Chapter 44: Ex-Boyfriends

For two consecutive days, Jiang Yuan concentrated his energy on processing the fingerprints of the Ding Lan case.

Because he solved several cases in a row, including homicide cases that attracted the attention of the whole bureau, Jiang Yuan's newcomer attribute was almost washed away cleanly, or rather, it was shining brightly.

Now, at least in the Ningtai County Bureau, everyone has heard the name "Jiang Yuan".

The most direct impact of this is that no one asks Jiang Yuan to do odd jobs.

Even Wu Jun, seeing Jiang Yuan busy doing fingerprints for the Ding Lan missing person case, didn't ask him to come over to do things. The attribute of "can solve cases" is still quite impressive in the grassroots county bureau. Ordinary police officers are willing to work overtime to solve cases, and they will not occupy the time of Jiang Yuan who "can solve cases".

And to talk about it, the fingerprints of the Ding Lan missing person case really only Jiang Yuan can do.

There are too many difficult fingerprints, and the two trace examiners in Ningtai County cannot do them and cannot finish them. If you want to ask for help from trace examiners at the provincial and municipal levels, just based on the missing person case, the case is not qualified.

From a certain point of view, this can also be considered another kind of chicken rib.

Fortunately, Jiang Yuan has no pressure, unlike Wei Zhenguo or Wang Zhong and others, who always have daily tasks assigned, and occasionally extract some free time, they can't pour it all into the case.

Most humans can actually be leisurely if they can be leisurely. If everyone likes to study and work in the cracks, where is the sweating in the red light street, pink hair salon, neon nightclub, and dim clubhouse? Similarly, if everyone likes to study and work in the cracks, where is the sweating in the red light street, pink hair salon, neon nightclub, and dim clubhouse?

Of course, the role of the forensic system cannot be ignored. Even without the assistance of skills, its existence itself makes Jiang Yuan more focused.

Even Wu Jun, looking at Jiang Yuan's work state, couldn't help but evaluate: "When I was young, if I could dissect corpses like you, I would have been transferred to the city bureau long ago."

"Is it better to be a forensic doctor in the city bureau?" Jiang Yuan drank tea and rested his eyes.

Wu Jun thought for a while and said: "The salary is a few hundred more, at least."

Jiang Yuan didn't even blink his eyelids: "Then there is no difference."

"When welfare housing is distributed, the housing distribution of the county bureau is in the county, and the housing distribution of the city bureau is in the city." Wu Jun said, his eyes swept to Jiang Yuan, and suddenly felt a little bored, waved his hand: "For you Jiang Village people, there may be no difference."

"My family doesn't have many houses in the city." Jiang Yuan explained.

Wu Jun laughed, feeling that chatting was quite boring, pointed to the computer screen, and said: "How are your fingerprints doing? If there are clues, let Old Wei check them. Evidence is not necessarily the more the better."

"Another day, the fingerprints that can be done should all be done. Counting the time, it seems to be about the same." Jiang Yuan looked at the notebook twice, took out his mobile phone and called Wei Zhenguo.

Before long, Wei Zhenguo ran up.

Climbing up the four-story staircase in one breath, Wei Zhenguo was a little out of breath, but his expression was very happy, asking: "Any results?"

"Most of them, there are a few that haven't been done, I'll do them again, see how many can be matched tomorrow." Jiang Yuan stapled the few pages he had just printed and handed them to Wei Zhenguo.

On the paper, the first one is a labor reform prisoner.

"Picking quarrels and provoking trouble, fighting and brawling... Good guy, even matched this kind of person, and still don't call?" Wei Zhenguo saw the first one and stopped directly, eager to move.

"Dead." Jiang Yuan gave an irrefutable answer.

Wei Zhenguo's idea was different. He looked down at the record Jiang Yuan made, but frowned instead, saying: "When he left fingerprints, he wasn't dead yet. Ding Lan went missing on March 26th. He had just been released from prison at that time. If this case was committed by him... it might be a dead case."

At this time, Wei Zhenguo regretted looking for Jiang Yuan, wasting so much of his time. If the result was that this road didn't work, he would also be embarrassed.

Jiang Yuan had no experience and didn't think about so many follow-ups, just said: "Look at the back."

"En... picking quarrels and provoking trouble, injury... another one?" Wei Zhenguo noticed the second person matched after a few small paragraphs.

"Also dead." Jiang Yuan added.

"This is not right!" Wei Zhenguo hissed and said: "On a broken bicycle, two dead people's fingerprints fell, and they are all professional criminals?"

As a criminal police officer, Wei Zhenguo had already flashed a series of cases in his mind. Gang crime, uneven distribution of stolen goods, killing people to silence them...

"This person died of cancer. Acute pancreatic cancer, had surgery and chemotherapy, stayed in the hospital for half a year, suffered a lot." Jiang Yuan said: "I specifically called, his mother said."

Jiang Yuan was not completely insensitive, and he said it so detailedly, also to prove that at least the second person had no too many doubts about the death.

Wei Zhenguo sighed, his heart was equally worried. If this person caused Ding Lan's disappearance, it might also cause a dead case.

The third one Jiang Yuan ranked was relatively normal, a young man who had only received administrative punishment and was still alive.

Wei Zhenguo saw this and couldn't help but shake his head: "She is a little girl, how did she know these people."

"Social software." In this regard, Jiang Yuan's adaptability was far beyond Wei Zhenguo, and he said: "I looked at the records you made before, Ding Lan knew several ex-boyfriends, all of whom were met through social software."

"This..." Wei Zhenguo seemed to have returned to the time when the case first occurred. One by one, ex-boyfriends popped up, making the case instantly confusing.

Just a bicycle pushed into the green belt was not enough to track so many clues.

What is even more worrying is that if a crime really happened, the suspect might not have left fingerprints on the bicycle.

As for social software... social software certainly has records, but the trouble of extracting records may exceed the imagination of ordinary people. It's okay to ask for information through online and telephone communication, but many companies do not provide such convenience, but require police officers to go to their jurisdiction and apply for information through the local police station. Because of the need to queue, one business trip often takes one or two weeks.

If you want to check all the mainstream social software on the market, the criminal police squadron of the month doesn't want to do other cases.

From the fourth one, the owners of the fingerprints are relatively ordinary, at least there is no criminal record.

Jiang Yuan extracted as much information as possible from the police pass. His authority was not high, and some were checked through Wu Jun's mobile phone, but the problem remained. It was impossible to see the conclusion from these simple information. Sherlock Holmes might be able to do it, but Jiang Yuan couldn't.

Wei Zhenguo was also looking at his forehead, helpless: "When I opened this case, there were no clues, so I shelved it. Now there are too many clues, and I don't know where to do it. Everyone says that the wind and water turn around, and today it is stuck."

"If there are no particularly prominent clues, then find them one by one." Jiang Yuan did fingerprints like this. In fact, criminal investigation technology is relatively clumsy, and there are very few technologies that make people look at it and feel genius.

Many criminal investigation technologies are even third-hand, or even fourth-hand technologies. From the hall of science to university laboratories, and then to private enterprises and even popular in the industry, will they be introduced into the criminal investigation field.

There are many reasons for this, one of which is that the trust cost in the criminal investigation field is very high, requiring technology to be more mature and stable.

In general, it doesn't matter if it's clumsy. Technology that can stably do things is the technology that the criminal investigation field likes.

Wei Zhenguo just started to accept Jiang Yuan's technology and experienced his means of directly inserting the suspect, and now he was a little trance when talking about the plan of "one by one" finding.

"Investigation is the old line." Wei Zhenguo laughed, touched his oily head, and his eyes became fierce: "Okay, I will deal with these ex-boyfriends." ===== CHAPTER 45 =====
