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

Chapter 378 Case Discussion
Since the testing materials for trace evidence are very limited, and most of them are measured in grams and milligrams, the requirements for the experiment are very high, so there is no possibility of a second trial and error.

Liu Guodong and Yang Sen handled every inspection material carefully.

"The fiber test results came out, it's colored cotton."

"Colored cotton? This thing is not cheap."

During the Chinese New Year, Lao Bai bought a set of colorful cotton underwear, which cost several hundred dollars.

“How about the soil testing?”

"The ones from Beishan belong to us from Beishan."

The soil in each place has different characteristics and composition, and the soil in Beishan, Haizhou City is a kind of clay that can be used to make bricks and tiles.

"North Hill……"

Lu Chuan had never been there, but Lao Bai was familiar with that place.

"There were many brick and tile factories in Beishan in the past few years, but later they were all moved away due to environmental pollution. I remember that a cold storage logistics transfer base was built there in the past two years."

cold storage?

The body showed signs of freezing. Could it be that the body was frozen in Beishan?
At 909:30 in the evening, Qin Yong organized the first case analysis meeting.

The conference room was filled with smoke. Lu Chuan was sitting in the corner. Looking at the people in the first row, he knew that the emotions of the people in the first row were not particularly high. The investigation of the case was not as smooth as expected.

"Forensic doctor, Lao Wang, please tell me first what the autopsy found."

In the past, Wang Changjiang was relatively calm when he spoke. As a forensic doctor, presenting the autopsy report is a routine task. He has done it countless times, but this time he looked embarrassed.

"Female, the cause of death was that the chest was pierced with a sharp instrument, hitting the center of the heart. She died of excessive blood loss. No trace of violation was found on the body, and there was a history of freezing."

"It should have taken more than a month for the body to end its frozen state and be discovered by scavengers at the garbage dump."

"The reason is that the body suffered from severe mildew, and there were mildew areas on the armpits, face, arms and inner thighs."

"In addition, the corpse should be frozen for more than a year, because there are changes in the level of mold on the surface of the corpse, which means that the corpse had mold once in the frozen state before it became moldy in the garbage dump."

"The time of death...it is difficult to accurately judge the specific time now, but it is estimated to be no less than one year."

Wang Changjiang has worked as a forensic doctor for so many years and has rarely come up with such specious conclusions.

However, there is really no way this time.

The time of death of a corpse is very easy to judge in the initial period of time.

For example, the accurate time of death of the corpse can be obtained through the temperature of the corpse, the degree of rigor mortis, the color of the corpse spots, etc.

In fact, even skeletons without flesh and blood have certain advantages in judging corpses.

Only for frozen corpses, Wang Changjiang basically determined the time after thawing by checking the changes in internal organs and residual gastric contents after dissection, but he could not accurately determine the length of time the corpse had been frozen.

A death time that should be no less than one year can only be given based on mildew in the frozen state.

This range is too large.

In other words, the autopsy does not seem to have much effect on advancing the case.

The fingerprints of the deceased were successfully compared and the identity of the deceased was determined. He disappeared more than a year ago.

Therefore, it is possible that the victim died for more than a year, or more likely, he died for more than a year and then remained frozen.

It was not until last month that the murderer dumped the body in a garbage dump. "The forensic doctor has finished talking. Let's investigate now. Lao Liu, please tell me."

Liu Guodong cleared his throat. Compared with the forensic doctor who didn't have many clues, although the clues from the current investigation did not directly point to the murderer, they could be described as rich.

"First, the identification and analysis of fingerprints. Lu Chuan completed the identification and analysis of the victim's fingerprints and successfully compared the identity of the deceased."

"The deceased's name is Wang Lili, female, 32 years old, from Huangzhou City. She was reported missing in March last year. It has been one year and three months now."

Liu Guodong did not follow up on the disappearance case and had already reported it to the action team, so that was not the focus of his report.

"At the same time, we tested the DNA of the deceased and successfully compared it with the DNA provided by Wang Lili's parents in the disappearance case."

Both fingerprints and DNA were successfully compared, so there is definitely no problem with the identity of the deceased.

"In addition, we found a kind of fiber on the body of the deceased and in the suitcase containing the body. After trace evidence identification, it was determined to be a type of colored cotton produced in New Zealand."

"This kind of cotton is very breathable and warm, but the output is not large, so the price is higher than that of ready-made clothing."

"Also, we found some soil residues in the box. After testing, we can confirm that the soil comes from Beishan, Haizhou City."

"North Hill?"

Liu Guodong paused his report while the participating members communicated with each other.

"That side of Beishan...it turned out to be a brick and tile factory, right?"

"Yes, there is clay in Beishan. Beishan used to be brick and tile factories. Later, because the environmental protection standards were not up to standard and the environmental pollution problem could not be solved, they have been demolished. In recent years, because there is a highway and a ring road nearby, they have been built there. A frozen logistics park.”

"The opinion of the current investigation...is it suspected that the body was refrigerated in the refrigerated logistics park?"

Liu Guodong nodded: "It is possible, but we do not rule out other possibilities, such as cold chain transport vehicles."

"According to the autopsy results from the medical examiner, the body had been moldy while it was frozen. This is actually very rare."

"The basis for the occurrence of mildew is the presence of moldy fungi. Under normal freezing and low temperature conditions, moldy fungi cannot survive, or even if they survive, they will lose their activity."

"We suspect that the location where the bodies were refrigerated had experienced multiple hypothermia events, which would have led to the growth of mold and fungi."

"The probability of this happening in large cold storages is not high, but in small refrigeration places like cold chain transport vehicles, it may be possible."

"Of course, the cold chain transport vehicles I'm talking about are just one of them. For example, some hotels or restaurants may have self-built small cold storages or even freezers. This is also possible."

Although there are no clear decisive clues in the current investigation, the location of Beishan still provides possible directional clues for the investigation of the case.

At the very least, the task force can now confirm that the body once stayed in Beishan, or was even put into a box in Beishan.

"Is there anything more to add to the current survey?"

Qin Yong looked across the crowd and glanced at Lu Chuan in the second row.

Seeing that there was no reaction from the other party, he continued to host the meeting: "Okay, action team, Ren Qiang, you are responsible for visiting and investigating. Let's talk about the situation first."

cough cough.

Ren Qiang coughed twice and moved his butt.

"After the incident, we deployed a large number of manpower and, with the cooperation of the local police station there, visited several surrounding villages, but the results were not very great."
