‘Monster Mansion’ assassin suffers ugly dying behind bars after inserting spike into chest
Karl Quincey, 48, told prison officers ‘it’s been bubbling for a while now’ after inserting a glasses arm into a self-inflicted wound at HMP Wakefield. An inquest recorded a verdict of suicide
A convicted killer passed away in hospital six days after he pushed a makeshift spike into a self-inflicted chest wound whilst in his cell at HMP Wakefield. Karl Quincey, 48, had a lengthy record of self-harm and was kept under round-the-clock surveillance during his stint at Wakefield, according to a Prison Ombudsman report.
The West Yorkshire high-security jail has earned the nickname “Monster Mansion” due to the number of dangerous murderers and sex offenders housed there. Quincey had previously and repeatedly shoved metal rods and wood into his open chest wounds on multiple occasions.
After he had pushed the glasses arm into the wound in his chest, Quincey was questioned by an officer about his actions and he replied, “it’s been bubbling for a while now”, reports Yorkshire Live.
Quincey appeared remarkably composed and continued vaping as he paced around the cell. Paramedics rushed Quincey to Leeds General Infirmary.
Whilst being escorted to the ambulance, the prisoner managed to force the glasses arm deeper into his chest. During his hospital stay, Quincey declined any surgery to extract the glasses arm and voiced his wish to die.
He subsequently died from sepsis. Quincey was handed a life sentence, with a minimum term of 17 years, in 2010.
He had knifed a man 11 times in the neck in Devizes, Wiltshire. He reportedly told a prison guard that he killed the man “under the influence of Satan”, according to reports at the time.
The Prisons Ombudsman revealed that Quincey had been diagnosed with emotionally unstable and dissocial personality disorders. He had a significant history of self-harm, which included cutting and inserting multiple objects into an open chest wound.
He had previously been held in Broadmoor Hospital, a high-security psychiatric hospital, before being transferred to Wakefield Prison in July 2023. Tragically, he succumbed to sepsis in hospital on October 21 that year.
The Ombudsman praised the management of suicide and self-harm procedures while Quincey was at Wakefield. The report stated: “Managing Mr Quincey’s behaviour and risk was challenging for prison and healthcare staff and we found that they took positive actions to support him while at Wakefield.
“Suicide and self-harm procedures were generally well managed, with a consistent case co-ordinator and regular input from the mental health team.” However, it also highlighted shortcomings, stating: “However, there was limited senior multidisciplinary input into managing and mitigating Mr Quincey’s risk – particularly towards the end of his life when changes were made that should have been recognised as potential triggers for suicide and self-harm – and the Safety Intervention Meeting, which should provide this support, was often poorly attended and provided little guidance to the case review team.”
The Ombudsman has formulated an action plan with suggestions for Wakefield prison following Quincey’s incident. An inquest into Quincey’s death wrapped up in November, ruling the cause as suicide.
Quincey had tried to challenge his “unsafe” conviction back in 2011, but was denied.
