On February 2, 2024, the Otsu District Court sentenced 36-year-old Kohei Iizuka to life imprisonment for the murder of his probation officer, Hiroshi Shinjo, during a probation meeting. At the time of the incident, Iizuka was under a suspended sentence for a robbery case and had been receiving probationary supervision. During the trial, Iizuka acknowledged the charges, stating he acted upon the voice of a guardian deity, which raised questions about his mental capacity at the time of the crime. The court had to weigh the aspects of Iizuka's responsibility against his claim of diminished capacity, a key point of contention throughout the trial.
