Ding Xifeng was a little surprised: "So sure?"

"A person's posture is different, the way he walks is also different, and the foothold of the footprints is also different, if the suspect is a hunchback, there will definitely be corresponding footprint characteristics, but this group of shoe prints does not. Han Bin explained.

"No wonder the hunchbacks in the villages around Guojiazhuang have been investigated, and there is no time and motive for committing the crime. Ding Xifeng muttered.

Originally, someone in the team proposed to expand the search area, but now it seems that the target of the investigation is wrong.

"Detachment Ding, how did the suspect kill people?"

"The one who cut with a knife is a ruthless man, and there are blood stains everywhere, and I have rarely seen such a tragic scene after so many years of handling cases. ”

"When the suspect left, was there any blood on his body?"

"According to eyewitnesses, I didn't see it. ”

"I suspect that the suspect was hunchbacked, either deliberately disguised, or he carried his belongings on his back and found blood on his body and wore a coat, which would make him look a little hunchbacked. Han Bin analyzed.

Ding Xifeng nodded, he also thought of this.

"By the way, if you go to the scene of the crime, can you find more clues?" Ding Xifeng asked.

"That's for sure. Han Bin responded.

The footprints in different places, as well as the trajectory of the footprints, also represent different meanings, which need to be combined with the situation on the scene.

Ding Xifeng took two puffs and snuffed out the cigarette butt: "In this way, you clean up and go to Guojiazhuang with me." ”

"Detachment Ding, do you mean to say that let's have our second group also participate in the investigation of the 101 case?"

"The second group is not needed, and the investigation is enough, you can just go with me. ”

"I'll have to report back to our team. ”

"Report it, if he doesn't agree, give me the phone, and I'll tell him personally. Ding Xifeng waved his hand.

Han Bin answered, got up and left the office, and dialed Zeng Ping's mobile phone in the corridor.

"Hey, Team Zeng. ”

"Is the documentary finished?"

"After the filming, I asked Li Hui and them to go back to the bureau, and it is estimated that they should have arrived by now. ”

"Listen to this, you kid didn't come back. ”

"Detachment D left me behind and wanted me to help investigate a case related to footprints. ”

"Detachment Ding came to you directly, what is the case?" Zeng Ping was curious.

"Case 101, have you heard about it?"

"Well, I also just knew, and I said it at a meeting this morning. Zeng Ping responded, and the conversation changed: "Detachment Ding asked you to participate in this case?"

"Yes, Detachment Ding wants me to go to the scene to check the suspect's footprints and see if I can find more clues. ”

"Go ahead, this is your kid's chance, take advantage of it. Zeng Ping said.

"Yes. ”

"Whatever the Ding detachment asks you to do, you can do it, be obedient, there is me here in the second group. After Zeng Ping finished speaking, he hung up the phone.

With Zeng Ping's words, Han Bin also had a bottom in his heart.

......

Guojiazhuang is located near Gaocheng City.

Takashi is one of the managed cities of Kotoshima City, which is a 40-minute drive from Kotoshima City.

Gaocheng City and Yuhua District are at the same level, and once there is a major case that cannot be solved, it will also be reported to the Qindao Municipal Bureau.

At half past twelve o'clock in the afternoon, a police car drove to Guojia Village.

Ding Xifeng and Han Bin got out of the car, and a man in a leather coat walked over quickly.

Han Bin met the other party and immediately recognized it, it was Ma Jingbo, the captain of the second squadron of the Municipal Criminal Investigation Team.

"Detachment D. Ma Jingbo greeted.

"Is there any progress on the case?"

Ma Jingbo shook his head: "A few more hunchbacked men have been investigated from neighboring villages, but all of them have ruled out suspicions. ”

Ding Xifeng pointed to Han Bin on the side: "Let me introduce you, this is Han Bin of the criminal investigation team of the Yuhua Branch." ”

"Captain Ma. Han Bin took the initiative to reach out.

"It's you, boy. Ma Jingbo shook hands with Han Bin and said with a smile: "Ding detachment, I have seen this kid, follow Lao Zheng." ”

"It's better to get to know each other, and it's easier to work together. Ding Xifeng said.

Ma Jingbo guessed: "Do you want to expand the scope of your search by transferring people from the Yuhua Branch?"

"It doesn't mean that. Ding Xifeng waved his hand and continued: "Han Bin is proficient in footprint identification, I asked him to take a look at the footprints found at the scene, and he found new clues. ”

"What new leads?"

"Han Bin, you say it yourself. Ding Xifeng took out a cigarette and smoked it himself.

Han Bin organized the language: "After I looked at the footprints found at the scene, I deduced the general physical characteristics of the suspect. ”

"Tell me about it. ”

"The suspect should be wearing rubber-soled shoes, No. 43, about 1.75 meters tall, about 40 years old, walking with a figure of eight, and no hunchback features. ”

"Not a hunchback?" Ma Jingbo frowned: "Are you sure?"

"Sure. ”

Ma Jingbo touched the stubble of his beard that was a little prickly: "Then the difficulty of investigation is even greater." ”

"Captain Ma, I'd like to go and check it out. Han Bin proposed.

Han Bin was brought by Ding Xifeng, Ding Xifeng's attitude was already very clear, and Ma Jingbo naturally would not refuse: "I'll lead the way, just to tell you about the case in detail." ”

The victim's family of five, the male owner is named Guo Xinfeng, 37 years old this year, opened a small supermarket at the east entrance of the village, because it is a newly built recipe, the area is relatively large, and the things are relatively complete, not only in this village, but also in the neighboring villages, people often go to his house to buy things.

The complexity of the personnel situation also increases the difficulty of the investigation.

Guo Xinfeng has a lady in her sixties, her legs and feet are not very good, and she is a little behind her ears.

The proprietress of the commissary is called Ma Yanhong, 34 years old this year, and her mother's family is from a neighboring village.

Two children, a daughter is eight years old and a son is five years old.

Guo Xinfeng's house has a two-story building in front of his house, a two-story supermarket, and five houses in the backyard, where his family lives.

At this time, Han Xinfeng's family was still holding a cordon, and there were police officers guarding around.

Two days have passed since the incident, and the villagers have lost their enthusiasm for onlookers, but have become a little more afraid of the murder scene, and deliberately walk across the road when passing by.

"The bodies of the four deceased were found in the house, and the hostess was seriously injured and crawled into the yard to call for help, but before she could reach help, the person also died. Ma Jingbo introduced.

"Is there any sign of theft in the supermarket?" asked Han Bin.

"Nope. ”

Ma Jingbo shook his head and explained: "According to Guo Xinfeng's sister, supermarkets used to be stolen often, and then Guo Xinfeng installed surveillance at the front door of the supermarket and inside the supermarket, and every night after closing, Guo Xinfeng would bring cash to the house in the backyard. ”

That is, this person has a certain understanding of the situation in the supermarket, either he has stepped on the point in advance, or an acquaintance has committed a crime. Han Bin guessed.

"That's what we're speculating, too. Ma Jingbo answered and led Han Bin into the courtyard.

As soon as he entered the courtyard, Han Bin couldn't help frowning, and vaguely smelled a smell of blood, of course, it could also be his mental effect.

The yard of Guo Xinfeng's house is not large, and the house is relatively wide.

At the main entrance of the north house, blood stains can be vaguely seen, which were left by the hostess crawling.

Ma Jingbo introduced: "The hostess was stabbed in the neck, chest, and head, and the murderer was very ruthless, and the knives were all fatally wounded. ”

In the middle of the north room is a large living room, the male and female hosts live in the room behind the living room, and the living room can also see the blood stains left by the hostess climbing, and when you enter the back room, a large kang occupies three-quarters of the area, and a human figure pattern is drawn on the kang with white chalk.

"This is the location where the male owner Guo Xinfeng died. Ma Jingbo pointed to the position of his neck: "He was only stabbed once, and he slashed directly on the neck, and his head fell off half." ”

"The murderer is really ruthless. It was the first time Han Bin had seen such a brutal crime scene.

"We analyzed that the male owner Guo Xinfeng was likely to be the first victim, so the murderer was very calm when he killed someone, and when the murderer did it, Guo Xinfeng and his wife probably didn't notice it. Ma Jingbo said.

Han Bin went back to the living room and took a look, the door was just an ordinary aluminum alloy glass sliding door, although it could also be locked, but it was easy to pry open, and there was a thick curtain hanging outside.

"How did the suspect get into the yard?"

"The courtyard gate is an iron door, locked, the suspect can't open it, I guess the suspect should have come in over the wall, there is a wooden board more than ten centimeters wide outside the courtyard wall obliquely inserted into the root of the wall, as long as you run quickly with the help of the slope, you can climb the wall. Ma Jingbo said.

"What about the other victims?"

"In the east house next door. Ma Jingbo sighed, didn't make much introduction, just led Han Bin into the room next to him.

The smell of blood in the East House was even heavier, and Han Bin could be sure that this time it was definitely not a psychological effect.

The east room is separated from a small living room, and then go inside, on the right hand side is a bathroom, on the left hand side is a bedroom, the bedroom is also a big kang, on which a large two, small and three figures are drawn with white chalk, and a large amount of blood is splattered on the wall and the ground, which has turned black.

Seeing Han Bin looking at him, Ma Jingbo was silent for a moment before speaking: "The child and the old man were both hacked to death with knives, and that scene ......"

Ma Jingbo didn't introduce too much, but said in a firm tone: "You must catch this murderer, no matter how difficult it is, you must not let him go unpunished, the two children are really miserable." ”

Ma Jingbo has seen a lot of homicides, to be honest, when he saw the adults who were hacked to death, he didn't have much fluctuation in his heart, he ate this bowl of rice, and he had seen too many similar situations, but when he saw innocent children being hacked to death, he still felt panicked in his heart.

Han Bin didn't speak, he hadn't seen the scene at the time of the crime, he hadn't seen the tragic scene, but he could also imagine how desperate the child would have been at that time.

Knowing the general situation of the case, Han Bin began to study the bloody footprints left by the suspect, although he had already seen the photos of these shoe prints, but looking at the real shoe prints at the scene allowed him to make a more accurate judgment.

Han Bin carefully studied the bloody footprints in the two rooms and the courtyard, and had a more accurate understanding of the suspect's situation.

Han Bin found Ding Xifeng and said straight to the point: "Detachment Ding, have you made any progress in the search of the suspect?"

"Although it is very possible for acquaintances to commit crimes, considering that Guo Xinfeng opened a supermarket and there are more people coming and going, it is very difficult to investigate. Ding Xifeng shook his head and glanced at Han Bin again:

"How's your research going?"

"My judgment of the suspect is still the same as before, about 1.75 meters tall and around 40 years old. Han Bin said.

"Brother Han, people from these nearby villages will come to the supermarket to buy things, this range is still too large, and there are other characteristics that can distinguish the suspect. Ma Jingbo asked.

"Yes, but only I can tell. ”

"What do you mean?"

"Detachment Ding, Captain Ma, if you two believe me, you can gather the men in the surrounding villages who match the characteristics of the suspect, maybe I can find which one is the suspect. Han Bin said.

Ma Jingbo frowned: "I estimate that there are at least a few hundred people who meet the characteristics of height and age." ”

"I know. ”

"How sure are you?" asked Ding Xifeng.

"Eighty percent. ”

"How exactly?" Ding Xifeng has no better direction to investigate now, and can only choose to believe Han Bin.

The suspect did not leave fingerprints, there was no surveillance around the village, and witnesses only saw the general figure of the suspect, and it was difficult to find the suspect with the existing clues.

"Find an open place, gather the eligible men in the neighborhood, and walk in front of me alone. Han Bin said.

"And then?" Ma Jingbo asked.

Han Bin spread his hands: "If it's a suspect, I can naturally tell it." ”

Ma Jingbo was a little unconvinced: "This is too child's play." ”

"Don't you need to collect their shoe prints?" Ding Xifeng was also a little surprised.

"It takes too long to collect shoe prints one by one, so I will pick out some key suspects and collect their shoe prints for comparison. Han Bin explained.

Ding Xifeng thought for a moment, and said to Ma Jingbo on the side: "Okay, just do what Han Bin said." ”

"Boss, this is not a playhouse, this ......" Ma Jingbo was a little depressed, isn't this a blind toss, let other colleagues in the team hear it, and they can't laugh off their big teeth.

Ding Xifeng glared: "Do you have a better direction to investigate?"

Ma Jingbo suddenly wilted, and glanced at Han Bin again: "Boy, if you really want to catch the suspect, you kid is the first talent, if you can't catch it, be careful when you go out at night." ”

Han Bin couldn't laugh or cry, what is this called.

After seeing Ma Jingbo leave, Han Bin couldn't help but ask: "Detachment Ding, if you really can't catch someone, Captain Ma won't really beat me, right?" ”

Ding Xifeng smiled: "I can't guarantee this." ”

Han Bin "......"

Guojiazhuang Village Committee Compound.

In addition to the fields, this is the most spacious place in Guojiazhuang.

There is a basketball court on the east side of the courtyard and two table tennis tables on the west side.

Ding Xifeng and Han Bin sat on the basketball court one by one, still holding a teacup in their hands, it was too cold.

Ma Jingbo commanded on the side: "Hurry up, hurry up, stand in a row, walk one by one, from the south end of the basketball court, to the north end of the basketball court, and then, sign your name in the notebook, and you can leave." ”

"Got it. ”

"Understood. The villagers responded with a mouthful of tongues.

Ma Jingbo is in charge, and the village cadres and members of the municipal criminal investigation team are responsible for maintaining order.

Five minutes later, according to Han Bin's previous instructions, male villagers between the ages of 173 and 177 and between 38 and 42 began to model in the village committee compound.

It was the first time for a group of big men to encounter this kind of thing, and they let out a burst of laughter from time to time, and occasionally glanced at the police officer next to them, as if to say, this group of people is not stupid, if the suspect can be caught, Lao Tzu can be a policeman.

"Fellow countrymen, be quiet, don't be chaotic, let's finish early and go home early. The surrounding interpol team members shouted.

These members of the criminal police team are the elite of the city's criminal investigation team, and it is the first time for them to do this kind of inscrutable work, not to mention how depressed they are.

Han Bin was not affected by the outside world, sitting in the middle of the basketball court, watching everyone who passed in front of him, observing their body shape, walking posture, gait, the weight of their feet, and so on.

Han Bin looked at it very carefully, and if he couldn't get it, he would let people go through it again.

Ding Xifeng looked at it for a while, feeling a little boring, he really couldn't see how different this person could be from walking.

A group of big men, not even small fresh meat, what's so good-looking.

If you want to gather all the eligible villagers at once, it is impossible, you can only come in waves.

There were probably dozens of people in the first wave, and except for a few who walked twice, there was basically nothing abnormal.

Then came the second wave, still dozens of people, one by one on the basketball court.

When many women heard the news, they also ran over to see the excitement, especially some married women, who spoke meat more than men, and pointed to a group of old men to judge their tastes.

In this wave of people, Han Bin picked out a man, 39 years old, from Guozhuang Village, named Tong Dabao, an old bachelor, and he was a foreign figure when he walked.

The third wave is the villagers of the neighboring village Fucheng Village, Han Bin picked out another man, named Li Jiaba, 40 years old, Fucheng Village is just east of Guojiazhuang, very close to Guo Xinfeng's supermarket, even closer than many villagers in this village.

Two more groups of people came one after another, it was already dark, and another homicide had just occurred, and the villagers were reluctant to go out, and the investigation could only be temporarily concluded.

Han Bin found a total of five suspicious objects, and asked the technical team to collect the shoe prints of the five people and compare them.

The five people who were more suspicious were also temporarily invited to the village committee to rest, and there were special police officers to take care of them, and the village committee had heating, tea, and dinner.

In fact, after reading it, Han Bin already had a rough idea in his heart, although he chose five suspects, but one of them was the most suspicious.

Soon, the technical team collected the shoe prints of the five people and sent them to Ding Xifeng, Han Bin, and Ma Jingbo.

Ding Xifeng handed it directly to Han Bin: "It's up to you." ”

Ma Jingbo also patted Han Bin's shoulder: "Everyone is counting on you." ”

The people from the other city's criminal investigation teams also looked at Han Bin, expectant, suspicious, and more curious.

Han Bin suddenly felt Alexander.

If this Nima misses, he will have to weigh it when he goes to the city bureau in the future.
