Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 288 Restoration of the scene

"The current situation has two breaking points."

Luo Fei looked at the people on the side.

"First, although the criminal entered the floor, his way of coming and going was different, and he was not in a hurry. This shows that he is familiar with the structure of the building and the surveillance blind spots in the community. There are not many such people. .”

"Takeaway people, couriers, security guards, even those who deliver milk are all suspects, but they must be connected to the family of the deceased and be tied together to investigate."

"Second, this person was very familiar with the situation in the deceased's home, and even knew the location of the kitchen knife, which shows that there must have been records of entry and exit before."

Speaking of this, everyone looked solemn.

In this way, it seems that the detection range and the direction of suspicion are basically determined.

"In recent times, all surveillance has to be checked."

"Normally, surveillance records are kept for seven days, but high-end communities like this will be more comprehensively prepared, maybe half a month later. Everyone should investigate and verify the identities of outsiders entering and leaving the building."

After a brief explanation, everyone started taking action.

Because of Luo Fei's practical ability and precise judgment, he became the backbone of everyone at this time.

Zhao Donglai came over and got a bottle of water for Luo Fei.

"If the murderer is still hiding in this community, I'm afraid we have to be careful."

"Yes."

"No one knows which family he has enmity with. If he hides and kills in secret, someone will probably die under our noses."

Hearing what Luo Fei said, Zhao Donglai nodded heavily.

"What should we do next? Should we seal off the entire community first? Although there is something wrong, the guy should not have gone out yet."

"No."

Luo Fei directly rejected the other party's idea.

"Captain Zhao, directly blocking people can indeed trap people here, but if because of identity issues, he starts to take action on those innocent people, killing people when people are panicked, we will definitely lose more than the gain."

"I even suspect that this person is a pervert. At present, there is no way to analyze his motive for committing the crime. If he has mental problems, it may be difficult to deal with."

"Well, that makes sense."

Suddenly, Luo Fei turned his attention to the middle of the crime scene again. All he could see was an empty marked area, and the body had been taken away...

Perhaps there are some truths that cannot be seen only from the surface, but also from the side.

"Captain Zhao, I'll go in and take a look. You guys should wait outside first."

"it is good."

When Luo Fei was the only one left in the room, he immediately came to the sofa and sat down, imitating the scene before the death of the male owner.

There were no other signs of fighting on his body, which meant that the opponent was subdued with one move.

There isn’t even a single shoe mark on the body!

Because Luo Fei remembered very clearly that when he first saw the deceased male, he was wearing a gray sportswear at home.

If there were signs of a fight, there would be signs, but apart from the blood on the chest and two kitchen knives, there were no other traces.

"To pass through the body with a knife, it requires enough violent strength, and it must have amazing arm strength."

"Who can do such a violent thing? A worker? Yes, killing people with steel bars, and using building materials that meet the specifications and standards on the construction site. Maybe they really belong to the construction site."

"No, why did they have a grudge? The murderer even knew that their family had the habit of drinking milk. This is not like ordinary people who only have a one-time acquaintance or have an average relationship."

Luo Fei sat up from the sofa and suddenly saw the TV cabinet opposite.

The area under the TV cabinet has moved a little, probably due to collision.

The white line on the ground next to it is the location where the woman died.

Judging from this, someone should have acted too hastily, bumped into the TV cabinet, and knocked it sideways.

Suddenly Luo Fei remembered the knife wound on the woman's body.

There were several more cuts under her ribs with the kitchen knife. If this was the case, then the kitchen knife had severely injured the woman before it penetrated the man.

In this way...the picture is there.

The restored scene appeared before Luo Fei's eyes.

The door opened slowly, and a figure rushed in from the outside. It was the murderer wearing a mask and dark green wings.

The hostess immediately stepped back after seeing the other party. Because the kitchen was behind the entrance hall, she retreated into the kitchen first.

The fear of the unfamiliar crisis completely broke her defenses, and she even forgot to resist.

Because in the panic, I ignored that the kitchen was a dead end. Once I entered, it was difficult to get out. There was a high possibility of being buried here.

After entering, the murderer took the kitchen knife from the side and struck hard.

However, the opponent was not killed on the spot. She probably ran out, and then the murderer took the opportunity to draw a second knife from the side. With both knives in hand, he killed him.

Just at this moment, the male host rushed out and chose to fight in order to protect his partner.

However, a kitchen knife was inserted into his chest, and the blood spurted out, which was extremely tragic.

The woman on the side was so frightened that she had no time to think and was about to run out.

The murderer put his bare hands on the man's chest, pushed him all the way back and pinned him to the sofa.

Solve one, and there's still another.

In a panic, the woman bumped into the TV cabinet and was pinned to the ground by the other party with steel bars. This was enough to kill half of the other party's life, and there was basically no chance of survival.

Luo Fei pinched his eyebrows and his eyes began to become gloomy.

"No, it's still wrong..."

"If this is the case, then the steel bar was not brought in by the other party, because if the steel bar was used as a murder weapon, the man would be the first to die. Why was it used on this woman in the end?"

A headache came over him, but in this small area, Luo Fei couldn't figure it out.

No matter how I tried to restore this scene, I still could not get the optimal solution. It seemed that there must be something I had overlooked.

right! That’s right, rust!

Luo Fei suddenly remembered that there was some rust on the steel bar. The rebar was stained with moisture and produced scale rust. Although it was very small, he had already noticed it when he entered the door and saw the scene.

If there is such a smell in the house, it proves that the steel bar was originally placed in the house.

That is the power hidden deep in the genes of your body.

Police dog level sense of smell! The most subtle taste cannot escape its own detection.

After some searching, Luo Fei walked into the kitchen and found some light yellow rust marks on the ground next to the refrigerator, which should have been left by the steel bar.

Sure enough... there is no such thing as a construction site suspect.

All the murder weapons came from the deceased's home!

In this way, the order of the opponent's shots is basically clarified. The steel bar fell to the ground during the fight in the kitchen, so after killing the man with the kitchen knife, the murderer picked up the steel bar and gave the woman a heavy blow, and then slashed her ribs and abdomen with the knife.

Silence? No need, just run away at this time.

Because the wound caused by the steel bar was not small and bleeding came out, the young couple was destined to die.

So the only possibility of the stab wound was to vent his anger...

As for why the kitchen knife was stabbed back into the other side of the man's body in the end, it might have been a temporary move or it might have been intentional, it's hard to say.

"Then all that's left is the motive."

Luo Fei stood up and walked out naturally muttering to himself. Although he had analyzed the order of killing and what the perpetrator basically did, the motive was the most difficult thing.

When I walked to the entrance of the corridor, I saw several police officers not far away asking the neighbors about the situation.

This community has four terraces and eight households, and each corridor has four households.

The neighbors of the other three households are currently under investigation. They are all looking here uneasily, and it can be seen that they are very scared in their hearts.

Luo Fei expressed his understanding. After all, there was such a serious murder in his community.

From their mouths, everyone heard a completely different couple.

The man’s name is Hua Guoyu and the woman’s name is Meng Ling.

"Hey, these young couple are good at everything, but their tempers are not very good. They used to have conflicts with others, but just because of the quality of life they pursue, several delivery people have been brutalized."

"Yes, that's what happened. The young man was fine, but Xiao Meng was really irritable, because he often got into trouble with me about the garbage and furnishings in the corridor."

"One more thing, Xiao Meng often looks down on the sanitation workers, security guards, and property staff in our community... She has disliked all of these, which makes people very embarrassed."

Everyone's reviews of this pair are not very good.

Especially Meng Ling, not to mention being kind to others, can't even show the most basic respect, which makes people very helpless.

Luo Fei suddenly pulled over a middle-aged woman next to him.

"Auntie, let me ask you whether there are any community workers in our community who have had major conflicts with these two people. This is very important to us. Please recall it carefully."

The other party also thought seriously after hearing this. It should be true that such a thing happened, but he didn't know how to organize the words.

"It starts from the beginning. It's been two years since they moved here."

"When we first came here, a security guard helped them, delivering groceries and helping to clean up the house. I happened to be returning from shopping for groceries, and when I passed by their door, the security guard was about to go downstairs."

Speaking of this, the middle-aged woman's eyes began to become angry.

"The door was still ajar, and before the security guy left, Xiao Meng started talking with her boyfriend inside. Either she was dirtying the ground or messing up her home..."

"Oh, I couldn't stand it anymore, but the security guy had already left."

"After that, I met him several times in the community. Xiao Meng seemed to be not very kind to each other. He was either sarcastic or contemptuous."

"Comrade police, you said that the security guard has a hard time protecting the safety of the community, but she only caused trouble for them."

"Parking indiscriminately, putting things indiscriminately... Her bag was left at the security booth and her husband took it home. She insisted on saying that the security guard had taken it, and she wanted to complain and was sarcastic and abusive, which made it difficult for her to get off the ground."

Luo Fei also frowned upon hearing this.

This can be considered a bad deed! In such a high-end community, the quality is so low, and I am convinced.

"Auntie, do you know the name of that security guard?"

"This is so clear. I heard the security captain always call him Xiao Liu."

"Okay, I understand, thank you for your cooperation."

After Luo Fei finished speaking, he was leaving.

The woman took another look at the house in front of her where the murder took place, and couldn't help but sigh and shake her head. She was not only lamenting that the person's death was still a sinful past.

Liao Xingyu, Zhou Fan, and Li Jun also gathered around and explained what had just happened. They also roughly learned about the deceased's situation from the mouths of several other residents.

But because they don’t have much contact with each other, what they know is limited.

"If that's the case, the motive is established."

Luo Fei nodded thoughtfully.

Liao Xingyu proposed.

"Let's go back first. If we can't find the murderer, we can wait."

"can not wait!"

Zhou Fan was the first to interrupt him.

"We don't know how many people this murderer has grievances with, or whether he likes killing because of a psychological abnormality. If we continue to let him stay here, it will not be safe. We must find him as soon as possible."

"Yes, if we can't find it, we won't go back tonight!"

Liao Xingyu and the others also nodded in approval.

Seeing that everyone was ready, Luo Fei smiled.

"It's not that exaggerated. I already have a guess that is very consistent with the current situation."

"As long as a person plans to run away after committing a crime, it is because he does not want to be exposed. Such people must keep their true identity after all. If they act abnormally, they will definitely attract the attention of others."

Everyone nodded after hearing this.

"Okay, then I can tell you that the biggest suspicion currently falls on the security guards of this community."

"The delivery boy and the milk delivery are not enough to occupy all the doubt points, only the security guard!"

"There are three clues!"

"First, when I went down from the security passage, I found a footprint on the window sill on the first floor. Although it was blurry, it was indeed high-top boots, which are part of the security uniform. Jinguiyuan's property requirements require that security guards wear It’s unified.”

"Second, only the security guards are familiar with the escape area and know that the surveillance behind the safe passage cannot capture it. This is something that the delivery personnel cannot understand."

"Third, and most importantly, the motive."

When it came to this, Zhao Donglai was the first to react.

"Luo Fei, you are saying that the relationship between the deceased and these community workers was so bad during his lifetime that it triggered revenge."

"It's just some minor conflicts between each other. Will the relationship between the owner and the security guard be so bad that they kill each other and silence them?"

"I always think this is impossible..."

Just when everyone was hesitating, Luo Fei suddenly spoke.

"When there are no other possibilities, even the most incredible reason is the only explanation."

These words instantly awakened the others. They were rough words but not rough. Luo Fei's judgment really stood up to scrutiny.

"Let's go to the security room!"
