Only a small portion of the leaked security video is shown in the previous report featured at the top of this story.
State Rep. Joe Moody identified the officer standing on the right side of the hallway in the video as Uvalde CISD Officer Ruben Ruiz.
Ruiz could been seen looking at his phone while officers waited in the hallway.

Many people on social media criticized Ruiz for being distracted.
As it turns out, Ruiz was on the phone with his wife Eva Mireles, according to Moody.
She had called her husband from inside the classroom, saying she had been shot and was dying.
