Chapter 316: Unskilled Technique

Zhu Huanguang looked desperately, looked desperately... still couldn't distinguish the traces of the "newly matched key" mentioned by Jiang Yuan.

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

Zhu Huanguang could only shake his head: "This little thief is a bit unkind. Even rabbits don't eat the grass by their nest. He can already use hook-springs to open locks. Where can't he beg for food? He has to mess with acquaintances."

Jiang Yuan guessed and put down his mobile phone, saying: "It might be because he is a novice. He is not very skilled at killing for the first time, but his personality is relatively cautious, so he tried to match the key first, hoping to save time. The skill of matching keys might also be newly learned... or he is unskilled, or he is unlucky. At the same time, he also put on hooks just in case."

Zhu Huanguang didn't listen to Jiang Yuan's subsequent judgment, only unexpectedly said: "You are doing unsolved homicide cases?"

"Yes."

"Ah... you this... a bit amazing." Zhu Huanguang also often does unsolved homicide cases, by means of fingerprint comparison.

However, even if Zhu Huanguang often matches unsolved homicide cases in the fingerprint battle, it does not mean that unsolved homicide cases are easy for him.

The fingerprint battle is a special situation, including fingerprint experts like Zhu Huanguang gathering together, in a simple life and work environment, under the stimulation of benign competition, doing fingerprints for thirty or forty days in one breath, looking at more than 100,000 fingerprint maps, before it is possible to match a case of unsolved homicide.

A year has 365 days. After a fingerprint battle at the provincial department and a fingerprint battle at the ministry, the energy and spirit of a fingerprint expert are basically consumed.

On weekdays, doing fingerprints by oneself, how can there be the intensity in the fingerprint battle. Being slightly lazy, a few months have passed.

It is difficult enough to do fingerprints for unsolved homicide cases, and it is almost unimaginable to do unsolved homicide cases through other means.

Zhu Huanguang has been in the Criminal Police Detachment for so many years. It's not that he hasn't seen people doing unsolved homicide cases. He actually sees a lot of them, but precisely because he sees a lot, you know how difficult this thing is.

Many unsolved homicide cases are done year after year. Some criminal police officers follow the cases they once had, following them for two years, three years, five years, and then they can find an opportunity to solve the case.

But Jiang Yuan is not a person from the Criminal Police Detachment, which shows that he has started the investigation of a new unsolved homicide case again.

Zhu Huanguang couldn't help but think of the situation of the cases Jiang Yuan did occasionally noticed a few days ago, a week ago, two weeks ago, last month, etc., and his heart couldn't help but tremble: Jiang Yuan is really fierce, he is already the King of Transcendence.

Regardless of the thousand turns in Zhu Huanguang's mind, Jiang Yuan took off his gloves, took out his mobile phone, and called Wan Baoming.

Wan Baoming is the deputy director of the Criminal Science Center. For the key physical evidence involved in unsolved homicide cases, he must not only know it but also fix the evidence, and then find a special person to take photos, record, etc.

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

His heart was like a cat scratching, and he couldn't help but curiously ask: "Case solved?"

"No; where is it yet." Jiang Yuan smiled.

Zhu Huanguang also inexplicably breathed a sigh of relief. If he had ridden on his face and solved the case, it would be too uncomfortable.

Zhu Huanguang said: "Hook-springs are not easy to learn. The little thieves in the past worked for the thief head for several years for nothing, and they might not be able to learn the true biography. Especially single-hook picking bullets, which need to be practiced constantly."

"Some people learn things with high costs, and some people learn things with naturally low costs." Jiang Yuan said.

Zhu Huanguang pondered what Jiang Yuan said, and couldn't help but say: "You have a candidate for the killer in your heart?"

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

The warehouse burned down was the one supplying Jianyuan Pharmaceutical, and 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 keeper. As a result, the killer killed and burned the corpse, and didn't take away any medicine bottles, which is not something that ordinary little thieves or poor thieves can do.

From this perspective, this case must be a familiar perpetrator, aiming at the life of the female boss, and it is very likely to be the Yuan family of Jianyuan Company. Only they have the need to kill the mistress.

Of course, according to the analysis of the current case group, the killer's goal was theft, but he bumped into the female boss, killed someone, and had to cancel the plan of theft and turn to escape. Jiang Yuan had seen the traces of the hooks in the lock, which was also their evidence—the warehouse keeper's cousin had relevant skills.

It sounds a bit reasonable, but it's just reasonable.

An old thief planning to steal from a warehouse bumped into a woman weighing less than a hundred jin, and accidentally killed her. This thing seems very unprofessional. After killing someone, he didn't continue to steal, but ran away directly, which is even more unbelievable.

The best partner for a big boss in the Jianghu to run away is always money. Even if he decides to run away, the correct approach is to take some things to exchange for money, and then he can run away calmly and happily...

Wan Baoming ran over quickly.

Then, Jiang Yuan told him about the difference between the traces left by the newly matched key and the traces left by the hook-spring.

Wan Baoming didn't understand very well, but Zhu Huanguang understood, but because of this, he touched the edge of Jiang Yuan's trace examination strength, and couldn't help but fall silent.

The traces of hook-springs are familiar to everyone because they are often in contact. It is the traces left by hooks and picks hooking back and forth on the bullets, pressing back and forth.

The traces of the newly matched key are not so easy to distinguish, especially the traces of the newly matched keys that do not fit. Some are too small, some are too thick, and the hard collision of oversize naturally leaves traces, but it is easy to confuse with the traces of normal keys and the traces of hook-springs. At this time, it is necessary to take into account the time before and after, etc.

Zhu Huanguang listened and watched, and felt that he couldn't distinguish it. The bullets in the lock core were originally small, and the size was not fixed. Common ones, besides ordinary bullets, also include cup-shaped deformed bullets, and spiral deformed bullets.

In short, Zhu Huanguang's tool mark identification ability can do dojos, but he is completely unqualified to do dojos in the screw, and he doesn't even have the qualification to understand.

His tool mark identification ability is at most at the level of LV2.8, and he can't even estimate Jiang Yuan's strength.

Wan Baoming is more direct. He doesn't need to understand. After listening, he said to Jiang Yuan: "You make the judgment, what should we do next?"

"Find the key." Jiang Yuan said: "This lock was removed from the back of the warehouse. The key was usually in the hands of the female boss and was not given to the warehouse keeper. In the evidence at the scene, there is no such key. You can ask the people around the female boss to see if the key can be found, and then determine under what circumstances the key might have been stolen and matched."

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

"The possibility is very high." Jiang Yuan nodded and added: "You can investigate the Yuan family to see who can use hook-springs and who can match keys."

"Jianyuan's Yuan family?" Wan Baoming was surprised.

"En."

"Even if this female boss is the mistress of the Jianyuan boss... alright, their family members do have motives, but how could Yuan family members learn hook-springs."

"People are very bored when they have money. Maybe they will ask someone to teach them. It doesn't cost much money."

"This... alright. I always feel a bit silly."

Jiang Yuan curled his lips and said: "Are there few rich people learning to fly planes and racing cars? Especially those engaged in extreme sports, what can they do after learning wingsuit flying? Isn't it still learning one after another."

"Alright. I always feel that we have people over there." Wan Baoming looked at the list and made a call.

By the standards of the Changyang City Detachment, Jiang Yuan's Unsolved Case Special Task Force group of 18 people is still very suitable for investigating a homicide case.

They are scattered now, and when they need to be used, they are organized on the spot.

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

As criminal police of the Changyang City Criminal Police Detachment, they don't have to give Jianyuan too much face. In just half a day, they stirred the office area of Jianyuan into a howl.
