Xu Zheng waited until the forensic doctors entered the scene, and took the initiative to go outside to intercept the curious crowd, at present, the situation is not able to say any news to the outside world, but unfortunately although he is very curious at this time, his task is to help the criminal police maintain the scene.

Waves of criminal police came and went, forensic doctors took away the bodies, and the physical evidence department collected footprints, handprints, and several liquids on the ground, including blood, and hair from all over the house.

At this time, the most devastating estimate at the scene was the old lady who called the police, Xu Zheng and Niu Panpan arrived first, and they appeased him for a while, and only when Anjou arrived did they record a confession for her, and Ji Meiyue continued to record a confession for her after she arrived.

Now waves of criminal police began to evacuate, this old lady actually said that she didn't dare to go home, because to go home, she had to pass by this security room, and the old lady still lived alone, so she had no choice but to use a police car to send the old lady to her son's house when they were evacuating.

It was already more than 1 o'clock at noon when he returned to the police station, and after eating in the station, Xu Zheng touched his mouth and ran out of the police station with his things, and he didn't sleep all night, staying up until noon, he didn't want any more emergencies for him to stay and continue to work.

When he got home, he came out after taking a shower and changing his clothes, Xu Zheng felt alive again, Han Xin hadn't gotten off work yet, and he didn't want to move, seeing that Han Xin's room was open, Xu Zheng wiped his hair and walked in.

I slept until more than 7 o'clock in the afternoon, and Xu Zheng, who came to life, walked out of the door and saw Han Xin who was busy in the kitchen, "Sister Xiaoxin, what do you do to eat at night?" It's so fragrant. ”

"I made your favorite duck soup, and I boiled it for more than an hour, and then I will start eating later." Han Xin saw Xu Zheng secretly pinching a piece of beef with his hand, and the corners of his mouth were crooked, "Go wash your hands first, by the way, I saw that your phone rang, it was Aunt An calling, I took it for you, I said you sleep, she said it's okay, hang up." ”

"Oh, then I'll give her a back in the past, I guess it's not a big deal."

When Xu Zheng called, it turned out that Anru was worried that Xu Zheng had forgotten the task assigned by the Wan detachment, so he specially reminded him.

Hanging up the phone, Xu Zheng scratched his head a little, this on-site investigation report is not easy to write, easy to write, but he can't write wonderful things now, at most it is similar to the report issued by the technical investigation colleagues of the detachment.

That's pretty much it, Xu Zheng feels bored writing this report, and it is estimated that the 10,000 detachments don't want to see the same report.

Then the problem comes, how to write this report?

Xu Zheng sat in front of the computer, fell into deep thought, and began to simulate the scene in his mind, and he reimagined the scene where the security guard attempted suicide and cut the artery with a watermelon knife.

He understood that this line of thinking must be wrong, otherwise the criminal police detachment would not have paid so much attention to it.

So it's not suicide, it's homicide, the criminal police detachment can pay so much attention, there must have been such a eucalyptus, is it a recent or a previous old eucalyptus?

It's a pity that there is too little information at hand to guess.

But what is certain is that the deceased must have been killed by him, and it is very likely to be a serial killing, so is this murder also a fake eucalyptus for the deceased to commit suicide?

Xu Zheng felt that it was wrong, if it was faked as suicide, wouldn't it be more like suicide if he was strangled directly with a rope?

According to the aunt who called the police, the security guard is about 70 years old, single, and has not been retired for a few years, and the pension alone is more than 8,000 yuan, plus the security guard is 1,800 a month, which is almost 10,000, and he is still single.

But the latest Apple mobile phone of the security guard at the scene is still at the scene, and the murderer of these 20,000 mobile phones has not moved, so it doesn't look like it's for money.

Is it possible that vendetta is possible?

Through the confession of the aunt who called the police, this doorman basically went home from work, he worked as a security guard in this community for more than three years, and he had never heard of him quarreling with the business.

has a good temper, has a stable life, and has not found other bad hobbies, besides, even if it is because of vendetta, it will not be enough to end it with one knife, there is no need to put so much thought into it.

But this vendetta is not impossible, maybe the enemy of the security guard when he was young, or he met a stranger on the street and made a feud at once.

Vendetta is not easy to guess, and it is not easy to investigate, if you check the life of the security guard for 70 years, no, 50 years, well, this is impossible.

Xu Zheng continued to think about another possibility, could it be love killing?

It's not that if you exclude all possibilities, the remaining impossibility is the only answer.

Well, this sentence means that Xu Zheng can't imagine how old the security guard's rival can be?

It's impossible for a 70-year-old to come in on a rainy night and murder his rival, right?

Although the security guard is 70 years old, about 165 tall and weighs more than 130 pounds, his body looks very tough, and his 70-year-old peers may not be stronger than him.

Is it possible that the security guard is not old and has found a little girlfriend for himself, by the way, this uncle seems to be surnamed Dong.

Xu Zheng shook his head and shook off this impossible idea, everyone is 70 years old...

Could it be a perverted killer who takes pleasure in killing and then uses it to play a game of cat and mouse with the police?

It's a pity that the evidence at hand is seriously insufficient, and these motive conjectures are untenable, Xu Zheng opened the mailbox, and without further pondering, he sent the suspicions and conjectures he found at the eucalyptus scene to the Wan detachment.

In the end, Xu Zheng described his murderous conjecture to the Wan detachment, on a rainy night, a man in a raincoat sneaked into the security room, found a rope from the security room, tied the knot, and put a handful on the neck of the sleeping security guard, tightened, after a few seconds, he felt that the uncle was not breathing, he let go of his hand, and the uncle touched the watermelon knife in the dark with his instinctive memory...

Xu Zheng felt that this was the most likely version, that is, he was not sure in terms of details, if it weren't for this method of killing, then this thing could not have been done by someone.

When Xu Zheng sent the email, the Wan detachment was in a meeting with the heavy eucalyptus brigade led by Qu Hou, and when he saw the email sent by Xu Zheng, he smiled, this conjecture was quite interesting, and then asked Qu Hou to take a look at it.

Qu Hou glanced at it, "I have seen the scene and can have this conjecture of the eucalyptus, but the motive he analyzed is a bit nonsense, we don't talk about killing for money and vendetta and perverted killing, I have thought about this for love, but I didn't dare to think about it on my little girlfriend."

But it can't be ruled out that this may not be, after all, there are no wonders in the world. ”

Qu Hou turned his head to look at Ji Meiyue and asked, "How are you doing in the village of 10,000 people with the neighbors of the deceased and his children?" ”

Ji Meiyue has been working in the Chongyu Brigade for 2 years, she is 26 years old this year, and she has solid work ability, she replied: "The residents of the 10,000-person village are not familiar with the deceased, especially the community where he worked as a security guard, the owner of the community nodded to him and said two words, saying that he had a gentle temper, and no matter how late he knocked on the door at night, the deceased would get up and open the door."

The deceased's family lived in the Yuehu Community, 500 meters south of the 10,000-person village, which is a well-known high-end community nearby, and the neighbors there are basically not familiar with him, but they have only met, and the security guards and doormen of the Yuehu Community are not familiar with the deceased, and they don't even know that the deceased was a security guard.

Also, by visiting the nearby entertainment facilities, no one there has ever seen the deceased go to them for consumption, so it can be said that there should be no problem in private life, and for so many years, the neighbors have never seen a woman go to the deceased's house.

At present, the two sons of the deceased are out of town, and we have informed them, and they do not know much about their father's situation, mainly because after the death of the deceased's wife, they have little contact with their sons, and they all live alone.

We also went to the place where the deceased worked before he retired, and many people there commented on the deceased as mild-tempered and basically did not have any conflicts with people. ”

Qu Hou frowned, looking at it this way, the motive of this eucalyptus is not easy to determine.

He thought for a moment and looked at the seven colleagues sitting there, "Let's get here today, let's go back early to rest and recuperate, this eucalyptus may be very difficult."

After you go back, consider whether there are any similarities between the three eucalyptus species that have happened so far, in addition to the eucalyptus technique.

There is no mistake

Think about it again, what other motives we didn't think of. ”

Xu Zhengke didn't know that there were the same three eucalyptus on the side of the criminal police detachment, and he didn't think about it anymore after sending the email, although he was very curious about this eucalyptus, but he knew that if he didn't have the value available, he couldn't be temporarily transferred to the detachment's heavy eucalyptus team.

"Xiaozheng, are you done? Hurry out and eat. Han Xin's meal was finally ready, and when he saw that Xu Zheng didn't come out, he had to come and knock on the door.

Maybe considering Xu Zheng's hard work on the night shift yesterday, today's dinner was very rich, Xu Zheng was really hungry, and after a while, he wiped out the three dishes and one soup made by Han Xin.

After eating, cleaning up, the two of them went out hand in hand, "Xiaozheng, a friend of mine wants to move over in a few days, oh, live opposite us, when you are free, come and help." ”

"Okay, just tell me in advance when the time comes, by the way, Sister Xiaoxin, is your friend a man or a woman?"

Han Xin glanced at him, "Of course it's a woman, and it's a big beauty, she is a Smecta person, she came to our school for 3 months, and she didn't want to live in the school's guest house, so I helped her find a house." ”

"Smecta people, Sister Xiaoxin, when did you learn Smectawen?"

"Hee-hee, you're not mistaken, we've always spoken English, but now we're learning from each other. By the way, Jin Shiya's makeup skills are amazing, let her teach you when the time comes. ”

Xu Zheng nodded, but he didn't dare in his heart.

Besides, makeup and disguise are two concepts, Xu Zheng wants to learn to achieve the effect of disguise through makeup, he estimates that Jin Shiya will only make people beautiful.
