The 28-year old Garryowen rugby player was shot dead in a case of mistaken identity by the Dundon-McCarthy criminal gang.
Mr Geoghegan, who had no links with crime, sustained several shots to his body and head as he walked home from a friend’s house in Dooradoyle, Limerick, on Nov 9, 2008.
He died instantly in the gun attack just metres from the home he shared with his girlfriend, Jenna Barry.
He was the unintended victim of a shooting meant for another man, named as John ‘Pitchfork’ McNamara, who lived near him at Clonmore, Kilteragh.
Last month, senior gangland figure John Dundon, was sentenced to life in prison for the murder.
The Special Criminal Court ruled that evidence in Dundon’s trial pointed “overwhelmingly” to his guilt in directing and organising the murder.
Dundon’s carelessness in describing the real target to gunman, Barry Doyle, was what caused the death of an innocent person, the non-jury court heard.
Doyle, aged 23, from Portland Row, Dublin, is also serving a life sentence for the murder, having been convicted in 2012.
Dundon, aged 30, of Hyde Rd, Limerick, had pleaded not guilty and tried several times to delay his trial.
Dundon had gone to the High Court and Supreme Court in an attempt to defer his trial until next year. He also went on hunger strike in protest at the failure to have his trial delayed. He fainted on two occasions as his trial was about to get under way. He also appeared in court half-naked and in a wheelchair. He sacked his legal team, represented himself, then later hired other legal representation.
April Collins, the ex-partner of Dundon’s brother Ger — with whom she has three children — turned state witness. It was her direct evidence which was key in putting Dundon away.
According to John Dundon’s solicitor, John Devane, the Limerick criminal may appeal the conviction.
It is unclear if Mr Geoghegan’s family will attend today’s inquest.
A Garda spokesman said Mr Geoghegan’s inquest was listed to go ahead today.
“I expect it will open and that it will be finalised without any adjournments.”
