Chapter 68 Three Graves 31 Data

"How do you catch this, do you check the net?" Jiang Chao sighed, "Honestly, I think I feel that the visit to the investigation is not enough."

"Yeah, so I need to find some people to talk about."

"what?"

"If we are sure there will be the next live broadcast, that is, in this school or in the entire city, there are still those who may commit crimes. We can find out these people through some methods and talk."

"The question is, do you have any way to find someone in your psychology?"

"To be precise, use mathematics."

Lin Chen took out three pieces of paper from his pocket. That was something he had been carrying today. Now it seems that he is very fortunate to throw these paper away because of no trouble.

"By using the dynasty." He said to Xun Conglian.

"Why are you so polite? As long as you don't kill, you can use it." Cong Cong Lian replied.

The teenager sitting on the side raised his head from the screen, and his mouth was still signed with a signed pen. Obviously, he was still studying how to say that you could catch those perverted mad: "Boss, I can easily rebel, do you know?"

Lin Chen tied three pieces of paper on the table, saying: "In fact, through the results of MMPI, we found that Wang Shishi, Xu Haozhen, and Jiang Liu have similar personality characteristics. ","

"Find out those who may participate in the next death broadcast?" The dynasty went back to the table in the next second. "There are 30,000 teachers and students from Guangyongchuan University. Want to find the three people who participated in the next live broadcast? Don't say, this is really a needle in the sea. "

"You mean, first screen out the crowd with an introverted personality than or equal to 70 points?"

Lin Chen nodded, and after he was only able to remember the keywords and scoring standards about Xing Conglian, he didn't feel any surprise.

He glanced at the dynasty, and the teenager consciously spit out the signature pen in his mouth, and did not forget to wipe the biting place with a T -shirt.

After receiving the pen, he drew a large ring on the paper, explaining: "Assuming this is a high -scoring person in the society ..." After that, he drew a small circle that intersects with the big circle, " This is a possible criminal person. "He said, and we blacken the two rounds." This is the potential group we may find out. "

"I'm get! This is to let me hit a library first, make the data of this test, and then sieve out the students with a score of more than 70, how many people are there?"

"What kind of library." Xing Conglian knocked on the dynasty, "We can adjust the information through justified procedures."

"70 points are about two standard deviations on the average. Therefore, there will be 4%of the abnormal people." Lin Chen then answered.

"Then there will be 1,200 people even if only the Yongchuan University is sieved!" The dynasty exclaimed.

"Is there any way to narrow the range?" Conglian asked.

"Yes." Lin Chen answered very simply, "Perform another personality test again."

Several suicides in this case all show the characteristics of a major transformation of personal personality, so students with major changes in the scores in the second personality test are high.

"I understand." Xing Conglian said.

"However, there is still a problem." Lin Chen looked at the punishment. "Assuming that we have a personality test on the students, will we not beat the snake?"

"This problem is not big. Now there is such a serious suicide incident in the school. Isn't it a normal behavior to check the mental health problems of students?" Hearing Lin Chen's concerns, punishment continued to say, "And, waiting for you to wait for you Really confirmed suspicious students, isn't it justice enough to interview them as an excuse? "

The words of Xing Conglian made Lin Chen a little speechless: "You really ..."

"What?"

Lin Chen shook his head and expressed helplessness.

"The old traitor is cunning, cunning, cunning, especially shameless!" The young comrade Chao Dynasty answered with great justice.

Xing Conglian didn't seem to care about these evaluations. He frowned slightly and asked Chao Dynasty, "How long will it take you to complete the preliminary screening?"

"This is coming soon."

"How long does it take to implement the second policy?" He asked Lin Chen again.

"The test time only takes about an hour, but the process from organizing staff, arranging test locations to informing students to take the test will be relatively long, and the student base is huge..."

Xing Conglian heard the words and glanced at the time: "It's 16:37 now."

"Yeah, it's almost time to get off work. Even if you notify the counselor now and arrange the test, the first batch of student tests can start around 19:00."

"Do you have an estimate, in which department and in which grade the students we are looking for are most likely to appear?"

"In fact, there will be no significant difference in the scores of students in various departments, but the proportion of students in the Department of Psychology is relatively high..."

Xing Conglian couldn't help laughing: "Does this count as self-pitying?"

Lin Chen picked the corner of his mouth and continued: "According to our school's information, there are also students from the medical school and the chemistry school..."

"How many students are involved?"

"Report to the boss, there are 3158 people in total." Comrade Wang Chao replied quickly.

"Meaning, the test can't be done today anyway, right?"

"Even if 20 classrooms are opened at the same time and 800 students take the test, it will take five hours to complete."

"It will be tomorrow morning at the earliest."

But even tomorrow morning, 20 hours have passed.

Xing Conglian nodded and continued to ask, "Can you narrow down the scope a little more?"

"From the perspective of grades, freshmen have just taken the entrance test, so they don't need to take the test again. Many senior students have started internships and are no longer on campus. They are directly excluded. Therefore, it is good to choose the second and third year students directly."

As soon as the two of them finished speaking, they only heard Wang Chao hit the Enter key neatly.

"A total of 1342 people!"

It is indeed very pleasant to work with efficient partners: "I need to trouble you to pick out sophomores and juniors from the Department of Psychology, School of Medicine, and School of Chemistry, and then pull a list for me." Lin Chen said.

"Small meaning." The young man heard the words and tapped the keyboard a few times. He stared at the generated data, and said to Lin Chen, "Don't say it, Ah Chen, your psychology department is really special."

"Yeah, I've always been weird." Lin Chen shrugged his shoulders very rarely, and said, "Send me the list, resume, and test results of these people."

"already sent."

In short, Lin Chen probably understood why Xing Conglian had to take the dynasty with him, it was too easy to use.

After the boy finished speaking, he took out a tablet from his backpack and handed it to him: "Look at it with this."

"If we have this list in hand, we can cross compare the circle of friends of the six deceased in this case to see if there is any overlap?" Jiang Chao asked suddenly.

"Yes, yes." Chao Chao took out a candy and threw it into his mouth, "Why are you looking for someone to do it, I still have a lot of things to do."

Even if it was a relaxed and relaxed dynasty from beginning to end, the investigation is still under pressure.

Large-scale population screening and tight time are almost naturally contradictory.

He continued to connect to the dark network, and pressed the refresh button a few times irritably, as if he could get a response from someone on the other end of the network.

"If Captain Jiang has a directory, can you help him do a comparison analysis?" Lin Chen held the boy's hand in a gentle tone.

"It will take a long time to compare, and there is no response from there, I will keep an eye on the reply."

It is rare for the young man to reject him.

Probably because his abilities are almost impossible to use in this dark world, so he is more eager to play a role and defeat something.

As if seeing through the young man's mind, Lin Chen shook his head and said, "You should do more important things."

"Have you heard, let Ren Xian watch the bounty later, at least you teach it, and the standard won't be too bad." Xing Conglian is rarely too tough, "However, if within half an hour, we haven't When a response is received, some more extreme measures need to be taken."

"What do you want to do?" Lin Chen asked.

"Our current fishing net is too small..." Xing Conglian looked at Lin Chen, "It's mainly because you inspired me to find a needle in a haystack. Assuming that the murderer behind the scenes is using live broadcasts to make money, then he can't be too repulsive to newcomers to join, secretly. There are also many underground forums on the Internet, we can write some topic posts, um..."

"You want to say, let me imitate the tone of a psychopath, write a theme post, distribute it on major websites, and widen the fishing net?" Lin Chen keenly noticed the trap.

"You are more professional." Xing Conglian was a little embarrassed, so he took the initiative to say, "I can be responsible for the translation."

Although he was speechless, he had to say that Xing Conglian's opinion was still very reliable. Just as he was about to answer, he heard the other person say, "Consultant Lin knows where the toilet in the office building is. Could you please take me there?"

Xing Conglian is probably the type who finds someone to talk to alone, and has to take into account the mood of other people in the room.

Lin Chen went out with him, and sure enough, the captain of the criminal police didn't mean to solve the physical problem at all, he just found a window, opened the window halfway, and lit a cigarette.

"What's up with him?"

Lin Chen was a little surprised. He didn't expect Xing Conglian to call himself out to inquire about the psychological state of the dynasty.

"He must be nervous."

"Are you nervous?"

The question changed too quickly, and Lin Chen couldn't react.

"not yet."

Light-colored smoke rose up, and Lin Chen was a little uncomfortable being stared at by him.

"Anyway, I hope you don't feel too much pressure. If you have any problems, you can tell me." Finally, Xing Conglian spoke.

At that moment, Lin Chen suddenly understood Xing Conglian's intention, he almost shook his head helplessly, Xing Conglian really passed his head.

From the beginning to the end, Xing Conglian did not ignore the most critical issue. He knew that Zheng Dongdong had a grudge against him, and he knew the housekeeper Chen, and he could properly use these two people to set up such a big trap. Such a behind-the-scenes manipulator seemed to be against him. Everything is too familiar.

"If you want to know, you can buy me a drink when this case is over."

Lin Chen raised his head, looked into Xing Conglian's eyes, and said this.
