Robert Coello inquest: Killer Lee Foye 'unlawfully killed' inmate
A child sex offender was unlawfully killed by a fellow inmate in his prison cell, an inquest jury has found.
Convicted killer Lee Foye, 28, was jailed for life in 2011 for the murder of Robert Coello, 44, at HM Prison Grendon in Buckinghamshire.
Beaconsfield Coroners Court was told Foye confessed "violent fantasies" just before the attack.
But a doctor who led an inquiry into the killing said this did not mean the murder could have been predicted.
Foye beat Coello, of Whitley, Reading, to death in a "ferocious attack" in the victim's cell in August 2010 and will serve a minimum of 35 years.
NHS England ordered an inquiry into the death and whether the confrontation between the inmates could have been avoided.
Dr Susan Williams, who led the review, told the court it may have been possible to help Foye with his anger if the prison authorities had known about all the warning signs.
HMP Grendon, near Aylesbury, tries to rehabilitate violent criminals through group therapy.
