Gary Flynn of Rossfield Drive in Tallaght has pleaded not guilty to the murder of Seamus 'Shay' O'Byrne at Tymon North Park on March 13, 2009.
At his trial today at the Central Criminal Court Detective Garda Michael McGrath said he collected a "substantial" amount of CCTV from the area relating to the day of the shooting and the previous day. He presented some of that footage to Justice Patrick McCarthy and the jury of nine men and three women.
Speaking to prosecuting counsel Alex Owens SC, he said through his trawl he collected footage of a Ford Transit Van, a red Honda Accord and a white Nissan that were traced on March 12 travelling on the Naas Road into two car parks at the Red Cow Hotel and into a number of garages and shops in the area. He said gardai were interested in these vehicles as part of their investigation into Mr O'Byrne's murder.
He used speed cameras, car park CCTV and camera footage from inside various shops and garages.
On March 12 at 7.28am he said footage taken from a garage on the Naas Road shows Eugene Cullen from Crumlin arriving in a Ford Transit van and buying a green petrol can and filling it with petrol. He then put the can into the back of the Ford Transit.
Gardai then tracked the van as it traveled along the Naas Road to the Red Cow Hotel. A white Nissan is also seen at the same location.
CCTV taken from a Spar at Brennanstown showed another man, Garret O'Brien, arriving in a red Honda Accord. He said Mr O'Brien was wearing a New York Yankies baseball cap and a blue zip-up hoodie.
A second man with him was wearing a grey jumper with a Nike emblem and blue jeans. He said Mr O'Brien bought a number of items including a packet of crisps.
Footage was also taken from garda speed cameras on the Naas Road which showed the Nissan Micra travelling by the Red Cow hotel shortly after 8am.
A later video at the back of the Red Cow Hotel shows the Ford van, a Blue Passat and the Nissan Micra there at the same time. "There appears to be an interaction between them," said Det Gda McGrath.
On the day of the alleged murder, a speed camera shows the Nissan Micra at 8.18am with a driver wearing a dark top and a white tip around the neck, the same as Garret O'Brien had worn the previous day. It traveled to the Red Cow car park back entrance and is joined by the Volkswagen Passat.
Mr Owens has told the court that it is the prosecution's case that Mr Flynn was part of a "murder gang" that plotted to kill Seamus O'Byrne.
The trial continues Thursday.
