The sisters of a barbershop assassin laughed in court as they watched their bloodied brother swear while talking about the stabbing murder with police. Alfredo Isho was seated and gowned at Classico Hair Studio in Bossley Park, in Sydney's west, on January 11 2019, when Fredon Laith Botrus burst through the door. Having circled the block on a motorbike four times to identify his target, the then 18-year-old was still wearing a helmet when he fatally punctured his victim's artery and right lung. The trial in the NSW Supreme Court ended in a 20-year jail sentence on Tuesday, but on Wednesday it was revealed the killer's sisters Valnten and Valy Botrus could not stop laughing in court as a video of their bloodied brother played.
