David Mahon found guilty of manslaughter
David Mahon has been found guilty of killing his stepson Dean Fitzpatrick outside his apartment at Northern Cross, Dublin 17 in May 2013.
The jurors cleared him of murder but found him guilty of the lesser charge of manslaughter after deliberating for over eight hours.
Just before the jurors returned with their verdict, Dave Mahon walked over to his wife Audrey, gave her a bank card and squeezed her hand.
He then took his seat in the dock and moments later, he became the convicted killer of her son Dean Fitzpatrick.
With both hands resting on top of his walking stick, the 45-year-old gave very little reaction, staring straight ahead. Audrey wiped a tear from her eye.
Earlier in the trial, Mr Mahon said he did not mean to kill the 23-year-old.
He told gardaí that Dean Fitzpatrick just walked into the knife during an argument on May 25, 2013.
He even suggested he may have wanted to walk into it because of his history of self-harm.
The 45-year-old was remanded in custody and tried to make his way over to Audrey but was stopped by a prison officer and escorted out of the court room.
The court heard more than one victim impact statement may be required for his sentence hearing, to reflect the views of different sides of the Fitzpatrick family.
He is due to be sentenced later this month.
