After a thorough investigation, Conan drops hints allowing Kogoro to solve the murder. Kogoro reveals that the murderer used an unknown object to loop around Moroguchi's hand from the window. After the murderer gave Moroguchi poisoned coffee, he left the room, locked the door, and used the unknown object to send it key back to Moroguchi's hand. The only object fitting this description was the interviewer's Kakuji Dejima cassette tape strings. They reveal that the forensic team should find Moroguchi's blood on the cassette tape. Dejima confesses and reveals that he murdered Moroguchi in vengeance for his friend, Akiba. Akiba was Moroguchi's assistant and was forced to be a test subject for murder ideas which eventually resulted in Akiba's death. Since the police were unable to determine how Akiba was killed, they ruled it as a suicide and Moroguchi was left unpunished. Later that day, Ran asks Sato about the ring on her ring finger. Sato replies that her friend told her the ring was a charm that would keep bugs away and accepts Takagi's proposal to use his ring as a replacement to the charm.
