In Kuopio, Finland, a violent incident unfolded on October 1, 2019, when 25-year-old Joel Marin attacked his classmates at Savo Vocational College. Armed with a sabre, Marin entered a classroom and began striking students, quickly escalating what began as a regular school day into a chaotic scene of terror and confusion. The attack resulted in one death and left ten individuals injured, triggering a swift response from emergency services. The primary victim, a young male student, succumbed to his injuries shortly after the attack began.

Witnesses described a frantic atmosphere as students attempted to escape the classroom while others sought to intervene. The police responded promptly, arriving on the scene within minutes, where they apprehended Marin. Following the attack, law enforcement declared the situation under control, and the injured were transported to various hospitals for treatment. Marin was later charged with manslaughter and attempted murder, leading to considerable discourse on mental health and safety measures in educational institutions.

The wake of the attack led to discussions surrounding gun and weapon control in Finland, as it provoked a national reflection on school safety. Educational institutions were urged to review and enhance their security protocols. Furthermore, Marin's motives became a focal point of investigation, raising questions about mental health issues and the warning signs that may have been overlooked prior to the incident.
