Chapter 44 Analysis Report Released
It was rainy on the night of September 28, 3020.
In the north in late autumn, the night temperature is already less than ten degrees Celsius.
In rainy weather, the temperature dropped sharply, and the pattering autumn rain beat on the doors and windows.
In the anatomy room, Lu Chuan was facing a pile of dead bones.
The skeleton identification and analysis report is nearing completion.
Now, Lu Chuan is doing an analysis of the cause of death.
"Part of the broken sternum showed 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. place.
There are differences in the broken marks of the two ribs.
One is a crush mark, where heavy objects crush the sternum and the force on the sternum exceeds the limit, causing it to break.
But the other kind of mark is not a crushing mark, but a shattering mark caused by a violent short-term impact.
The skeleton was found under the highway foundation.
Combined with this scenario, the crushing marks, as analyzed by Li Kai, were probably caused by the rollers rolling the road.
However, there will be no signs of shattering due to impact.
Unless the deceased had been hit by a vehicle or other high-speed object before he was alive, then buried in the roadbed, and then crushed by a road roller.
In this way, two different signs of bone fracture will appear.
However, if it is a vehicle impact, the leg bones are most likely to be broken.
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 skeleton identification and analysis report can be convinced and become judicial evidence.
Four thirty in the morning.
Lu Chuan stretched, took the report from the printer, and breathed a long sigh of relief.
Open the window of the anatomy room, and the fresh air with the unique smell of rain rushes into your face.
Lu Chuan's somewhat mushy mind cleared up and his spirit was slightly lifted.
The identification and analysis of the skeleton is finally completed.
"Is it done?"
Outside the crack room, Li Kai had received the news and came hand in hand with Wang Changjiang.
Lu Chuan nodded: "The skeleton is completely preserved, and the Tianzhou City Criminal Investigation Detachment has advanced instruments, so the analysis this time is faster."
"That's 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 solidify.
"The deceased...was abused during his lifetime?"
Lu Chuan nodded solemnly: "This is basically certain, but whether it was abuse or torture, it is difficult to determine now."
"What is certain is that the deceased's sternum was struck with a hammer or other blunt instrument before he died, 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 have two different fracture marks. In addition to the crushing and shattering marks, there are also impact and shattering marks."
Lu Chuan took the report and pointed Referring to the conclusion and analysis of the reasons: "The possibility of a vehicle collision is unlikely because the leg bones of the deceased are intact, which denies the possibility of a vehicle causing death and then burying the body."
"I just had a bone fracture Experiments revealed that the cracks in the deceased’s sternum were probably caused by vigorous hammering with something like a hammer.”
"Moreover, there are six cracks with such marks on the bones. In other words, the deceased suffered at least six similar heavy blows during his lifetime."
"Generally speaking, only torture, or This situation only occurs during torture, and judging from the extent of the bone fragments, two of the six fragments were near the heart, two were in the lungs, and the rest were on the left and right lower ribs of the heart. The ribs should have been inserted into the heart, which is a fatal injury.”
The ribs were broken by hammering with blunt objects such as hammers, which were inserted into the heart, which was the cause of Lu Chuan’s death.
“One more thing,” Lu Chuan turned the report to the end: “I conducted a rough analysis of the soil cleaned from the skeleton and found that there was sand and clay on the skeleton.”
"This is abnormal, because the soil composition in a burial site should be similar, and there won't be such a big difference."
"So, I suspect that the bones have been moved or replaced. The burial site. "
"Of course, the location where the bones were found was under the foundation of the highway. It is possible to transport earth from other places for the construction of the highway. In that case, it is also possible that different types of soil would appear. "
However, Li Kai shook his head: "I know that highway. It was originally a rebuilt national highway. 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.
Earthwork, which basically uses local materials, can also form drainage ditches, killing two birds with one stone.
"Officer Lu, Lao Wang, I want to hand this report to the detachment leader immediately. I will arrange for someone to take you to rest first."
Lu Chuan and Wang Changjiang nodded.
They are only here to provide technical support, not to solve the case.
After staying up most of the night, Liu Guodong was feeling better. He just took a rest while waiting for Lu Chuan to do the appraisal and analysis.
Lu Chuan actually worked for seven or eight hours.
The high concentration, complex calculations and analysis made Lu Chuan very exhausted.
Lu Chuan and Wang Changjiang returned to the hotel arranged by the Criminal Investigation Detachment to rest. Li Kai and the others could not sleep.
Tianzhou City Criminal Investigation Detachment Case Analysis Conference Room.
The skeleton identification and analysis report has been sent to the detachment leader Wang Chuanmin.
"The deceased, male, was 1.78 meters tall and weighed 80 kilograms. He was forty years old at the time of death and was buried for sixteen years."
"There were tophi on the ankles and the tip of the tailbone was worn more than average. The deceased had high bone density and lower bone density than his peers. The deceased worked for a long time and lacked exercise, and his living conditions were relatively generous."
"There were six cracks and fractures on the ribs on the chest of the deceased. It was judged that the deceased had been abused or abused during his lifetime. Torture."
"The cause of death was determined to be that a hammer or other blunt instrument was struck on the chest, and the ribs were broken and inserted into the heart, causing death."
"Two different types of sand and clay were found in the gaps between the bones. Type of soil composition, it is suspected that there are traces of corpse removal after the skeleton was skeletal. The details should be determined based on the soil quality test at the crime scene.”
Wang Chuanmin carefully read this extremely detailed skeleton identification and analysis report.
After a moment, he looked at Li Kai in disbelief: "Is this... really the analysis report made by Xiao Lu from the Haizhou City Criminal Investigation Detachment?"
Li Kai nodded with a wry smile: "I was always present when Officer Lu Chuan was doing the skeletal analysis, and I watched the report come out with my own eyes."
"However, I couldn't understand how this report came out."
Li Kai can understand every job Lu Chuan does.
Spectral analysis measures bone carbon attenuation, and a bone density detector measures bone density...
Li Kai can be said to know every step Lu Chuan makes.
But Li Kai couldn't understand the process of combining these things together and going through complex calculations to arrive at this report.
“However, I have seen the skeleton analysis report made by senior Zhang Yuanchao before. Although Lu Chuan’s report is inferior in some details, the overall analysis results should be OK.”< br>
Although Li Kai cannot make this report, it does not mean that he cannot distinguish whether the report is true or false.
This is like those experts who appraise paintings. If you ask them to draw, they will definitely not be able to draw it.
But if you let him taste the authenticity, there is no problem.
It's like a boy or girl fighting for the first time. They don't need anyone to teach them. They can still figure out where their strengths and weaknesses are.
Wang Chuanmin was amazed, but he couldn't care less.
No matter how he made it, as long as it works!
