Authorities looking into the Uvalde shooting claimed to have discovered how the shooter entered a building that was supposed to be safe.

The chief police officer in Texas said that a teacher had propped open the outer door.

Within a few days, the assertion made by Col. Steven McCraw, director of the Texas Department of Public Safety, was withdrawn.

Instead, the door had been closed by the teacher, according to DPS officials, but for some reason, it did not lock, even though it was intended to.

Emilia Marin, a school teacher who dealt with children after school, said she still struggles with post-traumatic stress disorder as a result of the massacre and its aftermath her first public statement. She is adamant that everyone knows what did and did not occur on that particular day, according to ABC News.

“I died that day,” Marin said.

Marin said she always wanted to work with children and worked as a speech therapist in the special education department at Robb Elementary and managed after-school programmes.

“Right now, I’m lost. Sometimes I go into a dark place. And it’s hard when I’m there, but I tell myself, you can’t let him ( the gunman) win. You can’t let him win, I’m a fighter. I will be okay. I’m going to learn to live with this, I am suffering mentally, of course, emotionally. I am suffering from post-traumatic arthritis, which is very painful. There are nights when everybody goes to bed and I just stay awake with the pain and my daughter tells me Mom, soak in the tub.’ And I tell her I can’t because I can’t get out,” Marin said.

“I sit there at night, replaying that day in my mind,”

In the closing days before summer break, an 18-year-old shooter who had previously attended the school attacked, killing 19 pupils and two of their teachers. Investigations continue on what motivated him to be assigned on that mission to that school.

Deputy superintendent of police spokesman Travis Considine explained the situation to ABC News: “DPS initially reported that an unnamed teacher at Robb Elementary School used a rock to prop open the door that the shooter used to enter the school. It was later discovered that the same teacher had removed the rock from the doorway prior to the arrival of the shooter and had closed the door without realising it was unlocked.”

“DPS corrected this error in public announcements and testimony and apologizes to the teacher and her family for the additional grief this has caused to an already horrific situation,” DPS Considine added.

Marin stated that she wants the country to know what she did that day when confronted with the worst-case scenario: a man armed with a rifle and untold rounds of ammunition approaching the door of the elementary school where she worked. This was the first time she spoke about the events to anyone other than her family and law enforcement.

“I walked out and then they yelled he had a gun, I ran back in. I ran back to the building and I closed the door, I am telling the operator that he is shooting. I could hear the kids screaming. I could hear the kids screaming. I closed the door. I went in and knocked on the teacher’s door across from me. I was banging, she opened it. She said ‘What is going on?’ I said there is a shooter on campus. There was shooting and it wouldn’t stop. He just kept shooting and shooting, I looked around and I hid under the counter. The whole time I am asking the operator, ‘Where are the cops? Where are the cops?”

“Administration let us down. They failed us. He could have defended me. He knew who ‘the teacher’ was and chose not to,” Marin said. It makes no sense when you have dedicated your life to working for the district,” Marin added.
