Wang Qian looked at Gu Chen blankly, then shook her head.
"You don't know?" Gu Chen said.
"Comrade police, 20 years." Wang Qian stretched out two fingers and said weakly: "If I say I remember these things from 20 years ago, I must be lying."
"But I can tell you that the man was tall and thin, and had a black mole under his ear. This impressed me deeply, because I also have a black mole under my ear."
After she finished speaking, Wang Qian measured the right side of her face, pointed under her right ear and said, "Did you see it? It's just that that person's mole is much bigger than mine. At first glance, it's very obvious."
Based on Wang Qian's story, Gu Chen recorded the specific characteristics of the tape purchaser and asked, "Are there any other characteristics?"
"Well, 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 and asked Wang Qian: "How can you conclude that it is a Jiangbei accent? Do you understand Jiangbei dialect?"
"Of course, my wife 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 them long ago."
It feels like Wang Qian's visit is not fruitless. At least it shows that the man who once came to the store to buy tape must be related to the murderer.
Considering the authenticity of Wang Qian's account, Gu Chen decided to return to Jiangnan City to find other shop owners who opened shops opposite the city's No. 3 Middle School to verify Wang Qian's story.
On the other hand, Gu Chen still needs to discuss the specific situation Wang Qian explained.
But Gu Chen found the same type of tape from 20 years ago in Wang Qian's stationery store.
But so far, Gu Chen has not found any connection between the woman named Wang Qian and the victim Lu Jun.
Returning to the Criminal Investigation Team of the Hangcheng Branch, everyone still sat together and discussed intensively.
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, the biggest fear 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 90% chance that it was left by the criminal suspect. But sometimes it just happens that the fingerprint does not belong to the criminal suspect."
"Wang Qian is that 10%?" Yuan Shasha asked.
Gu Chen nodded silently: "Probability is hard to say."
"But this clue is crucial. In order to approve this clue, our criminal investigation colleagues in Hangzhou need to conduct in-depth investigations around this Wang Qian's life experience, social relationships, economic transactions, activity trajectories, etc."
"Don't worry, leave it to us." said the first-level superintendent of the criminal investigation team: "After several studies and judgments, we can actually rule out the possibility of her committing the crime, because this fingerprint is most likely from before she sold the tape.
It’s glued on.”
"This is 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, and at least we have a deeper impression of the murderer."
When Gu Chen said this, he was actually trying to comfort everyone.
After all, the fingerprints on which they had so much hope suddenly lost their value and meaning. Everyone involved in the investigation felt as if they had lost a treasure that had been treasured for a long time, and felt empty in their hearts.
…
…
Not long after returning from Hangzhou, Gu Chen went directly to the Technical Section of the Municipal Bureau and sent Officer Ding and Wu Xiaofeng to investigate Wang Qian's store conditions back then. The main purpose was to ask the proprietresses of several stores opposite the No. 3 Middle School in the city if they were
I discussed the issue of the floating corpse case with Wang Qian.
It was also to verify Wang Qian’s confession.
Although Gu Chen has no hope for Wang Qian's clue, necessary supplementary investigation is still needed.
It was also on the way back to Jiangnan City that Gu Chen received a call from Gao Chuanfeng, saying that he had made some progress in palm prints.
Therefore, as soon as Gu Chen and his team members returned to Jiangnan City, they did not return to Furong Branch, but went directly to the Technical Section of the Municipal Bureau.
When they arrived at the examination room, Forensic Doctor Liu and Gao Chuanfeng had been waiting there for a long time. The first time they saw Gu Chen, Forensic Doctor Liu grabbed Gu Chen and walked in: "Gu Chen, come with me."
"Did you find anything?" Gu Chen asked.
Forensic doctor Liu threw one of the documents to Gu Chen and said, "We have been studying fingerprints before, but I heard you called from Hangcheng and said that the fingerprints may have been left on it before purchasing."
"So based on your idea, I immediately focused all my attention on these two small pieces of palm prints. This time, an old expert happened to be studying in Jiangnan City, and he has done a lot of research on finger and palm print comparisons.
So I asked him about it."
"So there is a breakthrough?" Gu Chen asked.
Forensic Doctor Liu smiled lightly: "What do you think?"
"I can tell just by looking at your expression, why do you need to guess?" Gu Chen saw hope in Forensic Doctor Liu's expression.
Forensic Doctor Liu also nodded fiercely: "Yes, there was a breakthrough. Fortunately, 20 years ago, in order to peel off these two small pieces of palm prints from the adhesive tape, the men from the criminal investigation team and I really did it
It took a lot of effort."
Pointing to the picture information on the document, Forensic Doctor Liu added: "The extraction quality of these two small palmprints is very high and very clear. This is the evaluation given by the old expert."
"Forensic Doctor Liu." Gu Chen nodded silently after hearing this: "I know that nationwide, the construction of the palmprint database is still in its early stages, and we in Jiangnan City do not have many palmprint database samples."
"But it is quite difficult to compare, not to mention the samples from 20 years ago."
"You don't have to worry about this now." Forensic Doctor Liu glanced at Gao Chuanfeng beside him, beckoned and said, "Gao Chuanfeng, why are you still standing there? Hurry and get the information."
"Oh." After hearing this, Gao Chuanfeng, who was in a daze, quickly ran to a few people, handed over the information in his hand and said:
This chapter is not over yet, please click on the next page to continue reading! "This is the information we matched in the past two days after entering these two small pieces of palm prints based on the advice of the old expert, and it quickly jumped out
There are several pieces of information that are very similar."
"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 it?" Gu Chen smiled faintly when he heard this, and asked hurriedly: "Then why was there no matching success before? Is it because the palm print database information is limited?"
"Yes." Forensic Doctor Liu smiled lightly and explained: "Many of the previous information databases were not fully integrated into the Internet. This time, with the help of experienced experts, we obtained a lot of new palm print information."
"After this comparison, I made a lot of choices, and finally found a matching one through the manual visual recognition comparison by the old expert."
Gao Chuanfeng said with a smile: "Using artificial naked eye recognition and comparison is really a headache for us ordinary people, but the old expert is more amazing. He happens to specialize in this topic, so he quickly found a matching one.
."
Gu Chen looked through the information in his hand and asked, "So this man named Zhang Quan is the one whose palm prints on the tape match, right?"
"Yes." Gao Chuanfeng outlined two small pieces of incomplete palm prints with a pen: "Did you see? Although the palm prints are incomplete, they can be made up for and based on the direction of the palm prints. These broken parts can still be repaired.
Connecting the parts together is the brilliance of the old expert."
"We previously thought that the palm prints extracted were not ideal, but in the hands of others, the palm prints can be played to perfection."
"And now many places have begun to establish palm print databases, so finding this person named Zhang Quan this time is a case of a blind cat meeting a dead mouse."
"Same as you last time?" Gu Chen was also overjoyed when he heard this.
With this clue, the efficiency of searching will be greatly increased.
Lu Weiwei took the information from Gu Chen and flipped through it and found that this man lived in Jiangnan City at this time.
But when he looked again, he frowned: "Is this person still a big boss of the company?"
"That's right." Forensic Doctor Liu nodded slightly and explained: "This man named Zhang Quan has a big business now and his family is well off."
"But according to our repeated checks, his palm print information is almost completely consistent with the two small pieces of palm print information we extracted from the tape before."
"Just call him and ask him." Gu Chen lowered his head and looked at his watch. It was already 4 o'clock in the afternoon.
Lu Weiwei asked: "Now?"
Gu Chen thought for a moment and then changed his words: "It's better to wait first. Don't alert the enemy. Investigate Zhang Quan first and then make a conclusion."
"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, preparing for He Junchao to investigate this person's situation.
After completing all operations, Gu Chen shook hands with Forensic Doctor Liu and said, "Forensic Doctor Liu, thank you this time."
"Where are you talking?" Forensic Doctor Liu frowned and said with emotion: "This case spans 20 years."
"It would be great if there was such complete information back then, but it's a pity that it has been allowed to slip through the net for 20 years."
"If the murderer is really this person named Zhang Quan, it can only mean that it is a shame for our investigators."
"Don't worry, Forensic Doctor Liu, leave the matter to us." Gu Chen understood Forensic Doctor Liu's mood at this moment very well.
If the murderer is really Zhang Quan, then Zhang Quan, now an entrepreneur, is indeed a mockery of the police officers who worked so hard to investigate.
Not waiting for time, Gu Chen quickly returned to Furong Branch with the information and forensic doctor Liu's explanation.
At this moment, He Junchao was also intensively investigating Zhang Quan's information.
Seeing that Gu Chen and 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 had a look on his face: "Have you ever seen me, He Junchao, slow down? Maybe this job is a challenge for others, but for me, He Junchao, it's easy."
"Look how loud you are, you're almost going to heaven, aren't you?" Lu Weiwei walked up to her angrily and looked down.
He Junchao immediately scrolled the page and introduced it casually.
"This Zhang Quan, even though he has a big factory now, he had a history of fraud back then."
"Fraud experience?" After hearing He Junchao's words, Gu Chen hurriedly asked: "What kind of fraud are you referring to?"
"Well, of course it's my experience of swindling cars and pawning them off many times. I've sorted them out."
After he finished speaking, He Junchao immediately clicked on other compiled information and said: "I conducted an investigation on Zhang Quan's personal experience and found that Zhang Quan was also a gangster in his early years. I found that he had many experiences of cheating and pawning cars."
Clicking on the next page, He Junchao said again: "Did you see it? These are the transcripts of my colleagues from the past that I retrieved from the database. I really want to thank those colleagues who did a solid job in the basic work. The transcripts from that year are very detailed.
, only then can we find a breakthrough."
Gu Chen looked through the files hard and raised the corners of his mouth slightly: "This guy was a master of fraud 20 years ago?"
"Isn't that right? Even though he is a prosperous person now, he can't wipe away all the fraud cases he committed back then." He Junchao clicked on the next page of information and said:
"Did you see that, according to the case records of my colleagues at that time, the person who took the inquiry transcript was the boss of a commercial bank. He said that a man drove his car to the commercial bank to pawn it, and submitted the vehicle driving license, the owner's ID card, and the purchase price of the vehicle.
The surcharge payment voucher, etc., that was his first time."
"I originally made an appointment to pick it up a month later, but the car was picked up a week later. I came back to pawn the car again a week later, and it hasn't been picked up since."
"Later, the business owner discovered that the car was a fake and all the procedures were fake."
This chapter is not over yet, please click on the next page to continue reading! "So the owner of the trading company chose to call the police. According to the police's inquiry of the owner of the trading company at the time, they found that the man who was working as a driver was in his 30s, about 1.7 meters tall, with a medium build.
He speaks with a Jiangbei accent and looks the same as on the fake ID card."
"Later, the police conducted a very careful investigation of the Santana car, but since it had been a year and a half since the incident and many people had come into contact with the car, they did not find any information related to the case."
After a pause, He Junchao added: "These are just records from more than 20 years ago, that is, some of the things that happened before Lu Jun was murdered."
"At that time, Zhang Quan basically relied on this kind of fraud to make a living."
"Then the fingerprints were not recorded back then?" Lu Weiwei asked.
He Junchao explained with a smile: "The top priority at that time was still fingerprints. However, with the development of fingerprint technology and the construction of fingerprint databases in various places, our Jiangnan City Police has never stopped fingerprint comparison work, but there has been no successful comparison.
."
"What's more, after Lu Jun was murdered, the fingerprints forensic doctor Liu found on the tape had nothing to do with Zhang Quan."
"Let's not talk about this 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.
"Did you see that? The counterfeiting technology back then was quite powerful, but the devil is always better than the devil. Over the years, as long as we hear about a taxi robbery happening somewhere, our Jiangnan City police will follow the example of Lu Jun's murder.
Let’s put all the cases together for comparison and judgment.”
"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 that of the person and the photo is not clear, we can still use new technology to conduct multiple searches and comparisons.
right."
"But 20 years ago, it was really difficult. It was enough for my colleagues at that time to identify Zhang Quan's fake documents."
"In just these few years, Zhang Quan's bad luck has turned him into an entrepreneur. Now he is very prosperous and often does charity, which can be regarded as a way to clear his name."
After a pause, He Junchao added: "But to outsiders, maybe he has been cleared, but for us, the case record can still clearly show what he has done?"
"Which car dealer did the report come from?" Gu Chen asked hurriedly after hearing what He Junchao said.
He Junchao lowered his head and looked, then searched again, and then said: "It's called Volkswagen Home. It's an early place that sells used cars in Jiangnan City."
"Is this car dealership still there now?" Gu Chen asked again.
He Junchao clicked on the computer keyboard for a while before replying: "Hey, dear, this car dealership now has 10 branches in Jiangnan City?"
"Where is the store where the crime was reported?" Lu Weiwei asked.
He Junchao pointed to the address in the lower corner of the screen and said: "No. 125, Xin'an Road."
"Let's go." Gu Chen didn't have time to think too much. Not long after he walked in, he was about to start again.
He Junchao said hurriedly: "Don't you want to drink water before leaving? And Lu Weiwei, can you give me some of your bag of potato chips? I'm a little hungry."
"Here's a reward for you." Lu Weiwei was a rare generous person.
Without saying a word, He Junchao hurried to Lu Weiwei's drawer and put the shrimp-flavored potato chips in his bag.
…
…
On the other side, Gu Chen drove everyone to No. 125, Xin'an Road.
At this moment, this place is no longer the used car dealership it once was, but a restaurant.
Gu Chen walked to the cashier and asked, "Excuse me, there used to be a car dealership here called Volkswagen Home. Do you know where it moved?"
"Volkswagen Home?" Hearing this, the cashier boy pointed directly to the diagonal opposite side of the street not far away: "There is one over there, but I heard that Volkswagen Home car dealerships have opened many stores in Jiangnan City. You guys
If you want to buy or sell a car, just find any company."
"Thank you." Through the cashier's introduction, Gu Chen had already seen the Volkswagen dealership's sign from a distance.
At this moment, this car dealership called "Volkswagen Home" has become a luxury car exhibition area covering several hundred square meters.
Located downstairs in a new real estate business district.
Not only that, there are also various vehicles placed at the entrance. The scale looks stylish and relatively formal.
Seeing Gu Chen and everyone looking around, a uniformed front desk lady took the initiative to come out and greet her: "Welcome to Volkswagen Home Automobile Dealership. Are you buying or selling a car? We can help you with everything here."
"Can police cars also handle it?" Officer Wang asked.
The female receptionist smiled and nodded: "As long as it's a car business, we can handle it here, even pawn it, so please don't doubt it, because our car dealership is a time-honored one, and we are honest."
"I'm looking for your boss." Before the female receptionist could finish speaking, Officer Wang interrupted directly.
