The signal coverage range of the signal tower in the north of the city is 600 meters. Within a 600-meter radius of the signal tower, there is an urban village and two residential areas, as well as some shops along the street. It seems harder to find someone in such a range than to reach the sky.
The staff at the Skynet Control Center are busy. There is only one road from Heshi Township into the Beiguan area of the county. There are five cameras of the surveillance system on this road. The staff input Zhu Jun's photos into the system, and the computer is working on this.
Look for traces of Zhu Jun in the videos recorded by five cameras.
With a "beep" sound, the system's search was suddenly interrupted, and a picture popped up on the big screen. What appeared on the picture was a car, and sitting in the passenger seat of the car was Zhu Jun. From the video, it can be seen that the car drove into the city
The road between Zhongcun and Futai Community. Later, during the surveillance at the entrance of Futai Community, it was discovered that Zhu Jun got off the car at the entrance of the community and entered the interior of Futai Community.
Futai Community is an old community built in the last century. The monitoring system in the community is not connected to the Internet. He Xiaohui and the others immediately drove to Futai Community.
There are three entrances and exits in Futai Community, and there is no guard on duty at the entrance. He Xiaohui contacted the local police and set up hidden sentries at the three entrances. When Zhu Jun was found, he immediately arrested him.
The monitoring room of the community is very simple. There are 12 cameras installed in the whole community, 7 of which are broken. From the running cameras, it was found that after Zhu Jun entered the community, he turned into the area of Buildings 8 and 9, and these two
The cameras in front of each building are all broken.
"We have no choice but to find these." The technician said helplessly, shaking his head.
"It doesn't matter, at least we can locate Zhu Jun currently on these two floors." He Xiaohui patted the technician on the shoulder and said:
"You continue to watch the video later and see if Zhu Jun goes out again."
"Captain Zhang." He Xiaohui turned to Captain Zhang of the Shangdong County Criminal Police Brigade who was standing behind him and said:
"Please arrange for two plainclothes officers to keep an eye on each corridor entrance. If Zhu Jun comes out, he will be arrested immediately."
"Okay, I'll make arrangements right away." Captain Zhang responded and walked out of the monitoring room.
"Team He, what's our next move?" Zhang Pengfei asked.
"Both buildings are six-story buildings with two units. There are 24 households on each floor, and there are 48 households in the two buildings. It is difficult to investigate these 48 households in a short period of time." Su Le
explain.
"How about we simply seal off the two buildings and conduct inspections one by one," Zhang Pengfei said.
"No, it's already late at night, and the residents are all sleeping. It's too disturbing to knock on doors one by one. This method should not be used unless it is absolutely necessary," He Xiaohui said.
"Then what should we do? Should we just wait like this?" Zhang Pengfei said anxiously.
"Think about it again and don't worry. If Zhu Jun is really inside, he won't be able to escape," He Xiaohui said.
"Hey, stop, stop, stop." Dr. Qiao, who was watching the video with the technicians, suddenly shouted. Everyone heard the shout and quickly gathered around.
"Go back and play it again." Dr. Qiao said.
The video shows that at 6:10 p.m., a delivery man rode a tram into the area of Building 8 and Building 9.
"In this kind of old residential building, there shouldn't be many people ordering takeout. We can check which room the takeout is delivered to," Dr. Qiao said.
"Okay, contact the platform immediately."
Half an hour later, it was found from the records of the takeout platform that someone ordered takeout at 5:45 pm. The delivery address was Room 201, Unit 2, Building 8, and the takeout was signed for at 6:12.
After arranging arrests in front of and behind the building, He Xiaohui and the others quietly came to the door of Room 201. Seeing that there was a door mirror on the entrance door, He Xiaohui arranged for everyone else to hide where the door mirror could not see them.
I came to the door of Room 201 alone.
The dull knocking sound of "bang bang bang" sounded extremely harsh in the middle of the night.
"Bang bang bang"
"Bang bang bang"
There was never a response from the door.
He Xiaohui took out her cell phone and dialed Zhu Jun's number, then put her ear against the door and listened carefully. A faint cell phone ringing sound came from the room, but no one answered the call.
He Xiaohui signaled the armed police to break down the door.
Ten minutes later, the door was opened. He Xiaohui and the others immediately smelled a strong smell of blood when they entered the house. After turning on the lights, they found that there were two corpses in the room. One was lying on the sofa in the living room, and the other was lying on the floor in the kitchen. In the living room
The kitchen was full of blood, and there was almost no place for anyone to put their feet. Lying on the kitchen floor was the Zhu Jun they were looking for.
Except for Dr. Qiao, everyone else retreated to the corridor. Technical personnel from the county criminal police brigade rushed to the scene to cooperate with Dr. Qiao's work.
Due to a vicious criminal case in Shangdong County, Jiangbei Provincial Criminal Police Corps also sent people to the scene overnight to assist in the investigation. He Xiaohui also reported the situation in Shangdong to his superiors as soon as possible. After a night of communication between the police systems of the two provinces,
After coordination, it was decided that the case would continue to be investigated by Jiangnan Province, with personnel from Shangdong Police and Jiangbei Criminal Police Corps fully cooperating in the work.
Shangdong County Police Department. He Xiaohui's colleagues, Captain Zhang of the Shangdong County Criminal Police Brigade, and Yu Xueming, deputy director of the Jiangbei Province Major Cases Division, are listening to Dr. Qiao's on-site investigation report.
"After investigation, the deceased were Zhu Jun and Zhu Jun's cousin Zhu Dongxiao. Both of them were killed by cutting their carotid arteries with a sharp weapon. The murderer's method of murder was very clean and neat, killing with one knife, without any sloppiness. The murderer was not only sophisticated in his techniques, but also understood anatomy.
Very knowledgeable and has a very good grasp of the location of the carotid artery.”
"It seems that the murderer we encountered this time is unusual." Director Yu said in a low voice.
"Judging from the coagulation of the blood at the scene, the extent of the corpse spots and the degree of rigor mortis, the victim's time of death should be between 8 p.m. and 9 p.m."
"The murderer's movements were fast enough." He Xiaohui sighed.
"Based on the condition of the body lying on the ground, the direction of the blood spatter and the location of death, the murderer should have been standing with the victim in the living room talking after entering the house. The murderer suddenly attacked Zhu Dongxiao. When Zhu Jun saw that the situation was not good, he thought
Get a knife from the kitchen. Before Zhu Jun could get the knife, the murderer had already cut his carotid artery."
"To be able to kill two people instantly, the murderer must have received professional training." Captain Zhang said.
"There are no valuable fingerprints, hair or clues left at the scene. Judging from the height of the victim and the appearance of the wounds, the murderer should be over 1.7 meters tall."
"Is there anything else that needs to be added?" He Xiaohui asked.
"No, we can only get this information at the moment."
"Director Yu, Captain Zhang, what are your instructions?" He Xiaohui asked.
"After listening to Dr. Qiao's analysis, it seems that this murderer is a professionally trained professional killer. The opponent we face this time is not simple. Captain He, we have nothing to add here. You just give the order. Go up
The East Police are fully cooperating," Director Yu said.
"Okay. At present, we don't have any traceable clues about the murderer. We can only start from the surveillance video and check all the surveillance cameras around Futai Community to see if we can find any clues about the murderer."
On the Shangdong side, the investigation of the surveillance videos around Futai Community is in full swing. On the Zhongjiang side, Deng Ru and Ding Yiran are also intensively investigating Zhu Jun.
The place Zhu Jun rented in Zhongjiang was a one-bedroom and one-living room on the top floor of an old four-story building. After finding the landlord and opening the door, he found that the room was in a mess, with garbage on the floor and coffee table. The bed was full of garbage.
The bedding was spread out randomly. After a careful search of the room, it was found that there were almost no valuables in the room, and the closet was empty without a single piece of clothing. It seemed that Zhu Jun had no intention of coming back when he left.
Among the scattered food packaging bags on the coffee table, Deng Ru found a discount card for an Internet cafe. In this era of mobile Internet access, almost all Internet cafes in the city have been wiped out, with only a few remaining that mainly play large-scale online games.
The Internet cafe is still operating. Is this Zhu Jun still a game fan? Deng Ru thought.
The Internet cafe on the discount card was not far from where Zhu Jun lived, so Deng Ru and Ding Yiran drove there to find out if Zhu Jun had any acquaintances in the Internet cafe.
This is a very high-end Internet cafe. The indoor air conditioner is turned on very well, and the computer monitors are all 32-inch high-frequency monitors. The rows are very spectacular. When the owner of the Internet cafe saw Deng Ru and Ding Yiran coming in,
I immediately judged that these two people were definitely not here to play games, so I immediately walked up to them and asked:
"Are you two looking for someone?"
"Yes, find someone."
"who are you looking for?"
Deng Ru handed Zhu Jun's photo to the owner of the Internet cafe. The boss took one look and immediately said to Deng Ru:
"Impressed."
Deng Ru took out his ID and showed it to the Internet cafe owner, asking him to tell him what he knew about Zhu Jun.
"This guy is quite weird, that's why I have an impression of him. People come to my store just to play games and experience the pleasure of using our high-end equipment to play games. But this guy is not here to play games, he is here.
Go to QQ. Nowadays, no one has to find a computer to access QQ. You can just use your mobile phone.”
"Does he come here often for QQ?"
"I don't come here very often. I just came a few times some time ago, but I haven't come recently."
"Oh, so that's it. Then which machine did he use qq on?"
"Over there, that one in the corner, the monitor frequency of that machine is low and no one usually uses it. I thought he was here to log in to QQ, so I kept letting him use that one." The boss led Deng Ru and Ding Yiran.
I walked to the machine in the corner and turned on the computer.
Ding Yiran sat on the computer chair and opened the QQ program. A QQ number appeared on the QQ login interface. He clicked on the small arrow next to the number. No other numbers were recorded. It seems that this computer has only logged in with this number recently.
The login password field under the .qq number is blank. It seems that the person logging in to qq has not set a password to remember.
"Will the computers here set up QQ to automatically clear chat records when offline?" Ding Yiran asked.
"Yes, the computers in our Internet cafes will be set up like this to avoid unnecessary trouble." the boss replied.
"Can the chat history be restored?"
"I've heard others say that they can recover, but I can't."
"Can we borrow this computer?"
"Okay, okay, you can just take it. No one is using this computer anyway." The boss agreed readily.
Although the boss did not ask for it, Deng Ru still wrote an IOU and left her contact information with the Internet cafe owner, promising to send it back to him as soon as he used it.
After returning to the bureau, Deng Ru and the others immediately handed over the computer to the technicians, hoping that they could crack the QQ login password and find the previous chat records.
