Chapter 44: Ex-Boyfriends

For two consecutive days, Jiang Yuan has been concentrating on handling fingerprints in the Ding Lan case.

Because he has solved several cases in succession, including a murder case that has attracted the attention of the whole system. Jiang Yuan's rookie attribute has been almost washed away, or in other words, it is shining.

Now, at least in the Ningtai County Bureau, most people have heard of the name "Jiang Yuan".

The most direct impact brought about by this is that no one will ask Jiang Yuan to do odd jobs.

Even Wu Jun, seeing Jiang Yuan busy with fingerprints in the case of Ding Lan's disappearance, did not ask him to come to work. The attribute of "being able to solve cases" is still very impressive in grassroots county bureaus. Ordinary police officers are willing to work overtime to solve cases, and will not infringe on the time of Jiang Yuan, who is "able to solve cases".

And to be honest, only Jiang Yuan can do the fingerprints in the case of Ding Lan's disappearance.

There are too many difficult fingerprints, and Ningtai County's two trace detection officers cannot do them or finish them. If they want to seek help from trace detection at the provincial and municipal levels, the case is not qualified if they only use the missing case as the basis.

To some extent, this is also a kind of chicken rib.

Fortunately, Jiang Yuan has no pressure. Unlike Wei Zhenguo or Wang Zhong, there are always daily tasks assigned to him. He can't spend all his free time on the case.

Most humans can relax when they can. If everyone likes to study and work whenever they can, there will be no sweating in the red light street, pink hair salon, neon nightclub and dark club. Similarly, if everyone likes to study and work whenever they can, there will be no sweating in the red light street, pink hair salon, neon nightclub and dark club.

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 working state, couldn't help but comment: "When I was young, if I could dissect corpses like you, I would have been transferred to the city long ago."

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

Wu Jun thought for a moment and said, "The salary will be several hundred more, at least."

Jiang Yuan didn't even blink: "That makes no difference."

"When the welfare housing was distributed, the housing allocated by the county bureau was in the county, and the housing allocated by the municipal bureau was in the city." Wu Jun said, and glanced at Jiang Yuan, and suddenly he felt a little bored, and waved his hand: "For you Jiangcun people, it may not make any difference."

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

Wu Jun laughed and felt that chatting was boring. He pointed to the computer screen and said, "How is your fingerprint? If there is any clue, let Lao Wei check it. Evidence is not the more the better."

"In another day, all the fingerprints that can be made should be made. Calculating the time, it seems to be about the same." Jiang Yuan glanced at the notebook again, took out his mobile phone and called Wei Zhenguo.

After a while, Wei Zhenguo ran up.

After climbing four flights of stairs in one breath, Wei Zhenguo was a little out of breath, but his expression was very happy. He asked, "Are there any results?"

"Most of them, there are a few that have not been done. I will do it again and see how many I can match tomorrow." Jiang Yuan stapled the pages that had just been printed and handed them to Wei Zhenguo.

The first person on the paper was a labor camp prisoner.

"Provoking trouble, fighting... Good guy, you have already matched this kind of person, why don't you call?" Wei Zhenguo saw the first one and stopped directly, ready to move.

"Dead." Jiang Yuan gave an irrefutable answer.

Wei Zhenguo had a different idea. He looked down at the record made by Jiang Yuan, frowned, and said, "When he left his fingerprints, he was not dead yet. Ding Lan disappeared on March 26. He had just been released from prison. If he committed this case... it might be a murder case."

At this time, Wei Zhenguo regretted looking for Jiang Yuan. He wasted so much of his time. If this road did not work out, he would be embarrassed.

Jiang Yuan had no experience and did not think about the follow-up. He just said, "Look at the back."

"Well... provoking trouble, hurting... another one?" Wei Zhenguo noticed the second person who was compared after a few paragraphs.

"He is dead too." Jiang Yuan said again.

"This is not right!" Wei Zhenguo hissed, saying, "Two dead people's fingerprints were left on a broken bicycle, and they were all professional criminals?"

As a criminal policeman, Wei Zhenguo had a series of cases flashing through his mind. Gangs committed crimes, unequal distribution of spoils, murder to silence witnesses...

"This man died of cancer. Acute pancreatic cancer, underwent surgery and chemotherapy, and was hospitalized for half a year. He suffered a lot." Jiang Yuan said: "I called specifically, and his mother said so."

Jiang Yuan is not completely insensitive, and he said so much in detail, also to prove that at least there are not too many doubts about the death of the second person.

Wei Zhenguo sighed, and he was worried in his heart. If this person caused Ding Lan's disappearance, it could also cause a murder.

Jiang Yuan ranked third, relatively normal, is a young man who has only received public security punishment, and is still alive.

Seeing this, Wei Zhenguo shook his head: "She is a little girl, how did she know these people."

"Social software." In this regard, Jiang Yuan's adaptability is far beyond Wei Zhenguo, and he said: "I read the records you made before, and Ding Lan met several ex-boyfriends through social software."

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

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

What is more worrying is that if there is a case, the suspect may not leave fingerprints on the bicycle.

As for social software... Social software certainly has records, but the trouble of extracting records may be beyond the imagination of ordinary people. It is okay to get information through the Internet and phone calls, but many companies do not provide such convenience. Instead, the police need to go to their jurisdiction and apply for information through the local police station. Because of the queue, a business trip often takes one or two weeks.

If you want to check all the mainstream social software on the market, a criminal police squadron will not be able to do other cases that month.

Starting from the fourth place, all the fingerprint owners are relatively ordinary, at least they have no criminal record.

Jiang Yuan extracted as much information as possible from the police communication. His authority was not high, and some of it was queried through Wu Jun's mobile phone, but the problem remained. If you want to see the conclusion from these simple information, Sherlock Holmes may be able to do it, but Jiang Yuan can't do it.

Wei Zhenguo was also very anxious, and said helplessly: "When I opened this case, there were no clues, so I put it aside. Now there are too many clues and I don't know where to go. It is said that feng shui turns around, and today it is stuck."

"If there are no particularly outstanding clues, then look for them one by one." Jiang Yuan did this when he did his own fingerprints. In fact, the technology in criminal investigation is relatively clumsy, and there are few technologies that make people feel genius at first sight.

Many criminal investigation technologies, even third- or fourth-hand technologies, or even fourth- or fifth-hand technologies, have become popular from the halls of science to university laboratories, and then to private enterprises and even within the industry, before someone will introduce them into the field of criminal investigation.

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

In general, it doesn't matter if you're a little dumb. The technology that can get things done steadily is the technology that the criminal investigation field likes.

Wei Zhenguo just started to accept Jiang Yuan's technology and experienced his method of directly attacking suspects. Now when he talked about the solutions he found "one by one", he was a little dazed.

"Investigation is my old profession." Wei Zhenguo laughed, touched his oily hair, and his eyes became fierce: "Okay, I'll deal with these ex-boyfriends."
