The verdict is due to be delivered today on the trial of three young men accused of murdering Dublin teenager, Mr Brian Mulvaney.
The jury retired to a hotel yesterday evening after deliberating for three hours but failing to agree a verdict.
At the Central Criminal Court, Mr Justice Barry White told the jury that they must consider whether the State's contention that each of the three intended to cause serious harm to the victim when they took part in a 'common design' to assault him is proven.
Mr Brian Willoughby (24) Orwell Park, Templeogue, Mr Neal Barbour (20) Domville Road, Templeogue and another teenager, who cannot be named for legal reasons, have pleaded not guilty to the murder of Mr Mulvaney on March 11th, 2000 at Templeogue.
Mr Mulvaney died from the inhalation of blood after he was found lying on the roadside with severe head injuries. The three accused admit they attacked Mr Mulvaney, but contend they never intended to cause his death.
