Anthony Kelly, aged 50, of O’Malley Park, Southill, denies possession of a semi-automatic pistol with intent to endanger life, on October 28, 2009.
It is the state’s case that Mr Kelly shot his daughter’s now ex-boyfriend Michael Lynch, aged 27, of O’Malley Park.
Mr Lynch received a gunshot wound to the back which exited his body though his chest.
Of the 19 CCTV cameras located in Southill, only one was not working on the morning of a shooting outside the accused’s house: the camera situated outside Mr Kelly’s front door.
The jury in the trial at Limerick Circuit Court has been told a number of overgrown trees may have been blocking the camera’s signal.
Last week, the jury heard the CCTV camera was not working properly.
However, Brendan Nix, SC for Mr Kelly, said this was not the case.
He said it had come to his attention that certain trees had blocked the digital signal being sent from the camera to the offices of the Limerick Regeneration Agencies in Roxboro.
Yesterday, Mr Nix was granted an application to visit the building to examine the digital camera receiver and to inspect the line of sight from the camera in Southill to the regeneration building rooftop.
Mr Nix and state prosecutor John O’Sullivan, along with Mr Kelly’s solicitor, John Devane, and a number of gardaí travelled 6km from the court to the regeneration building and back to court, to view the receiver.
The jury was told that Mr Nix, Mr O’Sullivan and gardaí climbed a steep ESB-type ladder to the rooftop.
Sergeant John Delaney of Henry street Garda Station told the court the trees in question had been cut down in November 2009, a month after the alleged shooting.
Earlier in the trial, the jury heard that Mr Kelly repeatedly told gardaí he would be exonerated by CCTV footage of the incident. During several interviews following his arrest he told gardaí to view the footage and said he would be “shocked” if it was not working.
The trial continues.
