The three were found guilty following a 66-day trial at Dublin Circuit Criminal Court by a jury which also failed to agree on verdicts in the cases of two other men.
The three convicted men, who have been remanded in custody by Judge Tony Hunt for sentence later, are: Christopher Corcoran, aged 61, of Bayside Boulevard North, Sutton; Mark Farrelly, aged 37, of Moatview Court, Priorswood; and Jason Kavanagh, aged 34, of Parslickstown Court, Ladyswell.
The jury failed to reach a verdict on the charges against David Byrne, aged 36, of Old Brazeel Way, Knocksedan, Swords and Niall Byrne, aged 27, of Aughavanagh Road, Crumlin.
They had denied robbing €2.28m from Paul Richardson and Securicor and had also pleaded not guilty to falsely imprisoning members of the Richardson family – Marie Richardson and her sons, Ian (then 17) and Kevin (then 13) – on March 13 and 14, 2005.
Judge Hunt thanked the jury of seven men and four women for their work on the longest-running criminal trial in the history of the state and complimented them for the long hours they put into reaching verdicts. The jury had deliberated for 22 hours over three days.
Prosecuting counsel Denis Vaughan Buckley SC , asked for the men to be remanded in custody pending sentence in November.
Most of the hearing was held in Blanchardstown Courthouse and 260 witnesses were listed to give evidence.
Day-four of the scheduled trial was reached before the jury was finally assembled. Only 10 jurors could be selected on the first day, April 19, out of a panel of 150, and two more were on April 21 from a new panel.
Then, one of the selected jurors indicated that she couldn’t remain due to work problems and the start of the trial proper had to be adjourned to April 26 to have her replaced. The jurors were transported from the Four Courts to Blanchardstown and back again every day they sat.
The trial revolved around three main points of evidence, DNA tests, CCTV footage and mobile phone tracking.
Detective Inspector Martin Mooney told Mr McGinn that using call trace data from service providers he was able to draw up charts showing the times, duration and general location of many mobile phone calls between a small group of numbers during the course of the robbery. Most of them lasted well under a minute.
Det Insp Mooney said each call had to be routed through a particular mobile phone mast and whichever mast was used showed the general area of the caller.
The records showed several of the callers moving location rapidly and frequently throughout the night and early morning in Raheny, the Malahide Road, Baldoyle, Coolock, and Chapelizod as well as many others.
