Resolution

The culprit is Tokuko Shigei. She persisted in those crimes for the sake of her son who died due to an accident. The cause of accident was inadequate caution. Due to all swim tubes, rubber rafts and things, the field of vision for the rearview mirror was obstructed. Unluckily, the driver didn't see someone pushing the stroller behind their car. That's why she targeted every single car that was imprudent enough to have their rear window obstructed. And that's why she etched the word "Die" as punishment.
