Topic: Seung Hui Cho

Seung-hui Cho (January 18, 1984 – April 16, 2007) was a senior-level undergraduate student at Virginia Polytechnic Institute and State University who killed 32 people and wounded 25 others in the shooting rampage which has come to be known as the "Virginia Tech massacre". Cho later committed suicide after law enforcement officers breached the doors of the building where the majority of the shooting had taken place.

Born in South Korea, Cho arrived in the United States at the age of 8 with his family. He became a US 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 this diagnosis he began to receive treatment and he continued receiving 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.
