@BillRM,

, The Virginia Tech massacre was a school shooting that took place on April 16, 2007, on the campus of Virginia Polytechnic Institute and State University in Blacksburg, Virginia, United States. Seung-Hui Cho shot and
killed 32 people and wounded 17 others[1] in two separate attacks, approximately two hours apart, before committing suicide. (Another 6 people were injured escaping from classroom windows.) The massacre is the deadliest shooting incident by a single gunman in U.S. history and one of the deadliest in the world.[2] It was also the worst act of mass murder on college students since Syracuse University lost 36 students in the bombing of Pan Am Flight 103.[3] It is also the second-deadliest act of mass murder at a school campus, behind the Bath School bombing of 1927.
Cho used two firearms during the attacks: a .22-caliber Walther P22 semi-automatic handgun and a 9 mm semi-automatic Glock 19 handgun.[12] The shootings occurred in separate incidents, with the first at West Ambler Johnston Hall, during which Cho killed two pupils, and the second at Norris Hall, where the other 31 deaths, including that of Cho himself, as well as all the nonlethal injuries, occurred.
