Attempted Murder
Location:Kasuga household
Victim:Ryuji Kasuga
Age:30 years old
Method:Stabbing
Culprit:Yoshio Komiyama
Fortunately, Kogoro and Conan arrive in time to stop him. Conan tranquillizes Kogoro and starts the deduction of this case.
Komiyama believed that the attacks were executed by Kasuga because they happened near the studio in deserted locations, which means the culprit probably was following the victims. And he deduced that the culprit was someone from the studio. Kogoro says that his affirmations are correct but the culprit isn't Kasuga, but the assistant, Riko Rokui. Conan via Kogoro continues explaining the pieces of evidence that she is the culprit.
First, the second victim heard a sound before being attacked, which sounded like a clattering sound of a sketching pencil. Kasuga doesn't carry anything, but his assistant carries those all the time. Second, there's a scratch at the staircase's poles the first victim was pushed. This means Riko grabbed from the pole when she tried to push the victim and the scratch was made with her wristwatch. Lastly, he says that a part of her wristwatch's metal band is shaped differently and looks new, so it probably was repaired in a hurry after it got damaged. She then confesses that she did the attacks because she hated the models. She was a fan of Kasuga and he asked to be his assistant, but the happiness of being his assistant was ruined when he scouted new models.
