Looking at Guan Shan's blazing eyes, Luo Chuan suddenly said, "Yes...... Proof of their identity! The necklace of the first deceased, according to witnesses, is the name of the deceased in the shape of a cloud. This second deceased also seems to have a name on the ring. In this way, the murderer is not only unwilling to deprive the deceased of his identity, but also deliberately leaves their status symbol! ”

Listening to Luo Chuan, the more excited he became, Guan Shan also smiled and continued: "That's right, generally killing people and discarding corpses will deliberately cover up or distort the identity of the deceased, and use this way to avoid investigation." And the murderer of this case did the opposite. His modus operandi was not only on the wool, but also on the deceased's clothes and poses, so it was impossible for him to have negligently forgotten to take away the status symbol, but deliberately left it. ”

Luo Chuan nodded, looked at the big tree again, and said to himself, "Yes...... Perhaps, because the murderer already knew them. Leaving their identities is to give themselves a sense of accomplishment and to remember who this person is forever. ”

"But we still don't know what the point of that is." Guan Shan tries to come up with all kinds of possibilities, but how complex is the human mind? Analyzing a psychopathic suspect in twenty hours, how can it be so simple.

Luo Chuan took the lead and walked back, lowered his head and asked Guan Shan: "What are the symbols that can represent a person's identity?" ”

Guan Shan said as he walked, "Hmm...... For example, name, birthday, DNA, personal signature characteristics......"

"Name...... Birthday...... DNA ......" Luo Chuan muttered to himself, as if he was trapped by himself. He felt like he could grasp something, but it was fleeting, and he couldn't say why. Again, time is running out now, and it is difficult for him to concentrate completely when he is in a hurry.

Guan Shan walked out of the cordon, pointed around to Luo Chuan and said, "I think the geographical scope of criminals' crimes can be reduced again. Previously, we speculated that it would take an hour to get from the location of the crime to the mall, but now combined with the geographical location here, and with the mall as the center, it will only take about half an hour. The terrain and roads near the shopping street are complicated, and aside from the unexpected factor, I think this person is very close to the shopping mall. ”

"Well, that makes sense. These girls are very young. The vicinity of the business district should be the place where they will be more likely to appear. Murderer...... That's where you met them? Can ......"

"But you've always thought this case wasn't random, right?" Guan Shan quickly took Luo Chuan's words.

"Yes. He has his own specific goals. We still have to look for clues from these victims. Luo Chuan said, his steps also accelerated, and he hurried back to the police force to see what was going on.

Based on the experience of the previous time, the autopsy was significantly faster this time. And Xing Lao can also start the order correctly, instead of spending hours cleaning up the wool when he comes up.

When Luo Chuan and Guan Shan returned to the police force, they waited anxiously for a few hours, and after doing countless geographical profiles, they finally waited for Xing Lao's "call".

Luo Chuan couldn't wait to take Guan Shan to the forensic office, and when he entered the door, he saw Xing Lao sitting on a chair and sneezing non-stop.

Luo Chuan hurriedly took two steps and asked with concern: "Are you old ...... Is this a wool allergy? ”

"Ahh Xing Lao's tears came out, wiped his nose, waved his hand and said, "No, I suspect that the animal is allergic to wool, this time, he is far less meticulous than last time." In comparison, it's simply shoddy. In order to present the same effect, he mixed a lot of cotton wool. I was careless, and when I dismantled it, I brought out a lot, and I was afraid of polluting the evidence, so I quickly ran out and sneezed. ”

"Why not the first time?" Luo Chuan was a little surprised, and frowned puzzled.

Xing Lao said as a matter of course: "This kind of project can consume a lot of energy if it can be done once, even if he is crazy, he always knows that he is tired and annoying, right?" ”

Guan Shan shook his head very seriously at this time and said, "No, people who are not in a good mental state have different feelings about everything than ordinary people. That's why, some psychosis can have no pain, no exhaustion, no shame, and so on. Their spiritual world occupies the true sensations of the body. Like this suspect, in the case of the first victim, he can repeat the action of poking the needle for so long and so many times, which is enough to show his obsessive-compulsive behavior. It was so serious, he must have been tireless, and he was getting more and more excited. ”

Listening to Guan Shan's veto of his idea, Xing Lao took another tissue and wiped his nose and said, "Maybe it's just enjoyable, tired of it." Eh, don't you think that's a good sign? He doesn't have that bian'tai meticulousness, maybe he will stop! ”

No one responded, Xing Lao looked at the two people in front of him in confusion, glanced at Luo Chuan, and glanced at Guan Shan, only to find that their expressions were becoming more and more solemn.

Just when Xing Lao couldn't help but want to speak again, Luo Chuan took a deep breath a little heavily, and then patiently explained: "Xing Lao, this is not a good phenomenon. If, as you say, he is becoming less and less meticulous and more shoddy, that only proves ...... The frequency of his crimes accelerated. He doesn't have that much patience with the same victim anymore, he needs more victims...... That is to say......"

Guan Shan glanced at Luo Chuan and took what he didn't finish: "That is, we don't even have twenty hours left." Soon, a third doll will be discovered, and this time, his craftsmanship may be even more unelaborate. ”

Xing Lao was stupid when he heard this, and quickly stood up and stuffed the two reports to Luo Chuan, and said anxiously: "Then you guys go quickly!" It won't help you much for a while, and the situation is the same as last time, and the low temperature environment hasn't changed, so it should be the same place. If you find that place, you might be able to save a girl...... Yes? ”

Luo Chuan nodded, and as soon as he turned around, Xing Lao shouted to him again: "Luo Chuan! Watch his hands! ”

"Huh?" Luo Chuan turned around a little unresponsively.

Xing Lao stretched out his right hand and made a needle-twisting motion, reminding Luo Chuan: "He pinched the needle for a long time, and the faster he went, the more unbearable his skin was." The speed of his crime, there must be scars on his thumb and forefinger! ”

Luo Chuan's eyes lit up: "Thank you." ”

Out of the forensic office, Guan Shan whispered to Luo Chuan: "You get ready, the third victim, I'm afraid it will ......."

"I know. But the faster he acts, the more flaws he will have. Xing Lao has already given quite useful clues, and now, since I can't save the third person, I don't want to waste time on him. Luo Chuan's steps were fast, but he was not blindly hurrying, he seemed to have grasped the key point.

Guan Shan didn't rush to ask, and all the way back to the office, Luo Chuan began to arrange for someone to investigate the identity information of each victim. and called Ke Xue and asked him to find out what the identities of the two victims had in common as soon as possible.

Everyone was a little curious, thinking that in such a time-critical situation, Luo Chuan would definitely take the location of the crime as the main target of the investigation, and they didn't understand why he changed direction.

Luo Chuan didn't sell it either, he knocked on the report on the table and said: "There must be some kind of connection between the victims!" They knew the murderer, and even if they weren't familiar with it, they must have met. Otherwise, the murderer would not have been able to speed up the crime. ”

"Why ......?" One of the police officers couldn't help but ask, he didn't understand what the necessary connection was.

Luo Chuan threw the relevant information of this case on the table with great momentum and said: "He accelerated the speed of the crime, it is not possible to avoid risks, but to get rid of the next victim as soon as possible." We have reasoned before, and the next victim is likely to be in his hands. So, what kind of means does he need to achieve such a morbid demand? I'm sure it wasn't random, it was premeditated. However, in our profile, the murderer is not a very charismatic person. Then if he wants to control and capture these girls, there must be a way and a way. It could have something to do with his job, his address, or some other condition. Immediately, we investigate based on victim identity information. Their name, family, school, employer, birthday, household registration, etc. Any similarity may reveal the murderer's information! ”

Seeing Luo Chuan like this, everyone immediately got busy. Guan Shan sat leisurely on the sofa and drank a glass of water, quietly not knowing what he was thinking.

"What do you think?" Luo Chuan asked.

"Think about your next step."

"What's next?"

Guan Shan smiled: "Yes, you have already analyzed this step, so the next step is how to determine the way the murderer locks the target." ”

As he was talking, Ke Xue ran over excitedly, patted the table and said, "Team Luo!" Team Luo! You're so godly! I, I've found common ground!! ”

"Say."

Ke Xue's excited expression disappeared in an instant, and she said with some unpleasant taste: "When were the two victims found...... It's their birthday. ”

"Birthday??" Luo Chuan repeated, and those fairytale-like on-site decorations, toys, books, and jewelry quickly appeared in his mind.

Guan Shan raised his eyes and looked at Luo Chuan: "Look, it's the next step, right?" You've identified the similarities between the deceased, and what about after that? ”

"We know that the murderer most likely chose the deceased based on his birthday." Luo Chuan looked at Guan Shan with some confusion.

Guan Shan spread his hands: "And then?" Who can grasp the birthday identity information of a large number of women? ”

Luo Chuan was silent.

But Ke Xue cautiously interjected on the side: "The household registration police ......"

The police officers who were listening to the audience all made a coax, and some people threw a paper ball at Ke Xue: "Xiaoxue! How did you finally get into the police? Even if it is a household registration police, it has been strictly assessed! Do you think we can have such people in the police? ”

There was also a police officer next to him who expressed his thoughts: "Moreover, it doesn't have to be a household registration police to have such an opportunity!" Driver's license, ID card, handling lost ID card, insurance...... All of these staff members have access to personally identifiable information! ”

"Yes, yes, yes! To buy a phone card, you have to have identity information! In this way, there is also the possibility of committing crimes in business halls and mobile phone sellers! ”

Everyone has their own thoughts and guesses. But in this way, Luo Chuan had a headache. Everyone has a point, there are so many ways to know personally identifiable information these days...... This clue is simply overwhelming. It can be seen that Guan Shan began to think about the next step in advance...... That's exactly right.
