The family of a man murdered by his nephew claim new information about the case proves more could have been done to prevent his death.
Zaheer Aziz, 44, murdered his uncle, Shabir Choudary, 27 days after being released from prison in January 2010.
Aziz had been serving an eight-year sentence for attacking two drug users with a scythe and for supplying heroin before being released on licence. After Mr Choudary, 52, gave him a place to stay, Aziz killed him with a kitchen knife at Gill Sike Grove, Thornes.
In August last year, it emerged that Aziz could have been sent back to prison before the murder if his level of risk had been properly assessed by West Yorkshire Probation.
On Wednesday, his family were given details of a summary of a Serious Further Offence Review into the case under new regulations on disclosure.
Nesar Rafiq, Mr Choudary’s nephew, said a pre-release report on Aziz was not as thorough as it should have been because of a lack of resources and staff being off sick.
He said: “Will cutbacks to probation mean more lives being lost?”
Mr Rafiq said no action was taken about threats Aziz made to his family while in prison in 2008 and 2009.
He said: “They simply did nothing with this information. I personally believe he would have killed other family members.”
Details of aggressive and drunken behaviour which led to Aziz losing his bed in a hostel also came to light.
Mr Rafiq said: “I was hoping this would give us peace of mind but instead it makes us even more determined to get to the truth.”
West Yorkshire Probation declined to comment on details of the meeting.
Director of operations Mark Siddall said: “West Yorkshire Probation Trust is committed to protecting the public and reducing re-offending.
“The responsibility for this crime lies solely with Zaheer Aziz. Unfortunately risk can never be completely eliminated but we are determined to have the best possible systems in place to effectively manage offenders in the community.”
