A man brought up in Huddersfield is likely to die in jail after another double murder conviction.

Mark Nash, 42, has been found guilty of an horrendous double murder in Dublin, which happened almost 20 years ago.

The former Bradley schoolboy was already serving a life sentence for a previous double murder.

He was handed a life sentence this afternoon after a jury had spent a little over four hours deliberating at the end of a 48-day trial.

They found convicted killer Nash - a former student at All Saints High School - guilty of the “cold case” murder of two women, whose mutilated bodies were found in their sheltered accommodation in Grangegorman in Dublin.

Nash was already serving a double life sentence in Arbour Hill Prison, where he has been held since October 1998 for murdering two people in Ballintober, Castlerea

in Roscommon and leaving Sarah Jane Doyle seriously injured in mid-August in 1997.

Ireland has no minimum tariff for jail sentences and life normally sees prisoners serve between 18 and 20 years before they can apply for parole.

But one man has already spent more than 50 years behind bars for murder.

Nash had been living in Prussia Street and Clonliffe Road in Dublin before his killing spree.

He pleaded not guilty at Dublin’s Central Criminal Court to the murder of Sylvia Sheils, 59, and Mary Callanan, 61, between March 6 and March 7, 1997.

From the outset the trial was set to last six to eight weeks but instead it continued for 48 days during which the jury heard evidence from 71 witnesses including Gardai attached to the Bridewell Garda Station in Dublin, Mill Street Garda Station in Galway, the National Bureau of Criminal Investigations (NCBI) at Harcourt Square, Mountjoy

Prison and the Forensic Science Ireland (FSI).

It was a case mired in controversy, as another man was originally charged with the murders of the two women.

Nash had been arrested In August 1997 for the murders of Carl Doyle and his wife Catherine, when he was just 25.

During his interview, he said that about three monnths prior to his arrest, he had broken into a house through the back, and had stabbed two women in their sleep.

Nash’s confession caused some consternation amongst the gardaí, as Dean Lyons had been charged at that point and was on remand awaiting trial.

In August 1997, the Garda Commissioner appointed Assistant Commissioner James McHugh to carry out a review of the available evidence and in light of his findings, .Nash was formally charged with the two mruders in In October 2009.

During the trial Mr Justice Carroll Moran told the eleven jury members that the prosecution’s case was based on three things; the admissions made by the accused, the print of the caterpillar boot found in bedroom number one of Orchard View and finally the scientific evidence and DNA.

It was the prosecution’s case that there was 13 confessions made by Nash to the Grangegorman murders and all were consistent from beginning to end.

In 2009 advances in DNA techniques found traces of the victims on a velvet jacket belonging to Nash.
