An Australian CEO was stabbed to death at his mansion at the Brisbane suburb of Clayfield Thursday night at the house party that he hosted. A 15-year-old boy was one of the attendees of the party war arrested and charged with murder. 59-year-old Greg Josephson, who co-founded youth clothing company Universal Store with his brother Miceal in 1999, was hosting the gathering of around 30 teenagers at his house. According to reports, Josephson and the alleged killer got into an altercation at the party and the teen grabbed a household item to stab Josephson. When the Queensland Police arrived at Josephson’s house, the CEO was alive but critically wounded. He was later pronounced dead at the scene. The alleged killer was captured two blocks south of Josephson’s home. Detectives were working to determine the circumstances of his death, confirming they had located the alleged weapon used, but would not elaborate on other details, local reports claimed. The responding officers described the murder scene as chaotic, the reports added. “It was a confusing situation because it was a party, obviously, and when police turn up at a party it was confusing until obviously all persons present understood what was going on and why police were there,” Detective acting superintendent Craig Williams told Brisbane Times. A triple-zero call had been made to police, Williams said, but whether the call came from inside the home was still being investigated.Josephson founded the Universal Store in 1999 with his brother Michael, with the first store opening in Carindale in Brisbane’s eastern suburbs. The brothers no longer own the company, having sold it for $100 million in 2018. As of December, there were more than 80 Universal Store shopfronts across Australia.Josephson was most recently the chief executive of Josephson Holdings, and previously held roles at Westfield and Lendlease.
