A gunman opened fire inside a building where more than 250 kids and staff were starting a day of summer camp on Monday, setting off a panic that ended with a gunfight with police in Duncanville, Texas.
Officers shot the attacker, who was later declared dead at a local hospital. Authorities are crediting the fast response by camp staff and police with preventing injuries to anyone else.
The assault in the Dallas suburb initially triggered fears of a new tragedy, coming weeks after a mass shooting at a school in Uvalde, Texas. Across the country, there have been 267 mass shootings so far this year, according to the independent Gun Violence Archive.
