Chapter 557: Hard Bone

"Roughly estimate, the corpse has been there for three years, buried relatively shallow, but the position is okay, wrapped in a straw mat. Should this count as burial?"

Niu forensic doctor is also very confident in making on-site judgments.

A technician who can study a piece of toilet paper to the LV3 level, his main job is not bad, at least there is an LV2 level. Facing a corpse without special decoration, it is no problem to give an approximate year.

Jiang Yuan also nodded and said: "It happened to be the time before and after Zhang Enfan returned to the country, but it is not very certain. Check the straw mat later."

The lower body of the corpse has not completely rotted away, so you can see some muscles on the back sticking to the straw mat.

As for the specific time of death, you have to go back to see the situation of the insects caught, or carefully examine the situation of the bones, or see what is in the corpse water, or you can judge by the plants inside and outside the grave.

But in any case, for a corpse that has been skeletonized for three years, wanting a relatively accurate time judgment is not an easy thing. Jiang Yuan's LV6 time of death identification also needs time to identify.

However, adopting the burial method shows that the first scene of death is not here, and...

"This doesn't fit the relationship between gamblers and gambling houses." Wang Lan said this conclusion, and Jiang Yuan and Niu Tong nodded in agreement.

If it is a gambling house murder, they are more likely to let the victim dig the pit himself, dig it almost, stab to death, etc.

In this case, the victim often has traces of being beaten or abused—without giving a little power, naturally, he will not obey, and honestly dig a pit for himself.

In addition, this method also relies on the gambling house's sufficient manpower.

If it is a single-handed murder, the work of digging the pit may have to be done by himself, but in any case, wrapping a straw mat or something is impossible.

Even under forced circumstances, living people will not be quietly wrapped in straw mats.

And the killer has no human feelings.

"The source of the corpse is not very easy to determine." Niu Tong squatted down again and began to pick up bones seriously.

Also coming was a forensic assistant from the Qinghe Municipal Bureau, who worked silently.

"Go back and see if you can find someone. At least the skull is still there." Jiang Yuan paused, and said to Wang Chuanxing next to him: "Zhang Enfan's interpersonal relationship still needs to be checked, and see if there are any missing people in the Zhang family."

The workload of skull restoration is not low, similar to forensic botany. Before the mountains and rivers are exhausted, Jiang Yuan doesn't want to start it. It's like the computer blue-screened. The first choice is to restart the computer, not to reinstall the operating system.

In contrast, forensic anthropology is more humane.

Three forensic doctors worked together to load the corpse, straw mat, and various insects into the car and returned to the Qinghe Municipal Bureau's forensic autopsy room.

Niu forensic doctor picked up a few large pots and boiled the bones that had not completely rotted away.

The boiled bones have a matte white color. Looking at the bones in general, they are very slender. Looking at the bones alone, it is actually difficult to imagine that such a skeleton can support a body of two hundred jin, three hundred jin.

The pelvis of the corpse is still there, so there are many things that can be judged. Gender, age, height, time of death, etc., can all be judged based on this.

Of course, when all the bones are there, you can use the pelvis as the main and other bones as auxiliary.

Jiang Yuan didn't be humble either. While the heat of the bones was still there, he measured the length and width ratio of each part of the bones, that is: "Female, young 21 years old, height 165 to 167, time of death... three years and two months... more specifically... I'll check the almanac."

Jiang Yuan said, took off his gloves, and turned to find the tablet computer.

Wang Lan and Niu Tong were originally listening in a learning manner, and when they heard the end, they suddenly raised their heads and looked at each other.

Niu Tong asked in a low voice: "What trick did you learn from Wu Jun?"

Wang Lan shook his head blankly, didn't hear any wind, but the word "almanac" was still a bit out of the scene.

"1160 days, about a week before and after." Jiang Yuan searched the almanac and came back.

Wang Lan asked: "Time of death? What does it have to do with the almanac?"

"Oh, because plants can be used as auxiliary references. For example, the plants on the grave bag were definitely cut off before, and there are also cut plant roots in the grave. I just checked the almanac to determine the growth rate." Jiang Yuan explained this, and Wang Lan and Niu Tong understood.

Digging a pit in the forest in the wild, the plants at the original position must have been dug off. After three years, some old roots may have been eaten by insects, but some strong ones have remained.

On the other hand, the newly grown plants also have solar terms. Some plants can grow at any time, and some plants have to wait until a certain solar term to start growing, typically like bamboo, which will emerge from the soil after the Qingming Festival.

There are more than 30 kinds of plants scanned at the scene, including some familiar or rare weeds. Wang Lan and others know a little about the principles of forensic botany, but when it comes to specific applications, they are two eyes and one wipe.

Listening to Jiang Yuan's explanation, Wang Lan and Niu Tong were considered to have defaulted. Anyway, they didn't understand, so they counted according to what Jiang Yuan said.

And for cases of death three years ago, it is almost enough to judge a year. In special cases, it can be accurate to within a month, which is very powerful and special.

Jiang Yuan's wave is equivalent to being accurate within a half-month time interval. As for whether it is necessary, it depends on the development of the case. In terms of technical support, it is considered full.

Three forensic doctors didn't follow the case directly, so they threw the results to Wu Junhao.

The Baldy Squad led by Wu Junhao was once the heavy case squadron of the Ningtai County Criminal Police Brigade, and was a temporary rival with Liu Wenkai's Second Squadron.

Homicide cases and the like, Wu Junhao also did often before, it is just that this kind of old case is not easy to do.

However, Wu Junhao's personality is brave and rushing, and although his subordinates are only the young Baldy Squad, he is not timid at all.

When young people organize interpersonal relationships, there are omissions, then help organize, help check for omissions. Those with bad habits, those who write inquiry records roughly, then take them over and teach them to write again. Those who are lazy, love to steal and slip, Wu Junhao accompanies them to do it together.

From the moment he took the case, Wu Junhao threw himself into the case.

In just three days, he bought more than a hundred meat sandwiches.

The young Baldy Squad members ate the meat sandwiches bought by Wu Junhao, and could only investigate the case day and night. They had to run two kilometers in the morning, and had to play with dumbbells when they were free.

Saturday.

Case analysis meeting.

Huang Qiangmin also rushed over to participate.

Compared with technical personnel such as Jiang Yuan, Wu Junhao's expression was more solemn.

This case is still left in the Litang Township Police Station, and he presided over the participation, which was caused by Jiang Yuan's influence.

But Wu Junhao also knows that if there is no progress, Huang Qiangmin will definitely let the criminal police brigade intervene.

This is not just Chai Tong staring at it, the homicide case itself is not allowed to be missed.

The corpse Jiang Yuan dug up this time is equivalent to a newly issued homicide case. The best time to solve the case was more than three years ago, followed by now.

Huang Qiangmin will not tolerate Wu Junhao wasting time. Those petty theft cases in the police station, or sticky public security cases, Huang Qiangmin's attention is very low, but homicide cases are impossible to relax.

That is to say, it happened in Litang Township, the local police have advantages, and Jiang Yuan is by his side, so Huang Qiangmin gave Wu Junhao a chance.

Everyone is seated.

Wu Junhao organized slightly and said: "In terms of interpersonal relationships, Zhang Enfan's relatives don't know what he has done in recent years. The Zhang family itself has no missing population. It means a headless case."

"However, Zhang Enfan's subordinates have talked about some rumors."

"It is said that Zhang Enfan said when he was drunk that when he was abroad, he had been betrayed by his girlfriend, and he also decisively disposed of it. Decisive killing, this is Zhang Enfan's original words."

"We don't know much about the situation abroad, but from the time point of view, Zhang Enfan should have been in the country at that time."

"In addition, the burial site is the Zhang family's ancestral grave. There is only one road in and out locally, which is very remote. Outsiders are unlikely to know this place."

"Combining the above points, we believe that Zhang Enfan still has a major suspicion of committing a crime."

Huang Qiangmin waited for Wu Junhao to finish, knocked on the table, and asked: "What about evidence? How is the interrogation of Zhang Enfan?"

"It's a hard bone, and has been keeping silent." A police officer next to him said.

Huang Qiangmin immediately looked at Jiang Yuan.

"The killer's killing method is strangulation, the strength is very large, the victim's hyoid bone is fractured... Checked the corpse's fingernails and other places, didn't find residual DNA, it is possible that it was cleaned and processed..."

Jiang Yuan said this, paused, and said: "I started skull restoration yesterday, and it should be completed in a few days. By then, the source of the corpse can be determined."

Following this remark, Huang Qiangmin's mood inexplicably relaxed, and the corners of his mouth couldn't help but curl into a 33.3-degree smile.

Of course, his mood should also be relaxed. Skull restoration + forensic botany + forensic anthropology, with LV6 time of death identification, and there is no shortage of LV4 crime scene investigation in the middle. This set of technology used for psychological massage is definitely top-notch. ===== CHAPTER 558 =====
