Conan arranges the red shirts in the order they were sent and folds them along the creases and deduces that the way the shirts were folded reveal a code. Elsewhere, Jodie spots Akai is on the floor where the bombing incident is taking place. Conan uses the cashier room's computer in order to search for a disaster that occurred in a snowy mountain on December 28. Okiya, who happens to be on the same floor, examines the red shirt and concludes the sender is related to a disaster that occurred on a snowy mountain and smiles slyly when he notices Akai in the crowd. Conan tranquilizes Kogoro and discloses that the bomber's behavior is inconsistent; He was desperate to search for the sender of the red shirts, yet he found the time to kidnap and strap a bomb onto the man. Conan then declares that the man strapped with the bombs is actually the bomber.
