Kogoro has the police gather the suspects and declares Takehiko to be the culprit. He reveals that Takehiko placed his toy cars under the bed legs allowing the bed to easily slide. They evidence it with Takehiko's statement, when he said that James Dean's car was a Porsche 911, but in reality it was a Porsche 550; revealing he used the 550 in the crime. Takehiko asks how would he know Eri was going to take a shower. Eri reveals that Takehiko filled her fridge with only carbonated drink and Takehiko knew that Alcohol would make one thirsty. As evidence, the murder weapon, the ashtray in Takehiko's room, should contain Akiho's blood. Takehiko confesses and reveals that Akiho threatened to kill him to inherit his money.

Later, Kogoro gives Eri her present, announcing it is her birthday. However, Eri reveals that her birthday was yesterday, and that Kogoro assumed Health and Sports Day was the same day as her birthday. Conan explains that Heatlh and Sports Day used to be on every October 10th, but was changed to the second Monday of October at some point. Kogoro is disappointed his plan of lowering Eri's expectation and surprising her with her present has failed, but Eri happily accepts her gift and kisses him. The next day, Eri angrily phones asking why she received prayer beads and if Kogoro wanted her dead. Kogoro then notices that the real present was in his desk.
