Adrian Gonzalez was the first law enforcement officer to arrive at Robb Elementary on May 24, 2022, when a gunman was shooting at the school.

Prosecutors alleged Gonzalez hesitated and did not do his duty.

The gunman was able to enter a classroom and kill 19 students and two teachers.

After deliberating for more than seven hours, the Nueces County jury found Gonzalez not guilty in the 29 counts of child endangerment.

This was the first trial over the response to the Uvalde attack.

Former school district police chief Pete Arredondo is also expected to be tried.

Defense attorneys for Adrian Gonzalez asked for a mistrial after a Robb Elementary School teacher testified on Tuesday that she saw a man matching the description of the mass shooter near the area where Gonzalez was.

One issue was her testimony contradicted her interview with the Texas Ranger's

and her new testimony should have been provided to the defense under the prosecution's discovery.

Judge Sid Harrell said this was negligence and not deliberate and wasn't sufficient to call for a new trial with the new jury.

Testimony is expected to continue on Thursday.

Gonzalez is accused of child neglect by not confronting the gunman who killed 19 children and two teachers in 2022.
