It was three or four o'clock in the afternoon, and the sun came in from many directions, and the large open room was bright and quiet. Su Mian sat behind the computer, but her eyes were fixed on other people.
He was probably a little tired. The opposite Xu Nanbai was leaning back in the chair with his arms behind his head, as if he was closing his eyes and resting. Not far away, Nag, Xiao Zhuan, Han Chen... are all busy, a tense but peaceful atmosphere pervades the room.
Seeing that there was no one left or right, Su Mian entered the encrypted password on the computer and entered the background of the working system. A monitoring program has been installed here to record everyone's usage track today.
The first is nagging.
It took him roughly 30 minutes to go through all the files quickly. Then off the line. Su Mian looked up and glanced at him and Xiao Zhuan in the most remote and dark corner. He sat in front of the microscope and other equipment all afternoon and didn't move. Obviously, he was all focused on fingerprint restoration.
The second is Xiaozhuan.
Although Han Chen gave him the task to help nagging. But Su Mian knew very well that he didn't understand anything about the sophisticated technology of fingerprint repair. And Su Mian looked at it several times in the afternoon, and saw him moving things and arranging materials there. In the system records, his login and browsing time was the longest: it took him two hours to read the materials, the police report, the victim file, the analysis of the murderer's modus operandi, the police materials, and the police follow-up report. Times are average. Then, I watched it twice from beginning to end.
Su Mian smiled slightly when she saw this kind of online trajectory: It fits the style of his repeated study as a scholar.
Several people from the forensic department and the criminal police team were screening people from other provinces all afternoon according to the smoke bombs that Han Chen set off. So the system login time is very short. Even if there is, it mostly stays in the two modules of police report and murderer modus operandi analysis.
Then there is Xu Nanbai.
His login time is not long. It took me a while to read the police report before skipping to the follow-up report. The analysis of the victim's file and the murderer's modus operandi did not take him too much time, and only briefly browsed it. Finally, I looked at the police information again.
As for Lengmian, because he has been working with Han Chen, their online trajectories are exactly the same: first, they spend a short time reading the police report, and then spend a lot of time studying the victim's file and the murderer's modus operandi. At the same time, Su Mian saw that they were constantly marking on the map. During this period, the follow-up report was also reviewed.
…
After sweeping through everyone's internet trajectories, Su Mian's heart thumped a little faster. She turned off the computer, stood up, and decided to walk around and take a look.
—
The first to go is naturally the key surveillance area: the fingerprint repair group.
As she expected, Xiao Zhuan couldn't get involved in the nagging work. When she walked over slowly with her hands behind her back, she saw Xiao Zhuan carrying things and sorting things in the office. And the nagging of the old line, at this moment, seems extraordinarily focused and authoritative. He even put on a white coat and thin gloves, and his handsome face was full of seriousness. He lowered his head and stared at the microscope, his slender fingers slowly turning the fingerprint print, even Su Mian approached without noticing it.
"Xiao Zhuan, highlight." He gave the order.
"Oh!" Xiao Zhuan stuck out his tongue at Su Mian, and hurriedly leaned over to attack him.
Su Mian stood there quietly watching, until Nagging let out a long sigh of relief, and leaned back in the chair: "Take a break before fighting. Xiao Zhuan, water!" Xiao Zhuan immediately offered the mineral water with both hands.
Su Mian smiled and looked at him with his hands: "Nagging, you really know how to call Xiao Zhuan."
Nagaka turned his head and saw that it was her, and smiled: "Xiao Bai, let me have the addiction of being the boss too."
Xiao Zhuan, who was on the side, interjected: "Smelly! I'm not your little brother, I'm just helping you. I was born as Xiaobai, and died as a ghost of Boss Han!"
Su Mian chuckled, and the nagging was also amused.
Su Mian asked again, "How's it going?"
When it comes to majors, Nag immediately showed an inscrutable expression, but he couldn't hide his pride: "What do you think? You know, my fingerprint repair technology ranks first in the country. Don't say anything else, I'm off work today. Before, I could at least fix an outline, hehe."
Su Mian's eyes were dark, but a happy expression appeared on her face: "That's great!"
—
Several rooms on the second floor have been cleared out. Xu Sibai Xijing, another person who does his own thing, didn't say hello to anyone, and moved into one of them with Xiao Yao first.
When Su Mian pushed open the door and went in, she saw sunlight jumping in from the opposite window, and the whole room was silent. Xu Sibai also changed into a white coat and sat at the desk, his dark brows furrowed. He was looking at the pictures of the corpse on the computer, and he didn't even hear Su Mian knocking on the door.
"Hello." Su Mian called out softly.
Xu Sibai was startled, put down the mouse, turned to look at her, "Jin Xi, is something wrong?"
"It's alright, come here for a walk." Su Mian swayed to the table and stood beside him as usual, "Did you find anything?"
Xu Sibai smiled lightly.
Like nagging, when it comes to professionalism, this man will also bloom with a quiet and dazzling luster. There is no longer the usual arrogance and coldness, nor the embarrassment and loneliness that he hesitates to talk about when getting along with her these days. He put one hand on the armrest of the chair and slid the mouse with the other hand, and his voice was so clear that it was like spring water: "Come and have a look."
Su Mian couldn't even ask for the two of them to get along with each other without any gaps, so she immediately leaned over and smelled the light breath on his body again. The smell of formalin mixed with the smell of blood was only reassuring. Long-lost peace of mind.
"Look at the corpses at the explosion site first." He pointed to several photos on the screen, "What do their postures have in common?"
Su Mian was very fascinated by it, but after watching it for a long time, she didn't see any mystery. In the end, she had to answer somewhat uncertainly, "Could it be that... they are all lying on their backs?"
Xu Sibai smiled: "Yes."
Su Mian dragged her chair and sat down in surprise, her face almost touching the screen. Alas, most of the deceased in the photos were lying on the ground, whether their faces were on their sides or their faces were thrown.
I just listened to Xu Sibai's explanation: "I have seen all the photos of the explosion, and the vast majority of the dead, even if their upper body was blown off, were still in this position. After the explosion, the limbs of people broke off from a standing position, and they were lying forward and backward. The normal ratio should be one to one."
Su Mian's eyes lit up, "Could it be that the criminal did it on purpose, designed it? Let the victim die on his stomach?"
Xu Sibai nodded, brought a piece of grass paper and a pencil, and drew a schematic diagram with a few simple strokes on the paper: "I used a computer simulation, if you tie the bomb to the back of the waist, and then Putting a small-yield bomb on the chest may cause recoil, causing the upper body to fly out at an oblique angle, forming a prostrate posture."
