Timeline of Texas mass shootings over the years

All eyes are on Texas after a gunman opened fire at an elementary school in Uvalde. The mass violence, which resulted in the deaths of at least 19 children, is now the deadliest school shooting in Texas history.

The state has seen several mass shootings since 1966, when a college student shot down at people from the University of Texas campus tower.

While there is no concrete definition of "mass shooting," most researchers define it as four or more victims killed in a public place. Domestic violence cases at home and gang-related violence are not included.
