After Cha Junxian left, the family was very puzzled, what did Cha Junxian do in the past because of the murder, of course, the family was not too worried, after all, the police couldn't find Cha Junxian because it was related to the murder.

Driving to the Seoul Police Station and entering the office where the strong squad is located, Cha Junhyun saw a familiar figure in the distance at first glance.

Although they have not met on official occasions, Cha Junxian has seen him in books, and it is Ping Changyuan, whom Cha Junxian respects very much.

Even Omoto Changyuan is here, it seems that things are not simple.

When the deputy chief investigator of the police station found out that Cha Jun-hyun was coming, he immediately greeted him and explained as he walked, "In fact, we have encountered a trouble, so we hope that Professor Pyo Chang-won and Lawyer Cha can assist us in our investigation." ”

"What's the trouble?"

"A serial homicide."

After a simple conversation, Cha Junxian realized the seriousness of the matter, in front of the conference room on the side of the corner, Pyo Changyuan stood in front of a whiteboard, and there was a circle of policemen sitting in front of him. ”

Holding Pyo Changwon's hand with both hands, Cha Junxian said, "It's my honor to meet you. ”

After saying hello, the director of the Seoul Police Station stood up and said, "This case is very urgent, so we invited Professor Pyo Chang-won and Lawyer Cha to come and assist us in the investigation. ”

I sat on the chair in the back with Pyo Chang-won and watched as the squad leader of the strong squad began to paste photos on the whiteboard and write with a marker, and soon, the structure of the case came out, and 4 photos were posted, all of which were female victims.

The beginning of the case started from Sokcho, the first victim, Luo, was 22 years old, a reception staff at a reception desk of an extracurricular college in Sokcho, disappeared after work on the evening of April 17 this year, and the body was found in a forest in Sokcho, and was sexually assaulted before his death, but no fingerprints were left at the scene, and no liquid was found in the victim's body.

His hands were tied with a red rope at the time of death, his clothes were intact, and the cause of death was the obturator artery (which runs anteriorly and down the lateral wall of the pelvis, penetrates the obturator canal to the inner thigh, and branches to the medial thigh muscles and hip joints. The ruptured blood was too much, the only wound was on the left inner thigh, and the blood from the broken artery did not spread, but flowed into the mud puddle below the inner thigh.

The body was found by an aunt in the morning, the scene was not destroyed after the police, the National Science Institute immediately sent people to conduct a blockade search, the murder weapon has not been found so far, judging by the shape of the wound, the preliminary estimate is a sharp small blade, most likely a scalpel, the incision is very neat, and there is no fracture, and there are no other abnormalities in the autopsy report made by the forensic doctor of the National Science and Technology Search.

The second victim, Kong, 21, who worked in a library in Shuangmentong in the north of the city, disappeared after getting off work at 5 p.m. on April 24 this year, and the body was found in the backhill forest of Bukhansan Fortress the next morning, and the body was found by a staff member of Bukhansan National Park.

When he died, he was also tied with a red rope with his hands, his clothes were intact, he had been sexually assaulted before his death, and no evidence was left at the scene.

The third victim, Song, is 20 years old, working in a K fashion store in Qingliangli, disappeared after getting off work at 9 p.m. on May 1 this year, and was found dead by a farmer at 3 a.m. on the edge of the ridge in Luhua Village.

The fourth victim, Shen, a 19-year-old employee of the M fast food restaurant in Shangdaodong, disappeared after getting off work in the early morning of May 8 this year, and was found dead in the woods behind Shangdaodong the next morning, and the others were exactly the same as the previous three victims.

After listening to the basic information, Cha Junxian did not speak, Biao Changyuan looked at Cha Junxian slightly sideways, and the other people present also focused their eyes on Cha Junxian.

Not knowing what this meant, Cha Junxian just subconsciously stood up and walked to the front of the whiteboard

After carefully observing the photos, he said: "It should be judged from the basic information that the murderer is a very calm person, and he understands medical knowledge, and he is very clear about the distribution of major arteries in the body, and knows how to make the victim die cleanly. ”

The murderer must have known all four victims, all four victims suddenly disappeared on the way home from work, that is, the murderer mastered their whereabouts and routes, and the other three did not struggle, it may be that the first crime scene was not in the place where the body was found, there are two possibilities in this situation, first, the murderer led the victim to this side, and then suddenly attacked and knocked the victim unconscious, and second, at another crime scene, the victim was stunned before moving to the scene where the body was found.

However, the second possibility is very low, so the murderer must have known the victim, the relationship is still very close, it is inferred that he is a male murderer, he will not be more than 30 years old, and his appearance and height are better than ordinary people, and he has not found the same person in the place where the four victims worked, he has participated in any tutoring in an extracurricular college, he has gone to the library to borrow books, he has also bought clothes in a trendy clothing store, and finally visited M fast food restaurant, of course, the above four must meet the condition of long-term.

The murderer has a habit of cleanliness, and the appearance of the four victims is very good, so he doesn't want to be destroyed when he dies, and he knows that there are traces of tidying up when he looks at the neat clothes, if it is a serial homicide, then the murderer will commit murder tonight, judging from the time of the murder of the four victims, the murderer acts every 7 days.

Speaking of this, Cha Junxian stopped, and his eyes locked on the powerful squad leader beside him, this is just basic information, and there will definitely be information after the investigation and screening of the murderer.

In fact, the reason why Cha Junxian was asked to go up first to analyze and reason was mainly because the director was worried that some police officers would disobey Che Junxian, so he asked Cha Junxian to show his strength to convince the public, there were 7 policemen present, Cha Junxian just deduced that there was no mistake based on basic information, and it was obvious that the effect had been achieved.

Returning to his seat, he followed the strong squad leader and began to explain the information found after the investigation and evidence collection, and at the same time listed two target suspects, not one but two, which surprised Cha Junxian a little, which is why the police station asked Cha Junxian and Pyo Changyuan to come over to assist.

After describing all the relevant clues of the case, the director said that he had sent someone to follow the two suspects, and then walked up to Che Junxian and said: "Now I officially ask Lawyer Che to join our investigation team this time as a crime consultant." ”

Please, Chang Yuan, Cha Junxian, still think about it, please ask yourself.

"Director Nim, I'm just a lawyer, and I'm ...... solving cases"

Before he finished speaking, Biao Changyuan on the side spoke: "Lawyer Che doesn't need to be modest, I have watched the crime scene show you starred in, your analysis and inference are very sharp, and there is a reason, if it is in reality, you have also reached the level of members of the Criminal Investigation Association." ”

This is the highest compliment, Cha Junxian hurriedly waved his hand and said: "No, the professor is too prestigious, I have just read a lot of reasoning books, and I have also read all the professor's books." ”

The director took over the topic and said: "No matter what, this case is for the two of you, if there are new victims, it will definitely cause panic in the society." ”

Biao Changyuan nodded and said that he would do his best, and after speaking, he looked at Cha Junxian and said, "It's just that I suddenly invited Lawyer Che, after all, Cha Junxian needs personal time now, right." ”

Knowing what he was talking about, he waved his hand, and Che Junxian said: "Private matters are not important, since I have joined the detection team, I will work hard." After speaking, Che Junxian asked the director: "By the way, can I go to the national science search?" I want to talk to the forensic doctor in charge and look at the corpse in an instant.
