…
At 10: 30 am, Han Bin arrived at Jiufu Gold Shop on Dingxi Road. He only brought Zhao Ming and Zhang Shungu with him as the rest were still on vacation.
Han Bin had already informed Wang Xiao and Zhu Jiaxu to gather their team members to the crime scene as soon as possible. As for their vacation, they could only cancel it at the last minute.
The robbery at 403 Gold Shop had taken place at 9 am last night. Due to the lack of light, the investigation of the crime scene would be affected to a certain extent. It was very likely that the crime scene would be investigated again the next day. In order to prevent the crime scene from being destroyed, the police had been sending people to protect the scene.
The entrance of the shop was cordoned off with two policemen standing at the entrance.
When Han Bin showed his police badge, the policemen immediately saluted him.
Han Bin was not in a hurry to enter the shop. Instead, he looked around. The shop was located in the center of Qingdao, which was one of the more prosperous areas in the northern part of the city. There were many cameras installed around it, and the Dingxi Road Police Station was less than a kilometer away.
Han Bin retracted his gaze. There were also cameras installed at the entrance of the shop, and it seemed that the equipment was still working. He had to admit that the robbers were indeed bold.
Han Bin climbed over the cordoned off area and entered the shop. The shop was about seventy to eighty square meters, and there were rows of glass counters. The counters had been damaged, and there were a lot of broken glass scattered on the floor. The gold and silver ornaments on the counter had also been swept away.
There were some sporadic bloodstains on the counter and the floor. It looked a bit scary, but at the same time, it was important evidence.
From Ding Xifeng's description of the situation, the bloodstains were most likely left behind by the injured clerk. However, nothing was absolute. When the suspect smashed the counter, he might have been scratched by the glass, and the large amount of bloodstains might have been mixed with his blood.
If they really found the suspect's bloodstains, it would be a breakthrough in the investigation of the case.
Overall, the robbery scene of this gold shop was not much different from other gold shops.
There were also four surveillance cameras installed inside the shop. Three of them faced the glass counter, and one faced the cashier. As long as the surveillance cameras were not destroyed during the robbery, they could use the surveillance footage to perfectly reconstruct the crime scene.
This was crucial to the investigation of the case.
While Han Bin was inspecting the scene, the members of Second Squadron arrived one after another. These members were the elites of the criminal investigation system of Fujima City, and they quickly went from vacation to work.
"Wu wu …"
Just then, a black car stopped near the gold shop, and Ma Jingbo got out of the car.
He Yingsheng was quick to react and reminded, "The horses are here."
Han Bin also walked out of the gold shop and called out, "Captain Ma."
Ma Jingbo patted Han Bin's arm and glanced at the members of Second Platoon. He smiled and said, "Everyone is here."
"Team Ma."
"Hello, Captain Ma."
"Captain Ma, I heard that you've been promoted to the captain of the Criminal Investigation Unit of the North District Branch. Why don't you treat us to a meal?"
Ma Jingbo smiled. "I just took office not long ago. I haven't even sorted out my work, so how would I have time to treat you guys to a meal? When this case is over, I'll treat all of you to a feast, not one less. "
"Alright."
"How would we dare to reject Captain Ma's treat?" The team members cheered.
Han Bin said, "Captain Ma, why did you come in person? I said that I would go to the North District Branch to see you after inspecting the scene."
"I missed you guys. I haven't been on a mission with you guys for a long time, so I wanted to take this opportunity to reminisce." Ma Jingbo waved his hand. "Let's go, I'll introduce you guys to the scene."
"The crime was committed at nine o 'clock last night. Two suspects rode a motorcycle to the entrance of the gold shop, parked it in front of the door, and went straight into the shop. The two suspects had guns in their hands, so they quickly took control of the staff and immediately closed the shutter of the shop.
One of the staff tried to escape during the chaos, but one of the suspects hit him in the head with a hammer. Then, the shutter was pulled down, and the armed suspect took control of the staff, while the other suspect smashed the counter and stole the gold jewelry.
The entire crime was committed in a very short time. From the moment the shutter was pulled down to the moment it was pulled up again, the two suspects left the gold shop on their motorcycles. Only then did the staff have time to call the police. By the time the police arrived, the suspects were long gone. "
Han Bin asked, "No one suspected anything when the suspects pulled down the shutter, and the neighbors didn't help to call the police?"
"It was already nine o 'clock at night, and there weren't many people around. Some shops were closed, and even if the shops weren't closed, the staff wouldn't stand at the door and watch. When the suspects entered the gold shop, they didn't attract any attention. After that, we visited a 24-hour convenience store.
At the time of the crime, there were two staff in the convenience store, but they were changing shifts, so they didn't see the suspects enter the gold shop. However, they said that they heard a shout during the crime, and it was most likely from the injured staff.
One of the staff stood at the door to check, but there was nothing unusual on the street. The gold shop had already pulled down the shutter, so they thought that it was about to close, so they didn't think much of it and returned to the shop. "
Han Bin said, "Only two suspects? Aren't there any lookouts outside the shop? "
"From the current surveillance footage and clues, we haven't found a third suspect yet."
"What about the blood at the scene?"
"It should be the staff's blood. So far, we haven't found any blood samples from the second suspect."
As the criminal investigation team of the North District Branch had already investigated the crime scene, it was much easier for Han Bin to bring his men to investigate the crime scene. All they had to do was understand the situation on the spot and have an accurate impression of the crime scene.
Then, Han Bin and the others followed Ma Jingbo back to the North District Branch.
In the conference room, Han Bin met Hao Jianbo and Zhao Renqi again. As they had drunk together, they were more familiar with each other, and it was easier for them to work together.
Then, Han Bin looked at the surveillance footage of the crime scene. The video was very clear, showing two suspects riding a red motorcycle and stopping at the entrance of the gold shop. They wore helmets and entered the shop, then switched to the surveillance footage of the inside of the gold shop.
Judging from their physiques, the suspects should be two men. One of them was wearing a black jacket and dark blue pants, while the other was wearing a fur collar jacket and black pants. The man on the motorcycle wore black leather gloves, while the other man put on transparent plastic gloves after entering the shop.
From this point, the suspects had done their homework beforehand. The risk of robbing a busy city was very high, so they had to move quickly. The most time-consuming part of robbing a gold shop was collecting the gold and silver jewelry in the shop. The wider and thicker the gloves, the more inconvenient it was to collect the jewelry. The tight-fitting plastic gloves were light and wouldn't leave fingerprints, so they were the most suitable.
The two men were both carrying bags. After entering the shop, the man on the motorcycle took out a handgun from his bag, while the other man pulled down the shutter. At this moment, the staff member who was closer to the door tried to escape from behind the two suspects.
Unfortunately, this action was seen by the suspect who pulled down the shutter. He took out a hammer from his bag and smashed it at the head of the escaping staff member without hesitation.
"Peng!" Fresh blood spurted out. The shop assistant screamed and fell to the ground.
The man with the gun rushed over to help and kicked the injured staff member while the other suspect continued to pull down the shutter.
After the shutter fell, the two suspects worked together. The man with the gun was in charge of guarding the shop, while the other man smashed the glass counter with a hammer, quickly collecting the gold and silver jewelry in the shop.
Bang, bang, bang! The sound of glass being smashed was endless.
A few staff members were so scared that they hid at the side. Having learned their lesson, they didn't even dare to make a sound, let alone call for help.
After collecting the gold and silver jewelry, the two suspects left the gold shop, and the video switched to the surveillance camera outside the shop.
The two suspects got on the motorcycle and quickly disappeared from the surveillance camera …
After watching the video, Han Bin only had three words left in his mind: clean, efficient, brutal …
After Han Bin finished watching the video, Ma Jingbo asked, "How is it? Did you find anything? "
Han Bin thought for a moment. "The sound of glass breaking was so loud, and the convenience store was only about 20 meters away. Logically speaking, the staff member should have heard it."
Ma Jingbo said, "Not bad, this is indeed suspicious. We'll give them a statement later. If the two of them are hiding something, we must find out the reason.
Captain Han, did you find anything else? "
Han Bin continued, "According to my observation, the man with the gun had an injury to his leg, and he should be around 45 years old. The man with the hammer is younger, probably less than 30 years old. Of course, this is only a rough observation from the video. If the technical department can collect the suspect's footprints, we can make a more accurate judgment. "
Ma Jingbo spread his hands. "Unfortunately, there are no footprints of the suspects at the scene."
Zhao Renqi was a little surprised. "Captain Han, I've heard of the technique of judging height from video. These suspects didn't even show their faces, and you can tell their age?"
Han Bin said, "I've learned some footprints identification techniques. I can roughly determine the suspect's age based on their walking posture, gait, and other characteristics."
The people from Second Squad acted as if it was natural, but the people from the North District Branch were skeptical. Although they all knew about footprints identification, they knew that it was a complicated subject. It was hard to believe without seeing it with their own eyes.
Ma Jingbo smiled and didn't explain too much. Whether it was a mule or a horse, he would know when he caught the suspect.
Han Bin said, "Captain Ma, I heard from Detachment D that there were two gold shop robberies seven years ago. I wonder what they have in common with this case."
Ma Jingbo took out two brown paper bags and passed them to Han Bin. "These are some of the information for the other two cases. I also got them from Detachment D. The detailed files are still stored in the Municipal Bureau, so it's more convenient for you to look at them. "
This was also the reason why Ma Jingbo wanted to set up a joint investigation team. It wasn't easy for the lower-level departments to get the files from the Municipal Bureau. Although he used to work in the Municipal Bureau, he was transferred to the North District Branch now. It was inconvenient for him to have one less identity.
"I also participated in the investigation of the two robberies seven years ago, and I can give you a brief introduction. Both robberies happened in Yu Hua District. In the first case, a shop assistant was shot to death, and the gun used was the homemade handgun in the video. It's the same style, size, and color. Because it's different from ordinary handguns, I remember it very clearly.
There are also a few common points. For example, there were two suspects in the case, and they both used motorcycles to transport themselves. They both used plastic gloves to collect gold and silver jewelry, and they both wore helmets to cover their faces when committing the crime. These distinctive characteristics are exactly the same as the previous two cases. "
Han Bin flipped through the files and asked, "Are there any surveillance videos for the other two cases?"
Ma Jingbo said, "Yes, they should be kept in the Municipal Bureau's archives. If you want to see them, you'll have to figure out a way."
Han Bin nodded and began to look through the information of the previous two cases. The premise of establishing a joint investigation team was that this case was related to the two cases from seven years ago. Without a certain amount of evidence, Han Bin could not believe Ma Jingbo's side of the story.
After a while, Han Bin carefully looked through the two cases from seven years ago. There were indeed a lot of similarities with the 403 Robbery Case. There was a picture of the handgun in the suspect's hand, and it was almost identical to the handgun in the 403 Robbery Case.
Then, Han Bin said goodbye and left the conference room. He then called Ding Xifeng to report the situation.
…
Forty minutes later, Ding Xifeng personally arrived at the North District Branch.
Ma Jingbo and Han Bin went to the yard to greet him in advance. They even alerted the deputy director of the North District Branch, Chen Weixiong, who was in charge of criminal investigation.
When Deputy Director Chen heard that Ding Xifeng was coming, he also went to the yard to greet him in advance, which attracted a lot of attention from the police officers.
Ding Xifeng was a swift and decisive person. After he got out of the car, he greeted them briefly and went straight to the point. "Director Chen, are there any new developments in the 403 Gold Shop Robbery Case?"
Chen Weixiong looked at Ma Jingbo, "Captain Ma, you are the actual person in charge of the case. You should report to Detachment D."
"Okay." Ma Jingbo responded. He knew his old boss better than his new boss, and he was more used to communicating with him.
Then, Ma Jingbo briefly introduced the progress of the case, and at the same time, stated his speculation.
After Ding Xifeng listened, he asked, "Han Bin, what do you think?"
"I brought people to investigate the 403 Case, but I don't know much about the two cases from seven years ago. I need to read the detailed files to determine if the three cases were committed by the same group of suspects."
"Okay, I brought the files. Let's go take a look."
The group returned to the conference room again, and under Han Bin's suggestion, the surveillance footage of the two cases from seven years ago was played.
Due to the limitations of time and technology, the clarity of the surveillance footage from seven years ago was far less than the clarity of the 403 Case video. However, the process of the suspects committing the crime could still be clearly seen. Just like Ma Jingbo said, the three cases had some distinct characteristics in common.
Two suspects, homemade pistols, helmets, plastic gloves, and so on. From these clues, the characteristics of the three cases were very similar. It was either the same group of suspects, or it was a copycat crime.
Unlike the other team members, Han Bin looked more carefully. In addition to the above details, he also observed the suspects' body shape, walking posture, gait, and other characteristics to further determine whether they were the same group of suspects.
Within half an hour, Han Bin continuously replayed the video more than ten times, and after careful comparison, he found a new clue …
