UVALDE, Texas (WOAI) -- Former UCISD Police Chief Pete Arredondo and former UCISD officer Adrian Gonzales both appeared in court Monday for a pre-trial discovery hearing.

Arredondo, who many consider to have been the incident commander for the Robb Elementary shooting response, is facing ten counts of child endangerment. Gonzales, one of the first to arrive at the school that day, faces 29 counts.

The hearing only took a few minutes, but emotions came to a head after it concluded.

For most of the family members of Robb Elementary shooting victims and survivors, this was the first time they saw Arredondo face-to-face since the day of the tragedy.

"It kind of takes the wind out of you," Jesse Rizzo said, of seeing Arredondo. His niece Jackie Cazares was killed in the shooting.

Several family members shed tears seeing him.

Phones and cameras were not allowed inside the courtroom.

Arredondo entered and took a seat where a jury would typically be placed, not making eye contact with the rows of parents lining the courtroom's left side.

Gonzales entered later, sitting in a corner of the room behind his attorneys, back to the families.

Judge Sid Harle did not take action on a motion from Arredondo's attorney, Paul Looney, to toss his client's indictment.

He's not being charged with avoiding his responsibility. He's being charged with a crime that doesn't exist in Texas. He wasn't the commanding officer on the scene. He responded to that situation as a police officer. He was a first responder," Looney said previously.

When Harle brought up the motion, Looney said he wasn't prepared to argue it because he had not had enough time to go over the District Attorney's response. He says that came in on Thursday.

Judge Harle set another pre-trial hearing for Dec. 19, hoping to give all sides enough time to go through mountains of evidence.

The District Attorney's Office gave the co-defendants hard drives, saying there is a 3,500-page report included, and other evidence is still coming in. That includes the recently discovered body camera video from the Uvalde Police Department. Attorneys say they expect to see that and make decisions "quickly."

Looney called looking through all these documents a "monumental task" in court.

Nico LaHood, who represents Gonzales, told WOAI outside the building that he agreed.

"It's a voluminous case," LaHood said. "There's a lot of evidence. We've been told the report is 3500 pages, just the report alone, not to mention the other evidence."

LaHood went on to cite other investigations that did not name his client or find culpability.

One of the big sticking points was the recent Customs and Border Protection report about the Robb Elementary shooting, which came out last week. The District Attorney's Office and Looney both said they had not been able to get unredacted versions of that report, even though some of the CBP agents were witnesses.

The DA's Office told Judge Harle they made it clear to CBP that their employees were not being targeted as part of the investigation, but indicted CBP was not cooperating.

When the court went into recess, DA Busbee went to the rows of families and asked if they had any questions.

Ruben Torres, whose daughter Khloie survived the shooting in Room 112, was escorted out of the courtroom after a short dispute with the DA.

People that should be representing these children, which is our local DA and the state, they're still obviously waiting for reports or they waited for this federal report that came out last week from the Border Patrol, so that's gonna prolong things," Torres told us shortly after he left the building. "Right now they're telling us... limiting our family members on how many can go in there and represent each child that's going in there... They're bullying the family members who have already gone through enough.

Several family members told Busbee there wasn't enough room in this courtroom for all the families to be present, and some had to wait outside because of space concerns.

Arredondo walked over to Gonzales after the hearing and hugged him, talking quietly with him and another man near Gonzales' attorneys.

Family members yelled to the two men as they exited the courtroom.

Gonzales sat in the backseat of a vehicle with his attorneys, covering his eyes as parents like Veronica Luevanos, whose daughter Jailah Silguero was killed on May 24, showed him images of their children on their shirts.

"Coward," some yelled as Gonzales' attorney opened the door.
