Gate of Mensa

The criminal police team was brightly lit in the early morning, and no one could sleep soundly until the murderer was caught.They must catch the murderer before he strikes again.Chen Guojun was smoking in the office and flipping through documents. Everyone in the big office was doing their own work. Su Yuyan was watching the video intently. Yang Jiaming was screening his personal social relations. Information, Ding Ran is watching the video surveillance video of Xiaoyue's house.

After fighting all night, everyone stared for a while at 5 o'clock in the morning. Su Yuyan woke up at 7 o'clock and went to buy some breakfast for everyone. While eating breakfast, Su Yuyan was thinking about the case.

Guo Nannan and Li Manli did not come to work until 8 o'clock in the morning and found out that they stayed up all night last night. After breakfast, everyone went to the conference room to hold a meeting.

Chen Guojun stayed up all night, and his complexion didn't look very good. Everyone knows that Chen Guojun is the one who is under the most pressure in this case. Every time there is a major event, he bears the pressure from above. The people below only investigate the case. He never scolds them. He seldom speaks harshly, and is a gentle captain.

Chen Guojun looked at the people, and then began to speak, "Okay, now we have a meeting, the murder case is broadcast live, and the case is formally registered as a serial murder case. Just now I have received the autopsy report of Xiaoyue Nu from the forensic doctor, which also contains hallucinogens. Composition, the two cases are now being investigated together, now let’s go over the two cases, let’s talk about it for you.”

Su Yuyan stood up and turned on the projector, "What you are seeing now are the photos of the corpses at the scene of the two live-broadcast murders. The time of the two murders was very close, and the methods were very similar. Now let's take a look at what they have in common. To summarize:

One is that the deceased were all live broadcast Internet celebrities, and they were female, young and beautiful, and had many fans;

The second is that the body of the deceased contained hallucinogenic ingredients, that is to say, the deceased killed himself by mistake in a state of unconsciousness, the big eater caused his internal organs to rupture and died, and Xiaoyue girl imitated a COS character and cut her with a dagger. Wrist, the item was swapped and she committed suicide, and the information on her online shopping item dagger has been found;

The third is that the scene was very clean, without the murderer's footprints and fingerprints. It is very likely that the murderer did not set foot in the room of the deceased before and after the crime, or he may have entered but destroyed the traces and hid it very well;

Fourth, the characteristics of live broadcast murder reflect the psychological characteristics of the murderer, seeking sensory stimulation and gaining the attention of the public. Expressing their twisted personalities unabashedly, they may think they're doing something meaningful.

Now we have to figure out a few things. The first is the drug, the source of the drug, the route of drug administration, and where is the drug residue?The people in the laboratory department took out all possible items from the garbage bins near the homes of Da Wei Wang and Xiao Yue, but the workload was very heavy, and the results were not available for a while. We had to find a breakthrough and narrow the scope of the search as soon as possible.

The second is the surveillance video. If the murderer wants to kill the victim, he must know the whereabouts of the deceased very well. In addition to the situation learned through the webcast, he must also have a good understanding of the offline living conditions of the deceased. Then the murderer must follow the deceased for a period of time to understand her. Whereabouts, then even though the murderer will intentionally avoid the camera, there must be something he didn't take into account. After all, the surveillance in some places is very hidden. We will check these hidden surveillance areas to reduce the workload.

Thirdly, the motive of the murder, this is the most important question at present, why did the murderer kill Big Stomach King and Little Yue Girl, what caused the murderer to be so indignant that he must kill them to vent his anger?Moreover, the murderer chose to live broadcast their death process with a strong sense of ritual. Does it indicate that the cause of their death is related to the live broadcast?After the murder, he didn't hide the body, didn't throw it away, and waited for the police to collect the body. What did he want to express?Did they deserve it?

Fourth, the conditions for killing. As we have analyzed before, the process of killing, so what kind of conditions should a murderer who meets these abilities possess?

One is that he can obtain drugs, so he may be an addict or work related to drugs, such as a hospital or a biochemical department;

The second is that he has quick thinking, strong anti-reconnaissance awareness, and certain medical knowledge. This drug is very powerful. If the dose is too large, it will cause obvious mental abnormalities. If it is used too little, it will not achieve the effect of mental hallucinations. We can see that the deceased did not have an obvious mental abnormal state during the live broadcast, but he was not very sober, similar to a half-drunk state;

The third is that neither of the two deceased showed signs of being sexually assaulted, so it is currently impossible to rule out whether the murderer was a man or a woman.

I compared the surveillance videos of the two incidents on the day of the incident. Yesterday, I saw Big Stomach King buying milk tea at the milk tea shop downstairs, and I found a detail," Su Yuyan zoomed in on the screenshot of the video .

"Look, everyone, the milk tea bought by Big Stomach King had yellow and blue striped straws when it came out of the milk tea shop, but when it arrived downstairs at her house, the straws turned into red and blue striped ones, because the taste of the milk tea has not changed, and the color of the straws is not very obvious. So the deceased didn't notice anything abnormal, but we can boldly guess that during the time when the milk tea shop was downstairs from the deceased, the deceased's milk tea was swapped, and the problem is likely to be in the swapped milk tea.

I went to the identification department to ask. The deceased was a milk tea bottle thrown in the trash can downstairs, but the milk tea bottle was not found at the scene. Apparently, the murderer followed the deceased at that time. After watching her drink the milk tea and discard the bottle, The milk tea bottle was destroyed.Therefore, the murderer may also be the murderer's accomplice, and must have appeared near the deceased's home that day.

Last night, I carefully compared the monitoring of people coming and going from various angles, and yesterday I also carefully observed the environment of the deceased’s house. If someone enters the vicinity of the deceased’s house, they must enter and exit this gate, and this gate has no dead ends.

When the murderer left the community after committing the crime, there were so many people coming and going, who could it be?I carefully watched the pictures of everyone who went out, and then I watched the surveillance footage downstairs of Xiaoyue's house. Xiaoyue's house is a high-end community, and access is stricter. How did the murderer drop the dagger?

I looked at the surveillance at the gate guard of Xiaoyue's female community from the time the dagger was received to the day of the incident. Fortunately, the amount of data was not large, and the result of the comparison was that this face appeared in the two communities at the same time? Su Yuyan opened two screenshots on the projector, two different cars, but the faces of the people in the cars were somewhat similar.

"It's hard for people to find the problem with different clothes and clothes, but there is one thing that betrays him, everyone look at this." Su Yuyan released the enlarged screenshot, which is the ring on the hand of the person on the car.

"Rings, you may think that there is nothing special. Many men wear rings, but please take a closer look. This is a limited edition couple ring designed by the famous French designer LEO. The domestic sales volume is very small. It just so happens that this person wear it.

As long as we find out who bought this pair of rings, and then screen and filter, I think there will be gains.In order to verify the results of my comparison, I fast-forwarded and watched the surveillance video of the big stomach king's activities near his home a week ago. I saw this picture on the surveillance 10 days before the incident.

This man also bought milk tea to get close to the big stomach king. He wanted to confirm the type of milk tea that the big stomach king bought. Look at his left hand, which also wears this ring, but he can't see his face clearly with the hat on. It can be basically confirmed that the man wearing the ring should have an intersection with these two cases.

Visually, he is about 1 meters tall, of medium build, male, and has certain financial strength.

We can go to the milk tea shop and the property office of the community to ask if we have seen this person and if we can do a portrait profile. Of course, it is unlikely to remember it, but we should try it.

In view of the fact that the two cases were accidents on the same live broadcast platform, I suggest to apply to the relevant departments to suspend the broadcast of the platform for a period of time to prevent further crimes in a short period of time and buy us some time.The report is over. "Su Yuyan sat down.

Everyone in the conference room looked up and listened carefully to Su Yuyan's analysis of the case. Everyone did not expect that Su Yuyan would check such a video with so much information, such a clear reasoning line of reasoning, and discover key details in one night. Even the precautions have been noticed, and I have to admire such a strong working ability in such a short period of time.

Everyone was digesting the case information that Su Yuyan had just analyzed, and Wang Jing suddenly applauded softly, "Yuyan, you are so fucking awesome, I stayed up all night last night, and I haven't even turned my brain around yet." Come on, you are in admiration!"

Everyone else laughed, and Li Manli said with a smile, "You can't catch up. I told you not to go to nightclubs. You can't compete with others in appearance and IQ. What should you do!"
