Chapter 326

Zhu Huanguang looked desperately, looked desperately... still couldn't 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 be fooling himself.

Zhu Huanguang could only shake his head: "This little thief is a little unethical. Rabbits don't even eat grass by the side of their nests. He can use a hook to open the lock. He can't beg for food anywhere, but he wants to get acquaintances."

Jiang Yuan guessed and put down the phone, and said: "Maybe it's because of the novice. I'm not very skilled in killing people for the first time, but my personality is more cautious, so I tried to match the key first, hoping to save time. The skill of key matching, Might be new too... or not very good at it, or bad luck. Also, wear a hook just in case."

Zhu Huanguang didn't listen to Jiang Yuan's later judgment, but said unexpectedly: "Are you working on a homicide case?"

"Yes."

"Ah...you are... a bit powerful." Zhu Huanguang also often does homicide cases, using fingerprint comparison.

However, even if Zhu Huanguang can often beat the backlog of homicide cases in the fingerprint battle, it doesn't mean that the backlog of homicide cases is easy for him.

Fingerprint battles are a special case.Technical experts including Zhu Huanguang gathered together, in a simple living and working environment, under the stimulation of healthy competition, to do fingerprints for [-] to [-] days at a time, and look at more than [-] fingerprints, and it is possible to compare A homicide case.

There are only 365 days in a year. After a fingerprint battle between the provincial government and the ministries and commissions, the energy of a fingerprint expert is basically exhausted.

On weekdays, if you do your own fingerprints, how can you have the strength in the fingerprint battle.A little slack, and months go by.

It is difficult enough to do the fingerprints of homicide cases, but it is almost unimaginable to do it in other ways.

Zhu Huanguang has been in the criminal police detachment for so many years, it's not that he hasn't seen many homicide cases, he has actually seen quite a few.But it is precisely because you have seen a lot that you know how difficult this thing is.

Many homicide cases are accumulated year after year.Some criminal police chase their previous cases for two, three, or five years before they find an opportunity to solve the case.

But Jiang Yuan is not a member of the criminal police detachment, which means that he has started the investigation of a new homicide case.

Zhu Huanguang couldn't help but think of Jiang Yuan's case that he occasionally noticed in the past two days, the previous week, the previous two weeks, and last month. .

No matter how many times Zhu Huanguang was going through in his 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 homicide cases, he not only needs to know, but also has to come to fix the evidence, and then find a special person to take pictures, record and so on.

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

At this moment, he was scratching his heart like a cat, and he couldn't help asking curiously: "The case is solved?"

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

Zhu Huanguang was also inexplicably relieved. It would be too uncomfortable to solve the case with his own face.

Zhu Huanguang said: "Hooking marbles is not easy to learn. In the past, little thieves worked for the thief for several years, but they might not be able to learn the true teachings. Especially single-hooked marbles, you need to keep practicing."

"Some people learn things at a high cost, while others learn things at a naturally low cost." Jiang Yuan said.

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

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

What was set on fire was the warehouse supplying Jianyuan Pharmaceuticals, and the medicines inside were typical high-value and low-weight commodities.

In such a large warehouse, there are only two people, the female boss and the warehouse manager. As a result, the murderer killed and burned the corpse, but did not take away any medicine bottles. This is not something ordinary thieves and poor thieves can do.

From this point of view, this case must be committed by an acquaintance, targeting the life of the female boss, most likely the Yuan family of Jianyuan Company.Only they have the need to kill the mistress.

Of course, based on the analysis of the case team, the murderer's goal was to steal, but when he met the female boss and killed someone, he had to cancel the plan of stealing and ran away instead.The traces of hooks 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's only reasonable.

An old thief planned to come to the warehouse to steal things, bumped into a woman who weighed no more than a hundred, and accidentally killed her, which seemed very unprofessional.It is even more unbelievable to kill someone and not continue to steal things, but just run away.

Money is always the best running partner for a gangster. Even if he decides to run away, the correct way is to exchange some things for money first, and then he can run calmly and happily...

Wan Baoming quickly ran over.

Then, Jiang Yuan told him about the difference between the traces left by the new keys and the traces left by hooked marbles.

Wan Baoming didn't understand it very well, but Zhu Huanguang did, but because of this, he felt the edge of Jiang Yuan's trace test strength, and couldn't help but fell silent.

The traces of hooking marbles are familiar to everyone because they are often in contact with them. It is the traces left by hooks and pins hooking and pressing on the marbles.

It is not so easy to distinguish the traces of the new key, especially the traces of the new keys that do not fit well, some are too small, some are too thick, oversized head-to-head will naturally leave traces, but it is easy to distinguish Confused with normal key marks, and marks for hooked marbles.

At this time, it is necessary to take into account the time before and after.

While listening and watching, Zhu Huanguang felt that it was difficult for him to distinguish. The pins of the lock cylinder are small in nature, and the size is not fixed. In addition to ordinary pins, there are also deformed wine glass pins and spiral pins.

All in all, Zhu Huanguang's trace detection ability can be used as a dojo, but he is not qualified to be a dojo in snails at all, and he is not qualified to understand it.

His ability to identify tool traces is at the level of LV2.8. [-]. He can't even estimate Lai Jiangyuan's strength.

Wan Baoming was more direct. He didn't even need to understand. After he finished listening, he said to Jiang Yuan, "Just make your judgment. What should you do next?"

"Look for the key." Jiang Yuan said: "This lock was unloaded from the back of the warehouse. The key is usually in the hands of the female boss and has not been given to the warehouse. There is no such key in the evidence at the scene. You can ask the female boss People around you, see if you can find the key, and then determine under what circumstances the key might be stolen."

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

"It's very likely." Jiang Yuan nodded, and said, "You can investigate the Yuan family to see who can hook marbles and who can assign keys."

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

"kindness."

"Even if this female boss is Boss Jianyuan's mistress... Well, the people in their family do have motives, but the Yuan family, how could they learn how to hook marbles."

"It's boring when people have money, maybe they will ask someone to teach them, and it won't cost a lot of money."

"It's... well. It always feels a little silly."

Jiang Yuan curled his lips, and said, "There are few rich people who learn to fly airplanes, but are there few who learn to race cars? Especially those who engage in extreme sports, what can they do after learning wingsuit flying, they just learn one after another."

"Okay, we just happen to have someone over there." Wan Baoming looked at the list and called.

According to the standards of the Changyang City Detachment, a team of 18 people in the Jiangyuan Accumulated Case Team is quite suitable for investigating a murder case.

Sprinkle it now, and organize it on the spot when you need it.

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

As the criminal police of Changyang City Criminal Police Detachment, they don't have to give Jianyuan too much face.In just half a day's work, Jianyuan's office area was disturbed and screamed.
