Eighteen children and three adults were killed in a shooting at Robb Elementary, Texas Sen. Roland Gutierrez (D) said Tuesday on CNN. He said he learned of the higher death toll from a briefing with the Texas Rangers.

Salvador Ramos, an 18-year-old Uvalde resident, “shot and killed — horrifically, incomprehensibly” more than a dozen children and a teacher, Gov. Greg Abbott (R) said earlier Tuesday. Ramos is also dead, the governor said, apparently killed by officers at the scene. Two people familiar with the investigation said the initial evidence indicates the gunman bought the weapons used in the attack shortly after his recent 18th birthday.

Clint Smith reacted on Twitter:

These are elementary school children who woke up this morning. Who ate their favorite cereal. Who tied their shoes in double knots. Who laughed with friends on the bus. Now more than a dozen are dead. This isn’t normal. It doesn’t have to be this way. It can’t keep being this way.

Sitting outside of my children’s school watching little kids chase one other on the playground and thinking of how this could be any school in this country, at any time. How this has happened before and surely will again. But it doesn’t have to, it doesn’t have to be inevitable.
