This Is the Deadliest Year for Mass Shootings in U.S. History

Violence erupted at First Baptist Church in Sutherland Springs, Texas Sunday when a gunman opened fire outside the building and then proceeded inside, killing at least 26 people and wounding at least 20 more.

While the casualty count is still preliminary, these figures currently bring the toll of mass shootings in 2017 to 112 deaths, according to the Mother Jones database of massacres, which generally uses the federal definition in defining such incidents.
