Episode 154: Sonoko's Dangerous Summer Story (Part 2)
Scenario: After talking with Tadahiko, Sonoko falls asleep in the car, and someone puts it in drive. Conan and Ran rescue her from going off the cliff. Later, they encounter Terabayashi who chases them in the woods where they split up, but he is revealed to be a detective working on the serial murder case. Conan goes with Ran, and Sonoko goes with Tadahiko. When Sonoko discovers a bite mark on Tadahiko, he reveals himself to be the serial killer which, at the same time, Terabayashi reveals that Tadahiko has already murdered four other women; Sonoko bit his leg, not his arm as she initially thought. Tadahiko's girlfriend dumped him, who also had brown hair, resulting in him killing brown-haired girls. He attempted to murder Sonoko by shifting the hand brake and putting ice under the wheel of his car. When the ice melts, the car moves in the direction of the cliff. False evidence is placed to fool people that someone broke in his car. Tadahiko fell under the impression that Sonoko took a picture while he killed his latest victim near the railroad tracks, which is where the lights came from, and planned to show Shinichi. Makoto suddenly appears and defeats Tadahiko who is arrested. Ran remembers that he was at a karate competition, who was known as The Prince of Attack.
While they walk to the police station, Sonoko says that she does have one picture left, which is the one she wants to show Shinichi. Conan realizes that culprit still thinks that Sonoko has an incriminating picture and has sent the car over the cliff to destroy it along with the luggage. But he's still confused as to why the culprit thinks such a picture exist.
