John Dundon (30) is one of the main leaders of the McCarthy/Dundon gang – the most infamous mob in the history of the State.
Before this morning's murder conviction, father-of-two Dundon was jailed for five and a half years last April for making threats to kill April Collins in Limerick city – she would later turn State witness against the Dundon mob.
Dundon, who has more than 40 previous convictions, was previously jailed for threatening to kill during a courtroom incident at his brother Dessie's trial for murdering Kieran Keane, and for threatening to burn down the home of a prison officer whose car was later found burnt out.
Shane Geoghegan (28) was a talented and popular rugby player who played for Limerick's famous Garryowen rugby club in Limerick.
He had absolutely no involvement in crime and was the victim of mistaken identity when he was shot dead by Barry Doyle near his home in November 2008.
Shane was completely devoted to his girlfriend Jenna Barry and his savage murder caused so much outrage that thousands of people lined the streets of Limerick for his funeral.
Hitman Barry Doyle (28), right, is serving a life sentence for the murder of Shane Geoghegan. Originally from north inner city Dublin, Doyle moved to Limerick and linked up with the McCarthy/Dundon gang after his brother Paddy was shot dead in Spain in 2008.
Gardai believe that Barry was cultivated and used by the notorious gang as he tried to come to terms with the murder of his brother, who was a key henchman of the 'Fat' Freddie Thompson mob.
THE INTENDED TARGET
John McNamara, left,who is nicknamed 'Pitchfork', was the intended target of the brutal murder – he was a close associate of the rival Collopy crime family.
As well as getting his face sliced in Limerick city centre and being the victim of a pitchfork attack in the back, McNamara survived a gun attack in August, 2006.
His girlfriend's home was located only a few yards from the home of tragic Shane Geoghegan, in Door-adoyle, and this is what led Barry Doyle to shoot Shane Geoghegan by mistake.
April Collins (25), above right, gave key evidence against John Dundon at the murder trial and also gave important evidence that led to Wayne and John Dundon being convicted of threatening to kill her after she broke up with their young brother Ger.
She is currently in a relationship with convicted rapist Thomas O'Neill and her testimony at a separate trial led to the conviction of hitman Barry Doyle for the murder of Shane.
She has a number of previous convictions and, in May, 2011, was given a three-year suspended sentence for threatening a potential witness in a case involving the Dundons.
April Collins' older sister Lisa (29) also gave key evidence against John Dundon at the trial, saying she heard him plan the murder of John McNamara a couple of weeks before the murder took place.
Christopher McCarthy (29) also gave evidence. He said he was a first cousin of John Dundon and previously a key member of the gang.
He also said he didn't know what use Dundon had for the car that he asked him and Ms Collins to get.
In evidence, he recalled the night John Dundon and Barry Doyle came to his house: "He (Dundon) was saying: 'Pitchfork is dead'. I knew he was on about John McNamara."
