Edwards also said that Gabriel's behavior at home didn't make them think he was acting up at school.
"He's not perfect, but he's not out of control," Edwards said.
After hearing the tape, Edwards and McMahan pulled Gabriel out of school and are trying to figure out which school to send him to next year.
They are also exploring the possibility of pursuing a civil or criminal action against Woodward and the school district.
But Edwards said they are most concerned about the psychological impact the entire situation has had on Gabriel.
"I hope this doesn't affect him long-term, in his feelings about school or teachers," Edwards said. "We're going to seek some kind of help for him."
