Profiler 2: Criminal Investigation Brigade

Then it got down to business, a thick stack of files was placed in front of Lu Yuanli in the blink of an eye.

The No.1 missing girl, 14-year-old Yang Mouli, a junior high school student, disappeared after going to KTV with her classmates for her birthday.

The last victim was 15-year-old Li Moulin, a third-year junior high school student.The school organized an outing that day.In the afternoon, the student went to the teacher and said that he was unwell and had a stomachache, so he had to go home first.

When the school goes out for activities, students often have symptoms of discomfort.Li Moulin's class teacher didn't think much about it, so he asked if he wanted to send her back.Li Moulin said that she can call a car by herself.The teacher also specifically told her to take a regular taxi and not a part-time car.Later, seeing that a taxi was coming to pick her up, the teacher in charge told her to go with her.At 5:00 p.m., the students returned to school by bus.

When it was almost 7:00, the parents called to ask the teacher, saying that the student did not go home, and then disappeared.

All in all, the seven victims, not two students from the same school, were from good or bad family backgrounds, with strong or poor grades.Five girls and two boys, probably the only thing they have in common is that they are not bad in appearance.

Moreover, the police officers visited a large number of teachers and classmates. Before the disappearance, the victim had almost no abnormalities, and there was no obvious decline in academic performance.

Because the victims were all in puberty and the rainy season, the police officers also considered the problems caused by puppy love.However, almost all of these victims had more than one "gossip target" in the school. After investigating one by one, no obvious abnormalities were found.These students have also been attending classes at school normally, and no one has disappeared without reason.For students of the same age group, if there is a problem, it is almost an impossible task to not reveal any flaws under the interrogation of the police officers.

The reason why these disappearance cases are all dealt with together is because except for the last case, which disappeared during an outing in the suburbs, the other victims all disappeared in leisure and entertainment places such as KTV, bars, and fashionable restaurants.And, so far, no trace of the victim has been found.The age of the victims was similar, and with the level of public security in Shanghai, there had been no cases of missing teenagers and children in succession for many years, so they were dealt with together.

"So, this case has a very strange point."

Lu Yuanli said: "That is, there is no abnormality. Before I came, I also read some background information. We have a very complete and strict public area monitoring system here, what is it called..."

Jiao Yang subconsciously said, "Sky Eye Project..."

"Correct."

Lu Yuanli glanced at him with a smile, and said approvingly as before: "But these few students seem to have disappeared from the world, and there is no video material to capture the situation before their disappearance. In addition, there is an information explosion now. Weibo, WeChat, QQ, INS, everyone has countless social tools and software, leaving traces of life and actions, but now, after checking all of them, there is no clue, this is a special point. "

Zhang Xianning said: "Professor Lu's reminder is correct. I think this abnormality may be the breakthrough point of the case."

"But because I just arrived here, I don't know much about our national conditions. I still can't figure out what caused this."

Lu Yuanli thought for a while, and said: "So, in fact, the evidence is not sufficient for the current case to be merged. According to the available information, in my personal opinion, the possibility of an acquaintance committing the crime is very low, so basically there is no need to consider it. Because, if it is because of For reasons such as emotional disputes caused by puppy love, the victim will be linear and can connect a network of relationships, but now, this is not the case.

Therefore, there seems to be a slight problem with the current direction of investigation.I think the focus should be on investigating the scene of the disappearance, such as whether the KTV staff or other guests who were present at the time were found, who took the victim away, and whether there are any witnesses. "

Jiao Yang couldn't help but said: "So you feel that it wasn't an acquaintance who committed the crime, but a random stranger who took them away?"

Lu Yuanli said: "In general, it can be said that there are few materials at present, but I can also make a simple profile statue for the criminal. First, the criminal is male. The serial vicious. The creator of the incident, about 99 years old. More than % are men. I don't think this time will be an exception. With the current state of domestic economic development, teenage children have developed well and their body shape is close to that of adults. Female suspects want to subdue them and take them with them easily. It is not easy to walk them away.

Second, this person should not be very old.The ages of several victims are all in adolescence, especially girls, which happens to be the time when they are most wary of strangers, especially strange men.Then, the similar age can easily reduce the vigilance of the victim.Therefore, the age of criminals should be between adults and minors, or between those who have just stepped into society.

Third, criminals have outstanding appearance, are not too aggressive, and have strong language skills.The reason is the same as above, if you can easily take away strange boys and girls, your appearance will naturally attract people's liking in the first place.It may seem that he is not strong, with a slender figure and some melancholic temperament.This kind of trait makes people seem to feel pity and relax their guard.

Fourth, criminals should come from a good family background and be well educated.If already working, he also has a respectable fashion career.Except for the library, other places require a certain amount of spending power.

Fifth, the students who disappeared during the spring outing in the suburbs indicate that the criminal should have a personal vehicle.Focus on checking the taxi driver called by the taxi app to see if he finds anything unusual.

Sixth, criminals have strong anti-investigation capabilities.In addition to the suburbs, other entertainment and leisure places are generally monitored, but for the time being, no one has photographed him/her. The surveillance video of him/her taking the victim away shows that the criminal is consciously avoiding the surveillance and taking the victim away . "

Because the last case occurred recently, theoretically the clues are the most preserved and the best, and the hope of the missing student's survival is also the greatest. After the meeting, according to Lu Yuanli's suggestion, Hou Xiyong and Yu Xiaoguang called the Didi driver Ji Xiaoqiang back.

This was the third time he was brought back to the police station to assist in the investigation. Ji Xiaoqiang was dejected and even called out his luck.

Jiao Yang lowered his face and said: "Ji Xiaoqiang, the surveillance video shows that you were the last to see the missing student Li Moulin. You did have two passengers as time witnesses that day, but when did the child have an accident? No one knows, we have the right to detain you for 48 hours. Now, should we actively provide clues to help the police solve the case as soon as possible, catch the real criminals, and clear their suspicions at the same time, or treat them as criminal suspects and continue to be detained In the office, you can figure it out yourself!"
