"The missing case of 326... happened three years ago." Wei Zhenguo's tone was somewhat nostalgic as he slowly said, "You know, there are certain requirements for filing a missing case. So when the case was transferred to me, there were already many bad signs."

Wei Zhenguo had clearly reviewed the case. After a slight pause, he continued, "The victim Ding Lan was the accountant of a factory. On March 26th, she worked overtime until around 10 pm and left the factory to go home. She didn't show up for work the next day, but her colleagues thought she was just late. It wasn't until the afternoon that they tried to contact her. Ding Lan lived alone, so it wasn't until the evening of the 27th that her family reported her missing. The case wasn't filed immediately. Later, several people spontaneously searched for Ding Lan and found her bicycle behind a municipal flower bed about seven or eight meters away from the roadway."

"That's enough to file a case," Wu Jun interjected.

"Yes, the abandoned bicycle indicates that there is another hidden motive behind the disappearance," Wei Zhenguo sighed and said, "After that, our team did some searching work and also collected fingerprints from the bicycle. But we never made any progress and the case came to a standstill."

"I'll take a look at these fingerprints." Jiang Yuan didn't have any other detective skills he was good at. Fingerprints were his sharpest weapon, even sharper than his forensic skills.

The only reason Wei Zhenguo came to him to look at this case was probably for this reason.

Opening the police comprehensive application platform, there was a long list of fingerprints related to the missing case of 326.

Among them, the most important were the fingerprints collected from the bicycle, totaling dozens of fingerprints belonging to multiple people and distributed throughout the handlebars, body, and tires of the bicycle.

It can be said that the person who collected the fingerprints was quite serious.

However, similar to the previous assault case, the cylindrical material of the bicycle body caused severe deformation of the fingerprints, making it difficult to match.

In addition, a large number of fingerprints were collected from the victim's home, and the total number of fingerprints involved in the entire case easily exceeded dozens.

Without a clear direction of investigation, dealing with these dozens of fingerprints was enough to give a headache.

Wei Zhenguo was obviously aware of this and could only explain, "Ding Lan's bicycle was often borrowed by people in the office. Especially the cashier and another financial staff member, who often rode it. In addition, Ding Lan was quite casual in her social life, having many relatives, friends, best friends, and boyfriends who lived in the county. We know of at least four ex-boyfriends..."

"Emotional entanglements?" Wu Jun guessed blindly. This case had no body and was not a major case. It had been two years since it happened, and he had no impression of it.

Wei Zhenguo shook his head, "All of her ex-boyfriends had a peaceful breakup and no violent tendencies... To be honest, after recording their statements, the case came to a halt, and there were basically no follow-up resources. If it weren't for the fact that the bicycle was really suspicious, this case might not have come to me... But it was precisely because of the strange bicycle that I have always remembered this case..."

Listening to this, Wu Jun suddenly sighed, "In China, using a missing case to replace a perfect murder is actually enough. Just the time it takes to file a case can consume the golden 72 hours, and without a body, many pieces of evidence cannot be found. And there won't be so much manpower and resources invested."

Wei Zhenguo nodded heavily and looked at Wu Jun, "You also feel it?"

Wu Jun made a sound of "Hmm..." and said, "It's not possible to just throw a bicycle by the roadside for no reason. But there could be other explanations. The most crucial problem is... there's no body.""Yes." Wei Zhenguo sighed.

Jiang Yuan understood and asked in surprise, "Captain Wei, do you think there's a murder case involved?"

Wei Zhenguo replied, "Unfortunately, I don't think it's significant."

Jiang Yuan, being young, frowned and said, "Regardless, someone is missing, and we have to find them."

Wei Zhenguo smiled bitterly, "There's a big difference between a missing person and a murder case."

Wu Jun added, "There are also issues with false missing cases, such as elopement with a boyfriend, escaping or running away due to financial problems, participating in pyramid schemes or strange religions, and even going on a spontaneous trip or finding destined love, as young people like to say..."

"Well, our police force and energy are limited, and without conclusive evidence, it's impossible to turn a missing case into a murder case." Wei Zhenguo said.

Wei Zhenguo and Wu Jun explained the situation to Jiang Yuan.

Jiang Yuan hesitated and asked, "What do you mean by conclusive evidence?"

"A body." Wei Zhenguo said, "In China, we only file a case when a body is found. Without a body, it's impossible to spend millions of dollars on a case."

The pressure to solve a murder case is the primary motivation for the police to spare no expense. However, just because the cost is not a concern for murder cases does not mean that the police budget is unlimited. On the contrary, to save money for serious cases such as murder, the budget for ordinary cases is even more limited.

Until a body is found, a missing case is just an ordinary case, and it can only receive resources for ordinary cases.

"The victim was an accountant. Did she have financial problems?" Wu Jun raised a new question.

Wei Zhenguo sighed, "The initial investigation didn't reveal any significant issues, but there were some minor problems with additional reimbursements. In any case, the factory didn't want to investigate further, and we didn't have enough manpower to investigate."

"She liked to socialize, play around, had multiple ex-boyfriends, and wasn't too careful with money." Wu Jun shook his head, "It's challenging to turn this into a murder case. Who knows, maybe one day she'll come back and say it was just a joke."

"It's been three years, and she hasn't shown up." Wei Zhenguo's expression became much heavier.

"What do you need me to do now?" Jiang Yuan stood up, feeling the low pressure.

Wei Zhenguo adjusted his emotions and said, "This is what I'm thinking. When we investigated the case before, we focused on acquaintances, considering the possibility of crimes committed by acquaintances and issues related to romantic relationships. In other words, we investigated based on personal relationships. Now, we can put that aside and focus on this bicycle."

In terms of case investigation, Wei Zhenguo's thinking became extremely agile, and his brow furrowed deeply as he said, "The only flaw in this case is the bicycle. If it weren't for this bicycle lying in the grass, the missing case would be challenging to file. It's also easy to cover up this bicycle by riding it away or throwing it on the roadside, where it might be taken by another passerby and become even more difficult to track down."

Jiang Yuan nodded. This kind of case analysis was fresh for him as a forensic graduate.

"So, this bicycle represents the possibility of a crime of passion. If a crime were committed, the bicycle would be the most likely place to leave a significant flaw, such as the suspect's fingerprints." Wei Zhenguo looked at Jiang Yuan and said, "To be honest, I considered this three years ago, but matching fingerprints was even more challenging than it is now..."With Wei Zhenguo's description, a semi-transparent interface from the system appeared in front of Jiang Yuan.

Mission: Full Area Matching

Mission Content: Wei Zhenguo believes that there may be clues to the missing case of Ding Lan, case number 326, on the fingerprints collected from the bicycle. Please match the fingerprints collected from the bicycle and try to solve the case.

Jiang Yuan's eye twitched.

Wow, matching all the fingerprints on the bicycle, discarding the 70-80% of fingerprints previously matched, the remaining ones were all difficult fingerprints - it really takes a major criminal case to make people patient enough to match them all.
