On the day when the Jiangbei police announced the closure of the case, the police stations of the major sub-bureaus received confidential documents from the internal police stations, which were then distributed to the major case-handling teams.

There is only one task, to shift the focus of the previous checkpoint inspection to the secret monitoring of the gold market.

The city bureau has asked all major criminal investigation teams to increase the city's gold market, especially gold on the black market.

As soon as it is discovered that someone is selling a large amount of gold, it is immediately closely monitored.

On the other hand, Gu Chen's exchange and study group of the Furong Branch of Jiangnan City, after studying and working in the Wutong Branch of Jiangbei for a week, will also embark on the return journey back to Jiangnan City.

2 p.m.

All the members of the exchange team who had lunch were packing their bags in the dormitory.

Everyone has a half-day holiday in the afternoon, and the time can be spent freely, so everyone decided to prepare to go shopping collectively, buy some Jiangbei specialties to take home, and send relatives to colleagues.

After Gu Chen finished packing his luggage early, he lay on the bed and rested for a while.

But at this moment, Gu Chen's mobile phone suddenly rang, and the call was from Elevation.

Gu Chen didn't think much about it, and directly connected the phone: "Senior Brother Gao." ”

"Gu Chen, we caught a man selling gold necklaces on the black market, and the amount is huge, we have contacted the management of the gold store in the high-tech zone, and they confirmed that these things are from that gold store. ”

After hearing this, Gu Chen sat up with a "whoosh": "Really caught?"

"Yes, the person has been caught, Gan Wenfeng and a few colleagues are taking him to the substation, there will be an interrogation later, will you come?"

Gao Cheng said very sincerely, which seemed to surprise Gu Chen.

This elevation, Gu Chen and him looked forward to it, and it seemed that he also felt that the elevation was a little cautious.

It stands to reason that they should not invite the police from Gangnam City to participate in the interrogation of suspects.

But what happened today? All of a sudden, you changed your mind?

Gu Chen asked curiously, "Senior Brother Gao, are you serious?"

"Of course it's serious, you have to come. Probably because of the tone problem, Gao Cheng realized that he was very urgent, so he quickly explained in a docile tone: "Hehe, Gu Chen, you didn't come up with this idea." ”

"Now that people have been caught, it stands to reason that you also have a share of the credit, but our bureau lied in front of many media a week ago, I'm afraid it's not easy to solve. ”

When Gu Chen heard this, he suddenly understood the purpose of elevation.

If the co-authorship is interrogated, a press conference will have to be held.

At that point, the media in Jiangbei will obviously feel that they have been tricked, even if the police solve the case?

Gao Cheng is so attentive, obviously he wants to make himself a scapegoat, and he went over to explain.

After all, Gu Chen is a policeman in Jiangnan City, and the Jiangbei media can't count Gu Chen's head, especially this idea, which was proposed by Gu Chen.

In this way, it seems that he took the initiative to share a little pressure on the head of the bureau, and it seems to be in the past.

"Okay, I'll take a look. After thinking about it, Gu Chen said again: "By the way, then Senior Brother Wang and Senior Sister Lu should be called over together?"

"No, there are not so many people in the interrogation room, just come here alone, Gan Wenfeng and I are waiting for you there." ”

After a few brief explanations, Gao Cheng hung up the phone.

Hearing that Officer Wang was next door, chatting with He Junchao and the others, Gu Chen didn't say hello, and went downstairs directly along the corridor, and then walked towards the interrogation room of the Wutong Branch.

In the No. 3 interrogation room of the Wutong Branch, Gu Chen had just arrived, and a middle-aged man with a fierce face happened to be brought in by Gan Wenfeng and sat on the opposite seat.

Gao Cheng closed the door of the interrogation room, then turned on the camera, urging Gu Chen: "Gu Chen, you find a place to sit down first." ”

"Good. Gu Chen looked at it and took the initiative to choose the seat on the far right to sit down first.

Immediately after, Gao Cheng sat in the middle, Gan Wenfeng sat on the left side, he took out the transcript and began to prepare the recording procedure.

"Give me your name, age, and ID number. Gan Wenfeng asked him coldly, without raising his head.

"I ......" The middle-aged man opposite was silent for a moment, and then said slowly: "My name is Wang Bing, 42 years old this year, and my ID number is ......."

The man named Wang Bing replied in a cold tone.

He was very quiet at the moment, and there was a hint of indifference in his eyes.

He didn't look at the three policemen opposite, and he didn't show any fear.

"Do you know why I caught you here?" said Elevation with his fingers crossed and asked him coldly.

Wang Bing shook his head: "I don't know." ”

"Then let me ask you, what is the matter with all that gold jewelry you trade on the black market?" asked Elevation again.

Wang Bing was silent again directly, and didn't say a word for a long time.

"Don't think you're okay if you don't talk. Gao Cheng obviously didn't eat this, he directly put a transparent forensic bag containing a large amount of gold jewelry on the table, and the "bell" sound made the atmosphere extremely weird.

"These things are all used by you to trade on the black market, we took stock of the stolen gold store in the high-tech zone, and the manager over there told me that these things were indeed lost from that store. ”

"Combined with the part we found in the deceased Zhang Xiaoya's house before, we just made up all the numbers. ”

"Wait a minute. Wang Bing suddenly interrupted Gao Cheng's questioning and said, "I picked up these things. ”

"Picked up?" was also amused by the story made up by Wang Bing, Gan Wenfeng smiled directly: "You can pick up this kind of thing?

"You might as well just say that it was given to you by a mermaid. Gao Cheng was also amused by Wang Bing's hypocrisy.

Wang Bing stared at Gao Cheng and Gan Wenfeng, and said coldly, "Are you laughing at me?"

"I'm sorry. Gan Wenfeng calmed down and continued: "We police officers are professionally trained, no matter how funny we are, we won't laugh unless we can't help it!"

"Poof!" Gao Cheng on the side, one didn't hold back, and directly laughed again.

The two men covered their mouths and forcibly controlled their emotions.

But Wang Bing seemed to have relaxed his vigilance and was directly ready to Erlang's legs.

And at this moment, Gao Cheng suddenly slapped the table, almost not scaring Wang Bing's soul, and the right jio who had just been raised was scared back again.

"Wang Bing, when are you going to pretend to be garlic? Don't think that the adhesive paper in Zhang Xiaoya's room doesn't have your fingerprints, and we can't find any evidence that you have been to Zhang Xiaoya's room. ”

Gao Cheng glanced at Gu Chen and said, "Gu Chen, you come and say." ”

"Good. "Gu Chen is better than obeying his fate.

Originally, he was also here to observe, and the recording and interrogation were all done by Gao Cheng and Gan Wenfeng, and he didn't think about speaking.

But Gu Chen had already prepared to open the chatterbox, but when the words came to his lips a few times, he stopped again.

After all, this is not their home turf......

Now Gao Cheng took the initiative to let Gu Chen come to him, obviously he also wanted to see the habits of the Jiangnan City police in handling cases.

Gu Chen stood up directly and walked towards Wang Bing.

In the interrogation of cases, especially the interrogation of suspects, Gu Chen has never liked to sit there in a proper manner, but to stand close to the suspect.

The seated suspect and the standing Gu Chen will form an upward and downward gaze in terms of vision.

Gu Chen gave the suspect a strong pressure with the height of his overhead and sharp eyes, making the suspect lose all his momentum in front of Gu Chen.

"Ahem!" Gu Chen coughed twice and directly pulled the vest on Wang Bing's body.

Wang Bing shrank back in fright, and hurriedly asked, "...... you What do you want to do?"

"Unbutton your shirt, now. Gu Chen said.

"For ...... Why?" Wang Bing was also stunned, a little nervous by Gu Chen's actions.

Gan Wenfeng, who was sitting on the interrogation seat, directly slapped the table angrily: "Wang Bing, let you untie it, don't talk nonsense, please cooperate with the police investigation." ”

Wang Bing's hands suddenly grabbed his shirt, and he didn't dare to move.

Gu Chen smiled and said, "You don't have to untie it for me to guess, there should be a few scratches on your chest, and the blood stains on the wound should have congealed, and now only the scar remains." ”

Wang Bing's eyes widened, and he shrank back with some fear.

"Don't look at me like that. Gu Chen smiled faintly and continued: "You originally arranged the house rented by Zhang Xiaoya into a secret room, which was indeed a bit redundant. ”

"It's okay to confuse ordinary people, but if you want to confuse the police, you're almost on fire. ”

"I admit that you are very smart, but sometimes you have to know that being smart is mistaken by being smart, if you kill Zhang Xiaoya, will Zhang Xiaoya stand there in vain, watching you commit murder?"

"You...... What the hell do you want to say?" Wang Bing's mood at the moment was also up and down, and he was completely out of order.

He looked at Gu Chen's sharp eyes, and he didn't dare to look at each other, so he could only turn his gaze to the side and ask Gu Chen why.

Gu Chen smiled and said, "The reason is very simple, at the same time as you stab Zhang Xiaoya, your chest or arm will definitely be painful Zhang Xiaoya's scratch and pain, and the strength of that pain will be several times that of usual, so there must be a wound on your body." ”

Gao Cheng listened to Gu Chen's words, and he immediately walked to Wang Bing's side and said, "Wang Bing, I order you to untie your shirt now, immediately, immediately." ”

Wang Bing was still hesitating, but Elevation warned again.

However, at this time, Gu Chen found that the back of Wang Bing's hand that was used to cover his chest had several deep scratches.

Gu Chen immediately grabbed his right hand, carefully observed Wang Bing's wound, and immediately smiled and said, "Where did your wound come from?"

"I ......" Wang Bing was speechless for a moment, but the two policemen were already standing in front of him, and he still replied in a low voice: "I fought with someone and was scratched." ”

"This person should be Zhang Xiaoya, right?" Gu Chen said.

Wang Bing hurriedly shook his head and refused to admit it: "No...... It's not Zhang Xiaoya, and I don't know Zhang Xiaoya at all. ”

"You're still quibbling until now. Gu Chen shook his head and continued: "I've given you a lot of opportunities, but you're still obsessed, so let me tell you." ”

"These injuries on the back of your hand were scratched by Zhang Xiaoya when you murdered Zhang Xiaoya. ”

"We learned from the forensic examination report that there were some debris in the cracks of Zhang Xiaoya's nails, and those debris were not anything else, but small pieces of flesh on your wound. ”

Wang Bing suddenly raised his head and stared at Gu Chen incredulously.

"You don't have to look at me like that. Gu Chen's attitude was still indifferent, and he said: "Those small pieces of meat that were grabbed from your wounds should be consistent with the wounds on the back of your hands, we can prove this through testing, what do you say? ”

"Police...... Comrade policeman. Seeing that Gu Chen had already found out that he was tired, no matter how much he quibbled, he was undoubtedly fighting against interrogation.

Wang Bing was a little scared, and his body began to tremble.

Gao Cheng took the camera and said to the back of Wang Bing's hand: "Wang Bing, stretch out your hand and show the wound." ”

Wang Bing didn't dare to disobey, so he had to do as he was told, pointing the wound on the back of his hand at the camera lens.

"Let me ask you, is this wound caused by Zhang Xiaoya?"

"No...... No. Wang Bing lowered his head and shook his head slightly.

Gao Cheng frowned and continued, "Be louder, is it?"

"Yes...... Yes!" Looking at Gu Chen and Gao Cheng's sharp eyes, Wang Bing was a little frightened, so he had to nod and admit.

"Wang Bing. At this moment, Gu Chen also struck while the iron was hot, and continued to ask him: "Let me ask you again, is the wound on the back of your hand caused by Zhang Xiaoya?"

"Yes, she caused it. ”

"Did you kill that Zhang Xiaoya?" Gu Chen asked again.

"Yes...... I killed it, and I killed Zhang Xiaoya. Wang Bing was powerless to resist the investigation.

In the black market, everyone has stolen goods, and the wounds on his body can match the crumbs analyzed by Zhang Xiaoya's nails.

Wang Bing knew that he could hide from the first year of junior high school, but not from the fifteenth.

What should come will come.

Elevation smiled, put the camera back at the right angle, and sat back in his seat.

Gan Wenfeng has also recorded a large section, and he has recovered a lot.

Gu Chen also took two steps back and continued to ask him, "Wang Bing, tell me what your profession is?"

Wang Bing looked up at Gu Chen, but soon he lowered his head again and said weakly, "I...... I don't have a permanent job, I've been a vagrant since three years ago. ”

"Then what do you live on?" Gu Chen asked.

"I ......" Wang Bing hesitated for a moment, and the whole person also regretted it: "I just relied on stealing chickens and dogs to barely survive, but later, I met some friends in the gold market, most of these people process gold for a living." ”

"When customers take the gold to them for jewelry, they will try their best to deduct some of it, earn processing fees, and save some private goods, and turn the accumulated gold into jewelry to continue to sell. ”

Gu Chen nodded and continued to ask him: "So you have been working in the gold market all these years, so you should have committed a lot of crimes, right?"

Before Wang Bing could answer, Gao Cheng said: "There are often victims whose gold necklaces are stolen and robbed before, it should all have something to do with you, right? ”

"I didn't ...... That's right. Wang Bing did not deny it, and said directly: "I have robbed other people's jewelry, and I am only interested in gold, because gold is valuable, so I have been relying on these things to barely make a living in the past few years." ”

"Who are you selling to??, these gold jewelry processing shops?" Gu Chen asked.

Wang He nodded: "Yes, sometimes it is also sold to places like the gold store in the high-tech zone, they are large enterprises, there are many chains, and they also have their own processing masters, so they will buy some gold in the market to process." ”

"But one thing is very important, a lot of the gold I sell to these places is not clean, and I have to go through those gold jewelry processing shops, melt the gold jewelry, and then make it and sell it quickly, so that I can wash away the possibility of the owner recovering the stolen goods. ”

Elevation is also a gritted tooth to hear......

I didn't expect this Wang Bing to know a lot of things in the gold market.

If Wang Bing does this, once the gold jewelry is melted into gold nuggets, it will be difficult for the police to trace the final clues based on the objects reported by the previous owner.

After all, the stolen goods have changed, which is why the police often do not match the items reported by the owner when tracking down some gold stolen goods.

In fact, many times, these seemingly completely different pieces of jewelry are actually made from the jewelry of the owner.

As soon as the nature changes, all clues will be interrupted.

Gu Chen nodded, and after learning about these circumstances, he asked Wang Bing again: "Then why did you kill Zhang Xiaoya, what is your relationship with Zhang Xiaoya?"

"I ...... Me and Zhang Xiaoya?" Wang Bing was suddenly silent, and after a while, he replied with a squeak: "Zhang Xiaoya and I were both tenants of an apartment before. ”

"You two used to be roommates?" Gao Cheng couldn't help but ask.

"Yes. Wang Bing did not deny it, and continued: "That is after I made a batch of stolen goods, I rented a better apartment. ”

"That apartment, Zhang Xiaoya and her colleagues originally lived together, but after her colleagues moved out, only the two of us remained. ”

"And this is a two-story duplex apartment, I rent the lower floor, she rents the upper floor, and later in the process of some exchanges, she found out that I was generous, so she asked me about how to make money, and I also promised to take her and let her be my apprentice. ”

"It was during that time that we began to date, and I gave her a lot of money, and she knew that my gold was not clean. ”

"Later, she said she wanted to leave me, she fell in love with a bus driver, and we had a big fight, and I threatened her, but she decided to go and moved out of the apartment and into the rental house where she lives now. ”

Looking at the sharp eyes of the three policemen, after a pause, Wang Bing said again: "I know that she will leave me after all, but I am unwilling, I have pestered her, and she has also asked me how I am willing to let her go." ”

"So I suddenly thought of the gold store in the high-tech zone, according to my many investigations, I found that their security system has obvious loopholes, and the gold jewelry over there is so much that people covet. ”

"I even thought about using a sack to hold gold, but I had to have a deputy, so I thought of Zhang Xiaoya. ”

When he said this, Wang Bing's eyes ...... It's clear that things are starting to change.

......
