Detective Conan

Realizing only the wonder left is the dragon fire, the film crew decide to let Kogoro investigate in order to stop Shinroku before he attacks them again. As they learn more about Shinroku, the director is stabbed with a dragon designed dagger and hospitalized as a result. That night at the hotel, the culprit attempts to sneak into a room and attack someone but is ambushed by the crew and police. They reveal they moved that person away and declare the culprit to be Yuuichi Kitamura. Conan tranquilizes Kogoro and reveals Kitamura was the cause of Yayoi's parent's deaths as he had been hiking in a dangerous area and a button of his was found by Shinroku. Shinroku realized who the button belonged to two weeks prior when he saw a picture of the old crew and investigated Kitamura in Tokyo. When Shinroku met with Kitamura in Hiroshima, Kitamura drugged him with sleeping pills and disguised him as himself to establish an alibi.
