UNDATED (AP) — The weekend shooting massacre that killed 22 people in El Paso, Texas, happened in a city that’s sometimes called the “Ellis Island” of the border. Many Mexican Americans in Los Angeles, New Mexico, Texas, Colorado and beyond can trace their families’ roots to El Paso. The white gunman is believed to have written an anti-Hispanic rant before opening fire with an AK-47 on Walmart shoppers. Many of the victims were Latino.
