David Mahon’s barrister has accused the prosecution of “grossly exaggerating” the fatal injury suffered by his stepson.

The 45-year-old is accused of murdering Dean Fitzpatrick outside his apartment at Northern Cross in Dublin in May 2013.

In his closing speech on Friday, Remy Farrell, senior sounsel for the DPP, accused David Mahon of lying to Gardai

He accused him of doing everything he could to cover his tracks and described his “suicide by stepfather” theory as a “fantastical suggestion”.

Today was the turn of Mr. Mahon’s barrister to speak to the six men and six women of the jury for a final time.

Sean Guerin began by suggesting that the case had all the hallmarks of a prosecution that’s striving come hell or high water to secure a conviction.

He said the use of the word “gutted” to describe the 23-year-old’s injury was a “gross exaggeration” designed to disgust the jurors and portray the accused as some sort of butcher or savage.

The judge will summarise the evidence and explain the law to the jurors once the defence has finished its closing speech.

They’ll then be asked to consider a verdict.
