Former teachers at Robb Elementary School, who were victims of the Uvalde school shooting, are testifying at the trial of a police officer accused of botching the response.
Elsa Avila broke down crying, describing how she was shot by the gunman. Uvalde Police Officer Adrian Gonzales faces 29 counts of child endangerment. The state alleges that he knew where the shooter was but failed to act to stop or distract him.
