The trial has previously heard that Philip Collopy allegedly received a phone call from John Dundon on the morning of the shooting, informing him that the wrong man had been killed.
Mr Dundon, aged 30, of Hyde Road, Limerick, has pleaded not guilty to murdering Shane Geoghegan, aged 28, at Clonmore, Kilteragh, Dooradoyle, on Nov 9, 2008.
The court has heard that Mr Geoghegan died at the scene of gunshot wounds to his head and body.
Yesterday, retired detective garda Sean Lynch told the non-jury court he went to the scene of the shooting that morning.
The court was shown CCTV footage of four men walking on Cruises St in Limerick, over a week before the shooting.
He identified the four men as John Dundon, Philip Collopy, his brother Kieran Collopy and Barry Doyle, who the court heard was convicted of the murder of Mr Geoghegan.
He told the court two individuals he knew called Phillip Collopy and his brother Kieran arrived at the scene. He said Phillip Collopy handed him his mobile phone, which he put into a self-sealing evidence bag.
The three-judge court heard Philip Collopy subsequently died in an accident.
Prosecution witness April Collins, aged 26, previously told the court that she, her then partner Ger Dundon, John Dundon and Barry Doyle, met in the car park of a pub in Limerick at around 6.30am on the morning of Nov 9, 2008.
She said it was just hours after Mr Geoghegan was shot dead in a case of mistaken identity near his home in Dooradoyle, which was four doors down from the home of the intended target John McNamara.
Ms Collins who is the former girlfriend of the accused’s brother Gerard, previously told the court she witnessed John Dundon ordering Barry Doyle to kill a man called Johnny Mac.
She said John Dundon was “very excited in himself” and was saying “Johnny Mac is dead. We got him”.
April Collins’s sister, Lisa, who is another prosecution witness, was recalled to the stand yesterday for cross-examination by the defence.
Brendan Nix, defending, asked her about a Crimecall reconstruction of Mr Geoghegan’s killing which was screened on RTÉ on Nov 18, 2008.
Mr Nix said the programme was “very moving” as the family were involved, and she agreed that she had seen it but had made no comment when interviewed by gardaí in Feb 2009.
“I was afraid to say anything,” she told the court.
Victoria Gunnery told Sean Guerin, prosecuting, that she was Barry Doyle’s girlfriend in 2008 and that they had a child together.
She said after her boyfriend moved to Limerick in Aug 2008, they maintained contact by phone and she gave the mobile numbers she said they used to gardaí.
The court directed the passport office to make any particulars on file relating to the accused available.
His legal team believes details of a passport he held in 2008 could have a bearing on the case as it showed the accused’s comings and goings.
An official from the passport office is expected to give evidence in the case when the trial resumes on Tuesday.
Mr Nix told the court that John Dundon uses his mother’s surname ‘McCarthy’ as his parents never married.
The trial continues.
