Notes From A Criminal Investigation 7 Chapter 78

This woman provided very clear clues that Huang Lingling did have experience in prostitution. The initial judgment of the Huzhou Criminal Police Detachment was not completely wrong and was very reasonable.

Jiang Qingxian quickly found Owen and reported the results of the investigation. He then said, "The murderer is Huang Lingling, there is no doubt about it. If we put pressure on her, she might confess."

The police do not necessarily solve a case by identifying the suspect through evidence, but can also break through the criminal's psychological defenses through interrogation and make him confess. This is a way to solve the case. Jiang Qingxian is an old criminal investigator who has experienced similar cases.

Owen said: "This method can be used for ordinary cases. This case is a serial murder case. The murderer's psychology is different from that of ordinary people. In the case of insufficient evidence, interrogation is difficult to be effective. If it is not done well, it will be a half-cooked meal. We have to continue to dig deeper and lay a solid foundation."

The second task force then divided into groups to question Jing Hong and Zeng Zhaomin.
