"I've noticed that the same condition related to the killer exists at all four crime scenes."
Special Investigation Team, in their office area, Agent Channie, with her suit jacket open, stood up from her chair. Facing everyone's gaze, she analyzed expressionlessly:
"First, after subduing the victims, the killer stuffed a white towel into each victim's mouth.
Second, the killer cut off and took away the tongues of all four victims, which must be related to the victims' actions or thoughts before their deaths.
Eighty percent of the world's serial killers have a sense of ritual. Currently, without finding any connection between the four victims, exploring the reason behind the killer's tongue removal and looking for the source of those white towels, I believe, is a direction for the investigation."
"Good."
Luo An nodded, gesturing for Channie to sit down while recalling her profile in his mind, particularly noting her exceptional memory.
