The Crime that has Zero Possibility to Be Proven

Conan, Kogoro, and Ran pass by a woman named Kyouko Takahata who passes out upon receiving a phone call that her brother-in-law, Itsurou Soejima was found dead in her home. They head to her house along with the police to discover that the drunk Soejima died when he fired a shotgun toward the ceiling causing a chandelier to fall on top of him. The police conclude it was suicide, however Conan believes it was a carefully planned murder. Conan investigates and discovers that in the past year, Takahata was involved in all the alcoholism incidents that almost resulted in Soejima's death. After gathering the evidence, Conan tranquilizes Kogoro to reveal his deductions. Conan reveals that Takahata called Soejima to her home and had prepared the alcohol and shotgun to tempt Soejima, who is a recovering alcoholic.
