On August 18, 1993, around 4:00 p.m., a group of hikers arrived in the Nomatsiguenga Tahuantinsuyo community as part of a coordinated incursion of three hiker columns into eight communities in the Tsiriari valley. The murders were committed with bladed weapons: arrows, machetes and others were hanged with pitas. Twenty-one people were killed, including children, men and women. On Thursday, August 19, the villagers who came down from the mountain gave notice to the Army from the Mazamari base, and on Friday, August 20, they finished burying the dead with the help of four community members who arrived from Mazamari.
