Question: How many people were killed by the mass murdered that killed Kevin Granata?

<P0-S0> Kevin P. Granata (December 29, 1961 – April 16, 2007) was an American professor in multiple departments including the Departments of Engineering, Science and Mechanics (in which he was tenured) and Mechanical Engineering at Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, Virginia. <P0-S1>  Granata held an additional academic appointment as a professor in the Virginia Tech-Wake Forest School of Biomedical Engineering and was an adjunct professor at the University of Virginia in the Department of Orthopedic Surgery. <P0-S2>  During the Virginia Tech shooting, he shepherded students into his office in order to safeguard them. <P0-S3>  He was then killed by Seung-Hui Cho after he went to investigate and intervene. <SEP> <P1-S0> Seung-Hui Cho (in Korean, properly Cho Seung-Hui; January 18, 1984 – April 16, 2007) was a South Korean spree killer and mass murderer who killed 32 people and wounded 17 others armed with two semi-automatic pistols on April 16, 2007, at the Virginia Polytechnic Institute and State University in Blacksburg, Virginia. <P1-S1>  An additional six people were injured jumping from windows to escape. <P1-S2>  He was a senior-level undergraduate student at the university. <P1-S3>  The shooting rampage came to be known as the Virginia Tech shooting. <P1-S4>  Cho committed suicide after police breached the doors of the building where most of the shooting had taken place. <P1-S5>  His body is buried in Fairfax, Virginia. <SEP> <P2-S0> The May 2004 Caribbean floods were a flood event that took place in the Caribbean Islands, mainly Hispaniola and some parts of Northern Puerto Rico from May 18, 2004 to May 25, 2004. <P2-S1> The storm caused significant rainfall, with over 9.7 inches of rain falling at the most in Haiti, and 10 inches falling at the most in the Dominican Republic. <P2-S2>  These floods were caused by over two weeks of persistent rain in the Caribbean area, which eventually caused the landslides that killed many people. <P2-S3>  The floods caused much damage in Haiti and the Dominican Republic, with over 1,300 homes being destroyed and about 2,000 people being killed.Due to this destruction, nearly 15,000 people were displaced with nowhere to live. <P2-S4>  The area that felt the worst of the flooding was the town of Jimani, near the border of Haiti and the Dominican Republic.In fact, the destruction present at Jimani was so bad that Dominican president Hipolito Mejia declared a national day of mourning after seeing the effects of the storm. <SEP> <P3-S0> The Sri Lankan Civil war was very costly, killing over 100,000+ civilians and 50,000+ fighters from both sides of the conflict. <P3-S1>  The "Tamil Centre for Human Rights" recorded that from 1983 to 2004, 47,556 Tamil civilians were murdered by both the Sri Lankan government and IPKF forces. <P3-S2>  Another organization called NESOHR published that from the beginning of the war to the , 4000 to 5000 Tamil civilians were killed in large scale massacres, with a total civilian death of around 40,000. <P3-S3>  Civilian casualties that occurred on 2009 is of major controversy, as there were no organizations to record the events during the final months of the war. <P3-S4>  The Sri Lankan government revealed that 9,000 people were killed in the final months of the war, but it did not differentiate between LTTE cadres and civilians. <P3-S5>  The UN, based on credible witness evidence from aid agencies and civilians evacuated from the "Safe Zone" by sea, estimated that 6,500 civilians were killed and another 14,000 injured between mid-January 2009, when the "Safe Zone" was first declared, and mid-April 2009. <P3-S6>  There are no official casualty figures after this period but estimates of the death toll for the final four months of the civil war (mid-January to mid-May) range from 15,000 to 20,000. <P3-S7>  A US State Department report has suggested that the actual casualty figures were probably much higher than the UN's estimates and that significant numbers of casualties weren't recorded. <P3-S8>  A former UN official has claimed that up to 40,000 civilians may have been killed in the final stages of the civil war. <P3-S9>  Several human rights groups have even claimed that the death toll in the last months of the war could be 70,000. <P3-S10>  The Sri Lankan government has denied all claims of causing mass casualties against Tamils, arguing that it was "taking care not to harm civilians". <P3-S11>  Instead, it has blamed the LTTE for the high casualty numbers, stating that they used the civilians as human shields. <P3-S12>  Both the Sri Lankan government and the LTTE have been accused by the U.N for war crimes during the last phase of the war.
