After re-watching the murder on the camera, Conan realizes how they will find the murderer. After tranquilizing Kogoro, Conan has the wrestlers wear Wolf Face's mask and tells them to walk in a straight line. The wrestler Iwao Ushigome is then labeled the murderer. Conan reveals that the Wolf Face in the camera had difficulty walking since he was not used to wearing the Wolf mask. As evidence, Conan reveals that the mask Ushigome was wearing was ripped and blood seeped onto the second mask he was wearing underneath; They find the second mask in Ushigome's jacket with Nagase's blood. Ushigome proceeds to attack the wrestlers but is incapacitated by Ran.
