Chapter 524 Case Analysis Meeting
The stone statue containing the corpse is hollow inside. The two parts are bonded with strong glue, and the gaps between the bonds are polished, so it looks like the entire statue on the outside.
Lu Chuan is currently collecting the materials inside the stone statue.
It shows that it was scanned through ultraviolet light, but unfortunately, no clues such as palm prints or fingerprints were found.
Or maybe there were palm prints or fingerprints left, but they have long since disappeared after such a long time.
Fingerprints or palm prints are very easy to erase on-site traces.
Compared with footprints, fingerprints are caused by human fingers secreting oil and sweat. These trace amounts of substances remain on the surface of objects through the fingerprint path, forming fingerprints.
However, this kind of pattern can only remain for a short time. The longer the oil and sweat evaporate, the fingerprints will naturally disappear.
Under normal circumstances, the time for fingerprints to remain outdoors is relatively short. Due to sunlight exposure and air flow, the sweat and oil on the fingerprints will generally evaporate completely in less than half a month, making them impossible to detect and impossible to collect. .
However, fingerprints left indoors are stored for a relatively long time.
Without external interference, fingerprints left indoors can generally last for about half a year.
Of course this is the ideal maximum time.
The inside of the stone statue is similar to this ideal state, with no air flow and no external interference factors. If the murderer leaves fingerprints, they may be retained for a longer period of time.
But unfortunately, there are no fingerprints left inside the stone statue, but it is not without any findings.
“Is this... corn kernel?”
Lu Chuan found a corn kernel at the bottom of the stone statue.
Yang Sen collected the corn kernels and put them into the evidence bag.
“Why is there such a thing in this stone statue?”
Lu Chuan frowned and was a little confused about this: “Take it back and test it first. It is impossible for corn kernels to appear in the stone statue out of thin air. There is a high probability that the corpse was brought in. "
"In addition, based on the analysis of this corn, it is very possible to obtain information about its origin, which may be helpful to the case. "
The protein content and moisture content of seeds formed by crops of the same variety in different origins are different.
Especially the protein content, species produced in different origins vary greatly, and have relatively strong regional characteristics.
But Lu Chuan only has some understanding and doesn’t know much about these aspects. He may need technical support from the seed industry department.
The on-site survey work will not end until after 9pm.
Because the stone statue is too bulky, there is no way to transport it back to the Criminal Investigation Detachment.
Moreover, Lu Chuan had already completed the relevant on-site investigation, so there was no need to transport the stone statue back.
Wang Changjiang, Shen Yan and others took the first step and have already transported the body back for autopsy.
When Lu Chuan and others returned to the detachment, it was already 11:30 pm.
"Notify all departments to hold a meeting first and talk about it."
Qin Yong immediately held a case analysis meeting.
Except for the forensic department, which is doing an autopsy, all other departments are here.
"The action team will talk about the situation first."
Ren Qiang is still recovering at home, and the second action team is still working as an agent for Zhang Hui.
"The camping area where the crime occurred is far away from the city, more than 100 kilometers away. There are no residential areas around it, and the location is relatively remote."
"The entire camp was opened last year It was completed and put into use in March, and it has only taken a year and a half. ""The project is a municipal project. It was planned to start construction eight years ago, but because the investment was not in place, it was delayed for three years. Construction only started five years ago. , the construction cycle also exceeded the original plan, and it took three and a half years to complete. ”
“The person in charge of the construction party has been found. Preliminary inquiry results show that the construction party knows nothing about the stone statue. The specific time when the stone statue was installed in the small amusement park in the camping area was on New Year’s Day last year, at the fountain. It was hoisted in before construction.”
“We are currently looking for the stone supplier who supplied the stone statue through the construction company.”
“All tourists who have visited the camping area have registered their information. But there was no further inquiry. "
Qin Yong nodded. The body was shriveled up and had been dead for more than a year. There was basically nothing suspicious about the people at the scene.
Zhang Hui continued to report: "Judging from the current situation, the stone supplier should be the most suspicious."
"Everyone thinks that this stone statue is more than three meters high and weighs a ton, and it has been tampered with in the middle. The possibility is basically non-existent.”
“And we saw that after the stone statue was broken open, the bottom layer was processed. After the body was put in, the top and bottom were covered with stone, and we couldn’t see any manual cutting. "
"From this point of view, the only person who can tamper with the stone statues is the carving stone merchants."
"So, whoever carves the stone statues has the most. Possibly the murderer.”
Although there are not many investigations done on the action side, the direction is very clear.
Because the carrier carrying the corpse is too special.
There is a corpse hidden inside a stone statue that is three meters high and weighs one ton. This is the first time that all the criminal police involved in handling the case have encountered it.
But precisely because the stone statue is too tall and heavy, apart from manipulating the stone statue during the carving stage, it is difficult to hide the body inside the stone statue without disturbing anyone.
Qin Yong also agreed with Zhang Hui's judgment.
"Operation Team 2 will focus on following this clue tomorrow and be sure to find out the origin of the stone statue."
"Yes!"
This is what Zhang Hui was supposed to do.
"What clues are there in the current investigation?"
Liu Guodong, who spoke, Lu Chuan did not participate in the case analysis meeting this time. He was still doing experiments in the laboratory.
"First, the identity of the deceased has not been determined yet. The forensic doctor is doing an autopsy. We have obtained the test materials and are doing DNA identification and analysis."
"Lu Chuan is also doing an autopsy on the body." Fingerprints have been collected. Although it is relatively difficult, fingerprint comparison is being done.”
“Secondly, we found a corn kernel inside the stone statue, because we do not have the corresponding equipment here, so we have requested it. The seed company helped analyze and identify the origin of the corn.”
While most people were holding a case analysis meeting, in the forensic autopsy room, Wang Changjiang and Shen Yan were analyzing the cause of death and the time of death. Conduct inspection and identification.
“There are no wounds on the surface of the body, and the hyoid bone is broken. It is initially determined that the death was due to suffocation.”
"The corpses were dehydrated in a short period of time, and the weathering time is not very certain."
"Master, there are lumps of insoluble matter in the stomach of the corpse. I will do a toxicology test to see if there is any possibility of poisoning. "
"There is also a liver, take a slice and check it too."
Wang Changjiang and Shen Yan completed this autopsy together.
Because the dried cadaver tissue is stiff, it is impossible to cut through the surface skin with an ordinary dissecting scalpel, so a chainsaw can only be used.
However, this kind of dissection experience is rarely encountered, and mummies are very rare in Haizhou City.
