Seung-Hui Cho

Seung-Hui Cho (/sʌŋ hiː tʃoʊ/; January 18, 1984 – April 16, 2007) was a South Korean mass murderer who killed 32 people and wounded 17 others on April 16, 2007, at the Virginia Polytechnic Institute and State University in Blacksburg, Virginia. An additional six people were injured jumping from windows to escape. He was a senior-level undergraduate student at the university. The shooting rampage came to be known as the Virginia Tech shooting. Cho committed suicide after police breached the doors of the building where the majority of the shooting had taken place. His body is buried in Fairfax, Virginia.

Born in South Korea, Cho arrived in the United States at the age of eight with his family. He became a U.S. permanent resident as a South Korean national. In middle school, he was diagnosed with a severe anxiety disorder known as selective mutism, as well as major depressive disorder. After his diagnosis, he began receiving treatment and continued to receive therapy and special education support until his junior year of high school. During Cho's last two years at Virginia Tech, several instances of his abnormal behavior, as well as plays and other writings he submitted containing references to violence, caused concern among teachers and classmates.
