Originally, it was just a trivial matter, but when Gu Chen asked him like this, the manager felt that there must be something strange in it, so he hurriedly asked Gu Chen: "You mean...... The person who stole Ms. Liao's diamond ring is the one who owns this match?"

"That's pretty much what it means, but I need to look into it further, so ......"

Gu Chen looked at the manager and said, "So please be sure to cooperate with the manager." ”

"That's easy to say, I'll ask someone. The manager also immediately took out his mobile phone and hurriedly said: "This matter was sent by a person in charge of logistics, I will know if I ask him." ”

Everyone seemed to have found a cat greasy from a small match, but suddenly they felt that they couldn't find any clues with just a small match.

But Gu Chen is different......

He held the match as if he had found a treasure.

With specialized-level observation, the items found can draw inferences from one another.

Gu Chen currently has this kind of consideration, the key is that this match is a little special, but as for whether it is the same as his guess, he still needs to make a final judgment after investigating the scope of the suspect, so Gu Chen can't say it now.

After some communication, the manager hung up the phone and said: "Comrade policeman, the person in charge of logistics said that he has only given this kind of match to three people in total. ”

"Which three people?" Gu Chen asked.

"A doorman old man, another is a cleaning aunt who sweeps the floor, and another is a gardener in the scenic spot. So said the manager.

Gu Chen frowned, and asked again, "Then among these three people, has anyone ever raised birds?"

"Huh?" was also asked by Gu Chen, the manager looked at him in surprise and said, "How do you know that someone raises birds?"

"Yes, Senior Brother Gu. Seeing this, Lu Weiwei hurriedly asked him: "How do you know that some of these people raise birds?"

"Because of this. Gu Chen took the match in his hand and said, "In the middle of the match, you can find by yourself that there is a small groove here, and there are obvious traces of bites on the matchstick." ”

"So......" Officer Wang frowned.

So I concluded that the thief must have had experience in training birds, and he trained birds to steal, but in order to prevent birds from making a noise before stealing the ring, he would train birds to drop a matchstick in their mouths. ”

"My goodness. Don't be taken aback by Gu Chen's words, Lu Weiwei was directly dumbfounded: "Senior Brother Gu, where did you know all this?"

Gu Chen said with a smile: "Because I went on a trip with my family before, I saw someone who specially trained parrots and took advantage of the moment when tourists took out money. ”

"And these parrots pick out large bills, and for every 100-dollar bill they take, they get a certain amount of food reward, which is specially trained. ”

also heard Gu Chen say this, and everyone present suddenly realized that animals could still be trained like this.

"Sure enough, being well-informed is different. The manager couldn't help but be amazed: "Don't you say, there is a gardener in our scenic spot, he is not only quite accomplished in flowers, but also has a lot of research on birds, and he has a few parrots where he lives." ”

"What's his name?" Gu Chen saw that there was really such a person in the scenic area, so he hurriedly asked.

"Ari, we all call him Ari. ”

As soon as the manager's voice fell, Lu Weiwei and Officer Wang directly said a slump.

The manager was startled and hurriedly asked, "What's wrong?"

"This guy sits at the same table with us. Lu Weiwei said.

"I didn't expect this guy to be an all-rounder. Officer Wang also felt incredible.

I originally thought that such a thief was far away from me, but now it seems that it is better to meet by chance than to meet each other.

Gu Chen said: "Ah Rui should still be in the reception hall, and the diamond ring must still be on him." ”

"Then what are you waiting for?" the manager couldn't wait anyway, he hurriedly instructed the security guards around him: "You guys hurry over and catch this guy Ari to the monitoring room, I need to know if he has any stolen goods on him." ”

"Yes. Several security guards nodded and immediately walked towards the reception hall.

At this time, the manager said again: "A few police officers, let's go directly to the monitoring room, and I will also inform Ms. Liao, let's interrogate this Ari over there." ”

Gu Chen didn't speak, just nodded silently.

After all, this is just his own reasonable reasoning, whether the thief is Ari or not, it's hard to say, everything has to be result-oriented.

A few minutes later.

Gu Chen, Lu Weiwei and Officer Wang, along with Ms. Liao and the manager, have been waiting in the monitoring room for a long time.

It was also when they saw several security guards pushing and dragging Ah Rui to the monitoring room, and everyone stopped talking.

"Let go of me, you let go of me. Ah Rui struggled to break free from the hands of several security guards, and when he saw Gu Chen, Lu Weiwei and Officer Wang present, he was also stunned for a moment, and hurriedly asked, "Why are you here?"

"I'm waiting for you. Lu Weiwei said.

"Wait for me?" Ari became more and more confused the more he listened, scratching his head and puzzled, "What are you waiting for me to do?"

"Wait until you hand over Ms. Liao's ring. Officer Wang said.

At this time, Ah Rui was really stunned, especially after seeing Gu Chen's sharp eyes, the whole person couldn't help but take two steps back, and hurriedly said, "You...... Who the hell are you?"

Gu Chen took out his police ID: "I am a policeman from the Third Criminal Investigation Group of the Furong Branch, my name is Gu Chen." ”

Lu Weiwei and Officer Wang also took out their police cards in accordance with the process.

"I'll go, you...... Are you policemen?" It was only now that I realized that the few people sitting at the table with me just now were all policemen, and Ari was a little flustered.

But after calming down, Ari said again: "But, why did you bring me here? What do you mean by bringing me here?"

"They say my diamond ring is on you. Ms. Liao, who was a little anxious, opened her mouth directly.

"Diamond ring, on me?" Ari was stunned for a moment, and laughed out loud: "It's really funny, are you guys joking?"

He glanced at Gu Chen and said, "I said Brother Gu, oh no, it's Officer Gu, aren't you eating with me? I just went to the toilet, and you said I stole the diamond ring? This is probably the best joke I've heard this year." ”

Before he finished speaking, the white-haired security guard instantly pulled back his hand and took out a diamond ring from Ari's pocket: "What is this?"

I was most afraid that the air would suddenly be quiet, and Ah Rui's face turned pale with embarrassment in an instant.

And Ms. Liao, who was on the side, also exclaimed: "That...... That's my diamond ring, really my diamond ring. ”

After speaking, he snatched it in his hand, put it on his finger and said: "You see, this is the expensive diamond ring I said, or is it a gift from my husband on my birthday, it can't be wrong, there is also the English letter of my name in it, this is from the handwriting of the top European masters......"

Ms. Liao said a lot of things excitedly, all of which were to show off the nobility of her ring.

But that's not the point, the point is that the stolen goods were actually taken out of Are's pocket.

Not only was Ah Rui dumbfounded, but even Officer Wang was equally dumbfounded.

Just now, I was worried that Ari would transfer the diamond ring and hide it in a secret place.

But it's obviously an overestimation of this guy's IQ level......

This guy obviously thinks that even if he wants to investigate, it is impossible to find himself in a haystack in the crowd of people at the scene.

But after a while, he was taken to the monitoring room by the security guards of Moore Manor, and found the stolen goods from his pockets that he had stored at random.

"Everyone has stolen money. Gu Chen never thought that the case would be handled so easily, so he asked again: "There was a case of theft of a diamond ring last month, it should have been done by you, right?"

"It's not. Ah Rui was instantly dumbfounded, and tried his best to quibble: "Ms. Liao said that her diamond ring was stolen in the guest room, and I don't have the key, and Ms. Liao also locks the room, how can I get in? ”

"You can't get in, but your bird can fly in. Gu Chen's words exposed Ah Rui's lies.

Ari smiled bitterly twice, and said weakly, "Bird, why do you say it's a bird?"

"That's it. Gu Chen took the matchstick wrapped in a napkin in his hand and said, "This is what we picked up in the lawn under the windowsill of Ms. Liao's guest room, do you see a small groove in the middle of the matchstick?"

"That'...... What does that mean?" said Ari.

"Because this small groove is what your trained parrot uses its beak to hold, you put a small match in the parrot's mouth to prevent the parrot from accidentally making a noise during the theft mission. ”

"This kind of trick, I saw it a few years ago, so I was impressed. ”

"No, it's definitely not what you said, and I didn't let my parrot do this kind of stealing, you are completely setting the blame. ”

"What happened to the diamond ring that was found on you?" Gu Chen said that Ah Rui was stupid again.

Lu Weiwei also smiled and said: "Everyone has stolen money, you still want to quibble? Don't you know that we can extract animal DNA on matchsticks, and if it matches the parrot you raised, then you are at a loss for words?"

"Besides, why is Ms. Liao's diamond ring not on someone else, but on you? Are you stupid to be our policeman? You took advantage of the break between going to the toilet to actually go to the parrots you trained and search those guest rooms. ”

"What else do you have to say about directing the parrots to commit thefts as soon as they find valuables?

Officer Wang also immediately answered: "Ah Rui, you have long been familiar with this kind of industry reception, you know that the people who came to the scene today are some people with considerable status and status, so they are also quite interested in the guest room they are staying in." ”

"You want to use the convenience of your own bird raising to train the birds to steal, and it seems like you don't know it, but you ignore these little details. ”

"You didn't clean the matchsticks at the scene, do you think we won't be able to find them? You know, this kind of matchsticks that were eliminated by Moore Manor, the logistics director has only given them to three people in total, and we can find you with our toes. ”

"I advise you to confess and confess honestly, as well as the diamond ring that was stolen last time, you also hand it over to me, otherwise you know the seriousness of the consequences. ”

"This ring alone is enough for you to commit grand theft......"

also listened to Officer Wang's repeated warnings, Ah Rui was instantly dumbfounded, and the whole person suddenly squatted on the ground softly, regretting it: "I was wrong, I ...... I don't dare anymore, please give me a chance to be a new person. ”

"What about the ring you stole last month?" Gu Chen asked.

"In ...... In my dorm room, I haven't had time to make a move. Ari said.

Seeing that the police had cracked the theft case together with last month, the manager of Moore Manor was suddenly overjoyed and hurriedly said: "It turns out that the person who stole the diamond ring last month was also you, you are a good Ari, I am really blind if you don't learn to learn to steal things, and I asked you to come to the industry cocktail party." ”

"For people like you, I look down on you very much, I originally thought you were very smart, and I wanted to propose to the supervisor in the future to let you follow me to do it, but I didn't expect you to do this kind of thing, it's a shame on our Moore Manor people, I'm bah!"

also saw that Ah Rui, who he was more optimistic about, turned out to be the mastermind of these thefts, and the manager was also angry.

If it weren't for the presence of the police, the manager would have rushed up and given him a few kicks.

Gu Chen also smiled, looked at Lu Weiwei and Officer Wang, and said, "Why don't you ...... Let's get the diamond ring back and return it to the owner in time?"

"Good idea. Lu Weiwei felt happy in her heart, she had come to attend an industry cocktail party, and she was able to solve a theft case here.

also cracked last month's unsolved case.

Of course, this also has something to do with the fact that the lady who stole the theft did not choose to report the crime.

Ah Rui saw that these local tyrant elites were so indifferent to money, so they became more and more bold.

But this time he stole Ms. Liao's expensive diamond ring, so he fell into Gu Chen's hands, and he also admitted it, only blaming himself for not knowing the true identities of the three people at the same table.

Subsequently, under the leadership of Ah Rui, Gu Chen, Lu Weiwei and Officer Wang found the ring stolen last month under the bed in his dormitory.

Together with the three parrots that were thieves, they were brought back to the Seremban Branch.

Four o'clock in the afternoon.

After completing the recording of Ari's case, the parrot was taken to the animal rescue center by the relevant departments for temporary custody.

Gu Chen took the ring that had been lost in Moore Manor last month and called the manager of Moore Manor.

The call was quickly connected.

"May I ask if it's Officer Gu, right?" The manager on the other end of the phone obviously knew that it was Gu Chen.

"Manager, has the lady who lost her ring last month been contacted?" asked Gu Chen.

The manager was a little embarrassed and said: "It's strange to say, we've been practicing, but the phone just can't get through, and I don't know what happened to that lady?"

That is to say...... Haven't been contacted yet?" Gu Chen asked again.

"Huh. The other end of the phone also laughed dryly, and the manager said: "Otherwise, Officer Gu, what about the diamond ring, your criminal investigation team 3 will help keep it temporarily, what about the lady, I will continue to contact, if you get in touch, I will notify you immediately, do you see it?"

The manager said so, and Gu Chen couldn't refuse, so he could only promise stubbornly: "That's okay, that's the only way." ”

"Okay, then thank you, Officer Gu. ”

"Small meaning. ”

After a few brief pleasantries between the two, they hung up the phone with each other.

Lu Weiwei ate the potato chips, turned her head and asked, "What's the matter?

Gu Chen nodded.

Lu Weiwei said again: "These days, rich people don't even care about the loss of diamond rings, how rich is this?"

Gu Chen said with a smile: "People who don't have money, lose a bicycle, or a hundred-yuan bill, they may be depressed for a long time, because this may be their income for nearly a day." ”

"But rich people, like this kind of diamond ring, may not know how many there are at home, so they don't care. ”

"But as the people's police, we have the responsibility and obligation to return the stolen goods to their original owners, because we are policemen. ”

"Hee-hee. Seeing that Gu Chen was serious, Lu Weiwei couldn't help laughing and said, "Senior Brother Gu, you are becoming more and more like Zhao Ju, and Zhao Ju likes to talk like you." ”

"Is there one?" Gu Chen also smiled, not realizing that he had any similarities with Zhao Guozhi.

At this time, Yuan Shasha also put down the work in her hand, leaned on the desk and asked Gu Chen: "Senior Brother Gu, are the parrots you met today really so powerful?"

"Of course. Gu Chen also nodded and said: "These are specially trained parrots, such as this Ari, he trains parrots to steal through constant behavioral stimulation." ”

"Is the parrot so easy to train?" Yuan Shasha asked again.

Gu Chen also thought about it, and said, "Let's see how to train, in fact, it is using conditioned reflexes." ”

"Conditioned reflex?" Lu Weiwei was also unconscious, and hurriedly asked Gu Chen: "How can this use conditioned reflex to train?"

Seeing that Lu Weiwei was not too clear, Gu Chen also smiled and said: "It is a stimulus that cannot cause a certain reaction, and by giving this stimulus at the same time as another stimulus that can cause a reaction, they can establish a connection with each other." ”

Thus establishing a connection between the conditioned stimulus and the unconditioned response is called conditioning. ”

Seeing Lu Weiwei's understanding of the theory of conditioned reflexes, Gu Chen said: "The most common conditioned reflex is the food saliva secretion conditioned reflex. ”

"For example, before feeding the dog, the bell is ringed, and over time, when the paparazzi hear the truth of the bell, they will produce saliva, which is a conditioned reflex, and the bell is called a signal stimulus or conditioned stimulus. ”

"And we often use conditioned reflexes to train animals to master a certain skill and perform activities such as acting. ”

"I know. Yuan Shasha immediately raised her hand and said: "For example, sea lions top balls, dolphin performances and the like, as well as monkey play." ”

"Yes. Gu Chen also agreed: "However, this may also be used by criminals to teach animals to commit some kind of crime." ”

"For example, these parrots stealing, and monkeys stealing from small holes. ”

"It's very difficult to solve this kind of case if you don't find key evidence, and after the detection is solved, the animal is not guilty, but the person who trains the animal will be punished by the law, and Ari is the best example. ”
