Chapter 378 Case Discussion
Since the test materials for trace physical 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 each inspection material carefully.
“The fiber test result came out, it is 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 soil from Beishan belongs to our Beishan."
The soil in each place has different characteristics and ingredients. The soil in Beishan, Haizhou City is a kind of clay that can be used to make bricks and tiles.
"Beishan..."
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 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 9:30 p.m., 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, it is routine work to state the autopsy report. He had 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 heart, and she died of excessive bleeding. No trace of violation was found on the body, and there was a history of freezing."
"The body was frozen from the end It must have taken more than a month before it was discovered by scavengers at the garbage dump.”
"The reason is that the corpse has serious mildew, and there are moldy areas in the armpits, face, arms and inner thighs."
"In addition, the corpse should be frozen for more than a year, because There are layers of mildew on the surface of the corpse, which means that the corpse had mildew in the frozen state before it became moldy in the garbage dump."
"The time of death...the specific time is difficult to determine now. Accurate judgment, but it is estimated to be no less than a 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 nothing we can do 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.
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 looking at 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.
Only based on mildew in the frozen state, a death time that should be no less than one year can be given.
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 has been determined. He disappeared more than a year ago.
So, 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 his 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 did not have many clues, although the clues from the current investigation did not directly point to the murderer, they can 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, thirty years old. Two years old, from Huangzhou City, reported missing in March last year, it has been one year and three months now.”
Liu Guodong has not followed up on the disappearance case and has already reported it to the action team, so the focus of his report is. Not here.
"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."
The 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 identification of trace evidence, 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 clothes.”
“Also, we found some soil residue in the box After testing, it can be determined that the soil comes from Beishan, Haizhou City.”
"Beishan?"
Liu Guodong paused his report while the participating members were communicating with each other.
“That side of Beishan...it used to be a brick and tile factory, right?”
“Yes, there is clay in Beishan. In the past, Beishan was a brick and tile factory, but later due to environmental pollution problems due to substandard environmental protection We can’t figure it out, they’ve all been demolished. In recent years, a refrigerated logistics park has been built there because it’s close to a highway and a beltway.” Refrigerated in the garden?”
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 forensic doctor, the body had become moldy while it was frozen. , this situation 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 not survive. It will lose its activity.”
“We suspect that the location where the corpses are refrigerated has experienced multiple losses of temperature, which will lead to the growth of moldy fungi.”
“This happened in large cold storages. The probability of this situation is not high. It may be possible in small refrigeration places such as cold chain transport vehicles.”
"Of course, the cold chain transport vehicle I'm talking about is just one of them. For example, some hotels or restaurants may have self-built small cold storages or even freezers. This is also possible."
At present, although there is no A clear decisive clue, but 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, and 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."
Ahem.
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 gains were not very big.”
