In the two weeks since the three Atlanta-area spa shootings claimed the lives of eight people, 20 other mass shootings have taken place across the country, reports CNN. At least seven mass shootings occurred in the week between the attacks in Atlanta and in a grocery store in Boulder, Colorado. In the week that followed, that number more than doubled. Most recently, the Los Angeles Times reports that four people, including a child, were killed Wednesday evening and a fifth person was injured in a mass shooting at an Orange office complex. Few details were immediately available about the victims or a potential motive for the shooting. Officers encountered gunfire when they arrived and opened fire. The shooter was taken to a hospital with a gunshot wound and was listed in critical condition Wednesday night. It was unclear if the wound was self-inflicted or if he was struck by police gunfire. The other wounded person, a woman, was listed in critical condition Wednesday night.
