Case Closed: The Worst Birthday (2)

SYNOPSIS

That night, Conan realizes how the murder was done and who the culprit is. The next day, he drops a hint for Kogoro by spilling ketchup on a food cart which creates an evenly spaced ketchup stain on the floor, miming the victim's blood stain. 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.
