Update 2.05pm: Donal Colgan has been giving his account of what happened on the night of the alleged murder.
He said he went into his local takeaway for a bag of chips after drinking up to 12 pints of cider in a nearby pub.
He claimed David Sheridan and another man called Gary Kinlan gave him a beating outside the chipper after some words were exchanged.
The 65-year-old, who once served in the British army, said he felt humiliated. He said he grabbed a knife from his home and went back to the chipper.
He told the jury he’d no intention of using it but thought to himself: “ye won't do this to me. I’ve to live here. I’ve to walk these streets”.
He said his “head went” after Mr. Sheridan attacked him again, but had no recollection of stabbing him in the stomach. He said he didn’t think he’d done any damage and couldn’t believe it when he found out he was dead.
The trial continues.
Earlier: A 65-year-old man accused of murdering a man outside a chipper in Dublin has told his trial he was having a panic attack on the night in question.
Donal Colgan, of Killarney Court, Killarney Street in Dublin 1, denies murdering David Sheridan on North Strand Road in August 2014.
From the stand, Donal Colgan described a troubled childhood – both at home and in school.
He said he grew up in Dublin’s north inner city and was educated in a Christian brother’s school where he was regularly beaten.
He got married in 1972 but separated 25 years later. He described himself as a loner who suffers from depression and panic attacks.
On August 17th 2014, he said he drank 12 pints of cider in his local pub and went for a bag of chips on his way home.
David Sheridan came into the chipper with his friend Gary Kinlan. Mr. Colgan said he didn’t know them and chose to ignore some sort of remark they made about him.
Outside, he claims Mr. Kinlan squared up to him and hit him five or six times in the face. He said Mr. Sheridan then came out and kicked him a few times. He said he collapsed after being hit in the head with a bag of bottles.
It is the prosecution’s case that he then went back to his flat and armed himself with a kitchen knife which he used to repeatedly stab David Sheridan with.
He denies the charge.
