The investigation into the death of a ten-year-old girl, whose body was found in a bog in Co Roscommon in August 1970, is to be reviewed.
Bernadette Connolly went missing on 17 April 1970. She had been out on her bicycle but failed to return to her home in Collooney in Co Sligo.
It is believed she may have been sexually assaulted before she was killed. Her remains were discovered in bogland near the town of Boyle.
A murder investigation was launched but no one was arrested or charged in connection with the child's murder.
The case was first reviewed in 2004 but no new lines of inquiry were pursued.
Garda Commissioner Fachtna Murphy has now appointed Assistant Commissioner Kieran Kenny to examine the file again following recent publicity in the wake of the publication of the Murphy Report.
It is believed the main suspect for the murder was a priest who knew the family but he has since died.
