It was already dark, and only the policemen on duty in the Municipal Public Security Bureau were still busy.

Su Nan went upstairs and entered the office in three steps and two steps, and as soon as he entered the door, he smelled the fragrance of instant noodles.

The two little comrades of the Criminal Investigation Brigade with instant noodle bowls couldn't care about instant noodles when they saw Su Nan coming: "Officer Su! ”

Su Nan hurriedly entered the door and said, "What about the evidence?" ”

"In this USB stick!" One of them touched his pocket and handed a small USB flash drive to Su Nan.

After taking the USB flash drive, I went to turn on the computer, and did not forget to tell the two people: "You eat yours, but there is nothing to do tonight, you eat less, and you will go home and eat something good later." ”

"Hehe, I don't have a wife, and I don't eat instant noodles when I go home."

"It's just, it's all the same."

The two of them sat next to Su Nan with instant noodles in their hands, sucking in the instant noodle bowl, waiting for Su Nan's computer to turn on.

"Officer Su, have you eaten?"

"Eat." Although the food at my brother's house is not very good, and I don't eat much, it is better than eating instant noodles.

The two glanced at each other meaningfully, and deliberately dragged out their voices: "Officer Su can also cook?" I can't see it! ”

Su Nan smiled reluctantly: "I won't, even if I make it, it's hard to eat." ”

"Then your husband is really a model for supporting the police, so that our police officer Su can avoid worries while enforcing the law!"

Although Fang Jincheng also cooks, she doesn't do much, but her skills are really good, which makes her very puzzling.

The computer turned on, and the two of them snorted and ate instant noodles while watching Su Nan plug in the USB flash drive and open the folder.

One of them said: "This is a video of the shop downstairs in the square, a clothing store, right next door to the post office, the store has been burglarized before, so the video is usually kept for a long time." ”

There were two videos in the folder, both from a month ago, and on the day the video was deposited at the post office, there was only a difference of more than 20 minutes between the two videos.

Su Nan opened the first video, and a handsome young man appeared in the picture, and the little girl at the door of the clothing store warmly beckoned the young man to enter the store to see the latest style that had just arrived.

The young man in the baseball cap raised his face to look at the little girl, smiled and waved his hand, and a document bag in his hand flickered by, and the camera also captured his front just right.

The little girl still didn't seem to give up, and deliberately teased two sentences, and it was impossible to know what she was talking about.

After the young man refused, he entered the post office next door, and the little girl looked excitedly into the post office for a long time.

The second video is more than 20 minutes apart from the picture of the young man coming out of the post office, and the little girl at the door of the clothing store has also changed from one to three, all waiting for it.

Seeing the handsome guy appear, they hugged up, pushed and pulled, and coaxed people into the clothing store, and it didn't take long for the handsome guy to break free from the entangled beauties and escape, a few beauties didn't look like selling clothes at all, more like teasing the handsome guy, and chased them out.

"It's a coincidence, these recognized Su Chen's photo as soon as they saw it." After eating the last bite of instant noodles, the little policeman's face was flushed with spicy water, and he drank two sips of water while saying to Su Nan: "As soon as I saw the photo, I said I knew him!" I felt that things were not simple at the time, and after asking two sentences, I actually took out my mobile phone to show me, and guess what, Su Chen's photo turned out to be her mobile phone desktop! ”

"Ahem!" Su Nan didn't eat instant noodles but almost choked on his own saliva, although this Su Chen is quite handsome, but he is not a star in the end, there are still people who like to use his photos as mobile phone desktops, this is really a bit of a nymphomaniac......

"I asked her where the photo came from, and she said that it was taken secretly, and I said when it was taken secretly, and I said when it was taken secretly, and I said that you remember it accurately? Is there anyone else to testify? She originally wanted to ask the little sister to testify, but she remembered that there was a surveillance video in the store! ”

With this surveillance video as evidence, Su Nan can basically be sure that the person who sent her these videos is Su Chen himself.

The phone should be stationary when the two of them are in bed, so the recording is ceiling and only sound.

When Luna concocted the 'poison', the person who secretly recorded the video was likely to be Su Chen.

Thinking of this, Su Nan basically knew it in his heart.

After going around in a big circle, it turned out that Su Chen was the direct person who caused this incident.

He had been ready to send evidence a month earlier, why he could have been sure that Luna would be suspicious, because he was the hand that moved things forward.

It's no coincidence that he was arrested, he sent it to the door himself, just so that the police could continue to work on the case.

Su Nan felt a little scary, if all this was really as she guessed, then how strong Su Chen's heart was, and he spent his heart and energy to complete this matter.

"Officer Su, is there anything else we need to do?" From the beginning of Su Nan's reverse thinking to find the suspect, they were a little impressed by Su Nan, who was worthy of being the junior sister of Team Xu, and couldn't help but have more respect.

Su Nan shook his head: "It's nothing, you guys hurry home, there is no arrangement for duty tonight, right?" ”

"No, then we'll go back."

"Okay, bye-bye."

"See you tomorrow, you should go back and rest early."

"Okay."

After the two left, only she and two colleagues on duty were left in the office, the temperature was low at night, and the air conditioner had been turned off, but the fan was still sparing no effort, whirring and blowing.

Su Nan sat in front of the computer and fell into deep thought, whenever she encountered a bottleneck, she was good at reverse guessing.

Su Chen sent these two pieces of evidence to convict Luna, but it was not clear from the video what the relationship between the two was.

But these two videos can't directly convict Luna, and besides, didn't the forensic department say that the videos were spliced and fake.

If the video alone can't convict Luna, will Su Chen provide other evidence, even evidence about the ergoline virus?

But when Su Chen slowly sent the evidence in front of him, it would be too insulting to the Criminal Investigation Department.

After thinking about it, Su Nan copied the backup video sent by Su Chen into the USB flash drive of the computer.

Unplugged the USB flash drive and went straight to the identification department, the section chief was there during the day, and she didn't give her a good face, she came over to touch the tone, hoping that the person who was not good at talking would not be on duty tonight.

Her prayer may have been known to the heavens, and there was only one 'white coat' on duty in the office of the Identification Section.

Although he was wearing a white coat, he was also making up the police, and when he saw Su Nan coming over, he couldn't help but be vigilant: "It's a big night, there is a shortage of manpower, and some appraisals can't be done, so I have to wait for tomorrow." ”

Su Nan didn't think it was pestle: "I just want you to help me watch this video." ”

The white coat took the USB flash drive and looked at it, and then inserted the USB flash drive into the computer.

Su Nan explained on the side: "This is a piece of evidence I received, because the original has been destroyed in the process of identification, so I will show you a copy." ”

"It's okay, the original you receive may not be the original." The white coat yawned lazily and clicked play.

Su Nan has watched the video several times, and he can recite what they want to say one by one with his eyes closed.

The white coat first looked casually, and then approached the computer to take a closer look.

After watching it for a few seconds, I pressed the pause button: "This video, I also participated in the appraisal when I was doing it." ”

Su Nan's heart was cold, it was over, he thought that he would just avoid the section chief, but he didn't think that there would be people involved in the appraisal.

Since I have already done an appraisal during the day, I definitely don't want to do it again now, and I will stick to my original appraisal results.

When he was thinking about what to say to let him continue watching, the other party squinted at the video: "Like this, but not this, the one we got is more like it was destroyed." ”

After that, he clicked the play button, and the video continued to play.

After a short broadcast, he affirmed again: "The film we identified has been artificially processed, and great traces can be seen, which cannot be compared with the smoothness of this short film." ”

Su Nan couldn't help but be happy in his heart, and a trembling big stone finally landed, but at the same time, he was a little puzzled while breathing a sigh of relief: "Destruction?" Traces of human processing? That's the original.,Could it be that there's a problem with the U disk storage reading? ”

The other party shook his head: "It's not, but the film is no longer with us, and we can't compare and watch it anymore." ”

"Don't you have a backup?"

"Confidentiality clause, no backup." The white coat rolled her eyes at Su Nan, as if she was a little helpless about her ignorance.

Su Nan remembered what Ah Zhi told her before, saying that the video was damaged during the identification process, and she asked again: "Could it be damaged during the identification process?" ”

"It's not that there is no possibility, it's just that I was one of the first people to watch this video, and the first time I played it, I could see that there was a problem without identification, and there was no change after the final identification, so there was no such thing as damage to the identification process."

Su Nan's heart was cold, and he already thought of Xu Zirui.

The person who sent the video was Xu Zirui, and only he had the opportunity to do it, but why did he do it, and for what purpose?

To keep Luna? Could it be that he deliberately let Luna go to the airport in the first place?

Once some questions are delved into, embarrassing realities and answers will appear in front of you in front of you.

"Do you still have to do an appraisal for this film?"

Su Nan was stunned for a moment, and then nodded: "Yes, can you get a result tonight?" ”

"It's not a big problem, I'm on duty tonight, I'll make it for you, and you'll be on duty tonight?"

Su Nan nodded, I just don't want to go home tonight, it's better to be on duty at the city bureau, think about how to face Fang Jincheng and Su Su in the future, and the life I want to go in the future.

"Nacheng, when you come over after twelve o'clock, the result should come out."

Su Nan breathed a sigh of relief, if the previous identification result was due to video damage, then this time it should be able to produce a serious result.

"Okay, you must help me identify it carefully."

"Don't worry, if even we are cheating, how can you solve the case."

Su Nan smiled with relief, but agreed very much.
