In the entire apartment building, more than three hundred people reside.
These individuals were investigated by Qinzhou City's Criminal Investigation Team within a week after the incident.
Particular attention was paid to single males who were questioned in person.
Now, Wang Song's suggestion has narrowed the focus further to individuals with a history of lewd behavior or voyeurism.
However, such private tendencies might not be caught before, so how should they be judged?
The old method: it's still like searching for a needle in a haystack.
The special task force doesn't have a Forensic Doctor, but they do recognize the autopsy report from Qinzhou City's Criminal Investigation Team.
The cause of death of the victim is very clear, as are the signs of assault.
Meanwhile, the body is currently preserved in the morgue and can be re-examined at any time.
On the top floor of the apartment, Wang Song inspected the layout of the entire apartment once more.
