Almost 33 years since his discovery, a DNA profile has been established for a baby found on an Irish beach in 1984.
The male infant was found on White Strand beach in Cahersiveen, Kerry, on April 14 of that year.
The baby, called Baby John by authorities, had suffered a number of stab wounds which led to his death.
A blood sample was taken at the time and was preserved by Gardaí.
Members of the Forensic Science Laboratory have now been able to generate a full DNA profile using this sample.
The Garda Síochána's cold case unit is reviewing the death.
Gardaí are appealing to anyone who was in Cahersiveen in April 1984 to come forward if they have any information about the case.
