National Forensic Doctor

The video of Wang Futing's interrogation was very long and repeated many times. It was quite complicated and even a bit tiring to watch.

The interrogators also paid a lot of attention and provided Wang Futing with almost two boxes of cigarettes.

Talking about death while holding a cigarette is the last romance for male prisoners.

Later, the branch leader frowned and commented: "No regrets!"

Tao Lu spoke beside him: "He climbed out of the underworld. He has been involved in society since he was a teenager. He also worked with Pan Renwu, the one who was shot to death in the late 1990s. Everyone who played with him was shot twice. ”

"You didn't even shoot him?"

"Those who survive must be lucky. He has become the vice president of Duanda, and there are many people with Lu Qiang, many of whom are older than Wang Futing. In the end, he was given a position such as director. He plays with women every day in different ways.”

"Why is he so lucky?" As a leader, I know how difficult it is to get promoted, but I don't believe in hard work.

Tao Lu was stunned for a moment by the question, thought for a moment, and then tried again: "Maybe he has a more flexible personality. As far as I know, Wang Futing was relatively good at communicating when he was in the world. When he was young, he worshiped I followed several masters, followed several bosses, and later followed Lu Qiang. I also changed from a bandit leader to a demolition manager. He was very good at demolition matters. He was very familiar with tricks such as coercion and inducement. He was not just a mere person. "Those who do things by force."

"Know how to assess the situation." The leader nodded, accepting this logic.

"Your summary is very apt..." Tao Lu quickly output the emotional value, commonly known as flattery.

"Well, no wonder." The leader suddenly understood Vice President Wang Futing. If you can speak well, have a field of work that you are good at, and can especially meet the spiritual needs of your superiors, this is the model for promotion.

The other police officers watched the video and each had their own ideas and discussed in low voices.

Wang Futing gave up completely, so he talked a lot.

But so much information is from more than 20 years ago. How much of it can be used has become another problem.

There are also some police officers who doubt the authenticity of Wang Futing's testimony - this doubles the difficulty. For the same reason, it is very difficult to falsify many testimonies in cases more than 20 years ago.

"I'm going to study the claws Wang Futing mentioned." Jiang Yuan watched Wang Futing's video and felt a little sleepy, so he simply yawned.

At the same time, his emotional intelligence was almost offline.

Song Tiancheng asked from the side: "Where is the direction of the investigation? Do we need to determine it first?"

"I would like to ask Liu Chu to come over and take a look before we talk." Jiang Yuan shook his head. There was too much evidence that Wang Futing confessed, and it was difficult to tell whether it was true or false. This was not Jiang Yuan's expertise, and it was too much of a waste of his time.

Song Tiancheng hesitated for a moment. Although he also knew Liu Jinghui from Shannan Province, by national standards, Liu Jinghui was obviously not as famous as Jiang Yuan. However, Song Tiancheng could also understand that there was a specialization in the art industry, and he was familiar with Jiang Yuan's case-solving process, so Song Tiancheng just acquiesced and remained silent.

Tao Lu saw Song Tiancheng's uneasiness and said clearly: "Liu Chu's remote assistance was quite smooth before. Do you want to call him over? Can you walk away?"

"He dismissed the subsequent cases, but he wanted to repay Liu Chu's favor later." Jiang Yuan said, and added: "There are too many case files now, and most of the photos and the like are on film. Remote assistance may not be possible." It’s easy to operate.”

In the case of the late 1990s, crime scene photography was still done by professional criminal photographers, and the cameras used were film cameras. A roll of Kodak film cost more than 20 yuan. Even if your unit had a darkroom for development and printing, just take a picture. The average cost of a photo is also a dollar.

Therefore, 10 years later, the custom of taking photos without worrying about missing out or taking more photos did not exist in the police station in the late 1990s.

Weaker police stations, such as the Ningtai County Bureau, may not keep photos of an ordinary theft case. Only major cases can be allocated thousands of photos - because there are many homicides, the funds that can be allocated for handling cases, especially for photography, are naturally limited, and some murders will become ordinary homicides.

For criminal photographers of that era, the low-end value was to complete the set shooting tasks, the mid-range value was to use as little money as possible to give a complete picture of the crime scene and the characteristics of important evidence, and the high-end value was to accurately restore the truth.

In the Jianmenyuan case, criminal photography experts were also invited to take photos. This is also the advantage of being in the capital. In terms of film and shooting skills, the Beijing Bureau did not save money back then.

But after so many years, it is normal that some photos have faded and some negatives cannot be developed. Liu Jinghui is about to come over and read it again.

After all, Jiang Yuan's requirements for him are different from his requirements for himself.

When Jiang Yuan investigates cases by himself, he is essentially looking for evidence. Finding criminal suspects through evidence is his underlying idea.

According to Liu Jinghui, although the murderer can often be found through simple reasoning, the case of Jianmenyuan requires rigorous reasoning anyway.

Theoretically, even if he can find the murderer through simple reasoning, the Zhang family still needs to see comprehensive and rigorous reasoning to prove that Zhang Xiaoming's murderer is indeed the person.

But the reality is that after repeated research on Jianmenyuan's cases, there is no possibility that simple reasoning can solve the case.

However, this case is indeed attractive to Liu Jinghui.

The more people have studied the backlog of cases and the more experts have participated in the backlog of cases, the more valuable the case will naturally appear. Liu Jinghui had given up on promotion a long time ago. Solving crimes was his greatest pleasure.

early morning.

When Liu Jinghui arrived at the compound of the Criminal Police Detachment of Zhengguang Bureau, he happened to catch up with the regular meeting of the Jianmenyuan task force.

This was also the first regular meeting after the official restart of the Jianmenyuan task force. There were so many people attending that those who spoke had to hold a microphone to speak.

The regular meetings are mainly about briefings, and there are basically no special discussions.

As the saying goes, small meetings decide big things, and the general meeting decides small things. It is basically impossible to have effective discussions in such a large-scale meeting.

After the meeting, Liu Jinghui went to Jiang Yuan again and saw two files in front of Jiang Yuan. They were very thin. Liu Jinghui subconsciously frowned.

"Is this the result of your research on the flying claw?" Liu Jinghui knew Jiang Yuan's strength too well. Tool mark identification is a centuries-old technology, but not many can do it well, and there are too few who can do it as well as Jiang Yuan.

Typical tool mark identification is like having a gap in a kitchen knife. You used it to kill the neighbor's eldest son and then the neighbor's second son downstairs. The police compared it and found that the gap was correct. Then It was probably cut with a knife.

Of course, it is possible that the knife that killed the second child may have more cuts. This is also a part of tool mark identification.

From Liu Jinghui's understanding, Jiang Yuan would definitely make great discoveries about such a rare weapon as the Flying Claw.

Jiang Yuan patted the two files in front of him and said, "I'm a little surprised too, but after searching, I found only two cases, which have something to do with this flying claw."

"In so many years, there have only been three cases of using flying claws in the country?" Liu Jinghui couldn't believe it.

Jiang Yuan shook his head: "Flying claws and flying claws are also different. This thing is very difficult to build. As far as I know, those who can use it skillfully will not easily replace the flying claws. Therefore, although the murderer may have been involved in another Two cases, but as far as we know, there are only three cases in total.”

"Impossible." Liu Jinghui shook his head without thinking: "Unless you don't use it, but who would learn the trick of flying over the wall and not using it. I originally thought that through flying claws, it would be possible to solve the case."

"It seems we can't." Jiang Yuan spread his hands: "Moreover, the other two cases are also theft cases, involving smaller amounts."
