The portrayal of the Welsh detective at the heart of ITV's dramatisation of the murders at White House Farm has been controversial since the drama first aired last month.
Detective Chief Inspector Thomas 'Taff' Jones was the man leading the investigation into the horrific events that took place in August, 1985.
But, he has also been blamed for making errors in the probe into the deaths of Nevill Bamber, his wife, June, daughter, Sheila, and her two children, Daniel and Nicholas.
As the drama shows, the detective accepted without question that Sheila Bamber had opened fire on her own family before turning the gun on herself in a gruesome murder/suicide - despite fellow officers offering suggestions to the contrary.
The Mirror reports that his actions meant the home was no longer deemed a crime scene just hours after the deaths, and vital evidence was possibly missed.
It soon became apparent that Jeremy Bamber had murdered his entire family and then tried to pin the blame on his mentally ill sister Sheila.
After shooting his father dead in the kitchen, he killed his mother in his parents' bedroom before shooting his two young nephews as they slept in bed.
He then shot his sister dead and placed the gun next to her body to make it look as though she was the one responsible.
He then returned home and called police himself to tell them his father had phoned and told his Sheila was "going beserk" with a gun.
Within hours of the killings, Detective Taff Jones was convinced Sheila was the one responsible - backed up by the police surgeon who examined the bodies before the senior officer arrived at the crime scene.
In the weeks following the deaths of his entire family, it appeared that Jeremy Bamber was a grieving son - but to those close to him, not everybody was convinced.
Several of the other officers investigating what had happened at White House Farm felt something was amiss with the then 24-year-old.
Detective Sergeant Stan Jones was one of the first to suspect Bamber's story may not be the truth and voiced his concerns to his superior officers.
He said: "We're not happy with this bloke, his demeanour, his answers to out questions, this ain't a bloke grieving.
"This is an oddball, a guy who is not all he seems."
Nevertheless, his concerns were not taken seriously by Essex police.
It was only a month after the murders when Bamber's girlfriend Julie Mugford came forward was Jeremy implicate in the murders.
He was arrested, charged and the following year tried of convicted of all five murders.
Jeremy Bamber will spend the rest of his life behind bars, but in a tragic twist of fate Taff Jones was never able to see him convicted.
Just before the trail began, the man who originally lead the investigation died in a freak accident at his home.
While little is known about the exact circumstances of the death, it has been reported that he fell off a ladder.
Since the drama aired, several officers from Essex Police have criticised the portrayal of Jones in White House Farm.
Det Cons Michael Clarke told The Sun: "They are making him a scapegoat.
"It wasn't until we started pulling in the evidence provided by Bamber's girlfriend and finding things wrong with Jeremy's story that things started to change.
"And Taff's mind was definitely changed."
What happened to Jeremy Bamber?
After a statement about Bamber's hatred of his family by girlfriend Julie Mugford and his alleged plans to kill his family to inherit their fortune, he was arrested a month after the murders, on September 8, 1985.
His trial in October 1986 saw him found guilty by a majority of 10 to two. He was sentenced to five life terms and the was told by the home Secretary in 1994, Michael Howard, that he would remain in prison for the rest of his life.
Bamber has lodged appeals several times, against his conviction and against his whole-life tariff . He still maintains his innocence.
