Ren Qiushi opened the position of the back of the deceased's neck, and it was obvious that there were traces of cervical vertebrae dislocation and fractures, which was in line with the inference they had drawn at the scene of "twisted neck".

"Fractures of the atlas and axial vertebrae, resulting in the destruction of the medullary tissue, resulting in death on the spot, are typical of high cervical fractures." Ren Qiushi took a deep breath and said in a deep voice.

Immediately afterwards, Ren Qiushi confirmed the cause of death in detail: "The medulla oblongata is the center of life and the respiratory center, and once the bulbar is compressed, it will cause acute respiratory depression and respiratory failure, and it will cause acute cardiac arrest, and death by suffocation in a short period of time." The murderer's methods are very strong. Fast, accurate, ruthless, and lethal with one hit. ”

Zeng Lan looked at the exposed vertebrae and the obvious misalignment fracture, and gasped: "A high cervical vertebra fracture of this degree, even if you don't die, you will be paralyzed at a high level and completely lose your ability to take care of yourself." ”

Ren Qiushi nodded and said seriously: "That's right, this kind of high-level cervical vertebra fracture is the most common in car accidents, because of the sudden braking of the car, the human body is affected by inertia, and the cervical spine will be affected by a strong thrust in an instant, resulting in a dislocation fracture." But the deceased's body surface did not have any external injuries, not even bruises, and the murderer's methods were very professional, like a professional killer. ”

"I really can't believe that a man can break someone's neck with his bare hands." Zeng Lan sighed and took out the camera to take pictures and fix them.

Ren Qiushi calmed down, and after suturing the back of the deceased's neck, the two worked together to turn the body over for further autopsy.

Although a fracture of the high cervical vertebra has constituted an absolutely fatal injury, it cannot be ruled out that there were other causes of death for the deceased.

The deceased did not resist when his neck was broken, and theoretically, the deceased may have lost the ability to move and resist at that time. Therefore, a further autopsy is required to see if the deceased was at the onset of some sudden illness or whether the deceased had taken hallucinogens or toxic substances.

Any clue found through an autopsy may become the absolute key evidence in this case, and even have the possibility of overturning the case.

"Check the deceased's lower body, take a swab of the lower body, and see if she has had sex." Ren Qiushi said in a deep voice.

Gently holding the scalpel, he made a "slotted" incision from the neck to the abdomen of the deceased.

At the same time, the Serious Crime Team and the Criminal Police Team conducted a detailed investigation of Song Simeng's social relationships, including her family, colleagues, leaders, lovers, etc., hoping to find a breakthrough in it.

At the same time, the company where Song Simon works is also the top priority of the investigation.

With the crime profile and the evidence at the scene, we have grasped the main characteristics of the murderer, which has been of great help to our investigation.

On the other hand, the Technical Investigation Bureau is also carefully studying the recording of the informant, as well as investigating Song Simeng's private social software to look for clues.

The investigation of the case was in full swing, and it didn't take long for Song Simeng's parents, led by the criminal police, to enter the office of the serious crime team.

When the two old men learned that their daughter had been killed, they walked up to me, grabbed my hand, and said to me with tears in their eyes: "Comrade policeman, you must catch the murderer and avenge my daughter...... She was not yet thirty years old...... She's still young......"

Looking at the grief of the two old men, my heart is not good, but all I can do is to solve the case as soon as possible and catch the murderer.

"Don't worry, we'll catch the murderer." I swallowed hard, trying to make a sincere voice that reassured the two old men.

"Why do you want to hurt my daughter...... She's still so young......"

"Why...... Oh my daughter...... She's only thirty years old......"

In the office of the serious crime team, there were howls one after another, and the greatest sorrow in life was the departure of relatives, and the white-haired people sent the black-haired people.

I am not good with words, and I can't think of any words to comfort them. Maybe catching the murderer is the greatest comfort to them.

"Uncle and aunt, does Song Simeng have a boyfriend?" I made up my mind, arranged a seat for them, handed them tissues, and poured them a glass of water.

After hearing my question, the two of them looked at me, their bodies trembling and not making a sound.

"We initially suspect that this is a love killing......" Before I finished speaking, I heard my aunt suddenly make a high-pitched voice.

"It's him! It had to be him! ”

"Who?" I frowned and asked quickly.

"It must be him! That thing that took a thousand cuts! I'm going to cut him with a thousand knives! The uncle let out a grief-stricken roar.

The words of the two of them made me tense my nerves immediately: "Who is he you talking about?" ”

"His name is Fan Yuanzhong! It's my daughter's boyfriend! Auntie said through gritted teeth.

Fan Yuanzhong...... Boyfriend? What does he do? I immediately asked.

"He and my daughter were college classmates, and two months ago, this little bunny came to our house and had a big fight with us......"

Fan Yuanzhong and Song Simeng are the same age, their college classmates, Fan Yuanzhong is from the School of Physical Education, and Song Simeng is from the School of Economics. The two met at a sorority party in their sophomore year and have been in a relationship ever since.

After graduation, Song Simeng went to graduate school, and Fan Yuanzhong stayed in school as a wushu sanda teaching assistant because of his excellent grades, during which the two were divided and combined countless times. In the end, after the two completed their studies, they went to different jobs, and in a blink of an eye, they also reached the age of talking about marriage.

Just two months ago, Fan Yuanzhong and Song Simeng had a big quarrel. After Fan Yuanzhong got drunk, he came to Song Simeng's parents' house and had a big quarrel with Song Simeng's parents.

The reason is that Fan Yuanzhong found that Song Simeng and a senior executive and general manager of his company were very close and had a close relationship, which seemed to have surpassed the relationship between colleagues. Fan Yuanzhong asked Song Simeng for theories many times, but Song Simeng prevaricated, and in turn said that Fan Yuanzhong was careful.

It is not difficult to see from the description of Song Simeng's parents that after Fan Yuanzhong came to the door that night, he was very excited, and his words were very excessive, and the two sides almost started to fight.

Then Fan Yuanzhong slammed the door and left, and there was no more news.

Song Simeng's parents also talked to Song Simeng a few times, but Song Simeng didn't say anything, but just prevaricated with his own breakup with Fan Yuanzhong.

So Song Simeng's parents insisted that it was Fan Yuanzhong who took revenge and killed him.

This is definitely a major clue, Fan Yuanzhong is suspected of committing a major crime, and he is completely in line with our speculation about the suspect!
