People walk with flowers to honor the victims in Tuesday's shooting at Robb Elementary School in Uvalde, Texas, Wednesday, May 25, 2022. Desperation turned to heart-wrenching sorrow for families of grade schoolers killed after an 18-year-old gunman barricaded himself in their Texas classroom and began shooting, killing at least 19 fourth-graders and their two teachers.
