Conan, Kogoro, and the police continue to search for clues to solving the case. Conan learns more about Tatsumura, the current owner, Satoshi, and the company's history from one of the employees. Satoshi is unwilling to fire Tatsumura because he was responsible for saving the company years ago. Conan learns that Fumiko used to be a nurse, and that she made sure Tatsumura got a check up the day before he got murdered/kidnapped. Everyone gathers to hear Kogoro's deduction, and Conan reveals the culprit's trick.
