civil forensic

Chapter 251 Saw Blade
Although only one victim has been identified, or rather, the identification of a victim has already made everyone's emotions high.

In several groups, there were obviously more people talking.

In the "Grey Chapter Group" that Jiang Yuan was drawn into, someone chatted cheerfully:

Trace Inspection Li Rui: [I feel hopeful. Once the source of the corpse is determined, we can search for the trace of the activities on the day of the disappearance. 】

Present survey Zhang Mingyuan: [Don't be so optimistic, I have been missing for three years and four months, only my family members can remember a little bit, and if I ask people around me, I can't remember anything. 】

Figure detective Fu Quanxian: [Didn't you actively look for someone when you disappeared?Normal people, if someone around them is missing and they are questioned, they will definitely remember it fresh. 】

Present survey Zhang Mingyuan: [When she disappeared, her parents were not around, and she went to the countryside.The victim didn't have a job and stayed at home. Well, it's called flexible employment now, so she has no colleagues. Four days after she disappeared, her parents couldn't get through the phone many times before she called the police. 】

Forensic doctor Niu Lihuang: [(ω) The victim suffered from cervical spondylosis and herniated lumbar intervertebral disc, all of which were occupational diseases of working at a desk, but did he not work? 】

Currently surveying Zhang Mingyuan: [I played games. 】

Forensic doctor Niu Lihuang: [Fuck, forensic doctor can't do it anymore, how can you judge the life and occupation scene? 】

Now inspecting Zhang Mingyuan: [Fortunately, the victim's accessories were found, Jiang Yuan is still very good, otherwise, it is not certain whether the victim will be found in this wave. 】

Figure detective Fu Quanxian: 【Now, is there any clue about the motorcycle?Or is the thread broken? 】

Currently surveying Zhang Mingyuan: [I'm still looking, and it can't be limited to the victim's living area. This person's living area is very narrow. 】

A group of people chatted from optimism to pessimism, and soon they stopped chatting.

Jiang Yuan also frowned.He had imagined the identity of the victim, but had no firm idea.

However, his initial thought was that the victim was a white-collar worker or a civil servant, at least the type who worked at a desk in an office.Who would have imagined that a girl in her twenties who seriously plays games can suffer from so many diseases.

After swiping the phone, Jiang Yuan came back to his senses, sighed secretly, and looked at the corpse again.

Based on his original thinking, if he found the source of the corpse, or the place where the crime took place, the probability of finding the murderer would be very high.

Taking the backlog of homicide cases as an example, there is a lot of evidence now.

However, if you can't find it, you can't find it.Especially during the period of finding the victim's home, if there is a new clue, maybe the murderer can be locked directly, but if not, the value of this clue will be greatly reduced.

The criminal police are still working hard on the ground. By checking the motorcycle, checking the situation of the missing person, checking the victim's interpersonal relationship, etc., they may be able to find some clues.

But from Jiang Yuan's point of view, the best evidence is always the corpse itself.

The "King of Evidence" shows that the information provided by the corpse is rich, but it is too difficult to obtain it.

However, compared with the first three corpses, the fourth corpse seemed to have more to say—this was purely Jiang Yuan's feeling.If he had to describe it, the fourth corpse was messier and handled more sloppily.

From the time point of view, the death time of the fourth body was relatively long, and Jiang Yuan's judgment was 4 years ago.

It is equivalent to saying that the victim was killed earlier by the murderer.

Not perfect enough?
Or did you encounter an accident during the processing?

With anticipation in his heart, Jiang Yuan carefully searched for clues.

In fact, it is normal for the murderer to have some unexpected situations during the process of dismembering the body.

When pigs are slaughtered during the Chinese New Year in the countryside, the butcher who has been invited to kill pigs all his life dare not say that he will not have any accidents.

What's more, the murderer's psychological pressure is high, the operating place is often not very comfortable, and the sight line is restricted. It is normal for unexpected situations to occur.Some murderers also learned to wear latex gloves and so on, and the gloves were cut into the corpses.

For the first three corpses, Jiang Yuan did not find any particularly useful evidence, but looking at the appearance of the fourth corpse, Jiang Yuan hoped to gain something.

He also didn't inspect the corpses in order, but followed his heart, first took the large bones and looked through them.

From this point of view, it was 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 directions of attention and judgment were also different.

Jiang Yuan watched silently, and couldn't help but stop when he saw the cut radius and humerus all the way.

What attracted him this time was the section of the bone.

The bones were cut with a saw, which is nothing new.Many dismemberment monsters like to use saws, including Wang Guoshan in the case of dumping corpses in the reservoir, which also uses saws to dismember corpses.

Compared with those who use axes and machetes to dismember corpses, using saws to dismember corpses consumes less effort, and the number of dismembered corpses is also more, and the average weight of each piece is also smaller.

Jiang Yuan also saw a lot of corpses that were dismembered with a saw, but as far as the No. [-] corpse source was concerned, its section had changed.

what kind of change?
Jiang Yuan took out several pieces of sternum and ribs, and compared them with the humerus and radius. At this time, he could find that the section of the former was smoother and smoother, while the latter had not only serious cutting marks, but also obvious saw marks.

In addition, the traces of the step pattern of the humerus and radius are obvious, 4 mm away from the section, and the length is also 4 mm.The sternum and ribs appear smoother and clearer.

All of this illustrates one problem: the murderer changed the saw.

Regardless of whether he cut the sternum first or the arm first, he changed the saw.

Maybe a saw was broken, maybe the saw blade was broken, maybe the saw he was using wasn't strong enough, whatever the reason, in short, the murderer replaced the saw in the process of dismembering the body with the saw, at least Saw blade replaced.

But whether it is changing the saw or the saw blade, it further reveals 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 chainsaw.

The size and weight of the chain saw is not small, it must have the appearance of 10 kilograms, and its saw blade should be called a saw chain, which is a thing that weighs several kilograms similar to a bicycle chain.

Jiang Yuan felt that a normal dismemberer should not carry two chainsaws, or one chainsaw plus another chain.

If the corpse monster has a fear of chain breaking, wouldn't it be more reasonable and appropriate to directly replace the chain saw with a saw chain with 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 a few hundred saws. It is not so easy to break and damage.

Buy a new one from the Internet and replace it. After splitting two people, maybe you can return it to the boss.

Therefore, on the No. [-] corpse source, the more reasonable explanation is that the murderer is dismembering the corpse on his own territory if the saw or saw blade is replaced.

In this way, if there is a problem, the saw or saw blade can be replaced smoothly and easily.

If it comes, it overturns another hypothesis, that is, the murderer deliberately carries saws and other crime tools, and commits crimes far away from the 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, the third deceased!

Jiang Yuan figured this out and immediately called Huang Qiangmin.

Huang Qiangmin on the other end didn't rest either, and listened to Jiang Yuan's reasoning with great expectation, but was a little silent.

"Is there a problem?" Jiang Yuan felt wrong.

"Fang Jinxiang's motorcycle has already been scanned by us, and no suspects have been screened out." Huang Qiangmin sighed.

Jiang Yuan was a little surprised: "Is the sweep so fast? Then... around Fang Jinxiang? The villages that are closer to Feng Xiaoyan?"

"It's also possible. But there are not as many motorcycles here as in Zifeng Town." Huang Qiangmin paused and said, "Maybe they came from other villages and towns twenty or thirty kilometers away?"

"It's a little bit far away. Besides, it's enough to carry a chainsaw on a motorcycle. Two chainsaws, or one chainsaw and two chains? It's too tiring."

"That's true." Huang Qiangmin paused for a while, and said: "Feng Xiaoyan may also move, but it is really unlikely that she will leave dozens of kilometers alone."

As Huang Qiangmin said that, he denied himself.

"So, the murderer is in Fangjin Township, or there is a very high probability that the murderer is in the surrounding area. Unfortunately, the sources of the other corpses cannot be found, otherwise..." Huang Qiangmin was a little annoyed, and then said: "The corpse dissection tool is here. We have been paying attention to one piece, but found nothing. Well, your discovery is still very valuable, I will report it to Xu Chu, 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 there is enough time, then a little bit of careful investigation, the possibility of harvesting is very high.

But the investigation is the most time-consuming.

　I went to bed at 5 o'clock in the morning yesterday, and woke up at seven or eight o'clock in the morning. I couldn't fall asleep, and I couldn't code. I fell asleep again at 10 o'clock. When I woke up, it was dinner time.Feeling a little muddled...
