MOORE, Oklahoma - A Moore elementary teacher is under investigation for an incident involving an elementary school student, and the 6-year-old's parents said they're scared to take their son back to school.

Since it is an open investigation, the district has not released much, but the student's parents said the teacher hit their child and needs to be permanently removed from the classroom.

Nathan is a 6-year-old who quickly makes any cellphone he finds play his favorite songs. Music is a key form of communication for Nathan who is unable to speak due to developmental delays from his epilepsy.

“He's non-verbal. He doesn't speak at all,” his mother Stacey Felix said.

His parents believe that limitation is what kept Nathan from telling them what happened earlier this month in his special education class at Fisher Elementary. Instead, they learned of the alleged incident from the school's principal.

“One of the teachers in the room reported that the primary teacher struck him on the head with a baking pan or cookie sheet. Nathan reached for something that didn't belong to him and she just popped him on the head with it,” she said.

Both Nathan and the teacher in question are no longer at school.

The district released the following statement: "The teacher is currently on administrative leave pending the outcome of the investigation regarding an incident that happened in the classroom."

“You just kind of  entrust your child with somebody that you don't know and you hope for the best. Once that trust is broken it's over with. You cannot go back,” said Alex Smith, Nathan’s father.

Nathan's parents are now scrambling to find their son another special education program, but building their trust for a new teacher will take some time.

“This is like the worst nightmare we've talked about this before. We just never thought that it would be this way with a teacher that gets so much training,” Felix said.

Pending the outcome of the investigation, the parents said they would consider pressing charges against the teacher.
