A man who killed three children before their mutilated bodies.
David McGreavy killed Paul Ralph, four, and his sisters Dawn, two, and Samantha, nine months, in their Worcester home in 1973.
Paul had been strangled, Samantha died from a compound fracture to the skull.
McGreavy, a family friend and lodger, then impaled their bodies on the spiked garden at Gillam Street, Rainbow Hill.
He claimed to be crying, and was sent to life for the murders in 1973. He was 21 at the time and was dubbed the "Monster of Worcester".
McGreavy has spent 45 years in prison and a Word Board report said he had "changed considerably" during this time.
This week the Words Board confirmed that a panel had directed his release following an oral hearing.
Mother told he would never walk free
The children's mother, Elsie Urry, who has also been known as Dorothy The Sun: "What's this?" Moors Murderers did.
"But Ian Brady and Myra Hindley never left before they died so I know why the hell should he?
He put my babies on spikes for God's sake – he mutilated them and they gave them agony.
"I wanted him to be sick and he would never walk free again."
"I have now finally been betrayed."
McGreavy changed 'considerably'
A document from the Parole Board about McGreavy'S case referred to as a personal statement from the childrens' mother, "setting out the devastating effect that these deaths had on her and still do have".
The document said that over the 45 years in custody, McGreavy has changed "considerably".
It added: "He has developed self-control, as well as a considerable understanding of the problems that he has had and what caused them.
"The psychologist identified as a number of factors McGreavy will reoffend in future.
"These included his improved self-control and the fact that Mr. McGreavy has learned to remain calm in stressful situations.
"He has also been shown to be compliant and co-operative with the authority.
"A network of supportive friends in the community" was also identified as a protective factor. "
'Public safety is our number one priority'
The Parole Board said: "Words Board decisions are solely focused on if a prisoner would represent a significant risk to the public after release.
"The panel will have a clear range of evidence and evidence of behavior change.
"We do that with great care and public safety is our number one priority."
