Matti Juhani Saari, 22, posted a video on YouTube in which he fired an automatic pistol into the ground and warned viewers ‘You will die next.’ The police became aware of the video and detained Saari on Monday. He was allowed to walk free not long after while still retaining a gun permit and his weapon.
The following day Saari went to the Kauhajoki School of Hospitality where he was a student chef and carried out his threat. He killed nine people before turning the gun on himself. He later died in hospital along with a tenth victim of his attack.
According to suicide notes left behind, Saari said that he ‘hated mankind.’
According to the many witnesses of the massacre, Saari walked the corridors dressed in black and a ski mask firing at all and sundry.
