An hour later.
In the anatomy lab, a team of young couples are crying bitterly, crying out to the sky.
The daughter who had just passed two months of her birthday disappeared, and then learned that she was killed, and she died so miserably, as parents, naturally their hearts and livers were broken.
Finally calmed their emotions a little, Yuan Youchong and Yu Chen immediately hardened their hearts and asked.
The details of her daughter's disappearance were made clear when she reported the crime, and after a month, it was impossible to add anything.
To sum it up in one sentence, when buying groceries, the mother and the vendor negotiated the price, paid the money, and when they turned around, the child was gone, leaving only a stroller.
Yu Chen and Yuan Youchong focused on asking them if they had a grudge with anyone recently, but unfortunately, they didn't ask any results.
Father Feng Linhao is an ordinary teacher, and he has a good relationship with his colleagues, and he doesn't have much contact with his parents.
Her mother, Lin Yun, is a freelance makeup artist, who freely undertakes local beauty and nail lists online, mainly helping newlyweds with makeup.
Overall, the social and interpersonal relationships between the two are quite simple, although there are some friends, but most of them are just superficial brothers and plastic girlfriends It's for them to hold back a few, but it's just trivial things, and they haven't even torn the superficial relationship, let alone killed people for revenge.
More importantly, they don't know Dai Sheng, let alone Dai Sheng's "friend" Duan Zheng.
No, Yu Yuan and the others had no choice but to settle them first, and promised to notify them as soon as the case was solved.
"It seems that we have to check the interpersonal relationship between Feng Linhao and his wife and Dai Sheng and Duan Zheng."
Yuan Youchong proposed: "If you know and get acquainted with this team of couples, and you also have dealings with Dai Sheng or Duan Zheng, the key investigation is the key one." ” Feng Lin frowned: "Didn't Feng Linhao and his wife not know Dai Sheng and Duan Zheng at all?"
"I don't know each other's friends with my friends, isn't it weird" Yuan You glanced at Yu Chen: "Don't say anything else, a few of my classmates who played well in junior high and high school, do you know or, if I play games, the friends I make in games, you know" "Got it."
Yu Chen suddenly realized and said, "Then I'll arrange someone to investigate." ” "Not only must we investigate, but we must also focus on investigation, and this is the only breakthrough in this case at present."
"Yes."
Yu Chen nodded, picked up the walkie-talkie, and arranged the task.
Then, he asked: "That courier brother" "Let's put it first, it's unlikely that he changed the suitcase."
Yuan Youchong waved his hand: "Just send two people to keep an eye on it." and the person in charge of sorting and security checks, he has Lao Wang's people staring at him, so we don't have to worry about it. ” Yu Chen snorted, and wondered again: "What do you say is the nature of this case, the murderer killed people, violated the mouth of the dead baby, dissected the corpse, and dried it, and after half a month, he planted the blame on Dai Sheng."
"If it is just to deal with the corpse, it should be more reliable than planting the blame, pulling it to the deep mountains and old forests or throwing the corpses into the river, and pulling it to the Fujiang River to go to the Shenjiang River."
"You know, don't look at the many corpses we salvaged from the Fujiang River this year, but the Fujiang River basin is so long and the river is so wide, God knows how many dead souls are in it" "Don't worry about these things yet."
Yuan Youchong waved his hand and said, "Find out the murderer, everything will naturally be clear." ” Yu Chen couldn't help but hey: "Isn't it also to find out the murderer's thoughts to shorten the investigation area?"
"But there are too few clues, and you can only guess without any basis, which is meaningless."
Yuan Youchong waved his hand: "If you really want to have a heart, it is better to start with the murderer's modus operandi." ” "Mo-Opera" "For example, a certain volume of food, fruit and vegetable dryers."
Yuan Youchong said: "This thing is quite niche, ordinary families will not prepare it, even if there is, the volume is not large, it is okay to get a small amount of dried fruits and dried meat, and it is not enough to completely dry the corpse of a dead baby." ” Yu Chen thought for a moment and asked, "Then, will the murderer work in this kind of food factory, with the help of the equipment in the factory?"
"No, it won't."
Yuan Youchong shook his head: "Have you carefully read Xiao Zhou's autopsy report, what do you think she used to infer that Feng Kangying has been dead for about half a month to a month?"
Seeing Yu Chen's bewildered look, Yuan Youchong sighed, shook his head and said: "If you want to air dry quickly, it's very simple, just add heat, blood pressure, and air volume, the fastest, even half a day to a day, can air dry the body of a dead baby to this extent." ” "However, too high a temperature and too low a pressure can leave quite obvious marks on the corpse.
Xiao Zhou's report explained in detail that the temperature exceeds forty-seven degrees, and after a long time of drying, there will be burn marks on the skin, reaching fifty degrees, and the traces are even more obvious, more than sixty degrees, which can be seen at a glance. ” "However, Xiao Zhouzai carefully checked the corpse surface, investigated the moisture rate and trace elements, and even some large number of indicators that I can't even memorize, and finally determined that the temperature of drying the corpse is about 4344 degrees, the pressure is not less than 08 atmospheres, and the air flow rate is not higher than 8 meters per second."
In other words, it is dried for a long period of time in an environment close to the extreme of nature, which takes about one to two weeks.
According to the composition and content of trace elements such as microorganisms and dust on the corpse, it is speculated that one to two weeks have passed from the time it was dried to the time of the crime, and then it was determined that half a month to a month had passed since the victim's death. ” After speaking, he took a sip of hot tea to moisten his throat, and saw that Yu Chen still looked confused, so he couldn't help but pat his forehead and said: "A complete baby corpse, thrown into the factory equipment to dry for a week or two, what is the probability of being found and exposed, and his brain will be kicked by you?"
"Not to mention, the temperature, pressure, wind speed and other indicators of drying corpses are very different from the environmental indicators set by other dried foods, if he really uses the equipment in the factory to do this, let alone a week or two, he can't last half a day, and he will definitely be discovered."
"So, there is no doubt that the murderer did the process of drying the body at home.
Undoubtedly, this is an important indicator for us to further screen suspects. ” Yu Chen was still silent and frowned.
Yuan Youchong couldn't help but hey: "Old Yu, why did you talk about this today, you still can't figure out if it's too cold to freeze your brain."
"Tsk" Yu Chen finally responded, pouted and said: "I'm just thinking, since the act of drying the corpse is so obvious, how could he do this, besides, whether he wants to frame Dai Sheng and frame him, or simply blame for getting rid of the crime, it makes no sense to do this."
