left in 1978.

Jeremy Nevill Bamber (born Jeremy Paul Marsham; 13 January 1961) is an Englishman who was convicted of the White House Farm murders.

The Bambers were wealthy farmers who lived in a large Georgian house at White House Farm, near Tolleshunt D'Arcy in Essex. Nevill was a local magistrate and former RAF pilot. In 1957, four years before adopting Jeremy, the couple had adopted a baby girl, Sheila.

Bamber was born Jeremy Paul Marsham at St Mary Abbot's Hospital, Kensington, London, to Juliet Dorothy Wheeler (born 1938 in Leicester), a vicar's daughter who had had an affair with army Sergeant Major Leslie Brian Marsham (born 1931 in Tendring, Essex), a controller at Buckingham Palace. She gave the baby up for adoption in 1961, the year of his birth, through the Church of England Children's Society. Nevill and June Bamber adopted him when he was six months old. It was only after Bamber's conviction that his biological parents were told by reporters that Bamber was their son. They were by then married to each other and working at Buckingham Palace.
