Students, parents, friends among the dead in El Paso

One man protected his wife and granddaughter before he was fatally shot; another was killed during an outing with his beloved son.

Stories of bravery and loss are emerging from the shootings that took more than 30 lives in El Paso, Texas, and Dayton, Ohio.

A shooter opened fire at a Walmart store in the Texas border city, leaving 22 people dead and some two dozen injured. Hours later, at an entertainment district in Ohio, another gunman killed nine people and injured more than two dozen others.
