"The 326 disappearance case... was a case three years ago." Wei Zhenguo's tone was slightly reminiscent, and he said slowly: "You know, there are certain requirements for filing a disappearance case. So, when the case was transferred to me , In fact, there are already many not-so-good signs that have appeared.”

Wei Zhenguo had obviously reviewed the case. He paused briefly and continued: "The victim Ding Lan was the accountant of the factory. On March 26, she worked overtime until around 10 p.m. and then left the factory to go home. The next day there was no She went to work on time, but her colleagues at the factory thought she was just late and waited until the afternoon before trying to contact her. Ding Lan lived alone, so her family did not report the case until the evening of the 27th, but the case was not immediately filed at that time. After that, they started searching Several of Ding Lan's people found Ding Lan's bicycle behind the municipal flower bed seven or eight meters away from the driveway."

"The case can be filed." Wu Jun interjected.

"Yes, the abandoned bicycle shows that there is another hidden reason for the disappearance." Wei Zhenguo sighed and said: "After that, our squadron did some search work and took fingerprints from the bicycle, but there was no progress. The case ended It came to a standstill.”

"Let me take a look at these fingerprints." Jiang Yuan has no other criminal investigation methods that he is good at. Fingerprints are his sharpest weapon at the moment, much sharper than the forensic skills themselves.

Wei Zhenguo came to him to look at this case, and it could only be because of this reason.

Opening the comprehensive police application platform, there is a long row of fingerprints related to 326 missing cases.

Among them, the most important ones are the fingerprints collected on the bicycle. There are dozens of fingerprints in total, belonging to multiple people and located all over the handlebars, body and tires.

It can be said that the person who collects fingerprints is quite serious about collecting fingerprints.

However, similar to the previous injury case, the fingerprints obtained from the cylindrical car body material were very deformed and difficult to match.

Coupled with the large number of fingerprints collected from the victim's home, the number of fingerprints involved in the entire case could easily be dozens higher.

Without a clear investigation direction, these dozens of fingerprint processing are enough for a person to drink a pot.

Wei Zhenguo was obviously aware of this and could only explain: "Ding Lan's bicycle is often lent to people in the office to ride. Especially the cashier and another financial staff often ride it. In addition, Ding Lan is making friends On the other hand, it is more casual. There are many relatives, friends, best friends, and boyfriends. We know of 4 ex-boyfriends who live in this county..."

"Emotional entanglement?" Wu Jun made a blind guess. There was no body in this case, and it was not a major case. Two years later, he had no impression of it at all.

Wei Zhenguo shook his head: "Several of her ex-boyfriends broke up peacefully, and they were not violent... To be honest, after we recorded the confession, the case stopped, and there were basically no follow-up resources. If it weren't for that bicycle It is indeed strange. This case may not reach me... But it is precisely because the abandoned bicycle is so strange that I will always remember this case..."

Wu Jun listened and suddenly sighed: "In China, the so-called perfect murder can actually be replaced by a missing case. The time for filing a case alone can consume 72 golden hours. Without a body, many evidences will be lost." It can’t be found. Moreover, there won’t be so much manpower and material resources invested in it.”

Wei Zhenguo nodded heavily and looked at Wu Jun: "You feel it too?"

Wu Jun said "Yeah..." and said: "It is impossible to throw the bicycle on the side of the road for no reason. However, there are other explanations. The most critical problem is... there is no body."

"Yes. Wei Zhenguo sighed again.

Jiang Yuan understood and said in surprise: "Captain Wei, do you think there is a murder case here?"

Wei Zhenguo said: "It's a pity that the feeling doesn't count."

Jiang Yuan was young after all, and frowned: "No matter what, the person is really missing, and he must be found."

Wei Zhenguo smiled bitterly: "There is a huge difference between a disappearance case and a murder case."

Wu Jun also said: "Disappearances include fake disappearances. For example, you eloped with your boyfriend, ran away or evaded debts due to financial problems, or actively participated in pyramid schemes and strange religions, and there are also, as you young people say, , come to a trip that just goes away, and come to a destined love..."

"Well, our police force is limited and our energy is limited. Without certain evidence, it is impossible to actively turn a disappearance case into a murder case." Wei Zhenguo said.

Wei Zhenguo and Wu Jun showed the situation to Jiang Yuan with just one sentence.

Jiang Yuan asked hesitantly: "What is the definite evidence?"

"Just the corpse." Wei Zhenguo said: "The domestic tradition is to file a case upon seeing the corpse. Without a corpse, it is impossible to throw hundreds of millions of dollars into a case."

The high-pressure that murder cases must be solved is the original driving force for the police department to solve cases regardless of cost. However, just because there is no cost involved in murder cases does not mean that the police department’s funds are unlimited.

On the contrary, it is precisely because of the need to save funds to reserve for serious cases such as murder cases that the funds for ordinary cases are even more stretched.

Before seeing the body, the disappearance case was just an ordinary case.

The resources it can obtain can only be those for ordinary cases.

"The victim's position is an accountant. Does he have any financial problems?" Wu Jun raised a new question.

Wei Zhenguo sighed: "The preliminary investigation shows that there are no major problems, but there are some minor problems such as additional reimbursement. In short, it is not too clean. But the factory is unwilling to investigate in detail, and we do not have the manpower to investigate."

"I like to socialize and have fun. I have many ex-boyfriends and I am not too cautious when it comes to money." Wu Jun shook his head: "It is really difficult to turn a murder case around. He might suddenly run out one day and joke with you with a smile. .”

"It's been three years and she hasn't jumped out." Wei Zhenguo's expression became much heavier.

"Then, what do you need me to do now?" Jiang Yuan saw that his pressure was low and stood up again.

Wei Zhenguo adjusted his mood and thought: "That's what I thought about it. When we investigated the case before, our focus was on acquaintances. We considered acquaintances committing crimes and also considered issues such as male-female entanglements. In short, It’s just based on interpersonal relationships. For now, let’s put aside the old ways and focus on this bicycle.”

When it came to the investigation of the case, Wei Zhenguo's thinking became extremely quick, and he frowned deeply and said: "The only flaw in this case is the bicycle. If it weren't for the bicycle that fell in the grass, the disappearance case would probably be difficult to solve." File a case. And it is actually very easy to cover up this bicycle. If you ride it away or discard it on the side of the road, it may be ridden by other passers-by, leaving no trace of it."

Jiang Yuan nodded. This kind of case analysis was still very new to him, a forensic doctor who graduated from the Medical College.

"So, this bicycle represents a certain sporadic nature of the case and the possibility of a crime of passion. If a crime occurs, there is a high probability that the bicycle will leave bigger flaws, such as the suspect's fingerprints. "Wei Zhenguo looked at Jiang Yuan and said, "To be honest, I had considered this aspect three years ago, but it was more difficult to match fingerprints back then than it is now..."

Following Wei Zhenguo's description, the translucent interface of the system jumped out in front of Jiang Yuan.

Mission: Match all over the world

Mission content: Wei Zhenguo believes that clues to the disappearance of Ding Lan in 326 may exist in the fingerprints on the bicycle. Please match the fingerprints collected on the bike and try to solve the case.

Jiang Yuan's eyes twitched.

Good guy, match all the fingerprints on the bicycle, throw away 70% to 80% of the previously matched fingerprints, and the rest are all difficult fingerprints - really only if there is a major criminal case, can people have the patience to search them all. do it.
