WATCH LIVE: Uvalde school shooting trial of Adrian Gonzales

CORPUS CHRISTI, Texas - Former Uvalde CISD officer Adrian Gonzales is set to appear in court again Friday as witness testimony continues.

Gonzales is charged with 29 counts of abandoning or endangering a child. Prosecutors say he didn't act quickly enough during the 2022 massacre, where 19 students and two teachers were killed.

Thursday, the court was forced to go to recess at 2 p.m. after a juror was faced with an unexpected family emergency. That juror is expected to return at 8:30 a.m. Friday to tell the judge whether he'll be able to continue to sit on the panel as the trial continues. If not, the judge will appoint an alternate juror to continue proceedings.

The testimony of a retired Uvalde PD officer is expected to pick up at 9 a.m. FOX Local will stream the trial proceedings at this page.
