Episode 606: Courtroom Confrontation IV - Juror Sumiko Kobayashi (Part 1)
Scenario: Sumiko Kobayashi is called to be a jury for a murder Tadashi Ishigaki. Toshio Iwamatsu, a burglar who broke into Ishigaki's home, is held accounted for the murder and Eri Kisaki is assigned as his attorney and Reiko Kujo acts as the prosecutor. Kogoro, Ran, and Conan attend the hearing where Ishigaki's housemaid and brother-in-law deliver their testimonies of discovering the body. Unable to find the murder weapon, the court ends without a decision and will resume the day after. During the session, Sumiko notes aloud that the painting in Ishigaki's room is upside down prompting Kogoro and Conan to investigate the room. Inside the painting, they find a document stating Iwamatsu burrowed money from Ishigaki. Conan deduces the culprit took a document and placed the painting upside down in his rush and discovers that a vase in the room is missing after Ishigaki's murder.
A murder case court is in session in which Toshio Iwamatsu is suspected of having killed Tadashi Ishigaki after burglarizing his home office.
While Iwamatsu admits the break-in, he vehemently denies the murder, even though a slip-up suggests that he might have been acquainted with Ishigaki. The case heralds yet another confrontation between Eri Kisaki, as Iwamatsu's attorney, and Reiko Kujo as the prosecutor. In addition, Sumiko Kobayashi has been selected as one of the jurors. Although nervous, she keeps the court's confidence and refuses to devulge any details to the pestering Detective Boys members Ayumi, Mitsuhiko, and Genta.
At first the trial appears to be inconclusive, as there is no practical evidence of Iwamatsu being guilty of the murder. However, on a crime scene photo Kobayashi-sensei notices that the picture in Ishigaki's office - a rather odd piece of art of which a copy is also hanging in the Teitan Elementary principal's office - is actually situated pointing upside down. Intrigued, Conan, Ran, and Kogoro investigate the scene, along with Kujo, and on the back of the painting they discover bloodstains and an IOU for a large sum of money made out to Iwamatsu, which would provide a motive for murder. But Conan notices two more peculiarities: the imprint of a vase on a nearby cabinet, but with the vase gone, and the strange nervousness of Ishigaki's housekeeper, Yukie Hara.
