Chapter 32 Skeleton Identification Analysis
Working in the criminal investigation detachment, everyone attaches great importance to rigor and responsibility.
If Lu Chuan said that he could analyze the skeleton, let’s not say whether Wang Changjiang agreed or not.
Even if he agrees, Lu Chuan cannot guarantee that his report will pass the review above.
After all, Lu Chuan only received system rewards and could make analysis reports, but he had no ability to influence the judgment of provincial experts.
There are no absolutes in everything, and if something goes wrong, it's not just Lu Chuan who will bear the responsibility.
As the person in charge of this aspect, Wang Changjiang is the primary person responsible.
Compared with taking risks, Lu Chuan still prefers playing it safe.
The director cannot be too radical, otherwise the time will be short.
"Forensic Doctor Wang, do you think this will work? When I was in college, I learned about skeletal identification and analysis, and I have some experience in this area."
"You first report your testing and analysis needs to the provincial department. I will borrow the equipment of the forensic room to practice and learn."
"Of course, you don't have to worry about the report. I will submit the report through on-site investigation. We will definitely not be tested.”
Wang Changjiang was very satisfied with this formulation.
If you can submit the test in the normal way, you can complete the task and it will have no impact on the case.
As for Lu Chuan wanting to use the equipment...
Forget about using it, you can just take it to the current survey office.
Not to mention that there are very few cases related to bone testing. Even if it is used frequently, it still needs approval from the higher authorities.
If people don’t approve of your analysis, you won’t dare to use it even if you do it.
Not to mention that the judiciary will not adopt it. Without the approval of his superiors, Wang Changjiang himself would not hand over the test he did to Qin Yong for handling the case.
This is not like a child sucking milk. It can be done on the left side or on the right side.
It's about being responsible.
As long as Lu Chuan doesn't really damage the instrument, it will be fine. After all, colleagues usually come over to measure bone density or something.
The flowers bloom, one at each end.
While Lu Chuan was busy here, the inquiry over there was coming to an end.
“How can there be so many big bones to make soup? They are all made from essence.”
The kitchen staff at the hot pot restaurant didn't hide anything, and they said whatever they asked.
“A spoonful of Sanhua evaporated milk and plain water can be used to make the stock. Put a few meatless bones in there and that will be the bottom of the stock pot.”
“Bones are our boss. There are people who specialize in selling this stuff.”
“But I don’t know where it comes from. You have to ask the boss.”
“Comrade police, is something wrong? ?”
"It has nothing to do with me. I am responsible for mixing the soup and enlarging the bones. Several hot pot restaurants I have worked at have done this..."
After the interrogation, all the criminal police officers involved in the interrogation estimated that this I never want to eat hot pot again in my life.
"Captain Qin, the hot pot restaurant owner has given up."
The hot pot restaurant owner who Ren Qiang personally asked: "The big bones used in the hot pot restaurant come from a feed factory."
< br>"Feed mill?"
Qin Yong's eyes were a little surprised, and he obviously couldn't believe that these big bones came from a feed factory.
Ren Qiang nodded helplessly: "It does come from a feed factory. This factory mainly produces pig feed, because bone meal is added to it, so it usually purchases large bones."
" Their big bones will also be supplied to hot pot restaurants?"
Ren Qiang shook his head: "That's not true. Most hot pot restaurants have specific channels for purchasing big bones."
"That's right. The owner of the hot pot restaurant knows the people in the factory, and the price is ten yuan a bag, while the big bones from certain channels cost nearly a hundred yuan a bag.”
Qin Yong was a little stunned for a moment, ten yuan, a hundred yuan...
He only had hot pot with his children last week.
“Stop this feed factory immediately, seal all materials, and put all relevant personnel under control!”
A total of only eighty pieces of human bones were found in the hot pot restaurant. .
And each piece has been cut. In terms of weight, it is less than one-twentieth of the weight of an adult's whole body bones.
So, it's obvious where the remaining bones are. However, luckily among misfortunes, hot pot restaurants have a special way to purchase bones.
If it were a channel specifically for hot pot restaurants to sell big bones, Qin Yong's scalp would go numb just thinking about it.
Forensic Laboratory.
Lu Chuan has already begun to make some preparations before the experiment.
Select experimental materials, preprocess, and observe bone surfaces.
Skeletal identification analysis is different from fingerprint and footprint analysis.
While the demand for experience is higher, it is also necessary to use instruments for measurement.
For example, bone density. Bone density measurement can determine the owner's health and approximate age range.
However, the data obtained with the help of instruments is not accurate and requires human intervention for analysis.
Such as inferring the age of the deceased.
The instrument's calculation of bone age actually analyzes its elemental period.
But if the age of a bone is fifty years, it cannot be said that the time when its owner died was fifty years.
He may have died at the age of forty, but the bones were discovered ten years later.
What Lu Chuan is doing now is to estimate the age of the deceased at the time of death by observing the "growth rings" of the bones.
Trees have annual rings, and bones also have “annual rings.”
When a person grows up, his bones grow in circles, and then stop growing when he reaches a certain age.
But this does not mean that the "annual rings" of the bones have disappeared.
The color, surface attachments, and bone growth of adult bones will continue to change with age.
Skeletal identification is to complete the analysis through these details.
Two hours later.
The results of the identification analysis made Lu Chuan frown.
His initial inference was good, these bones belonged to one person.
Although he does not yet know the DNA information test results from Liu Guodong, from the perspective of skeletal analysis, the color depth, age, density and texture development of these bone fragments are all very similar.
It is certain that it is owned by one person.
In addition, what surprised Lu Chuan was the time of death.
"Sacrum characteristic analysis, female."
"Bone wheel observation analysis, the deceased was 34 years old at the time of death."
"Bone age carbon detection analysis, bone age time 34 years."
"Tibial length analysis: The deceased was 1.63 meters tall."
"Analysis of bone density combined with height: the deceased weighed 67 kilograms, and the bone density was three percentage points higher than the average level of women of similar height and weight of the same age. Combined with age analysis, the deceased had been engaged in physical labor for a long time."
After each analysis result , Lu Chuan paid for the analysis data, bone fragment photos and analysis process.
The skeleton analysis report is finally completed.
But this was not the final result. Lu Chuan sent it directly to the technical support staff at the provincial department through the professional technical support application channel in the office system.
After finishing, Lu Chuan said hello to Wang Changjiang and Shen Yan and returned to the field survey office.
He was borrowed by Wang Changjiang to help piece together the bones.
The analysis of the skeleton has actually overfulfilled the task.
Wang Changjiang actually didn’t take Lu Chuan’s skeletal analysis seriously.
Lu Chuan has just graduated, so it’s good to be a little curious.
As for making something famous...
Haha, Wang Changjiang can do something that he, Wang Changjiang, has never understood in his whole life, just a college student?
However, no one expected that Lu Chuan’s report would cause an uproar in the provincial department!
