1) The police detective is smarter than stereotypical police officers and can better solve this case through deductive reasoning and an independent perspective.
2) The killer is portrayed as a mysterious and unpredictable villain like Batman's Joker character, making their actions dangerous and the story more interesting.
3) The victims are younger adults who are unable to defend themselves against the killer, though the reasons for their targeting remain unclear.
