Dylan Closter to stand trial for NYE manslaughter of David Cassai David Cassai died after he was allegedly punched on the street at Rye. A TEENAGER who allegedly delivered a fatal blow to 22-year-old David Cassai in a New Year's Eve fracas between two groups at Rye will fight his manslaughter charge before a Supreme Court jury. Dylan Closter, 18, was committed to stand trial on August 15 after a magistrate found there was sufficient evidence following a two-week hearing in the Magistrates Court. It was alleged during the hearing that Mr Closter delivered a fatal roundhouse-style punch, which caused Mr Cassai to fall and strike his head on the pavement. Prosecutor Mark Gibson told the Melbourne Magistrates' Court witnesses claimed Mr Closter said, "This is what we've come here for," as he left Mr Cassai lying on the ground. Mr Closter was also charged with affray in relation to the fight in the early hours of January 31. His friends, Tyrone Russell, 21, and Thomas McCluskey, 25 - both facing charges of affray and intentionally causing injury - were also committed to stand trial. Dylan John Closter has been committed to stand trial. The trio appeared at the Supreme Court today - Mr Russell, of Western Australia, via video link. Mr Russell was charged with affray and two counts of intentionally causing injury. Mr McCluskey, of Kilsyth, was also charged with intentionally causing injury and two counts of affray. The court heard there would be just under 100 witnesses called, many of them young people, which could pose problems later in the year due to the timing of VCE and university exams. The trial is expected to take between three and four weeks. The court heard the charges could be severed and some may resolve. Mr Closter's counsel Justin Hannebery said the manslaughter charge would certainly go to trial. Mr Closter - a third-year apprentice plumber from Launching Place - previously told the court he was attacked first. The three men charged over the incident are on bail and will appear for a further directions hearing on November 1.
