Chapter 1154: A Heavy Stroke in Criminal Investigation History

"These are the photos of the scene, take a look." Wang Xin took out two small paper bags and placed them in front of Wang Yan, "This is the first time we found the remains on the train, the body found at the end. This is the second body, the two crimes were two months apart. This photo is of that Ding Gui'an, look, he has a character 'Yi' on his arm, the same as the one on the second body's arm.

And this person is the same as Ding Gui'an, both are type B blood. So comprehensively, we temporarily determined that this person is Ding Gui'an. Another thing is this gesture, with the little finger raised alone, I haven't figured out what it means."

Wang Xin sighed and said, "This case, logically speaking, shouldn't be ours. It's Harbin's, the arm came from Harbin, and the victim is also Harbin's. But they didn't take it, and we found it, so it fell on us."

Wang Yan flipped through the photos and said with a smile: "What, unhappy to have a case? Besides, the information is so complete, they also tried their best, they must be investigating it themselves."

"We don't lack cases to do, this is still headless and tailless, random murder, and there's no clue so far. What do you see?"

"This murderer has become addicted to killing, he is intentionally killing to find stimulation."

"How do you see that?"

"Regardless of what this gesture means, two consecutive bodies appeared with this, and the two had no connection at all, which is what you just called random crime. Then in this case, there is only this one explanation. The file records that the victim's property was lost, indicating he is seeking money.

The cause of death for the first body was a heavy blow to the back of the head, and the murderer's method of dismembering the body was also extremely rough, and he changed tools in the middle. First a knife, then an axe, and finally a saw, the knife and axe marks were messy first and then neat, indicating that his method was unfamiliar at first, his heart was flustered, and he acted hastily, but later he gradually became addicted to it, and his mentality stabilized.

By the second body, one knife to the throat, crisp and direct, this is aimed at killing, of course, the money on the victim was also scraped clean. The gesture on the two arms connects the first and second bodies, after all, such a coincidence almost doesn't exist. Thus, it is determined that it is the same person committing the crime, and the method of committing the crime is upgrading.

The first time he failed to rob and killed, the second time he killed to rob. Unsurprisingly, there will be a third crime before long."

Ma Kui nodded: "We also judged it this way, but not as detailed as you said. Then what do you think this gesture means?"

"It's just a normal meaning."

"What does normal mean?"

"Don't think so complicated."

Wang Yan didn't doubt that Wang Xin was pretending to be stupid, thinking too much, so he couldn't think of simple things.

He compared his thumb: "This, is awesome, is the best."

He retracted his thumb again and extended his little finger, "Then what do you think this can mean?"

"I fuck his mother, is he provoking us?" Wang Xin reacted immediately.

Wang Yan nodded with a smile: "That's exactly what it means, he got a feeling from killing, and his spirit is not normal either. As long as he can't be caught, he will keep killing and keep provoking. Of course, it doesn't exclude that his brain cleared up during the process, had some other thoughts, wanted to live a stable life, and put down the butcher knife."

"Fuck, he even became a Buddha." Wang Xin was even angrier, he didn't lack a sense of justice. Not to mention being provoked like this now, and still not being able to catch the person, this feeling is not very good.

Watching Wang Yan flip through the file again, Ma Kui asked: "What, do you have ideas?"

"I looked at the situation of the second body, as well as the photos of the crime scene, and the information of this Ding Gui'an. My judgment is that the dead one is not Ding Gui'an, the one who did it is."

"What?" Ma Kui froze for a moment, "Are you sure? How do you see it?"

"I judged by looking at the photos of the deceased, his age should be about thirty, Ding Gui'an is twenty-six. The range given by the forensic doctor over there is too large, so it covered Ding Gui'an's age. Coupled with similar height and weight, it led to a wrong judgment. This has information about Ding Gui'an before being processed, at that time he was twenty-five, height 176, weight 63 kilograms. It is similar to the data of this footprint, just the weight is lighter."

Wang Yan displayed the photos and the text on the file while speaking, "So I boldly guess that the murderer is Ding Gui'an. He was afraid that it would be found on his head, and just happened to encounter this person of similar height and weight, tattooed the same character on his hand, and smashed the person's face, intending to confuse the public and blind us, while Ding Gui'an faked his death to escape, making us think he was already dead."

Ma Kui nodded: "Your statement is established, and it can also match."

"It's useless even if it matches? If you can't catch the person, isn't it all in vain? According to what you said, Ding Gui'an has already escaped, changed his name and surname, and is completely committing random crimes, where are we going to find him?" Wang Xin scratched his head, smoking the Huazi Wang Yan threw on the table.

Ma Kui let out a long breath and shook his head helplessly: "Can only wait for him to commit a crime again. Both crimes were around Harbin, maybe the next time will still be there. At that time, we will go over immediately. See if you can find the person along the footprints."

"Not likely, he has changed his name and surname, next time he will definitely commit a crime in another place, otherwise wouldn't that attract our attention? This Ding Gui'an is not afraid of anything now, just afraid that we are squatting in Harbin, knowing he is Ding Gui'an."

Old Ma of course also understood this truth, it's just that he said it for the better. Glancing at Wang Xin, he didn't refute.

"Another progress, thinking quite comprehensively." Wang Yan gave Wang Xin an affirmative look, "It's been more than two months since the last crime, I guess this Ding Gui'an should be itching, he will definitely commit a crime within these one or two months. Let's do this, you contact various places, tell them about this case, and mention the characteristic of the little finger. Let them try their best to preserve the scene, and we will go over to see it then.

If the scene is well preserved, maybe looking at the footprints, we can find the person. He provokes the police like this, according to common sense, he will definitely not leave immediately after committing the crime, he has to watch us running around like headless flies, and only then will he feel happy."

"It still has to be you, even dogs aren't as powerful as you, what are we training police dogs for. Hey, speaking of this, I remember. That old blind man's nose is so powerful, isn't it a waste of talent in the nursing home? Why don't we bring him to the train station, he can definitely smell the drugs, we give him a salary, and he has a sense of achievement. How good is that."

"Get lost." Ma Kui glared and scolded, "Why don't you lead yourself over."

"Give me back my cigarette, don't smoke my cigarette." Wang Yan also beckoned.

"Look at you, I'm just joking. Doesn't this show that you and the old blind man are both powerful, what, can't be more powerful than police dogs? The treatment of police dogs is so good."

"I think you're just itching for a beating, get lost to the side, hurry up and call to contact for assistance."

So everyone got busy, Wang Yan flipped through the file again to see if there were any cases that could be solved.

Actually, if you ignore the pain of the victims, ignore the reasons for various murders, then the process of solving the case actually feels very good. Compared to constantly repeating in the criminal science center, as far as Wang Yan's preferences are concerned, he actually prefers to solve cases on the front line...

Two days passed like this, on an ordinary morning, the bureau leader came in person to hold a meeting for the criminal investigation brigade, praised Comrade Wang Yan's spirit of constantly learning and applying technology to solve cases, as well as the merit of solving hundreds of cases, and called on comrades to learn from him, and publicly announced the appointment of Comrade Wang Yan as the deputy brigade leader of the Ningyang Railway Public Security Criminal Investigation Brigade, assisting Comrade Hu Guangjun in leading the work of the criminal investigation brigade, fulfilling the responsibilities of the people's police, and ensuring the safety of people's lives and property.

Regarding this matter, the comrades of the criminal investigation brigade were not surprised, they of course all knew that Wang Yan was awesome to the sky, just didn't expect that Wang Yan was not transferred, but still here. As for being their leader, no one had any opinion. The record made them feel ashamed, and his way of dealing with people also made them unable to pick any faults, quite good.

It was just Wang Xin who was envious, jealous, and hateful, he knew everything, but the two grew up together, he watched Wang Yan grow from small awesome to now, the gap was getting bigger and bigger, while blessing, he felt more that goods compared to goods should be thrown away, people compared to people should die, of course, it was not very comfortable.

After the promotion, Wang Yan didn't have any place to lead. After all, for the superiors, what they look at is whether he can fulfill his duties and ensure the case clearance rate. For the subordinates, what they look at is whether he is fair enough in rewards and punishments. But the awkward thing is, he is the second in command, and he doesn't need to reward or punish.

So although he is the deputy brigade leader, there is no change. It's just that he provides some technical support, and each team solves cases by themselves. He still takes Ma Kui and Wang Xin, and still does cases. The difference is that now current cases appear, and in cases where the impact is not great, he is the leader of the case, and he also bears the responsibility.

Wang Yan didn't take Old Hu's power, it wasn't worth it. Old Hu's requirements were not high, it was best to go up two steps before retirement. He couldn't solve cases, but he was willing to do a good job in logistics, just counting on Wang Yan to make merits to push him up.

Wang Yan didn't like to do these things either, after all, if he really wanted to be a leader, this level had no challenge, and the challenging ones were dangerous, so it was better to solve cases steadily and be a technical talent.

At the same time, his hanging position in the Criminal Technology Department of the Provincial Department was also handled, and this side was quite generous, directly arranging a deputy director position for him. After all, a bunch of people here combined were not as awesome as him alone. Just as mentioned earlier, he was responsible for technical training and technical support.

Not only that, he also served as a lecturer at the Criminal Police Academy located in Ningyang. This was a professional criminal investigation institution expanded from the People's Police Cadre School of the Ministry of Public Security in 1981, and it would also be the cradle of the police world in the future.

However, he was not a full-time lecturer, teaching four classes a month, one class a week. If he had something to do, he would notify in advance and arrange the class time. He taught criminal investigation technology, but it was not limited to criminal investigation technology, after all, he knew quite a lot. He discussed with the department leaders, one class for an afternoon, directly taking cases to talk about things, from beginning to end. One class taught one case, and professional technical knowledge was infiltrated into it.

Although normal classes also required these, lecturers would also unconsciously take cases to talk about things, and tell some interesting cases they knew to liven up the classroom. But relatively speaking, what he taught was more comprehensive, after all, he was specifically talking about cases, from beginning to end.

There were many things involved, from investigation, to various means of solving cases, to interrogation, and case closing, which was the all-around application of criminal investigation technology.

So he started writing books again, professional knowledge in fingerprint comparison, footprint identification, forensic identification, trace identification, criminal psychology, bloodstain analysis, etc.

He actually had weaknesses, such as document inspection, trace evidence, poison inspection, etc., he was not professional in these things, the reason was that his past experiences involved relatively few, and he didn't specifically study them.

These things he knew, except for fingerprints which he specifically learned, the others were all experiences. He specifically studied the human body, and was also a dual cultivator of medicine and martial arts, so he was familiar with the human body, so forensic identification was awesome, and footprints were clear in his chest. He was familiar with killing, mastered various postures of killing, understood the effects of various tools, so bloodstain analysis was awesome. He was familiar with murderers and hooligans, had an understanding of people, so criminal psychology was professional.

Other trace identification, etc., mainly lay in his keen observation. Just like catching that thief stealing track parts before, that was his meticulous observation, able to distinguish.

Greed is not good for chewing, although this principle didn't apply to him, he definitely wouldn't learn useless knowledge, this was certain, it was really unnecessary. But even so, the things he mastered were quite amazing.

These books were written, and he was destined to leave a heavy stroke in the history of Chinese criminal investigation. Twenty years later, when his peaches and plums were all over the world, it would be the time for him to become a master in the criminal investigation world.

Besides these, his three positions added up, and his monthly salary went directly to two hundred yuan. However, he didn't care much about the salary, after all, he didn't lack money...

Like this, his life stabilized. Except for every Friday, training high-level professional technical personnel in the Criminal Technology Department in the morning, and giving a big class at the Police Academy in the afternoon, Wang Yan solved cases during the day, wrote books at home at night, and occasionally went undercover to take trains on various lines, catching thieves and human traffickers on the train, and dealing with some emergencies.

This life lasted for nearly two months, and on this day, just after starting work, Wang Xin received a call.

Then he looked at Wang Yan and Old Ma, and said: "Ding Gui'an has movement, this bastard really ran away, last night in a county town under Chunlin, he killed a woman. The key is that it rained heavily over there last night, the footprints must be clear, this is good news, right?"

"People coming and going, who knows what it will be like after we go over." Wang Yan shook his head, "Hurry up and tidy up, three hundred kilometers, we drive over, faster than the train."

No more nonsense, told Old Hu, Ma Kui called home, and the trio drove directly to Chunlin...

"Brother, you have to keep up that awesome energy, whether we can catch the person depends on you. If we let this bastard keep killing, how many people will be killed before it ends."

"If possible, I hope that as soon as I exert my magic power, all murderers will be detained in front of me, lining up to wait for shooting."

"If only there was such ability."

"Since there isn't, what are you farting for? Drive your car."

"Look at you... oh my, why do I feel a bit sleepy, no energy at all, want to smoke a cigarette..." ===== CHAPTER 1155 =====
