Chapter 559 Another Bloodstain (Please Vote for the Big Chapter)
【Ding! The strongest police training system mission is released. 】
[Detect the case of corpse dumping on concrete. The deadline is five days. Complete the task and you will be rewarded with skills Yang Mandarin Skills. If you fail or exceed the deadline, the task reward will be cancelled. 】
In my mind, the system started task release simultaneously.
This time the reward turned out to be the Yang Mandarin Skills Specialization.
If I had mastered Yangguo during the battle at Huluchang Logistics Park a few days ago, the battle might have been smoother.
Up to now, Chen Yan has only acquired one language skill, which is English Skills.
The Yang Mandarin skill released in this mission is the second language reward.
Calm your mind, although the reward is good, you have to get it.
Field work has concluded.
The body was first discovered in the Third Team, and the office site was in the Third Team conference room.
The head and arms are now undergoing post-mortem examination.
Although there is only a part of the body so far, many clues can still be found from details such as the cutting marks on the body, the scars left on it, and the jewelry worn.
In the conference room, Chen Yan presided over the first case analysis meeting.
The general situation of the case has been reported to the provincial team.
Chen Yan is still handling the case as the leader of the serious crime team.
Liu Qingshan, Zhang Chaoyang, Wang Gang and Zhao Bing were all in the conference room.
There are also Wu Zhiguo, captain of the third detective team, Li Yun, captain of the fourth team, and British case investigators from the two teams.
"Captain Wu, please introduce the general situation of the case."
"yes!"
The third team was the first to receive the alarm, and Wu Zhiguo was naturally the first to report.
"At 8:13 this morning, police officers from the third team received an alarm from the Wanghai Building construction site."
"At 8:25, I led six detectives to the scene and found a head in the transportation pipe of the concrete mortar pump truck."
"According to the preliminary judgment at the scene, the head has long hair, a narrow jawbone, and an earring in the right ear. The victim is initially judged to be a female, with tight skin, and her age is initially estimated to be under 40 years old."
"At the scene, the head and face were severely damaged, and the appearance was unrecognizable. The wound on the broken neck was smooth, and it was suspected that the head and neck were separated by chopping with a sharp weapon."
"Currently, the technical team is conducting an autopsy and DNA identification on the head."
"Captain Chen, this is probably the situation."
Chen Yan nodded and turned to look at Li Yun: "Captain Li, please continue the report."
"yes!"
"At 8:54 this morning, the jurisdiction received an alarm. At the construction site of Kangmingyuan Community, a relocation residence, workers found a severed arm while pouring concrete mortar."
"The arms are slender, there is a ring on the thumb of the right hand, the nails have traces of manicure, and the skin is fair. It is initially judged that the deceased is a young woman."
"After on-site analysis, it was initially determined that the arm should have been transported into the construction site by a concrete mixer truck. It belongs to the same commercial concrete company as the concrete mixer truck where the head was found by the third team."
"Currently, DNA testing is also being done on the arm, and it is initially determined that the deceased's head and head should be of the same person."
"Does anyone else have anything to add?"
Liu Qingshan raised his hand and said, "Let me tell you about the on-site investigation."
"The bodies at both sites were transported by concrete mixer trucks, and according to the investigation results of the Yuanfang Commercial Concrete Company, both concrete mixing vehicles left after loading concrete from the No. 9 Concrete Mixing Station."
"Based on this, it can be judged that the murderer should have dumped the body at the No. 9 concrete mixing station of Yuanfang Commercial Concrete Company, and then the body would be transported to different construction sites by a concrete mixer truck."
"At the construction site, we interviewed all the people who came into contact with the body, and there were no valuable clues. It was probably discovered by chance."
"We conducted a preliminary investigation on the two mixer truck drivers."
"Both of these two people pull and load concrete all year round. They are just drivers. The owner of the vehicle is someone else. They are both affiliated with Lu Yuan Transportation Company. In the past three years, they have been pulling and loading concrete at Yuanfang Shang Concrete Company and sent them to All major construction sites.”
"At the No. 9 mixing station site of Yuanfang Commercial Concrete Company, we discovered
The deceased's clothes and large blood stains proved that Mixing Station No. 9 was the first place where the body was dumped. "
"However, the scene was open and unobstructed, so it was not a murder scene."
"Another point is that judging from the blood content on the protective cover of the transport belt, the murderer definitely not only dumped the head and right arm, but also other parts."
"But so far, we have not received any other reports."
"Any more?" "That's all for now."
Chen Yan nodded, Liu Qingshan's supplement was more detailed and important.
Especially the last point, there were large blood stains on the protective cover on the transport belt, which obviously could not be left by a head and a severed arm.
So, where do the rest of the bodies go?
"If you haven't added anything yet, I'll start assigning the next tasks."
"The first is to determine the identity of the victim."
Chen Yan looked at Wu Zhiguo: "Captain Wu, we need to conduct DNA identification on the head and arms as soon as possible to compare the DNA information."
"Comparisons in missing persons databases."
"On the other hand, we found half a torn coat inside the protective cover of the conveyor belt of the No. 9 concrete mixing station of Yuanfang Commercial Concrete Company."
Turning on the projector, what was displayed was the white card Liu Qingshan mentioned just now.
"This card has the words Tianzhang Building printed on it in the upper left corner. Send someone to check the origin of this card."
"Tianzhang Building is the most famous office building in the financial CBD district of Kunlun Road, Liancheng. This card is most likely the building's access card."
"See if we can find out the identity of the victim through the access card."
"yes!"
Tianzhang Building is also within the jurisdiction of Wu Zhiguo's third team, so it will definitely be more convenient for him to investigate.
Operating the projection, this time it shows the earring found in the right ear of the deceased's head, as well as the broken clothes found in the protective cover.
"The earring in the deceased's right ear is the Cartier brand's flagship model this summer, the cheetah earring."
Enlarge the picture: "This kind of earrings are very expensive, priced at about 30,000 yuan each."
"There are also clothes worn by the deceased. Judging from the material, they are made of mulberry silk. The trademark on half of the collar is still there."
"Chaoyang, please investigate these two clues. There is only one Cartier jewelry store in Liancheng. Check to see if this earring is sold here."
"Generally speaking, people who buy this kind of luxury goods are members, and there is a high probability that they can find some relevant information." "And this coat, according to the brand, check which store sold it. This kind of top made of mulberry silk is relatively expensive, so not many people will buy it.”
"Yes, I promise to complete the mission."
Chen Yan nodded. For Zhang Chaoyang, it only took a few hours to figure out this trivial matter.
Operating the projection, what appeared on it was the deceased's right hand.
The ring on the little finger is made of pure gold, but it does not have any logo, and the style is very ordinary, not a famous brand.
This and the Cartier earrings found on the head, and the coat made of mulberry silk.
It doesn't match. In fact, that coat is worth much more than this ring.
How could a person wearing Cartier earrings wear such a simple gold ring?
Chen Yan has a very detailed understanding of luxury goods, and the wearing of some luxury goods is actually very particular.
The jewelry found on the victim was a bit strange.
******************
Generally speaking, luxury goods in the jewelry category are mainly bracelets, rings, and necklaces.
Why, because these categories of jewelry are very easy to identify.
Why do women wear luxury goods?
To put it bluntly, isn’t it just to satisfy the inner need to express yourself?
Therefore, the best-selling luxury goods are bracelets, rings and necklaces.
As for earrings
Because there are very few people who pay attention to it, if they buy jewelry in this area, either they are really rich and don't care, or they have some other special reasons.
Such as being low-key.
Yes, low-key, some people
For some reasons, it is impossible to wear luxury jewelry in obvious parts, so earrings are a good choice.
People who know the goods carefully will naturally find it, but most people will not see it.
So, what is the purpose of the victim wearing these expensive and inconspicuous luxury earrings, but wearing a simple, old and ordinary gold ring on the little finger of his right hand?
A low-key show off?
"Third," Chen Yan looked at Liu Qingshan: "We must find out all the mixer trucks transporting concrete mortar from the No. 9 Concrete Mixing Station of Yuanfang Commercial Concrete Company."
"From the analysis of the blood stains on the protective cover of the stone conveyor belt of the mixing station, the murderer should have cut up all the corpses and placed them on this conveyor belt."
"Then it enters the mixing station, and then it is loaded into a mixer truck and taken to the construction site."
"We need to find out what these construction sites are and whether there are any body parts that have not been found."
"We also need to conduct an in-depth investigation into this Yuanfang Commercial Concrete Company."
"Why did the murderer dump the body in the concrete mortar mixing station of Yuanfang Shangconcrete Company? Is it to disperse the body or to hide the body?"
"Did Yuanfang Commercial Concrete Company just find a random way to dump the body, or did they deliberately target this company?"
"Master, you are responsible for this matter."
"Ok, no problem."
In fact, this is also a question Liu Qingshan has been thinking about.
After the murder, why did the murderer cut up the body? The purpose should be to throw it away.
The answer is why should he choose a concrete mortar mixer truck?
Why did you choose Yuanfang Commercial Concrete?
Concrete mortar mixing is a highly polluting industry. After all, it causes dust pollution and huge noise pollution. Most of them are built in suburbs, far away from residential areas, but the transportation must be relatively convenient.
On the one hand, it is convenient to transport stone raw materials, and on the other hand, it is also convenient for mixer trucks to transport finished concrete.
More than ten years ago, in order to regulate the commercial concrete industry, Liancheng City carried out special management work.
In the entire Liancheng, only commercial concrete companies exist in the western and northern suburbs. Surrounded by the sea to the south and east, all polluting companies have long been eliminated.
In the northern and western suburbs, most commercial concrete companies have also planned construction land.
For example, Yuanfang Commercial Concrete Company. In addition to this concrete mixing company, there are 12 other companies nearby.
From a geographical point of view, Yuanfang Commercial Concrete Company is in the middle, with commercial concrete companies on the left and right sides. So from the perspective of the convenience of dumping the body, it is not particularly suitable for the murderer to choose Commercial Concrete Company.
The two leading companies are obviously more suitable because the probability of being discovered is smaller.
Therefore, there is probably a problem here.
Chen Yan paused and looked at Liu Qingshan again: "According to the gate security personnel of Yuanfang Commercial Concrete Company, there were no outside vehicles entering the company yard last night."
"The murderer dumped the body, and it is unlikely that he was walking with the body on his back. Therefore, the mixer truck driver who entered the Shang Concrete Company last night is suspected."
"These people need to be investigated carefully."
"Okay, don't worry, I'll push forward as soon as possible." This is the end of the first case analysis meeting.
There is only a head and a severed arm, and there is too little relevant information.
Not only that, both the arms and the head had been tumbling in the mortar for too long. Even if the murderer left any traces, they have long since disappeared.
Now, we can only start with the identity of the deceased.
An hour later, the autopsy report on the head and arms of the deceased was delivered to Chen Yan.
Wu Zhiguo began to report.
"Team Chen, the head and face were severely damaged, and it is impossible to directly restore the deceased's appearance during life."
"I have sent technicians and portraitists to repair the face, but this may take a long time."
"Have the DNA comparison results come out?"
The condition of the head is clearly stated, because it was rolled and stirred back and forth in the mixer truck, and it had long been changed beyond recognition.
Wu Zhiguo nodded: "This has come out. The deceased is a woman, and the head and arms belong to the same person."
Chen Yan read the autopsy report carefully.
According to the degree of wear of the molar teeth of the deceased, the initial
The deceased was judged to be between 25 and 35 years old.
This time, the gap in age estimation is a bit wide, because only the head of the deceased was found, and no other bones such as hip bones were found for verification.
Therefore, the youth bias is larger.
The time of death should be between 8pm and 10pm last night.
No fingerprints or other traces were found on the head or arms.
The wounds were judged to be the separation of the body caused by ax blows.
As for the cause of death of the deceased, it is still unclear because there are few parts of the body.
However, based on some characteristics of the fundus of the eyes and the condition of the skin on the neck, the possibility of death by suffocation is basically ruled out.
"Is there any other information?" "There is also important information." Wu Zhiguo handed over another report.
"We tested the blood stains on the protective cover of the stone transport belt of the No. 9 mixing station of Yuanfang Commercial Concrete Company."
"This is the test report."
Chen Yan took the report, glanced at the information above, and his pupils suddenly dilated.
"Two people?"
"Yes, the bloodstains on the protective shield belong to two people. One of them has the same DNA information as the head and arms, but we have detected the DNA information of the other bloodstain and it is a male."
The DNA information of another person is still a man.
"How much blood volume is there?"
Wu Zhiguo knew that what Chen Yan meant was the extent of the blood stains belonging to that man.
"It is similar to the deceased, and there is a large blood stain remaining. This blood stain should not belong to the murderer."
Chen Yan frowned.
If the amount of blood stains is very small, it is likely that the murderer accidentally cut his hand while throwing the body, resulting in residual blood stains.
However, if it is a large blood stain.
That means there is probably another victim!
"Come on, take me to the examination room to have a look."
In the examination room, the blood-stained protective cover has been taken back.
The technician was gesturing to Chen Yan: "The blood stains in this area belong to that male."
"In addition, here, there are also blood stains of two people superimposed on each other."
The superimposed blood stains are on the protective cover of the fourth quarter. No one can go up to this height.
Therefore, judging from the blood stain analysis, there must be another victim!
call!
Chen Yan let out a deep breath. Two people were killed, a man and a woman.
And judging from the overlapping blood stains, the other party should have dumped the body at once.
It is absolutely impossible for the other party to carry two corpses with bare hands, otherwise, they will be discovered on the road.
You should know that mixer trucks are transported 24 hours a day on the road to and from Yuanfang Commercial Concrete Company.
If a person is carrying something in the middle of the night, he will definitely be discovered.
And last night, there were no strange vehicles entering or leaving the yard of Yuanfang Commercial Concrete Company.
Now, it is basically certain that it was the mixer truck driver who dumped his body.
Taking out his cell phone, Chen Yan dialed Liu Qingshan's number.
Explained the existence of the second victim to Liu Qingshan.
"Master, all the drivers of concrete mortar mixer trucks operating at Yuanfang Commercial Concrete Company from 8 o'clock last night to 8:30 this morning will be summoned for summons."
