The attacker, a teenager, fatally attacked three children at a Taylor Swift-themed lesson on that date. The Southport Inquiry, held at Liverpool Town Hall, heard the family member Dion Rudakubana told a close contact there was a danger of his brother "committing an act potentially fatal." The hearing was informed the brother messaged his contact over the Discord messaging app: "Arguments are scary because of the threat of a fatality." The sibling said his relative resembled the violent character in the picture the Coen brothers film. The inquiry has learned the brother last spoke to his relative in 2023 when the killer tossed a object at him Growing Tensions The hearing learned he was identified with a neuromuscular disorder at the twelve years old which resulted in him needing mobility assistance and his parents providing increased care. In response to Richard Boyle, attorney, if that altered their dynamic he stated: "There was tension that came about." The brother acknowledged his sibling showed bitterness toward this change. He testified the hearing that after the family moved from the Welsh capital to the seaside town his brother's moods worsened and he would have "aggressive episodes." The hearing heard he became "increasingly wary" of his relative, who would strike him often. He testified: "I needed to be careful if I did speak to him because every argument could turn into an altercation." 'Genuine concerns' He testified his brother became increasingly physical after he was removed from Range High School in the local area, in autumn 2019. He left for university in the following period and the two communicated rarely "because he was not familiar with having me around." The hearing was made aware of a note he messaged a acquaintance on the platform in which he mentioned his relative was angered by him having conversations after dark because of the poor insulation in their house. He also told his friend there was a danger of "him taking action that could kill." He wrote: "The fights are terrifying because of the threat of a fatality." The counsel questioned: "You had serious fears that your sibling would murder a member of your family?" The brother responded: "In case matters intensified to that extent." The victims lost their lives in the 29 July 2024 attack The counsel inquired how his mother and father responded to the attacker's violent behaviour. "There was no point to try and punish him," he testified. "Additionally, there was a significant danger in proceeding that way. "We said there was a overall danger to well-being in everyday talk, if you seek to address him... it would not end well." When Mr Boyle asked if his parents had been unable to handle of his sibling, he concurred. When asked about his sibling resembling a persona from the movie the Coen brothers film, Dion said: "I've been told that figure's meant to be a psychopath and that's why I employed that term there." He said the previous encounter he had with his relative was in the summer of 2023. He stated that their parents requested the killer to say goodbye to him as he was going to meet his companions and his sibling tossed a container at him but the exit was secured before it hit. Proceedings ongoing.
