A man who was jailed for murdering a schoolgirl has died after being found unconscious in his cell, the Prison Service said.
Paul Hutchinson, who in January was jailed for life after he raped and strangled Colette Aram in 1983, was found in his cell at Nottingham Prison on Sunday morning and could not be woken by staff.
Emergency services were called but 52-year-old Hutchinson died on the way to hospital.
A Prison Service spokeswoman said: "HMP Nottingham prisoner Paul Hutchinson was found unconscious in his cell at 8am on Sunday. Paramedics were called and tried to resuscitate him but he died at 9.58am while being taken to hospital in an ambulance.
"As with all deaths in custody, the Prisons and Probation Ombudsman will conduct an investigation."
Colette was 16 when she was murdered and sexually assaulted by Hutchinson in 1983.
He was jailed for her murder in January, following a 26-year hunt by detectives.
In an unrelated incident, a 31-year-old man who was jailed indefinitely for public protection was found hanging in his cell, the Prison Service said.
Kenneth Bates, who was told he must serve a minimum of five years for wounding with intent and causing grievous bodily harm, was found in his cell at the Category C Gartree jail in Market Harborough, Leicestershire, on Sunday.
A Prison Service spokeswoman said: "HMP Gartree prisoner Kenneth Bates was found hanging in his cell on Sunday October 10. Staff and paramedics attended and attempted to resuscitate him; however he was pronounced dead on at 8.35am. As with all deaths in custody, the Prisons and Probation Ombudsman will conduct an investigation."
