Wu Works in the lab.
Wu Feng, 37, is a forensic doctor at the Institute of Forensic Science and Technology of the Yangpu Branch of the Shanghai Municipal Public Security Bureau, the mother of a 4-year-old girl and a graduate of the West China Medical Center of Sichuan University. For people who died unnaturally, Wu Feng was the one who gave them the last proof, and the person who looked for the answer from the corpse.
accidentally? commit suicide? homicide? Where there is contact, there must be traces, which is the foundation of forensic technology. "For example, if a person is stabbed several times, which knife is fatal, we solve this problem." "Without the ultimate cause of death, the evidence is incomplete." Wu Feng did not wear a police uniform, did not wear makeup, had his hair tied casually behind his head, and was not good at showing closeness when he saw people.
No one moved the body until the forensic doctor entered the scene. When Wu Fenggang was working, he went to a scene by the railway side. There is a deep green belt, green grass knee-high, usually rarely haunted. Flies, beetles, maggots have been "out of the grass", and deep in the green belt is a corpse.........
It was late at night when he came back from the scene, and Wu Feng was eating steamed buns while displaying pictures of the scene on the large screen of projection. Ling Wei, director of the Criminal Investigation Institute, was deeply impressed by that scene and lamented that the first female comrade in the institute was not ordinary.
There are also some scenes that are false alarms. Around Halloween, someone reported that there were blood-covered arms in the construction waste, and the forensic doctor arrived and found that it was a prop. There was also a drunk man lying in the house stripped naked, and the smell was unpleasant. Relatives thought he was dead, and when the forensic doctor arrived, it was said that all the shou clothes had been bought, which was later confirmed to be oolong.
Most forensic doctors have allergic rhinitis because the smell of hydrogen sulfide produced by corpses is very heavy, which stimulates people to tears. Wu Feng once held a case of hiding corpses in the closet. She and her colleagues went to the scene many times to look for key evidence, and had to do psychological construction before each trip. The crime occurred on the third floor, and she could smell it from the first floor.
The deceased and the suspect were a halfway couple who came to Shanghai from other places to rent a house. The rental house is five or six square meters, with a bed and a cabinet the size of a vending machine, and outside the house is a common kitchen.
The deceased's son found that the mother and the family only used WeChat for a long time to contact, always hanging up the phone or video. Suspicious, he came to Shanghai to find the landlord, and the locksmith opened the door and found that the wardrobe was completely sealed, nailed, and taped. Inside, in addition to the women's clothes hanging, there was a woven bag with a lot of cat litter pressed on it.
"We analyzed that this woman has been dead for half a year." The suspect and the deceased lived in the same environment, everything may have traces, how to prove that he did it? The police took evidence from the things in the house one by one and looked for clues.
A remnant of tape was eventually found, and the head of the newly torn tape was still attached to the cabinet. Together with the tape that sealed the cabinet, Wu Feng and his colleagues reduced it to a complete roll of tape through experiments, and found traces of the suspect on it. "This proves that he hid the body."
Wu Feng said that the case is not decided by isolated evidence, and the work of forensic doctors is to continuously strengthen the effectiveness of evidence.
What appears to the medical examiner is the scene after the fact, and what happened here at some time in the past needs to be reconstructed. It's a puzzle-solving journey, and it's the key to the career's appeal to Wu. There was once a deceased man with blood in his abdomen, but his internal organs were intact. Eventually, Wu Found an opening the size of a needle tip on a branch artery under the pelvic cavity. "The feeling that I finally found, often there is."
Details in the eyes of a forensic doctor can sometimes change the course of a case. One of the deceased fell in the bathroom with a knife edge on his body, and his girlfriend said that he slipped while taking a bath and was just poked by scissors and died.
Wu Feng looked at the corpse and found that unlike the scissor wound, if the scissors were open, there would not be only one wound, and if it was closed, the size of the wound would not be right. No traces of the deceased were found on the scissors. Eventually, the girlfriend admitted that it was the two of them arguing, and she took a knife from the kitchen and killed each other by mistake, causing death by negligence.
Every successful puzzle solving brings comfort, in the words of Wu Feng, "When the case in hand is handed over, it is like a daughter sent by an old father to marry." ”
After having a daughter, Wu Feng's work was a little farther away from the dissection table. She did physical evidence testing in the laboratory, but also followed by the analysis of the case, the other day, she received more than 60 test materials, wrote a 22-page appraisal.
Forensics is a combination of detective and science. Ling Wei, director of the Criminal Science Institute, introduced that the Yangpu District Criminal Investigation Institute was established in the 1980s, formerly known as the technical group, there are 6 people, and the most used is a flashlight and a small brush. In 1995, it was upgraded to a technical room with 10 people, and by 2003, the technical strength gradually appeared, expanding to the current 25 civilian police. In addition to conventional physical evidence, we are also exploring the collection of voiceprints and irises.
Wu Feng's dream when he was a child was to be a scientist, and he wanted to study medicine in high school, but he felt that the clinic was too bitter, "There are endless people in Shanghai University Hospital" and "the risk of cutting live people is much higher than cutting dead people.". The college entrance examination volunteered to apply for forensic science at Sichuan University, and her mother was so angry that she lay in bed for a week.
There are two periods in her life where she takes pleasure in pure learning, one is junior high school and the other is college. "Every lesson is an eye-opener".
One of the hardest things about studying medicine is pathology. The only time Wu Feng stayed up all night when he was in college was the eve of the pathology exam, "The knowledge points are vast, and any chapter can produce thousands of multiple choice questions." Before reviewing, I thought I could get 80 points, but it was enough to change to 70 points on the eve of the exam. In the middle of the night, she thought she would just pass. Walking into the examination room, "as long as the test is finished, you will be relieved." It wasn't until I got the paper and glanced at it and saw the title of the meeting that I had "that feeling when dawn came" was born.
In the anatomy class, the teacher pointed to the "general teacher" and said, "Why do you hate him and think he is dirty?" He's been soaking in formalin for so long, much cleaner than you guys, he doesn't even have bacteria. ”
Wu Feng returned to Shanghai after graduating from undergraduate and was admitted to the Shanghai Public Security College, which is the local police recruitment system, similar to the civil service examination, the academic system is one and a half years, and most of the time is interned within the public security, which is equivalent to pre-job training.
There were various versions of textbooks in her office, flipping through them from time to time. Outside the office is a laboratory, with lights and instruments forming a bright white space, a pot of plants placed on the ground, and overhead lights simulating lighting. The artificial environment makes people lose the concept of time, here is Wu Feng's refuge, "I can be quiet alone, the test materials handled in my hand have standardized procedures, unlike going to the scene, ever-changing, people are in a state of stress." ”
Colleague Zhu Wenkai, the youngest forensic doctor in the firm, said that Wu Feng liked "1 + 1 = 2" things. The quality of the experiment has three states of red, yellow and green, generally yellow can be, she must be green. Another female teacher who did physical evidence, Jin Yi, mentioned her, and the first word that came to her mind was "safe", "She feels that she will definitely not go wrong here, and it is worth trusting." ”
Wu Feng does not like to change, it is best to have a schedule accurate to the minute every day, just click this. "I'm essentially a rigid person who wants everything to be in its grid."
She doesn't like complicated narratives, including famous books, "In fact, that is the literary foundation of others, but the words I usually use are crisp and precise." Professions such as lawyers and teachers make her feel "very tired and have to fight with people."
In a way, the pressure to face a corpse is much less than facing a family member. Looking directly into someone's eyes can sometimes feel oppressive, and the eyes of the deceased have no eyes, "and they will not feel that he is looking at you".
"I can make decisions and be myself on the spot, but in the face of others, I am not alone. In the past, we were often criticized by the leaders and would only talk to the dead. "They specially designed a notice sheet in the institute, which is partly instead of communicating with the family.
Talking about the process of biological research, you will unconsciously become excited, "E. coli is a good employee of the world, don't want you to give overtime pay, you split, split, split."
Before Wu Feng gave birth to her daughter, there was a walled fish tank in the house, which had been raised with aquatic grass, and she would adjust the pH value and light, and inject carbon dioxide into it. She has loved natural science since she was a child, "forensic medicine is mainly medicine, but there is also entomology, botany, you have to be a miscellaneous family." 」 ”
In life, she has no reasoning, no terror, rejecting everything that needs to burn her brain. "I used to think jurassic park was scary."
Work needs to be calm, and the teacher said that if you worry too much, you will not be able to get down. "Your purpose is to find the cause of death. Focus on your puzzles, too emotional can interfere with judgment. ”
When the forensic doctor is long, the social reality seen is far more complicated than the dissection of the corpse. The elderly living alone are a common disease in big cities, "the neighborhood committee pays attention to the elderly, but there will still be a vacuum, and sometimes people die for more than a month before they are discovered." ”
What Wu Feng despised most was the death of the child. "Adolescent children have a very strong temper, and in the past two years, they have often committed suicide because of conflicts between playing mobile phones and parents."
There is also the passion for killings caused by social hostility, and Wu Said that such suspects always regret it. There were two people in the unit who did not deal with it, one stabbed the other, jumped into the river by himself, and the next day the person who was stabbed lived, and the person who stabbed him died.
Accustomed to seeing corpses, Wu Feng was more free to death than his peers. After she got married, she registered her body donation, and her husband said that she was excessive, "and she didn't want to bury it with me when she died." She said, "Maybe you can donate too."
When she went to college to face the "general teacher", she decided to donate her body. "Our family is very materialistic." Her hometown is in Chongming, and in the past, when Qingming went back to the grave to take a boat, Shanghai was often foggy, and she couldn't leave for the dock several times.
"My dad likes flowers, and he said that if he didn't pick a pot and bury him underneath, he could just take it out and worship him."
When Wu Feng was in college, she joked with her classmates, "I don't know which medical school I will be in after I die," and they laughed at her, "How do you know that you are the whole child." Ordinary people may find this a huge offense, "Only a forensic doctor can make such a joke, the first two weeks sent a medical report, they directly said your autopsy report is coming."
"Everyone knows that there are many tragedies in work, but we try to downplay the sad part because it's already our lives."
The first two sentences of the medical school oath are related to health and life, and Wu Feng said that health and forensic medicine are irrelevant, "but life is entrusted to us." ”
Flaws refer to spots on jade, and Wu Feng was born with a birthmark on the back of his hand, which his parents took advantage of. Later, she took the lancet and the reagent bottle in both hands, and spoke for the dead, so as to bless the living and make justice flawless.
