It appeared that Kikuyo had a 10 million yen debt and needed the insurance money to pay it. So, the police staff and Mr Muneyuki started accusing her and as she was about to be taken to the police station, Sonoko was stunned by Conan's stun watch and stopped them. After explaining the trick used and the evidence, Muneyuki gave himself in. It turned out that during Christmas, while Muneyuki was cleaning the things of her late daughter, he found the broken box of the tie her daughter gave to Moto, her husband. And when he went to the airport, wanting to give the tie to Moto, instead of seeing a griefing man, he saw a cheerful man together with Kikuyo.
