Special case investigation team V

Cheng Jin and Yang Simi walked to the place surrounded by everyone, Ye Lai and the others pushed aside to make room for them.Cheng Jin saw a man in camouflage uniform holding a large toy-like plane in the open space among the crowd, and his comrades beside him were half kneeling on the ground and manipulating a piece of equipment.

Seeing the plane, Cheng Jin knew why Li Hui said that the military equipment was different.

Compared with the civilian drones, the military drones brought by the armed police are very different in appearance. The general civilian drones have many legs, like iron bugs, but this military drone is a small plane. It looks like it has no feet and only wings, like a minimalist model airplane—an old-fashioned airplane.

Cheng Jin thought, it doesn't matter what you look like, the key is to be able to work.

After watching the drone, everyone went to a meeting to discuss how to find the dead body.

The content of the meeting was mainly that the Public Security Bureau put forward various needs, and the armed police who came to provide assistance would find ways to achieve their goals for them. Of course, the armed police would directly reject unreasonable requests.

After the two sides discussed the process of searching for the dead bodies, Li Hui took a few people to the Gobi with the armed police, and Han Bin and You Duo followed.

Xiaoan also wanted to go, she wanted to play with drones, but after staring at those drones for a while, she still went to do her own work honestly - together with Ye Lai, count who is familiar with Yun Shu The terrain of the Gobi Desert.

Bu Huan's job is to visit those people - those counted by Xiao An and Ye Lai, to see if they have seen anything, or to see if they have any problems.He called a few criminal police officers from the Yunshu Public Security Bureau to assist him. They decided to "surge" his colleagues in the government department, that is, border guards, forest guards, etc., not specifically targeting them, but because the government department is the most standardized check.As for those folk groups or individuals, Ye Lai and the others are still counting, so there is no rush.

Cheng Jin assigned himself the task of meeting the family members of the victim, together with Yang Simi.In order to prevent the problem of poor language communication, Oman was specially brought along.

They were going to meet the parents of the boy who disappeared half a year ago. When they contacted each other, they were very positive that they were free at any time.

In contrast, when the family members of the other two victims who were identified were contacted, their responses were lukewarm.When Cheng Jin asked when they were free to meet, they hesitated, and finally, under Cheng Jin's questioning, they chose to meet at night.Cheng Jin made an appointment with them for a specific time, one would meet earlier and the other later.

The boy who disappeared half a year ago was called Mai Sumu, he was not of Han ethnicity, but his parents spoke Mandarin well, so there was no obstacle for him to communicate with Cheng Jin and the others.

Mai Sumu's parents are very haggard. Their actual age is only in their 40s, but they look like they are in their 5s or 60s.They are eager to know if the case has progressed.

Cheng Jin could only tell them regretfully that they hadn't yet.

They are disappointed.

In the ensuing conversation, Mai Sumu's father expressed his conjecture: "I still think that the day my son disappeared, he should have been to an Internet cafe."

Cheng Jin said: "Isn't he still underage?"

You need to swipe your ID card to go to an Internet cafe, and minors will be turned away.

Mai Sumu's father said: "I heard that there is a spare ID card in the Internet cafe. If you are under the age, you can use the spare ID card." He went to research it.

Cheng Jin nodded. It's always like this. The Tao is one foot tall and the devil is one foot high. There are policies on the top and countermeasures on the bottom. "Why do you think he might have been to an Internet cafe that day?"

"I think every day, where did he go that day, who did he meet, who did he go with... Then I thought that he likes to play computer games and has a computer at home, but we will control the time he plays, there is no way If he plays at home, he goes out to play."

Mai Sumu's father said eagerly: "I asked his friends, and they admitted that they often go online together, usually during non-weekends, when they eat at noon, or after school in the afternoon, they go to play for a while. On the day he disappeared, I also played with my friends—they played online together, and his friend said he was also online, and halfway through he said he was going to change computers, but he didn’t go online again.”

Cheng Jin said: "Have you told the people in the Public Security Bureau about this information?"

Oman next to him frowned and recalled.

Mai Sumu's father said: "I said it before, but you said that this clue is useless. It seems to say that the camera recordings are only kept for one month, and those that exceed one month will be automatically deleted. However, you should have a way to see the deleted ones. Was it a video? As long as you see the video, you can know who my son had contact with that day, and you can know who killed him!"

Aman moved closer to Cheng Jin, and said in a low voice: "There are two Internet cafes nearby—he's not sure which one his son went to surf the Internet. I have the impression of going to an Internet cafe, and the camera recordings of these two Internet cafes are only kept for one month." He glanced at Mai Sumu's father, "It has been more than a month since he told us, so the video cannot be found."

Cheng Jin nodded, looked at Mai Sumu's father, and said, "It should be true that the Internet cafe said that the video has been deleted. I will ask someone to check, but there is little hope of finding the video. Besides, I don't know if you have He said that when he wanted to change a computer, he might have left the Internet cafe, for example, went shopping or had other temporary business, and then disappeared outside the Internet cafe. What will be photographed."

"It's just your guess." Mai Sumu's father didn't want to give up on this direction.

Cheng Jin said, "Is your home computer still there?"

"Yes, yes..." But what do you want to do?

"I'll ask someone to come over and check. You should be able to find your son's game account. As long as you have an account, you can find out where he has been online. If he did go to an Internet cafe on the day he disappeared, then we will go to the Internet cafe." Let's see if we can find any clues."

Mai Sumu's father nodded quickly, "Okay, okay."

Cheng Jin called Xiaoan to come over.

After more than 20 minutes, a criminal policeman from the Public Security Bureau brought Xiaoan over.

"Boss, Teacher Yang!" Xiao An first smiled at Cheng Jin and Yang Simi, then glanced around, "Where's the computer?"

Mai Sumu's father was very surprised, just such a little girl?Can she do it? "Here." He led everyone to the study.

Xiaoan turned on Mai Sumu's computer, first confirmed Mai Sumu's game account name, and then contacted the game company, asking them to pass over the relevant data.Not long after, she said, "I found it, boss, the last time he went online was at Hongxing Internet Cafe, that day was..." She reported the date and time to Cheng Jin.

Mai Sumu's father was very excited, "That's right, he just happened today, so he went to this Internet cafe...then let's go to the Internet cafe now?"

Cheng Jin nodded.

"Wait a minute." Xiao An tapped the keyboard quickly, packing a lot of information from Mai Sumu's computer and sending it to his own computer. Check it later, maybe he can find some clues. "Okay, let's go!"

Hongxing Internet Cafe is not far from Mai Sumu's home. Cheng Jin showed Mai Sumu's photo to the Internet cafe's network administrator, and the other party said without blinking that he did not remember this person.

Cheng Jin said: "Take a closer look?" As for regular customers, you can always see something familiar, right?

Yang Simi raised one corner of his mouth lazily, "Why are you being polite to him, take him back to the Public Security Bureau." He raised his chin slightly towards Aman, "Handcuffs."

"..." Oman touched the handcuffs around his waist.

The webmaster’s face turned pale with fright, and he hesitated to admit that Mai Sumu had indeed come to them to surf the Internet, using the “fake” ID card provided by the Internet cafe—he said that this was the reason why he didn’t know Mai Sumu, because the Internet cafe It's against the law. They bought hundreds of ID cards with authentic information from special channels, and specially provided them to children who are underage.

Although he admitted that he knew Mai Sumu, the network administrator said that he really had no memory of when he came here for the last time, whether anything happened that day, how he left later, and who he left with.

"Which ID card did Mai Sumu use that day?" Xiao An asked.

"I don't know... There are guests coming. If I don't have an ID card, then I will just draw an ID card and enter it into the system." The ID card entry records are all there, but there are many children who come to the Internet every day, so there is no difference at all. It is not clear who used which ID.

"Let me take a look." Xiaoan connected to the server of the Internet cafe, because she knew the time when Mai Sumu played games that day, so she looked for the corresponding Internet user according to this time, and soon, she found the one that best suited her, " It should be this.” At that time, the network administrator entered Mai Sumu’s identity information as a man in his 50s, and the system records showed that he was sitting in seat E15.

Everyone went to the side of the seat to have a look, and the camera could capture it.

Net Pipeline: "The videos are only kept for the last month."

"You'll have to read it to find out. Where is the hard drive?" Xiao An asked.

"You come with me."

After getting the hard disk, Xiaoan connected it to his computer, checked the information inside, and said to Cheng Jin and the others: "The data stored in the hard disk is in the form of overwriting, and the new data overwrites the old data that has expired. If we If we are lucky enough, what we are looking for may not have been covered, so we can find a way to get it out."

They were lucky. An hour later, Xiaoan actually found a video of Mai Sumu's disappearance. However, there was only a video of him entering the Internet cafe, not when he left. It's a pity.

"..."

Mai Sumu's father begged: "If you look for it again, maybe you will find it again?"

Xiao An looked at Cheng Jin.

Cheng Jin patted her head and said softly, "Try again."

"Okay." Xiao An searched again, then shook her head silently.

Cheng Jin looked at Mai Sumu's father, "Let's think of other ways."

"... What else can I do?" Mai Sumu's father was desperate.

"First take the photo of Maisumu and ask the nearby residents to see if anyone has seen anything." However, too much time has passed, and the hope is slim, but it is also a direction of investigation. "Aman, call some people over to help."

"okay."

Hope rekindled in Mai Sumu's father's eyes.

Cheng Jin said to him, "Go back first."

"I want to help too, can I?"

It's not even classified detective work.Cheng Jin nodded, "Yes."

"Thank you."
