On the morning of the attack at approximately 9:00, Marin arrived on a bicycle to a post office adjacent to a supermarket. He entered the supermarket first and purchased several items: a 2
kg grain-fed pork neck, scissors, paper clips, an Ultra Red
Monster Energy drink, a
Red Bull, and two
Erdinger beer bottles. After purchasing the items, Marin entered the post office to pick up a
longsword he purchased online. He would leave the post office at 9:17. At his apartment, Marin shredded his bank card and destroyed his computer's hard drive. He also tested his longsword on the pork neck he purchased before leaving it in his fridge. At 12:25, Marin arrived at the Savo Vocational College, located in the premises of the Herman shopping mall. The attack began in a computer lab classroom. At the time of the attack, 18 students and one teacher were in the classroom. Students in the classroom described how Marin arrived to class with a "long bag", took out a longsword and began stabbing people. While downstairs, Marin walked up to a janitor. He pointed an air pistol at the janitor's head with the intention of injuring him. However, the air pistol failed to fire due to an improperly screwed
gas cylinder. Marin went back upstairs, leaving the janitor unharmed. While upstairs, Marin checked his air pistol. The attack ended when a policewoman shot and severely wounded Marin, who was sent to the
Kuopio University Hospital for treatment. The policewoman was accompanied by a policeman who fired a shot at Marin, missing him. Marin approached the policeman and struck his hand, wounding him. The policewoman fired a shot at Marin, hitting him in the groin. Marin collapsed but still tried to attack with his sword. Another police officer arrived and fired a
taser at Marin, shocking him. In the process, the officer also deployed a
police dog to bite Marin's leg. After being tased and bitten, Marin eventually dropped the sword and was given first aid. ==Perpetrator==
