"What's wrong," Wu Duan asked.
"Men of culture."
As he spoke, Yan Sixian's nose was almost touched by the truncated finger, and of course, there was also a thin layer of evidence bag.
"You mean the deceased," Wu Duan also stepped forward to look at the severed finger.
"The middle finger of the right hand, you see this callus, it is left by holding the pen for a long time."
Yan Sixian said.
"Not really."
Wu Duan stretched out the middle finger of his right hand.
He just wanted to give Yan Sixian an example, but after making this gesture, he realized that it was indecent, so he simply stretched out a few fingers.
"Ahem, you see, I haven't held a pen for many years, but the calluses on my hands are still there, not only calluses, I held the pen too hard when I was in school, and the knuckles at the end of my right middle finger are even a little crooked, which can be seen quite obvious."
Yan Sixian stretched out his hand and rubbed it on Wu Duan's knuckles for a moment.
"It's different."
He said, "You obviously left it many years ago, the calloused epidermis has grown as delicate as the skin of other parts, he can clearly see that the epidermis is still very rough, it is freshly polished."
In other words, he was still using his pen a lot before he died. ” "Is it a student who uses a pen a lot?"
"It's hard to say, but the nails were neatly trimmed, indicating that the deceased was a person with good hygiene habits, and the dead skin on the edges of the nails was carefully removed, indicating that the nails may not have been trimmed by themselves, but went to the nail salon to maintain the nails" "Is it a woman" Wu Duan said: "No, this finger looks thick, and the nail cover is also big, it looks like a man." ” "There are also men who do manicures outside, and I've seen quite a few of them.
Look at the dead skin around the nails, and go clean. ” Yan Sixian stretched out his hand and compared it with that finger.
Wu Duan finally saw the difference.
He has to admit that the difference between the two is quite obvious.
"Okay, so this is a man who is willing to spend money on manicures, either belongs to the kind of successful person who has money and leisure, or is a man who pays a lot of attention to appearance, or a woman."
Wu Duan always felt that this summary was very awkward, so he simply observed the severed finger with all his heart, trying to observe the age of the deceased from the delicacy of the severed finger skin, but the frozen finger skin was pale, and there were unnatural folds in the belly of the finger, which was really hard to say.
He had no choice but to give up.
"Wait for the results of the forensic examination, it is strange for them to be so small."
Mink Fang, who had just entered the scene, happened to hear Wu Duan's words, and continued: "Don't worry, there should be more information that can be detected than you think, after all, you forgot that the murder case in Mingchang Park only had an incomplete DNA sample, didn't the murderer catch it anyway?"
Yan Sixian smiled bitterly, "Your ability to comfort people is with the old university."
Mink Fang shrugged and took the evidence bag, "I'll bring the things back, and I'll inform you as soon as there are results." ” After 3 hours of searching, nothing was found, and Wu Duan ordered the team to be closed.
Although the criminal police were also anxious about the case, they were relieved that they didn't have to continue to work in the wind and snow.
Four people in a car, as soon as they got into the car, they were covered in cool air, and the temperature in the police car immediately dropped a lot.
When Wu Duan returned to the car, he also rubbed his hands vigorously.
Yan Sixian turned on the heater and turned on the heating function of the seats for the two to the maximum.
Wu Duan stretched out his hand and adjusted the temperature of the seat down, "I'll slow down, I don't need you high-end things." ” "Just get used to it."
"I can't get used to it, I'm afraid of wetting the bed at night."
"Hah" "As the old saying goes, children tend to wet the bed when their buttocks are hot, and when I was a child, my grandmother always said."
Yan Sixian snorted and let him adjust the temperature by himself.
Wu Duan brought the topic back to the case, "Let's find a way to determine the source of the corpse first, it's not right, it's too early to talk about the source of the corpse." ” "You think the owner of the finger may still be alive" "Hmm.
About 15 years ago, there was a similar case, and it was reported nationwide, and when I was in school, that case was written into the textbook as a case.
In a southern province, there was a gang of murderers who robbed motorcycles, and their methods were really cruel and vicious. not only grabbed the bag, but also used a machete to cut the joint of the lost owner.
Because at the moment when a person is robbed, many people's subconscious reaction is to grab their bag.
Many of the victims, whose hands were cut off had been grabbed on the bag belt, were directly taken away by the murderer and disposed of, missing the best time to connect their limbs and leaving them disabled for life.
Some people's hands are found in garbage cans in remote parts of the city. ” Yan Sixian rubbed his chest, such news made him feel sullen in his heart.
"Happy people are all a pattern, unfortunate people, and the misfortunes they experience are strange.
Who would have thought of the helplessness, surprise and despair experienced by the victims when their bodies were instantly detached.
Maybe one second you are happily preparing for work, further education, marriage, and travel, and the next second you will be able to " Yan Sixian stopped, "I'm sorry, I forgot the basic principles, don't overly substitute the emotions of the victims." ” "It's okay, understand."
Wu Duan said: "I saw this case at the time, and I didn't sleep well for a week. ” Yan Sixian was determined not to discuss in depth, "I understand what you mean, you want to say that the current case will be the same as the speeding car robbery, a case of intentional injury." ” "I hope so."
After eating at noon, Wu Duan's wish was shattered.
In the autopsy room, Mink Fang, Wu Duan, and Yan Sixian gathered together, looking at a severed finger and a piece of meat in the iron plate.

"I haven't had time to write the report, so I'll tell you about it first."
Mink Fang said, "People are already dead, and there is no reflection of life on their fingers or flesh.
I speculate that the biggest possibility is that after the murderer kills the person, freezes the person, slowly cuts it into small pieces or small pieces, and throws it away little by little, so that it is difficult to be found, after all," Mink Fang pointed to the meat slices, "This kind of thing, most people will think that it is wasted food when they see it."
Also, now our municipal sanitation is also more advanced, generally using that kind of automated garbage truck to dump or recycle garbage, manual operation is very rare, the probability of being found is even smaller. ” "Basic information about the deceased, gender, age, etc."
Wu Duan reminded.
Mink Fang picked up the notebook on the table, "Male, about 55 to 57 years old, the finger is the middle finger of the right hand, and the flesh is preliminarily judged from the muscle distribution, it is the meat on the outer thigh of the right side."
Through the state of the meat slice, a preliminary judgment can be made about the body fat content of the deceased.
The deceased had a high body fat content, and was probably fat, at least that kind of middle-aged state, you know."
"Understood."
Wu Duan said: "What about the health of blood lipids in all aspects?"
"The forensic laboratory is waiting for the report to come out, you can read the report directly, the data is more intuitive.
I would like to highlight the following two pieces of information. ” Mink Fang paused, and Wu Duan nodded, indicating that he had listened to the key information.
"First, I extracted a small amount of calcium carbonate and calcium sulfate powder from the fingernails of the corpse."
Wu Duan frowned, saying that the chemistry knowledge he learned at the beginning had basically been returned to the teacher.
But he pulled out his phone and wanted to check the characteristics of the two substances.
"Chalk Ash" Yan Sixian gave the answer directly, "Is it a teacher?"
"Maybe," Wu Duan said, "However, in addition to schools, there are actually some places where chalk can be used sporadically. ” "For example" "For example, all kinds of training courses, small tables, small classes.
There are also some state-owned factories that are dying of life, and I have seen them when I was handling cases before, and there are still bulletin boards in the factories.
There are also a few small street shops, especially restaurants, you must have seen it, with a small blackboard at the door with information about today's specials.
But the most noteworthy thing is, of course, the school. ” Wu Duan thought for a moment and said, "You can first send someone to the school in Mocheng to conduct a carpet investigation to see if there are any male teachers and staff in their 50s who are missing." ” "Then I'll add another worldly restriction to you," Mink Fang said, "This is also the second thing I want to say: judging from the number of low-temperature resistant microbial colonies on the fingers and meat slices, the deceased was frozen for at least 8 months. ” "What" "It's been too long to speculate on the exact world, but 8 months can't be wrong It's February 2019, and if you push it forward 8 months, it's July 2018, the height of summer.
The deceased was killed last summer, and judging by the degree of decomposition, the body should have been cryopreserved immediately after the killing.
For 8 months, the killer has been slowly cutting and discarding the body, which is really "It's very" Mink Fang looked for the right adjective, "What a chronic child." ” Wu Duan concluded: "So, we are looking for a man in his fifties who disappeared last summer and is on the fat side.
He had access to chalk and had calluses on his hands from long hours of writing, probably a school teacher.
At the same time, judging by the nail trimming, he has good hygiene habits and has also been to the nail salon" Wu Duan shook his head, "I always feel a little torn." ” He decided not to dwell on the issue in the autopsy room, which was beyond the scope of the medical examiner's help.
As Wu Duan was talking, a forensic assistant entered the room and handed two pieces of A4 paper to Mink Fang.
Mink Fang thanked him, looked down at the content on the paper for a while, and after Wu Duan finished speaking, he continued: "The information on blood tests and DNA tests has come back.
There should be no criminal record, at least there is no match in the national DNA database.
Blood tests showed that the deceased had blood type O and high blood lipids.
Beyond that" Mink Fang reconfirmed the contents of the report, "Other than that, there is no representative information." ” Wu Duan took the report, "Okay, I'll sift people first." ” Wu Duan walked quickly out of the autopsy room and returned to the office of the first team.
As soon as he entered the door, he clapped his hands a few times, "There is a job, a few brothers" Several criminal investigation team leaders gathered around, and Wu Duan arranged: "Xiaoxiao is responsible for screening missing persons, and I will send you the screening conditions later." ” "Okay."
"Xiao Lai and Liangzi are responsible for taking people to visit, and all the eligible people screened out by Xiaoxiao must understand the clear and detailed information as soon as possible, and make a list of eligible people."
"Okay."
"Lao Wei, your people go to contact the industry association in the city, I remember that there is a beauty industry association in Mocheng, and many chain store owners who can't do nail art are in that association.
Go ask them for help, send the news to the nail salon industry group, in short, try to spread the news as quickly as possible.
Ask if you have received any eligible male customers, and I will send you the screening information later.
After all, there are only a few men who go to nail art, and if they have received it, they should be more impressed. ” "Okay," Lao Wei said, "Then I'll take someone to the industry association first." ” Wu Duan called the name of a team leader again, "Sift through the report records of various sub-bureaus and police stations, since the murderer cut people into small slices and discarded them, maybe he has also received relevant reports."
If we can find other places where the body was dumped, we may be able to locate the range of the murderer. ” Wu Duan was a little hesitant to say the words "place where the corpse was thrown", because strictly speaking, what was thrown away was no longer a "corpse", but just some scraps.
"Okay."
The team leader asked, "Do you want to adjust the surveillance?"
Wu Duan shook his head, as if he remembered something, and did not reply, but said first: "I'll take a look at the cleaner's interrogation record." ” Lao Wei handed over a notebook, "Here, if this is not detailed enough, I will transfer the law enforcement recorder for you." ” "No," Wu Duan said, "The cleaner said that in the past, there was a cleaning truck in charge of dumping the garbage can every day, and it was the same yesterday."
Today's snow clearing task is relatively heavy, and the cleaning vehicles have been photographed on the main road to transport snow, and they can't take care of the garbage cans, so they will be dumped by hand. ” "Yes.
We went to the sanitation company to get the cleaning truck driver to inquire, and according to the driver's recollection, yesterday he dumped the garbage cans on the target street in the afternoon."
"Are you sure in the afternoon?"
Wu Duan said.
"The driver is sure."

Wu Duan glanced at the close-up photo of the bottom of the trash can again, and said firmly: "The severed finger and the meat slices were thrown in by the murderer after the trash can was dumped yesterday."
When the time frame is determined, you can adjust the monitoring of the intersection, and the pedestrians and vehicles passing by during this time will be screened.
There are also people who have been in and out of the surrounding community, and the community monitoring is also adjusted. ” A criminal police team leader who was not assigned a task took the initiative to say: "Then let's go, transfer back to monitor us and the detective, and the speed can be faster." ” "Okay."
A criminal police team leader who had not yet figured out Wu Duan's train of thought asked, "This can determine the time."
"Do you feel that today's road is particularly slippery?"
Wu Duan asked.
The criminal police team leader nodded, "Slippery, I almost slipped when I went out in the morning." ” "That's right.
Because there is ice.
In the past, there was only snow when it snowed, but today it is different, and there is a thin layer of ice under the snow.
Because the temperature warmed up two days ago, the previous snow melted, and the road surface was basically wet, and in some places it was very muddy.
Yesterday at noon, the temperature had reached above zero, and when the sanitation truck went to collect the garbage, even if there was ice at the bottom of the bucket, it should melt, and the fingers and meat slices were frozen at the bottom of the garbage can, and they should be able to be dumped out with other garbage.
The fingers and slices of meat we see could only have been thrown into the trash after they were dumped in the trash yesterday afternoon and before the cleaners found them today. ”:
