National Forensic Doctor

Jiang Yuan got Sun Jianyu's information, looked at it carefully, and had his hand and foot marks rubbed, and then compared them with the strangulation marks on the deceased.

Sun Jianyu is less than 1.7 meters tall and weighs just over 80 pounds. He is a thin dog with a thin waist, thin legs, and thin arms. The victim Sun Xiuwen weighed about the same as Sun Jianyu. Although she was a woman and had a slight difference in strength, it was more difficult for Sun Jianyu to suffocate her to death.

It's no wonder that there were strangulation marks on Sun Xiuwen's neck. It must have been Sun Jianyu or Liu Mingxue who performed the auxiliary operation. However, the victim's hyoid bone was not broken, which also indicates that the force of the chokehold was insufficient.

Of course, purely from the perspective of insufficient strength, Sun Jianyu's girlfriend, Sun Xiuwen's best friend Liu Mingxue, is even less powerful. However, based on common sense analysis, it is still low for Liu Mingxue, a woman, to take the initiative to deal with Sun Xiuwen by violent means of suffocation when she lacks strength.

"From the current point of view, the two people should have conspired, with Sun Jianyu as the leader and Liu Mingxue as the assistant, to kill Sun Xiuwen together." Jiang Yuan stood at the crime scene, scrolled through his PAD for a while, and gave an answer that was not unexpected.

Forensic doctors have a very important job, which is to identify the real murderer in a murder case involving multiple people. A typical example is when a group of young people fight each other and someone dies. At this time, the person who is mainly responsible is not the person who beat the most people, but the person who performed the fatal operation.

Suppose a wine bottle hit the back of the deceased's head, his heart stopped, and his thigh was pierced... Then the medical examiner must determine what the cause of death was. If it was the wine bottle, he would grab and smash the wine bottle. It was his thigh. As for the one who stabbed someone, or...if he suffered a cardiac arrest, we would all have to go to jail together.

Jiang Yuan determined that Sun Jianyu and Liu Mingxue committed the murder together. After being sent for examination, there is a high probability that there will be no distinction between master and slave.

Meng Chengbiao listened on the other end of the phone and immediately responded: "I agree, Sun Jianyu must have been involved. Liu Mingxue can't escape either. Both of them are minors and their minds are immature. As for the results of the interrogation, I don't think so." question."

"Okay, I'll leave it to you." Jiang Yuan identified the murderer, then walked carefully around the secret base of several people, and then returned to Changyang City with Sun Jianyu's motorcycle.

Although the rut marks at the second site cannot be used to identify the identity, they can be used to exclude them. In this case, transportation must definitely be taken into consideration. Even if the specific motorcycle used cannot be determined, it must at least be proven that Sun Jianyu has channels to obtain the same type of motorcycle.

By the time they returned to the Changyang Municipal Bureau, Wang Chuanxing and others had almost prepared all the materials for handling the case.

The case itself was indeed difficult, but the difficulty was mainly focused on the environment. The heavy rain that night did wash away many things, including the footprints of Sun Jianyu climbing the wall, which could not be proven in the end. Because the fresh footprints were washed away by the rain, the older ones remained.

On the other hand, the behavior of minors who are murderers is also very unpredictable. Including the motive for killing and the way to cover up the killing, they are all non-adult.

As an adult, not to mention whether he would kill someone because of the need to clean and tidy up the room. He would not even dare to throw away the pillow for fear of being discovered by his relatives, so he could only rub and wash it desperately. When the corpse was abandoned, it was not abandoned on the roadside in a hurry, leaving such deep motorcycle ruts.

But to say that the two were brainless, they not only knew how to abandon the body, but also took off the victim's clothes and pants to pretend to be sexually assaulted.

However, Jiang Yuan paid very little attention to these details.

For Sun Jianyu and Liu Mingxue, their ability to resist interrogation is very weak. The current evidence is enough for them to recount the details dozens of times.

Yu Wenshu and others were very satisfied. After receiving Jiang Yuan, they kept saying: "I didn't expect that this case was committed by two minors. Our case in Changyang City is still not perverted enough..."

"It's pretty perverted." Shen Yaowei accompanied the whole process. Although he didn't play any role, he knew the case very well and said: "Two minors had a fight over a trivial matter, and then their best friend and her boyfriend got into it together. The man was killed and his body was abandoned afterwards. If this case is not solved, I don’t know how many victims will be unlucky in another 10 years.”

Yu Wenshu nodded: "Not completely abnormal."

"Thanks to Team Jiang, our task force has never pushed the case forward." Cao Chujun sighed with emotion. He is an old captain who is about to retire. He already cares less about things like face. When he is about to leave, he is more interested in solving a few big cases and appeasing the policeman who has been a policeman for 40 years. Own.

Jiang Yuan smiled and declined. Although he himself assessed that the difficulty of this case was not high, it was difficult for him to say this in front of the former head of the task force, Cao Chujun.

Cao Chujun saw it. Veteran detectives have a vision that may not solve crimes, but can penetrate people's minds.

Cao Chujun's heart was filled with excitement. He grabbed the opportunity before Yu Wenshu could speak and said, "Captain Jiang, there are actually a lot of abnormal cases, especially the backlog of cases in the past. Some cases have been around for too long and are difficult to detect..."

This is straight hook fishing.

Cao Chujun looked at Jiang Yuan enthusiastically.

Jiang Yuan smiled, looked at Yu Wenshu, and then said: "Actually, I'm not pursuing any perverted cases. I can solve some normal murder cases and the sense of accomplishment is also very prominent."

Yu Wenshu said at this time: "You carry more than 30 people with you. For ordinary cases, the cost-effectiveness is too low."

Jiang Yuan was stunned for a moment, but he didn't consider this.

Cao Chujun chuckled twice, read Yu Wen's book, and his tone became more formal, saying: "When it comes to these perverted cases, I think the previous 303 project is qualified."

"Project 303..." Yu Wenshu quickly recalled: "The deceased were the 31-year-old female Zhao Qian, the 28-year-old male Qin Jijian, and the 35-year-old male Gu Daxu... the three of them were doing three-person sports at Zhao Qian's house. Was he hacked to death at home?"

"Yes, it's this case. You still remember the name of the deceased. It's really amazing..." Cao Chujun slapped the most vulgar flattery of the Changyang City Criminal Police Detachment, causing Yu Wenshu to burst into laughter.

"Project 303 is indeed a rather perverted case. The murderer is very skilled and cruel. He has not been able to be solved for seven or eight years. It's time to take a fresh look at it." Yu Wenshu said, looking at Jiang Yuan and said : "I guarantee that the scale of this case is much larger than the previous case."

"In fact, there is no need to pursue the abnormality or scale of the case." Jiang Yuan sighed.

"This case is quite serious." Cao Chujun changed the topic and said: "The murderer of this case entered through the security window on the balcony, and he opened the security window with his hands. After entering, the murderer killed three people in a row. He cleaned himself up and left. His movements were very neat and his skills were very good. No bloody footprints or the murderer’s DNA could be found at the scene.”

"Are all three of them single?"

"They are all married." Yu Wenshu knew what Jiang Yuan wanted to ask, and then said: "The partners of the three people have been investigated and there is alibi. In addition, the three deceased people had more than two sexual partners. It is possible that It’s still relatively secretive, and the case has never been able to identify a suspect.”
