Meitantei Conan

Synopsis

Conan, Rachel, and Richard are out jogging when Phillip Baker, the Eastern Branch Vice-President of Ojamanbou Cleaning Company, is crushed to death by a falling beam. Conan suspects Nathan Greene, the company president, to be the killer, especially after learning the victim dated Crystal Greene, the suspect's sister. During the investigation, Conan spots scratches from the opposite building next door and a groove on the company building's rooftop, then tranquilizes Richard to explain Nathan Greene is in fact the killer. Nathan tied a metal cable to the surveillance camera and steel beam, then, while using Phillip's harmonica as bait and watching him with binoculars from a mirror on the company's truck, manually moved the camera which caused the beam to fall on Phillip. As evidence, Nathan's reflection from the opposite building can be seen removing the metal cable on the same camera he used to murder the victim. Nathan confesses, stating Phillip broke up with Crystal for a wealthy woman, resulting in her having to work for another company where she later died in an accident, the same way Phillip was killed.
