Virginia Tech shooting: Seung-Hui Cho guns down 32 people and injures 17 before committing suicide.

The 2007 Virginia Tech shooting was one of the deadliest mass shootings in U.S. history, occurring on April 16, 2007, in Blacksburg, Virginia. A student named Seung-Hui Cho, a 23-year-old senior at the university, carried out the attack in two separate incidents on campus, first at a dormitory and later inside a classroom building. Armed with two semi-automatic pistols, Cho killed 32 people and injured 17 others before taking his own life. The massacre exposed serious gaps in campus security and mental health intervention systems, as Cho had previously exhibited disturbing behavior and was known to campus authorities. In the aftermath, the tragedy sparked nationwide debates about gun control, mental health services, and emergency response protocols on college campuses. Virginia Tech has since made extensive changes to improve campus safety and crisis management procedures.
