Chapter 152 Traces of Rolling
There are many ways to judge the basic information of the corpse.
For example, age can be determined based on the degree of tooth wear and bone age testing.
Even, it can be judged based on the shape of the skull.
For example, in adolescents before the age of twelve, due to skeletal hypoplasia, the skull is not completely closed.
Based on the size of the gap, the specific age range can be determined.
Many indicators of autopsy and excavation must be combined and analyzed together.
Results Multiple judgment criteria can accurately determine the basic information of the deceased.
Although Lu Chuan does not have a forensic skill card, his intermediate field investigation skills are all-encompassing, and there is no problem in attacking Shen Yan.
In less than two hours, the basic information of the deceased was sorted out.
Female, aged between 35 and 40 years old, 1.63 meters tall and weighing about 50 kilograms.
The time of death is within forty-eight hours, and the cause of death is uncertain.
After death and before dismemberment, the body is refrigerated for a short period of time.
“Why did the murderer freeze the body for a short period of time?”
As for the freezing of the body, the murderer should have started before rigor mortis had fully occurred.
In fact, the scene of the first crime may even be in a low-temperature environment.
Generally speaking, most of the purpose of freezing corpses is to hide them, but the murderer does not seem to have this idea.
Otherwise, he would not have thrown the corpses all over the streets.
Shen Yan’s question is something Lu Chuan has been thinking about.
“Judging from the cut marks on the body, the degree of freezing is indeed not deep. It seems that the blood has just been able to coagulate...”
Um?
Blood coagulation!
Lu Chuan and Shen Yan looked at each other and said in unison: "It's convenient to dismember the corpse!"
Dismembering the corpse is not a simple job, it requires not only technology, but also physical strength.
Just like cutting meat in the kitchen, soft meat is difficult to cut, and frozen hard meat is also difficult to cut.
However, slightly frozen meat will be very silky when cut, and there will be no blood stains left.
Did the murderer micro-freeze the corpse just to make it easier to dismember it?
Conference room.
"Team Qin, the identity of the deceased has been found!"
Qin Yong, who was conducting the deduction of the murderer's corpse, was shocked.
"What's going on?"
Liu Guodong took the fingerprint identification analysis report that Lu Chuan had just done: "The deceased's name is Wang Guizhi, from Haizhou City. His family reported him missing two days ago."
On the projector , it is the analysis report that successfully compared the fingerprints extracted from the finger stumps of Wang Guizhi and the deceased.
To analyze this fingerprint, Lu Chuan did not need to perform any processing at all, and the system gave a successful comparison result in less than two minutes.
"Wang Guizhi, female, 37 years old, cleaning worker at the Northern Meat Federation Slaughterhouse. Two days ago, Wang Guizhi did not come home after get off work, and his husband reported her missing."
Basic information about Wang Guizhi is being displayed one by one.
Northern Meat Federation?
This is the largest local livestock slaughtering and processing enterprise in Haizhou City, basically monopolizing nearly half of the Haizhou slaughtering industry.
"Where did Wang Guizhi disappear?"
"The North Market Police Station received the case. On the day of the incident, the police station sent people to check the surveillance video of Wang Guizhi's usual walk home. ”
"The other party got on the bus he usually takes and then disappeared."
"What time?"
"It's 6:42 pm. Wang Guizhi usually gets off work at this time. Then we took the bus in front of the meat factory and went home."
"What do you think?"
The identity of the deceased has been confirmed. It can be said that there has been a breakthrough in the investigation of the case.
According to regular procedures, the police will search Wang Guizhi's social circle for investigation.
Sure enough, Ren Qiang put out the cigarette in his hand and was the first to speak: "I think we should divide our forces into two groups. On the one hand, we will figure out Wang Guizhi's interpersonal relationships."
"From Judging from the current situation, Wang Guizhi's job and family economic conditions are average, and the possibility of murder for money or love is not high. "The possibility of an acquaintance committing the crime is still higher."
Ren Qiang has experienced many murder cases and has rich experience.
In some murder cases, a close guess can be made just as to the identity of the deceased.
Wang Guizhi’s situation is obviously not a murder of love or murder for money.
As for killing with passion, dismemberment is not a good choice.
So, if you look into Wang Guizhi’s interpersonal relationships, the probability of solving the case is higher.
“What about the second one?”
"The scene."
Ren Qiang answered quickly: "Judging from the location of the plastic bags we found at the scene, the other party dumped the bodies from one end of the folk street to the other end."
"And the boss of Tongguan Master Roujiamo also hired him. The body parts found in their store were picked up from the door when they opened in the morning."
Ouch!
When Ren Qiang said this, everyone looked at Wang Shuai, who was the first to discover the case.
At this moment, Wang Shuai's face was pale, as if he was suppressing something.
As a result, Wang Shuai still couldn't hold him down, he retched and ran out again.
The reason is very simple. The meat of Young Master Tongguan’s Roujiamo is not clean.
In order to save costs, the boss uses the cheapest expired frozen meat in the frozen market.
What is expired frozen meat? It means meat that has been thawed and then frozen again.
This kind of meat is cheap and has large profit margins.
During processing, even if there is a little odor and some technologically advanced seasonings, most people will not be able to taste it.
This morning, I happened to catch a batch of meat coming into the store, which happened to be packed in black plastic bags.
The shopkeeper mistook the murderer’s body bag still in the gutter in front of his house for the meat they purchased.
“He thought it had fallen while carrying it, so he picked it up and took it back for processing.”
All the chefs in the back kitchen can testify to this matter, and neither the owner nor the chef had enough time to commit the crime.
No human blood was found on the floor or walls of the kitchen.
In Kanli, there is a strict process for detecting blood stains.
First, we must first determine whether it is blood stains.
Dried blood stains will change from red to dark red, brown or even colorless as time goes by.
Second, after determining the blood stain, it is necessary to determine whether it is human blood or animal blood.
Human blood and animal blood stains can be distinguished through experiments because of their different compositions.
Lu Chuan found no trace of human blood in the back kitchen of the Roujiamo shop.
As for Wang Shuai who was vomiting... he used to frequent this Roujiamo shop.
After this happened, who knows what else I have eaten before...
Now I can still bravely participate in handling cases, which is already a perfect score for professional ethics.
"I think what Lao Ren said makes sense. The places where the other party dumped their bodies are all in Yanbian, Folk Street."
Sun Jun continued to speak.
“These are the location marks of the seven plastic bags for dumping corpses. Including the ones from the Roujiamo shop, there are eight bags in total.”
When Sun Jun talked about the Roujiamo shop, Wang Shuai, who had just finished vomiting, came in.
vomit!
Wang Shuai suddenly felt that the world today was full of malice towards him.
As for that, didn’t I just eat a few meat buns?
But the feeling of chewing my fingernails in my mouth... is so disgusting.
“If you look at the distance between these bags, they are basically about two hundred meters apart.”
The projection switches to a picture of the scene where the body bags were found: "Let's take a look at the traces of these bags rolling down."
