Chapter 661

On the phone, Anna said with a dry smile: "those two cigarette butts we take to do the test, are indeed the same person."

"And after technical identification, blood group B, salivary epithelial cells, containing x, y two chromosomes."

"Good." Hearing such a reply, Gu Chen is somewhat relieved.

At least the technical problems have been solved by the Italian police.

So Gu Chen asked, "has the last contact with William been found?"

"This It's a bit of a problem. " Anna also told the truth and looked exhausted.

"Gu Chen, we have been investigating today. We can initially lock in. There are four people who have been to William's house. We are now preparing to summon these people. So I took the time to call you before the operation. I was afraid that you would be in a hurry."

Anna for Gu Chen's trust, is obviously quite at ease.

Explaining the operation to Gu Chen clearly goes beyond the content of the white paper in the Sino Italian police cooperation.

According to the white paper, in fact, the Italian police do not need to notify.

But Anna also took into account that the situation of William was first discovered by Gu Chen's Chinese police team.

Don't talk to Gu Chen, it seems a little too mean.

Therefore, after weighing, Anna still chooses to inform Gu Chen.

"Thank you, Anna." Gu Chen has already felt the pressure from Anna's words, so he said with a smile: "can you give me a general idea of who these people are?"

"One is a mason." Anna said faintly: "the house of William's house was damaged, so the bricklayer who had been appointed last night came to repair it. These neighbors can testify, because the mason was introduced by the neighbor."

Anna was saying that Gu Chen was already taking notes and asked, "what about the others?"

"The second is a beggar." Anna continued: "last night, a famous beggar had been begging from door to door. William sent some food out of the house, which was clear to the neighbors."

"And the third one is William's William's lover, she also went to William's house last night. We confirmed all these on the phone

"As for the last one, it was a salesman who came to sell the product, but William didn't buy it."

"These are the four most likely suspects that we have finally identified based on the call records and the visits of our neighbors."

Anna has just finished and Gu Chen has recorded all the clues.

There was a brief silence on the phone.

Anna was puzzled and asked Gu Chen, "Gu Chen, are you listening?"

"I'm here." Gu Chen said.

"If there's nothing else, we might have to check these people." Anna said weakly, trying to wait for Gu Chen's response.

After a brief pause of two seconds, Gu Chen said: "Anna, you should pay attention to this Mason. This man is very suspicious."

"What? Are you saying that a Mason is most likely? " Anna's whole person was stunned. She also said with a smile: "Gu Chen, we haven't investigated these four people. How can you just let us focus on the Mason?"

"Because he's a big suspect." Gu Chen is not afraid to express his ideas.

This makes Anna on the other end of the phone stunned.

After hearing the conversation, officer Wang couldn't help but wonder: "Gu Chen, this Anna police officer clearly told you that there are four suspects. Why are you only interested in the Mason? Do you suspect that Mr. William's death has something to do with him

"Yes." Gu Chen nodded to officer Wang and said to the phone, "officer Anna, you can do as I say. First, investigate the mason."

"Why?" Anna hesitated, instinctively repelled: "Gu Chen, you know, the investigation takes time, but you have to give me a reason?"

Although she knows Gu Chen's quick thinking, Anna sometimes really can't keep up with Gu Chen's rhythm.

From the partner career these days, we can see that there is an obvious gap between the efficiency of handling cases between ourselves and the Chinese police.

In particular, the Chinese police can always give the most appropriate option, which makes Anna a little embarrassed.

"Anna." Gu Chen saw Anna hesitated and turned her pen habitually with her right hand. She circled the four suspects on the paper and said, "you know, these suspects all went to William's house last night, and they are the most likely killers to kill William."

"Therefore, you should combine the characteristics of these people to accurately investigate and give priority to filtering out the suspects with the lowest probability. In this way, your work efficiency will be greatly improved."

"I'll just say a few points. I'll ask you, did I ever find cigarette ends in the house?"

"Yes Yes, you told me personally that one cigarette end is in the room and the other is on the doorstep

"That's right." Gu Chen nodded positively and explained, "this man can enter the house, talk to William, and have a cigarette in his mouth. Do you think it is possible for a beggar?"Gu Chen asked, but let Anna sober up.

After a moment's hesitation, Anna said, "yes, beggars come to beg for food, and they still have cigarettes in their mouth, and one or two cigarettes, which is a bit unreasonable."

"If beggars have money to buy cigarettes, they don't have to beg, so the probability of beggars who can enter the house should be very low."

"So salesmen can be eliminated quickly." Gu Chen took his mobile phone, walked back and forth in the room and said, "have you found the brand of cigarette?"

"Low end cigarettes, as I said before at William's house, are the cheapest cigarettes of a low-end brand in Italy." Anna said.

"Yes." Gu Chen was very sure: "you mentioned it to me before. Later, I also searched for relevant information according to the cigarette logo. I found that this kind of cigarette can be called a national affordable cigarette."

"This kind of smoke is especially popular among low-income people, so it shows that the perpetrator is probably not rich and doesn't care what others think of him."

"If that's the case, you can exclude the salesman, because the salesman is the most concerned about others' impression of himself."

"No matter how poor you are, you can at least get a decent cigarette. Even if it's not a high-end product, it's not the cheapest low-grade cigarette."

"Yes." Listening to Gu Chen's words, Anna at the other end of the phone said happily: "guchen, what you said is very reasonable. If I were a salesman, I would not be able to take out low-cost cigarettes in front of William, a rich man, and even smoke two cigarettes. Obviously, it is not consistent with the professional habit of promoting sales."

"What's more, salesmen are most concerned about face, which can be eliminated only from the aspect of image."

"And your tests." Gu Chen followed Anna's words and said, "if I heard you correctly, you just told me that epithelial cells were detected from cigarette ends, right?"

"Yes." Anna's on the test right now: "I agree with it."

"Epithelial cells have X and Y chromosomes, right?" Gu Chen confirmed.

Anna said with a smile: "yes, is there a problem?"

"Of course there is a problem, because at least it can be said that the perpetrator is a man, so William's lover can be ruled out." Gu Chen said.

"So?" Anna's whole body was shocked. She was stunned. Then she said, "before, I was not very familiar with epithelial cells and chromosomes. It turns out that there is such a saying. Through chromosomes, men and women can be distinguished."

"This is the basic knowledge. We learned biology in high school." Gu Chen chuckled twice, and then he said again:

"Anna, you just have to remember that men and women have different sex chromosomes. Men are made up of XY, and women are made up of XX."

"So to do a blood test, is to check whether there is y sex chromosome, if so, it is male."

"So it is?" Anna once again admired Gu Chen, and the whole person couldn't help exclaiming, "Gu Chen, you're really great."

"According to your distinction, the smoker must be male, and William's lover can be excluded. You are a genius."

Anna for Gu Chen's talent, that is in the heart of admiration.

In this way, Gu Chen can actually use the exclusion method to help him find out the most likely suspect.

Think about yourself just now, and I'm going to follow my colleagues to investigate the four suspects.

You know, the work of investigating a suspect is quite long and tedious.

It is even more difficult to investigate four suspects at the same time. Sometimes it is more like looking for a needle in a haystack.

Not to mention the time cost, the various resources consumed are also numerous.

Thinking of this, Anna was very excited and asked Gu Chen, "according to what you said, the first three can be excluded, only the Mason is the most suitable?"

"That's right." Gu Chen is also not stingy to share: "you think, those two low-end cigarettes, cigarette butts are not very short?"

"Yes Yes

Gu Chen hears the phone, there is the movement of looking through the paper, obviously, Anna is also looking up the information.

"The cigarette end is very short, soaked in saliva, indicating that the perpetrator habitually held the cigarette end in his mouth."

"Most of us don't put a cigarette holder in our mouth. Unless the hands are dirty or too busy to make a move, then the Mason is in line with this characteristic."

"To sum up, the Mason is the most suspect. You can start with him first."

"Ha ha, can you be so relaxed?" Anna was so happy that she didn't know how to praise Gu Chen.

Gu Chen's simple reasoning has helped to eliminate three people according to the known clues.

In this way, Anna's Italian police, there will be the main investigation object, the heart can not be happy.

"Thank you Gu Chen. If there is any progress in the case, I will keep you informed..."Anna hung up in a thank-you.

On the other hand, the whole process of officer Wang, did not surprise Gu Chen's quick reasoning.

Such operations, officer Wang seems to be used to.

Just kindly reminded: "Gu Chen, you help Italian police without reservation, they do not see them to appreciate, at noon Cameron things you forgot? I would say, it's better for them to solve it themselves, or see how efficient they are. "

"Brother Wang." Gu Chen glanced back at him and said, "maybe Italian police can do well. I just speed up their procedure."

"You know, if four suspects are investigated at the same time, the police resources and time spent are immeasurable."

"And once the time is too long, it will hinder the progress of the case. The fastest time and the most accurate key to help them find out the problem is just helping us ourselves."

"Because William, although meeting us by chance, is also a friend and a simple understanding. I also hope to find out who the killer is as soon as possible."

Gu Chen's work, there is no so-called collusion, the agency calculation.

Even if there are contradictions and exclusions in the process of handling cases, they only need to solve the key problems.

Sometimes it doesn't take into account other

Officer Wang also knew Gu Chen's temper, so he did not refute, put his hand and said, "don't think anything, wash and sleep."

……

……

The next morning.

As usual, Anna drove to pick up the Chinese police team to the police station.

On the way, Anna briefly introduced the progress of the team members' investigation.

Since last night, Italian police have taken action, and the operation is still in progress.

Come to the police office in Luocheng.

Mario saw Gu Chen just sitting down, and he personally handed a cup of hot milk to Gu Chen and said, "officer Gu, this milk is for you."

"Thank you. I've had it in the hotel." Gu Chen refused.

Mario was a little bit unhappy and said directly: "this is not the same. This milk is for all my colleagues in our office. I thank you for your good morning."

"Thank you?" Gu Chen was stunned and asked him curiously, "officer Mario, what do you thank me for no reason?"

"He would like to thank you for finding out for us the most likely murderer to strangle William." Anna put down her objects and walked to Gu Chen and said, "do you know Gu Chen? The idea of handling the case you gave us yesterday is enough to reduce a lot of work. "

"Just investigating that Mason is enough to make us headache, and as you might guess, we also think the Mason has a problem."

"Have you found any recent results?" Gu Chen was curious and asked again.

Mario shrugged and laughed, "it's too early for George to take people to search. I think it's soon to get the mason."

"I wish." Gu Chen nodded slightly, looked at the hot pure milk on the table, and he could not smile and hold it in his hand, saying, "that line, I drink this milk."

Said this, Gu Chen raised his right hand, and drank the milk in the cup.

"That's right." Mario, like good friends, put his fat right hand on Gu Chen's shoulder and said, "Gu Chen, you think it's a good policeman. We all think so."

"Yes."

"Yes."

"Gu Chen, I did pretty."

……

Led by officer Mario, many Italian police officers in the office issued friendly comments.

This also objectively speaking, everyone to Gu Chen recognition has further enhanced a step.

Gu Chen smiled and stood up and saluted, "thank you for your recognition. We are friends. The police of both countries help each other. That is right."

"Guchen." "I also met Gu Chen politely, sitting behind Gu Chen, Fabio joked:" are you so clever, are you a child parents have carried out special interest and hobby training for you? "

"I remember your parents, as if they were young, like to ask you to report some interest classes and so on. I wonder if it is?"

"Yeah, Gu Chen should have developed intelligence when he was a child, right? Otherwise, your ability to respond and reason can always be faster than us. In the previous cases, not only you, but also your whole Chinese police team will respond faster than us. "

Anna has a lot of opinion on this.

After all, last time, luweiwei actually became a teacher, and carefully sorted out the case to Italian police.

It was precisely because of that beginning that we could not underestimate the strength of the Chinese police team.

Gu Chen looked at the curious eyes of everyone, but also joked: "in our country, what parents like is interest and hobby, what parents don't like, that is to say, it is called" desperation ""So what you call interest actually depends on the parents. For example, if you fall in love, if your parents agree to love, that's love. If your parents don't agree, it's called cheating."

"Pooh ha ha ha!" Listening to Gu Chen's humorous remarks, many Italian police officers in the office were amused.

This is the first time that we have heard of this

"Ha ha, Gu Chen." Anna also calmed down her mood and said with a dry smile: "if that's the case, I think the worst place for a parent is that you look down on your children, and you want your children to become dragons and phoenixes. How can you make your children's feelings worse?"

"It's also the biggest failure." Gu Chen accepted Anna's comments and said, "so whenever our Chinese children develop some hobbies, they will say," can this be used as food? "

"And when our Chinese children really take this as an interest, they will say that they know to eat all day long."

"Ha ha..."

Hearing this, many Italian police are already whispering and laughing. It seems that Gu Chen's self mocking things are very fresh and interesting to everyone.

"Isn't that limiting your development?" An Italian policeman raised his hand and asked Gu Chen.

Gu Chen looked back at him and said with a smile, "you are right. In fact, the times are different now. There is an old saying in our country, which is called" 360 lines, and the number one scholar comes from every line. "

"In fact, parents should not always limit their children's future eating problems to iron rice bowls."

Pointing to himself, Gu Chen said: "my parents belong to this majority. Their understanding of iron rice bowl is to eat in one place for a lifetime."

"In my opinion, in fact, the real iron rice bowl is not to eat in one place for a lifetime, but to have food everywhere for a lifetime."

"Therefore, as a people's police officer, what I have to do is to constantly polish and improve my skills to help more people in need. "

" when you really do these things to serve the people well, you won't lose your job. At that time, the iron rice bowl will become the golden rice bowl, and it will be more delicious to eat with it. "

"Ha ha ha..."

There was another burst of laughter in the office.

At first, everyone thought Gu Chen was a serious school, but when he talked about the truth, he was also a powerful one.

As for Gu Chen, he is very popular with the national police.

At the same time, Mario suddenly looked at the latest pictures from the computer and said with a smile, "look, it's George who got the image of the mason."

With officer Mario's eyes, Gu Chen also quickly turned to look.

But when he saw the head picture suddenly flashed on the screen, Gu Chen's whole person suddenly froze, momentarily froze there.

"Why What's the matter, Gu Chen? " Anna looked at him puzzled.

"How could it be him?" Gu Chen looked back at Anna and said, "you and I know this Mason."
