"In the last nine years, Glocks have figured prominently in at least five mass shootings. In 2007, Seung-Hui Cho, a senior at Virginia Tech University, used a Glock 19 and Walther P22 to kill 32 people and wound 17 others in two separate attacks on campus. The Glock 19 is a smaller pistol that is easier to conceal. Three years later, Jared Lee Loughner used a Glock 19 to shoot 20 people in Arizona, gravely wounding US Representative Gabrielle Giffords and killing six others, including a nine-year-old girl. In 2013, Pedro Vargas went on a shooting rampage inside his apartment complex in Hialeah, Florida. With his Glock 17, Vargas murdered six people and held two neighbors hostage during an eight-hour stand-off until a SWAT team stormed the building and killed him. On June 17, 2015, Dylann Roof killed nine people with a .45-caliber Glock pistol at a historic black church in Charleston, South Carolina. Two months later, Vester Lee Flanagan II shot and killed a Roanoke, Virginia, television reporter and a cameraman with a Glock 19 during a live news broadcast."
