Instead of pursuing any further criminal action, prosecutors have secured an agreement where the Boardman teacher's aide -- who's accused of stapling a note to an autistic child's hair -- will immediately resign.

The Mahoning County Prosecutor's Office made the announcement Friday in a news release. 

According to the release, prosecutors and police concluded their review of more evidence obtained in the matter. 

"While the evidence uncovered an egregious act of stapling a note to the child's hair, the evidence does not support a criminal assault charge against the teacher's aide," the release from the prosecutor's office stated. "Under Ohio law, to prove misdemeanor assault, the state must show beyond a reasonable doubt that the teacher's aide knowingly caused or attempted to cause physical harm to the child."

The release goes on to state that all indications from the initial investigation -- along with medical and other evidence recently obtained in this case -- confirmed that no puncture wounds were present on the child's neck, leaving the state without sufficient evidence that the teacher's aide knowingly caused or attempted to cause physical harm to the child.

"While photographs and medical evidence confirmed the presence of an abrasion on the nape of the child's neck, evidence does not link that injury to the conduct of the teacher's aide," prosecutors stated. 

The incident at Boardman Center Intermediate School on Jan. 19 involved a teacher's aide of over 20 years and an autistic student. 

According to a redacted police report, the incident was centered around the student's daily routine of bringing a water bottle to school.

The police report stated, in part, the following: "His teacher and teacher's aid had requested several times that the student brings his own water bottle from home to school... [The teacher's aid] then grabbed a stapler and stapled a note to his hair advising that he is to bring his own water bottle to class..."
