The investigative committee found law enforcement's response to the massacre involved little coordination and no leadership. School faculty, meanwhile, failed to uphold existing safeguards.

Texas state Sen. Roland Gutierrez and Uvalde Mayor Don McLaughlin say they've received complaints about the Uvalde Together Resiliency Center.

The school will be demolished so "students and staff will not have to return to the building at the site of the tragedy," the district said.

"The children!" cries Linda Martinez, a retired pastor who came to the scene with a bouquet of flowers. "So young. I just can't believe it's real. We just have to help each other."

A father whose fourth-grade daughter was killed in the attack, said he raced to the school and raised the idea of charging into the school with several other bystanders.
