The murder weapon used by the murderer was a nail gun that could not be accessed by a child. And judging from the fact that the murderer completed the crime, he also has a psychological quality that a child cannot have.

As a result, the police directly ruled out the possibility of a child committing the crime, so the murderer is likely to be a dwarfism patient.

"The clothes of the murderer when he committed the crime are exactly the same as the deceased's five-year-old son, He Mingxuan, and we can investigate from the sales channels of the clothing." I thought about it for a moment and said slowly.

"There are also nail guns used by the murderer, which can also be investigated from the sales channel." I added one more sentence.

Xue Hang didn't speak, he carefully looked at the murderer's nail gun through the images in the surveillance video.

"The gun is modified." He suddenly spoke, and said lightly.

"The murderer will also be modified?" I was very surprised, and hurriedly walked to Xue Hang's side, Xue Hang pointed to the nail gun in the surveillance, and explained to me the modification process of the murderer.

Xue Hang, an expert in using guns, knows a lot about firearms, and he said a lot of professional terms when he explained to me, in short, it is a sentence, the murderer carried out a gunpowder brake transformation for the nail gun, so that the initial speed of the nail firing is faster and the lethality is greater.

Since the murderer can have the ability to transform firearms, this is even more certain that the person under the pumpkin doll's hood is definitely not a child, but a relatively short adult.

Since everyone has the same idea, the next case investigation work will start from four aspects.

First: Throughout the city, look for dwarfism patients who match the characteristics of the murderer.

Second: Find ways to buy Halloween pumpkin doll costumes worn by the murderer.

Third: investigate the purchase method of the nail gun used by the murderer, the nail gun is a special manual equipment for construction and construction, because of its huge lethality, so when buying through formal channels, you often have to show your own qualifications, and you can buy it only if you are qualified.

Fourth: Investigate the social relationships of the two deceased to see if they have any enemies, especially if they have had contact with a person with dwarfism in their lives.

Fifth: Retrieve the surveillance video of the commissary, extend the viewing content to a month, and see if any patients with dwarfism have ever entered the commissary to buy things and have a quarrel.

Sixth: Retrieve the recent travel routes of the two deceased to see if they have been in contact with any dwarfism patients, and the investigation time will be temporarily placed within a month.

In this case, we still have a lot of clues, so we don't have any pressure, on the contrary, we feel that this is a vendetta caused by the inferiority complex of a person with dwarfism.

I believe that in a few days, the murderer can be apprehended.

The Serious Crime Unit immediately contacted the Criminal Police Team to jointly investigate.

At dawn the next day, the serious crime team carried out the familiar separate operation, each investigating the direction for which they were responsible.

Li Meng and I are responsible for investigating the social relations of the two deceased, and the premise of investigating the social relationship is to first determine the identities of the two deceased.

The female deceased, named Li Xuemei, was 36 years old and a native of Ningzhou City.

The male deceased, named He Xiangshan, was 39 years old and a native of Ningzhou City.

I looked at the deceased information in my hand and fell into deep thought.

"What are you thinking?" Li Meng also leaned over to look at the information of the two deceased, and suddenly looked up and asked me.

I thought about it, didn't speak, and handed the deceased's information to Li Meng.

Li Meng also looked at it for a long time, and I asked her, "Did you find anything strange?" ”

Li Meng focused on the life history of the two of them, read it repeatedly, she shook her head with a frown, and replied to me: "Everything is normal, there is nothing strange." ”

As soon as she finished speaking, she suddenly asked me, "Have you found anything strange?" ”

I smiled and said to her, "The man is thirty-nine, the woman is thirty-six, and their son is only five. ”

After Li Meng listened to my words, he suddenly realized that "the time for them to give birth to a child is indeed too late, and getting old and having a child doesn't mean anything." ”

"I can't really say anything, I'm just curious. If He Mingxuan is their second child, there is nothing strange, but judging from the identity information of the two, they did not have children before. I said slowly.

After all, when two people want to have children, when to have children, and how many children they have, it is the freedom of others, and there is no strict standard, so it cannot be measured by the lifestyle of ordinary people.

I'm just curious.

"Have the parents of the two deceased been contacted? It is not a long-term solution for He Mingxuan to stay in the Public Security Bureau. I took a deep breath and suddenly asked.

"He Mingxuan's grandmother and grandfather went to the Northeast to see the snow with the tour group, his grandmother has passed away, and his grandfather can't be contacted for the time being." Li Meng earnestly briefed me on the investigation.

"Did you tell them about the deaths of Li Xuemei and He Xiangshan?" I looked at Li Meng and asked slowly.

Li Meng shook his head: "After all, the old man is old, and in order to prevent accidents, the colleague in charge of contact did not tell them the truth of the matter, but just used an excuse to tell them to return to Ningzhou City as soon as possible." ”

"On the one hand, the loss of parents at a young age, and on the other hand, the loss of children in old age are all tragedies of life." I let out a long sigh, secretly worried about them.

As a criminal policeman, I have seen too many life and death partings, and people often say that since the deceased has left, then the living person must carry the will of the deceased and work hard to continue to live.

But how can a living person not fall into deep thoughts?

But there is one thing I have not been able to investigate, that is, how did the two deceased come into contact with this murderer with dwarfism? How did they provoke the dwarfism murderer?

It seems that all of this will have to be answered through our investigation.

At this moment, a criminal police colleague who was in charge of contacting the family of the deceased sent us good news.

He Mingxuan's grandfather was contacted, and he lived in Ningzhou City.

After receiving the address sent to me by my criminal police colleague, Li Meng and I immediately drove to He Mingxuan's grandfather's house.

He Mingxuan's grandfather's family lived in the economic development zone of Ningzhou City, and the information shows that He Mingxuan's grandmother died seven years ago.

Knocking on the door of He Mingxuan's grandfather's house, it was a woman who opened the door.

This surprised us a little, and after confirming the house number repeatedly, I asked, "Is this Old Man He's house?" ”

The woman looked Li Meng and me up and down, a little displeased......
