A man who murdered three children at a house in Worcester has been cleared for release after serving 45 years behind bars.
David McGreavy was sentenced to life and ordered to serve a minimum of 20 years in prison 1973.
He was convicted of killing Paul Ralph, four, and his sisters Dawn, two, and nine-month-old Samantha in their Worcester home.
On 13th October 1973, the 21-year old unemployed labourer was left to babysit the children while their father Clive Ralph went to pick up his wife from work.
When Mr Ralph returned shortly before midnight all four of them had disappeared and the alarm was raised.
At 1:20am a police officer found the three children's bodies impaled on a spiked metal fence in their neighbour's back garden.
He claimed he killed the children because one of them would not stop crying, and was sentenced to life for the murders in 1973.
The Parole Board confirmed that a panel directed his release following an oral hearing.
A document from the Parole Board about McGreavy's case referred to a victim personal statement from the victims' 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 a number of factors which make it less likely that Mr McGreavy will reoffend in future.
"These included his improved self-control and the fact that Mr McGreavy has learnt to remain calm in stressful situations.
"He has also shown himself to be compliant and co-operative with authority, which suggests that he will comply with licence conditions.
"A network of supportive friends in the community was also identified as a protective factor."
The Parole Board said: "Parole Board decisions are solely focused on whether a prisoner would represent a significant risk to the public after release.
"The panel will have carefully looked at a whole range of evidence, including details of the original evidence and any evidence of behaviour change.
"We do that with great care and public safety is our number one priority."
