Criminal Minds Profile

Diao Shuzhen opened her eyes, the sky was already bright, she raised her hand to cover her forehead, the dazzling light made her pupils shrink slightly, and it took a while to get used to it.

She wiped the cold sweat off her head indiscriminately, feeling a sense of weakness all over her body.Not far away, after taking pictures of the scene and examining the traces, Song Yucheng was conducting an autopsy on the deceased, and another forensic doctor from City C was taking notes beside him.During working hours, the bridge was filled with dense traffic, which was so crowded.Annoyed people honked their horns, and the piercing whistle sounded one after another.

It was a sunny day, and through the reeds by the river, the river surface was locked in a layer of thick fog, making it difficult to see clearly.

It seemed like an ordinary morning.

Diao Shuzhen sat down, his eyes became clear and sharp again.It had been a long time since she had been involved in the emotional torrent of a murder scene like this without warning.But she knows why.

The scene was shrouded in a suffocating fear and despair. The thick black was like black snakes, curled up and wandered on the ground, and covered every inch of space within a radius of ten meters centered on the corpse. .The chill of fear was still running through the scene, trying to penetrate her skin and flow along the spine to the brain center.

The hairs all over Diao Shuzhen's body stood up.

As a criminal psychology profiler, Diao Shuzhen has seen countless bloody and cruel scenes, many of which were skinned or amputated, and even killed alive.She has experienced the fear and despair of countless people.

However, she has only seen such pure fear in two places, the site of the Nanjing Massacre, and the Auschwitz concentration camp.

It is conceivable that the elderly are definitely not as simple as being strangled to death or drowning.

Song Yucheng came back, and she called Diao Shuzhen who was in a daze.There was a relieved expression on her face, a strand of black hair stuck to her pale face, the whiter the whiter, the blacker the black, showing her cool temperament.

Seeing that Diao Shuzhen's expression was not very good, she handed her a gel pen and nodded.

Diao Shuzhen grinned and raised his eyebrows.

"Don't underestimate me." Diao Shuzhen wrote the victim's cause of death on the palm of his left hand, and Song Yucheng lowered his head, which was also a normal gesture.

The two spread their hands, a line of block letters neatly lined up in Song Yucheng's white palm, the words were "mechanical suffocation caused by mud and sand clogging the mouth and nose", while Diao Shuzhen had two words written on his hand, Scribbled and unrestrained is "buried alive".

The two looked at each other and smiled.Diao Shuzhen suddenly felt that the fear in his heart had dissipated a lot. Looking up, the sun penetrated the clouds and shone down.

It's sunny.

"Let's go, there's still a project meeting in the afternoon." Song Yucheng stretched out his hand to give Diao Shuzhen a hand, "Don't sit on the ground, be careful not to catch a cold."

On April 4, the Municipal Bureau of City C received a report.The deceased Sun Fengdi, 12 years old, was from Luogang District, C City.I usually live alone at home, and my son and daughter-in-law are doing retail business in other places.The grandson, Sun Qian, is a sophomore in Hongshan District, C City.

After the preliminary investigation of the scene and the forensic examination, the deceased's mouth was stuffed with a sock, which was worn by the deceased's left foot.It is known from the inside of its nose and dissected airway that the deceased died of mechanical asphyxiation caused by swallowing sludge.3000 yuan in cash wrapped in a plastic envelope was found inside the deceased's clothes.Due to the sudden drop in temperature in City C on the night of the incident, it can only be preliminarily estimated that the time of death of the deceased was between 11:1 last night and [-]:[-] am.

The forensic autopsy report is as follows: the deceased was fully clothed, his face was bruised, and his mouth was stuffed with clothes.The syringa of the face is not closed, and sediment can be seen under the palpebral conjunctiva.Skin contusions were seen on the right shoulder blade.The lips are flattened and dirt is visible in the external nose. CNM stale crack, GM has shit.There was soil in the pharynx and larynx, and the skull was uninjured.The cause of death was mechanical asphyxia caused by chest and abdomen compression caused by soil burial and airway blockage.

Judging from the discovery of nasal mucosa, glottis, larynx and pulmonary edema of the deceased, respiratory failure caused by a large number of foreign bodies entering the airway, and tearing bleeding from the ventilator group, the deceased was conscious when he was buried and did not take medicine. She has been given tranquilizers, and she has no craniocerebral injury caused by external forces. She has struggled fiercely, and even begged the murderer to let her go.

In other words, the dead were buried alive!

To a seventy-year-old man, the method is so cruel and the nature is so bad.

Song Yucheng's clear and cold voice echoed in the meeting room, and everyone felt a great pressure.

Diao Shuzhen lowered his head and fell into deep thought.If we talk about the method of burial alive, it usually only occurs in war massacres, or in the feudal era, in order to establish their authority, the rulers intimidated a certain group, such as burning books and burying scholars.

However, in modern society, even if Diao Shuzhen reads the history of crimes extensively, it is used as a means of committing crimes.Those who would adopt such cruel methods are either minors with immature minds and bad natures, or the inadvertent mistakes made by patients with mental disorders.

It is quite rare to really use burial alive as a means of killing people.

Greater doubts lingered in everyone's minds. What kind of motive did the murderer use to kill an old man who had no resistance in such a primitive and cruel way?

According to the call records of the deceased, he received a call from an unknown number at 21:34 last night.Then, with the testimony of a taxi driver, the deceased took a taxi to the scene of the crime.At about 10:30, Sun Fengdi arrived at the scenic belt along the river.According to the taxi driver, the old man Sun Fengdi had a phone call with her son in the car at that time, to the effect that her grandson, Sun Qian, had a car accident by the river, and the old man took the only 3000 yuan left at home and rushed to the river. scenery belt.The son of the deceased asked the old man to deal with the affairs here first, and rushed back from the field by himself on the plane that night.

Based on the signs of the corpse and the circumstances of the case, Song Yucheng speculated that the murderer used Sun Qian's car accident as an excuse to trick the old man into rushing to the scene of the crime, subdued the old man at the scene, and finally dug a pit to bury him alive.

The police established the following investigation ideas.[-]. Search for the source of evidence within the city, mainly the source of the red glass rope.

Second, find the owner of the phone number and the source of the calling card.

[-]. Focus on investigating the social relations of the deceased, especially those who have entanglements with the deceased and their families.

At the project meeting, everyone sat around the long table, frowning, staring at the file, looking preoccupied.

Diao Shuzhen smiled wryly, knowing that this kind of investigative thinking was tantamount to finding a needle in a haystack.

First, the murderer should be a person with an extremely meticulous mind and a strong sense of anti-reconnaissance.And it is definitely not for money, or for mental disorders, to kill unintentionally.Not to mention the heavy rain last night, even the sunny and dry weather may not be able to leave many traces.

Second, the red glass ropes used to bind the deceased are common items, and are sold in major supermarkets and retail stores in this city.Not to mention the channel of online shopping.Diao Shuzhen just searched for the same type of rope, and the store with the most sales has sales of tens of thousands of copies every month.In fact, it is impossible to accurately find the source of the rope.

As for the knotting method, in Diao Shuzhen’s impression, it does not seem to belong to any method of revealing the murderer’s identity, such as the basic knot of weaving, surgical knot, sailor’s knot, or climber’s Bollinger knot or reversed figure-of-eight knot. Nor does it look like a jacquard pattern or part of a traditional Chinese knot.The murderer tied the knot in order to achieve the purpose of binding.As for that phone number, since the murderer dared to use it, he would definitely not leave any traces.

Third, it seems that we can only hope to get some clues from the investigation of the deceased's social relations.

Diao Shuzhen frowned more and more.She couldn't be more optimistic about this.

Hatred.

The intense hatred left at the murder scene is far from being caused by ordinary daily economic disputes and quarrels about trivial matters in neighborhood life.If the murderer is not mentally impaired, then what is the reason why the murderer hates a [-]-year-old man in his dying years so much?

The conference room suddenly fell silent.Diao Shuzhen belatedly realized that all eyes were on him.

Director Chang of Room C asked again patiently, "Xiao Diao, what do you think of the murderer?"

It turned out that I was too absorbed in my thoughts just now, and didn't hear the director's question.She felt a little sorry, and said slowly, "This is my portrait of the murderer."

She hooked up her computer screen to a projector and projected it onto a white wall.
