Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 527 Clue Interruption
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 details."

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 corn kernel inspection results 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 whether 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 checked some information about corn on the Internet yesterday.

Don't underestimate this little corn kernel.

The ingredients of corn from each origin are different, including 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 focused on another point: "Moisture. The moisture content of corn is very small, and it has been artificially dried."

Under normal circumstances, the moisture content of corn is 20% to 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 [-]% to [-]% 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.

Therefore, 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 is to be safely stored for a long time, its moisture content must be reduced to at least 15%.

The corn kernels found in the stone statues have a moisture content of 10%, which means they 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, do you mean to start with the large corn dryers nearby?"

For drying human corpses, ordinary small drying equipment will definitely not work. However, 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 dried the corpse and formed a mummy."

"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 this corn is dehydrated to only 10% moisture content..."

"It is relatively easy to dehydrate corn from the 30% to 40% range to 15%. To reach 14%, more energy is consumed. The 13% moisture content is only available in large and high-standard grain depots. Such high demands.”

"Ten percent moisture content... is impossible to achieve in a large corn drying tower."

Lu Chuan said that this impossibility is not absolute, but impossible 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.

Therefore, from an economic point of view, it is impossible for the corn in a large drying tower to have a moisture content of 10%.

When 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 there is a high chance that some clues can be found during the investigation.

But now this clue is broken.

Lao Bai frowned: "But if it weren't for a large drying equipment, how could it be possible to dry the body to this extent?"

The oven definitely doesn't 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, there seems to be 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. There is a high probability that the murderer knew the deceased.

The reason is easy to deduce. 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, they would most likely hide the body or destroy the body 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 would be 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 clue.

Yang Sen slapped his thigh: "Okay, we are not on the front line. We have done all the work we can do. Let the operations team have a headache for the rest."

"Come on, come on, yesterday my classmate mailed me a tea set to make a pot of tea!"

With that said, he patted Lu Chuan on the shoulder and motioned to make tea with him.

Lu Chuan let out a long sigh of relief.

In fact, what Lao Yang said was right. After all, he and the others were technical criminal police officers, conducting on-site investigation. Once the on-site investigation work was completed, their own work was 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.

It takes dozens, hundreds, or even hundreds of people working together to solve a case.

The few of them are thinking nonsense here, maybe the action team has a clue already.

Lu Chuan was also accustomed to his participation in the previous cases, and he always wondered if some decisive clues could be found 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 haven't seen it before, it's a new thing! Come and try it!"
