The massacre began at Wirjo's home, where he attacked his adoptive son Renny and his friend Arbaiyah, both 4-years-old, with a parang and a sickle. While Renny managed to escape, Arbaiyah was hit in the neck and died. Wirjo then entered the home of Maskur, a neighbour, where he first killed Mrs Maskur with the sickle, before turning on her 80-year-old husband, who tried to help her. Afterwards he made his way through the village, assaulting people at random. Then the people from the village tried to find Wirjo but failed, only to be greeted by a lot of dead bodies spreading across the field. By the end of the day Wirjo had hacked a total of 32 people, most of them farmers on the way to their fields and students going to school. 18 of his victims died at the scene, while two others later succumbed to their wounds in hospital. As the culprit was nowhere to be found authorities temporarily suspended classes at local schools, while people locked themselves in their homes. After an extensive manhunt, including police, dogs, and the army, Wirjo was found the next day just 3 miles west of his house, dangling from the roots of a tree growing over a riverbank. He had committed suicide by hanging himself with his belt.
