Officer Frank is a mostly french but also english man who was the kidnapper of Giulia Mandolesi's son Dave. He is now formerly a Canadian cop and is sentenced to fifty years in jail because of what he did to Dave Mandolesi. There isn't much said about him but he could possibly been a spy for Sheral, Giulia's sister who is a criminal mastermind because he only attacked Dave and no one else at the school. Sheral could of sent him to kill Dave. Who knows? It's up to you to figure this one out.
