Forensic pursuit

On the 28th of the twelfth lunar month, it will be Lunar New Year's Eve in two days. The police would rather catch two more thieves than run into a criminal homicide, let alone a case where it is still impossible to accurately determine the time of death.

At 12:30 in the evening, the on-site investigation ended, and the meeting room of the Criminal Investigation Brigade in the complex building of Nanyun District was surrounded by the main officers of the first investigation team.Everyone looked solemn, as if they were waiting for Chu Wanning to speak.

Sitting on the stage, Chu Wanning stared at the screen in front of her, browsing through the photos taken on the spot, without saying a word.

After a long time, she closed her laptop and raised her head to deploy: "Xiaoliang and Xiaochen, investigate the missing persons in the past year and determine the identity of the deceased as soon as possible. Fanxin will continue to follow up the autopsy and trace examination. Others, visit the neighborhood where the crime occurred. Residents, ask if any suspicious persons or suspicious signs have been found in the past ten months."

Xiaoliang was skeptical: "Captain Chu, after ten months, if there is any suspicious person, they must have forgotten about it long ago."

Chu Wanning got out of the wooden chair and stood up: "That depends on whether the impression is deep or not. The information has been deeply processed and retained in the mind for a long time, so it is not easy to forget."

Chen Anyou patted Xiaoliang on the shoulder, and explained: "Brother Liang, Team Chu will teach us about psychology. If you don't understand, just do the work."

Xiaoliang was a little annoyed: "Who said I don't understand? I just forgot, forgot."

Chu Wanning interrupted the two and seemed to have the idea to continue talking: "It's very late, everyone go home to rest, work overtime tomorrow Saturday, try to solve the case as soon as possible, and go home for the New Year with peace of mind."

"Captain Chu is wise." Chen Anyou cheered, and whispered to Xiao Liang next to him, "I thought it was another night, but she finally knows how to be considerate of her subordinates."

Xiaoliang retorted: "Isn't Team Zhou the same before? I think you are prejudiced. Team Chu's pressure is greater than ours, and I haven't seen her lose her temper."

Chen Anyou and Xiaoliang walked outside the door and lowered their voices: "Are you looking for Team Chu?"

"Don't just know about love and love all day long. Team Chu is the object of my admiration. I heard that many records of Yuanzhou Criminal Police Academy are still kept by her, and no one can break it."

Chen Anyou clicked his tongue: "I don't like women who are too strong, including Sister Xin. Today, the scene of the case did not change."

"Isn't Wan Forensic Physician more powerful? Just touch it with your hands."

"It's different. Forensic Doctor Wan has a soft heart, but it's a pity that he has bad eyesight and didn't like me."

Xiaoliang has nothing to say...

Nie Fanxin didn't say a word from the beginning to the end, packed up the materials, and just left the seat on the front foot, Chu Wanning called her back: "Fanxin, wait for me."

"Yeah." Nie Fanxin stopped and stayed where he was.

Chu Wanning turned off the lights in the conference room, walked towards her, and asked, "Are you going to the research institute?"

Nie Fanxin was still thinking about their interaction at the scene of the crime, and her words were unusually plain: "Yes, I understand the progress of the autopsy and wait for her to get off work."

Chu Wanning closed the door and said casually, "I'll go with you."

Nie Fanxin's tone became even lighter: "Then I won't go, take her home early."

Chu Wanning seemed to be aware of her emotions, and her voice was soft: "Fanxin, why do you feel that something is wrong during this time?"

Is it too obvious?Nie Fan frowned inadvertently, paused for a few seconds, and finally pulled a smile from the corner of her mouth: "Sister Wan Ning, it's an illusion, maybe you are too busy." She lowered her eyes, adjusted a little, and said again, "I'm worried that no one will see her off. Go home, but with you here, why worry?"

Chu Wanning always felt that there was something in Nie Fan's heart, but she couldn't figure out what it was, so she replied: "You and Xiao Yu are on the way, I have to go home and feed the cat."

Nie Fanxin was a little surprised: "Cat? Don't you think it's troublesome to shovel shit?" When the university picked up a stray cat, he wanted to ask Chu Wanning to take care of it, but was politely refused.

Chu Wanning raised the corners of her lips visibly with the naked eye: "At this time and at that time, my friend's cat is very cute and is fostered at my house."

"Do you have any photos? Let me see." Hearing what the other party said, Nie Fan became inexplicably interested.She likes cats, but it's a pity that Gu Bei is slightly allergic to cat fur, so she never kept them.

"A little tangerine called pea." The two chatted as they walked, unknowingly arrived at the downstairs of the research institute, and then went upstairs together.There was no one in the general dissection room on the third floor. Just about to make a call to inquire, I happened to meet Wei Lan, the assistant who was going downstairs to get things.Wei Lan reminded them: "Captain Chu, Officer Nie, you need to change into protective clothing when you enter the corruption anatomy room."

Nie Fanxin smelled the stench coming from her body, and asked, "Is the smell particularly strong?"

Wei Lan pinched her nose and fanned the air around her: "Well, you can smell it when you wear a mask and protective mask."

Chu Wanning didn't say much, and asked directly: "Where is the protective clothing?"

"In the dressing room at the end of the corridor, there are still five or six sets in the last locker. You can wear them according to your own size. I will go up to help first." After finishing speaking, he ran up without looking back.

The two put the protective clothing on the outside of the clothes, took the mask, mask and gloves, and then went upstairs one after the other.Before entering the dissecting room, standing by the door could smell the stench in the air.Nie Fanxin took a deep breath, stood under the disinfectant spray, and then paced inside.

Wan Yi is signaling to the video staff to pay attention: "The right heart, liver, kidney and other internal organs are congested, and the groove in the neck is in the shape of a horizontal ring closure. The groove can be partially interrupted, and the end is not obvious."

Wei Lan, who was in charge of recording, asked without hesitation, "Strangled?"

Wan Yi responded: "Well, there is no phenomenon of the sloping and interrupting of the gutter, which is strangled. The knot is pressed on the back of the neck, and a small amount of tissue remains inside the nails. It should be that the murderer strangled the deceased from behind. The deceased struggled and scratched the murderer. "

Chu Wanning asked based on experience: "Is there any murderer's blood?"

Wan Yi walked to the pathology collection table behind her, and said back to her: "The deceased should not have much strength, so there are few remaining tissues, and the possibility of testing another individual's genes is small."

Nie Fan was concerned about the baby who was less than 50 centimeters tall lying next to the female corpse: "What about the baby? Did it die after birth, or before birth?"

Wan Yi focused on the movements of her hands, and Wei Lan explained: "Officer Nie, forensic doctor Wan will do a lung float test right away to check whether the fetus died before birth or after birth."

"lungfloattest is the lung float test." Wan Yi took the lungs taken from the baby's chest and put them in the water, and saw the dark lungs floating up quickly.She closed her eyes and opened them again, as if sighing softly, and finally concluded: "The fetus died after birth, the cause of death was entanglement of the umbilical cord, resulting in mechanical asphyxiation."

Nie Fanxin looked at the photos earlier and recalled the details: "Why did the umbilical cord separate from the mother's placenta? Did someone cut it?"

Wan Yi motioned Wei Lan to show them the photo: "The cross section is neat, it should be cut by the murderer with scissors."

Nie Fan's eyes darkened: "What kind of mentality does the murderer have? Why did he cut the umbilical cord?"

Chu Wanning rubbed the center of her brows: "Maybe it's to see the fetus is uncomfortable and help him out, maybe it's just a subconscious behavior without any reason."

"As for the cut in the neck, look." Wan Yi washed her hands, picked up the remote control and scrolled down, "The severed part is well organized, knowing where to cut it is easy to separate the head and neck, which means that the murderer should undergo medical surgery for a long time, or Do forensic work like I do."

Chu Wanning stared at the screen intently, and asked, "What about ordinary doctors? Isn't clinical medical anatomy compulsory?"

"No, I can't do it without rich practical experience." Wan Yi put away the remote control, went back to the sink to wash and disinfect her hands, took off her mask and mask, turned her back to them, and began to breathe heavily and urgently.

Long hours of fully armed dissection and lack of enough oxygen are unbearable for ordinary people, let alone her.The stench was poured into the nose instantly, Wan Yi raised her hand to cover it lightly, turned and walked out of the dissecting room.

"Light rain."

"Sister." Chu Wanning and Nie Fanxin called her nervously at the same time.Seeing Chu Wanning following up, Nie Fanxin hesitantly took back the steps she had already taken...
