Chapter 32 Bone Identification and Analysis
Working in the Criminal Investigation Detachment, everyone attaches great importance to rigor and responsibility.
If Lu Chuan said that he could do the bone analysis, let alone whether Wang Changjiang agreed or not.
Even if he agreed, Lu Chuan could not guarantee that his report would pass the above review.
After all, Lu Chuan only received a reward from the system and could make an analysis report, but he was not able to influence the judgment of experts in the provincial department.
There are no absolutes in everything, and if there is a mistake, it is not only Lu Chuan who is responsible.
Wang Changjiang, as the person in charge of this aspect, is the primary person responsible.
Compared with adventure, Lu Chuan still likes to be safe.
After all, if it weren't for the fact that he was a little aggressive during the battle in the previous life and didn't pay attention to the bunkers around him, Lu Chuan might not have been hit by a stray bullet and received a box lunch.
"Forensic Doctor Wang, do you think this will work, when I was in college, I studied bone identification and analysis, and I still have a little experience in this area."
"You will first submit the testing and analysis needs to the provincial department, and I will borrow the equipment of the forensic office to practice and learn."
"Of course, you don't have to worry about the report, I will definitely not assess us if I submit the report through the current investigation channel."
Wang Changjiang was very satisfied with this kind of proposal.
Being able to submit a test in the normal way will complete the task, which will have little impact on the case.
As for Lu Chuan's desire to use the equipment......
Don't say it, just take it to the on-site survey office.
Let's not mention that there are few cases related to bone testing, even if they are used often, they must be recognized by the above.
People don't approve of your analysis, and you don't dare to use it if you do.
Not to mention that the judiciary will not use it, without the approval of his superiors, Wang Changjiang himself will not hand over the test he did to Qin Yong to handle the case.
It's not like a child breastfeeding, the left side is fine, and the right side is fine.
This is responsible.
Lu Chuan just needs not to really break the instrument, after all, there are usually colleagues who come to measure bone density or something.
The flowers bloom with one branch at each end.
While Lu Chuan was busy here, the inquiry over there was also nearing the end.
"How can there be so many big bones in soup, all of which are made of flavor."
The kitchen staff of the hot pot restaurant did not hide it at all, and asked what to say.
"A spoonful of Sanhua evaporated milk, white water can be made into stock, and a few meatless bones are put inside, which is the bottom of the soup pot."
"The bones were bought by our boss, and there are people who specialize in selling this thing."
"But I don't know where it came from, you have to ask the boss."
"Comrade policeman, is something wrong?"
"It has nothing to do with me, I'm in charge of mixing soup and enlarging bones, and several hot pot restaurants I've worked at have done this......"
After the questioning, all the criminal policemen who participated in the questioning estimated that they would never want to eat hot pot in their lives.
"Team Qin, the owner of the hot pot restaurant has picked it up."
Ren Qiang personally asked the owner of the hot pot restaurant: "The big bones used in the hot pot restaurant come from a feed factory. ”
"Feed mill?"
Qin Yong's eyes were a little surprised, obviously a little incredulous that these big bones came from the feed factory.
Ren Qiang nodded helplessly: "It is indeed from a feed factory, this factory mainly produces pig feed, because bone meal is added to it, and all the big bones are usually purchased." ”
"Their big bones will also be supplied to hot pot restaurants?"
Ren Qiang shook his head: "It's not, general hot pot restaurants have specific channels for buying big bones." ”
"The owner of this hot pot restaurant knows the people in the factory, and he costs ten yuan a sack, and the big bones of a specific channel cost nearly 100 yuan a bag."
Qin Yong was a little stunned for a while, ten yuan, one hundred yuan......
He only took his children to eat hot pot last week.
"Immediately shut down this feed mill, all materials were sealed, and all relevant personnel were controlled!"
The human bones and bones found in the hot pot restaurant were only eighty in total.
And each piece has been cut, less than one-twentieth of the weight of an adult's whole body bone in terms of weight.
So, where the rest of the bones are, it's obvious.
However, fortunately in the misfortune, the channel for buying bones in hot pot restaurants is relatively special.
If it was a channel dedicated to selling big bones to hot pot restaurants, Qin Yong's scalp would be numb when he thought about it.
Forensic laboratories.
Lu Chuan has already started to make some preparations before the experiment.
Experimental materials were selected, preprocessed, and bone surface was observed.
The identification and analysis of bones is different from the analysis of fingerprints and footprints.
While the need for experience is higher, it is also necessary to measure with the help of instruments.
For example, bone density, bone densitometry can determine the health of the owner, the approximate age range.
However, the data obtained with the help of instruments is not accurate and requires human intervention and analysis.
For example, the age of the deceased is inferred.
The measurement of bone age by the instrument actually analyzes its elemental period.
But if the bone age of a bone is fifty years, it cannot be said that the time of death of its owner is fifty years.
He may have died at the age of forty, but the bones were found ten years later.
What Lu Chuan is doing now is to calculate the age of the deceased at the time of death by observing the "growth rings" of the bones.
Trees have growth rings, and bones also have "growth rings".
People grow from small to large, and the bones grow from small to round and round, and then at a certain age, they stop growing.
But that doesn't mean the "rings" of bones are gone.
Adult bone color, surface attachments, and bone hyperplasia continue to change with age.
The identification of bones is based on these details to complete the analysis.
Two hours later.
The results of the appraisal analysis made Lu Chuan frown.
His initial reasoning was good, the bones belonged to a person.
Although he still doesn't know the DNA information test results from Liu Guodong's side, from the perspective of bone analysis, the color depth, age, density and texture development of these bones are extremely similar.
It can be determined that it is owned by one person.
In addition to this, what surprised Lu Chuan was the time of the deceased's death.
"Sacral Characterization Analysis, Female."
"According to the observation and analysis of the bone wheel, the deceased was 34 years old at the time of death."
"Bone age carbon detection and analysis, bone age time is 34 years."
"Tibia length analysis: the deceased is one meter six three tall."
"Bone density combined with height analysis: the deceased weighed 67 kilograms, bone density was three percentage points higher than the average of women of similar height and weight of the same age, combined with age analysis, the deceased had been engaged in manual labor for a long time."
After each analysis result, Lu Chuan paid for the analysis data, bone photos, and the analysis process.
The skeletal analysis report is finally complete.
But this is not the final result, Lu Chuan directly sent it to the technical support personnel of the provincial department through the professional technical support application channel in the office system.
After finishing it, 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 put together the bones.
Engaging in skeleton analysis is actually overfulfilling.
Wang Changjiang actually didn't take Lu Chuan's bone analysis seriously.
Lu Chuan has just graduated, and it's good to be a little curious.
As for making a roll call......
Hehe, he Wang Changjiang has never understood anything in his life, and you can do it as a college student?
However, no one expected that Lu Chuan's report would cause an uproar in the provincial department!
