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

Chapter 524 Case Analysis Meeting

The stone statue containing the corpse is hollow inside, and 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. As time goes by, the oil and sweat evaporate, and the fingerprints will disappear naturally.

Under normal circumstances, the time that fingerprints remain outdoors is relatively short. Due to sunlight exposure and air flow, the sweat and oil on fingerprints will generally evaporate completely in less than half a month, making them impossible to detect and even 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.

Unfortunately, there are no fingerprints left inside the stone statue, but it is not without any findings.

"Is this...corn kernels?"

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 inside this stone statue?"

Lu Chuan frowned and was a little confused about this: "Take it back for testing first. It is impossible for the corn kernels to appear in the stone statue out of thin air. There is a high probability that the corpse brought it 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 in terms of protein content, species produced in different origins vary greatly, and have relatively strong regional characteristics.

However, Lu Chuan only has some understanding and does not know much about these aspects. He may need technical support from the seed industry department.

The on-site investigation work will continue until after 9 p.m. and will be completed.

Because the stone statue was too bulky, there was 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 had already transported the body back for autopsy.

When Lu Chuan and others returned to the detachment, it was already 11:30 pm.

"Inform all departments and hold a meeting first to get to know each other."

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 Zhang Hui is still working as an agent for the second operation team.

"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 built and put into use in March last year, and it has only been a year and a half now." "The project is a municipal project. It was planned to start construction eight years ago, but because the investment has not been in place, it has been delayed for three years. Construction only started five years ago, and the construction cycle exceeded the original plan, taking 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, and it was hoisted in before the construction of the fountain. .”

"We are currently looking for stone suppliers through the construction company to supply the stone statues that year."

"All tourists who have been to the camping area today have registered their information, but no further inquiries have been made."

Qin Yong nodded. The body was already shriveled. It had best been dead for more than a year. There was basically nothing to suspect 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 one ton. There is basically no possibility that it was tampered with in the middle."

"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. There were no traces of manual cutting."

"From this point of view, the only ones who can tamper with the stone statues are the merchants of the carved stones."

"So, whoever carved the stone statue is most likely to be 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 was a corpse hidden inside a stone statue that was three meters high and weighed one ton. This was the first time that all the criminal police involved in handling the case encountered it.

However, 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 corpse inside the stone statue without alerting anyone.

Qin Yong also recognized Zhang Hui's judgment.

"Operation Team Two 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 originally wanted 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 also collected fingerprints from the corpse. Although it is more difficult, the fingerprints are being compared."

"Second, we found a corn kernel inside the stone statue. Because we don't have the corresponding equipment here, we have asked the seed industry company to help 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 examining and identifying the cause of death and time of death of the corpse.

"There are no injuries on the surface of the body, and the hyoid bone is broken. It is initially determined that the death was due to suffocation."

"The bodies 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 corpse's stomach. I'm going to do a toxicology test to see if there is any possibility of poisoning."

"And the liver, cut it into slices and check it too."

This time the autopsy was completed jointly by Wang Changjiang and Shen Yan.

Because the dried cadaver tissue is stiff, it is impossible to cut through the surface skin with an ordinary dissecting scalpel, so an electric saw can only be used.

However, this kind of dissection experience is rarely encountered, and mummies are very rare in Haizhou City.
