What happened
On 1 October 2019, Joel Marin attacked a classroom used by Savo Vocational College inside Kuopio’s Herman shopping centre with a bladed weapon. A 23-year-old Ukrainian woman was killed and several other people were injured. Police arrived within minutes and stopped Marin after shooting him in the leg.
The investigation
The National Bureau of Investigation examined evidence showing substantial advance preparation. A court-ordered mental-health assessment found Marin to have been of sound mind. Prosecutors ultimately brought attempted-murder charges that extended beyond the people physically injured because other people were also targeted during the attack.
What the courts concluded
In November 2020, North Savo District Court found Marin guilty of one murder and 20 attempted murders and sentenced him to life imprisonment. The Eastern Finland Court of Appeal upheld the life sentence in November 2021. Marin’s lawyer later said he would not seek Supreme Court review, so the appellate judgment remained in force.
Why the case remains significant
Unlike Finland’s earlier major school shootings at Jokela and Kauhajoki, the Kuopio perpetrator survived and stood trial. The case therefore produced a detailed judicial record on planning, criminal responsibility and the scope of attempted-murder liability in a mass attack.
