The killer is Dio!
After inspecting the crime scene, Emily compared the victim's wounds in her mind and confirmed her suspicions.
The pink-haired man mentioned by Oda Shizue and the blonde-haired man Rumi Yoshizawa spoke of are one and the same. He deliberately adopted such distinctive makeup and attire, making people remember his conspicuous appearance, thereby causing them to overlook what they should truly be noticing.
Even Emily had been deceived.
I originally thought Dio was so brazen, leaving so many clues for the police, because his criminal ego had inflated. But thinking about it now, while Dio seemed to leave many clues, not a single one actually pointed to him. Beneath his frantic actions lies a meticulous mind. Every step Dio takes has profound meaning. In all my years in this profession, this is the first time I've encountered such a crazed criminal genius.
