Murder of Shane Geoghegan

The trial of Barry Doyle resulted in a hung jury after one of the longest deliberation in Irish legal history. Due to the fact that according to his defence counsel Martin O'Rourke SC, his confession was due to threats and inducements made while in custody. On 15 February 2012, following a re-trial, Barry Doyle was convicted of the murder of Shane Geoghegan, in which he pleaded not guilty. The jury of three women and eight men returned a unanimous guilty verdict, after deliberating for six hours.

On 18 August 2012, John Dundon from Limerick City, was also charged with the murder at the Special Criminal Court. He was found guilty on 13 August 2013 and sentenced to life in prison.

Twenty-three-year-old Barry Doyle from Portland Row, Dublin but living in Limerick was subsequently charged with the murder. He was put on trial in the Central Criminal Court in February 2011. Doyle was believed to be working on behalf of the McCarthy-Dundon gang and allegedly shot Geoghegan in a case of mistaken identity, thinking he was a criminal linked to the Keane-Callopy gang.

There was an artistic tribute to Geoghegan in November 2011.

Limerick County Council hosted a civic reception for Shane Geoghegan on 12 July 2010. A memorial plaque was unveiled in the county council building's foyer. The next day a major charity match was held at Thomond Park – Sunderland A.F.C. versus Munster XI, with funds going to the Shane Geoghegan Trust.

Up to 200 Gardaí worked on the murder enquiry, with 50 officers dedicated to the case on a daily basis. Searches were carried out resulting in seizures of handguns, ammunition and drugs. One of the leaders of the McCarthy-Dundon crime family handed himself in to Gardaí in the week following the shooting out of fear of being murdered. During the investigation, some of the suspects were tracked via their Bebo pages. Social networking sites were identified as a problem in glorifying gun crime. In March 2009, Gardaí arrested 15 people in connection with the shooting.

Then Justice Minister Dermot Ahern made a statement to Dáil Éireann following the killing. National public opinion demanded strong action from the Government. Local TD and Minister for Defence Willie O'Dea, came under pressure to secure changes to the law and greater resources to tackle Limerick city's gangland crime. As a result, the Justice Minister introduced the Criminal Justice Bill 2009.

A charity was launched in honour of Shane Geoghegan in October 2009 by his mother and former Ireland soccer international and CEO of Sunderland AFC Niall Quinn. Its aims are to provide children with an alternative to criminal or anti-social behaviour by making a range of sporting and creative activities accessible to them. The trust is based on the Sunderland AFC foundation which helps children in vulnerable communities by getting them involved in sport.

Shane Geoghegan (7 March 1980 – 9 November 2008) was an Irish rugby player for Garryowen who was shot and killed in a case of mistaken identity as part of a gang feud in Dooradoyle, a suburb in the city of Limerick, Ireland. The murder took place in the early hours of Sunday morning, 9 November 2008. He had no links with organised crime gangs.
