Wang Chao stared at the picture Gray had shown and then at the fingerprint identified by the forensic expert. His gaze finally landed on Gray, and he said coldly, "Why are you doing this?"
He had never met Gray before, and they had no enmity. However, on their first encounter, Gray had shown an attitude of hostility towards him. Now, the moment Wang Chao entered the murder scene, Gray had produced his fingerprint, which had been collected at Massachusetts General Hospital.
Clearly, Gray had come prepared!
"I don't know what you're talking about," Gray said, pointing his gun at Wang Chao, with a frigid expression. "Wang Chao, we currently suspect you of this murder. It's best if you surrender quietly, or I have the authority to shoot you."
He placed his finger on the trigger, ready to fire at any moment.
"What evidence do you have to prove I'm the killer?" Wang Chao scoffed.
