748: Chapter 691 Screening 748: Chapter 691 Screening The footprints of the worshipper Jiang Yuan had found near the burial site weren’t particularly unusual.

The person of average height and age, slightly lighter in weight but still within the tens of millions of ordinary weights, couldn’t directly point to Old Nine’s identity.

However, the act of worship exposed much more.

It indicated that Old Nine had an emotional connection with the buried victim, regardless of whether it was love, hate, grievances, or human suffering.

In short, the act of worship completely dragged the case back from a serial murder to an ordinary homicide.

The scariest aspect of a serial killer is actually their antisocial nature.

If you have a serial killer who desires nothing, that is the most helpless situation, and most of those who do as they please are also very difficult to investigate.

Even if the police manage to connect with their thought process, it doesn’t necessarily lead to effective investigation.

Crimes of passion are much better.

Despite it seeming like a person may know many others, in reality, the social limit of a normal person is about 500, with around 150 that one maintains contact with.

Tao Lu directly drove to the scene.
