National Forensic Doctor

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 certain criminal policeman 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 do 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 think you stink. But as long as you go back to sleep for one night, or two or three days at most, 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 sick: "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 pearl of wisdom and turned on the wisdom of the criminal policeman on the opposite side: "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 sheepskin jackets that have 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 walk away, 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 Team Lei 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 traces 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 grievances 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 not 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 later 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. Looking at their plant map, for a single plant, just compare the mitochondrial DNA. Furthermore, the bamboo chips should come from tools."

Lei Xin nodded in understanding.

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

This thought passed by, and Jiang Yuan continued: "Two days ago, when I was free, I speculated on the death tool in this case. First of all, the bamboo stick guessed in your investigation file must be wrong. "

"Wrong?" Lei Xin couldn't say it was an accident, but he was a little helpless. He thought to himself, Forensic Niu only studied tissues every day, but he made the mistake twice just by looking at the murder weapon.

Jiang Yuan drank water tactically, and then said: "This is not entirely to blame Niu Forensic, he is also a guess... Well, in short, if the bamboo stick hits the head, the head will indeed form a contusion wound, but the scalp will not Full-thickness fractures, especially in the skull, will not form such comminuted fractures, and the skull damage will not be so serious. There is a saying called "Bamboo hits hollow", which refers to the traces of stick damage, and from the photo , I think there is insufficient reason for the bamboo stick to be the murder weapon, and the assumption is not valid."

Judging death tools is also a very difficult project. Generally speaking, the LV2 level can only judge sharp and blunt weapons, plus some common things. This is the limit of Niu Forensic's level. He actually guessed several types. type of tool, it cannot be said that it is completely wrong.

But it has to be said that in terms of tool mark judgment, someone with LV2 level is already an elite forensic scientist. People's abilities vary, especially in the field of forensic medicine. In fact, many people's wounds and death methods are not typical. You must judge a result. I have never seen it or read similar books, and the deceased was a person. What can you do if you are a maverick?

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

In comparison, Jiang Yuan's tool mark identification was LV6, which was much higher, so he could easily give the result.

Just listen to Jiang Yuan continue: "As for the murder weapon, because the skull of the deceased Wang Shouhu had a comminuted fracture and even a certain degree of dent, and the bamboo chips were mixed with the bone fragments, it means that the death tool should be a high-momentum blunt tool. .”

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

"right."

Liu Jinghui couldn't help but think.

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

Jiang Yuan gestured and said: "Use the bamboo-handled hoe to hit the deceased's head with the back of the hoe..."

Everyone here could only nod.

Jiang Yuan said again: "Now it depends on whose hoe it is. First, check if each store has a replacement hoe. If not, then bring back the bamboo-handled hoe from each store for inspection."

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

I will be hospitalized tomorrow and have surgery the day after tomorrow. It is said that I will be discharged in three days. I am not sure how many days I need to rest... I will not update in the past few days. I hope you understand. Meow~
