National Forensic Doctor

"Captain Jiang, we have now identified 17 local missing people, who are male, in their thirties, and about 1.7 meters tall. Are we sending people to the door now?" Lei Xin simply asked directly, not caring about the captain. title.

What he said were the results of the investigation by the criminal police. These 17 people are now the key targets of investigation. Following the principle of visiting the door for major cases and calling for minor cases, it is inevitable to investigate more carefully, or even come to the door for a second time to ask something. There is a possibility of alerting the enemy. At this time, we have to see what evidence we have.

For this kind of case, the prudent approach is to at least have something before proceeding to the next step. It is best to come to the door in a targeted manner and bring it back if the conditions are met. Otherwise, the suspect who caused the murder is likely to be in a state of confusion. The second time he meets the police, he may suddenly flee.

Liu Jinghui smiled and said, "Your conditions are quite generous."

Lei Xin sneered: "I don't think there are many people."

Liu Jinghui said: "The victim died and dumped his body six years ago. Normally, if he did not go home during the New Year, his family should report the crime. Two years is too long. One year should be enough."

He said and looked at Jiang Yuan.

Jiang Yuan nodded and said: "The age is based on 37 years old. If you are worried, just give it a year plus or minus."

"In one year, at the time of the incident, the victim's age was 36 to 38 years old. His biological age? A little nervous, right?" Lei Xin was a little uneasy, mainly because he felt that it was okay to relax a little and just investigate more. Just an individual.

Jiang Yuan smiled and said: "Actually, that's enough. If you're worried, just relax a little and base it on 37 years old."

"Then I will relax the age of three, because some people are counted as one year old or something. In addition, I will make a separate table with an increase or decrease of one year." Lei Xin said and asked the detective on the table next to him to make a new table.

He said he was obedient, and he also wanted to be obedient in his heart. However, the answer Jiang Yuan gave was too extreme. It's like a farmer buying a tractor online to plow the land, but when the express package is opened, it turns out to be a Lamborghini tractor. It's not that it's not good, it's not that he doesn't like it, it's just that he's a little confused.

The instructor winked at Niudong, then smiled at Jiang Yuan, and said: "There are 17 people in total. In fact, it is enough to check them all. The sifting is too fine, and the people below have nothing to do..."

Liu Jinghui said: "The 17 people are all missing locally. If we can't find them, we need to check the surrounding areas, or even check the floating population in a larger area. It would be beneficial to be stricter."

"That's true. There are more people checking the surrounding area." The instructor then became serious.

Liu Jinghui smiled and said nothing more.

Liu Jinghui is not like Jiang Yuan, who can use hard skills to carry it out. During his tour across the province, he often took the route of checking for gaps. Especially in the early years, when investigating cases, it is actually necessary to consider the impact of other aspects. Some units, some areas, and some people may not be able to investigate, or at least they must be investigated later. This kind of decision will not be explained by the local criminal police captain, nor does it need to be explained.

There is nothing to avoid in this regard. In the past, the Chinese thought that Europe and the United States were models of judicial fairness. Their own investigations were affected by politics, and they even felt inferior. Now that they know more about it, they know that everyone is equal before the law. Obviously, Europe and the United States are It was not done.

According to Liu Jinghui's thinking model, since Jiang Yuan's technology is credible, you will lose money if you draw a large circle, especially if it involves other privileged units. The smaller the circle you draw, the more likely it will be. Very communicative. Just like the 37-year-old line, if it involves the military, it is relatively easy to investigate because there are only a few people. But if the line is drawn to a broad range like the 30s, the scope of investigation would be much larger.

The reason why Tao Lu, the head of the criminal police detachment in Beijing, including Qi Changye and others like Jiang Yuan so much, has a lot to do with the small and accurate circle he draws, which reduces many conflicts outside the investigation.

Of course, this is more difficult for a district bureau political commissar to realize.

While several people were talking, a new form was printed out. The form of 17 people was condensed into 4 people, and the font of one of them was bolded.

Lei Xin licked his lips and said: "There are four people left. If according to what Captain Jiang said, around 37 years old is the standard, there will be only one missing person within the current period.

This is a missing person within the jurisdiction of Qinghe City. The following counties, towns and townships are not included. For example, Ningtai County is a county in Qinghe City in terms of administrative divisions.

In addition, the current floating population is also a huge problem. Many people may come to Qinghe City for work, tourism or to visit relatives and friends. When the relevant person discovers that they are missing, they may report the case in their own district and may not necessarily know who they are. The city or route when missing is one of the reasons why many missing persons are difficult to find.

But as far as the current investigation strategy is concerned, several people are ready to check the population in the jurisdiction first, so the only missing person seems a bit outstanding.

"Then we'll check these four people first. I'll personally lead the team and go to the 37-year-old victim's home to inquire." Lei Xin quickly made arrangements.

"Is it a rural area on the outskirts of the city? Let me go too." Jiang Yuan looked at the distance and felt that it was only an hour's drive away.

Lei Xin was stunned for a moment, then nodded without hesitation: "That's the best. I can rest assured that Captain Jiang is here."

As he said that, he silently doubled the number of people heading out and borrowed two cars of people from the criminal police team next door.

Niudong followed without hesitation.

It is normal for a forensic doctor to show up at a scene. Of course, he has not experienced much of showing up at a scene where no one is dead.

After getting in the car, Liu Jinghui asked Jiang Yuan, "Is age really such a big deal?"

Jiang Yuan said "Yes" and said: "Basically."

"Didn't the forensic doctor Niu make a mistake?" Liu Jinghui was also curious. There were only Mu Zhiyang, Wang Chuanxing, Jiang Yuan and him in the car, so it was easy to ask questions.

Jiang Yuandao: "Forensic anthropology is relatively complicated. I have looked at other bones and the conclusions are consistent."

Because there was a problem in judging the age of this corpse, Jiang Yuan carefully identified it. Although he said that what he told Niudong was about age determination at the pubic symphysis, Jiang Yuan actually made age inferences from other bones besides the pubic symphysis.

Skull teeth, sternum ribs, vertebrae, limb bones and even phalanges can all be used to judge age. It can also be further refined. For example, the sternum can be used to judge age based on depressions, bulges and textures.

Combining these bones, Jiang Yuan concluded that the ages of the corpses were almost the same. It fluctuates by one year, and the margin given can be said to be sufficient.

When discussing the age of the corpse just now, Jiang Yuan did not discuss this with Niudong because the pubic symphysis is the easiest part to judge age in anthropology. It can directly point out the problem. In comparison, it is the most direct part. s solution. The other parts of the verbosity are all included in basic textbooks, and the details cannot be taught in just a few verbose sentences.

After cheating for a long time, Jiang Yuan has a relatively clear definition of which technologies are easier to explain and which technologies do not require explanation.

Liu Jinghui didn't understand so much and just nodded silently. He doesn't need to know the forensic part, but he also needs to know the boundaries of Jiang Yuan's abilities, which is obviously helpful for reasoning.

After driving for 40 minutes, we stopped beside a county road.

Various slogans are painted on the wall of a two-story village committee, and flowers and plants are planted in front of the door. It looks a bit like the office building in 2000.

The criminal police who arrived early had already called over the village cadres and village secretaries. They waited for everyone to arrive and then acted according to the orders.

At this time, Jiang Yuan followed Lei Xin and others to their destination.

Mu Zhiyang wore stab-proof clothing, a small transparent buckler hung on his left hand, and his tactical belt hung heavily around his waist. He followed Jiang Yuan without saying a word.

There were more than a dozen criminal policemen accompanying him, and together with the people from the village committee, it was quite a force.

"The missing person here is named Fang Delu. He is of the same age. The last known location was working in Qinghe City. His wife is divorced and he has a son who followed his mother to Changyang City." Lei Xin briefly introduced, and then said: "Fang Fulu's parents have already passed away. He passed away. It was his eldest brother Fang Defu who reported the case. Fang Defu is three years older than Fang Delu and is 46 years old this year. Let’s go to his house now.”

Liu Jinghui said as he walked: "Telford Lu, does the victim have any brothers or sisters?"

"There is also a younger brother, the third elder, Fang Deshou. Fang Deshou is in his mid-thirties this year, and was only 29 six years ago. He does not live in the village, but opened a shop in Qinghe City after marriage." Lei Xin studied the information on the road .

Liu Jinghui nodded: "Do you know the specific address?"

"Some people have been sent over to ask questions. They have arrived at the place. I told them to start at the same time." Lei Xin is an old detective, and he is very proficient in this part.

Ahead, the village cadre wanted to knock on the door, but was stopped for a moment. Several criminal police officers ran around behind him before Lei Xin started to knock on the door.

Ordinary inquiries wouldn't be so troublesome, but with both the captain and Jiang Yuan here, everyone's details were handled very well.

The door opens.

46-year-old Fang Defu opened the door and saw groups of police officers. He frowned and said, "Didn't the police come before?"

"Fang Defu?" Lei Xin stepped forward and asked.

"Yes." Fang Defu asked, "Have you found my brother?"

Lei Xin still didn't answer, only asked: "We have a few questions to ask you about your brother's disappearance."

"Didn't I ask all of them..."

"I have a few detailed questions to ask you. What were you doing two weeks before you reported the crime?"

"Me? What do you ask me for?" Fang Defu did not answer directly, but asked a question first.

Lei Xin smiled. He had been a criminal police officer for so many years. He had an inexplicable affinity for people who asked questions or repeated them first. So he took out a cigarette, handed it to Fang Defu, and said, "Don't worry. Think slowly and have a cigarette.”

Fang Defu took the cigarette and held it skillfully between his hands, but the cigarette butt started to dangle around due to unconscious shaking.

The cigarette was shaking, and Fang Defu panicked and tried to control it, but the cigarette fell to the ground uncontrollably.

Several detectives present showed contemptuous and helpless smiles.

Liu Jinghui looked at Jiang Yuan, then turned back to a large group of criminal policemen in front of him, and sighed helplessly. The enemies of his reasoning were not only surveillance videos, but also junior criminals whose psychological quality was not up to par!
