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

Hear the news.

Luo Fei also nodded.

"So that's it."

Hear the other party agree.

Old Han just said.

"But Captain Luo, we do have a case to investigate right now, and it's a very serious serial murder case, so we may need you to come in person."

Hear this.

Luo Fei nodded.

"That's what I said, this is reasonable."

I just saw the other person smile and nodded.

Old Han also said so.

"Team Leader Luo, this criminal is very bad because he didn't commit the crime in our area. Instead, he kept moving between various places."

original.

This time, the suspect always breaks into people's homes under the pretext of repairing their heating systems.

And it's not just in Changli City.

Instead, they committed crimes in multiple places.

only.

all the time.

This guy keeps changing his name.

And every time the victim was silenced by him.

Naturally, no one saw his face.

"In addition, this person should have worn gloves frequently. We hardly found a single fingerprint at the scene."

"You could also say he was very careful in what he did."

"This means that we have no clues at all during the investigation and no way to find other clues."

Hearing this reasoning.

Luo Fei said.

"It's hard to say for sure about this kind of thing. Maybe there's something wrong with the way we think about the problem."

Also.

If this murderer was so rampant, he would have caused some panic in other places.

"This may be a clue to help us find the cause."

Hear this.

Old Han nodded.

"Team Leader Luo, so this case ultimately requires you to come forward in person. After all, with your connections, it would be more convenient to notify these people and contact them to find a way to solve this case together."

Hear this.

Luo Fei nodded.

"I was wondering why you guys are so kind all of a sudden? It turns out it's because of this reason."

"You want me to help communicate with other police stations and ask them for previous clues?"

"Yes, Team Leader Luo, after all, this case is complicated, and there are multiple victims. It would be best if you could come forward."

Seeing Lao Han was very sure.

Luo Fei shook his head.

"It's just a small matter. I believe the other party will be willing to cooperate actively."

And sure enough.

As Luo Fei's call went through.

When I heard that he was going to personally resolve the matter this time.

The people at that police station were also very excited.

"Team Leader Luo, we are really happy that you are willing to personally come forward to resolve this matter this time."

"We are really touched that you can come and investigate this matter in person."

Hear the other person say this.

Luo Fei said it with certainty.

"Everyone, I know you have been investigating this case for a while but have no clues, so let's unite and change our thinking. This will be more beneficial for the next investigation."

Hearing this, the other party also said.

"Team Leader Luo is right."

“It’s just that this case did cause us some trouble, and we have to say that the situation is a bit troublesome.

Hear the other person say this.

There was a hint of sadness in his tone.

Luo Fei's curiosity was also aroused.

"Everyone, if you encounter any trouble, just tell me."

“We work together to find solutions and we can always solve the problem.”

……

"Team Leader Luo, in fact, although this case has already caused a very bad impact, the problem is that we suspect that the murderer committed the crime together with his friend."

"Or maybe it's because someone is helping to cover him up that he can be so rampant."

original.

These police officers re-analyzed the previous case trial process.

They also found out.

This repairman can always get into other people's homes smoothly.

Even if someone is worried and cautious, they will still let him into the house in the end.

This actually very likely means that someone assisted him in committing the crime.

"That's very possible. Maybe someone paved the way for this man, making his subsequent crimes smoother."

When the other party heard that Luo Fei agreed with his idea, he did not comment.

"Team Leader Luo, we can say that we agree on this point. And just recently we found that there was a local housekeeping company, and an employee had clearly registered for work, but suddenly disappeared half a month after joining the company.

The call is not going through.

And he left without any prior notice.

This has already aroused suspicion from others to a certain extent.

"We suspect that this accomplice pretended to be an acquaintance of the elderly, or claimed to be a nanny from a housekeeping company, to get close to the elderly and learn about his financial situation, so as to choose the right prey for himself."

Such analysis.

Jean Luo Fei nodded.

“It does sound reasonable.”

"Perhaps, this can help us further explore the case."

Hear the other party agree.

The policeman on the other end of the phone also said.

"So, Team Leader Luo, when you conduct your investigation next time, perhaps you can start from this angle."

"Have similar situations occurred in local housekeeping companies?"

If there is.

Maybe this criminal is looking for prey.

Hear the news.

Luo Fei didn't feel happy at all.

Even more nervous.

Because there are many local housekeeping companies.

There are also many new employees and resignations every day.

It can be said that the staff turnover is very high.

"If we don't have solid evidence, we can't just arrest people. It will be difficult for us to identify the suspect."

Just when Luo Fei and the others were starting to get worried.

His cell phone has been ringing.

A middle-aged man's voice suddenly came from the other end of the phone.

"Team Leader Luo, I want to report that someone has killed someone."

Hear the news.

Others couldn't help but worry.

"Could it be that the next victim has appeared so soon?"

Looking at other people, I felt a little overwhelmed.

Luo Fei said.

"No, this case is different from the previous ones. The deceased was chopped up and dumped in the farmland."

"And the person before often targeted elderly people who lived alone."

But even though I got the news.

But no one was very happy.

More than half an hour later.

Luo Fei brought Li Yu and the others to the crime scene.

At this time, an older sister was lying on the side of the farmland, crying heartbreakingly. "My son, why did you die? Your death was so tragic. Who on earth was so heartless to harm you?"

In contrast.

An old man and a woman nearby seemed much calmer.

"Officer, the dead man is my husband. His last name is Wang. These two are his parents. I am his wife."

Seeing the other person's face so calm.

Luo Fei noticed something was wrong at the first moment.

It was obvious that this woman was deliberately hiding something.

Or maybe she knew her husband was dead, so her expression was so indifferent.

It's as if it has nothing to do with me.

"Sister, you don't seem to take your husband's death very seriously?

I was a little surprised to see the other person.

It seemed that he had not expected himself to be so calm.

But the elder sister sneered.

"Officer, my husband's death is indeed very sad."

"But when I think about what he did before, I don't think it's strange at all."

Seeing the other party sneer.

Luo Fei also asked.

"What exactly is going on?"

Seeing that the other party was a little puzzled.

His face was full of surprise.

The elder sister explained patiently.

"Officer, my husband has always been like this."

"He's already in his 30s, but he still goes out to gamble with money all day, playing cards with his friends. Whenever he loses money, he asks his parents for it."

"I only found out about this in the past two years. Just thinking about his parents, who are already in their 60s and have to pay off his debts, makes me feel bad."

Having said that, the eldest sister sighed.

He seemed to be trying hard to control his emotions.

"So now that he's gone, those debt-evaders will probably be able to stay quiet for a while."

"I also plan to move out with my children after a while so that I can have some peace and quiet."

Now the others finally understood.

Why this woman doesn't care at all about her husband's death.

Obviously, she had been victimized for too long.

So I am very dissatisfied with my husband.

"Officer, to be honest, after I found out about this, I even proposed divorce to him. I told him that he should either find a way to pay back all the money himself."

"Otherwise, you wouldn't have to ask your parents to support you anymore. They only earn a little money in their lifetime. And they actually gave all that money to you to squander?"

no doubt.

This woman really cares about her parents-in-law.

At the same time, it is also for the sake of the child. She doesn't want him to be influenced by her husband in the future.

But unexpectedly, her husband not only didn't listen.

He even had sex with her several times.

She was covered in bruises.

"So, officer, I am very sure that my husband died because he offended someone outside and they attacked him because he couldn't pay the money and had a stubborn temper."

The eldest sister's tone was very affirmative.

It felt as if the husband was the first to take action, which led to this outcome.

Such news.

This made Luo Fei even more suspicious of this elder sister.

"Sister, although we feel that your experience is very sympathetic, we still need to make sure that this incident was not done by you. So we may have to go to your home to check and see if there are any clues that can prove that your husband's death has nothing to do with you."

Hear the news.

The eldest sister pursed her lips first.

But I still agreed readily.

"No problem, officer, please follow me."

While they were talking, Luo Fei and Li Yu were also there.

So I followed my eldest sister to her home.

But just as I entered the house.

Luo Fei smelled a strange smell.

It was obviously bloody.

Although there was a distinct smell of detergent, it covered most of the bloody smell.

But Luo Fei's keen sense of smell enabled him to immediately discover something was wrong.

"Big sister, did you just kill a chicken or something at home?"

Luo Fei's words made the woman nod repeatedly.

"Yes, we held a banquet at home a few days ago. Since our yard is quite large, many people in the village came to our yard to eat."

But after hearing this, Luo Fei glanced at the wall next to the kang.

There are obvious signs of deliberate sanding on it.

Even a layer of the wall paint on top had fallen off.

Then he lifted the quilt at the head of the kang.

The bloodstains below were also shown to others.

"Sister, what's going on?"

Seeing Luo Fei's puzzled look, the woman hesitated for a moment, then pursed her lips.

Because she saw it too.

There is actually a lot of dark red powder in the cracks in the wall at the head of the kang.

It was obviously dried blood.

"Well, I, I don't know either..."

But although Zhang Xiulian tried hard to remain calm.

But her expression betrayed her.

After realizing this

Luo Fei took another look at the stove next door.

As he opened the big pot.

I took a closer look at the bottom of the pot.

Zhang Xiulian couldn't hold it in any longer.

"Officer, I admit that I killed my husband."

Hear this.

The old man beside him was shocked.

"Xiu Lian, why are you doing this? Our son has been with you for more than 10 years, how could you treat him like this?"

"Wow, my son was already over 30, how could he be gone? This is all your fault, my son..."

I saw my mother crying hysterically.

Zhang Xiulian said this very seriously.

"Officer, isn't this obvious?"

"I can't bear to see my parents-in-law suffer and be dragged down by this son. Especially me, the mother-in-law, she dotes on her son too much. Otherwise, he wouldn't be like this today."

Seeing the other party say this.

I couldn't help but sigh.

She was clearly disappointed with her husband.

Luo Fei also put a silver bracelet on her.

Zhang Xiulian pursed her lips and said.

"In fact, I didn't want to kill him at first. I just begged him not to play around with money anymore and not to burden his parents anymore.

But he said they were his parents and I had no say in that.”

"I didn't know what I was thinking at the time. I was probably too angry, so I grabbed the bottle of wine on the bedside table during the argument. I really didn't want to kill him."

In a trance.

Zhang Xiulian was taken to the police station.

While asking for details.

Luo Fei also asked.

"Ms. Zhang, the manager just said that you had a banquet at home. Did you kill someone before the banquet?"

"Yes, that was three days ago."

"When I saw him dead, I really didn't know what to do, so I cut off his head and burned it to ashes under the corridor."

Plus the weather has been quite cold recently.

"I simply put the rest of its body into the side room and locked the door."

"I was so sleepy at the time that I planned to get up the next day to deal with the remaining body parts, but someone from the village wanted to use my yard, so I couldn't do it in case someone discovered me. So I had to wait until they left and drag the bodies to the place where I had just been and throw them away while it was still dark. But I didn't expect that someone would still discover them."
