第 1149 集: 少年偵探團與領袖 第二部分 解開葡萄柚汁謀殺謎團
Sango concludes that since no one can verify their alibis, any of the suspects could be the murder, with Menda countering that if either her or Kayaki is the one to strangle Usui, this would have woken up Kooriyama. Conan then asks Menda about the medicine her grandma is currently using, she answers high blood pressure medication named Nifedipine, then he asks about Kooriyama juice he drank before falling asleep, in which he replies grapefruit juice. Then Conan and Haibara state that the reason he fell asleep was because he consumed the juice along with Nifedipine put in the straw of each grapefruit juice by someone, but normal customers were fine because the juice was put in an iced plastic cup which gave them the bigger straw. Kooriyama also mentions that Usui felt a strange taste from the juice he consumed as well and accuses Menda for murdering Usui, with her countering that she had lost her medicine, implying that the murderer is either him or Kayaki. Meanwhile, Rumi expresses her surprise toward Haibara’s knowledge about medicine, with Conan mentioning that Professor Agasa taught her that. Tsukumo reports to Sango that the towel used to wrap around the victim was the one used in the hut seats where the Detective Boys confirm to have sat in, but suddenly, Genta’s swimsuit rips at one of the shoulders, making Ayumi associate this with ancient Roman. And speaking of ancient Roman, Conan recalls something he had watched before. Forensic report shows that Kooriyama is most likely the culprit because they found his fingerprints and palm prints in the edges of the towel. At first, Kooriyama denies as he would never do such a thing but Sango continues as there were also trace of Usui’s resistance between the two edges where they found the said prints, then he concludes that Kooriyama hadn’t consumed neither Nifedipine nor the grapefruit juice. But Conan points out that Sango is probably wrong because no one would sleep in the room where they just kill a person besides the fact that all straws of each grapefruit juice have been thrown away. From there, Conan and the others help point out the culprit, but why is Kooriyama making a call privately? (Source: DCW Wiki)
