The next morning.
The sun is shining and the breeze is gentle. The humidifier in the window, spewing a thin layer of water vapor, seemed to be the most peaceful and beautiful morning.
As soon as Su Mian stepped into the office, she saw that someone was already sitting in her seat.
It was Xu Sibai.
He was wearing a brown coat, white shirt, and slacks as usual, leaning back in his chair, reading one of her books. Behind him, Xiao Yao was chatting with Xiao Zhuan.
Next to him, behind the chattering table, sat Xu Nanbai. Nagging was talking to him enthusiastically. Hearing the movement, several people looked up.
Su Mian greeted Xu Nanbai with a smile, "Morning, Senior Brother."
Xu Nanbai smiled and nodded to her.
She walked to her table again, when Xu Sibai had already stood up, she pressed his shoulder: "You sit, you are a guest."
Xu Sibai smiled, and in his clear eyes, there was a bright wave.
After all, the two have not seen each other for several days. He didn't look the same as before, his face seemed to be a little thinner, but his expression was calmer. Now that Su Mian was facing him, he felt a little strange.
This feeling made her uncomfortable, so she just stared at him with dark eyes.
He seemed to understand her unspoken words, his eyes softened, and he asked, "How did you feel when you went to Beijing?"
Just as Su Mian opened her mouth to answer, her heart skipped a beat, remembering that she had discussed with Han Chen yesterday whether Xu Sibai might be one of the killers.
She looked sideways at his look.
His expression was very gentle, and there was nothing strange about him talking about her going to Beijing.
Su Mian calmed down and replied, "I just played around. Oh, did you eat the roast duck I brought you? I asked Xiao Yao to bring it there."
Xu Sibai frowned slightly: "It's not delicious."
Su Mian laughed. Xu Sibai also smiled slightly.
This made Su Mian feel very good, it was like going back to the past, that's how the two of them got along. She chirps crookedly, and he is aloof and cute like a child.
After chatting for a while, Su Mian raised her head and looked at everyone in the office.
In addition to Xu Sibai and Xu Nanbai, several people from the forensic department and the criminal police team also came. The small office is very crowded. Everyone is waiting for the start of a new case.
At this moment, Han Chen and Leng Mian finally walked in. Leng Nian also carried a large stack of documents in his hand. Everyone looked at them, and the atmosphere became a little serious.
And Han Chen's eyes swept around, and Su Mian and Su Mian were in the air, and then moved away without a trace.
He told Xiao Zhuan to close the door, and then distributed the information to everyone.
Su Mian secretly observed their expressions. Everyone was a little stunned when they opened the "4.20 Major Cases Brief" in their hands.
This is the plan that Han Chen made yesterday: no side-talking, no unannounced investigations - straight to the point, throw the case directly in front of the killer, and catch him off guard.
—
After a while, Han Chen had briefly introduced the situation of the case, and then said: "This is an old case, because recently, there are signs of escaped criminals in our province, so we will do some investigation first. Report to the director, the whole process of the work requires absolute confidentiality. Therefore, externally, we announced that we are investigating the murder of the wealthy business mistress; internally, we put all our energy on this case. Therefore, I also specially invited Professor Xu and Forensic Doctor Xu, assist us in our work."
Xu Nanbai was looking down at the documents, and nodded when he heard the words. Xu Sibai turned directly to the back, where the victim's autopsy report was.
In the end, this news came too suddenly, and everyone else didn't know what to say.
Several foreign aids from the Forensics Division and the Criminal Police Team expressed their opinions first: "Team Han, if you have any work arrangements, you can say that we will do our best to complete them."
Han Chen nodded, his eyes swept over them one by one, his eyes calm.
The cold face remained silent. Xiao Zhuan probably knew that the big case back then had something to do with Su Mian and Han Chen, so he just shook her hand under the table, expressing his inner nervousness and excitement. Nagaw flipped through the information and clicked his tongue: "Boss, this case is really big enough. How do we investigate it, and where do we start?"
Han Chen replied, "We already have some very valuable clues."
Everyone looked up.
Han Chen took out two photos of T and Xin Jia and put them in front of everyone: "It has been found out that the two of them are members of the killer organization."
Most people don't know Xin Jia's identity, and they all show a surprised expression when they hear it. Nagging murmured: "What the hell, she's actually a killer?" Xu Nanbai looked surprised: "Xin Jia?" Xu Sibai and Xin Jia didn't have much contact at all, so he didn't respond when he heard the words. Even Xiao Zhuan turned to look at Su Mian in surprise, "No way... God!"
Han Chen briefly recounted how he got along with Xin Jia in the woods that day, and then said: "Xin Jia said before her death that there were still 7 survivors of the killer organization. indivual."
No one spoke in the house for a while. Su Mian looked at everyone's faces, but still couldn't see any clues.
"She said that these people have been staying in..." Han Chen paused, "a province in the south. But recently, because of T's death and our investigation, they may have come to K province, so she reminded me Watch out."
Still no one spoke.
However, Han Chen has already issued a series of instructions: "Professor Xu, Bai Jin Xi has already made a few simple criminal psychological portraits based on the victims and case files. I would like to ask you to help her improve the portraits."
Xu Nanbai and Su Mian looked at each other, seemingly subconsciously reaching out and turning the Buddha beads, and replied, "Okay."
"Forensic Doctor Xu." Han Chen looked at Xu Sibai, "Please review all the autopsy reports again. If it can help us in our investigation, that would be the best."
Xu Sibai: "Yes."
Han Chen turned to look at the forensic department and the criminal police team: "Please start an investigation immediately. In the last three months, the list of people who came to our city from southern provinces and cities. Especially with the criminal psychology portraits of Su Mian and Professor Xu. , corresponding personnel. And collect all their whereabouts information, DNA samples."
They answered in unison.
"Leng Nian, you follow me." Han Chen opened a map of Beijing and hung it on the whiteboard behind him, "You and I are responsible for drawing the murderer's crime map according to the geographic location of each murder, so as to pinpoint where the murderer was in the past. The scope of Beijing's activities is the largest search for suspects."
"Yes."
The clues left by Xin Jia, the criminal mental image, the autopsy evidence, the screening of personnel from other provinces, the geographical scope lock... He arranged it in an orderly manner, and every line seemed to have something to do. This made everyone look a little eager to try. Xiao Zhuan even sighed, "That's great, you're afraid that you don't have any clues and don't know how to investigate. Look, our Black Shield team is a perfect combination, and all roads lead to Rome!"
Nag also nodded: "Yes, I suddenly feel enlightened."
At this time, Han Chen also looked at the two of them, and took a small evidence bag that was sealed several layers from Leng Nian's hand. Inside was a fingerprint imprint.
To be precise, it was half a crippled and fuzzy fingerprint.
Han Chen said: "In the end, it's your two tasks. This is the half of the extremely precious fingerprint evidence extracted from the crime scene. I brought it back from Beijing. At that time, due to technical limitations, fingerprint identification experts did not have access to A valid identification result is obtained. This time, we will re-lock the scope of the suspects and re-examine the fingerprints for comparison. Nag, look at you, your fingerprint identification technology is not inferior to the Beijing experts. As long as you can gain something, we will Maybe one of the killers can be identified. Xiao Zhuan, cooperate with you. The fingerprints must be preserved and cannot be lost or damaged."
In the eyes of everyone, Nagga carefully took the half of the fingerprint, and his eyes lit up.
