Dong Bing sent Jiang Yuan and others to the guest house of the municipal bureau, arranged the room, and immediately went to find Wu Xia, an expert from the province.
Wu Xia is 50 years old, has a square face and a somewhat dignified image. He is also a long-established fingerprint expert in Anping Province.
Dong Bing had dealt with Wu Xia before. He knocked on the door, but without closing it, he went inside and said: "Military team, I have brought over the fingerprint experts and trace inspection experts from Shannan Province."
"The one you picked up is Jiang Yuan, right? Jiang Yuan from Ningtai County?" Wu Xia asked.
"Yes, do you know him?"
"I don't know anyone. I've never seen anyone."
"Then I think you should pay attention." Dong Bing curled his lips and said: "He is quite grand, he is young, and he brought seven or eight people here in one go. It feels like he is bringing people here for a vacation. Listen.
When he spoke, he didn’t seem too confident..."
Wu Xia interrupted Dong Bing and said, "He has solved more than 20 murder cases this year."
Dong Bing was stunned: "What do you mean?"
Wu Xia looked at Dong Bing, smiled, and said: "He is a great person. This Jiang Yuan participated in the fingerprint competition in their province. In a little over a month, he won 10 murder cases."
Everyone who heard Dong Bing was a little stupid: "10 murder cases in the backlog? How is that possible? Didn't all the fingerprint experts in their province do anything before?"
"It depends on what you said. That's a long list of murder cases. How could someone get away with it?" Wu Xia's tone became slightly harsher, then softened and said: "If you don't tell us, you can't underestimate the world's heroes.
Well, you are looking at people’s youth. Do the math, how many murder cases does a criminal police brigade in your city bureau solve in a year? How many backlogged murder cases can be solved in a year?”
Dong Bing's expression stiffened. This is incomparable. Guqi City is not a big city. There are few homicide cases and there are not many backlogged cases. A criminal police brigade can only handle three to four murder cases throughout the year. Normally,
There are other jobs. And if there is a backlog of fortune-telling cases, there are even fewer. Most of the brigades are not eligible for this job.
"Does that mean he's pretty awesome?" Dong Bing whispered.
"He's better than me anyway." Wu Xia said directly.
Dong Bing quickly smiled and said: "Then you are too humble..."
"Nothing to be modest about. I heard that the ministry invited Jiang Yuan, so I immediately looked for his fingerprints that had been compared. There was nothing to say... Well, you can take a look too." Wu Xia said.
, and opened the previously organized folder on the computer.
Dong Bing had no choice but to go over and take a look, saying, "I can't read fingerprints either..."
"You can understand this at a glance."
Dong Bing turned around the laptop and saw a black lump on the screen.
Dong Bing looked at Wu Xia in confusion.
"This is the fingerprint of one of the cases. Is it an exaggeration?" Wu Xia said, shaking his head with emotion.
Dong Bing hissed: "If you didn't say it was a fingerprint, I thought it was the ash at the bottom of the pot."
"It's almost the same thing, but people are surprised that they can use Photoshop and other image software to scrape out the bottom of this black pot." Wu Xia sighed twice, looked at the computer screen again, then shook his head and said: "Actually, I don't either.
If you study it too carefully, there will be nothing to study. This is what the ancestors rewarded you with, and I can’t even learn it, and I can’t learn it.”
"You are too humble..." Dong Bing quickly comforted him, but in terms of his inner feelings, Dong Bing actually agreed with Wu Xia's words. A fingerprint expert like Wu Xia, who is capable of making mistakes, is not as normal as Wu Xia.
The level of provincial experts is still very different.
"Experts hired by ministries and commissions, no joke... By the way, have the conference rooms been arranged? You can go back and ask Expert Jiang if there are any special needs. I estimate that fingerprint and trace inspection experts of this level will be suitable for
There are still requirements for the working environment, at least there must be a computer for image processing." Wu Xia was knowledgeable, and as he spoke, he indirectly guided Dong Bing's work.
Dong Bing nodded repeatedly and said hurriedly: "Then I will prepare things first. We may organize an expert discussion meeting in the evening. The latest news and progress will be updated then. Please remember to attend."
Even if the experts come from all over the country and work very hard, it is impossible to get a full rest in a criminal case like this.
The timeliness requirements for criminal cases are too high. No matter how good the expert is, he has to give in when faced with the golden 24 hours or the golden 72 hours.
Jiang Yuan and others basically only got twice the time to wash up and change clothes. After packing up, they only took a short rest before being told to go to the conference room.
Soon, five experts coordinated by the ministry and three experts from Anping Province gathered together.
Gao Changjiang, director of the Guqi Municipal Bureau, entered the conference room with a serious look on his face.
"Expert Jiang is here?" Gao Changjiang recognized Jiang Yuan at a glance, or in other words, he noticed a few more people.
"Yes, we just arrived." Jiang Yuan sat up straighter.
Gao Changjiang said "En" and said: "Then you should familiarize yourself with the situation as soon as possible and keep up with the progress. Well, is Professor Shi Hao here?"
Jiang Yuan raised his eyebrows. Shi Hao was a famous trace expert in China, and he had heard of his name.
Dong Bing stood up and said: "Professor Shi Hao's case is not over yet, so he won't be able to arrive tonight."
"Then let's have a meeting first. Let me report the situation first. According to our expanded investigation today and the release and collection of information, the number of missing children has increased to 4. In just half a month, 4 children were taken away
Children, the severity of the case is shocking!" Gao Changjiang first commented, then looked at both sides, and then said: "With today's day's follow-up and follow-up, there are no existing clues that can further advance the case. I am now
Consider whether it is necessary to re-examine the evidence..."
When Jiang Yuan was on the plane, he read some case information. He just reviewed today's progress and it was easy to understand Gao Changjiang's words.
No clue is the current progress.
Disappearance cases are inherently extremely difficult to solve.
It's not like a murder case. There will be at least one body as a clue for the police to track. In addition, there is often no strong causal relationship between the perpetrator and the victim of the disappearance case.
Especially in the cases of missing children, the criminals usually abduct or kidnap for the purpose of buying and selling. In other words, the criminals are committing crimes against a specific group of people. He is not necessarily arresting any child, but has a certain degree of randomness.
Take action. This increases the difficulty of detection in disguised form.
Finally, criminals in missing persons cases tend to move around. It is most common to change places by shooting, which adds another level of difficulty to the investigation of the case.
Therefore, the police do not like to deal with disappearance cases. Not only are they worried that the missing person will come back on his own, but the difficulty of the case itself is also very high.
At this point, disappearance cases and poisoning cases are similar in that they both rely heavily on surveillance or witnesses.
This case lacks the support of these clues.
"The vegetable market on Erma Lane is currently the place where the most children are lost. However, there are no clues yet in the investigation of the hotels, restaurant service industry, and rental market near Erma Lane."
"The good news is there are no reports of bodies at this time."
"But there is no information on human trafficking of children either."
"The search of transportation vehicles and surveillance during the incident found nothing."
"We plan to focus on searching the Erma Lane area starting tomorrow morning, and have also deployed police dogs."
Gao Changjiang's anxiety was palpable. As he said, this case was too bad, but there was no progress at all.
For now, he does not need to hold a press conference, but he must report the situation to the leadership. As far as the case is concerned, his report can only be K.
Jiang Yuan slowly flipped through the files.
The only disappearance case he ever worked on eventually turned into the case of a girl imprisoned in Changyang City.
Although the case has been solved, in retrospect, Jiang Yuan can still recall all the difficulties he encountered that day.
Speaking of which, in that case of disappearance, there was at least one bicycle for analysis. But in this case of disappearance in Guqi City, there was nothing left behind.
"Searching Erma Bridge may not necessarily be useful. The criminal has made careful preparations here, so he should not be troubled by the problem of residence." An expert put forward an opinion: "Is it possible to keep Erma Bridge and assign some manpower?
, enter the market in disguise..."
Gao Changjiang shook his head: "We have waited long enough. The criminal must have known about our involvement. Now... it's time to show the sword clearly."
"Are these just the cases?" Jiang Yuan looked down and asked, "Are there any similar cases before?"
"We have checked the cases in the past two years and there are no similar cases." Gao Changjiang shook his head slightly.
"Judging from the traces at the scene, the criminal knew what he was doing and left very few traces. This was definitely not the work of a novice." Jiang Yuan raised his voice slightly, causing everyone to frown.
