Meitantei Conan › Season 1

Chapter 19 — An Elevator Murder Case

Ashiya Eiko is seen in her office building after hours walking about, leaving visible footprints behind, then leaves. Meanwhile, Ran is handpicked from thousands of girls to model for Ashiya Eiko's design company. Animosity is felt when Eiko's employee, Taniguchi Mika arrives. They both ride different elevators to their floors, but Eiko states she can not get through to her. Eda, the security guard, takes them to check on Mika, instead they find her stabbed to death in the elevator. Although it appeared to be a robbery attempt turned deadly, Conan is certain that Eiko is guilty; however, he is unable to prove it as Mika's body was found in the elevator on the 8th floor and Eiko was on the 15th floor. With a few more clues, Conan tranquilizes Kogoro, revealing that Eiko left artificial footprints in advance to throw authorities off her trail. Next, she called Mika to the 15th floor and murdered her, then placed her corpse in the elevator with her back leaning on the door and then sent it to the 8th floor. As evidence, Eiko had no time disposing the bloody gloves she used in the murder, so she still has them. Eiko confesses that she murdered Miko in vengeance for stealing her clothing designs and selling them to her rivals. (Source: Wikipedia)
