Chapter 1060 A bit of scale
Jiang Yuan took Sun Jianyu's information, read it carefully again and again, and asked someone to make rubbings of his hand and foot marks, and then compared them with the strangulation marks on the deceased's body.
Sun Jianyu is less than 80 meters tall and weighs just over kilograms. He is a skinny guy with a thin waist, thin legs and thin arms. The victim, Sun Xiuwen, weighs about the same as Sun Jianyu. Although she is a woman and has a slight difference in strength, it is difficult for Sun Jianyu to suffocate her to death alone.
It is no wonder that there are strangulation marks on Sun Xiuwen's neck, which should be assisted by Sun Jianyu or Liu Mingxue. However, the victim's hyoid bone was not fractured, which also shows that the strangulation force was insufficient.
Of course, if we analyze it purely from the perspective of lack of strength, Sun Jianyu's girlfriend, Liu Mingxue, who is also Sun Xiuwen's best friend, is even less powerful. But from common sense, as a woman, Liu Mingxue, when she is not strong enough, is unlikely to take the initiative to use violence to kill Sun Xiuwen.
"From the current perspective, the two should have conspired together, with Sun Jianyu as the main person and Liu Mingxue as the auxiliary, to jointly kill Sun Xiuwen." Jiang Yuan stood at the crime scene, swiped his PAD for a while, and gave an answer that was not unexpected.
One of the most important tasks of forensic doctors is to identify the real murderer in a murder case involving multiple people. A typical example is a fight between a group of young people, and someone dies as a result. In this case, the person who bears the main responsibility is not the one who beat the most people, but the one who performed the lethal operation.
Suppose the deceased was hit by a wine bottle on the back of his head, his heart stopped, and his thigh was pierced... then the forensic doctor would have to determine what the cause of death was. If it was the wine bottle, then he smashed the bottle; if it was the thigh, then he grabbed and stabbed the person, or... if it was cardiac arrest, then everyone would have to go to jail together.
Jiang Yuan determined that Sun Jianyu and Liu Mingxue were guilty of joint murder, so after the case is sent for examination, it is likely that the verdict will be regardless of whether they are the master or the servant.
Meng Chengbiao was listening on the other end of the phone and immediately responded, "I agree. Sun Jianyu must have been involved. Liu Mingxue can't get away either. Both of them are minors and their minds are not mature. I think there will be no problem with the results of the interrogation."
"Okay, then I'll leave it to you." Jiang Yuan identified the murderer, then carefully took a tour of the secret base of several people, and then took Sun Jianyu's motorcycle back to Changyang City.
Although the wheel tracks at the second scene cannot be used to identify the same person, they can be used to exclude the identity. In this case, the means of transportation must be taken into consideration. Even if the specific motorcycle used cannot be determined, at least it must be proved that Sun Jianyu had the channels to obtain the same type of motorcycle.
When they returned to the Changyang Municipal Bureau, Wang Chuanxing and others had almost prepared the case materials.
This case itself was indeed difficult, but the difficulty was mainly due to the environment. The heavy rain that night did wash away many things, including Sun Jianyu's footprints when he climbed the wall, which ultimately could not be proven. Because the fresh footprints were washed away by the rain, but the older footprints were left behind.
On the other hand, the behavior of the minor murderer is also very unpredictable, including the motive for the murder and the way of covering up the murder, which are not adult-like.
If it were an adult, let alone whether he would kill someone just for the sake of cleaning and tidying up the room, he would not dare to throw away the pillow for fear of relatives finding out, and would only scrub and wash it desperately. When abandoning the body, he would not have been so hasty to abandon it on the side of the road, leaving such deep motorcycle tracks.
But to say that the two were brainless is because they not only knew how to abandon the body, but also knew how to strip the victim's clothes and pants to make it look like she had been sexually assaulted.
However, Jiang Yuan's attention to these details has been very low.
For Sun Jianyu and Liu Mingxue, their ability to resist interrogation is very weak. Based on the current evidence, it is enough to make them repeat the details dozens of times.
Yu Wenshu and others were even more satisfied. After receiving Jiang Yuan's report, they kept saying, "I didn't expect that this case was committed by two minors. The case in our Changyang City is still not perverted enough..."
"It's already quite perverted." Shen Yaowei accompanied the whole process. Although he didn't play any role, he knew the case very well. He said: "Two minors quarreled over a small matter, and then the best friend and her boyfriend killed the person together. They also abandoned the body afterwards. If this case is not solved, in another 10 years, I don't know how many victims will suffer."
Yu Wenshu nodded: "Not completely abnormal."
"Thanks to Captain Jiang, our case team has not been able to move forward." Cao Chujun sighed. He is an old captain who is about to retire. He has become less concerned about things like face. When he is about to leave, he is more concerned about solving a few big cases to appease himself who has been a policeman for 40 years.
Jiang Yuan smiled and declined. Although he thought the case was not difficult, he couldn't say that in front of Cao Chujun, the former head of the special task force.
Cao Chujun saw it. Old detectives all have a vision that may not necessarily solve the case, but can see through people's hearts.
Cao Chujun's heart was warmed, and before Yu Wenshu could speak, he struck while the iron was hot and said, "Captain Jiang, there are actually a lot of abnormal cases, especially the backlog of cases in the past. Some of the cases are too old, so it is difficult to solve them..."
This is straight hook fishing.
Cao Chujun looked at Jiang Yuan enthusiastically.
Jiang Yuan smiled, looked at Yu Wenshu, and said, "Actually, I don't pursue any perverted cases. Solving some normal murder cases will give me a great sense of accomplishment."
Yu Wenshu said at this time: "You have more than 30 people with you. It's too cost-effective to handle ordinary cases."
Jiang Yuan was stunned for a moment. He hadn't thought about this.
Cao Chujun chuckled twice, looked at Yu Wenshu, and said in a more formal tone, "Speaking of these perverted cases, I think the previous 303 case is qualified."
"Case 303..." Yu Wenshu quickly recalled: "The deceased were 31-year-old Zhao Qian, 28-year-old Qin Jijian, and 35-year-old Gu Daxu... The three were hacked to death at Zhao Qian's home while having a threesome?"
"Yes, it's this case. You still remember the name of the deceased. That's amazing..." Cao Chujun flattered the Changyang City Criminal Police Detachment in the most vulgar way, causing Yu Wenshu to laugh.
"Case 303 is indeed a rather perverted case. The murderer is quite skilled and brutal. It has not been solved for seven or eight years. It is time to re-examine it." Yu Wenshu said, looking at Jiang Yuan, "I guarantee that the scale of this case is much larger than the previous one."
"In fact, there is no need to pursue the perversion or scale of the case." Jiang Yuan sighed.
"This case is quite amazing." Cao Chujun changed the subject and said, "The murderer in this case entered through the balcony's security window, which he pried open with his hands. After entering, the murderer killed three people in a row, cleaned them up and left. His movements were very neat and his skills were very good. No bloody footprints or the murderer's DNA were found at the scene."
"Are all three of you 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 had more than two sexual partners, and some may be relatively secretive. The case has not been able to identify the suspect."
