This is the strangest murder scene I've ever seen.

Since I became a police officer, I have entered the scene of a crime countless times, and I have seen all the bloody scenes, and it is the first time I have seen such a beautiful crime scene.

The deceased seemed to be asleep, and the rose petals in the room brought her into a dream world filled with the scent of roses......

The technical team was still investigating the scene in the room where the crime occurred, and forensic doctor Ren Qiushi and forensic assistant Zeng Lan had already come to the bedside to prepare for a preliminary autopsy at the scene.

To be honest, the woman's appearance, combined with this kind of dress in the room, is simply so beautiful, I really can't bear to spoil this beautiful picture.

It's just that the woman is the deceased in this case, and the room is the scene of the crime in this case.

"The corpse temperature is still there, the corpse mortis is not fully formed, and the time of death is within two hours." Ren Qiushi gently raised the woman's slender hand and said seriously.

"The deceased was serene, there was no pain, there were no signs of a fight at the scene, and the deceased's clothes were intact and free of wrinkles. It should have been an acquaintance who committed the crime, and it was a sudden death. Zeng Lan said in a deep voice.

Ren Qiushi shook his head slowly, and said lightly: "You can't judge from these, this crime scene has been carefully arranged, the traces of the fight and the folds of the clothes can be artificially erased, and even the deceased's outfit may have been worn by the murderer for her." ”

Ren Qiushi paused and continued: "The forensic doctor should not only look for clues from the crime scene, but more importantly, look for clues from the corpse itself, the corpse can't speak, let alone deceive. ”

"Hmm." Zeng Lan nodded.

Ren Qiushi carefully examined the body surface of the corpse, judging from the expression of the deceased, it was indeed possible that he died suddenly, and there was no blood at the scene, so the cause of death became particularly important.

"The wrists and ankles are common parts of restraint and resistance injuries, but there were no obvious injuries on the deceased's body, let alone fatal injuries. It is very likely that the deceased died from internal injuries or some kind of sudden illness. Ren Qiushi said lightly and went around to the head of the deceased.

Ren Qiushi gently lifted the deceased's head, and suddenly stopped the movement in his hand.

Because he felt a strong bone friction sensation, the feeling of the fractured ends rubbing against each other was very obvious, and it was accompanied by a distinct bone friction sound.

In this way, the cause of death is very obvious, the deceased died of cervical vertebra rupture and dislocation.

However, there was no obvious trauma to the deceased's neck, indicating that the deceased's cervical vertebrae fracture was not caused by a violent impact.

"The deceased had his neck broken." Ren Qiushi slowly lowered the deceased's head and said in a deep voice.

"Broken neck?"

Zeng Lan frowned suddenly, very surprised by this.

Cervical spine misalignment, fractures, and fractures do lead to death, but this type of trauma is more common in violence, such as car accidents, high falls, and heavy falls.

This kind of violence will have obvious external injuries, but the deceased did not, and the deceased died suddenly, which means that someone suddenly used force to break her neck while she was not looking.

"This is a martial arts master." Zeng Lan subconsciously muttered.

The killing method of twisting the neck is mostly seen in film and television works, and the martial arts masters in it often use this trick, or hand-to-hand combat, or sneak attack, or assassination. Moreover, this method of killing has become a common means for special services and agents.

However, this situation only exists in film and television works, and it is almost impossible to accomplish in real life.

Unless the other party has absolute strength and professional training in killing skills.

"Although the human spine is the weakest and deadliest place, it is also the best protected place. The murderer did not use brute force, but skill, and the murderer must have been professionally trained in this area and knew the human skeleton very well. Only in this way can we take advantage of their unpreparedness and kill them with one blow. Ren Qiushi looked at the corpse in front of him and made a somewhat incredible sound.

The main principle of the so-called broken neck leading to death is that after the neck is broken, it will lead to fracture of the cervical vertebrae or joint dislocation, which will then lead to spinal cord injury or transection in the spinal canal.

The entire spine of the human body has 24 vertebrae, plus a sacrum and a coccyx. Among them, the thickest ligament is the most strongly connected to the lumbar spine, which is basically indestructible by hand.

However, the cervical spine is different, with two more lethal vertebrae.

One section is called the atlas vertebrae, and this vertebra is particularly small and has a tooth process depression, which is particularly prone to injury.

The atlantovertebra is located in the posterior artery of the lower cerebellum, and the arteries of the nervous system are very fragile, and if the vertebrae are injured, it is easy to cause artery rupture and hemorrhage and death.

One section is called the pivotal vertebrae and has a very pronounced odontoid process. If the atlantovertebrae are subjected to a strong impact, the odontoid process is likely to break or break directly and insert into the spinal cord.

Nerve artery rupture, spinal cord injury, any of these conditions are very fatal to the human body.

In the process of development and evolution, the human body naturally knows that it is very weak, so it will protect it.

Therefore, it is absolutely impossible to inflict this kind of trauma, both in angle and in force, without special training.

And the murderer is fatal with one blow, which also shows that the murderer is completely sure and believes that he has absolute ability.

"This time, we've got a professional killer." Ren Qiushi sighed.

"Professional killer?" After listening to the analysis of the causes of death of Ren Qiushi and Zeng Lan, I felt a little shocked.

I turned around and asked Xue Hang beside me, "Can you break someone's neck with your bare hands?" ”

Xue Hang thought for a while: "I can't, because I haven't received special training. However, in the special operations units of the armed police, this kind of killing skill is completely achievable after special training. ”

"Armed police special operations, that's an active military unit. When a soldier goes to the battlefield to kill the enemy, he must use killing skills. I nodded and muttered.

Ren Qiushi turned around and also asked Xue Hang a question: "Apart from the army, is there any other profession that can have this kind of killing technique?" ”

Xue Hang looked at Ren Qiushi in a daze, and said in a cold voice: "I can't think of any profession that can master killing skills for the time being, but this kind of killing skills is not about strength, but about skills." Strength can be practiced by anyone, but skills are not mastered by everyone, the murderer must understand the structure of human bones, and accurately grasp the distribution of bones. ”

Xue Hang paused, and added: "Even if you have strength and theoretical knowledge, you must go through long-term training, because only in this way can you not be inferior in action." ”

"It seems that our opponent this time is not simple." I felt an inexplicable sense of oppression.
