Two mass shootings in less than 24 hours left at least twenty-nine people dead in the United States Sunday. The shootings happened in El Paso, a Texas city along the Mexico border and Dayton, a city in the state of Ohio 2500 kilometers northeast. At about 10:40 a.m. Saturday morning, officials said, a gunman walked into a Walmart store in El Paso, Texas and began shooting. Hundreds of people were in the store. Many were buying back-to-school clothes and supplies for their children. Police said twenty people were killed and 26 were wounded in the violence. Among those killed was Jordan Anchondo who died while trying to protect her 2-month-old son from bullets. Police arrested the shooting suspect at the attack site. He is identified as Patrick Crusius, a 21-year-old man from Allen, Texas, a city about 10 hours from El Paso. Officials are investigating whether he is connected to an online document denouncing the Hispanic population in the U.S. and immigrants, generally.
