The trial for the murder of Hiroshi Shinjou, a probation officer in Otsu City, begins today, involving the accused, 36-year-old Kohei Iizuka, who faces charges of murder and obstruction of justice. Iizuka is alleged to have attacked Shinjou, 60, with a knife and axe during a meeting at Shinjou's residence on May 24, 2024. The investigation into Iizuka's motives and mental state is central to the case, as he denied the charges during his arrest by Shiga Prefectural Police, claiming, 'I didn't do it, and I don't want to answer anything.'
