In the Criminal Investigation Team, everyone takes rigor and responsibility extremely seriously.
If Lu Chuan expresses that he can conduct the skeleton analysis, it's not just about whether Wang Changjiang agrees or not.
Even if he agrees, Lu Chuan cannot guarantee that his report will pass the review from above.
After all, Lu Chuan has only received a system reward and can make an analysis report, but he does not have the ability to influence the judgment of the provincial experts.
There are no absolutes in anything, if any mistake occurs, the responsibility won't just fall on Lu Chuan.
Wang Changjiang, as the person in charge of this aspect, is the primary responsible party.
Compared to taking risks, Lu Chuan prefers to be safe.
When working, one should not be too aggressive, otherwise it will be short-lived.
"Forensic Doctor Wang, how about this? When I was in university, I studied skeleton identification analysis and have some insights in this area."
"You can first submit the request for testing analysis to the provincial department, and I'll borrow the forensic lab's equipment to practice a bit."
"Of course, you don't have to worry about the report, I'll submit it through the crime scene investigation route, it definitely won't affect us."
Wang Changjiang was very satisfied with this proposal.
Being able to submit the test through normal channels would complete the task, which would not impact the case.
As for Lu Chuan wanting to use the equipment...
Not only can he use it, he could take over the entire crime scene investigation office if needed.
Not to mention, cases involving bone detection are already rare, and even if used frequently, it still requires approval from above.
If they don't recognize your analysis, you wouldn't dare to use it even if you did it.
Not to mention, the judiciary wouldn't adopt it without the top-level approval, and Wang Changjiang himself wouldn't hand over the tests Lu Chuan did to Qin Yong for case work.
It's not like feeding a child where it doesn't matter if you use the left or right side.
This requires accountability.
As long as Lu Chuan doesn't actually break the equipment, since sometimes even colleagues come by to measure bone density and such.
There are two sides to every story.
While Lu Chuan was busy on this side, the inquiry on the other side was nearing its end.
"Where could there be so many big bones for broth? It's all flavor essence mixed in."
The staff in the hot pot restaurant kitchen didn't hide anything and answered every question.
"A spoon of Sanhua evaporated milk, and plain water can be turned into a rich broth, just throw in a few bones with no meat, and that's the base for the broth."
"The bones were sourced by our boss, there's a specific seller for these."
"But I don't know exactly where they came from, you have to ask the boss."
"Officer, did something happen?"
"It has nothing to do with me, I'm just responsible for blending the soup, adding big bones, every hot pot restaurant I worked at did it this way..."
After the inquiry ended, every detective involved probably never wanted to eat hot pot again in their life.
"Captain Qin, the hot pot restaurant owner has spilled it."
Ren Qiang personally questioned the hot pot restaurant owner: "The big bones used in the hot pot restaurant are from a feed factory."
"A feed factory?"
Qin Yong's expression was a bit surprised, clearly having a hard time believing that these big bones came from a feed factory.
Ren Qiang nodded helplessly: "They're indeed from a feed factory. This factory mainly produces pig feed, as they add bone meal, they normally purchase big bones."
"Do their big bones get supplied to hot pot restaurants as well?"
Ren Qiang shook his head: "That's not the case, regular hot pot restaurants have specific channels to purchase big bones."
"This hot pot restaurant owner knows someone at the factory, ten yuan a sack, while big bones through official channels cost nearly a hundred yuan a sack."
Qin Yong was a bit speechless, ten yuan, a hundred yuan...
Just last week he took his kids to a hot pot restaurant.
"Immediately seal off this feed factory, confiscate all materials, and detain all relevant personnel!"
The human bone fragments found in the hot pot restaurant amounted to only eighty pieces.
And each one has been cut, in terms of weight, it was less than one-twentieth the weight of a complete adult skeleton.
So where the remaining bones are is obvious.
However, the silver lining is that the channel through which the hot pot restaurant purchased bones was relatively unique.
If it were a specialized channel for selling big bones to hot pot restaurants, Qin Yong would be terrified at the thought.
Forensic Laboratory.
Lu Chuan was already beginning to prepare some preliminary work for the experiment.
Selecting experimental materials, pretreatment, bone surface observation.
Skeleton identification analysis differs from fingerprint or footprint analysis.
It requires a higher degree of experience as well as instrument measurement.
For example, bone density measurements can determine the health condition and roughly the age range of the owner.
However, the data obtained through instruments is not precise and requires manual intervention to analyze.
For example, deducing the deceased's age at death.
The instrument's calculation of bone age is actually an analysis of its elemental cycle.
However, a bone age of fifty years does not mean its owner died fifty years ago.
The person may have died at forty, but the bone was discovered ten years later.
Lu Chuan is now working on deducing the deceased's age at death by observing the "growth rings" of the bones.
Trees have growth rings, and so do bones.
As a person grows up, the bones grow in circles, and then at a certain age, they stop growing.
But this does not mean the bone's "growth rings" disappear.
The color, surface attachments, and bone spurs of adult skeletons continue to change with age.
Skeleton identification is about completing the analysis through these details.
Two hours later.
The results of the identification analysis made Lu Chuan furrow his brows.
His initial hypothesis was correct, these bones belonged to one person.
Although he hasn't received the DNA test results from Liu Guodong's side, from a skeleton analysis perspective, the color depth, age, density, and texture development of these bones are very similar.
It can be confirmed that they all belong to one person.
In addition, what surprised Lu Chuan was the time of death of the deceased.
"Sacral feature analysis: Female."
"Bone ring observation analysis: The age at death was 34 years old."
"Bone age carbon analysis: Bone age is 34 years."
"Tibia length analysis: The deceased's height was 1.63 meters."
"Bone density combined with height analysis: The deceased weighed 67 kilograms, the bone density was three percentage points higher than the average for females of similar age, height, and weight, combined with age analysis, indicating the deceased engaged in long-term manual labor."
With each analysis result, Lu Chuan attached analysis data, bone photos, and the analysis process.
The skeleton analysis report was finally completed.
But this was not the final result; Lu Chuan sent it directly through the professional technical support application channel in the office system to the technical support personnel at the provincial department.
After finishing this, Lu Chuan greeted Wang Changjiang and Shen Yan and returned to the crime scene investigation office.
He was borrowed by Wang Changjiang to help piece together the bones.
Doing skeleton analysis was actually going above and beyond the task.
Wang Changjiang didn't actually take Lu Chuan's skeleton analysis seriously.
Lu Chuan just graduated, having some curiosity is good.
As for making something of it...
Heh, what Wang Changjiang has played with all his life without understanding, can you, a college student, figure it out?
However, no one expected that Lu Chuan's report caused an uproar at the provincial department!
