The culprit is Yoshihiko Kido. Yoshihiko and Makoto were smuggling clinical drugs out of their universities laboratories and selling them by the dozen. The former, however, didn't want to make that fraud anymore, so he killed the latter. Mitsue angrily slaps him and breaks down, while Kogoro and the police scold him.
