Senior assassin is a game played by high school seniors across the U.S. It involves hunting down classmates after school and shooting them with water guns. Anakin Zehring was playing the game when he and friends fired at another teenage girl with a water gun. Police say the girl's father retaliated with a real gun. Zehring was shot in the back and now the Kansas teenager is paralyzed. Ruben Contreras is now charged with first-degree attempted murder.
