Case

Situation

Yoshiaki Kamata lives with his father Hajime; his younger brother Mitsumasa; and his wife Sachiko. Even though all of the three have their own dispute with Yoshiaki, they were genuinely worried when he had not come down for his breakfast, so they went to his room and broke the door because it was locked inside. However, they only found him dead with a knife on him, and the room was quite messy.

The Mouris were invited to the scene because every member of the family admitted to having killed the victim on their own. To make things worse, another woman named Keiko Mitamura comes to the scene to admit that she was the murderer.

Murder?

Victim: Yoshiaki Kamata

Age: 34 years old

Cause of death: Blood loss caused by a stab wound on the back

Suspects: Hajime Kamata, Sachiko Kamata, Mitsumasa Kamata, and Keiko Mitamura

All four people admitted that they had killed the victim. All of them also had their motive to kill Yoshiaki. However, they could not tell the police how they killed the victim.

Since none of them was able to tell the police how they committed the murder, it is clear that everyone was lying to protect someone, despite having their own motive to kill Yoshiaki:

• Yoshiaki said that everything that his father had was not genuine all along, but he still lives thanks to his father’s not genuine assets.

• From Sachiko’s perspective, she was blamed by her husband for her infidelity while he was the first one to cheat on her. Moreover, Yoshiaki’s abusive behaviour almost got her to end her life, as she would have jumped off a building without Hajime’s words.

• Mitsumasa reveals that he is in a relationship with Sachiyo, which practically means they are cheating.

• Keiko Mitamura is Yoshiaki's ex-girlfriend, but probably broke up when the two learnt that they were half-siblings. In addition, she is still delusional that Mitsumasa is her boyfriend.

Kamata's family tree

Conan then decides to investigate the scene on his own, and when he is thinking outside, Ran shows up and they have a conversation about this weird case whereas everyone is lying to protect someone. He then asks Ran if lying to protect someone is okay, she replies: If she has to lie, she prefers the type of lie that is both gentle and does not hurt anybody.

Resolution

  Show spoilers »

Yoshiaki Kamata had heart surgery 2 years ago and is taking medicine till this day. His death was just an ironic accident. Yoshiaki had a heart attack this morning, forcing him to rummage through the things on his desk to find medicine. His rummaging caused the knife on the desk to fall, but it ended up pointing upwards. He fell when the pain was unbearable, just so happened to fall onto the upward-pointed knife, ending his life not long after.
