Zhao Yu pointed to the white boards and said, "Look... The killer chose to kill people in either abandoned buildings or empty houses. These places were always nondescript and were far away from urban areas, so as not to attract anyone's attention!"
He paused, then added, "If it hadn't been for the third case, the police would not have been able to connect these cases at all, nor could they have possibly known that they were not suicides, but murders!"
Zhao Yu patted the white boards as she said, "The killer chose his targets very carefully. Although the identities of the victims were different, most of them did not have a steady jobs or families nearby. Thus, the killer knew that if they disappeared, no one would report it to the police for quite some time!"
