Quyen Ngoc Nguyen's killing followed failings by authorities
Two murderers who were freed from prison went on to rape, torture and kill a young mother after numerous failings by police and the probation service, an inquest has concluded.
Stephen Unwin and William McFall, who is originally from Greencastle, in Co Antrim, were supposedly under supervision and strict licence conditions when they murdered Quyen Ngoc Nguyen, a 28-year-old Vietnamese woman in 2017.
The mother-of-two was burnt alive in her car after hours of rape and torture in August 2017, which saw the killers extract her PIN number to steal cash before cooking and eating a curry as she lay incapacitated on the floor.
Coroner Derek Winter concluded that the unlawful killing of Ngoc Nguyen, in Houghton-le-Spring near Sunderland, followed failings by police and the probation service.
An inquest at Sunderland Coroners' Court heard the authorities had not shared information with each other about breaches of licence conditions.
Even before the brutal murder, Unwin and McFall were running a criminal enterprise.
Unwin had previous convictions for burglary and arson, while McFall has been convicted of numerous offences including for robbery, arson, and possessing firearms and offensive weapons.
The two men were already serving life sentences for brutally murdering pensioners in their homes during the course of unrelated burglaries when they met in prison as cellmates.
But they were both judged suitable for release on licence in 2010 and 2012 respectively and made contact again in 2016.
Unwin and McFall were both given whole life terms for murder in April last year.
