Replace the evil way

Among the evidence brought back from the mansion, there is one thing missing in the information society-the mobile phone.It's not that I didn't find it, but when I found it, the screen was damaged and couldn't be turned on. It was handed over to a technician who is proficient in electronic products at the technical investigation for repair.

At this moment in the dead of night, there will never be a shortage of people working overtime in the bureau, and a light is on in the technical detective's office.Cheng Zesheng leaned against the door frame, and tapped his fingers on the door panel, making two crisp sounds of "Du, Du".

The desk with the light on is the one at the back. The man looked up and saw Cheng Zesheng, and said hello: "Brother Cheng, you haven't returned so late?"

"You've been working overtime to help us restore the criminal investigation data. I don't have the nerve to go back first." Cheng Zesheng walked in with a cup of coffee, "How's it going, Xiao Chen?"

"Hey, it's not good yet. I've squeezed time in the past two days to do a little bit of bits and pieces. Isn't this recently helping the head of the Economic Investigation Team to watch the money laundering case? Good guys, a few underground casinos, monitoring their communications, Each of our teams is in charge of one, and we have been on shift for a week!" Xiao Chen's desk is full of mobile phone parts, "It's just me going back to rest today, so I hurried back to the office to repair the mobile phone."

"It's been hard work," Cheng Zesheng handed him the coffee, "Don't be disgusted with the cafeteria, I'll invite you to the coffee shop after my brother's case is over."

"Thank you, Brother Cheng." Xiao Chen chuckled and plugged in the stirring stick, "Just to refresh me, don't worry, it doesn't matter if the phone can't be turned on, as long as the font chip can be read, I just got it down here, except for the glue and the computer. OK."

Cheng Zesheng pulled up a chair and sat down, chatting with him about recent work and gossip in the bureau.After tinkering for a while, Xiao Chen put the font chip on the device to extract the image, then restored the data, and snapped his fingers: "Brother Cheng, come and see, you can find everything you want."

"Are all the records there?" Cheng Zesheng bent down and looked at the screen. "It's mainly the records of calls, messages, and communication software. Call them up and show me."

"The caller is here," Xiao Chen clicked to open a folder, "but the address book can't be matched, only the number can be seen."

"Having a number is enough, can I check it now?"

"Yes, we have a rich network system now, and we can check the registration information. Unlike before, we have to go to the operator's place." Xiao Chen clicked on the internal software and entered the number, "Eh? Empty number. "

Among the exported communication numbers, all of them are empty numbers after checking.

Xiao Chen felt baffled, looked up at Cheng Zesheng, and found that his brows were deeply wrinkled, and his handsome cheeks were covered with dark clouds.He whispered: "Look at the exported information and chat software records."

Xiao Chen opened them one by one, and found that the exported data were all garbled characters. He plugged and unplugged the font chip several times to confirm that there was no problem with reading, only the exported data was wrong.He stared at the font chip and muttered to himself: "It doesn't make sense, if it is damaged, it can't be read at all... What's going on?"

Cheng Zesheng remained silent, and clicked on the "Photo" file. There was only one photo in the entire folder. After clicking on it, it was a musical notation with only one line written on it.

175235126521

其中1和7、6和5上面有半括号相连，2和3、1和2、2和1有下划线相连，两个5上面有圆点，程泽生摸着下巴，他天生五音不全，也想不出这想表达的是什么。

"What is this? The deceased was still playing music?" Xiao Chen asked.

"I don't know, I'll ask someone who understands music tomorrow." Cheng Zesheng looked at all the documents and confirmed that the entire font chip had nothing of value except for this photo and a bunch of empty numbers.

He promised to help people restore the data, but the matter has not been completed yet, Xiao Chen scratched his short hair embarrassedly: "Brother Cheng, let me put this chip here for now, and I will study it later. Electronic gadgets are uncertain, maybe in a couple of weeks." The day will be fine, those empty numbers may also be a data problem."

Cheng Zesheng patted him on the shoulder: "No rush, no rush, I feel sorry for you taking the time to help. Of course it's best to recover, and don't feel pressured if you can't. We don't do criminal investigation for nothing. Those old seniors in the past were not as talented. Isn’t technology still solving crimes?”

Today, all he found was bad news. Cheng Zesheng was driving the car, still thinking about this seemingly simple but foggy case.It was obvious that only one person died, but the mystery behind the investigation was one after another. The key is that the evidence you have can't even convince you, how can you convince others?

His car drove into the compound of the military area. The sentry at the gate looked at the license plate, and the son of Chief of Staff Cheng saluted and let him go.Cheng Zesheng entered the house lightly, for fear of waking up his parents, but just as the door closed, a deep voice sounded in the darkness: "Are you back?"

"...Well," Cheng Zesheng turned on the light with a snap, "Dad, are you still asleep?"

"You won't be home for a few days, I'm afraid Xiao Huang will bring me a wooden box."

"……"here we go again.As soon as Cheng Zesheng looked up, he saw a photo of a family of four hanging on the wall. He and Cheng Zhenqing stood with their arms around their shoulders. Both of them were wearing formal police uniforms, and their young smiling faces were full of youthfulness.

"Don't put pressure on the provincial department, I won't go there." Cheng Zesheng lightly changed his shoes and entered the house, "Oh, and, I will move to the dormitory in two days, which is closer to the bureau than our home. "

After finishing speaking, he didn't bother to look at his father's face, and went upstairs to sleep.

In the crowded and small office, Cheng Zesheng and Xiang Yang surrounded the security guards, waiting to retrieve the surveillance video from April 4th to 13th.

The house that He Wei rented was in the old city, an old community built in the 90s. There was no special property management, let alone monitoring.It wasn't until last year that the street responded to the government's call and allocated funds for a comprehensive rectification, that the surveillance cameras were installed in each old community, and a security booth was specially set up.

However, there are only three monitoring probes installed at each door in this community, and there are no other probes in the community, so it can only be judged when He Wei entered the community, and it is not known whether he has returned home or not.

In the color surveillance screen, the first time I saw He Wei was at 13 pm on the 6th, when he came back from work with vegetables in his hand; the second time I saw He Wei was around 9 pm, when he changed into a casual He pretended to go out, and then the surveillance kept fast-forwarding. At about 12 o'clock, He Wei appeared on the screen again, and he came back.

He walked very slowly, wobbly, as if he was really drunk, and he stopped by the tree and fumbled for something in his pocket.At this time, He Wei suddenly raised his head, his well-featured face was facing the camera, and his eyes suddenly became sharp, without any hint of drunkenness.

Cheng Zesheng quickly pressed pause and zoomed in on the screen.The image quality of the cheap camera is not clear. After zooming in, the face becomes an outline composed of pixels. He zooms out again, takes out the phone to find the photo of the dead body, and compares it repeatedly with the screen before saying, "That's not right."

"Huh?" Xiang Yang stared at the screen and the phone for a long time, but couldn't see any difference, so he humbly asked for advice, "What's wrong?"

"It's wrong from head to toe. The shirts are the same color, but one has stripes on the cuffs and neckline, and the other doesn't; the pants have different belt buckles; the shoes are also wrong, although they are all blue and white, but one is AJ11 North Carolina. Blue, one is the AJ11 Blue Snake, and the upper of the Blue Snake has a snakeskin-like pattern." Cheng Zesheng put the photo next to the surveillance image, "Do you see it?"

Xiang Yang rubbed his eyes, stared at it for a long time, then nodded in a daze: "...it seems so."

"It seems like it is."

Xiang Yang's eyes were glued to the screen, almost staring out: "I can't tell if there is a mole under the eyes, but it should not be He Lu, his alibi is sufficient, and he is in a hotel in another city with his colleagues during this period of time rest."

"I was indeed wondering if this person was He Wei, but I didn't doubt whether he was He Lu."

Xiang Yang was stunned again, what does this mean?Deputy Cheng's words became more and more inscrutable, and he almost couldn't understand the proposition.He asked cautiously: "It's also possible that you went out and changed a set of clothes?"

"Then it's intriguing to think about what he does when he goes out." Cheng Zesheng looked at the security guard, "Is there any other places in your community where you can enter and exit besides the main entrance?"

"There is a broken railing near the south gate, and there is a vegetable market behind it. Many elderly people go out to buy vegetables through that railing for convenience."

The security guard led them there together, only to see people coming and going at this exit, and even valuable clues had already been destroyed.Xiang Yang observes this road, but there are two cigarette shops with probes installed, if He Wei walks from here, he might be photographed.

So Cheng Zesheng sent him to check the monitoring one by one, and he took the key to He Wei's house.This [-]-square-meter rental house is He Wei's home. It has one bedroom and one living room. The walls have turned yellow, and the roof is still partially cracked, but the inside of the house is clean and tidy.

Cheng Zesheng walked around the rental house. Although the sparrow is small, it has all the internal organs. The small kitchen of a few square meters is equipped with a coffee machine and a milk frother. It can be seen that although He Wei lives in a shabby room, he still lives a petty bourgeoisie.

Now my colleague came once and searched everything, but nothing of value was found.He Wei's interest circle and social circle are very narrow. From the books in his bookshelves and drawers, it can be seen that this person has an introverted personality, and his sexuality is also deeply hidden in the books. None of his parents and friends around him know about it.

But he often went to Avenoir, Cheng Zesheng guessed that it should be related to Lian Jingyuan.But even Jing Yuan also said that He Wei is very clean and self-conscious. Most of the time he comes to the bar to chat with him. In the bar, there are often people who like him and want to have a date, but He Wei refuses them all. Makes one wonder if it's sexual/frigid.

Then I opened the desk drawers and checked them one by one. I didn't find any books about music in He Wei's house, but I found that there were a lot of medicine in the drawers, not like an artist or a health care expert.Cheng Zesheng found the numbered musical notation dumped in his mobile phone, and compared it with the handwriting in He Wei's book, it felt like it was written by two people, especially the number "5", which He Wei used to connect together, so he didn't read it carefully The words are like an "8".

He put away his phone and continued to check at He Wei's home.Opening the closet, the clothes are not only monotonous in style, but also in three colors of black, white and gray. I don’t know if I want to imply that the mood of going to work is like going to the grave.Open the shoe cabinet, among the rows of black, white and gray leather shoes and sneakers, two pairs of colorful sneakers look very eye-catching, one pair of light green and bright yellow, and one pair of dark blue and dark red.

Cheng Zesheng took out the shoes, observed them for a few seconds and concluded that they must have been given by someone else.Moreover, He Wei didn't like this style and color, and had hardly worn it much. There was no difference between these two pairs of shoes and the new ones.He immediately thought of the pair of North Carolina blues, such a beautiful color must have been given by someone else, He Wei even put them on and went out, who is he going to meet?

He was squatting on the ground thinking, when the phone rang suddenly, it was Xiang Yang who called: "Deputy Cheng, He Wei was photographed at the cigarette shop, he came to buy cigarettes. But according to what you said, it might not be that 'He Wei', They still wear blue snakes on their feet."

"You said he bought cigarettes?" Cheng Zesheng stood up suddenly, went back to the desk and opened the third drawer, and found a bottle of budesonide formoterol powder inhaler from it.

"Xiangyang, ask the boss, how often does He Wei go to buy cigarettes?"

Xiang Yang asked the boss on the opposite side, and replied after a while: "He said he came to buy cigarettes when he saw He Wei for the first time, and he usually buys beer at most."

"Of course," Cheng Zesheng gripped the medicine bottle tightly, "He has allergic asthma, so of course he can't smoke."
