Closing speeches have begun in the trial of a man who denies murdering another man as he pushed his baby son in a pram.

Wayne Cooney, 31, with an address at Glenshane Drive in Tallaght, has pleaded not guilty to the murder of 22-year-old Jordan Davis at a laneway near a school in Darndale in north Dublin on 22 May 2019.

He has also denied possessing a semi-automatic pistol and ammunition.

The prosecution alleges that Mr Cooney approached Mr Davis on a bicycle at 4pm on 22 May outside Darndale Church and shot him three times as Mr Davis was pushing his four-month-old son in a pram.

Prosecuting Counsel Bernard Condon has told the jury that the ultimate inference he is asking them to draw is that the person who fired eight bullets, three of which catastrophically injured Mr Davis, is Mr Cooney.

He told them the circumstances were such that there was no alternative view that was rational, sensible or based on evidence other than that Mr Cooney was the killer.

He said the catalogue of coincidences and strange events that had collided in this case were such that either Mr Cooney was responsible or he was the most unlucky person ever.

Mr Condon said the case was based predominantly on circumstantial evidence. He has been outlining what he described as a series of "extraordinary" coincidences to the jury.

Mr Condon told the jurors it was up to them what their tolerance for coincidence was. He said it was their responsibility to decide the case on the evidence. He said he was inviting them to follow the logic to its logical conclusion and find that Jordan Davis was murdered by Wayne Cooney.

Defence Counsel, Giollaíosa Ó Lidheadha said it was an extreme experience for the jurors to see on CCTV, a human being being gunned down with a baby being pushed along.

But he said, just because this was a horrifically callous and horrible murder, it would be another tragedy upon that, if the emotional outrage and revulsion overtook and supplanted a careful consideration of the evidence.

Mr Ó Lidheadha said the prosecution had mixed together items of real circumstantial evidence along with matters that were not of real significance and had given the jurors a long list of so-called coincidences.

He said they may have views about the drugs trade, but they should fairly analyse the evidence in this case without bringing baggage to it.

He also said they should not find Wayne Cooney guilty because he was associated with a person who had previously threatened Jordan Davis. It was a dangerous logic to find someone guilty because of their association with someone else, he said.

He said they should decide the case on the evidence.

The jurors are likely to begin considering their verdict tomorrow.
