Former Uvalde school police officer Adrian Gonzales is on trial for 29 counts of child endangerment related to the 2022 Robb Elementary shooting. Prosecutors allege Gonzales failed to engage or delay the gunman, remaining outside while the attack unfolded. His defense argues the scene was chaotic, he lacked clear information on the shooter's location, and he assisted in evacuations. The trial, moved from Uvalde due to fairness concerns, began with opening statements detailing conflicting accounts of Gonzales' actions and the overall police response.
