"The robbery is for you, do you dare to take it?"

Faced with such an inquiry from Lee Wan-kyu, Kim Yun-ho chose to remain silent.

Li Wankui leaned forward, stared at Jin Yunhao with sharp eyes, and asked again, "What?" Can't? ”

Kim Yunhao explained: "I don't know the details of the case, and I don't have the confidence to make a military order. ”

Li Wankui waved his hand: "You go to the scene now to understand the situation, I am here to wait for your answer." ”

Kim Yoon-ho didn't speak, nodded and left immediately, leaving a whisper behind him.

After walking out of the conference room, Kim Yunhao immediately called Yoon Guohong and informed the investigation team to rush to the scene to converge.

Subsequently, he called Song Eunzhi and asked him to investigate the detailed background information of the three robberies.

In the end, he hesitated for a moment and called Chen Geng again. When it comes to homicides, forensic professional advice is required.

Although he didn't want Chen Geng to participate in his work anymore, there was no replacement around him for the time being, so he still dialed the number.

――

At 12 o'clock in the evening, Kim Yun-ho drove to the scene of the murder.

After getting out of the car, Kim Yun-ho carefully looked at the surrounding environment and frowned.

It is located at the intersection of Yangchuan District and Jiulao District, and there are many construction sites nearby, the road conditions are also relatively complicated, and the monitoring has also been demolished, which inadvertently increases the difficulty of handling the case.

Was it accidental, or was the criminal deliberately taking advantage of the special circumstances?

These circumstances are unknown, but Kim Yoon-ho vaguely smells something unpleasant.

After approaching the cordon, the police officer in charge of the guard did not need to show his work ID to Kim Yun-ho, and he was directly saluted and released.

Recently, Kim Yunhao has frequently reported that his appearance has long been known to South Koreans.

Also within the judicial system, the police know Kim Yun-ho better.

No, as soon as Kim Yoon-ho appeared. was recognized, and it caused a whispered discussion.

Kim Yun-ho ignored these, and after walking into the single-family courtyard, the person in charge of the scene ran over after receiving the news.

"Hello! I'm the person in charge here. ”

Kim Yunho returned a salute and said lightly: "Let's introduce the situation." ”

From the mouth of the officer in charge at the scene, Kim Yun-ho learned the basic facts of the case.

The house is in the heart of the demolition. It's all around the construction site.

The male owner of the house is named Kong Dongsheng, 52 years old; The hostess's name is Choi Young-sook, 50 years old, and she has no children.

The husband and wife died on the first floor at the same time, and preliminary observations at the scene showed that the cause of death was a gunshot wound, and the exact time of death could not be judged for the time being, but it was roughly inferred to be between 20 and 22:30 in the evening.

The informants, who were the first to arrive at the scene, were two nearby patrol police officers. They found that the outside door was wide open. I came in to check the situation and found the owner and his wife dead at 22:30.

And before that, the two of them patrolled for the first time at 20 o'clock at this time, and happened to meet the owner and his wife returning home.

The scene was messy, clothes were everywhere, and it was clear that the room had been turned over and cash and jewelry were suspected to have been robbed.

Judging from the situation at the scene, this is a typical burglary.

The only special thing is. The criminals used firearms.

South Korea does not allow citizens to own handguns, only shotguns and less than 400 rounds of live ammunition; and small airsoft guns with a caliber of less than 5.5 mm.

Two previous shootings. All of them were confirmed to be made by modified airsoft guns.

Kim Yoon-ho has roughly inspected the body, and this shooting is also like a modified air gun.

The male deceased, Kong Dongsheng, was shot in the head and fell at the door of the room, presumably killed by a single shot.

The female deceased, Choi Young-sook, was also shot in the head and collapsed in front of the dresser in the bedroom, the only difference is. The area around the body was messy, with broken glass and clothing everywhere.

The shards of glass on the floor came from the mirror above the dresser, and initial observation revealed that it should have been damaged by gunfire, and there were several very dense bullet holes in the wall.

Technicians have already taken out the warhead. I took it for testing.

After inspecting the on-site environment in detail, Kim Yun-ho and others came to Yoon Kook-hong, Shin Dong-hae and Park Ji-tian.

Yin Guohong said calmly: "Chief Jin, we are here." ”

Shen Donghai said impatiently: "Boss, what's the situation now?" Are we in charge of this case? ”

Park Zhitian didn't say much, just bowed down to say hello.

The three of them behaved very differently, Yoon Guohong was calm and sophisticated, Shin Donghae was frizzy and impulsive, and Park Zhitian was cautious.

The three have their own characteristics and can complement each other's shortcomings.

After Jin Yunhao greeted the three of them, he instructed: "You go and check the situation at the scene, whether this case will be taken over by us still needs to be discussed, let's make some preparations first." ”

"Got it." The three of them spoke in unison, no phone bill, and went straight to work.

Not long after, Chen Geng and his assistant Han Yarou also arrived.

I haven't seen him for a long time, Chen Geng is still the same, cold and arrogant, with an expression that is not happy to look at anyone.

"What the hell is it that deserves to call me out so late?"

Chen Geng's tone was very impulsive, and he didn't look at Jin Yunhao when he spoke.

Jin Yunhao didn't care about Chen Geng's attitude, and replied directly: "Shooting? Two deceased. Do you want to get involved or not? ”

Hearing the word gunshot, Chen Geng's eyes immediately lit up, and he immediately changed his equipment without Jin Yunhao's urging.

"It's a shooting! Damn, why didn't you say it earlier! Chen Geng complained, and at the same time urged Han Yarou: "Hurry up, hurry up and help me wear it, I can't wait." ”

Han Yarou is still the same, gentle and elegant, and whispers softly: "I know, I know." ”

The only difference is that it seems that her proud career line is more obvious, and her development is getting better and better.

After Chen Geng and Han Yarou changed their equipment, they walked into the house with Kim Yunhao.

When the corpse was examined, it was still an old habit, Chen Geng led the inspection, and Kim Yunhao listened to the results on the side.

After the formal work, Chen Geng's cloudy eyes disappeared and became extremely focused.

Ten minutes later, Chen Geng had his first test result.

"The cause of death of the male deceased Kong Dongsheng was a gunshot in the skull, and he was killed by one shot, and the preliminary judgment is that one-third of his skull was shattered by bullets. This can prove that the killer was shot at close range.

Judging from the stiffness of the corpse, the time of death should be around 22 o'clock.

In addition, judging by the wound area and blood splattering. The bullet should be a common lead bullet and be about the same shape and weight as a regular pistol bullet.

In this way, it can be inferred that this air gun is extremely powerful and cannot be modified by ordinary people. ”

After reporting the results of the corpse test, Chen Geng turned his head to look at Jin Yunhao and said very seriously: "According to my experience. This is no ordinary shooting.

Ordinary people would not transform the airsoft gun so professionally, and the murderer shot at close range, and he should be very calm, which should not be done by ordinary people. ”

Kim Yunho didn't comment, but nodded, his eyes deep and thoughtful.

Chen Geng didn't say much to Kim Yunhao, and then began to test the second body.

But this time, I didn't wait for the test. After Chen Geng saw the corpse for the first time, he sighed.

Kim Yun-ho asked, "What's wrong?" ”

Chen Geng didn't answer, shook his head, squatted down and started working.

This test took a little longer, and after more than ten minutes, Chen Geng had the results.

"The female deceased, Choi Young-sook, died at around 22 o'clock, and the cause of death was also a gunshot in the skull. Killed by one shot. But after she died, the killer shot her several times. ”

After listening to Chen Geng's report. Kim Yoon-ho immediately asked, "How do you judge the order in which the murderer fired?" ”

Chen Geng smiled confidently and explained: "It's very simple, because of the blood splattering situation.

There are three main fatal causes of gunshot wounds: First, lead bullets are poisonous, and if they are not removed in time, they are prone to lead poisoning. Under the level of modern medicine, it is mainly manifested as secondary injuries after the fact, such as surgical injuries. and infections, etc.

Second, lead is soft and will release all kinetic energy after hitting the human body, causing great damage.

Specifically, the warhead is seriously deformed and even ruptured, resulting in a horn-shaped cavity in human tissue, and the wound area is hundreds of times the cross-sectional area of the projectile. is the main instantaneous damage.

3. After the bullet hits the human body, it will instantly exert huge pressure on the human body's blood circulatory system, and then cause great damage. This kind of injury is often overlooked, but it can be very fatal.

After the bullet destroys the blood pressure of the human body, it will cause the person who has been shot to bleed profusely, and the bleeding speed is several times or even more than ten times faster than that of a knife wound of the same area.

It should be noted here that the first shot causes the most pressure on the circulatory system, and the blood splash is the most noticeable. After that, the blood spurt will be reduced because of the lower blood pressure.

Based on this, I will not be wrong in judging the order in which the deceased Choi Young-sook was shot. ”

Chen Geng's introduction was very detailed, and the final summary was very certain.

Jin Yunhao nodded and continued to ask: "I saw you just now, what did you find?" ”

Chen Geng replied: "What I found has nothing to do with the corpse surface examination. ”

Kim Yun-ho insisted: "Then I will listen to it too." ”

Chen Geng hesitated for a moment and said, "Actually, these discoveries shouldn't be told to you, so as not to affect your judgment." But what I've found is something really weird, you see...."

Chen Geng pointed to the dresser behind the dead body and said: "The deceased should have his back against the dresser before his death, and after being shot in the head, his body naturally slipped off, and finally lay on the floor.

I found it strange that the murderer killed with a headshot with a murder gun, and they were all hit in the same place in the head, which shows that the gun pistol is excellent, super good!

But with such good marksmanship, the murderer fired several shots when he shot the second deceased. This is clearly counterintuitive.

This is the first contradiction.

Contradiction two, judging from the situation of the first corpse, the murderer is extremely calm and meets the conditions of an excellent killer. However, when he shot the second person, he fired several shots into the mirror, which is even more unreasonable.

It can be said that when the murderer shot Kong Dongsheng and Choi Young-sook, there was a contradiction between the inconsistencies.

Calm professional and excited amateur situations appear at the same time in a homicide, and this is the strange situation I found. ”

After listening to Chen Geng's introduction, Jin Yunhao nodded slowly.

He was not persuaded by Chen Geng, because he also discovered this abnormal situation at the beginning.

Now it only confirms his own findings and conjectures.

Amateurish, agitated performance, like a sign of an ordinary robbery.

However, judging from the situation of the two deceased being shot, it can be found that the murderer has excellent marksmanship and is extremely calm and shoots at close range.

Two contradictory signs appear at the same time, absolutely abnormal.

All this can be said ...... The case is not as simple as it seems. (To be continued......)
