A brother and sister have described the moment their father was killed during a confrontation following her Junior Cert result celebrations.
They were giving evidence in the trial of a Dublin man charged with murdering the father of three, and injuring them, their mother and their uncle.
David Brannock of St Joseph's Way, Ballymun is charged with murdering Jason Flannery, causing serious harm to John O'Neill and assault causing harm to Jade Byrne, Anthony Byrne and Claire Byrne on September 13, 2012.
Mr Brannock (23) has pleaded not guilty to all five offences and went on trial yesterday at the Central Criminal Court.
Prosecuting barrister Dominic McGinn told the jury that all five offences arose from a violent confrontation in the early hours at St Joseph's Way, Poppintree, Ballymun.
Jade Byrne told the court she was 16 at the time and had argued with the accused in her friend's house while celebrating her Junior Cert results. She returned home, and the accused arrived there later. He was asked to leave.
They heard a banging on the window and her father and brother went outside and saw the accused running away and followed him. She said her brother was stabbed. "My Da ran in at him then, when he saw my brother's head was stabbed. That's when he stabbed my Da."
The trial continues.
