Conan and Heiji interrogate the three suspects to learn that they respectively attended a sumo match, a volleyball game, and a soccer game. Conan and Heiji deduce that Teruaki attended a baseball game and that one of the suspects must have also attended the same game. Conan and Heiji realize that the soccer game fan, Takuya Kyuma, had been using baseball terms to describe a soccer game meaning he is the culprit.
