Murder by addict Gareth Wyn Jones 'learning points' review
The case of a heroin addict murdering a vulnerable man in Cardiff just five days after coming out of prison has been reviewed by the probation service.
Gareth Wyn Jones, 28, hit David Alun Lewis 100 times demanding his bank card number, leaving his body in a river.
He was sentenced to a minimum of 20 years at Cardiff Crown Court in October for the attack in March 2014.
The Ministry of Justice says a review carried out by the probation service had "identified some learning points".
Jones's trial heard he had only just been released from half of a six-year sentence for stabbing his girlfriend in the head with a fork.
The court heard Jones, who had fantasised about killing someone before, picked out Mr Lewis as easy prey at a hostel - just 90 minutes before killing the Ystrad Mynach singer-songwriter.
After the "sustained and brutal attack" on Mr Lewis, the jury was told Jones strangled his victim and left his body in the River Taff.
Jones had pleaded guilty to manslaughter, but denied murder on the grounds of diminished responsibility. A jury unanimously found him guilty.
He was given a mandatory life sentence and ordered to serve a minimum term of 20 years before being considered for release.
A Ministry of Justice spokesperson said: "Our deepest sympathies go to the victim's family following this abhorrent crime.
"Public protection is our priority and we are determined to have the best possible systems in place to supervise offenders in the community.
"We work hard to manage risk but sadly it can never be completely eliminated.
"As with any case involving a serious further offence, a review was carried out by the Probation Service. The review identified some learning points for the management of future cases."
