Attleboro school officials are investigating the discovery of what is being described as a “hit list” written by an elementary school student. Superintendent Kenneth Sheehan said he will meet with school staff, police, and other officials to investigate a note containing the names of students that was found at Hill-Roberts Elementary School. Sheehan told The Sun Chronicle that a substitute teacher got the note written by a disabled student a week ago and gave it to a school counselor. Sheehan, who had been on vacation, said he was not told about it until Monday because the staffers did not think the child intended to act on it. Sheehan said he believes the students are safe, but he is taking the note seriously.
