Jeremy Bamber is the only British prisoner serving a whole-life order to have maintained his innocence, after being convicted of the murders of five people back in 1985.
The multiple murderer is still behind bars for the slaughter, which took place at White House Farm in Essex on the night of August 6.
Five people were murdered that night: Jeremy’s adopted farmer parents Nevill and June Bamber, their adoptive daughter Sheila Caffell and her six-year-old twin sons, Daniel and Nicholas.
Now, ITV has commissioned a six-part drama starting tonight that will shine a new light on to the case that gripped Britain for more than 30 years.
Here’s what Bamber’s victims looked like in real life, and the actors who will portray them in White House Farm.
Nevill and June Bamber
Wealthy farmers June and Nevill Bamber adopted Jeremy as a six-month baby after he was given up by his biological mother Juliet Wheeler, who was unmarried.
The couple – Nevill also worked as a local magistrate and former RAF pilot – lived in a beautiful mansion on the grounds of their farm near Tolleshunt D’Arcy, and had adopted baby Sheila four years before Jeremy arrived.
The Bambers gave Jeremy all the advantages of their privileged background, sending him to a private prep school then a boarding school in Norfolk, citing their concerns that he would find it difficult to employ the local village children on the farm when he grow old enough to take on the estate by himself.
But their son fell into a life of petty crime after leaving school with no qualifications, and staged a jewellery shop robbery on a trip to New Zealand financed by his dad.
Jeremy also robbed the family’s Osea Road Caravan Park some weeks before the farmhouse murders, and was only caught when his girlfriend Julie Mugford testified against him.
Nicholas Farrell will play Nevill in the ITV drama, while Amanda Burton will take on the role of June.
Nevill and June’s adoptive daughter Sheila suffered with paranoid schizophrenia and had been treated in a psychiatric hospital months before the murders.
With a successful career as a model, Sheila’s downward spiral was documented in the press after her brother Jeremy framed her for the horrific family decimation.
Sheila’s marriage to husband Colin had broken down and she turned to drugs and sex with older men to cope as her children lived with their grandparents.
Jeremy first moved to implicate Sheila when he rang the police at 3.30am on August 7, telling them his father had called him to say Sheila had gone “berserk” with a rifle.
He told cops the line had gone dead and met them at the farmhouse where they were greeted with the grisly sight of five bodies placed around the property and blood everywhere.
All five of his relatives had been shot at close range, with 25 shots fired into them.
Nevill was found in the kitchen with eight bullet wounds and head injuries, while the twins were found dead in their beds.
On the upstairs landing, June was discovered shot between the eyes, and lastly Sheila was found in the bedroom with two bullet wounds to her throat.
The rifle had been left over her body, so officers initially suspected she had gone on a rampage and shot down her family.
However, over the course of the investigation, small clues were uncovered that eventually led cops to suspect Jeremy – and he was arrested a few weeks later.
Sheila will be played by Cressida Bonas.
Daniel and Nicolas Caffell
The twin boys were staying with their mum Sheila and grandparents in the Essex farmhouse at the time of the murders.
They had told their dad Colin Caffell, who was estranged from Sheila, that they were nervous about staying with the overtly religious Bambers before Colin dropped them off there.
Colin later wrote in his book In Search Of The Rainbow’s End that he initially suspected Sheila had committed the slaughters.
But when Jeremy was arrested he changed his mind – and became certain his brother-in-law was the killer as a series of inexplicable clues came to light.
One was the fact Sheila’s body had two bullet wounds to the neck, suggesting she couldn’t have shot herself in a murder-suicide, as Jeremy had posited.
Secondly, Sheila’s feet were clean of blood – meaning she couldn’t have rampaged through the house killing her family.
A silencer fitted to the end of Nevill’s rifle had also been taken off and put in a cupboard after the weapon had been used multiple times – it was found three days after the murders by one of Bamber’s cousins.
But the most crucial piece of evidence that helped secure Jeremy’s conviction was the witness testimony from Julie Mugford, who split from Jeremy shortly after the family’s funeral.
She told police he had rung her on the night of the slaughters to say “it’s tonight or never” and had bragged about wanting to kill his family for 18 months.
Bamber was arrested on September 8 1985 and convicted in October the following year.
He is behind bars at HM Prison Wakefield in Yorkshire and is one of 70 high-profile criminals in the UK to be subject to a whole-life order, meaning he is likely to die in jail.
