পর্ব 173: রক্তাক্ত চিহ্নগুলো খুনির দিকে নিয়ে যায়, যে একটি মুদ্রা ব্যবহার করে আতশবাজির মতো ভান করে এবং একটি বিশেষ বিমানবন্দরের কোড ব্যবহার করে।

173

Bloody marks are discovered at and near the crime scene. Conan puts Kogoro to sleep to reveal that the culprit imitated the fireworks noise by blowing into a 5 yen coin, making people believe the fireworks started early. The killer is revealed to be Izumi Sano and the "S" is not the real code, but the "K.I.X." was. Chihiro was killed instantly as she was shot through her heart. K.I.X is the special code for Kansai Int'l Airport, located in Izumisano, Japan. She wrote the "S" on the wall after killing Chihiro with her own shotgun, using reverse psychology as the basis of her methods. As evidence, the blades of Izumi's skates have traces of Chihiro's blood on them. Izumi confesses with revenge as her motive for a deceased friend whose fatal accident was really a suicide, caused by Chihiro’s lies. The next day, Ran receives a new phone from Shinichi in the mail.
