A former Texas cop is on trial for his response to the Uvalde school shooting. A teacher at Robb Elementary testified Wednesday that she was pleading with Officer Adrian Gonzales to stop the gunman.

Melody Flores told the jury that the gunman was firing into classroom windows. But Officer Gonzales, she says, did not take action. A total of 19-students and two teachers were killed in the attack. Gonzales faces 29 counts of child endangerment.
