Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 44 Analysis Report Released
In 28, on the night of September [-], it was cloudy and rainy.

In the north in late autumn, the temperature at night is less than ten degrees Celsius.

In the rainy weather, the temperature dropped sharply, and the pattering autumn rain beat on the doors and windows.

In the dissection room, Lu Chuan was facing a pile of dead bones.

The bone identification and analysis report is nearing completion.

Now, what Lu Chuan is doing is analyzing the cause of death.

"Part of the broken sternum shows signs of collapse, which shows that the deceased suffered a major impact during his lifetime."

Lu Chuan picked up the two ribs, compared them repeatedly, and found some differences.

There are differences in the marks of the fracture of the two ribs.

One is crushing marks, where heavy objects are crushed, and the force on the sternum exceeds the limit, causing it to break.

But the other kind of marks are not crush marks, but shatter marks formed by violent short-term impact.

The bones were found under the foundation of the highway.

Combined with this scene, the traces of crushing, as analyzed by Li Kai, are likely to be caused by the road roller.

However, in any case, there will be no shatter marks from the impact.

Unless, the deceased was hit by a high-speed object such as a vehicle before he was alive, and then buried in the roadbed, and then rolled over by a road roller.

In this way, there will be two different traces of bone fracture.

However, if it is a vehicle impact, the high probability of fragmentation is the leg bone.

The reality is that the sternum of the skeleton has impact marks, but the leg bones are intact.

……

Lu Chuan did every analysis very carefully.

Any conclusion is supported by data, and only such a bone identification and analysis report can be convinced and become judicial evidence.

It was four thirty in the morning.

Stretching, Lu Chuan took the report from the printer and let out a long sigh of relief.

Pushing open the window of the dissecting room, the fresh air with the unique smell of rainwater blows in.

Lu Chuan's somewhat confused mind was cleared up, and his spirit was slightly lifted.

The identification and analysis of the bones was finally completed.

"finished?"

Outside of Jiecha, Li Kai had already received the news, and he came here hand in hand with Wang Changjiang.

Lu Chuan nodded: "The skeleton is well preserved, and the Tianzhou City Criminal Investigation Detachment has advanced instruments, so the analysis is faster this time."

"Great, Officer Lu, thank you so much!"

Li Kai took the report from Lu Chuan and opened his eyes excitedly.

However, the content of the report made Li Kai's expression gradually freeze.

"The deceased...was abused?"

Lu Chuan nodded solemnly: "This point is basically certain, but whether it is abuse or torture is not sure right now."

"It is certain that the sternum of the deceased was hit with a hammer or other blunt instrument before his death, causing the sternum to shatter."

This is Lu Chuan's final conclusion about the different cracks in the deceased's sternum.

"The ribs on the chest of the deceased showed two different fracture marks. In addition to the marks of crushing and crushing, there were also marks of impact and collapse."

Lu Chuan took the report, pointed to the conclusion and analyzed the reasons: "It is unlikely that the vehicle was hit, because the deceased's leg bones are intact, which negates the possibility of the vehicle causing death and then burying the body."

"I just did a bone cracking experiment and found that the cracks in the sternum of the deceased should have been caused by a hammer or something like that."

"Moreover, there are a total of six cracks with such marks on the skeleton, which means that the deceased suffered at least six similar blows during his lifetime."

"Generally speaking, this happens only when massacres or torture occur, and from the analysis of the degree of bone fragmentation, among the six fractures, two crack marks are near the heart, two are in the lungs, and the rest It's all on the left and right lower ribs."

"The ribs at the heart should have penetrated into the heart, which is a fatal injury."

The hammer and other blunt objects caused the broken ribs and inserted into the heart, which was the cause of death determined by Lu Chuan.

"One more thing," Lu Chuan flipped the report to the end: "I conducted a rough analysis of the soil cleaned up from the bones, and found that there were sand and clay on the bones."

"This is abnormal, because the soil composition of a burial site should be similar, and there will not be such a big difference."

"So, I suspect that the bones have been moved, or the place of burial changed."

"Of course, the place where the bones were found was under the foundation of the highway. It is possible to build the highway to transport earth from other places. In that case, it is also possible that different types of soil appeared."

However, Li Kai shook his head: "I know that expressway. It was originally rebuilt from a national road. The foundation is very stable. It is unlikely that the earthwork will be transported from other places."

Building a highway is not the same as building a building.

This kind of earthwork is basically using local materials, and it can also form drainage ditches, which kills two birds with one stone.

"Officer Lu, Lao Wang, I will hand over this report to the detachment leader immediately, and I will arrange for someone to take you to rest first."

Lu Chuan and Wang Changjiang nodded.

They are only here for technical support, not to solve crimes.

After staying up most of the night, Liu Guodong was better. He just took a rest while waiting for Lu Chuan to do the identification and analysis.

Lu Chuan actually worked for seven or eight hours.

Lu Chuan was very mentally exhausted due to his high concentration and complex calculations and analysis.

Lu Chuan and Wang Changjiang returned to the hotel arranged by the Criminal Investigation Detachment to rest, and Li Kai and the others could not sleep.

The case analysis meeting room of the Tianzhou Criminal Investigation Detachment.

The analysis report on the identification and analysis of the bones has been sent to the detachment leader Wang Chuanmin.

"The deceased, male, was 1.7 meters tall and weighed 40 kilograms. He was 16 years old when he died, and his bones were buried for [-] years."

"There are tophi in the ankles, the wear of the tip of the coccyx is higher than the average, and the bone density is lower than that of the same age. The deceased worked for a long time, lacked exercise, and lived in relatively favorable conditions."

"The chest and ribs of the deceased showed six broken and fractured marks. It is judged that the deceased was abused or tortured during his lifetime."

"The cause of death was judged to be that a blunt object such as a hammer hit the chest, and the ribs were broken and inserted into the heart, resulting in death."

"Two different types of soil components, sand and clay, were found in the crevices of the bones. It is suspected that there were traces of corpse removal after the bones of the deceased were skeletalized. The details should be determined in conjunction with the soil quality testing at the scene of the crime."

Wang Chuanmin carefully read this extremely detailed bone identification and analysis report.

After a while, he looked at Li Kai in disbelief: "This... is really the analysis report made by Xiao Lu from the Haizhou Criminal Investigation Detachment?"

Li Kai nodded with a wry smile: "When Police Officer Lu Chuan was analyzing the skeleton, I was always there, and I watched the report come out with my own eyes."

"However, I don't understand how this report came out."

Li Kai can understand every job Lu Chuan does.

Spectral analysis measures bone carbon attenuation, and bone density detector measures bone density...

Every step that Lu Chuan made, Li Kai can be said to know.

But Li Kai couldn't understand the process of combining these things together and obtaining this report after complex calculations.

"However, I have read the skeleton analysis report made by senior Zhang Yuanchao before. Although Lu Chuan's is not as good in some details, the overall analysis result should be no problem."

Although Li Kai couldn't make this report, it didn't mean he couldn't tell whether the report was true or not.

It's like those experts who appraise paintings, if you ask him to draw, he will definitely not be able to draw.

But if you let him taste the authenticity, that's no problem.

It's also like boys and girls who are fighting for the first time. They don't need to be taught. Where there are strengths and where there are loopholes, they can still find out.

Wang Chuanmin was amazed, but he couldn't care less.

It doesn't matter how he made it, as long as it works!
