Although there was never any doubt that Kehoe was the perpetrator, the jury was asked to determine if the school board or its employees were guilty of criminal negligence. After more than a week of testimony, the jury exonerated the school board and its employees. In its verdict, the jury concluded that Kehoe “conducted himself sanely and so concealed his operations that there was no cause to suspect any of his actions; and we further find that the school board, and Frank Smith, janitor of the school building, were not negligent in and about their duties, and were not guilty of any negligence in not discovering Kehoe's plan.”
