crime scene

"Let's check the information on the victims of cases No. 1, No. 5, and No. 7." Su Nian continued, the movements of his hands did not stop, as if opening a valve, the more he memorized, the faster he memorized.

Xie Qian could see that he had found a breakthrough, so he took the file and looked through it.

Jing Sheng was still there in a daze, "Isn't it in the file?"

"You think you'll be done after you find your personal files and visit a few neighbors, and treat it as a joke? It's not that I said that with your work attitude, you don't take it seriously, right? If you ask you to check, you can check wherever you are. Then What nonsense!"

Xie Qian's painful education stopped, and Su Nian also stopped writing. He showed the similarities he sorted out to Xie Qian, while he rested his chin in a daze.

In Jing Sheng's eyes, he was in a daze, but he was actually thinking about the case.

"Male, height 165 to 175, age 25 to 35 years old, thin body." Su Nian said in a low voice, "I still don't know why he killed people, and I can't guess his psychological appeal, but according to this momentum, he has It may continue to commit crimes, but Jing Sheng is right, it cannot be an organ transplant."

Xie Qian looked at Su Nian's notes. It was a drawn form, from No. [-] to No. [-]. The time of committing the crime, the basic information of the deceased, and the harvested organs were listed on the header.

The connection between them is in the last column, except for No. [-] and No. [-], which are empty, and the others have been sorted out.

Victim No. 2 was a child, female. The removed spleen is the largest immune organ in the body, and the spleen of children in this age group is the most vigorous.

Victim No. 3 was deaf-mute, male, and his eyes became his most sensitive and useful visual organs.

Victim No. 6 was a retired gymnast, female. Athletes generally avoid alcohol and have a good liver.

Most of the victims were women or socially disadvantaged groups, indicating that the murderer was thin and weak, and he was not sure about subduing men who were taller than him.

Jing Sheng sat across from him and kept scratching his head, "Captain, what information do we need to find out... Look, I'm just a forensic doctor who doesn't understand this, why don't I call Sun Siyuan or Zheng Ronghua over?"

Oh, by the way, Jing Sheng is not Chu Duanyu after all. Think about how Chu Duanyu was in exactly the same state as Jing Sheng when she first followed Xie Qian to investigate the case.

"Check their occupations, or living habits, hobbies and personalities." Su Nian replied.

"Ah okay... I'll check first."

Jing Sheng felt a little wronged.

His little daughter-in-law is still waiting at home. She is obviously a forensic doctor, why should she work in the criminal investigation department, and there is no bonus.

"Give me the phone number, the two of you can check it quickly." Xie Qian said.

It was nearly 12 o'clock noon, and the snacks that Xi Qian bought were almost eaten. Su Nian re-watched the video of the site survey several times, but still didn't find anything of value.

"Nian Nian, Victim No. [-] learned ventriloquism when he was young, and often performed on the overpass. When he was old, he liked to bicker with his neighbors when he was free." Xie Qian said.

Su Nian picked up the pen and completed the form.

"Victim No. 7 is a polar sports enthusiast, rock climbing, skydiving, bungee jumping, etc..." Jing Sheng reported, licking his dry lips, "No. people."

Su Nian didn't stop writing, and continued to ask while eating the biscuits, "Hobbies are clubbing and drinking, nothing else?"

"Well... Yes, there are red marks and welts on his body. His friends said he has an interest in that."

"which aspect?"

As soon as he heard his words, Xie Qian coughed dryly immediately, Su Nian was taken aback for a moment, and then understood what he meant, pursing his lips with a flickering expression.

"He...does this often, and his private life is chaotic." Jing Sheng said with a grin.

"To what extent is the confusion?" Seeing Su Nian's shy appearance, Xie Qian had no choice but to ask.

"Both men and women take it all, and most men are looking for men. He is good-looking. He is the one below, and the number of times is frequent. Three or four times a week. If you don't find him uncomfortable." Jing Sheng replied, and he didn't forget to add a sentence, " Not as good-looking as my wife."

His wife... a man.

Xie Qian's brain froze for three seconds, subconsciously glanced at Su Nian.

There was no abnormal expression on this kid's face.

"Well, the little prince of the nightclub, sex addiction behavior disorder, good kidney."

"These are the map markers of the seven crime locations. He should be a local, and he is very familiar with terrain, traffic, and personnel exchanges."

Xie Qian didn't just stay up all night with Su Nian, he also took a pencil to draw a summary on the map, but compared to Su Nian who can use his brain, he can really do not have many things to do.

Su Nian handed the form to Jing Sheng.

Jing Sheng took it and looked at it for a long time before raising his head and asking, "What do you mean?"

"This is what the seven cases have in common, and they can go through the merger procedure." Xie Qian explained, "Go and make a phone call."

"Oh... oh oh oh oh oh oh!" Jing Sheng suddenly realized, and stood up excitedly, an expert is an expert, and he finished the work that had not been handled for two months in one night.

Su Nian and Xi Qian frowned in unison at this time, the case was merged, but the suspect's motive for committing the crime could not be found, his appeal could not be seen, and it was impossible to judge whether he would continue to commit the crime, or the next one. Who is the target of the crime.

In other words, the next case may happen at any time, or it may not happen in this life.

And there is no connection in time. The suspect seems to commit the crime according to his mood, but he can investigate the victim's situation and attack in a targeted and planned manner, which does not seem to be arbitrary.

This is the toughest question at this stage.

"I'm going to buy lunch, don't run around." Xie Qian thought that he couldn't figure it out anyway, so he might as well eat his fill first, so he patted Su Nian on the shoulder and got up to go out.

Only Jing Sheng and Su Nian were left in the room.

Jing Sheng was a little embarrassed, didn't know what to say, opened and closed his mouth several times.

"That... Zheng Ronghua said he would be there soon."

Su Nian nodded, and pointed to the bed where Jing Sheng slept, meaning let him tidy it up.

Jing Sheng looked in the direction of his finger, and asked in a daze, "What do you want to take?"

"No…"

Su Nian is still too uncomfortable to adapt to the new environment and new people. He is not very good at communicating with people, and he doesn't like to put himself in an unfamiliar environment.

It is enough to leave these things to Qianqian.

Su Nian took a sip of coffee and waited obediently in the room for him to come back.

"Why does he want organs? It's not for transplantation, but for specimens?" Jing Sheng muttered softly, "Ah, Police Officer Su, I'll go out and make a phone call."

Su Nian nodded.

Going out to make a phone call must be for personal matters. Based on Jing Sheng's words just now, it is not difficult to guess who he is going to call.

Not only did he generously admit his sexual orientation, but he could also bravely disclose this relationship. Su Nian pursed her lips and looked at her differently.

Xie Qian led the beef noodles and entered the room with Zheng Ronghua. At this time, Su Nian had already prepared the required materials and was waiting for Zheng Ronghua to take them through the formalities.

"But Officer Su, I still want to ask, why is the murderer alone?" Zheng Ronghua asked.

Su Nian took the chopsticks from Xiqian, picked up the noodles and blew them in front of her, while thinking about how to explain to Zheng Ronghua.

"The murderer killed the No. [-] victim and left footprints at the scene, and found the suspected murderer's hair at the No. [-] scene." Xie Qian opened his mouth and answered Su Nian, "That's the reason."

"Huh?" Zheng Ronghua was taken aback for a moment, his brain froze because he couldn't keep up with the two people's thoughts.

"This is the most basic thing in criminal investigation, Locard's law of material exchange!" Xie Qian didn't know whether to laugh or cry.
