A full DNA profile has been established of a newborn baby who was found dead on a beach in Co Kerry almost 34 years ago.
The baby boy - known as Baby John - was found at White Strand beach in Cahersiveen on 14 April 1984. The infant had suffered a number of stab wounds.
A blood sample taken at the time was preserved by gardaí and recently members of the Forensic Science Laboratory were able to generate a full DNA profile.
It is hoped that this profile may lead to the child's mother and father being identified.
The development comes as gardaí make an appeal for information in Cahersiveen on the case.
Members of the Garda Cold Case Unit and detectives from Co Kerry have been working on the case.
The original investigation into the death of Baby John, and the subsequent discovery of the body of a second baby on a farm near Abbeydorney outside Tralee in Co Kerry, led to a Tribunal of Inquiry in 1985 into the garda handling of the case.
The Tribunal was set up after a woman from Abbeydorney - Joanne Hayes - who had given birth to a different baby was questioned by gardaí about the baby found at Cahersiveen.
The Tribunal found that Ms Hayes was not the mother of the the Cahersiveen baby, as she had always maintained.
The DNA profile of the baby recently generated has also confirmed that Ms Hayes is not the mother of this child.
News of the DNA profile has been communicated to Ms Hayes and her solicitor.
Gardaí are appealing to anyone who was in Cahersiveen and surrounding areas in April 1984 to contact them if they have any information about the case.
