37 shoe size, many children wear 37 shoes at the age of 11, this foot is a bit small!

But this footprint is the clearest footprint on the scene, in fact, it is not a footprint, but a group of footprints. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The info technical police were puzzled, Han Bo also felt a little strange, and looked at a few marks made on the surface of the house, confirming where to put his feet would not destroy the scene, and walked in to investigate together.

Footprint gait analysis is a practical technique with strong theoretical and practical aspects, and it is necessary to clarify the ground conditions left by footprints according to the site conditions. For example, the softness and hardness of the ground and the influence of various actions on the characteristics of footwork are analyzed, and various factors of the footprints left behind at the site are analyzed, and a comprehensive judgment is made.

On the premise of determining the conditions of the footprints, the gender, age, height, posture, walking posture and so on of the footprints were analyzed.

Han Bo squatted down, touched the dust on the ground, and then moved forward, observing the characteristics of the footprints with the technical police.

In general, people who are short but have big feet are prone to pedal marks, step marks, and buckle marks. Tall people with small feet generally have their thumbs down, the outer edge of the forefoot is small, and the outer foot is large......

After carefully observing and studying for nearly half an hour, his legs were numb.

Han Bo stood up, walked out of the house, took out his mobile phone, and used the calculator in his mobile phone to convert it using the formula.

During my study at BJ, I visited a footprint expert and humbly consulted the footprint gait analysis technique, which I had never used over the years, but I didn't expect to use it today, but the clues from the footprint analysis can only be used as a reference.

If he hadn't inquired before, Miao Wentao would have directly thought that he didn't know how to pretend to understand.

But now is not the past, Du Zhigang said that the person in front of him is the director of the Criminal Technology Center of the Nangang Public Security Bureau and the director of the Criminal Science Research Institute.

Miao Wentao came over and asked curiously: "Han Chu, can you analyze your height and weight?"

"It's really a bit strange, if nothing else, the person who left this group of footprints is a man, around 16 years old, about 1.61 meters tall, weighing about 48 kilograms, with a thin body and small legs. ”

"Kids?"

"Could it have been before or after the crime?"

finally made some progress, but such a situation emerged, Miao Wentao and Lao Yu couldn't cry or laugh.

Han Bo looked behind him, and while leading the two of them towards the east gate, he said with a bitter face: "Judging from the scene, several footprints were left at the same time. ”

"Is it possible that the height and weight are consistent, and there is an error in age, after all, people are different, especially in development, you see those dwarfs, dozens of years old are still so tall. ”

"Possibly, so footprint gait analysis can only be used as a reference. However, judging from the texture of the shoe print, it should be a pair of sneakers, the kind of sneakers that students like to wear. ”

"What about the other footprints?"

"They are all men, they should not be very old, their stature should not be tall, and their weight should not be heavy. ”

"A group of children killed people?" Miao Wentao felt incredible, thought about it and said: "It should have been after the crime, there were many children in this place who came to play, and the footprints were left by them, not the traces of the fight." ”

The traces of the fight and the footwork echo each other, thinking of the 110 police cars encountered on the way, and thinking of a group of lawless minors fighting, Han Bo sighed: "Team Miao, Section Chief Yu, I think you are not mistaken, this case should be done by a few bear children." ”

"What about the motive, fun?" Lao Yu really didn't dare to imagine, and couldn't help frowning slightly.

"It's fun, it's exciting, it's a gauntlet, and maybe even a ritual to admit new members into their little gang. In TV and movies, they are killing chickens, they are killing people, not only killing people, but also blaming others. ”

"Whether it is or not, it should not be verified. Miao Wentao had a preconceived idea just now, thinking that only adults can do murder, and now the more he thinks about it, the more reasonable it becomes, because there is only this one possibility after excluding other possibilities, not to mention that there are footprints at the first scene.

"I called the Ying detachment, Wang Yunhai should not have let go, ask the four wronged leaders, if it is true, they should have an impression. ”

……

When he received the call, Ying Chengwen did not dare to delay for a moment, and immediately notified the police who were being interrogated in the No. 1 Detention Center for verification, and he walked into an office on the second floor of the Third Criminal Police Brigade to personally question Wang Yunhai.

"No, Comrade Public Security, I really don't! I know the severity, I just earn a little money to support my family, how can I rent those plates to children?"

Until now, Wang Yunhai did not know the real purpose of the Cultural Affairs Bureau and the Public Security Bureau jointly enforcing the law and bringing him here. In his mind, the police only know how to pay money for fines, and how dare they admit to renting pornographic CDs to minors?

His eyes flickered, and he knew he was lying at a glance.

Don't tell the truth, Ying Chengwen's lungs were about to explode, he opened the briefcase, and snapped a stack of photos in front of him, "Wang Yunhai, you don't tell you honestly when you die, do you want to live anymore!"

"Comrade Public Security, don't scare me, isn't it just renting a DVD, what's the matter? I'm a laid-off worker, I'm fending for myself, and I'm not causing trouble to the government, so don't trouble me, okay?"

"Look clearly, take a closer look!"

I don't know if I was framed and blamed, if I hadn't been negligent at the time, and I found you through the tie, and you couldn't come up with an alibi, you might really be a substitute for the dead.

Ying Chengwen glared at him fiercely and held up a photo: "Whose tie is this, it's not familiar, how could it appear at the scene of the murder?"

"Murder, this ...... It's none of my business. Wang Yunhai was stunned.

"It's none of your business, look at this, do you know this person, he and pee in front of your store, you beat him, the whole world knows it. ”

Ying Chengwen pointed to his nose, picked up the small camera, flipped out the video recorded during the noon search, and fast-forwarded to the part where the fruit knife was found: "See, the murder weapon was also found in your store, you said it was none of your business, who would believe it?"

It turned out to be the matter of the old beggar and the old bastard, Wang Yunhai reacted, crying and mourning: "Comrade Public Security, I was wronged, I beat him, if he shit and pee at the door of your house, you are not angry, but...... But I really didn't kill him, how could I kill someone, how could I kill someone for this little thing!"

"You didn't kill it, then you tell me how the tie was at the scene of the crime, and how could the murder weapon be in your store?"

"I'm wronged, I'm sure which king-eight-egg planted the blame. ”

"Who will blame you, why blame you, why doesn't he blame others?"

"Think about it, Ding Erdan, it must have been Ding Erdan's doing, he didn't think about my wife for a day or two, and everyone in the neighborhood knew it. ”

"Ding Erdan?"

"The nickname is Erdan, and I don't know the big name, but ...... But it's unlikely to be him, he went to Dongguang to work last year and didn't come back during the Spring Festival. It could also be him, secretly running back to kill people, and then blaming me and framing me. ”

It turned out that the public security went to raid the store because of this, Wang Yunhai finally reacted, didn't dare to joke with his own life, and said more than a dozen people who might be guilty of blaming the blame, but he didn't expect that he really had a lot of enemies.

It is unlikely that he killed people because of the homeless man pooping and peeing in front of the store, and it is also unlikely that the dozen or so people he said killed people by killing people because of those things.

Despite this, the names should be written down one by one.

When he couldn't think of anyone with contradictions, he asked coldly: "Wang Yunhai, please clarify your situation, the last question must be answered truthfully." ”

"Comrade Public Security, if you ask, I promise not to tell lies. ”

"Did you rent the DVD to a minor?"

"Rented. "Life hangs by a thread, Wang Yunhai doesn't dare to say anything more.

"How much?"

"Not much, not too much. ”

"How many?"

Wang Yunhai thought about it and said honestly: "There are more than a dozen people who often go to my place to rent properties. ”

"What are their names, what do they look like, what are their approximate ages, what school do you attend, do you have any impressions?"

……

I didn't know, I was shocked when I asked, one of them went to rent a yellow-colored CD, and because he spent the disc and had a dispute with Wang Yunhai, the age, height, body type, and gait almost completely matched the characteristics provided by Han Bo.

Binggui was so fast that Ying Chengwen didn't have time to interrogate him again, so he immediately took him to the No. 4 Middle School for identification.

Han Bo received the report and hurriedly reminded: "Ying detachment, all kinds of indications indicate that several cases are very likely to be committed by multiple people, and it is very likely that minors, I don't think we can startle the snake." First, ask the school for a photo of the student, let Wang Yunhai look at the photo identification, and then find out the student's situation during the school period after identification.

Find out who you usually hang out with and where you often go to play, and then take other people's photos for the three people detained in the detention center to identify, confirm that they are correct, and then take action, not only to take coercive measures, but also to collect and fix evidence at the first time. ”

was almost made out of a series of unjust cases by a group of stinky boys, as the leader of the criminal investigation detachment, Ying Chengwen's mood can be imagined.

I didn't control my emotions just now, I just wanted to catch the real murderer as soon as possible, and I almost made a mistake again.

He quickly calmed himself down, clutched his mobile phone and said, "Don't worry, Han Chu, I won't act rashly, it's already like this, and I can't fight a battle that I'm not sure of." ”

"Okay, you take Wang Yunhai to No. 4 Middle School first, and I'll go to the detention center to wait for news with Song Ju. ”

It only takes one opportunity to solve the case, and it turns out that Miao Wentao's discovery is extremely valuable, according to the first scene he discovered, according to the clues analyzed through the footprints left at the first scene, Ying Chengwen quickly locked up seven suspects, got seven photos, and at 5:21 pm, the three "suspects" detained in the first detention center of the Dongping City Public Security Bureau identified four of them!
