A number of inquiries, launched by then Home Secretary, David Blunkett, investigated the failures of both the police and other social and vetting agencies, in stopping Huntley sooner, and system wide communication and intelligence-sharing errors were identified, which led to the suspension, and early retirement, of the chief of Humberside Police.
Since being jailed, Huntley has reportedly admitted to his father that he lied when giving evidence at his trial, alleging that he killed Jessica Chapman to prevent her from calling for help on her mobile phone, rather than suffocating her accidentally, as he claimed in court.
On 23 July 2004, Carr’s mother, Shirley Capp, was sentenced to six months in jail for intimidating a witness during the trial. Capp’s neighbour, Marion Westerman, had told police that she had seen a crying Carr, and Huntley, looking in the boot of a car outside Carr’s mother’s house, shortly after 10-year-old Holly Wells and Jessica Chapman had gone missing.
Carr’s mother’s threats to Westerman had nearly resulted in her retracting her statement at the time, and not testifying in court.
On 5 September 2006, Ian Huntley was rushed to hospital after being found unconscious in his prison cell. He was taken to Pinderfields Hospital in Wakefield to receive treatment for a suspected drug overdose and was returned to prison the next day.
Following this incident the Home Office released a statement to the media: "Huntley continues to be managed according to Prison Service policy on the prevention of suicide and self-harm. In particular he will be subject to Assessment, Care in Custody and Teamwork (ACCT) procedures through which his risk will be continually assessed. The Prison Service works to minimise the risk of any prisoner taking their own life, but it cannot eliminate that risk entirely." Huntley had been considered a suicide risk after he took 29 anti-depressant pills, which he had hidden away in a box of teabags, in June 2003.
