Facing Lu Chuan's concern, Yang Lin shook his head with difficulty.
Although I saw many corpses when I was studying on-site investigation in school.
And in the process of learning the transformation of corpses, I have also seen many corpses that were extremely decayed.
But pictures are pictures and the scene is the scene.
The picture is not three-dimensional, and there is no smell of blood in the picture.
But this scene is different.
After Yang Lin saw it for the first time, he felt like his stomach was churning and he wanted to vomit.
He even spit out a mouthful and was forcefully swallowed by him.
As for Yang Lin, he can come to work in the investigation office of the Criminal Investigation Detachment.
It’s not about how good his abilities are.
There were three policemen who joined him at the Huaguang Street Police Station.
There were four people who joined the company the year before, two of whom were majoring in on-site investigation.
Among their batch of graduates who were the same as Lu Chuan, only Lu Chuan entered the on-site investigation office of the Criminal Investigation Detachment.
The others are in the police station, the traffic police department, and the anti-drug detachment. In short, they are doing everything.
It was mainly because of Lu Chuan that he was able to join the Criminal Investigation Detachment on secondment this time.
It can be said that it is a good opportunity to study and be seconded this time.
As soon as Lao Bai retires, if there are no problems during his inspection period, he will be able to directly obtain the establishment and stay in the criminal investigation detachment.
You must know that as a police officer, it is the dream of all police officers to work in the criminal investigation detachment.
There is a saying that goes well: To be a police officer, you must do criminal investigation.
So even though he was about to vomit just now, Yang Lin forced himself to hold it back.
He didn't come here to enjoy the blessings, and he couldn't rely on Lu Chuan all the time.
Yang Lin must reflect his own value.
On the one hand, he should make others feel that Lu Chuan was right in choosing him and that there was no favoritism.
On the other hand, he also has to stand firm in the criminal investigation detachment. If just one scene can make him, a current detective, vomit, then he won't have to hang around here in the future.
Of course Lu Chuan could see that Yang Lin was forcing patience.
However, this is a process that every investigating detective must go through.
When he came to the current survey office two years ago, he experienced a similar scene.
But there are some things that he can help Yang Lin with, but there are some things that he cannot help.
You can give yourself the opportunity, but you still have to rely on Yang Lin to work hard.
After nodding, Lu Chuan began to organize an on-site investigation.
The first is to take photos on site.
When he was in the police academy, Yang Lin of course learned spot photography.
But after entering the police station, I basically didn’t use it much.
Photography is rarely used when arriving at a police station scene, and the police pass is used to record the entire process.
Yang Sen pointed out a few points to Yang Lin and asked him to take pictures from these directions.
But before that, Lu Chuan first inspected the ground at the scene.
According to the reporter Li Pingzhang, the Mingde Road church is open once a week.
Opening hours are Sunday morning from 7 am to 12 noon.
Normally no one comes.
Cleaning is done twice a week, once on Sunday after the ceremony, and someone has to come over for cleaning on Friday.
At other times, few people come to the church.
At the door, Lu Chuan lay on the ground, using the sunlight to observe the footprints on the ground.
Yes, and it's very clear.
"Yang Lin, get the chalk."
"Okay."
Starting from entering, Lu Chuan marked the shoe prints in the church one by one.
Prevent yourself from accidentally stepping on it and damaging the traces of the scene when you wait for others to enter later. While Lu Chuan was investigating inside, Zhang Hui was asking the reporter for some details outside.
"Do you know the person who died?"
Even though more than an hour had passed, Li Pingzhang still looked pale and his hands were shaking uncontrollably: "She... Her name is Zhang Cuicui.”
"She is in the fruit wholesale business and often comes to our place to listen to lectures."
"We got to know each other as soon as we went there."
"The day before yesterday, she called me and asked me to call her tonight. She lectured alone...unexpectedly..."
Zhang Cuicui?
The information about the deceased is now confirmed.
But Li Pingzhang didn't know the other information.
About the deceased, he only knew that he had been divorced, but he did not know whether he had any children or what was going on at home.
“Is there a fixed number of people who do the cleaning?”
“Yes, the property management company in the neighboring community helps with the cleaning. Their manager often comes to our place for lectures.”
After confirming the identity of the deceased, Zhang Hui asked the team members to contact his family through the household registration system.
Further investigation into the deceased’s interpersonal relationships.
According to usual experience in solving crimes, in complex and terrifying crime scenes like this, there is often a deep entanglement between the murderer and the victim.
By investigating the interpersonal relationships of the deceased, there is a high probability that some clues can be found.
At the crime scene, Lu Chuan had already marked his footprints.
Now entering the site, other current exploration projects are underway.
"Lu Chuan, the area around here is very clean and there is no blood."
Yang Sen noticed the abnormality immediately.
The victim was nailed to the cross, his hands and feet were inlaid with steel nails, and his neck was tied and fixed with steel wires.
The skin on the front half of the body is peeled off and spread symmetrically to form a shape similar to butterfly wings.
Logically speaking, there should be a lot of blood around such a scene.
However, the blood on the body seemed to have drained away.
There was nothing on the ground, it was as clean as new.
This is not normal.
Lu Chuan put on white gloves and began to examine the body.
“Look here.”
On the deceased's left chest, where the heart was, there was a hideous stab wound under the bloody muscles.
"The stabbing in the heart was the cause of death."
"In addition..." Lu Chuan inspected the wounds nailed to his wrists, ankles and neck.
“The wounds on the wrists and ankles of the deceased had no cutaneous physiological reaction and were postmortem injuries.”
“The wire marks on the neck also had no bruises and were postmortem injuries. ”
Lu Chuan opened the deceased's eyes and found that the corneas were turbid and milky white.
"The crystal is transparent, and the time of death does not exceed 36 hours."
"The corpse is in peak state of rigor mortis, and the time of death exceeds 24 hours..."
Lu Chuan is doing the scene During the investigation, the time of death of the deceased is never determined from just one dimension.
The time of death is determined by comprehensively considering the temperature of the corpse, the degree of rigor mortis, changes in the turbidity of the eye lens, the color of the corpse spots, etc.
The vast majority of on-site detectives can accurately judge the time of death of a body that died within 24 hours to within half an hour.
Lu Chuan can enlarge this time to 7 days.
As long as he dies within seven days, Lu Chuan can accurately determine the exact time of death, and the interval is also half an hour.
As for the longer death time, the accurate interval for Lu Chuan to judge the time of death will become larger.
For example, through the intergenerational growth of maggots after a corpse has decomposed, the approximate time of death of the corpse within three or four months can be determined.
"The skin cuts on the chest also showed no stress reaction. They were all post-mortem injuries."
"This... is most likely not the first crime scene!" (End of Chapter)
