Events of Criminal Case
Susie became a suspect after the player and Maddie found a check with her signature at the cafe the inventors go to. She was shocked to hear of her father's murder, and hoped it would not be true given her father's hatred of machinery. When asked if she knew about this saboteur that was recently discovered, Susie said she would not know as she did not understand what the inventors usually talked about.
Susie was spoken to again after her hair was found on a chocolate box at the crime scene. Though she had trouble with trying to stop crying, she confessed she had a rendezvous at the Exhibition Hall, with a gentleman who offered her those chocolates as a token of his affections. They met before any visitors arrived, then Susie returned to work, and then she apologized for not bringing it up since hearing her father's death made it slip her mind. It was later revealed the gentleman who met with her was Charlie.
In the end, Susie was revealed to be the one behind her father's murder. After denying involvement, Susie admitted to the crime and said that Arnold was not the saboteur. As a Luddite, Arnold refused to let her daughter become an inventor and doubted about her intellect. When he saw Susie leaving the Inventors' Hall, Arnold confronted her and they argued. In a fit of anger, Susie unknowingly killed her father with an electric charge weapon she had invented. Judge Takakura sentenced her to 7 years in jail.
- As Susie turned out to be the killer of her own father at the climax of his murder investigation, she is one of the killers to commit domestic homicide.
