Chapter 814: Deadly Instrument

early morning.

After a good wash and a good sleep, Lei Xin appeared in front of Jiang Yuan in high spirits.

The captains of the criminal police brigade are all veteran strivers who stay up late all year round. Even if they come back from the garbage mountain, they will not be spread out on the ground like ordinary garbage and cannot be pulled out.

"Captain Jiang, give the order. We are all ready." Lei Xin has obviously mobilized himself.

Several other criminal policemen were also mobilized by Lei Xin, their expressions were relieved and as calm as corpses.

"Actually, there is no need for so many people." Jiang Yuan counted the heads and then said: "I originally planned to send police officers from the special backlog class to do the work. You just need to coordinate with the two of them..."

"There is no reason to just ask you to do things. It's just a matter of climbing a garbage mountain. It's not like sleeping in a garbage mountain. You can do whatever you need to do." Lei Xin said boldly.

A criminal police officer who was mobilized smiled and said: "If I go home and sleep, my wife will be sleeping in a mountain of garbage."

"My wife is used to it." Lei Xin glanced at him nonchalantly and said, "Have you been sleeping in the office these days?"

"Yes, I was thinking that during these few days when I go to the garbage mountain, I don't want to go home and torment my own people!"

Liu Jinghui was beside him and shook his head when he heard: "If you act like this, you won't be able to go home for a week. Even if you take a shower every day, you won't be able to wash away the smell of the garbage mountain. I haven't smelled it. If someone comes close to you every other week, she will still find you smell bad, but you only need to go back and sleep for one night, at most, for two or three days, and she will get used to it.”

The detective who was complaining just now listened and said seriously: "What you said makes sense, but..."

Liu Jinghui asked: "You sleep in the work dormitory? How do you feel about the smell of smelly feet?"

“That must smell bad.

"Can you sleep even if it smells bad? Do you feel that the smell is getting weaker day by day?"

The detective who had a wife felt nauseated: "I can still smell it."

"To be honest, the smell in your dormitory is really strong. It's better than the garbage mountain. But you people who climbed out of the garbage mountain are all sleeping in the dormitory. You can't smell the smell. Think about it. ?" Liu Jinghui grasped the wisdom of the policeman on the other side and said, "This is just like a fisherman."

"Fishermen?"

Liu Jinghui said: "When you go to the seaside pier, you will feel that the wind has a fishy smell when you first go there, but the fishermen will tell you that fish will have a little fishy smell after being left for a long time, but other things will not. Similarly, People on the grassland will not feel the smell of a sheepskin jacket that has not been washed for a year. When you walk into a store where you eat stinky mandarin fish, you will smell the smell. They say it is fragrant. Now there is a store where you can eat durian. , some people cover their noses and leave, and some people come in with bleeding eyes..."

"No wonder..." The detective who had a wife seemed to be enlightened by his wisdom and nodded in a daze: "I said that sometimes when I go back to the dormitory, I will ask about a sweet smell. They said it is the smell of instant noodles..."

Liu Jinghui's pearls of wisdom were scattered all over the floor: "That's not what I meant..."

Jiang Yuan coughed twice: "Let's talk about the case."

A group of people quickly sat down around him.

"Project 802 is also a murder case this year. There are really many cases in Qinghe this year." Jiang Yuan opened the file and commented casually.

Lei Xin shook his head and smiled bitterly.

"No wonder the Lei Brigade didn't answer when Lao Huang talked about the combat power rankings. Liu Jinghui laughed at the excitement.

Jiang Yuan did not let Liu Jinghui continue to let himself go, and brought back the topic again, saying: "The victim was hit on the head with a blunt instrument, and there were bamboo shavings remaining. The crime scene was in the victim's backyard, and moso bamboo used for construction was found at the scene. , but after comparison, it was not confirmed as a murder weapon. In addition, many bamboo items in the house were also inspected and could not be identified as murder weapons..."

Jiang Yuan briefly explained the situation and then continued: "The deceased Wang Shouhu was 52 years old and in good health. There were no signs of struggle or defensive injuries on his body. It can basically be considered that the crime was committed by an acquaintance... I see you have also checked the related persons. ,not found?"

Lei Xin shook his head helplessly: "There are no suspects who meet the conditions. The local rural population is already very small. They are mainly old people and middle-aged and elderly people. People like the victims are relatively young, and there are a few young people. , like the victim’s own son, most of them stay at home, there are no witnesses, and there is no motive for committing the crime.”

Many murder cases in rural areas are simple and easy, and difficult and difficult. Compared with cities, relationships in rural areas are stable and hidden. Many grudges are formed over time. The final "trigger point" may be a very, very small thing. It is often the murderer who cares about it very much, but it is far from being called a crime. It is the reason for killing.

On the other hand, surveillance, mobile phones, and even DNA and fingerprints may not be useful in this environment. For example, in a burglary case in the city, finding an unfamiliar fingerprint on the window can be regarded as a suspect, but in the village, it is not surprising to find someone's fingerprint on the window of a house.

"Can forensic botany be used in this case?" Lei Xin was full of expectations. They actually had common technical methods, but forensic botany was pretty much exclusive to Jiang Yuan. Not only are there an absolute shortage of technicians who can use this technique, but this technique also takes a long time. Even Lei Xin and the others can't get in line if they want to.

Jiang Yuan was amused, turned around and said helplessly: "I should tell you about forensic botany when I have time. You just have some bamboo shavings here, which has nothing to do with forensic botany. Forensic botany requires a variety of plants. Look at their plant atlas. For a single plant, just compare the mitochondrial DNA. Besides, this bamboo shavings should come from tools."

Lei Xin nodded, not quite understanding.

Jiang Yuan thought that he could ask Pang Jidong and others to come and do some popular science later.

This idea flashed through his mind, and Jiang Yuan continued: "Two days ago, when I was free, I speculated about the murder weapon in this case. First of all, the bamboo stick you speculated in the investigation file must be wrong."

"Wrong?" Lei Xin couldn't say it was unexpected, but he was a little helpless. He thought to himself that the forensic doctor Niu was only studying paper towels all day long, and he was wrong twice about the murder weapon.

Jiang Yuan drank water strategically, and then said: "This is not entirely to blame forensic doctor Niu, he is also a guess... Well, in short, if the bamboo stick hits the head, the head will indeed form a fracture wound, but the scalp will not be completely severed, especially the skull, which will not form such a comminuted fracture, and the skull injury will not be so serious. There is a saying that "bamboo hits the hollow", which refers to the traces of stick damage. Judging from the photos, I think the reason why the bamboo stick is the murder weapon is not sufficient, and the assumption is not established."

Judging the murder tool is also a very difficult project. Generally speaking, the LV2 level can only judge a sharp weapon or a blunt weapon, plus some common things. This is the limit of the level of forensic doctor Niu. He actually guessed several types of tools, and it cannot be said that he was completely wrong.

But it must be said that in terms of tool mark judgment, being able to have a LV2 level is already an elite forensic doctor. People have different abilities, especially in the field of forensics. The wounds and ways of death of many people are actually not typical. You must judge a result. You have never seen it or read similar books, and the deceased is a maverick. What can you do?

The main reason is that forensic reports rarely give negative results. In fact, some forensic autopsies have no results. "No solution" is actually the answer.

In contrast, Jiang Yuan's tool mark identification is LV6, which is much higher, so he can easily give the result.

Jiang Yuan continued: "Regarding the murder weapon, because the deceased Wang Shouhu's skull has a comminuted fracture and even a certain degree of depression, bamboo shavings are mixed in the bone fragments, indicating that the murder weapon should be a high-momentum blunt tool."

"High momentum?" Liu Jinghui translated: "High weight, high-speed blunt tool?"

"Yes."

Liu Jinghui couldn't help thinking.

Jiang Yuan had been watching for two days, and without waiting for him, he gave the answer directly, saying: "A pounding hammer or a hoe. Considering the bamboo shavings, the murder weapon is most likely a hoe."

Jiang Yuan gestured and said: "A bamboo-handled hoe, hitting the head of the deceased with the back of the hoe..."

Everyone present could only nod.

Jiang Yuan said again: "Now it depends on whose hoe it is. Let's first find out if anyone has a replacement hoe. If none of them have one, then bring back the bamboo-handled hoes from each family for inspection."

"This is good, this is good!" Lei Xin felt enlightened, and the rash on his body was no longer itchy.

I will be hospitalized tomorrow and have surgery the day after tomorrow. I heard that I will be discharged in three days. I'm not sure how many days I need to rest... I probably won't update these days, hope you understand. Meow~
