The court heard the killer carried out a “revenge attack” after he and Mr Brogan had previously been involved in a scuffle at a friend’s house and he had made a threat to stab his eventual victim. At a sentencing hearing at Cardiff Crown Court on Friday, Mr Brogan’s daughter Sophie described in a statement how her grandfather had been in serious ill health following the murder of his son. She said: “They say a father is the most important man in a daughter鈥檚 life, which has always been true. He was my biggest support and gave me the kind of confidence that stays with you, to stand up, stand firm and do what鈥檚 right and that鈥檚 why I鈥檓 here today because he鈥檚 given me that strength.鈥 Ms Brogan said her father鈥檚 death had 鈥渓eft a hole in our lives鈥. She said he won鈥檛 be there to walk her sister down the aisle, to meet her brother鈥檚 children or spend time with his nieces and nephews, who 鈥渁dored him and they adored them”. “This has devastated our family, not just emotionally but physically. My grandfather, my dad鈥檚 father and best friend, suffered a stroke shortly before the start of the trial, brought on by stress and grief,” she went on to say. 鈥淕eorgie鈥檚 actions directly impacted on our grandfather鈥檚 health鈥 He鈥檚 heartbroken. He lives with the physical consequences of that heartbreak. 鈥淥ur family has been impacted by this, attending the trial while visiting our grandfather in hospital. 鈥淗e wasn鈥檛 just our dad, he was the centre of our family, the eldest sibling, the one that everyone relied on鈥 If someone needed help, he showed up, that鈥檚 the kind of man he was. 鈥淣ow without him we feel unsafe, broken and lost. The hardest part of all of this is knowing it should never have happened. This wasn鈥檛 an accident, it was a deliberate decision鈥 鈥淚t鈥檚 taken away our sense of peace, our sense of security and we have to live with something no one should ever have to live with. 鈥淎ttending the trial has been painful, hearing the trial, seeing the evidence and having to sit near to the person responsible. “Our dad mattered, he was loved, the truth needed to be seen and heard. Nothing we can say can bring him back. 鈥淗e was a son, brother, uncle and friend. To lose him like this was unbearable. It wasn鈥檛 a moment that got out of hand or a misunderstanding, it was a conscious choice to end his life and destroy so many lives in the process. 鈥淐arrying a knife is not harmless, it causes risk, brings pain and ends lives. 鈥淒ad鈥檚 death must stand as a reminder there are consequences for this. Anything else sends out the message this kind of behaviour is excusable. 鈥淚t isn鈥檛 and we will carry this pain for the rest of our lives.鈥
