In the courtyard of the Provincial Public Security Bureau, in addition to the main office building, there are several small buildings such as the Archives, Forensics Institute, and Criminal Research Institute. Trees are everywhere, neat and solemn.
In a corner of the courtyard several hundred meters away from the main building, there is also a two-story white building. From the outside, it is simple and uncharacteristic, and it is usually used as a logistics storage.
Today, this small building has been cleared out and officially hanged the "Black Shield Group" sign, becoming their temporary secret office location.
afternoon.
Su Mian carried a small stack of books and walked along a tree-lined road with Han Chen. In his arms, is a large box, filled with almost all her office supplies.
Such peers have the taste of returning to campus. Su Mian turned her head to look at him, his expression was very relaxed, and his dark eyes were also looking at her lightly.
Su Mian looked up at the small building not far away. Nag and Xiao Zhuan were standing at the door, carrying things inside. She snorted softly: "Han Chen, you are quite yin. When did Xin Jia say, 'They are in the south'. Where did you get those fake fingerprints?"
Han Chen's pace slowed down, he actually changed to holding the box with one hand, pulled down the zipper to open his jacket, and unbuttoned the top button of his shirt, and replied, "Am I supposed to be a stunner? What do you say, what do you expect? I'm arresting the seven-member group?"
Su Mian smiled, then looked around quickly, and whispered, "But this trick is really high. Everything else Xin Jia said is true: she is a serial killer, she uses poison, and there are seven other people, the only one. The one "in the south" alone is false. One false one is mixed with so many true ones, and the false one has become true. You even sent a few detectives to search for people from other provinces. That person listened to it. , most of them believed it to be true, thinking that Xin Jia did not expose him before his death, so he relaxed his vigilance."
Han Chen smiled lightly.
Su Mian continued, "The same is true for fingerprints. The criminal psychology portrait you asked me to do is genuine; the geographic search you and Leng Mian did were also serious; Xu Sibai's autopsy was also true. The fingerprints given to Nagau and Xiao Zhuan are fake. However, although the seven-member group was shrewd and cautious, from the archives, the bloody battles that followed were also very chaotic, and it was not impossible to leave half a fingerprint. This added to the The credibility of a fingerprint. It's just—" She looked directly at him: "You said that person, would you be fooled? Would you really take the risk and steal fingerprints?"
"Now he's naturally dubious and won't act rashly," he replied. "So we have to continue to confuse him until he believes it is true and finally takes action. At that time, we will catch the turtle in the urn."

The temporary office area of the Black Shield Group.
The first floor is actually an open hall, with concrete floors and mottled walls. There are a few offices on the second floor, but they haven't been cleared out yet.
Su Mian and Xu Nanbai were in charge of the criminal psychology section, occupying a corner of the hall with two desks and a whiteboard. Han Chen and Leng Mian, Nag and Xiao Zhuan, Xu Sibai, and a few others, each marked a place, and were busy for the time being.
Su Mian was staring at the computer, reading the dossier; the opposite Xu Nanbai seemed to be fascinated. At this moment, Zhou Xiaozhuan's voice sounded: "Everyone! What everyone saw yesterday was just a brief introduction to the case, today I have sorted all the details of this case into categories: police report, victim information, murderer committed the crime. Techniques, police information, follow-up reports, etc... are placed on the encrypted local area network for everyone to browse. In addition, according to Mr. Han's idea, I have also established a working platform for each team, and you can upload the latest work results at any time. Including Xiao Bai's criminal mental portrait, Xu forensic doctor's new autopsy conclusions, or nagging fingerprint identification reports, can be updated and shared at any time."
Everyone nodded. The results of each group are meant to be cross-referenced, and such electronic measures have improved the efficiency of team operations.
Su Mian opened the local area network system on the computer, and sure enough, all the information had been categorized, and it was clear at a glance. She opened the information about the victim and the murderer's modus operandi and began to study.

At that time, regardless of the innocent victims in the crossfire between the police and the bandits, some scattered single murders were not in her focus. Well, in addition to t marked by serial sniping cases, and Xin Jia, who only produces drugs behind the scenes, there are three serial killers in these files. The other two have yet to be seen.
Su Mian put the information on the first category: serial bombings into a subfolder and read it page by page.
First time:
Victim male, 48 years old, vice president of a listed company. On the day of the kidnapping, the safe at home was stolen and the amount of lost property was unknown; more than tens of millions of funds in bank accounts were transferred overseas. Later, the victim's body was found in a warehouse in the suburbs - to be precise, it should be a corpse, because he had been bombed into seven or eight pieces.
Su Mian held the mouse's hand and paused.
explode. Precise explosions using homemade ammunition. Obviously, in the seven-member group, there has always been such a blasting master. And the bombing that she and Han Chen encountered back then was probably the work of this person.
The victim of the second case, somewhat similar to the previous one, was a well-known collector. After the incident, all the precious collections in his home were looted. And his end was even worse. Not only was he blown into a lot of pieces, but he was also thrown into the downtown area with his mouth and nose sealed. Under the watchful eyes of everyone, no one dared to reach out to save him. When the police arrived, he was already in a pile.
The third case, the fourth case, the fifth case... Su Mian raised her eyebrows slightly, which was a little interesting. It turned out that although the later victims were mainly rich and noble, there were also ordinary white-collar workers or poor and petty citizens; the same explosion occurred, and some were thrown into the downtown area; some were thrown to the top floors of skyscrapers; thrown on the university campus. There are also various ways of explosion. Some are blown up in the middle, some are blown into five pieces, some are blown into eight pieces, and some are directly blown into meat dregs...
After reading this type of case information, Su Mian pondered for a moment and continued to look back. At this time, Xu Nanbai stood up, put his hands on the table, and looked at her with a smile: "How is it, little junior sister? What's the gain?"
Su Mian put down the mouse, leaned back, stretched out, and replied, "I just finished reading the information about the bombing. What about you, Senior Brother?"
"Almost, I also looked at some." He walked around the desk, walked in front of her, and looked at her with his hands. "Communication? Let me hear your portrait."
Su Mian nodded, also stood up, and picked up the whiteboard pen: "Senior brother, then I will show my shame first. You need more guidance. This senior brother can't be called in vain."
Xu Nanbai's face slowly burst into a smile, and the whole person looked extraordinarily elegant in the afternoon sun. He stretched out his hand to adjust his glasses: "The mouth is quite sweet."
"This is a serial killer with a very distinct personality." Su Mian stood in front of the whiteboard and said, "First of all, the most striking feature—he looks like a child."
