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

"I asked several of Zhou Guohua's neighbors, and an old couple in one of them said that at noon on May 18, the day Zhou Kairui disappeared, he had heard the cry of a child from Zhou Guohua's house."

"At that time, he thought it was Zhou Guohua's grandson coming back from the hospital, and he was going to ask how the child was doing, but he didn't know that no one answered the door after knocking for a long time. In addition, he didn't hear the child's cry again, so he thought he had heard something wrong. Well, I didn’t take it seriously.”

"Then this cry is probably Zhou Kairui's! Team Leader Liao, have you confirmed this problem with other neighbors?"

Liao Xingyu shook his head, "I've asked, but others said they didn't pay attention."

Everyone was a little disappointed after hearing this.

Zhou Fan encouraged, "Don't be too depressed, everyone. This at least proves that our efforts today were not in vain. There was indeed someone at Zhou Guohua's house that day."

"According to their neighbors, Zhou Yucheng fell ill on the 24th, and his family sent him to the city overnight. In other words, Zhou Guohua should have returned to the village before 11 a.m. to commit the crime."

"But today, no one in their village said they had seen the father and son come back. This should be because they consciously avoided the villagers, but the town has a dense flow of people. No matter how careful they are, they may bump into a few acquaintances."

"In this way... I suggest that we increase our efforts to visit the town tomorrow. Maybe we can find something."

"That's all it can do now."

"Okay, then go to bed early and take action immediately when you wake up tomorrow morning!"

The night passed.

Everyone got up at around six o'clock in the morning. After breakfast, we started to visit the town as agreed last night.

The town is different from the big city, because the faces that come and go every day are basically the same, and over time they will have impressions of each other. This is probably a major feature of rural towns.

Therefore, it was relatively easy for them to get up. As long as they showed their photos, the merchants in the town could basically recognize the father and son.

But once asked if they had met the father and son on May 18th three years ago, everyone just shook their heads.

"Comrade police, we can't remember what happened for so long."

"I'm sorry I don't remember. People come and go here every day, not to mention it was three years ago."

"..."

I asked several companies in succession and got the same answer.

After coming out, Lin Jie couldn't help but said, "Team leader, I don't think this is reliable at all."

"If it's okay for a month or two, maybe everyone can still remember something, but who can remember what happened four years ago so clearly?"

"We all know what you said, but the key now is not that there is no evidence, then we can only try our luck."

As the two of them talked, they walked into a tire repair shop.

After revealing his identity to his boss who was sitting on a tricycle playing with his mobile phone, Luo Fei immediately took out the photos of Zhou Dahu and his son.

"Boss, take a look, do you have any impression of these two people?"

"This is not Zhou Dahu. We are junior high school classmates. Of course we know each other."

"Comrade police, what are you looking for him for? Has he committed a crime?"

"Don't worry about this. We just want to ask, did you see him in town in mid-May three years ago?"

"Three years ago..." The boss hesitated.

Just when Luo Fei and the two thought that this trip was going to be in vain again, their boss suddenly asked, "Is it the time when his child was hospitalized and needed surgery?"

This...could it be a drama? !

Luo Fei was overjoyed for a moment, "Yes, it was that time, do you remember it?"

"I remember, it was May 18th, my father-in-law's birthday, so I closed the shop at four o'clock that afternoon and took my wife and children back to my father-in-law's house for dinner."

"My father-in-law is in the village next door to them. People from Baimao Village have to pass by their village when they come to town. Everyone was there that night, so my uncle and I had two more drinks. When we came back, it might be ten or eleven o'clock. Clicked."

"When we drove to Datian Dam, a figure suddenly jumped up on the side road. If I hadn't stepped on the brakes quickly, I almost hit him..."

"So you drove drunk?" Luo Fei suddenly said.

The boss who was talkative just now was speechless for a moment, with a look of annoyance on his face.

He secretly thought that he didn't know what to say, so why did he tell this matter?

"Actually, I didn't drink much, just a few drinks...Comrade police officers, you don't even care about the work of the traffic police."

"Don't worry, this is not our responsibility. But for the sake of your family's health, you better not do this kind of thing in the future. If something happens, it will be too late to regret it. Even if nothing happens, being found out will affect your child's exam."

"I understand, understand. Just that one time, I will never drink while driving again, I swear!"

Luo Fei reminded him a few words, and didn't care whether he was telling the truth or a lie.

"Go on and tell me, after you came back from your father-in-law's house, when did you bump into Zhou Dahu in the town?"

"Because the person I almost bumped into was Zhou Dahu."

What a coincidence?

Luo Fei and Zhang Wei looked at each other, excited.

"Boss, can you tell us about the situation in detail?"

"I almost bumped into someone at that time. I was so frightened that I woke up completely. Then I wanted to get out of the car and argue with the person. But when I saw it, I realized it was that guy Zhou Dahu."

"I was quite baffled at the time and asked him why he took a small road instead of the main road. If I hadn't reacted quickly, his life would have been taken."

"He just said that the child at home was sick and needed an operation but he still lacked some documents. He came back to get the documents. Because he wanted to take a shortcut, he took a small road, but I always felt that he didn't tell me the truth."

"Why?"

"How should I put this... I just opened the door that morning, and I happened to see his father passing in front of my store, heading back to the village, but he was very anxious to see his back, so I called him twice from behind. Ignored me."

"So if there is really a lack of documents, and the old man sent them to the city during the day, why would he have to run back in the dark to get them in the middle of the night?"

"Then have you asked him this question?"

"No, these are other people's family affairs. How can I ask these questions? But I guess he came back specially to give the child some remedies."

The boss couldn't explain what he was saying, "I don't even know what to say about my classmate. He is in his thirties, but he has a single mind."

"I have advised him before that he should treat the child as the doctor says. He is at least more professional than us, right? But he insisted that surgery is very harmful, and anesthetics can also affect the child's intelligence. The family just searched everywhere for home remedies. .”

"As it turned out, the child's illness was not cured, and all the money he earned from working as a contractor over the years was spent on it... At that time, I knew that he was in a hurry to rush back to the city, and I heard that the car he ordered was waiting for him in the town, so I just took him back to town."

After getting this clue, Luo Fei called Zhao Donglai as soon as he came out of the car repair shop.

"Team Zhao, I suggest that Zhou Guohua and his son be summoned immediately. In addition, I apply to search Zhou Guohua's home."

With the confession from the owner of the car repair shop, Zhao Donglai did not object, "Okay, you can go directly to the village cadres in the village. I will send the search procedures to your mobile phone later."

"clear."

Luo Fei informed Liao Xingyu and others separately.

In the end, it was decided that Luo Fei and Liao Xingyu would lead the first and second groups to search the Zhou family, while the rest would stay in the town and continue the visit.

The group went to the local village committee again. After taking out the search procedures, several village cadres were very cooperative and immediately accompanied them to Zhou Guohua's home.

Witnessed by several village cadres, they directly went to the town's locksmith to open the door lock of Zhou Guohua's house.

Opening the door, you are greeted by lush green.

Because it had not been taken care of for a long time, the yard was overgrown with weeds, and there was almost no place to stand.

Luo Fei stood in front of the gate, glanced casually, and suddenly his eyes were fixed on the land under an orange tree beside the courtyard wall.

"He Xin, you go to the people's house nearby and borrow two hoes, and dig under the tree to see if there is anything inside."

Seeing the black gas constantly coming out of the land, Luo Fei was not in a hurry to go into the house to search for physical evidence.

After giving the instructions, he immediately pushed aside the weeds and walked towards that place.

Liao Xingyu followed him.

"Luo Fei, what's wrong with this land?"

"Um."

Seeing him nodding, Liao Xingyu suddenly murmured.

Luo Fei is so amazing, right? He can tell something is wrong with this piece of land just by looking at it?

Without explaining anything to him, after He Xin and the others borrowed hoes, Luo Fei pointed to a place and asked Zhang Wei and He Xin to dig.

After just a few digs, He Xin felt his hoe hit something.

"Wait a moment!"

He immediately called Zhang Wei to stop, then squatted down and began to dig with his right hand. Soon a corner of the cloth whose original color could no longer be seen was exposed.

The two of them started working together and soon dug out a ball of cloth. Judging from the style, it should be something like a bed sheet.

Opening the ball of cloth, there was a child's coat, two rusty kitchen knives and daggers, and a small tiger stuffed inside.

Almost at a glance, Liao Xingyu and others present were sure that the coat and doll belonged to Zhou Kairui.

Because these items appeared with the characteristics described by his grandmother when she and her child were lost.

Liao Xingyu became excited instantly.

He looked at Luo Fei in disbelief, "I'm going to Luo Fei, how did you know there's something buried under here?!"

As soon as these words came out, Zhang Wei and others also looked at him curiously.

Luo Fei had already thought of a countermeasure and calmly pointed to a few burnt incense candles stuck in the soil beside him. "It's very simple. They can't be paying homage to this tree."

If it’s not a memorial tree, it can only be a person.

But if you want to pay homage to your deceased relatives, you can go to the grave to pay homage. Why should they pay homage at home? Unless they dare not go to each other's grave to pay homage.

Wanting to understand this, Liao Xingyu gave Luo Fei a thumbs up, "Gao, Luo Fei, your powers of observation are indeed too strong!"

"Team Leader Liao, I'll leave this to you. I'll go to the back of the yard and take a look."

"Okay, go ahead... Gao Gao, hurry up and get some evidence bags. He Qiang, evacuate everyone and seal off this courtyard immediately."

"And Lin Jie, when you take photos and videos, remember to give some close-ups of these two knives. I suspect these may be the murder weapons. Su Yang immediately called Team Zhao to inform Team Zhao of our findings."

Under the arrangements of Liao Xingyu, everyone was busy in an orderly manner.

The criminal policeman named He Qiang also walked towards the onlookers.

Just now, so many of them came to open Zhou Guohua's door, which aroused the curiosity of many villagers.

At this moment, everyone was standing in a circle, talking about what the police had dug up.

He Qiang spent a lot of time before letting them disperse.

Here, Zhao Donglai was also excited after receiving Su Yang's call.

If the murder weapon is really found, then most of the case will be solved.

He immediately called Li Jun.

"Li Jun, Luo Fei and the others are suspected of digging up the murder weapon at Zhou Guohua's house. You should take someone there immediately and send the things back for comparison. And by the way, pick up Zhou Guoan and ask him to identify and dig them out. Are the clothes belonging to Zhou Kairui?"

"receive."

After receiving the order, Li Jun immediately called the members of the three groups to gather.

Several people first rushed to the fourth group to pick up Zhou Guoan, and then went to Zhou Guohua's second group.

At present, it is almost certain that Zhou Guohua and his son committed the crime.

Moreover, he would be needed to identify the evidence later, so there was no need to hide anything. As soon as they got in the car, Li Jun briefly explained the situation and their suspicions.

Zhou Guoan certainly couldn't believe such a ridiculous thing for a while, and kept repeating the impossibility all the way.

However, when Liao Xingyu took out the child's coat and doll he dug out of the soil, he felt as if he had been struck by lightning.

If he hadn't been supported by Li Jun, he almost fell down.

"Yes, these are Ruirui's clothes. It was a bit cold that morning, so his grandma put on a coat to prevent him from being cold. And this doll is Ruirui's favorite toy. Comrade police, where did you find these? Something?"

Zhou Guoan's eyes were red, and he made a mistake in holding on to his last glimmer of hope.

How could this thing be dug out of his eldest brother's house?

He is Ruirui's uncle, and he has never offended him, so he will definitely not be so cruel!

"Uncle Zhou, I hope you can calm down... these things were definitely dug up by us at your eldest brother's house."

Zhou Guoan's mind went blank for a moment.

After a while, he became angry and said, "Zhou Guohua, you beast..."

After they were all gone, Li Jun said a few more words and returned to the city with the evidence.

Luo Fei and Liao Xingyu conducted a detailed search inside and outside Zhou Guohua's home, but unfortunately nothing useful was found.

Finally, everyone rushed to the town to meet up with others and prepared to go back.

Back at the police force, Luo Fei and others first went to Zhao Donglai's office to report the situation.

Then Zhou Fan asked, "Captain Zhao, where are Zhou Fan and the others?"

"Just now you said that evidence was dug up at Zhou's house, so I asked the local police to control Zhou Guohua's family, and Zhou Fan and the others went to pick them up."

"So that's it."

At this time, Zhao Tian knocked on the door and walked in.

"Captain Zhao, the results of the comparison just now are out."

"According to the original autopsy, Zhou Kairui's chest was first chopped open with a sharp weapon, and then his heart was cut out and removed with a sharp weapon."

"After comparing the two knives found by Team Leader Luo and the others, they are consistent with the knife marks caused by Zhou Kairui's body, and they are definitely the murder weapons."

"It's a pity that the sheet outside has been buried for too long, and no useful clues can be found on it."
