Forensic pursuit

The criminal police can accumulate common sense in forensic medicine and trace inspection in handling cases. Chen Anyou was right, there were indeed no threatening injuries, restraint injuries or resistance injuries found on the deceased.Nie Fanxin's idea of ​​guessing the identity of the deceased from the details is also beyond doubt.

As soon as the man finished speaking, everyone involuntarily looked towards the source of the voice.In the field of vision, the half-squatting figure on the right side of the corpse slowly straightened up and stabilized for two seconds before turning around.She is tall and outstanding, her shoulder-length hair is half-tied, and she is wearing a blue suit. As she walks this way, she takes off the sterile gloves and mask she is wearing. She seems to be throwing them into the garbage without any mistakes. Temporary accumulation area.

The woman was none other than Nie Fanxin's non-blood cousin Wan Yi.Nie Fanxin originally thought that the other party was in the same situation as her own, that Wan Tong or Nie Zhiyan had conceived in October through a scientific method, but it was only later that she became an adult and found out that Wan Yi was the child of Wan Tong's eldest cousin's second aunt's daughter.Because of a car accident and dystocia, both parents died, Wan Tong took her here to raise her, even her household registration is far away in Shanghai, and she has not yet gone through the adoption procedures.Wan Tong found it troublesome on the one hand, and thought it was just a formality on the other, so he only signed Zhang's guardian's certificate.The elders didn't hide Wan Yi's secrets, they would take her to Shanghai to visit her surviving grandmother every holiday and visit her parents' graves.

Closer to home, under the sun, Wan Yi's delicate face seemed to be covered with a layer of sickly white, her thin red lips opened and closed, her speech was slower than that of ordinary people, but it sounded reasonable and loud.

"The body surface of the deceased is complete, there is no external injury on the body, and the corpse spots are dark red. First, freezing to death, and mechanical asphyxiation such as strangulation are excluded. Secondary corpse spots appear on the limbs and chest respectively, indicating that someone has moved the corpse significantly, so this is not the place. The first crime scene."

Excluding freezing to death, plus denying the crime scene, it can basically be confirmed as a murder and dumping the body. Chen Anyou, who has been stable for more than half a year, did not shed tears when he saw the coffin, and asked in a low voice: "Forensic doctor Wan, why did you rule out freezing to death?"

The person he called Wan Forensic Doctor took up the conversation and responded to his doubts: "The spots on the frozen dead corpses are bright red, the rigors develop late, disappear slowly, and are tough. There should be traces of frostbite on the body surface, such as blisters, but the body of the deceased None of them match."

"Understood now, thank you Wan Forensic Doctor." Chen Anyou smirked at her twice, and called Xiao Liang to work, "Captain Chu, please rest assured to leave the verification of the identity of the deceased to us, and we promise to finish it within two hours."

Although she was suspected of talking big when she heard it, Chu Wanning still nodded.She waited for the two to walk away, and squeezed her eyebrows that had just been loosened, and asked worriedly: "Xiaoyu, based on your experience, what might be the cause of death?" The investigation team of the Brigade has worked for 7 years. Three years ago, it was separated from the criminal investigation due to special tasks. Therefore, it has participated in no more than seven major homicide cases, and almost all of them were successfully solved in prime time.But her intuition told her that this case was extraordinary, and the murderer's anti-detection ability was extremely strong.

Wan Yi shook her head: "An autopsy is needed to find out, it's a bit tricky." She called Chu Wanning and Nie Fanxin to go over and observe, and the three stood on the left side of the corpse, "Excluding death from freezing, electrocution, and mechanical suffocation, only from pathology and poison Reasonable analysis, if not, it is suppressed death."

Nie Fanxin conditioned reflex and said: "Suppress death? A slight external force caused cardiac arrest?"

Wan Yi nodded slightly, affirming her statement.

"Then take the corpse back first." Chu Wanning stretched out her right hand, palm down, and looked to the left and right respectively, "The police have applied to the research institute to assist in the investigation and handling of the case. Next, we will cooperate happily."

Nie Fanxin and Wan Yi said in unison: "It's a happy cooperation."

The warm sun was in the sky, and the gentle wind mixed with the fresh smell of the soil after the rain hit the broken hair by the ears of the three of them.Their palms and backs of their hands were touching, and they met for the first time three years later, as before, they were still familiar with each other.

In the office of the Criminal Investigation Brigade in Nanyun District, most of the colleagues in the whole group were on the go, including Nie Fanxin among the sporadic three or four people.Her gaze is parallel to the computer, and she browses the page ten lines at a time while typing.

A message reminder suddenly popped up on the WeChat computer terminal.

Wan Xiaoyu: "Come over and watch the on-site autopsy?"

Nie Fanxin bent her lips and tapped the keyboard quickly: "Come on, come on, who is afraid of whom?"

"Change in the locker room on the second floor, see you in the first general anatomy room on the third floor."

Nie Fanxin's task happened to be to keep abreast of the progress of forensic medicine and trace inspection, so she sent a message to Chu Wanning who was in a meeting, and got permission to pack up the materials on the table and prepare to leave.As soon as he raised his head, he bumped into Chen Anyou's courteous face. The people in front of him laughed until their facial features crowded together: "Sister Xin, do me a favor."

"Don't, don't call me that." Nie Fan felt disgusted, and his expression was full of disgust.

Chen Anyou coughed lightly, and pretended to say: "Comrade Xiao Nie, the time has come to test our revolutionary friendship. In line with Marxism..."

Nie Fanxin followed him and said, "Old Comrade Chen, can you directly pick the key points?"

The smile on Chen Anyou's face increased a bit: "Cough, help send flowers to Forensic Doctor Wan, I don't have time."

The person sitting did not hesitate at all, and blurted out: "Yes."

"Really? I'll do it another day." Chen Anyou took out a car key from his trouser pocket and put it on Nie Fanxin's desk, not forgetting the mother-in-law's advice, "The flowers are in the trunk. Remember to remind Wan Forensic Doctor that I am busy with work. Otherwise, I will definitely give it to her in person.”

As soon as he finished speaking, someone urged him in the corridor, and he said before leaving: "You guessed right, the deceased is Lu Zhenglin, a third-grade math teacher at Yonghe Road Private Primary School and a counselor for the Young Pioneers. vice-principal."

"Family reported missing?"

"Colleagues from the school informed Lu Zhenglin's wife that he didn't go to school to attend the flag-raising ceremony this morning, and he chose to call the police when he couldn't get through at 8:50." Chen Anyou raised his eyebrows. Worry."

"Xiao Chen, Team Chu is looking for you." Someone shouted outside again, and Chen Anyou responded with a roar, and hurried out of the office.

Across the street from Nanyun District, the Judicial Research Institute has only two buildings. From the outside, the architectural history is not long. Twelve years ago, the Forensic Medicine Department of the Municipal Public Security Bureau and the School of Forensic Medicine of Binnan University jointly established a research institute to undertake basic research in the field of judicial identification; judicial identification and technical guidance of major criminal cases in the city; training of high-end talents in judicial identification and other functions .Nie Zhiyan, as the former Chief of the Forensic Medicine Department of the Municipal Bureau, was directly evaluated as the first batch of researchers of the Institute and enjoyed the state allowance.

In the second year after returning to China, Wan Yi became an assistant researcher and studied under Nie Zhiyan.At this time, she put on a disposable dissection suit, put on shoe covers, a surgical cap and a mask, and finally put on goggles.When you go out, turn left and go upstairs, pass by the Forensic Clinical Research Office, and the stainless steel door next door opens automatically.

She stepped onto the antiseptic floor in front of the dissecting table, and bowed reverently to the dead.

"Autopsy No. 2049, 28, Binnan City Research Institute, Lu Zhenglin, male, 28 years old, was dissected by assistant researcher Wan Yi, research intern Wei Lan recorded, and the video began." Wan Yi finished speaking and sat gently in the corner The woman nodded in greeting. The man wore glasses and looked dignified, but he couldn't hide the kindness in his eyes.

At this time, Nie Fanxin was also fully dressed, came in with a notebook in her hand, and quietly stood opposite the dissecting table.

"Scalpel." A round-edged scalpel cuts the skin, Wan Yi is not in a hurry, and in a clear manner, peeling and picking apart a small area of ​​skin, blood vessels, and nerves in reverse to avoid damage to important deep structures.

Time passed by minute by minute.

"Surgical forceps." Holding the tissue to be removed, she cut off the cartilage in the chest along the line drawn by her eyes, and then cooperated with the rongeur to complete the chest opening.

Nie Fanxin had watched Nie Zhiyan's dissection before, and this was the first time she had really watched Wan Yi from the sidelines.Her cousin, who looks weak on the outside, actually has a heart of perseverance that even her cousin can't measure.

Suddenly, he saw God.

"The heart and lungs and other organs are normal, and pathological causes have been ruled out to cause sudden death." After a long time, Wan Yi put the heart into the sterilization tray, looked at the corpse and fell into deep thought.

"Xiao Yu, when the body was found, what was the anal temperature?"

"32.1°."

The person who raised the question was Wan Yi's master and adoptive mother Nie Zhiyan. She continued to instruct: "Analyze the time of death."

"According to the outdoor ambient temperature, combined with rain factors, and when the body was found, the body surface was not covered, it is estimated that the time of death was from 0:1 am to 3:5 am at the earliest, and from 2030:0.5 am to 1:[-] am at the latest." In [-], the South began For heating, if the deceased is indoors first, the rectal temperature will drop by about [-]° per hour over time, and about [-]° per hour when the corpse is thrown outside.

Nie Zhiyan then asked, "The corpse was transported back to the research institute at 10 o'clock. Are there any new corpse spots?"

"No, the corpse spots have spread, so the time of Lu Zhenglin's death was between 0:1 and 4:[-] in the morning, and the body was thrown outside around [-]:[-]."

Nie Fanxin listened to the questions and answers of the mother and daughter, carefully recording the key points.Since the cause of death cannot be clarified, we should start with the time and investigate the family and social relationships of the deceased before his death.

After the first autopsy was over, Wan Yi took blood from the deceased and sent it to the Forensic Toxicology Laboratory for testing. She took off her gloves, with a faint smile on her lips: "Fan Xin, now I should know what Lao Wan said in the morning. What is the surprise?"
