Muranen, a military conscript, returned to his barracks in Hamina from a holiday on Sunday, 17 April 1994, stole an Rk 62 assault rifle from the barracks and fled to his hometown Kotka. The next day, still dressed in his uniform, he entered his neighborhood and fatally shot two of his neighbors, Reino Vulkko, 53, and his wife Sirkka, 54, with a crossbow he had taken from his home. On 19 April, he fatally shot a postman, Matti Olli, aged 45, with the assault rifle. He also shot randomly at nearby houses, escaping into the forest with his dog. During the chase, police shot the dog with a submachine gun, while Muranen returned fire with the assault rifle. The police chased him for a day before slightly wounding him. After he was arrested he expressed regret that his military service would be terminated. Muranen was found to be competent to stand trial. Kotka district court sentenced him to life in prison on three counts of murder, eight counts of attempted murder, and three counts of attempted manslaughter. He was sent to a prison in Mikkeli.
