Two Limerick men have gone on trial at the Special Criminal Court for the murder of businessman Roy Collins, five years ago.

Wayne Dundon (35) of Lenihan Avenue, Prospect and Nathan Killeen (23) of Hyde Road, Prospect deny killing Mr. Collins (35) who was shot once in the chest at the amusement arcade he ran at the Roxboro Shopping Centre, on April 9th in 2009.

The prosecution alleges Wayne Dundon organised Roy Collins's murder from behind bars and that Nathan Killeen was the driver.

A third man, who is not before the non-jury court, was the gunman.

Opening the trial Michael O'Higgins SC said the prosecution is relying mainly on the evidence of five of the accused's associates, some of whom he described as criminal associates.

One man, Gareth Keogh will testify that Nathan Killeen and Wayne Dundon tried to pressurise him into driving a car as part of the 'whack', and that he turned down an offer of €20,000

Another witness Anthony 'Noddy' McCarthy was in Wheatfield prison serving a life sentence for the murder of Kieran Keane.

The court heard on the day of the shooting he will recall walking across the hall from his cell to a hyper Wayne Dundon who was shouting on the telephone: ''You better do it for us. You never do nothing for our family. You and your mother will be sorry".

He will testify that when the call ended, Wayne Dundon told him that he had directed James Dillon ''to go down and do Collins'' and he complained about that ''muppet'' Gareth Keogh who ''wouldn't drive the car either''.

It is the case of the prosecution that Wayne Dundon and Nathan Killeen were part of a joint enterprise to murder Roy Collins.

Mr. O'Higgins said they have ''very strong circumstantial evidence'' in terms of people's movements before and directly after the shooting.
