Jia Tianzi's eyes flashed: "That's right, it might have been 'collected like stamps' by the killer."
Guan Liang opened his mouth wide: "The killer has a fetish for collecting police badges. Does this mean he also has a habit of killing police? Could it be that we've run into a serial killer who specializes in killing police officers?"
Tang Yanqing and Jia Tianzi exchanged a glance and raised their eyebrows.
Tang Yanqing then lowered his gaze to look at the knife wound on Sean's chest. The cuts weren't arranged haphazardly but showed a regular spacing. This further confirmed the killer's highly orderly personality and fully validated his cold-blooded nature.
Even stabbing someone in the chest could be done with such calmness and methodical order... It shows his contempt for Sean and even for life itself.
Tang Yanqing narrowed his eyes.
