The brutal slaying of Jeremy Bamber's family in their farmhouse in Essex has rocked the nation for over 25 years. Convicted of killing his parents, sister and her twin boys in 1985, Bamber has continually protested his innocence ever since. Now for the first time, we investigate vital evidence brought to light by his legal team, which could cast doubt on Bamber's original conviction. Is the right person behind bars? In the dead of night on the 7th August 1985, five members of the same family were brutally shot and murdered in the sleepy village of Tolleshunt D'Arcy. Police originally concluded that the sister, Sheila Caffell, had killed her family before turning the gun on herself. But a sensational turn of events shifted the focus to the only surviving immediate relative, Jeremy Bamber. After a short investigation, Essex Police arrested the young farmer and charged him with the five murders. In 1986 he was sentenced to life imprisonment with a minimum of 25 years behind bars. In this exclusive programme this dramatic case is told through the account of an officer investigating the murders along with a journalist, photographic expert, solicitor and MP.

A stunned nation was gripped by the horrific road-rage murder of 21 year old, Stephen Cameron, as it made headline news in 1996. On the 19th May, an apparent road rage confrontation on a busy road just off the M25 motorway resulted in Stephen Cameron being stabbed to death by Kenneth Noye. This senseless killing of a young man in broad daylight was witnessed by many passersby, but only Stephen's fiance helped bring the killer to justice in one of the biggest investigations Kent Police have ever faced. This is the tragic story of the murder of Stephen Cameron told from the inside through the accounts of his mother and father, Toni and Ken Cameron, and the Detective Superintendent tasked with tracking down the murderer.

Rachel Nickell was innocently walking her dog on Wimbledon Common back in 1992 when she became the victim of a vicious sexual assault and was stabbed forty times, with her attacker fleeing the scene. Along with her dog, Rachel's two year old son Alex was also present. A passer-by found Rachel's body, with Alex clinging to her side, repeatedly saying "wake up mummy, wake up". A huge police investigation ensued, and although the police didn't have many clues as to who carried out the fatal attack, they pinned their leads on to one man, Colin Stagg. They began ‘Operation Edzell', what was later described as a ‘honey-trap', which involved an undercover female officer, "Lizzie James", feigning a five month relationship (involving meeting together, phone conversation and letters) to try and coax the ‘truth' out of him. Believing they had enough evidence to send him to trial in 1994, the judge at the Old Bailey threw it out, believing it to be "deceptive conduct of the grossest kind". Although never completely rid of the allegations (even up to fifteen years later), in 2007 Stagg had received over £700,000 in compensation, and after new D.N.A. evidence arose, Robert Napper, who was (and still is) incarcerated in Broadmoor prison, was found guilty of her manslaughter. Colin Stagg had also received a full apology from the police.
