Ipswich murderer Paul Clarke found dead in HMP Whitemoor
A double killer, convicted alongside a girl thought to be the UK's youngest female double murderer, has died.
Paul Clarke, 46, was found unconscious at HMP Whitemoor, Cambridgeshire, and could not be revived.
He was sentenced to life in prison with a minimum of 27 years after murdering Desmond Thorpe, 43, and Rosalyn Hunt, 41, in Ipswich in 2009.
Their daughter Lorraine Thorpe, was sentenced to a minimum of 14 years for her part in the double-killings.
A Prison Service spokesman said: "HMP Whitemoor prisoner Paul Clarke was found unresponsive in his cell by staff on Monday September 1. Paramedics attended but he was pronounced dead shortly before 6.30am.
"As with all deaths in custody, the Independent Prisons and Probation Ombudsman will conduct an investigation."
The bodies of Ms Hunt and Mr Thorpe were found at separate addresses, in Ipswich in August 2009.
Both Clarke and Thorpe had denied the charges and gave no evidence during their trial.
They had repeatedly beaten and tortured Ms Hunt and then smothered Mr Thorpe to death.
Speaking after the hearing, police described the killings as brutal and tragic.
During Thorpe's sentencing at the Old Bailey, Mr Justice Saunders said she had been influenced by Clarke, the "dominant" member of a group of heavy drinkers, and had been keen to impress him.
