Resolution

• Evidence
  • Katsuhiko’s heart literally stopped on Valentines Day. And beside his dead body, a cigarette and a chocolate bar were found among his usual items.
  • Before the tragedy, he was in his small party where they ate and drank. In lieu with Valentine’s day, each girl gives a guy a bar of chocolate, to which the guy would consume preferentially.
  • Conan noticed that even though her son died, Katsuhiko's mother is doing the dishes.
  • Susumu drank the coffee, which makes his mother mad, but she suddenly had a change of heart and gave him some cake.

• Conclusion

After putting Inspector Kogoro to sleep with the Stun-Gun Wristwatch, Conan, using the Voice-Changing Bowtie, revealed how Katsuhiko’s real killer was his mother.

Katsuhiko does not smoke with filters, that’s why Naomichi’s attempt to poison him through this, failed. Meanwhile, his mother knew his habits, and put poison in his coffee, knowing that he wouldn’t eat the antidote in the cake. The reason she had a change of heart when Susumu drank the coffee is because he is drinking the poison, so she quickly gave him the antidote in the cake so he wouldn't die. She also framed Yoshimi by switching the chocolates she gave him with a half-eaten bar that Katsuhiko apparently ate. Though his mother immediately washed all the cups and switched the chocolates, poison lingers much deeper than the naked eye could see.

• Motive

When her husband’s business took a turn for the worse, Katsuhiko's mother had to think of the quickest way to acquire Katsuhiko’s estate, and save the house.

Katsuhiko is an orphan who was adopted by his only living relative when he was a kid. His foster mother knew he fell in love with Yoshimi since she closely resembled his deceased mother, so she framed her.
