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

"Actually, Yan Shu didn't plan to hold this birthday party, but I told him that this way he could see Zhao Miaoxue more often, so he agreed."

"Zhao Miaoxue looks very similar to Yan Shu's deceased mother, which is why he treats her differently from others."

Zhao Miaoxue felt complicated and shed tears silently.

If it weren't for her, Chen Yanshu might not have paid such a heavy price.

Luo Fei saw what Zhao Miaoxue was thinking.

"You don't have to blame yourself. Even if there wasn't this party, she wouldn't let Chen Yanshu go. It's just a matter of time. Once these thoughts come into her mind, she won't give them up easily."

Poor Chen Jingzhou, he is still so young and has to face future difficulties alone.

Ms. Chen burst into tears, but it was too late to regret.

"You can't take my mother away, so take me away."

When Chen Jingzhou learned the truth, he felt even more guilty.

If he wasn't so disappointing, why would Mom take such a big risk?

But those who do wrong will definitely pay the price.

Luo Fei said earnestly: "Chen Jingzhou, you must take good care of yourself in the future, so as not to let Chen Yanshu down for his kindness to you."

"I see."

The matter was done, and Chen Jingzhou lowered his head sadly.

After walking out of the villa, Li Yu felt very strange.

"Team leader, how do you know that Chen Yanshu treats Chen Jingzhou well? They are not real brothers."

Luo Fei raised his eyes.

"Didn't you hear what Chen Yanshu said to Chen Jingzhou? He really treats Chen Jingzhou as his brother and a member of the family."

Li Yu sighed.

"This woman took the risk for her son, but in the end she didn't even have the chance to be with her son. Once evil thoughts arise, there is no way back."

Having said that, this was Ms. Chen's own choice and she cannot blame anyone else.

Luo Fei turned around and saw Xia Chenxin and Zhao Miaoxue standing next to Chen Jingzhou with smiles on their faces.

"Don't worry, he won't be too lonely."

"I hope so."

When he returned to the police station, Su Jianfan was surprised to see dozens of boxes of various sizes, all filled with toys.

"Whose are these? Why are there so many toys?"

A middle-aged man wearing glasses smiled bitterly.

"I brought them here, but I didn't buy any of these."

Everyone felt puzzled.

It was obvious that this man was in deep trouble.

Old Han came over and said in a deep voice, "Sit down and talk."

"it is good."

The man is a doctor in a large hospital and his surname is Zhang.

He came to this city five years ago, and everything was going well.

Two years ago, someone mailed him a toy.

Since then, he has seen such express deliveries every month.

Su Jianfan was very curious.

"You really don't know who gave it to you? And you haven't looked for that person?"

Doctor Zhang waved his hands in distress.

"I also tried to find this person, but in the end I found nothing. The mailing address would change after a period of time."

"After a while, I got used to it. Until yesterday, I saw such a delivery again. It was this big toy and a letter. Please take a look."

Doctor Zhang has been feeling a little uneasy these past two days.

Generally speaking, if someone can get a bargain, as long as it doesn't cost anything, there will be many people willing to accept it.

Doctor Zhang didn't know what purpose the person hiding in the dark had, but he had a very bad premonition, so he went to the police station to report the case.

After opening the letter, Luo Fei frowned.

"That person said we can meet tomorrow, so maybe we'll know the answer tomorrow."

Doctor Zhang said hurriedly: "That being said, I don't dare to go see this person like this, nor do I dare to let my son see him."

Hearing this, Su Jianfan had a guess.

"You have a son, so maybe these toys were bought by the other party for your son. How old is your son this year?"

"After tomorrow I'll be six years old."

Tomorrow is Dr. Zhang’s son’s birthday?
Isn't this too much of a coincidence?
Li Yu put forward a hypothesis.

"Doctor Zhang, you must have saved a lot of people. It's not impossible that those patients secretly mailed you so many toys out of gratitude."

Doctor Zhang was very helpless.

"If only it were that simple. Anyway, tomorrow is my son's birthday, and there must be no mistakes. Please help me find this person quickly."

Old Han nodded.

"We will."

After taking the statement, Dr. Zhang had work to do, so he left the police station.

As a father, everyone can understand that he is worried that these things will affect his son.

It was the appearance of this letter that made Dr. Zhang so nervous.

But it is not an easy task to find the person who has been hiding in the dark for two years within one day.

Luo Fei had a serious expression on his face. He called his colleagues in the technical department and asked them to bring the toys and the letter over.

I just hope to get useful clues as soon as possible so that I can make the next arrangements.

"This person is really weird. Why does he have to use this method? Even if he wants to thank Dr. Zhang, he doesn't have to do this, right?"

Luo Fei said in a deep voice: "That person could have mailed other things, but he insisted on mailing toys in the past two years. This means that from the beginning, that person was targeting Dr. Zhang's son."

Hearing this, everyone couldn't help but gasp.

How could a six-year-old child be connected to such a person?
If Luo Fei's guess was correct, perhaps the person hiding in the dark was not seeking to repay a favor, but to seek revenge!
This means that Dr. Zhang’s son will be in danger!
"Team leader, is that possible?" Su Jianfan still found it hard to believe.

If that person really had bad intentions, he would have found an opportunity in two years. There would be no need to wait so long, right?
Luo Fei continued, "I'm just guessing. There's no evidence yet. We can only wait and see."

"Ok."

A few hours later, there was news from the technical department, but it was not a result.

Just as Dr. Zhang said, the mailing address has been changing all the time, and we have found more than a dozen addresses so far.

Su Jianfan was helpless.

"Team Leader, do we have to go to so many places in one day?"

Luo Fei hesitated for a moment.

"Not everyone can go there. This will only waste everyone's time. Old Han, follow me to the hospital to find Doctor Zhang and see if we can find any new clues there."

"Su Jianfan, Li Yu, the two of you go to these places and check to see if the person who mailed these toys is the same person?"

"Okay." Luo Fei suspected that there might be more than one person who did this.

Until the results come out, we can only be more careful.

Arrived at the hospital.

Doctor Zhang had just finished his work and was very surprised by the arrival of Luo Fei and Lao Han.

"Officer, why are you here? I was about to get off work."

Luo Fei said seriously: "If it won't take up your time, then take us to your office. Not only that, it would be best if we could find a list of all the patients you have seen since you came to this hospital."

This is indeed a huge workload, but this is the only way to find this person as soon as possible.

"Okay, please wait here for a moment. I'll go get the information."

"it is good."

While waiting, Lao Han looked around the room.

"Team leader, there's nothing special here, but we can see that Doctor Zhang is usually very frugal."

You can tell this just by looking at the water cup that Dr. Zhang uses and some other things.

Luo Fei smiled and said, "I saw it when he showed up at the police station. Didn't you notice that his clothes were very simple and even his glasses were cheap?"

"Many of those toys were still packaged in good condition. It's conceivable that he himself would not be willing to buy such good toys for his son under normal circumstances."

"That can be judged. At least the person hiding in the dark is in better condition than Dr. Zhang. Moreover, he keeps changing his address without getting tired of it, which is even more intriguing."

Even colleagues from the technical department were unable to find any useful clues directly, which shows that the other party is very cautious in doing things.

The more such a person is, the more scheming he is.

Who knows, the other party might be very capable.

Old Han was a little distressed.

"I don't know what that person is going through all the trouble to do."

Luo Fei looked at Doctor Zhang who was walking towards him from a distance.

"You'll find out soon."

Doctor Zhang placed the information on the table and frowned slightly.

"Officer, here is the list of patients I have seen in the past few years, but it is like looking for a needle in a haystack to find some useful clues in a short time."

Luo Fei looked through the records.

"It's not that hard to find. The person wrote in the letter that they would meet tomorrow, so let's find the list of people who had seen the doctor on that date before."

"it is good."

Based on past experience, Luo Fei always felt that the person chose tomorrow to meet, which must have some special meaning.

Doctor Zhang's mind was not on this matter. He seemed completely absent-minded and didn't even want to act.

Luo Fei said in a deep voice: "Do you have anything else important to say?"

Doctor Zhang said hurriedly, "Officer, I'm so sorry, I have to go back early. I told my son that I have to be home before eight o'clock."

"Well, go ahead."

Only then did Dr. Zhang feel relieved and was filled with gratitude towards Luo Fei.

"Thank you very much. If you have any problem, you can call me at any time. I will definitely cooperate with your work."

"kindness."

Doctor Zhang turned and left, but Old Han seemed somewhat dissatisfied.

"What this person said was really nice. He was the one who went to the police station to report the case. This is the most critical moment to find that person. How could he leave first?"

"Why are you talking about cooperating? You might as well stay here."

Having said that, there is one thing that Lao Han doesn't know.

Luo Fei had just learned that Dr. Zhang's wife divorced him five years ago.

It was because of the changes in his marriage that he brought his son to live in a new city.

The father and son depend on each other for survival, so of course he would worry about his son's situation.

"You don't know the situation at his home. He's so nervous because there's no one else at home to help take care of the young children."

"Okay, stop complaining and look for it quickly."

"Ok."

Knowing these things, Lao Han didn't say much.

They had nothing else to do at the police station, so they stayed in the hospital.

Because he was wearing casual clothes, no one else suspected anything.

Only a few of Dr. Zhang's colleagues knew the identities of Luo Fei and Lao Han, and they helped them get a lot of things in order to find clues as soon as possible.

Three hours later, they still found nothing.

The young man came over and brought two cups of hot water.

"Two officers, it's been over three hours. You should take a break."

Looking at the person in front of him, Luo Fei had a smile on his face.

"You are quite patient. Do you usually get along well with Dr. Zhang?"

The man nodded without hiding anything.

"Yes, I came here two years ago. Doctor Zhang is my senior and he always helps me. I am very grateful to him."

"He has encountered a difficult problem this time. Although I can't help him, I won't stand idly by."

The man was grateful and knew how difficult this matter was to resolve and that he would get into trouble if he was not careful, but he did not avoid it. Instead, he chose to stand firmly by Dr. Zhang's side.

This also shows that Dr. Zhang must be an easy-going person.

"You know about the toys, too?"

The man sighed.

"Yeah, this is really outrageous. I don't know who the person hiding in the dark is. I really hope we can find him quickly."

Wait a minute!
Old Han raised his eyes and looked at the young man with confusion.

He just said that he came here two years ago?
Isn’t this the same time that person mailed the toy to Dr. Zhang!

Could it be that there is some secret here?
"Well, officers, I have something else to do. Feel free to contact me if you need anything."

"Well, you go ahead."

"it is good."

After the man left, Lao Han hurriedly told his guess.

"Team leader, could he be that person?"

Luo Fei continued to look through the list and said, "Don't make a fuss. He doesn't look like a smart guy."

Old Han looked at Luo Fei's serious expression and thought he had heard it wrong.

It's already this late, why is Luo Fei still joking?
This is not a matter of similarity at all.

They have met so many suspects. Some of them are very good at acting and can deceive everyone temporarily. Only when there is solid evidence will they be willing to tell the truth.

Sometimes, people who don't look like suspects do things that are even more unexpected.

Until now, no one knows whether this young man is pretending to be kind and grateful. (End of this chapter)
