Seung-Hui Cho, South Korean mass murderer (died 2007)

Seung-Hui Cho was a South Korean mass murderer who perpetrated the Virginia Tech shooting in 2007. Cho killed 32 people and wounded 17 others with two semi-automatic pistols on April 16, 2007, at Virginia Tech in Blacksburg, Virginia. This killing is the deadliest school shooting in U.S. history, and was at the time the deadliest mass shooting in U.S. history. A senior-level undergraduate student of creative writing at the university, Cho died by suicide after police breached the doors of Virginia Tech's Norris Hall which Cho had locked with heavy chains, where most of the shooting had taken place.
