Chapter 153
Huang Qiangmin didn't go anywhere, and followed Jiang Yuan, scanning the trace evidence at the scene of the corpse, and then climbed upstairs to scan the trace evidence at the scene of the crash.

He didn't work or speak, just followed Jiang Yuan and watched Jiang Yuan do things.

Seeing Huang Qiangmin's figure, Wu Jun and other old detectives gradually felt the pressure doubled.

Huang Qiangmin belongs to the more ideal criminal police.

Although the word ideal is too hypocritical to describe a middle-aged man in his 50s or [-]s, it is occasionally used in the police force.

If there is no ideal, the position of captain of the criminal police will become very painful.

Both mentally and physically.

For example, at this moment, with the mobile phone video, Huang Qiangmin can actually commit suicide and deal with the case first.

Because this is not just a suspected suicide, there is already solid evidence that it is a suicide case

If there is further evidence to prove that it was a homicide, it is nothing more than restarting the case.Jurisprudentially, both are compliant.

If you have no ideals at all and simply consider the worldly gains and losses, closing the case is the most normal decision.

Moreover, it is also the most favorable decision.

Because in this case, if it is not a suicide, it is either a crime with a high IQ, or a case where the murderer is very lucky and the victim is very unlucky.

Regardless of which one, the difficulty of detection is high.

And if it can't be solved, then all the backlog of cases solved this year and the work done for Lin County and Lin City will all be in vain.

If the current murder case cannot be solved, after 300 points have been deducted, and then a passing assessment is given, it will be regarded as a great convenience for the bureau.

However, Huang Qiangmin's ideal country does not allow him to do so.

Therefore, in the eyes of several experienced criminal policemen, Huang Qiangmin was almost reckless waiting for Jiang Yuan to collect evidence.

"Yellow team. Otherwise, let's go back and count up?" A policeman came forward to suggest.

Homicide is still a very serious matter. Whether to file a case or start a case is not something that the criminal police chief can make alone.

And now, if Huang Qiangmin doesn't make a decision, the director and the deputy director in charge of criminal investigation should also appear.

Gao Chuan died abnormally by default.But if the situation is complicated, the director and deputy director will also come as usual.

At that time, Huang Qiangmin has to make a decision and report to the director.

Huang Qiangmin naturally knew the meaning of the following, but he looked at Jiang Yuan and said: "Go to the opposite building and run to all the offices. If there is a public rest area, the surveillance video will also be obtained. Wanghe Building The same goes for the high-level offices, you must go all the way.”

This still means doing it in front of a murder case.

Seeing Huang Qiangmin's resolute attitude, the policemen below stopped talking, turned around and went to work one by one.

Anyway, when the sky fell, there was a tall one holding it up.

Huang Qiangmin took out his mobile phone again and sent out several messages in a row, while continuing to follow Jiang Yuan's pace.

In the final analysis, he still believed in Jiang Yuan.

In terms of the number of cases solved, Jiang Yuan alone has solved more homicide cases than a squadron of policemen.

If the time point is closer, the Ningtai County Criminal Police Brigade must have done more homicide cases in the past 10 years, but the homicide cases in the past five years have not been as many as Jiang Yuan has done.

Jiang Yuan has such strength, others may still hesitate because of his age and experience.Huang Qiangmin watched the whole process.

He has experienced the DNA tide in 03.

At that time, the ministries and commissions had just started to promote DNA. What was the result?
Many police departments can solve a homicide backlog a week.DNA evidence such as rape is particularly easy to obtain, and the average day is not an exaggeration.

How many serial rapists have been caught because of this.

When technological innovation just broke out, the power revealed is enough to make anyone dumbfounded, only to believe in the impact of reality.

In Huang Qiangmin's view, Jiang Yuan's technical strength, at least in Ningtai County, is explosive.

If it is a suicide case encountered this time, that's all.

If it is really a crime with a high IQ, Huang Qiangmin believes that Jiang Yuan's strength can teach him to be a man.

"Yellow team. The director is here." A policeman came to report.

Huang Qiangmin glanced back at Jiang Yuan, seeing that he was still sweeping the scene without distraction, he turned and went to the door.

When we arrived at the place, the director Guan Xi and the deputy director in charge of criminal investigation just arrived.

"What's the situation?" Guan Xi asked as soon as they met, and he had to understand the situation at the scene first.

"A 27-year-old male named Li Jiangshu. Gao Zhui died. According to the information collected so far, he worked for a tourism company in Wanghe Building, an employee of a private enterprise..." Huang Qiangmin spoke quickly, but also relatively briefly. .

Guan Xi listened attentively, and then asked, "How about the way of death?"

"Not sure yet." Huang Qiangmin replied, and added: "There is a video showing that Li Jiangshu jumped from an upstairs window alone. But we think there are still doubts."

"What doubt?" Guan Xi asked directly.

Huang Qiangmin was silent for two seconds, and said, "I'm also waiting for the report."

"En..." Guan Xi actually had his own source of information, seeing that Huang Qiangmin didn't say anything, he couldn't help but smile, and asked, "Jiang Yuan brought it up?"

"Correct."

"You kind of trust him."

"I have to believe it." Huang Qiangmin showed a wry smile instead.

Guan Xi was taken aback for a moment, but also laughed.

As a leader himself, he suddenly understood Huang Qiangmin's mentality.

In fact, if you translate it, it is a very simple scene.

Huang Qiangmin is a Chinese teacher and invigilates the math test.At this time, the strongest student in the class pointed out that there was a mistake in the third question on the math paper, and the four options ABCD were all wrong.

Although it is also a very small probability event, can you not report it?

If you can't read it by yourself, don't you have to wait for Xueba, or more information from above?
"Then let's deal with it as a murder case." Director Guan Xi was actually less stressed than Huang Qiangmin.

Huang Qiangmin is in charge of criminal cases throughout the county.It is his responsibility to detect murder cases, the eight major categories of serious cases are his responsibility, and the detection rate of cases in the whole county is also his responsibility.

But for the bureau chief, his most important responsibility is actually maintaining stability.

Since Huang Qiangmin decided to support Jiang Yuan, Guan Xi also recognized it and helped him further straighten out the relationship.

Huang Qiangmin really expressed his gratitude, and said: "Then let's expand the investigation first, and if we can confirm that it is a murder case, we will file a case..."

Excluding the judgment of suicide or homicide, this case is nothing more than a high-profile fall.

Gao Chuan's case, even if it is a murder case, everyone has done a lot.

The policemen of the criminal police brigade acted quickly.

The inquiry that should be asked, the transcript that should be made, and the one that is too late to do, also write down the mobile phone number, take a photo, and do it later.

The three squadrons scattered out, facing the four buildings and a circle of podium buildings, and quickly disappeared without a trace.

Jiang Yuan didn't hear anything outside the window, so he focused on collecting evidence.

In fact, he didn't know what he had collected, and modern technology hadn't developed to the point where he had all kinds of micro-evidence detection instruments with him.

However, like Huang Qiangmin, he was also somewhat aware that what he was facing might be a windmill, or it might really be a formidable enemy with complete armor.

The so-called high IQ crimes actually rarely appear in the domestic criminal investigation environment.

Guys like Tan Yong are already very meticulous criminals.

As for the guy in the Baiyin case, the complexity of the case is at most sixty or seventy.He is the type who has many flaws, but he still can't catch them.

But from another perspective, if a person conspires to commit a crime, he must be well-prepared and thoughtful.

Although most criminals thought so ridiculously that they were caught at the rookie stage.

But is there someone who got away with luck in the first or second premeditated crime, gained experience, and continued to commit crimes?

Perhaps, the fact that such people are rarely caught is the real problem.

Jiang Yuan has no criminal investigation experience.

If you want to evaluate his own criminal investigation skills, LV0.5 is already considered a very high evaluation.

In terms of arresting ability and case-handling level, there can be no more than LV0.3.In this regard, he is basically useless.

But Jiang Yuan knew that it would be very difficult for any criminal, even a really high IQ criminal, to clean up the scene.

Especially in public places like this.The more time you spend, the more information you leave behind.

The classic Locard principle talks about this: the process of crime is actually a process of material exchange. As a material entity, the perpetrator always communicates with various material entities in the process of committing a crime. Contact and exchange relations take place...

Crime will inevitably produce physical evidence. In the investigation of the crime scene, if no physical evidence left by the perpetrator is found, it can only mean that no physical evidence was found, but it cannot be said that there is no physical evidence at the scene.

Jiang Yuan's crime scene investigation ability is very strong, and because of this, he is more willing to use a comprehensive inspection to prove the nature of the case.

rather than draw conclusions about it.

Wu Jun finished his work, followed Jiang Yuan, and soon his cervical spine waschemic with his head bowed.

Seeing Jiang Yuan rubbing vigorously at the scene of the crash, Wu Jun said, "Why don't I send the body to the funeral home first."

"Okay, I'll go later." Jiang Yuan only responded, and buried his head in wiping again.

Wu Jun coughed twice, had no choice but to ask Huang Qiangmin for a stronger policeman, and left with him.

Jiang Yuan wiped like this until it was dark, and only left the scene when the people in the building were almost gone.

When leaving, Jiang Yuan and the accompanying policemen walked into the elevator. Because there was no one in the corridor, the lights went out one by one. Only the yellow light in the fire exit was on, which looked quite intrusive.

　It’s early morning again, my schedule collapsed, meow
