It was the wee hours of the following morning by the time the case meeting was over, but the police made a lot of progress. Looking at the three cases, the murderer had to be a local of City A. Moreover, the trajectory of his life should be very complicated such that he could come into contact with people from different walks of life.
As the second victim was only six years old and had a narrower field of movement, the police thought that they could start with the boy. The murderer should not be far from the boy's house or had direct or indirect conflict with the boy.
"Sigh, I've stayed up all night again. When can we close the case?" Bai Luo stretched her sore arms and complained to Yin Tao and Xia Jin beside her.
"It won't be long." Xia Jin looked exhausted too.
"It's really not easy for you detectives." Yin Tao looked at the haggard duo and couldn't help but sigh.
