Chapter 527 Clues Interrupted
In the car, Zhang Hui began to arrange the next work of the action team.
"First, Zhao Shengli cannot let down his guard. Check his interpersonal relationships to see who he has major conflicts of interest with, and pay attention to the male missing persons among them."
" Second, find the mason’s hometown and check the specific situation.”
While the action team was working in the Stone Carving Garden, there was also new progress in the current survey office.
The test results of the corn were finally sent back.
In the laboratory, four people gathered around a report.
“Haizhou City?”
Yang Sen frowned and spoke in confusion.
The inspection results of the corn kernels from the seed industry company showed that the corn in the stone statue was produced around Haizhou City.
"Whether the corn kernels were brought in by the deceased, or the murderer accidentally brought them into the stone statue, it means that the place where the crime occurred, the deceased, and the murderer may be people from around Haizhou City?"
Lao Bai Yesterday I checked some information about corn on the Internet.
Don’t underestimate this little corn kernel.
The ingredients of corn in each origin include different starch content, protein content, and moisture content.
Especially the trace element content can more accurately determine the origin of corn.
The conclusion given by the seed industry company is that corn is produced around Haizhou City because corn contains a relatively high amount of zinc trace elements, and the proportions of various trace elements are relatively close to those in the soil around Haizhou City.
Lu Chuan is concerned about another point: "Moisture, the moisture content of corn is very small, and it is artificially dried."
Under normal circumstances, the moisture content of corn is 20%~ 30%.
But during the actual harvesting process, Lu Chuan specifically asked his classmates who had lived in rural areas yesterday.
The moisture content of harvested corn is generally between 30% and 40%. In farmers' terms, it contains thirty to forty percent water.
Corn with this kind of moisture content is prone to mildew and is not suitable for long-term storage.
In the north, corn is easier to store only after a long period of freezing in winter.
So the selling price of corn is related to its moisture content. If the moisture content is low, the selling price will be high. If the moisture content is high, the selling price will be low.
If corn wants to achieve long-term safe storage, its moisture content must be reduced to at least 15%.
The moisture content of the corn kernels found in the stone statue is 10%, which means it must have been artificially dried.
Under natural conditions, it is difficult for corn to reach this moisture content.
Yang Sen discussed this issue with Lu Chuan yesterday: "Xiao Lu, you mean to start with the large corn dryers nearby?"
Drying human corpses, generally Small drying equipment will definitely not work, but if it is a large corn dryer or drying tower, it would be better to achieve this effect.
But Lu Chuan shook his head.
“Before seeing the test report of corn kernels, I think it is very possible that a corn dryer or drying tower would dry the corpse and form a mummy.”
< br>
"But..." Lu Chuan picked up the test report: "I checked the information yesterday and asked some classmates who are still farming in rural areas. Regarding corn drying, the water level in the drying tower only needs to reach 14 15 water is the standard for safe storage.”
“But corn like this is dehydrated to only 10% moisture content...”
“The moisture content of corn is from 30%. It is relatively easy to dehydrate from 40% to 15%. To reach 14%, more energy is consumed. Only large and high-standard grain depots have such high requirements for the 13% moisture content. ”
"10% moisture content... is impossible to achieve in a large corn drying tower."
Lu Chuan said that this impossibility is not absolute, but relative.
The drying tower can indeed reduce the moisture content of corn to 10%, but it consumes a lot of energy and is not necessary. At the same time, the lower the moisture content, the harder it is to control the drying process.
So from an economic point of view, it is impossible for the corn in the large drying tower to reach the 10% moisture content.
After Lu Chuan explained this, Liu Guodong and the others immediately understood what Lu Chuan meant.
"You mean... excluding large drying equipment?" Lu Chuan nodded helplessly.
He checked online yesterday. Although there are many grain depots and drying equipment around Haizhou City, they are still limited.
If it can be determined that the body came out of this large drying equipment, then it is very likely to find some clues during the investigation.
But now this clue is broken.
Lao Bai frowned: "But if it wasn't a large drying equipment, how could it be possible to dry the body to this extent?"
The oven must not work.
You want to say that the body was decomposed, cut into pieces and dried, and using an oven is fine.
But the body in the stone statue is whole.
This time, it seems that there is really not much work that can be done here.
DNA information identification and fingerprint testing of the corpse were also done, but the identity of the deceased was not determined.
If the identity of the deceased is not determined, there is no way to find the murderer by investigating the interpersonal relationships of the deceased.
The murderer was able to hide the body of the deceased in the stone statue, which most likely means that the murderer did not commit the crime out of passion.
In other words, it is unlikely that the deceased was killed for no reason. The murderer most likely knew the deceased.
The reason is easy to infer. The murderer’s behavior of hiding the body exposed this.
In the vast majority of homicide cases, as long as the murderer and the deceased knew each other, there is a high probability that the body will be hidden or the body will be destroyed to eliminate traces.
The purpose is to hide the interpersonal relationship between the murderer and the deceased.
The vast majority of passionate killings basically do not involve hiding the body.
Because the murderer and the deceased did not know each other, the murderer determined that it was impossible to find him through the interpersonal relationship investigation of the deceased.
Even in this case, the murderer was very willing for the police to follow the deceased's interpersonal relationship to track down the murderer.
After thinking for a long time, they still had no idea.
Yang Sen slapped his thigh: "Okay, we are not on the front line. All the work we can do has been done. Let the action team have a headache for the rest."
"Come on, come on, my classmate mailed me a tea set yesterday, let me make a pot of tea!"
As he said that, he patted Lu Chuan on the shoulder and motioned to follow him to make tea.
Lu Chuan breathed a long sigh of relief.
In fact, what Lao Yang said is right. After all, he and the others are technical criminal police officers, conducting on-site investigation. Once the on-site investigation is completed, their own work is actually completed.
Whether a case can be solved cannot be accomplished by one or two people or one or two groups.
Action team, forensics, field investigation, logistics, and even other police types are involved.
Dozens, hundreds, or even hundreds of people can solve a case by cooperating with each other.
A few of me are just thinking here. Maybe the action team has clues already.
Lu Chuan was also used to it by his participation in the previous cases, and he always wondered whether he could find some decisive clues during the current investigation.
This time it seems that it is enough.
"Stone tea set?"
Opening the package, Lu Chuan was slightly surprised. The new tea set that Lao Yang mentioned was actually a very exquisite stone tea set.
“You’ve never seen it before, it’s something new! Come and try it!”
