In April 1994 in Rwanda, Tutsis were rounded up and herded to Muranzi, where approximately 50,000 were gathered at the Muranzi Technical School and almost all were massacred by Hutus.

 　　Over a two-week period in April 1994, Tutsis were taken to Muranzi, either led there or forcibly transported, with an estimated 50,000 gathered at the Muranzi Technical School. This effectively weakened Tutsi resistance in Muranzi. Hutus who fled to Muranzi were separated to avoid being caught up in the genocide and given a safe place at a private secondary school. Only 34 people survived the Muranzi massacre of 50,000. 

　　After Hutu set fire to Tutsi homes, they fled to the Gikongo church and were then directed to seek refuge at the Muranzi Technical School. On April 21, 1994, Hutu forces surrounded the school and launched a full-scale attack with guns and grenades. The Muranzi Technical School sat atop a hill, open on both sides with no cover. Tutsis hiding in the main building, classrooms, and outside were killed. On April 22, Hutu leaders and French soldiers organized bulldozers to dig mass graves.

　　The bodies of Tutsi victims exhumed in Gikongoro Province in September 1995 were tightly packed, preventing oxygen penetration, and the bodies showed little decomposition. Muranzi is one of six national genocide memorial sites in Rwanda. In the school classrooms, 848 preserved bodies are displayed on wooden tables. Bodies lay on white wooden racks. Actual bodies covered in lime still retained some hair. Uncorrupted bodies were preserved from the mass graves.
