He was cleared of the man’s murder but found guilty of his manslaughter.
David Brannock. of St Joseph’s Way, Ballymun, was charged with murdering Jason Flannery; causing serious harm to John O’Neill; and assault causing harm to Mr Flannery’s daughter, Jade Byrne; son, Anthony Byrne; and their mother, Claire Byrne.
He pleaded not guilty to all five offences on September 13, 2012, at St Joseph’s Way, Poppintree, Ballymun.
The Central Criminal Court trial heard that Jade Byrne got into an argument with Brannock during her Junior Cert result celebrations earlier. The argument escalated and other family members became involved.
Brannock was asked to leave the Byrne/Flannery home in Cairn Court, a short walk from his home. Mr O’Neill said the accused shouted: “I’ll be back and yous are all going to get it.”
The family heard banging on a front window later and the men went outside, where they saw the accused running away. Father and son chased him towards St Joseph’s Way, where Brannock stabbed them both.
Mr O’Neill said he followed them, but Brannock struck him too.
Jade Byrne said she followed and found her father lying on the ground. She said she approached the accused and he slashed her.
Claire Byrne said that Brannock pushed her to the ground when she arrived.
Mr Flannery died at the scene from a stab wound to his neck. Two stab wounds to his stomach would have contributed to his death.
A trail of blood led gardaí from Mr Flannery’s body to Brannock’s home, where they found him hiding in the dark behind furniture.
The jury found Brannock guilty of the offences against John O’Neill, Anthony Byrne, and Jade Byrne.
They found Brannock not guilty of murder, but guilty of Mr Flannery’s manslaughter by 10-2 verdict. They cleared him of assault causing harm to Claire Byrne.
Brannock will be sentenced on December 2.
