I am a super cop

Chapter 1131

Wang Qian stared blankly at Gu Chen, then shook her head.

"You don't know?" Gu Chen said.

"Comrade policeman, 20 years." Wang Qian stretched out two fingers and said weakly, "If I say I remember something from 20 years ago, then I must be lying."

"However, I can tell you that the man is tall and thin, and has a mole under his ear. I am very impressed with this, because I also have a mole under my ear."

After finishing speaking, Wang Qian measured her right cheek, pointed to the right ear and said, "Did you see it? It's just that the mole on that person is much bigger than mine. It's very obvious at first glance."

Based on Wang Qian's narration, Gu Chen recorded the specific characteristics of the person who bought the tape, and asked, "Are there any other characteristics?"

"Uh, I don't speak Mandarin very well, and I don't have a local accent in Jiangnan City. Maybe I have a Jiangbei accent."

"Jiangbei accent?" Gu Chen hesitated for a moment, then asked Wang Qian, "How did you conclude that it was Jiangbei accent? Can you understand Jiangbei dialect?"

"Of course, my lover is from Jiangbei, and he speaks with a Jiangbei accent, so I know this very well."

"It is precisely because of these characteristics that I can remember some characteristics of this person, otherwise I would have forgotten it long ago."

I feel that Wang Qian's place is not fruitless, at least it shows that the man who once came to the store to buy tape must have something to do with the murderer.

Considering the authenticity of Wang Qian's account, Gu Chen decided to go back to Jiangnan City and find other shop owners who opened a shop opposite Shi No. [-] Middle School in order to verify Wang Qian's statement.

On the other hand, Gu Chen still needs to discuss the specific situation that Wang Qian explained.

But Gu Chen found the same type of adhesive tape 20 years ago in Wang Qian's stationery store.

But so far, Gu Chen has not found any connection between this woman named Wang Qian and the victim Lu Jun.

Returning to the criminal investigation team of the Hangzhou branch, everyone still sat together and discussed together.

Nie Qin said: "Our investigators investigated very carefully, but the more they investigated, the more they felt that this woman did not seem to be involved in the case."

"When handling a case, what I'm most afraid of is going in the wrong direction." Gu Chen crossed his arms and said thoughtfully:

"Judging from the location where the fingerprint was extracted, there is a [-]% possibility that it was left by the criminal suspect, but sometimes it is such a coincidence that this fingerprint is not the suspect's."

"Wang Qian is that [-]%?" Yuan Shasha asked.

Gu Chen silently nodded: "Probability is hard to say."

"But this clue is very important. In order to approve this clue, the criminal investigation colleagues in Hangzhou need to conduct in-depth investigations around Wang Qian's life experience, social relations, economic contacts, and activity trajectory."

"Don't worry, leave it to us." The first-level superintendent of the criminal investigation team said: "After several researches and judgments, we can finally rule out the possibility of her committing the crime, because this fingerprint is likely to be her fingerprint before she sold the tape. Glued on."

"It's also possible." Nie Qin glanced at Gu Chen and asked, "What do you think? Captain Gu."

"Maybe, but at least we got some important clues from Wang Qian's place. At least we have a deeper impression of the murderer."

When Gu Chen said this, he was actually comforting everyone.

After all, the fingerprints with high hopes suddenly lost their value and significance. Everyone who participated in the investigation seemed to have lost a treasure that had been cherished for a long time, and their hearts were empty.

……

……

Not long after returning from Hangzhou, Gu Chen went directly to the technical department of the Municipal Bureau, and sent police officer Ding and Wu Xiaofeng to investigate Wang Qian's store conditions, mainly to ask the proprietresses of the shops opposite the No. [-] Middle School in the city. Discussed the floating corpse case with Wang Qian.

It was also to prove Wang Qian's confession.

Although Gu Chen has no hope for Wang Qian's clue, necessary supplementary investigations are still needed.

Also on the way back to Jiangnan City, Gu Chen received a call from Gao Chuanfeng, saying that he had made some progress in palm prints.

Therefore, when Gu Chen and the team members returned to Jiangnan City, they did not return to the Furong Branch, but went directly to the Technical Section of the Municipal Bureau.

When they came to the testing room, Fayi Liu and Gao Chuanfeng had been waiting there for a long time. The first time they saw Gu Chen, Fayi Liu grabbed Gu Chen and walked in: "Gu Chen, come with me."

"Did you find anything?" Gu Chen asked.

Forensic Liu threw one of the documents to Gu Chen and said, "We have been researching fingerprints before, but I heard from you that you called from Hangcheng and said that the fingerprints may have been left on them before the purchase."

"So according to your idea, I immediately focused all my attention on these two small palmprints. This time, there happened to be an old expert who was studying in Jiangnan City, and he had a lot of research in finger-palmprint comparison. So I asked him about it."

"So there is a breakthrough?" Gu Chen asked.

Forensic Liu smiled faintly: "You guess?"

"You can tell just by looking at your expression, so you don't need to guess?" Gu Chen saw hope in Liu Fayi's expression.

Forensic Liu also nodded fiercely: "Yes, there is a breakthrough. Fortunately, 20 years ago, in order to peel off these two small pieces of palm prints from the adhesive tape that was stuck together, the men in the criminal investigation team and I really worked together. It took a lot of effort."

Pointing to the picture information on the file, Forensic Liu said again: "The quality of the extraction of these two small pieces of palmprint is very high, and it is also very clear. This is the evaluation given by the old expert."

"Forensic Liu." Gu Chen also nodded silently when he heard the words: "I know, as far as the whole country is concerned, the construction of the palmprint database is still in the early stage, and the samples of the palmprint database in our Jiangnan City are not too many."

"But it is quite difficult to compare, not to mention the samples from 20 years ago."

"You don't have to worry about that now." Forensic Liu glanced at Gao Chuanfeng beside him, beckoned and said, "Gao Chuanfeng, what are you still doing there? Hurry up and get the information."

"Oh." Gao Chuanfeng, who was a little dazed, heard the words, and then ran to the few people in small steps, handed over the information in his hand and said:
"This is the information matching we performed after entering the two small pieces of palmprint according to the old expert's suggestion in the past two days, and a few pieces of information with high similarity quickly popped up."

"Later, after the old expert's manual visual recognition and comparison, he locked on one of the men, and his matching degree was very high."

"So that's the case?" Gu Chen smiled lightly when he heard the words, and quickly asked, "Why didn't the matching succeed before? Is it because the palmprint database has limited information?"

"Yes." Forensic Liu smiled lightly and explained, "Many of the previous information databases have not been fully integrated into the Internet. This time, with the help of old experts, I have obtained a lot of new palmprint information."

"After this comparison, there were thousands of choices, and finally found the matching one in the old expert's artificial naked eye recognition comparison."

Gao Chuanfeng smiled and said: "Using artificial naked eyes to identify and compare, we ordinary people are really a bit of a headache, but that old expert is quite amazing, he happens to specialize in this topic, so he quickly found a matching one. .”

Gu Chen looked at the information in his hand and asked, "So this man named Zhang Quan is the one who matches the palm print on the tape, right?"

"Yes." Gao Chuanfeng outlined two small pieces of incomplete palm prints with a pen: "Did you see that? Although the direction of the palm prints is incomplete, it can be made up for, and then according to the direction of the palm prints, these gaps can still be broken Partially connected, this is the brilliance of that old expert."

"Before we thought that the extracted palm prints were actually not ideal, but in the hands of others, the palm prints can be played to perfection."

"And now many places have begun to establish palmprint databases, so if we can find this person named Zhang Quan this time, it is a blind cat meeting a dead mouse."

"Same as you last time?" Gu Chen was overjoyed when he heard this.

With this clue, the efficiency of searching will be greatly increased.

Lu Weiwei took the information from Gu Chen, flipped through it and found that this man was living in Jiangnan City at this time.

But looking at it again, he frowned immediately: "Is this person still a big boss of the company?"

"That's right." Forensic Liu nodded slightly and explained, "This man named Zhang Quan has a big business and a wealthy family."

"But according to our repeated checks, his palmprint information is almost completely consistent with the two small pieces of palmprint information we extracted from the tape before."

"Just call him and ask." Gu Chen looked down at his watch, it was already 4 o'clock in the afternoon.

Lu Weiwei asked, "Now?"

Gu Chen thought for a moment, then changed his mind and said: "Let's wait first, don't startle the snake, investigate Zhang Quan first, and then draw conclusions."

"I think this is feasible." Officer Wang agreed very much, so he took out his mobile phone and took pictures of all the document information on the file.

Then it was sent to He Junchao, ready to ask He Junchao to investigate this person's situation.

After completing all operations, Gu Chen shook hands with Forensic Liu and said, "Forensic Liu, thanks to you this time."

"Where are you talking?" Forensic Doctor Liu frowned, feeling quite emotional, "This case spanned 20 years."

"It would be great if there was such perfect information back then, but it's a pity that the fish that slipped through the net have been free for 20 years."

"If the murderer is really this man named Zhang Quan, it can only show that it is a disgrace to our investigators."

"Don't worry Liu Fayi, leave the matter to us." Gu Chen understood Liu Fayi's mood very well.

If the murderer is really this Zhang Quan, then Zhang Quan, who is now an entrepreneur, is indeed a mockery of the police officers who worked hard to investigate back then.

Not waiting for time, Gu Chen hurried back to the Furong branch with the materials and the explanation of Forensic Doctor Liu.

At this moment, He Junchao is also intensively investigating Zhang Quan's information.

Seeing that Gu Chen and the others had arrived, He Junchao also snapped his fingers and said, "I've already sorted out the things you want."

"So fast?" Lu Weiwei was quite surprised.

He Junchao looked embarrassed: "When have you seen me, He Junchao, slow down? Maybe this job is a challenge for others, but for me, He Junchao, it's so easy."

"Look at you, you're about to go to heaven, right?" Lu Weiwei walked to her side angrily, and looked down.

He Junchao immediately scrolled the page and introduced it casually.

"This Zhang Quan, even though he owns a big factory now, he had a history of fraud back then."

"Experience in fraud?" Hearing He Junchao's remarks, Gu Chen hurriedly asked, "What kind of fraud are you referring to?"

"Uh, of course, it's the experience of cheating cars for cars many times. I have sorted them out."

After finishing speaking, He Junchao immediately clicked on other compiled materials and said: "I conducted investigations around Zhang Quan's personal experience and found that Zhang Quan was also a gangster in his early years, and found that he had many experiences of cheating on cars."

Clicking on the next page, He Junchao said again: "Did you see it? This is the record of my colleagues from the database. I really want to thank those colleagues who have done a solid job in the basic work. The records of the year are very detailed. , so that we can find a breakthrough.”

Gu Chen tried his best to flip through the file, and the corners of his mouth slightly raised: "This guy, was he a con artist 20 years ago?"

"Isn't it? Don't look at him as a person who is in a good position now, but he can't erase the fraudulent cases back then." He Junchao clicked on the next page of the information, and said:

"Did you see it? According to the case records of my colleagues back then, it was the owner of a commercial firm who made the interrogation record. He said that a man drove the car to the commercial firm for pawning, and submitted the vehicle driving license, the owner's ID card, and the purchase of the vehicle. Surcharge payment certificate, etc., that was the first time for him to do so.”

"I made an appointment to pick it up for a month, but the car was picked up a week later, and I came back to pawn the car again a week later, and I haven't picked it up since then."

"Later, the owner of the firm found out that the car was a license plate, and all the procedures were fake."

"So the owner of the commercial firm chose to call the police. According to the police's inquiries with the owner of the commercial firm at the time, it was found that the man in the car was in his 30s, about 1.7 meters tall, of medium build, with a Jiangbei accent, and his appearance was the same as that on the fake ID card."

"Later, the police conducted a very careful investigation of the Santana car, but because it has been a year and a half since the incident and many people have come into contact with the car, no information related to the case was found."

After a pause, He Junchao said again: "These are just records from more than 20 years ago, that is, what happened before Lu Jun was murdered."

"At that time, Zhang Quan basically lived on this kind of fraud."

"Didn't the fingerprints be recorded back then?" Lu Weiwei asked.

He Junchao explained with a light smile: "Fingerprints were still the most important thing at that time, but with the development of fingerprint technology and the construction of fingerprint databases in various places, our Jiangnan City police have not stopped fingerprint comparison work, but there has been no comparison. .”

"What's more, after Lu Jun was murdered, the fingerprints found on the tape by Forensic Doctor Liu have nothing to do with Zhang Quan."

"Let's not talk about that first, let's talk about Zhang Quan's fraud." Gu Chen said.

"Okay." He Junchao didn't seem to change the topic, and directly turned to the next page of information.

"See? The counterfeiting technology back then was quite powerful, but the magic is as high as one foot and one foot high. Over the years, as long as we heard that there was a taxi robbery, our Jiangnan police would be like Lu Jun who was killed. Let’s compare and judge the cases together.”

"And in recent years, our various technologies have developed rapidly. Although considering that the photo on the fake ID card provided by the criminal suspect may not be the person himself, and the photo is not clear, we can still use the new technology to search and compare multiple times. right."

"But 20 years ago, it was really difficult. It was enough for colleagues at that time to identify Zhang Quan's fake documents."

"In the past few years, Zhang Quan's dog shit luck has turned him into an entrepreneur. Now he is very prosperous and often does charity. It is a cleansing for himself."

After a pause, He Junchao said again: "For outsiders, maybe he has been cleansed, but for us, we can still see clearly what he has done in the case?"

"Which car dealership reported the crime?" Gu Chen hurriedly asked after hearing He Junchao's remarks.

He Junchao looked down, then searched again, and then said: "It's called Dazhongjia, and it's an early place to sell used cars in Jiangnan City."

"Then is this car dealership still there?" Gu Chen asked again.

He Junchao fiddled with the computer keyboard for a while before replying: "Hey, this car dealership is now in our Jiangnan City, and it has 10 branches?"

"Then where is the location of the store that reported the crime?" Lu Weiwei asked.

He Junchao pointed to the address in the lower corner of the screen and said, "Xin'an Road, No. 125."

"Let's go." Gu Chen didn't have time to think about it, he just entered the door not long ago, and now he has to continue to leave.

He Junchao hurriedly said: "Don't you just drink your saliva before leaving? And Lu Weiwei, can you give me some of your bag of potato chips? I'm a little hungry."

"This is your reward." Lu Weiwei was so generous once in a while.

Without further ado, He Junchao hurried to Lu Weiwei's drawer and pocketed the shrimp-flavored potato chips.

……

……

On the other side, Gu Chen drove everyone to Xin'an Road, No. 125.

At this moment, this place is no longer the second-hand car dealership of the past, but a restaurant.

Gu Chen walked to the cashier and asked, "Excuse me, there was a car dealer here called Dazhongjia, do you know where it moved?"

"Dazhongjia?" The cashier brother heard the words and pointed directly across the street not far away: "There is one over there, but I heard that the car dealership of Dazhongjia has opened many in Jiangnan City. If you want to buy or sell a car, just find one.”

"Thank you." Through the introduction of the cashier brother, Gu Chen has already seen the signboard of Volkswagen Automobile from a distance.

At this moment, the storefront of this car dealership called "Dazhongjia" is already a famous car exhibition area of ​​several hundred square meters.

Located downstairs in a new real estate commercial district.

Not only that, but there are also various vehicles at the door, and the scale looks decent and more formal.

Seeing Gu Chen and everyone looking around, a front desk lady in uniform stepped out to greet her, "Welcome to Dazhongjia Automobile Store. Are you buying a car or selling a car? We can help you here."

"Can police cars handle it too?" Officer Wang asked.

The female receptionist smiled and nodded: "As long as it is a car business, we can handle it here, and even pawn it, so please don't doubt it, because our car dealership is a time-honored brand, and there is no deception."

"I'm looking for your boss." Before the female receptionist could finish speaking, Police Officer Wang interrupted directly.
