Chapter 250 Saw Blade
Chapter 251 Saw Blade
Although only one victim was identified, or rather, one victim was identified, everyone was already in high spirits.
In several groups, more people were talking.
In the "Gray Chapter Group" that Jiang Yuan was pulled into, someone started chatting happily:
Trace Examination Li Rui: [I feel hopeful. Now that the source of the corpse has been identified, we can search for the activity track on the day of the disappearance. ]
Current Investigation Zhang Mingyuan: [Don't be so optimistic. She has been missing for three years and four months. Only her family members can still remember a little. If you ask people around her, they can't remember it. ]
Photo Detective Fu Quanxian: [Didn't you actively look for her when she disappeared? Normal people, if someone around them is missing and is questioned, they will definitely remember it clearly. ]
Current Investigation Zhang Mingyuan: [When she disappeared, her parents were not around and went to the countryside. The victim had no job and stayed at home. Well, it's called flexible employment now, so she had no colleagues. Four days after she disappeared, her parents called the police after they couldn't get through the phone many times. 】
Forensic doctor Niu Lihuang: [(ω) The victim had cervical spondylosis and lumbar disc herniation, all occupational diseases caused by working at a desk, but he didn't have a job? 】
Investigator Zhang Mingyuan: [It must be because of playing games. 】
Forensic doctor Niu Lihuang: [Fuck, forensic doctors can't do it anymore, how can they judge the life and occupation scenes? 】
Investigator Zhang Mingyuan: [Fortunately, we found the victim's accessories, Jiang Yuan is still good, otherwise, it is not certain whether we can find the victim this time. 】
Picture detective Fu Quanxian: [So now, are there any clues about the motorcycle? Or are the clues broken? 】
Investigator Zhang Mingyuan: [We are still looking, and we can't limit it to the victim's living area, this person's living area is very narrow. 】
A group of people were chatting, from optimism to pessimism, and soon they stopped chatting.
Jiang Yuan also frowned. He had imagined the identity of the victim, but he didn't have any firm ideas.
However, his initial thought was that the victim was a white-collar worker or civil servant, at least the type who worked at a desk in an office. Who would have thought that a girl in her twenties, who played games seriously, could actually get so many diseases.
After browsing the phone, Jiang Yuan came back to his senses, sighed secretly, and looked at the body again.
According to his original idea, if the source of the corpse or the crime scene was found, the probability of finding the murderer would be very high.
Just for the unsolved murders, there is a lot of evidence now.
However, if you can't find it, you can't find it. Especially during the time when the victim's home was found, if there were new clues, maybe the murderer could be locked directly, but if not, the value of this clue would be greatly reduced.
The criminal police are still working hard in the local area, and by checking the motorcycle, the status of the person at the time of disappearance, the interpersonal relationship of the victim, etc., they may be able to find some clues.
But from Jiang Yuan's point of view, the best evidence is always the body itself.
"The King of Evidence" shows the rich information provided by the body, but it is a bit too difficult to obtain.
However, compared with the first three bodies, the fourth body seemed to have more to say - this was purely Jiang Yuan's feeling. If he had to describe it, the fourth body looked messier and was handled more carelessly.
From the perspective of time, the fourth body was also killed a long time ago. Jiang Yuan judged it to be 4 years ago.
In other words, the victim was killed by the murderer earlier.
Was the handling not perfect?
Or did an accident occur during the handling process?
Jiang Yuan looked for clues carefully with expectation in his heart.
In fact, it is normal for the murderer to encounter some unexpected situations during the dismemberment process.
When slaughtering pigs during the Spring Festival in the countryside, the butcher who has been slaughtering pigs for a lifetime dare not say that he will not have any accidents.
Moreover, the murderer is under great psychological pressure, the operation location is often not very comfortable, and the line of sight is restricted. It is normal for accidents to occur. Some murderers even learned to wear latex gloves, but the gloves were cut into the body.
Jiang Yuan did not find any particularly useful evidence for the first three bodies, but looking at the fourth one, Jiang Yuan hoped to gain something.
He did not examine the bodies in order, but followed his heart and took the large bones to look at first.
This inspection took more than an hour.
During this period, other forensic doctors also came to look at the bones, but everyone focused on different points, and the direction of attention and judgment was also different.
Jiang Yuan watched silently, and when he saw the cut radius and humerus, he couldn't help but stop.
This time, what attracted him was the cross section of the bones.
The bones were cut with a saw, which was nothing new. Many dismemberment monsters like to use saws, including Wang Guoshan in the reservoir dumping case, who also used a saw to dismember the body.
Compared with dismemberment using axes, machetes, etc., using a saw to dismember the body consumes less effort, the number of dismembered pieces is also more, and the average weight of each piece is also smaller.
Jiang Yuan had seen many corpses that were cut up with saws, but for corpse No. 4, its cross section had changed.
What kind of changes?
Jiang Yuan took out several sternums and ribs and compared them with the humerus and radius. He could see that the former had a smoother cross section, while the latter had not only more serious cutting marks, but also obvious saw marks.
In addition, the step marks on the humerus and radius are obvious, 4 mm from the cross section, and 4 mm in length. The sternum and ribs appear flatter and clearer.
All this points to one problem: the murderer changed his saw.
Whether he cut the sternum first or the arm first, he changed the saw.
Maybe a saw is broken, maybe the saw blade is broken, maybe he feels that the saw he is using is not powerful, no matter what the reason is, in short, the murderer changed the saw during the process of using the saw to dismember the body, at least it was Saw blade replaced.
But whether it was changing the saw or the saw blade, it further revealed an answer: the murderer completed the dismemberment at a fixed location.
The reason for this inference is that the murderer must have used a high-power saw, most likely a chain saw.
The size and weight of a chain saw are not small, it must be about 10 kilograms, and its saw blade should be called a saw chain, which is similar to a bicycle chain and weighs several kilograms.
Jiang Yuan felt that a normal corpse-dismembering monster would not carry two chain saws, or one chain saw and another chain.
If the corpse-dismembering monster has a phobia of chain breaks, wouldn't it be more reasonable and appropriate to simply replace the chain saw with a saw chain based on his rigor?
This thing is often used to saw wood and trees, and it is made of special steel. It can be sharpened and reused after hundreds of cuts, and it is not so easy to break and damage.
Buy a new one online and put it on. After splitting two people, maybe you can return it to the boss.
Therefore, a more reasonable explanation for changing the saw or saw blade on corpse source No. 4 is that the murderer dismembered the body on his own territory.
This way, if you encounter a problem, you can replace the saw or saw blade smoothly and easily.
If so, it overturns another hypothesis, that is, the murderer deliberately carried saws and other crime tools to commit crimes far away from his place of residence or work.
In other words, the murderer’s place of residence or work should be near the crime scene.
That is, near the residence of Feng Xiaoyan, deceased No. 3!
Jiang Yuan figured this out and immediately called Huang Qiangmin.
Huang Qiangmin on the other side didn't rest either. After listening to Jiang Yuan's reasoning with great anticipation, he was slightly silent.
"Is there a problem?" Jiang Yuan felt something was wrong.
"We have already scanned Fang Jinxiang's motorcycle, and no suspects have been identified." Huang Qiangmin sighed.
Jiang Yuan was a little surprised: "Did they sweep so fast? Then... around Fang Jinxiang? A rural area relatively close to Feng Xiaoyan?"
"It's possible. But there aren't as many motorcycles here as in Zifeng Town." Huang Qiangmin paused and said, "Maybe they come from other towns twenty or thirty kilometers away?"
"It's a little far. Besides, carrying one chain saw on a motorcycle is too much. How about two chain saws, or one chain saw and two chains? It's too tiring."
"That's true." Huang Qiangmin paused for a while and said, "It's possible that Feng Xiaoyan could move, but it's really unlikely that she would be alone for dozens of kilometers."
Huang Qiangmin said, denying himself.
"So, there is a high probability that the murderer is in Fang Jinxiang, or in the surrounding area. It's a pity that the source of the other corpses cannot be found. Otherwise..." Huang Qiangmin was a little annoyed, and then said: "This dismemberment tool is We have been paying attention to it, but we have found nothing. Well, your discovery is still very valuable. I will report it to Director Xu and we still need to strengthen the search and investigation here. "
Jiang Yuan responded and hung up the phone, feeling a little tired.
It is said that the scope has been reduced, but a radius of ten kilometers or a radius of fifteen kilometers is not small. If you have enough time, then you can investigate carefully bit by bit, and the possibility of harvesting is very high.
However, the investigation is the most time-consuming.
I went to bed at 5 o'clock in the morning yesterday and woke up at 7 or 8 o'clock in the morning. I couldn't fall asleep or code. I waited until 10 o'clock to fall asleep again. When I woke up, it was dinner time. I feel like my life is a bit muddled...
