Zheng Guangming was locked up. Even without questioning, he told the police everything he did.
He told them everyone he had killed.
Besides the victims that had been found, there were still some that were not found. These crimes were normally committed outside the city.
He would observe the victim for more than a month before coming up with his plan. Hence, no evidence was found.
But, when the police asked him why he did all this, Zheng Guangming just smiled.
Normal psychopathic murderers would break down under their questioning no matter how calm they appeared at the start.
Zheng Guangming was different. From the start of the questioning, he didn't have any change in emotions. No one knew what to do with him.
He did explain the branded goods and the X-shaped scratches.
The victims deserved the branded goods.
The policeman questioning him almost hit him when he said this.
