"You mean, you're not sure how surveillance is broken?"

"Yes, yes."

Wang Yan bowed his head a little weakly.

"I'm actually a little sleepy every time I work the night shift, and we are alone in the monitoring room in shifts, so I can't hold on, even if I know that there is no other person to help watch, I still can't help but fall asleep."

He touched his nose, "It's just that I've never broken the monitor." ”

"It's fixed now?"

Wang Yan looked up at Shen Siyan and found that her expression was very serious, so he knew that Shen Siyan must be very concerned about the content of the surveillance.

He became more and more weak-hearted, afraid that Shen Siyan would be angry, so he hurriedly said everything that should be said honestly.

"Officer, I don't know how to get this kind of thing, and I don't dare to tell the boss, so I found someone to fix it myself, and they said that the monitoring was fine, but the computer was moved, and a section of the monitoring was deleted."

So it's not like somebody is covering the surveillance or something.

Shen Siyan became nervous, "Did you recover then?" ”

Wang Yan shook his head.

Shen Siyan's expression darkened a little, "Can't you recover?" ”

Now that all the words have been said, Wang Yan has nothing more to say.

"I secretly found someone here and said that if you want to recover, you can do it, but it takes a little effort and you have to add money."

His voice was a little quieter, "Public monitoring, I don't really want to spend money, I have a bit of luck, thinking that it was night during that time, and there were not many people, so I guess there was nothing to do, so I didn't fix it." ”

Shen Siyan was a little angry.

"You did something wrong yourself, and you don't even know how to compensate?"

Wang Yan just lowered his head and didn't speak.

Shen Siyan sighed and tried to calm down.

"Where was the surveillance deleted, and for what time?"

She actually had a hunch in her heart, but she still didn't give up.

The results speak for themselves.

"It's after eight o'clock the night before yesterday, a few on the third floor, and a few monitors on my floor."

Shen Siyan took a breath and spit out heavily, "You bring it out, I'll take a look." ”

"Uh." Wang Yan paused, and his voice became quieter, "I won't ......"

Shen Siyan didn't take a breath, and almost wanted to slap him on the head and yell.

Fortunately, Lu Qian walked up, "I'll come." ”

Shen Siyan nodded while looking at Lu Qian aggrievedly, which made Lu Qian even more distressed.

He quickly called up the surveillance.

Shen Siyan looked at her husband with bright eyes and expectation, and sighed that it was Lu Qian who brought it today, not Gu Yanyan, Gu Yanyan would definitely not do this.

Without waiting for Shen Siyan to ask, Lu Qian said: "The monitoring on the third floor can see that Xu Changchun's office and changing room are gone, and the ...... on this floor Nothing can be seen in the monitoring room. ”

Hearing this, Shen Siyan held his forehead, lowered his head and was silent.

Lu Qian became worried, "What's wrong?" Headache? ”

Shen Siyan shook his head, "It's okay, I guessed it." ”

She raised her head, feeling a little better, "I guessed that there must be something wrong with the surveillance, after all, this is the most important part of destroying evidence." ”

Lu Qian looked at her pursed lips and knew that she was still a little uncomfortable.

"Although it has been deleted, it is not impossible to recover it, and maybe something can be seen elsewhere?"

If there is the same person in two non-adjacent monitors, you can also find the person's route, and if there is only one monitor with this person, it can also be inferred where the person may have gone.

The difficulty is that there are too many people in the hospital, and it is not easy to find.

Shen Siyan understood that there was no other way at this time, there was nothing else in the place where the body was buried, the office at the suspected crime scene had also been cleaned up, and the body was still so strange, except for monitoring, Shen Siyan didn't know where to start.

"I'll take the monitoring back, let's check it together, and then let Chengyi come over and try to fix the monitoring to see if anything can be found."

Lu Qian nodded, "That's the only way." ”

Before it was time to get off work, Shen Siyan simply went back to the bureau directly, while Lu Qian received a call from Yin Jie and went back to the company.

The people who secretly protected Shen Siyan were still there, and this time they were even more cautious than last time.

Fortunately, Shen Siyan entered the bureau and never came out.

She took the monitoring back and explained the situation clearly, and it was Gu Yanxi who collapsed first.

"Oh my God! It's too much, I'd rather the murderer get rid of all the surveillance now, so I don't have to check, it's a lot, I think I'll be blind. ”

Looking at her living treasure, Shen Siyan was in a better mood.

"Do you regret how to become a police officer?"

This Gu Yanyan didn't say that she regretted it.

"I do this, and I never regret it......"

However, she changed the topic, "If there is a question on the Internet about how difficult it is to be a policeman, I must complain about it, my day to investigate the case is enough to spend my brain looking at strange corpses every day, and I have to stare wide-eyed to watch the surveillance, and the physical and mental torture is indispensable. ”

As she spoke, she pretended to cry and put her head on Shen Siyan's shoulder.

"Siyan, I'm so pitiful."

Zhang Nanmu couldn't hold back, reached out and patted her on the head, "What are you pitiful, it's not just you who watch alone, so many people are with you." ”

Gu Yanyan straightened up, covered her head, and was aggrieved.

"But I'm still ...... young"

"Stop, stop!" Liu Jingjing couldn't help it, "Hey, hey, don't think that I won't dare to beat you when you're young, no matter how much you scream, Team Zhang won't be able to save you!" ”

Gu Yanxi was stunned for a moment, and looked at Liu Jingjing suspiciously.

Liu Jingjing looked at her and Zhang Nanmu like a little fox, and the crossing in her eyes must have made Gu Yanxi stop her voice instantly.

God, when did Liu Jingjing know about her and Zhang Nanmu?

Gu Yanyan covered her face, and hurriedly said: "Don't worry about leaving it to us here, let Chengyi come on, and you must resume monitoring." ”

Shen Siyan snorted and laughed.

Zhang Nanmu turned his head to look at her, "Siyan, you go and see the corpse first, see if you can find anything, and we will go with you to ask Professor Xie at night." ”

Shen Siyan nodded, "Well, I know Team Zhang." ”

She turned back to her dissection room, and suddenly paused.

"By the way, I have a record in my notebook, the changing room and the deceased's office are on both sides of the corner, the windows are very close, I tried, if you enter through the window, there is no problem at all, and the deceased has always had the habit of opening the window, I think you can find out if the inner courtyard is monitored by the two windows."

Gu Yanyan's eyes lit up, "Wow! Siyan, you're amazing! ”

She rushed up and gave Shen Siyan a hug, but before she let go, she felt a little cold in her neck, and quickly let go.

Zhang Nanmu's voice was a little colder, "Well, the situation is understood, you are not needed here, go back quickly." ”

Shen Siyan touched his nose.

Jealous men are so scary, she can't be hugged by a woman.

But of course Shen Siyan didn't say anything, and hurried back to the dissection room.

The case seemed to have made no progress, but it still couldn't escape these careful policemen, and after night fell, everyone was ready to stay up all night, and Gu Yanyan screamed "whoosh".

At the same time, Shen Siyan pushed open the door with a "bang".

"I saw it!"

"There's something new!"

The two voices thought of it at the same time, which made the hearts of all the policemen present with sour eyes and tears cheering.

Gu Yanyan hurriedly went over and paused the monitoring.

"This surveillance, did you see this woman on the air conditioner? Sure enough, it's the same as Siyan said! ”

She turned her head to look at Shen Siyan.

"Siyan, what did you find there?"

Shen Siyan covered the back of his neck and turned around to show them, "In this position of the deceased, there is a needle eye, which has been checked, it is a needle for injection, the deceased must have been injected with drugs, resulting in instant failure of functional organs, what specific medicine, ask Professor Xie in a while to see if he can know something." ”

Zhou Manshan, who was following behind Shen Siyan, also walked over.

"I checked the window marks given to me by Siyan, and I really thought it was damaged, and I also asked the comrades at the scene to bring me fingerprint samples, but unfortunately, the windows were wiped by the cleaners, only Siyan, the cleaners and the little assistant of the deceased."

Everyone was a little regretful, but not too sad.

"It's okay, anyway, I already knew that there weren't many clues left."

Zhang Nanmu soothed a few words, and turned his head to look at the monitoring, "Since you're here, let's take a look at the monitoring together." ”

After he finished speaking, Gu Yanyan replayed the monitoring.

This monitoring is relatively far away, and it is not very real, but it can be determined that the murderer did jump from the window of the changing room to Xu Changchun's office by the air conditioner as Shen Siyan thought.

Suddenly, Zhang Nanmu pressed the pause button and pointed to a place under surveillance.

"Look at this hair, it's a woman, and the figure also fits."

Shen Siyan thought for a while, "It's a bit similar to Duan Min. ”

Everyone was stunned.

Shen Siyan continued: "But I still think it shouldn't be her." ”

This time, Zhang Nanmu denied Shen Siyan's words with a straight face, "You are just a subjective judgment, and now that the monitoring shows the situation, we should bring her over for questioning." ”

Shen Siyan's guilt reappeared this afternoon, and he couldn't help but refute Zhang Nanmu.

"You're suspicious, what if it's not her? Isn't that a waste of time? I've asked everything I should ask, what else can you ask for anything new? ”

Zhang Nanmu glanced at Shen Siyan, who looked excited.

"You are not a professional policeman, your main job is a forensic doctor, and many things are naturally not as good as our policemen."

The two men disagreed again, and the others did not dare to speak.

Shen Siyan still wanted to refute something, but Zhang Nanmu waved his hand, "Okay, this matter is settled, I will accompany you to find Professor Xie." ”

Without giving Shen Siyan a chance to refute, Zhang Nanmu arranged them one by one.

"Xiao Wang and Xiao Liang went with me to ask Duan Min. Manshan, you take someone to check the deceased and Duan Min's office, and Jingjing takes someone to Duan Min's house to investigate, no problem, right? ”

"Yes."

Shen Siyan glared at Zhang Nanmu unwillingly, but was still pulled out by Gu Yanyan.

She knew that no matter how much she believed Duan Min, Duan Min would be listed as a key suspect by Zhang Nanmu, she couldn't change anything, it was better to investigate the case and find out the clues as soon as possible.

It was a coincidence that Professor Xie was waiting for them in the office.
