1 - 732: The Ex-Boyfriend Living Next to a Crime Scene (2)

Conan pieces all the clues together: the suicide note with somewhat strange contents, Shukichi Haneda mentioning a "well-prepared move", same phone models of all the family members, the trick behind the bedroom door closing upon Sakurako and the victim's husband entering the room, and the victim's phone on the floor.
