In short order and independently from Conan, Kogoro realizes that he has become the victim of a carefully arranged deception, with the culprit having disguised himself as his prospective victim to gain an alibi. Conan refrains from interfering directly, limiting himself only to drawing clues to acquiring vital evidence.
OAVs
While Kogoro's intellectual and deductive skills are initially not in hard demand here, he shows true professionalism when his observation turns into a kidnapping and blackmail case, with some support from the Detective Boys.
Movies
Movie 09: Strategy Above the Depths
Because of one of the culprits' striking similarity with his wife Eri, Kogoro works all the harder to prove her innocence, only to discover her true guilt in the matter. He is only temporarily stumped off when he fails to produce a crucial piece of evidence at the time of his first revelation attempt. This is also the first case which he solves without direct promptings from Conan.
Movie 13: The Raven Chaser
By chance, Kogoro is able to deduce the location for the last planned murder from the star constellation of the Big Dipper and Polaris quite independently, if a bit belatedly, from Conan for the joint police commission.
