What happened Mr. Fillion was working at his desk when he heard a

terrible commotion coming from another office. He rushed out and saw a shadowy shape running down the hallway. Unable to apprehend the shadowy figure, he turned to investigate the cause of the noise he had heard. He turned his attention to the office area and there, on the floor, was the remains of the filing cabinet containing all the student files for all the students in the school!

After carefully going through all the remaining files and comparing them to the list of students in the school, six files were found to be missing. These people became the prime suspects.
