Subaru reveals that when the paper plane is unfolded, the symbols ··· — — — ··· is Morse code for SOS. The two give Subaru another plane they found with a different design; The plane contains the Morse code of zero with the design of a mobile phone signal on the other side. Subaru deduces that the plane means the victim is in a place with no cell phone reception, meaning he is held captive in a very tall building. The three decide to search for news on the television to find out if more planes were sent. They come upon the news that Ikou Daita, a man of a famous company, was kidnapped three days ago and they realize he is the one sending the paper planes. A paper plane with a different design was shown on the television; Subaru copies down the design and realizes the message tells them Daita is held captive in Beika city. Conan, who has also solved the mystery, tells Ran to search for tall apartment buildings with paper planes on the veranda. After doing so, they report to the authorities who find Daita chained to a ventilator on the brink of death. That following evening, Subaru is shown drinking bourbon whiskey.
