Previously, the content of the new case in the previous chapter was overwhelmed.

You can’t write a case, you can only modify the outline and think about a case again.

The end of the previous chapter has been revised, so you can revisit it.

...

At 10:30 in the morning, Han Bin rushed to the Jiufujin Store on Dingxi Road, with only Zhao Ming and Zhang Shungu by his side, and the others were still on vacation.

Han Bin has notified Wang Xiao and Zhu Jiaxu, asking them to assemble their team members to the scene of the crime as soon as possible, and the vacation can only be cancelled temporarily.

The 403 gold shop robbery was committed at 9 o’clock last night. Because the light was dark at that time, the site survey would have a certain impact. It is very likely that the site will be surveyed again the next day. In order to avoid damage to the scene, the police have always sent people to protect the scene. .

A cordon was pulled at the door of the store, and two police officers from the police station stood at the door.

Han Bin showed his police officer ID, and the policeman on guard hurriedly saluted.

Han Bin did not rush into the store, but looked around. This store is located in the downtown area of ​​Qindao. It is a relatively prosperous place in Chengbei District. There are many cameras installed around it. Dingxi Road is less than one kilometer away. Police station.

Han Bin regained his gaze. Surveillance cameras are also installed at the entrance of the gold store. It seems that the equipment should still be usable. It has to be said that these gangsters who rob the gold store are really bold.

Han Bin crossed the cordon and walked into the gold shop. The gold shop covers an area of ​​about 70 or 80 square meters with rows of glass counters. The counter has been damaged, there are a lot of broken glass scattered on the ground, and the gold and silver jewelry inside the counter has been swept away.

There were some sporadic blood stains scattered on the counter and on the ground, which looked a little scary and was also important evidence.

Judging from the situation described by Ding Xifeng, these bloodstains were probably left by the injured clerk. But there is no absolute truth. When the suspect hits the counter, he may also be scratched by the glass on the counter. The large amount of scattered blood may also be mixed with his blood.

If bloodstains of the suspect are found, breakthrough progress will be made in the detection of the case.

Generally speaking, the robbery scene of this gold shop is not much different from most gold shop robberies.

Four monitors are also installed inside the gold store. Three monitors face the glass counter, and one monitor faces the cash register. As long as these monitors are not damaged when the robbery occurs, the surveillance video can be used to perfectly restore the incident.

This is crucial to the detection of the case.

While Han Bin was checking the scene, members of the Second Squadron arrived one after another. These members were all elites in the criminal investigation system of Qindao City, and soon moved from vacation to work.

"Woo..."

At this moment, a black car parked near the Jindian, and Ma Jingbo got out of the car.

He Yingsheng's eyes were quick and quick, and he reminded, "The horse team is here."

Han Bin also walked out of the gold store and greeted, "The horse team."

Ma Jingbo patted Han Bin's arm, glanced at the people in the second squadron, and smiled, "Everyone is here."

"cavalry."

"Good horse team."

"The horse team, I heard that you have been promoted to the captain of the Criminal Investigation Brigade of the Chengbei Branch, so why don't you invite us to dinner."

Ma Jingbo smiled, "It hasn't been a long time since I took office, and my work hasn't been smooth. There is no time to invite you to dinner. When this case is over, I will treat you to a big meal. You can't miss one."

"Great."

"The horse team treats, how dare we not go." The team members roared.

Han Bin said, "The horse team, why did you come in person? I also said that after checking the scene, I will go to the North Branch to see you."

"I missed you. I haven't been on a mission with you for a long time. I just missed this opportunity." Ma Jingbo waved his hand, "Go, I will introduce you to the scene."

"The time of the crime was nine o'clock last night. The two suspects rode their motorcycles to the gate of the Jindian and parked their motorcycles at the gate. The two went directly into the Jindian. The two suspects had guns in their hands, and they were quickly under control. The staff of the gold store was closed, and the roller shutter of the store door was closed immediately.

One of the clerk wanted to escape under the chaos. He was holding a suspect and injured his head with a hammer. Then the rolling shutter was pulled down. The gun suspect controlled the clerk, and the other suspect was responsible for smashing the counter and robbing him. Go gold jewelry.

The entire crime took a very short time. The time from pulling down the rolling gate to pulling up the rolling gate was less than four minutes. After that, the two suspects left the gold shop on their motorcycles. Only then did the clerk have time to call the police and wait for the police station comrades to arrive. At that time, the suspect was gone. "

Han Bin asked, "When the suspect pulled down the rolling shutters, no one doubted it. The neighbors didn't help the police?"

"It was already nine o'clock in the evening, and there were not many pedestrians around, and some shops were closed. Even if the shops were not closed, the clerk would not stand at the door and stare. The suspect did not attract attention when he entered the gold shop. Afterwards, we also visited a 24-hour convenience store.

At the time of the crime, there were two employees in the convenience store, but the two employees were shifting shifts. At that time, they did not see the suspect enter the gold store. However, they said that they heard a shout during the time of the crime, and it was probably the injured person. Sent by the clerk.

One of the clerk of the convenience store also stood at the door to check, but there was nothing unusual on the street at the time. The Jindian had already lowered the rolling shutters. They thought it was going to close, so they didn't think much about it and returned to the store. "

Han Bin said, "There are only two suspects? Is there no lookout outside the shop?"

"From the existing monitoring and clues, the third suspect has not been found yet."

"What about the blood on the scene?"

"It should be all the bloodstains of the clerk. No blood samples of the second person have been found."

Because the people from the Criminal Investigation Brigade of Chengbei Branch had already surveyed the scene, Han Bin led people to survey the scene again, and it was much simpler. He only understood the situation on the spot and had a definite impression in his mind.

Afterwards, Han Bin and others followed Ma Jingbo back to the North Branch.

In the meeting room of Chengbei Sub-bureau, Han Bin met Hao Jianbo and Zhao Renqi again, because everyone had drunk together, got a lot of familiarity, and was also convenient for cooperation.

Afterwards, Han Bin checked the surveillance at the time of the incident. The video content was very clear. The two suspects rode a red motorcycle and parked at the gate of the Jindian, wearing helmets and entered the Jindian, and then switched to the surveillance inside the Jindian.

In terms of body size, the suspect should be two men, one of them is wearing a black jacket and dark blue pants, the other is wearing a fur collar coat and black pants, the man riding a motorcycle wears black leather gloves, and the other is wearing black leather gloves. The man put on transparent plastic gloves after entering the store.

From this point of view, the suspect has done his homework beforehand. The risk of robbery in the downtown area is high and the action must be quick. The most time-consuming part of robbing a gold shop is to collect the gold and silver jewelry in the gold shop. The more inconvenient it is to collect the gloves, the lighter and thinner plastic gloves will not leave fingerprints, which is the most suitable.

The two men were carrying bags on their bodies. After entering the store, the man riding a motorcycle took out an earthen pistol from the bag, and the other man pulled down the rolling shutter. It was at this stall, leaning against the door. The nearby clerk tried to escape from behind the two suspects.

It's a pity that this action was seen by the suspect who pulled the gate. He took out the hammer from his carrying bag and slammed it on the head of the escaping clerk without hesitation.

"Bang!" During the whole life, blood was splashed, and the clerk screamed and fell to the ground.

The man armed with a gun rushed over to help, kicked the injured clerk, and the other suspect continued to pull down the rolling gate.

The rolling gate fell, and the two suspects worked in a division of labor. The man armed with a gun was responsible for guarding. Another man smashed the glass counter with a hammer to quickly collect the gold and silver jewelry in the shop.

"Bang bang bang!" The sound of smashing the glass was endless.

Several shop assistants were so scared that they hid on the sidelines. With lessons learned, let alone calling for help, they didn't dare to make a sound.

After taking away the gold and silver jewelry, the two suspects left the gold shop, and the screen again turned to the surveillance outside the shop.

The two suspects rode on their motorcycles and quickly disappeared under surveillance...

After reading it, Han Bin had three words left in his mind: clean, neat, and brutal...

Hello everyone, our public account will find gold and coin red envelopes every day, and you can receive them as long as you pay attention. Please seize the opportunity for the last benefit at the end of the year. Public Account [Book Friends Base Camp]

After Han Bin watched the video, Ma Jingbo on the side asked, "How is it? What did you find?"

Han Bin pondered for a moment, "The sound of breaking glass is so loud, and the convenience store is only more than 20 meters away. It stands to reason that it is impossible for the clerk to hear it."

Ma Jingbo said, "Yes, there is a problem with this point. I will write a note for them later. If these two people really conceal it, we must find out the reason.

The Korean team, are there any other discoveries? "

Han Bin continued, “According to my observations, the man with a gun should have been injured in his leg. The age should be around 45. The man with a hammer is relatively young and should be no more than 30 years old. Of course this is only through According to a rough observation of the video, if the technical department can collect the traces of the suspect, it can be more accurate."

Ma Jingbo spread his hands, "Unfortunately, no traces of the suspect were found at the scene."

Zhao Renqi was a little surprised, "Captain Han, I have heard of the technique of judging height based on the video. This suspect hasn't even shown his face. Can you judge their age?"

Han Bin said, "I have learned some techniques of footprint identification, and can roughly judge the age of the suspect based on the suspect's walking posture, gait, and characteristics."

The people in the second squadron looked like they were taken for granted, while the people in the north branch were somewhat skeptical. Although they all knew about the identification of footprints, they knew that this knowledge was very complicated, and it was hard to believe that they hadn't seen it with their own eyes.

Ma Jingbo smiled and didn't give too much explanation. It was a mule or a horse. When the suspect was caught, he would know it naturally.

Han Bin said, "The horse team, I heard from Ding Detachment that there were two gold shop robberies seven years ago. I don't know what those two cases have in common with this one."

Ma Jingbo took out two kraft paper bags and handed them to Han Bin, "This is part of the information for the other two cases, and I also asked for it with Ding Detachment. The detailed files are still stored in the Municipal Bureau. If you want to check it, it is more convenient than me. "

This is also the reason why Ma Jingbo wants to set up a joint investigation team. It is not easy for the lower-level departments to transfer files from the City Bureau. Although he used to work in the City Bureau, he is now transferred to the North City Bureau.

"I also participated in the investigation of two robberies seven years ago. I can briefly introduce you to them. Both robberies occurred in Yuhua District. In the first case, a clerk was shot and killed. It is the earthen pistol in the video. It has the same style, size, and color. Because it is different from ordinary pistols, the workmanship is rough, so I remember it very clearly.

There are also several points in common. For example, the suspects involved in the case were two people, the vehicles were all motorcycles, they used plastic gloves to collect gold and silver jewelry, and they all wore helmets to cover their faces when committing crimes. These distinctive characteristics of the crime. It is exactly the same as the previous two cases. "

Han Bin flipped through the file and asked, "Is there any surveillance video in the other two cases?"

Ma Jingbo said, "Yes, it should be kept in the City Bureau Archives. If you want to see it, you can figure it out by yourself."

Han Bin nodded and began to check the information of the first two cases. The prerequisite for the establishment of the ad hoc joint investigation team is that this case is related to the two cases seven years ago. Without certain evidence, Han Bin cannot. Because of Ma Jingbo's one-sided words, I believe it.

After a long while, Han Bin took a closer look at the two cases seven years ago. It did have a lot in common with the 403 robbery. Among them, there was a picture of a homemade pistol in the hands of the suspect, which was almost identical to the pistol in the 403 case.

Afterwards, Han Bin greeted him, left the meeting room, and reported the situation to Ding Xifeng by telephone.

...

Forty minutes later, Ding Xifeng rushed to the Chengbei branch in person.

Ma Jingbo and Han Bin greeted them in the yard ahead of time, and also alerted Chen Weixiong, the deputy director of criminal investigation in the Chengbei Branch.

Deputy Director Chen learned that Ding Xifeng was coming, and greeted him in the yard ahead of time, which attracted the attention of many police officers.

Ding Xifeng is a vigorous and resolute person. After getting out of the car, he exchanged a brief greeting and said straight to the point, "Director Chen, is there any new progress in the investigation of the 403 gold shop robbery?"

Chen Weixiong looked at Ma Jingbo on the side, "Captain Ma, you are the actual person in charge of the case, so you should report to the Ding Detachment."

"Okay." Ma Jingbo replied. He knew his old boss better than his new boss, and he was more accustomed to communication.

Afterwards, Ma Jingbo briefly introduced the progress of the case and at the same time expressed his own speculation.

Ding Xifeng finished listening, "Han Bin, what do you think?"

"I took someone to investigate the scene of the 403 case, but I don't know much about the two cases seven years ago. I need to read the detailed files to determine whether the three cases were committed by the same group of suspects."

"Okay, I brought the file, let's go and see it together."

The group returned to the conference room again, and, as mentioned by Han Bin, the surveillance footage of two cases seven years ago was played.

Due to the limitations of the times and technology, the clarity of the surveillance video seven years ago was far less than that of the 403 case, but the process of the suspect’s crime can still be clearly seen. Just like Ma Jingbo said, the three cases are somewhat vivid. Common features.

The two suspects, earthen pistols, helmet masks, plastic gloves, etc., judging from these clues, the characteristics of the three cases are very consistent. They are either the same group of suspects or imitating the crime.

Unlike the other team members, Han Bin has to look more carefully. In addition to the above details, he is also observing the characteristics of the suspects' body shape, walking posture, and gait to further judge whether they are the same group of suspects.

Within half an hour, Han Bin played back the video more than a dozen times and found a new clue after careful comparison...
