They track down the killer by following clues from the first two victims: A pregnant schoolgirl whose fetus the killer removed, and a single mother strangled from behind on a bus. They had tried to pump Shin for information, but without success. They stake out the killer's home, but when the killer comes home, he notices the cops and runs. Kang follows him into a nightclub, where the killer slices off a lesbian's ear and then slits her throat, just like Shin's third victim. Kang fires two rounds into his chest; this puts him in a coma. Despite this, the murders still continue. The police capture the next suspect, but the murders keep occurring.
