Criminal Minds Profile 2

Song Yucheng's clear and cold voice fell, and everyone's face was covered with a layer of gloom that was difficult to dispel.

Everyone thought of the unsolved case that had not yet been solved. The young male corpse floating in the water was missing two kidneys.

The last time it was the kidney, this time it was the liver and gallbladder. What exactly did the murderer want to do?

"Heart, spleen, lung and kidney, the murderer must have collected five internal organs..." Xiao Chen muttered in a low voice.

"Don't talk nonsense!" Tao Ranjin scolded, "The most taboo is preconceptions when investigating a case. We haven't even finished investigating the scene, and the corpse has not been autopsyed. What the same murderer did will mislead everyone."

However, Tao Ranjin's words did not dispel the fear and suspicion in everyone's hearts.

Although Xiao Chen's words were hasty and abrupt, they just expressed everyone's aspirations.

On September [-]th, a young male body was found in the banyan forest on the back mountain of Kailing University of Technology. The first person to find the body was the school ranger. After the school verified the identity of the deceased, the deceased was the chairman of the student union of the School of Public Administration. Zhang Mingchen.

The deceased was suspended from the branches of a [-]-meter-high banyan tree, facing due east.The hanging rope consists of two pieces, the upper part is the hemp rope, the lower part is the twisted hair of the deceased, and the middle part is connected by a water knot.

The deceased was wearing a dark green silk shirt. The shirt was torn by a sharp object, then torn into several strips and hung on the deceased's shoulders.The lower body of the deceased was completely naked, and the black trousers and underwear were scattered aside, which were also cut into two pieces by a sharp object.

Several bloodstains were extracted from the leaves of the banyan tree and the soil under the body of the deceased. After inspection, it was found that they belonged to the deceased himself.No suspicious footprints, fingerprints or DNA traces were extracted at the scene.

Autopsy examination: the deceased was male, 23 years old, 185 cm tall and 75 kg in weight.Congestion and ecchymosis were seen on the scalp of the corpse.The frontalis muscle is raised, the eyeball protrudes from the orbit, and the upper and lower eyelids are exposed.Punctate hemorrhage of double eyelids and bulbar conjunctiva, exposed sclera, cloudy and liquefied cornea.Take the vitreous humor and see bloody turbidity.The hepatic artery and vein were severed, the liver and gallbladder were missing, and no obvious abnormalities were found in other organs.There were strangle marks on the wrists and ankles of the deceased, and a small defect in the epithelium of the skin, on which adhesive tape remained.

It was determined that the cause of death was hemorrhagic shock caused by abdominal sharp instrument injury. According to the test of the stomach contents of the deceased, it was speculated that the time of death was between [-] am and [-] am on September [-]th.

After Song Yucheng reported the situation of the body examination without emotion, he sat down silently.

Diao Shuzhen stared at the autopsy report in his hand in a daze, not knowing what thoughts were running in his little head.

"Come on, let's talk." Tao Ranjin put down the autopsy report that seemed to weigh more than a thousand gold, and glanced at everyone in the task force, "There is another case, do you have any ideas?"

The atmosphere fell silent like death. Everyone stared at the files in their hands, frowning, with ugly faces, and said nothing.Some people reached into their pockets and wanted to take out a cigarette to light it up to relieve the suffocating pressure, but Song Yucheng gave him a slap in the face, and put it back embarrassingly.

"I'll say it first." Diao Shuzhen raised his hand and said in an official tone, "In my opinion, the method of this case is extremely cruel and the nature is extremely bad. Social ethics, the murderer must be arrested and brought to justice as soon as possible, and justice must be given to the deceased!"

You leave this as Qingyun!

"Listen to what you have to say." Tao Ranjin couldn't help laughing, and bent the corner of his mouth, "It's like listening to what you say."

After Diao Shuzhen's interruption, the suffocating and dull atmosphere in the conference room dissipated a lot invisibly, and it no longer pressed on people's chest like a thick cement board.

Speaking of which, both Diao Shuzhen and Song Yucheng are very human beings - after a crime happened, they stared at the case file and wandered away, without any dignified expression, as if they were playing a suspenseful reasoning game.

Facing the horrific death and the loss of organs again, the other body showed no emotional fluctuations, and gave a professional autopsy report like a robot.

Since the "Oriental Campus Banyan Grove Murder Case", the fearful rain has shrouded everyone's head, and it can be said that people are in panic.After all, although Kailing's economy is underdeveloped, it has always existed like a paradise. When did such a vicious incident happen?

This is like a place where the seasons are as warm as spring, where the tender flowers and grasses have sprouted, and suddenly a hailstorm hits the head and face, and everyone is as big as an egg, so who can withstand it?

"Since I asked the question, I'll use it as an example, let's talk about it first." Tao Ranjin glanced gratefully at Diao Shuzhen, who raised his eyebrows casually.

She drew a diagram of the technical university on the whiteboard.

"We have found the taxi driver who took Zhang Mingchen back to school that day, and proved that he got off at the west gate of the school. The dormitory of the School of Public Administration is on the east side of the school." Tao Ranjin drew an arrow and continued, " And when Zhang Mingchen returns to the dormitory from the gate, he must pass through the half-moon-shaped Little Mirror Lake. The murderer ambushed him here."

"Because the autopsy did not reveal Zhang Mingchen's craniocerebral injury. Although Zhang Mingchen was drunk, the murderer was able to subdue a young, tall young man in a short period of time, probably with the help of some kind of fast-evaporating anesthetic." Speaking of this, Tao Ranjin glanced at Song Yucheng.

"It may be diethyl ether, which is generally used in surgical operations. It can make people unconscious within 50 seconds." Song Yucheng continued, "If it is indoors, you can consider extracting the air in the room, and then use gas chromatography [1], an ultra-trace amount of ether can be detected. However, Xiaojing Lake is a place open to convection, and it has been 24 hours since the incident, so it cannot be extracted.”

"Well, there is another question, that is, after the murderer ambushed the deceased, how did he transport the deceased to the killing point, which is the center of the banyan forest, without leaving any footprints?" Tao Ranjin threw out the first Two questions, "The route leading to the banyan forest is roughly divided into three sections. The first section is the outermost, a cement path about 30 cm wide, with pebbles fixed on both sides. It is about 200 meters long. The second section is pure trees. Roots and soil, no trace of repair."

"The third section is the center of the banyan forest. The branches and leaves here are much thinner, the sunlight is abundant, and weeds are full."

"Because the banyan trees have luxuriant branches and leaves, most of the sunlight is blocked, and the air humidity inside is high. Most of the road surface in the second section is moss and other moss plants, and occasionally there are a few low shrubs."

"This section is about 30 meters long. On the soft and slippery ground, how did the murderer transport Zhang Mingchen, who weighed 150 kilograms, without leaving his own footprints?"

After the initial fear and shock, in Tao Ranjin's step-by-step analysis, everyone's strong negative emotions dissipated a lot, and they really began to shift their attention to solving the case.

"The murderer must have worn shoe covers." Xiao Chen said, "On a solid road, you can not leave your own footprints. But how do you do this on a muddy ground?"

"Look carefully." Tao Ranjin released a video. The camera was above her head, showing how she walked through the woods from the first perspective.

"The murderer stepped on the root of the banyan tree!" Xiao Liu patted his head and suddenly realized.

"This has a relatively accurate range for the murderer's height, weight, and athletic ability." Tao Ranjin concluded.

"But, the murderer is not only going through the mud himself, but also taking the unconscious Zhang Mingchen with him?" Diao Shuzhen, who had wandered to the centaur constellation, came back to his senses and asked with great interest, "Zhang Mingchen alone has to weigh 150 catties. , plus the murderer's own weight, more than 200 catties can walk back and forth on the slippery and uneven roots of the banyan tree? How can there be a martial arts master in modern society."

She has a strong mind and no scum in combat, and she has a limped leg so she has to be careful not to damage the scene of the crime.If Song Yucheng hadn't grabbed her by the collar in time, she would have kissed the earth several times.

It's a deep resentment.

"You got the point." Tao Ranjin patted the table and laughed, "Who said the murderer entered with Zhang Mingchen on his back? He used a zipline!"

"Zipline?" Diao Shuzhen rolled his eyes and came to his senses.

"Look at this picture." Tao Ranjin took the picture on the whiteboard and said quickly, "I was thinking about this question the first time I saw the corpse dumping site."

Those were two partial microscopic images of bark with obvious signs of damage and a fresh pothole.

"The murderer first fixed the nails on the outer trees, and then fixed the same nails on the trees inside. The height difference between the two is about half a meter." Tao Ranjin drew a sketch and continued. , "Then pull a load-bearing steel wire between the two, and fix Zhang Mingchen with a knot. Due to the effect of gravity, he will naturally slide to the other end."

exquisite.

Such a word crossed Diao Shuzhen's mind.

From the ambush to control the victim, the method of killing, the place where the body was dumped, and the cleaning up and disposal after the event, every link was planned so meticulously that it could be said to be seamless.

Diao Shuzhen bent his mouth, and a cold light flashed in his amber eyes.

Such a murderer, in the first case, would leave a sliver to the police that almost said who I am?

A king's player, would he make such a bronze-level mistake?

"The forensic examination and the inference of trace science are only here for the time being. We have roughly restored the incident of this case." Tao Ranjin said, "The murderer ambushed the drunk Zhang Mingchen by the Xiaojing Lake and used anesthetics to make him unconscious. Then transport it to the center of the banyan forest, kill the people to harvest the organs, and then hang the body on the branches."

"Then, there are still some key issues that have not been resolved. That is, whether this case can be investigated together with the Fengbo Hotel case, which is also a case of harvesting organs after murder?"

"At the scene of the crime, why was the deceased disheveled? Why did the murderer deliberately hang the deceased on a tree? Why did they harvest their organs? What kind of behavior pattern did they follow?"

After Tao Ranjin finished speaking, he turned his attention to Diao Shuzhen who was doing nothing.
