NOTE: Again, a crazed, lone gunman is responsible for a mass shooting. The tragedy occurred on Oct. 1 at Umpquah Community College in Roseburg, Ore. when a student, Chris Harper-Mercer, opened fire, shooting and killing nine people and injuring nine others. Harper-Mercer, who is reported to have suffered from mental health issues, owned 14 guns. This tragedy was the 294th mass shooting – where four or more people are killed or injured by gunfire – thus far in 2015. A significant proportion of those shot or injured in mass shootings are victims of a domestic violence/family violence incident. The toll for women murdered by men usually with a gun in 2013 was more than 1,600, according to new study by the Violence Policy Center.
