A prisoner has died in hospital after she was found unconscious in her cell.
Ruth Murphy, who was serving a life sentence for killing her seven-year-old son, was found by guards at the Dochas Centre in Mountjoy Prison in the early hours of Wednesday morning.
Murphy, 48, was taken to the Mater Hospital in Dublin, where doctors pronounced her dead soon afterwards.
Two separate Garda and Prison Service investigations are now under way.
It is understood Murphy committed suicide.
Her son Karl drowned on a beach in Greystones, Co Wicklow, nine years ago.
Murphy pleaded guilty to the murder in June 2004.
