Abigail Zwerner, 25, was released from hospital after being shot in the chest in her classroom.
Ms Zwerner was shot by a six year old boy who had a loaded gun with him in class. The boy is said to be suffering from “acute disability”.
According to her lawyer, the Wednesday shooting was “entirely preventable”. It could have been prevented if only the school administrators could have listen to the teachers when they reported that the boy had a gun.
The board members convened a meeting on the same day after the incident and decided that the superintendent of the school should be fired, which they did.
Police have not announced any charges.
The shooting – which authorities have described as “intentional” – raised questions about what legal consequences may follow and for whom.
“On that day, over the course of a few hours, three different times school administration was warned by concerned teachers and employees that the boy had a gun on him at school and was threatening people,” said attorney Diane Toscano.
“But the administration could not be bothered.”
According to Ms Toscano, a teacher at Richneck Elementary School told an official she believed the young boy had put the gun in his pocket before he went out for break.
The official allegedly responded: “Well, he has little pockets.”
Another administrator ignored a teacher’s request to search the boy and his backpack, Ms Toscano said.
Later on Wednesday, the school board convened to sack the district superintendent, Mr Parker. The assistant principal of the School also resigned from that position that same day.
The superintendent’s salary was over $250,000 (£200,000) per year and he will continue to receive full salary and benefits until next year June because he was fired without cause.
Last week, the family of the young boy said he suffered from an “acute disability” and rarely attended school without one of his parents being present. The day of the shooting he had attended school alone.
The family also praised Ms Zwerner for supporting them to get the best education and learning environment for their child.
Ms Zwerner saved lives on the day of the shooting by ushering her students out of the class after being shot through the hand and in the chest.
Police also said the gun used by the boy had been legally purchased by his mother. The boy’s family said the weapon had been “secured”.
The law prohibits anyone from leaving a loaded, unsecured firearm recklessly in a manner that may endanger a child under the age of 14 years.
