She Taught Him

Mercedes Salas was watching Zootopia with her 16 fourth-graders when she heard the first gunshot.

It was supposed to be a celebration day. Awards ceremony in the morning. Snow cones in the afternoon. End of the school year. The kids were sprawled on pillows, lights off, waiting for summer to start.

Then she heard it. Distant at first. Then closer. One of her students looked at her with panic in his eyes and mouthed the word: gunshot. She nodded. Didn't say anything out loud. Didn't want to scare the others.

She started gathering them. Running through her mental checklist. Lights already off. Get kids hidden. Check the door.

She stepped outside her classroom to physically verify her door was locked. Slammed it. Wiggled the handle. One student tried to follow her because he always helped during drills. She told him: "Not today. It's different today."

Then she heard gunshots in the hallway.

She texted her family: "Gunshots in the hallway. Pray for us."

She got on her knees. Positioned three chairs she could throw at an intruder. One of her students silently held up a pair of scissors. She didn't tell him to put them away. The scissors made him feel safe.

Then she heard pounding on her door. Her door knob rattling. Someone trying to get in.

She prayed.

Then she heard children screaming. Then gunshots. Then silence.

When police finally broke through her window to evacuate her classroom, she walked back in. An officer yelled at her to leave. She said: "You need to wait. I have to make sure none of my kids are in there." She walked to the middle of her room. Looked around. Looked again. Then she said: "Okay, I'm ready to go."

She walked back in twice. Because a terrified child might have stayed frozen. Because that's who she is.

Defense attorney Jason Goss asked her what she felt when the glass broke and she knew police had come.

"Relief," she said. "Someone was finally there to help us."

He asked if she had thought she was going to die.

"I did. I made peace with God."

The Revelation

Then Goss asked about her first year at Robb Elementary. 2014. Room 111.

The shooter was one of her fourth-grade students.

She taught him. She recognized him. And eight years later, she heard him killing children in the same classroom where he had once been a child himself.

Room 111. The room he knew. The layout he remembered. The place he came back to.

The defense is building something here. Salas's locked door stopped the shooter from entering her room. Her training, her verification that the door was locked, protected her 16 students. The shooter tried her handle and couldn't get in.

The classroom where 21 people died had an unlocked door.

Why was one door locked and the other wasn't? Who is responsible for that? Is that on Adrian Gonzales, the officer being tried for child endangerment? Or is that a systemic security failure that preceded anything Gonzales did or didn't do?

The Father

Before Salas testified, Christopher Salinas took the stand. His son Samuel was nine years old on May 24, 2022. Fourth grade. Room 112. Awards ceremony that morning. Snow cones planned for the afternoon.

Samuel still has shrapnel in his right thigh. He can walk, but he's in constant pain. He puts more weight on his left leg to avoid the agony in his right. Any exercise destroys him for days. He's triggered by popping sounds, slamming doors, loud arguments, violence on TV.

And the color red. Because of what he saw in the classroom.

The prosecutor asked the question that landed hardest: "Is the child you picked up from the hospital on May 24th the same child that was taken to school that day?"

Salinas answered: "No."

What This Means

The prosecution is calling witnesses to establish emotional weight. The families. The survivors. The teachers. They want the jury to feel the horror of what happened in those classrooms.

But the defense is using these same witnesses to build a different case. Mercedes Salas followed her training. She locked her door. She kept 16 kids silent. She survived. The shooter couldn't get into her room because the door was locked.

Room 111's door was not locked.

The shooter knew that room. He had been a student there. He knew the layout, the windows, the doors. Did he choose it because he knew how to get in?

These questions don't exonerate Adrian Gonzales. But they complicate the prosecution's theory that his response is what endangered those children. If locked doors saved lives and unlocked doors cost lives, then the question becomes: who is responsible for unlocked doors?

That's not a question about one officer's split-second decisions. That's a question about school security. About policy. About a system that failed long before the shooting started.

The prosecution wants to put one man on trial. The defense is putting the whole system on trial.

We'll see which story the jury believes.
