Uvalde Shooter Fired Outside School for 12 Minutes Before Entering

UVALDE, Texas—Local residents voiced anger Thursday about the time it took to end the mass shooting at an elementary school here, as police laid out a fresh timeline that showed the gunman entered the building unobstructed after lingering outside for 12 minutes firing shots.

Victor Escalon, a regional director for the Texas Department of Public Safety, gave a new timeline of how the now-deceased gunman, 18-year-old Salvador Ramos, walked into Robb Elementary School, barricaded himself in a classroom and killed 19 children and two teachers.
