The family of a man murdered 24 years ago have said "catastrophic failings" of the probation service enabled his killer to strike again.
Brian Whitelock, 57, has been given a whole life sentence, meaning he will never be considered for parole, for the drug-fuelled and "brutal" murder of "bubbly and caring" retired riding instructor, Wendy Buckney.
He had moved into a flat across the road in Clydach, Swansea, from the 71-year-old after serving 18 years in prison for murder and manslaughter, including killing his own brother.
It is understood a multi-agency review will now take place to discover if authorities missed opportunities to protect the public from the double killer.
The Probation Service has been asked for comment.
