Meitantei Conan

Synopsis

Reika’s drenched corpse is pulled from the bathtub. Kogoro finds that she had been bound with rope, duct taped, and her clothes were soaking wet. After accidentally turning on the shower and being warned about getting wet, Conan tranquilizes Kogoro and asks the men to remove their jackets and he takes note of where water stains are located on the men's shirts before revealing Takashi as the murderer. He rejoined Yuji in searching for Reika alone, giving him the perfect opportunity to murder him. Takashi then caused a power failure and smashed a window to make it look like the murderer escaped. He took advantage of the darkness and attacked Ran, who was chosen at random; gaining a witness to confirm that Reika was held underwater in the same manner as Yuji was the target in this incident. Though it appeared Reika was drowned the same way, she did not. Reika was duct taped to the bottom of the bathtub with the shower-head turned on to ensure she drowned slowly and quietly, thus solidifying Takashi’s alibi. As evidence, his elbows have water stains on them when he removed Reika, as he rolled up his sleeves. Takashi confesses, stating Yaeko was killed by Reika and Yuji. Yaeko only had one spare life jacket including the one she had on, meaning they took the life jackets and left Yaeko to die. He also talked with Reika and Yuji and both confessed to killing Yaeko, before being killed themselves, and all this was done in revenge. Yone, while devastated at this revelation, disapproves of Takashi's actions.
