Chiba is unable to recall Naeko's face though notes his familiarity. During the investigation, Conan realizes the culprit's motif and has the police let the suspects leave. During the night, the police set up an itasha to lure the culprit out, revealing the culprit to be Tokuko Shigei. Tokuko was vandalising cars with obstructions on their rear windows due to the trauma of her child being killed by a car of the same condition.
