Chapter 325: Lack of Skills

Zhu Huanguang looked desperately, looked desperately... still could not distinguish the traces of the "new key" that Jiang Yuan said.

But looking at Jiang Yuan's expression, Zhu Huanguang knew that he might not really be deceiving him.

Zhu Huanguang could only shake his head: "This little thief is a bit unreasonable. Rabbits don't even eat grass on the edge of their nests. He can open the lock with a marble hook. He can't beg for food anywhere, but he wants to get food from acquaintances."

Jiang Yuan guessed that he put down his phone and said: "Maybe it's because I'm a newbie. I'm not very skilled at killing people for the first time, but I'm more cautious, so I tried to match the key first, hoping to save time. The skill of matching the key, Maybe it’s a new one...or not very good at it, or just bad luck. At the same time, I put on a hook just in case.”

Zhu Huanguang didn't listen to Jiang Yuan's subsequent judgment and said unexpectedly: "Are you working on a murder case backlog?"

"yes."

"Ah... you... are a bit powerful." Zhu Huanguang also often makes murder case backlogs by comparing fingerprints.

However, even if Zhu Huanguang can often beat the murder case backlog in fingerprint battles, it does not mean that the murder case backlog is easy for him.

The fingerprint battle is a special situation. Technical experts like Zhu Huanguang gathered together to do fingerprints for thirty or forty days in a simple living and working environment and stimulated by healthy competition, looking at more than 100,000 fingerprints. Only with fingerprints can it be possible to match a murder case in the backlog.

There are only 365 days in a year. After a fingerprint battle in the provincial department and a fingerprint battle in the ministries and commissions, a fingerprint expert's energy and energy are basically exhausted.

On weekdays, if you do your own fingerprints, how can you have the intensity of a fingerprint battle? With a little laziness, a few months passed.

It is difficult enough to do fingerprints on a murder case backlog, but it is almost unimaginably difficult to do a murder case backlog by other means.

Zhu Huanguang has been in the criminal police detachment for so many years. It's not that he has never seen people working on the backlog of murder cases. He has actually seen a lot of them, but it is precisely because he has seen so many that you know how difficult this thing is.

There are many backlogged murder cases that have been completed year after year. Some criminal policemen pursue their past cases for two, three, or five years before they find an opportunity to solve the case.

But Jiang Yuan is not from the criminal police detachment, which means that he has started to solve a new murder case.

Zhu Huanguang couldn't help but think of the circumstances of Jiang Yuan's case that he occasionally paid attention to in the past two days, the previous week, the previous two weeks, and last month. He couldn't help but tremble in his heart: Jiang Yuan is really cruel. He has already surpassed the king. .

No matter what was going on in Zhu Huanguang's mind, Jiang Yuan took off his gloves, took out his cell phone, and called Wan Baoming.

Wan Baoming is the deputy director of the Criminal Investigation Center. For the key physical evidence involved in the backlog of murder cases, he not only needs to know but also fix the evidence, and then find someone to take photos, record, etc.

Zhu Huanguang knew the importance of physical evidence as soon as he heard Jiang Yuan call Wan Baoming.

At this moment, his heart felt like a cat scratching his head, and he couldn't help but curiously asked: "Is the case solved?"

"No; where is this?" Jiang Yuan smiled.

Zhu Huanguang was also inexplicably relieved. It would be too uncomfortable if the case was solved while riding on his own face.

Zhu Huanguang said: "It's not easy to learn how to hook marbles. In the past, young thieves who worked for the thieves for several years may not be able to learn the real skills. Especially picking marbles with a single hook requires constant practice."

"The cost of learning something for some people is high, while the cost of learning something for some people is naturally low." Jiang Yuandao.

Zhu Huanguang thought about what Jiang Yuan said and couldn't help but said: "Do you have a choice for the murderer in your mind?"

"It can't be considered a candidate. This case is originally about rich people." Jiang Yuan smiled.

What was set on fire was a warehouse supplying Jianyuan Pharmaceutical. The drugs inside were typical high-value, low-weight commodities.

In such a large warehouse, there were only two people, the female boss and the warehouse manager. As a result, the murderer killed people and burned their bodies without removing any medicine bottles. This is not something that ordinary petty thieves can do.

From this point of view, this case must be committed by an acquaintance, and the life of the female boss is targeted.

Those who went there were most likely the Yuan family from Jianyuan Company. Only they have the need to kill the mistress.

Of course, judging from the analysis of the current crime team, the murderer's goal was to steal, but when he met the female boss and killed someone, he had to cancel the theft plan and flee instead. The traces of the hook in the lock that Jiang Yuan had seen were also their evidence - the warehouse manager's cousin had relevant skills.

It sounds reasonable, but it just makes sense.

An old thief planned to steal something from a warehouse, bumped into a woman who weighed less than 100, and accidentally killed her. This seemed very unprofessional. It is even more unbelievable to kill someone and not continue to steal things, but to run away directly.

The best partner for a gangster to run away is always money. Even if he decides to run away, the right thing to do is to exchange some things for money first, and then run away calmly and happily...

Wan Baoming ran over quickly.

Then, Jiang Yuan told him about the difference between the marks left by a new key and the marks left by a hooked marble.

Wan Baoming didn't understand it very well, but Zhu Huanguang understood it, but because of this, he felt a little bit at the edge of Jiang Yuan's trace test of strength and couldn't help but become silent.

The traces of hooking marbles are familiar to everyone because they come into contact with them frequently. They are the marks left by hooks and pins hooking and pressing on marbles.

The marks of newly-made keys are not so easy to distinguish, especially the marks of newly-made keys that do not fit the holes. Some are too small, some are too thick, and the oversized ones will naturally leave marks when they collide with each other. However, it is easy to confuse them with normal key marks and marks of hook pins. At this time, we have to take into account the time before and after, etc.

Zhu Huanguang listened and watched, and felt that it was difficult for him to distinguish. The pins of the lock core are small, and the size is not fixed. In addition to ordinary pins, there are also wine glass-shaped pins and spiral-shaped pins.

In short, Zhu Huanguang's trace detection ability is enough to do a dojo, but he is not qualified to do a dojo in the screw, and he does not even have the qualifications to understand.

His tool mark identification ability is at best 8-level, and he can't even estimate Jiang Yuan's strength.

Wan Baoming was more direct. He didn't even need to understand. He just listened and said to Jiang Yuan: "Just make your judgment. What should we do next?"

"Find the key." Jiang Yuan said: "This lock was removed from the back of the warehouse. The key is usually in the hands of the female boss and not given to the warehouse manager. There is no such key in the evidence at the scene. You can ask the people around the female boss to see if you can find the key and then determine under what circumstances the key may be secretly matched."

Wan Baoming nodded and said: "In this case, it is very likely that the key was matched and then started. So it is very likely that it was a few weeks before the incident."

"It is very likely." Jiang Yuan nodded and said: "You can investigate the Yuan family to see who can hook the marbles and who can match the keys."

"The Yuan family in Jianyuan?" Wan Baoming was surprised.

"Yeah."

"Even if this female boss is the mistress of Jianyuan's boss... Well, their family does have a motive, but how could the Yuan family learn to hook marbles?"

"People get bored when they have money, maybe they will ask someone to teach them, it doesn't cost much."

"This... well. I always feel a little silly."

Jiang Yuan curled his lips. He said: "Aren't there many rich people learning to fly airplanes and learn to race cars? Especially those who do extreme sports, what can they do with wing suit flying? They are still learning it one after another."

"Okay, it happens that we have someone over there." Wan Baoming looked at the list and called.

According to the standards of the Changyang City Branch, Jiang Yuan's backlog case team has 18 people in a group to investigate a murder case, which is still very suitable.

Scatter them now, and organize them on the spot when they are needed.

Several police officers organized themselves and soon arrived in Qinghe City.

As criminal police of the Changyang City Criminal Police Branch, they don't have to give Jianyuan too much face. In just half a day, Jianyuan's office area was in chaos.
