In the surveillance footage, the little boy He Mingxuan suddenly returned home after going out for ten minutes, and suddenly had a nail gun in his hand that children could not reach at all.

Moreover, he aimed the muzzle of the nail gun directly at the woman sitting at the cashier at the door, that is, his biological mother.

The little boy didn't give anyone time to react at all, and without saying a word, he pulled the trigger directly, and shot his mother directly with a nail gun at a distance of less than three meters.

The mother didn't even have time to react, and before she even let out a cry, she was pierced through the heart by a nail and lay on the table and died.

Immediately afterwards, the little boy walked very calmly towards the commissary.

Since there is no monitoring facility installed in the commissary, we have not seen the footage of the murderer killing. However, judging from the situation on the scene, we already know what happened.

That is, the little boy shot his father who had just come out of the toilet with a nail gun.

Finally, the boy walked out of the store very calmly, his nail gun well hidden by the pumpkin cloak.

The little boy killed two people in a row, from entering the gate to start the crime, to leaving the gate after completing the crime, the whole process did not even reach half a minute.

The little boy's purpose is very clear, that is, to enter the house and kill people.

He killed two people in a row, and all of them were shot with precision aimed at the heart......

It's hard to imagine why a five-year-old boy would kill his biological parents, and what made him commit such a rebellious murder.

Although the surveillance video let us know the complete process of the case, at the same time, it also gave birth to a lot of questions in our minds-

First of all, there is the question of the murder weapon, how did this little boy get the nail gun that can kill people? And how do you accomplish a precise shot aimed at the heart?

Secondly, there is the issue of the identity of the murderer, in the surveillance screen, the murderer and the little boy He Mingxuan are dressed exactly the same, but he is wearing a pumpkin doll hood, we cannot confirm the true identity of the murderer. If the murderer deliberately wore the same costume as the little boy He Mingxuan, so as to make the two deceased let their guard down and kill him by surprise, then the murderer must have carefully planned and deliberately chose to kill on the night of Halloween.

Third, there is the issue of the motive for the killing, the murderer killed two people in a row in less than half a minute and then left, which shows that the murderer's purpose is very clear, that is, to kill people and kill people, which is a very typical vendetta.

Fourth, it is a problem of modus operandi, when the murderer entered and exited the gate of the crime scene, he did not use his hands to open the door, but leaned his body against the door and opened the door with the help of his body. Therefore, he did not leave any fingerprints at the scene. A child would never have such an anti-reconnaissance consciousness, nor would he kill so calmly, let alone shoot accurately. And from the time he entered the gate to commit the crime, to the time he left the gate after the crime, he behaved very calmly without the slightest panic.

Although there are many doubts in this case, there is at least one conclusion that we all agree with -

That is the murderer in the surveillance video, although it is exactly the same as the little boy He Mingxuan's dress, but under the huge pumpkin doll hood, it will definitely not be the little boy He Mingxuan.

This is really a terrifying thing to think about, and I can't help but think of a horror story:

[You'll always check the candy in your child's hand after "trick-or-treating.]

But it never occurred to you to examine the child under the mask. 】

"Whoever is under that pumpkin hood, at least one thing we know for sure is the height of the murderer. It's just that the footprints at the scene are very complicated, and the trace examination department is carefully investigating and comparing many footprints, but it will take a lot of time to screen out the footprints of the murderer. Jiang Tingbai frowned, because the scene of the crime was a small store, and there were a lot of people coming and going every day, and there were a lot of footprints left.

"The murderer is not very tall, and he is about one meter and two by eye." Xue Hang pondered for a while, and suddenly said.

"Children are not mentally mature, and it is difficult to complete a case of killing two people in a row, killing them in one blow without leaving any fingerprints." Li Meng muttered softly, and then she blinked, and according to the current situation in the hands of the police, she gave a profile of her crime-

"The murderer is a man with a legitimate job, and he should run some small businesses on his own to make ends meet. The murderer suffers from dwarfism, which makes him feel very inferior, he is especially concerned about what others think of his height, this long-term inferiority complex can easily lead to his psychological deformity, once someone points at his height, he will have hatred, so as to complete the vendetta. ”

"Therefore, as long as we look for dwarfism patients who match the criminal profile throughout the city, especially through the hospital's medical records, we will definitely be able to find the murderer!" Lin Zifan said excitedly.

After all, with the key clue of dwarfism, the investigation of the case seems to be much easier.

But Li Meng shook his head, saying that he couldn't put all his hopes of finding the murderer on the hospital.

Because dwarfism is divided into two types, one is congenital and the other is acquired.

"Congenital factors refer to heredity and are caused by inherited genes, that is, chromosomal abnormalities.

If the parents have dwarfism, then the child born is likely to also have dwarfism, which is also called familial short stature and primary dwarfism.

This form of dwarfism is caused by a chromosomal abnormality and is an incurable form of dwarfism.

Acquired factors refer to the lack of growth hormone secretion, especially pituitary dwarfism, if the pituitary gland secretion of growth hormone is insufficient, it will lead to short stature in children, pituitary dwarfism generally in the early stage of the disease will appear growth retardation, with the continuous development of the disease, the average height of the patient will be lower than that of peers.

Relatively speaking, the latter's dwarfism will occur in the case that the parents do not have any dwarfism disease, in the face of this dwarfism, the patient will choose to seek medical attention, as long as it is controlled and treated in time, under the guidance of the doctor, some growth hormone is appropriately supplemented, and at the same time eat more high-protein foods in daily life, which can promote bone development and complete the cure of dwarfism. ”

After listening to Li Meng, it is true that the way to arrest the suspect cannot be all staked on the hospital's medical records, and even if the murderer has gone to the hospital for treatment, he may not necessarily be treated by the city's hospital.

Still, we have a way to do it......
