A 24-year-old man has admitted stabbing a fellow inmate to death at Mountjoy Prison Dublin in January 2004.
Stephen Wall, Shankill, Co Dublin, pleaded guilty at the Central Criminal Court to the manslaughter, but not guilty to the murder of Alan Green at the prison on January 27th.
That plea was accepted by the State and Mr Justice Paul Carney remanded Wall in custody for sentence on December 18th. He also ordered the drawing up of a victim impact report.
The body of Green (30), from Bray, Co Wicklow, was discovered shortly after midday, when prisoners were collecting their lunch.
He had a serious stab wound to the chest.
He was rushed to the Mater hospital but attempts by ambulance staff to save his life failed and he was pronounced dead later that afternoon.
In April last year Wall was formally charged over the killing.
The victim had been serving a 12-month sentence for unlawful possession of drugs, and was due to be released two months after he was killed.
He had been in and out of prison many times, mostly for minor offences.
