I am a super cop

Chapter 460 Conditional Reflex

It was originally just a trivial matter, but when Gu Chen asked him this question, the manager felt that something was wrong, so he quickly asked Gu Chen, "You mean... the person who stole Ms. Liao's diamond ring is the one who owns this kind of match." ?”

"That's almost what it means, but I still need to investigate further, so..."

Gu Chen looked at the manager and said again: "So please cooperate with the manager."

"It's easy to say, I'll ask someone to ask." 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 ask him and he will know."

Everyone seemed to have found something tricky from a small match, but suddenly felt that there seemed to be no clues at all with only a small match.

But Gu Chen is different...

Holding this match, he seemed to be picking up a treasure.

Possesses a specialized level of observation, and can draw inferences about the items discovered.

Gu Chen has this kind of consideration at present, the key is that this match is a bit special, but as to whether it is the same as what he guessed, the final judgment can only be made after investigating the scope of the suspect, so it is hard for Gu Chen to say now. .

After some communication, the manager hung up the phone and said, "Comrade police, the person in charge of logistics said that he only gave this kind of matches to three people."

"Which three people?" Gu Chen asked.

"There is an old man who is a doorman, another is a cleaning lady who sweeps the floor, and the other is a gardener in a scenic spot." The manager said truthfully.

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 keeps birds?"

"Yes, Junior 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 held the match in his hand, and said, "In the middle of the match, you can observe for yourself that there is a small groove here, and there are obvious marks of biting on the matchstick."

"So..." Officer Wang frowned.

"So I concluded that the thief must have experience in training birds. He trained birds to steal things, but in order to prevent the birds from making any noise before stealing the diamond ring, he would train the birds to drop a matchstick from their beaks."

"My dear." Not to be surprised by Gu Chen's words, Lu Weiwei said dumbfoundedly: "Junior 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 specially training parrots, taking advantage of the moment when tourists took out money, and took the banknotes away."

"And these parrots specialize in picking large bills, and they can get a certain amount of food rewards every time they pick up a hundred-yuan bill. These are specially trained by someone."

Hearing what Gu Chen said, everyone present suddenly realized that animals can still be trained like this.

"Sure enough, it's different to be well-informed." The manager couldn't help but wondered: "Don't tell me, there is a gardener in our scenic spot. He is not only knowledgeable in flowers, but also has a lot of research on birds. He lives in the Raised a few parrots."

"What's his name?" Seeing that there was such a person in the scenic spot, Gu Chen hurriedly asked.

"Ari, we all call him Ari."

As soon as the manager finished speaking, Lu Weiwei and Police Officer Wang just said shit.

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

"This guy is sitting at our table." Lu Weiwei said.

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

At first, I 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 again.

Gu Chen said: "Ari 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 any longer. He hurriedly told the security guards beside him, "You guys hurry up and take this guy A Rui 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: "Several police officers, let's go directly to the monitoring room, and I will also notify Ms. Liao, let's interrogate this Ari over there together."

Gu Chen didn't speak, just nodded silently.

After all, this is just my own reasonable reasoning. It's hard to say whether the thief is Ari, and everything is result-oriented.

After a few minutes.

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

It was also after seeing several security guards pushing and dragging Ari to the monitoring room, everyone stopped discussing.

"Let me go, let me go." Ari struggled and broke free from the grasp of several security guards. When he saw Gu Chen, Lu Weiwei and Police Officer Wang present, he was taken aback for a moment, and quickly asked, "Why are you here?" ?”

"Wait for you." Lu Weiwei said.

"Wait for me?" A Rui became more confused as he listened, scratching his head in confusion, "What are you waiting for me for?"

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

Ah Rui was really confused now, especially after seeing Gu Chen's sharp eyes, he couldn't help but take two steps back, and hurriedly said, "You... who are you guys?"

Gu Chen took out his police ID: "I'm a policeman from the Criminal Investigation Group [-] of the Furong Sub-bureau, and my name is Gu Chen."

Lu Weiwei and Officer Wang also followed the procedure and took out their police cards.

"I'm going, you... are you the police?" It was only now that he realized that the people sitting at the table with him were all police officers, so Ari panicked.

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

"They said that my diamond ring is on you." Ms. Liao, who was a little anxious, said directly.

"Diamond ring? On me?" Ari was stunned for a moment, but also laughed loudly: "It's really interesting, are you guys joking?"

He glanced at Gu Chen and said, "I said Brother Gu, oh no, it's Police Officer Gu, aren't you eating with me? I just went to the bathroom, and you all said I stole the diamond ring? It's possible Best joke I've heard this year."

Before he could finish speaking, the white-haired security guard immediately pulled out a diamond ring from A Rui's pocket: "What is this?"

Most afraid of the sudden silence of the air, A Rui's face turned pale with embarrassment.

And Ms. Liao at the side also screamed: "That... that is my diamond ring, it is really my diamond ring."

After speaking, he grabbed it in his hand, put it on his finger and said: "Look, this is the expensive diamond ring I mentioned, and it was a gift from my husband on my birthday. It can't be wrong. , and there are English letters of my name in it, which are written by top European masters..."

Ms. Liao said a lot 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 indeed taken out of Ari's pocket.

Now not only Ari was dumbfounded, but even police officer Wang was also dumbfounded.

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

But obviously overestimated the IQ level of this guy...

This guy obviously thought that even if he wanted to investigate, it would be impossible to find him like a needle in a haystack among the crowd at the reception.

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 casually stored pockets.

"Everyone gets the stolen goods." Gu Chen never thought that handling the case would be so easy, so he asked again: "There was a diamond ring theft case last month, you should have done it too, right?"

"No." Ari was dumbfounded for a moment, and tried to argue: "Ms. Liao said that her diamond ring was stolen in the guest room. I don't have the key, and Ms. Liao also has a locked room. How could I get in?" ? You are slandering."

"You can't get in, but your birds can fly in." Gu Chen exposed A Rui's lie.

A Rui smiled bitterly, and said weakly: "Bird? Why do you call it a bird?"

"That's all." Gu Chen took the matchstick wrapped in a napkin and said, "We found this on the lawn under the window sill of Ms. Liao's room. Did you see the groove?"

"Then... what does that mean?" Ari said.

"Because this small groove is the shape of the parrot you trained with its mouth. In order to prevent the parrot from accidentally making a movement during the stealing task, you put a small match in the parrot's mouth."

"I saw this kind of trick a few years ago, so I was very impressed."

"No, it's definitely not what you said. I didn't let my parrot do such a thing of theft. You guys are totally planting the blame."

"Then what happened to the diamond ring that was found on your body?" Gu Chen asked A Rui again.

Lu Weiwei also smiled and said: "Everyone has got the stolen goods, and you still want to quibble? Don't you know that we can extract the DNA of animals on matchsticks. If it matches the parrot you raise, how can you tell me?" Isn't it hard to argue?"

"Besides, why is Ms. Liao's diamond ring not on someone else's body, but on yours? Are you foolish to think that we are the police? You used the gap between going to the toilet to find the parrot you trained and search those guest rooms. "

"Once the valuables are found, you will order the parrot to carry out the theft. What else do you have to say? Do you want me to make it clearer?"

Police officer Wang also answered immediately: "Ari, you have long been familiar with this kind of industry reception. You know that the people who came to the scene today are all people of considerable status and status, so they are very concerned about the guest rooms where they stay. interested."

"You want to take advantage of the convenience of keeping your own birds and train them to steal, seemingly without anyone noticing, but you ignore these small details."

"You didn't clean up the matchsticks at the scene. Do you think we won't be able to find them? You know, the logistics supervisor only gave three people this kind of matches eliminated by Moore Manor. We can find you with our toes."

"I advise you to be honest and tell me the truth. You should also hand over the diamond ring that was stolen last time, otherwise you will know the seriousness of the consequences."

"Just this ring is enough for you to constitute major theft..."

Hearing Police Officer Wang's warning over and over again, A Rui was dumbfounded for a moment, and suddenly squatted limply on the ground, regretting endlessly: "I was wrong, I... I don't dare anymore, please give me a new one." An opportunity to be human."

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

"In...in my dormitory, I haven't had time to make a move yet." Ari said.

Seeing that the police and the theft case last month were solved together, the manager of the Moore Manor was overjoyed, and hurriedly said: "It turns out that you were the one who stole the diamond ring last month. Good luck, Ari. Don't learn if you're good. I was so blind that someone stole something, and I even asked you to come to the industry reception."

"I really despise you for a person like you. I thought you were very smart, and I wanted to propose to the supervisor in the future to let you work with me. I didn't expect you to do such a thing. It's a shame for us Moore Manor people." face, I pooh!"

Seeing that A Rui, who he was more optimistic about, turned out to be the mastermind of these thefts, the manager was also furious.

If it weren't for the presence of the police, the manager would have rushed to give him a few jios.

Gu Chen also smiled, looked at Lu Weiwei and Police Officer Wang, and said, "How about... let's take that diamond ring back and return it to the owner when we find time?"

"Good idea." Lu Weiwei felt elated. She was here to attend the industry reception, but she was able to solve a theft case here.

It also solved the unsolved case last month.

Of course, this is also related to the fact that the stolen lady did not choose to report the crime.

A Rui saw that these wealthy elites were so careless about money, so he became more and more courageous.

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

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

Together with the three parrots who were thieves, they were brought back to the Furong sub-bureau.

Four p.m.

After completing the collection of Ari's case, the parrot was taken to the Animal Rescue Center by relevant departments for temporary custody.

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

The call was quickly connected.

"Excuse me, is it Police Officer Gu?" The manager on the other end of the phone obviously knew it was Gu Chen.

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

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

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

"Hehe." The other end of the phone also laughed dryly, and the manager said again: "How about this? Officer Gu, the diamond ring, your Criminal Investigation Team [-] will help you temporarily keep it, and the lady on the other end, I will continue to contact you. It's up, I'll let you know right away, do you think it's okay?"

After the manager said so, Gu Chen couldn't refuse, so he could only bite the bullet and agree: "That's fine, it's the only way."

"Hey! Alright, then thank you, Officer Gu."

"Small idea."

After exchanging a few simple greetings, the two hung up the phone with each other.

After eating potato chips, Lu Weiwei turned her head and asked, "What's the matter? The owner hasn't been contacted?"

Gu Chen nodded.

Lu Weiwei said again: "These days, rich people don't even care about losing their diamond rings, how rich are they?"

Gu Chen smiled and said: "People who have no money may feel depressed for a long time if they lose a bicycle or a hundred yuan bill, because this may be their income for nearly a day."

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

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

"Hee hee." Seeing Gu Chen's seriousness, Lu Weiwei couldn't help laughing and said, "Junior Brother Gu, you are becoming more and more like Zhao Ju, and Zhao Ju likes to talk like you."

"Is there?" Gu Chen also smiled, but didn't find any similarities between himself and Zhao Guozhi.

At this time, Yuan Shasha also put down her work, 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, who 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: "Look at how to train, in fact, it is the use of conditioned reflex."

"Conditioned reflex?" Lu Weiwei didn't know what was going on, and hurriedly asked Gu Chen: "How do you use conditioned reflex to train?"

Seeing that Lu Weiwei was not very clear, Gu Chen also smiled and said: "It is a stimulus that cannot cause a certain reaction. By giving this stimulus and another stimulus that can cause a response at the same time, they are connected with each other."

"Thus establishing a connection between the conditioned stimulus and the unconditioned response, this is the conditioned reflex."

Seeing that Lu Weiwei had a little understanding of the theory of conditioned reflex, Gu Chen said again: "The most common conditioned reflex is the food saliva secretion conditioned reflex."

"It's like ringing the bell before feeding the dog. Over time, when the dog hears the bell, it will salivate. This is a conditioned reflex. Ringing the bell is called a signal stimulus or a conditioned stimulus."

"And we often use conditioned reflexes to train animals to master certain skills and perform activities such as performances."

"I know." Yuan Shasha immediately raised her hand and said, "Such as sea lions heading the ball, dolphin performances, and monkey tricks."

"Yes." Gu Chen also agreed: "However, this may also be used by criminals to teach animals to commit certain crimes."

"For example, the theft of these parrots, and the theft of monkeys entering the room through narrow holes."

"If this type of case does not find key evidence, it is difficult to solve the case. After the detection, the animal is not guilty, but the person who trains the animal will be punished by law. Ari is the best example."
