Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

As for the judgment of left-handedness, it was inferred from the fingerprint marks left by the dagger held by the opponent.

Holding the knife in the left and right hands, you can judge by the wrapping direction of the fingerprints.

At the same time, Lu Chuan also found some skin residue in the nails of Chen Bing's right hand.

During the chase and fight between the two, Chen Bing should have injured the other party.

"Go back to the team!"

After finishing the work at the scene, Lu Chuan led the people back to the criminal police brigade.

There is still a lot of work to do next. Lu Chuan needs to identify and analyze the information collected at the scene, especially fingerprints and footprints.

On the other hand, the more important thing is to notify Chen Bing’s family members and his employer.

Let Sun Biao handle this matter.

At the same time, Lu Chuan made a brief report on the relevant situation to the branch director.

No matter what level a murder occurs, it is worthy of attention at all levels. This case in particular is a little more special, so the branch office also reported it to the city bureau.

But neither the branch nor the city bureau put particularly great pressure on Lu Chuan.

Because both the city bureau and the branch bureau know about this case, Lu Chuan will definitely go all out.

What's more, if even Lu Chuan can't solve this case, then no one from the Haizhou City Public Security Bureau can solve this case.

However, the detection of the case was not very smooth.

First of all, Wang Zhaokai was the first to send back bad news.

The person was lost, but it was not without gain. They found the suspect's short-sleeved shirt in a garbage dump.

"I suspect that the other party has left Haizhou City."

Wang Zhaokai looked ugly.

During the investigation of this case, the Criminal Police Brigade has contacted Chen Bing's former unit and obtained the files of that year's case.

This suspect is quite cunning.

Although the other party's information has not been effectively confirmed, and the other party's name and circumstances are not known, Chen Bing and the others have touched each other several times in the past ten years, but they have always passed by.

"This guy is very cunning. We found some information about him in the Gree air-conditioning repair station where he works, but it was all false."

The news reported by Chen Jiang is relatively more specific.

"This person rented a house in North Lane 1 of Qingyun Road. After Chen Bing got this information at the air-conditioning repair station, he wanted to check out the house he rented this morning."

"But I didn't expect..."

In one day, the entire process of Chen Bing's murder was figured out.

According to the eyewitness testimony of two pedestrians in the North Alley of Qingyun Road, Chen Bing and the criminal suspect happened to bump into each other, and then a chase and conflict broke out.

The two men chased from Bei 1st Alley to the vicinity of Beisan Alley.

Then something bad happened.

"Over the years, the other party has been rumored to be in many cities, using false identities to rent houses."

Chen Jiang continued: "And I went to the house the criminal suspect rented in Beiyi Lane. The other party was very cunning and cautious."

"The house faces the street at the corner of the second floor. There are two directions to the left and right where you can jump off the building and you can observe the situation at three intersections."

"The layout inside the house is also very simple. The other party should be ready to escape at any time."

"So, I think the other party should have left Haizhou City as soon as possible after the incident."

Chen Jiang made this conclusion based on the situation of the file and the process of solving the case. In fact, this kind of case is very difficult to solve.

When the police arrest a fugitive, they are not afraid of him hiding his name in one place.

I am afraid that the opponent is always moving. It will be very difficult to catch him here today and there tomorrow.

Because there is always a certain lag in information when the police are chasing. If the other party is very cautious and often changes places, then this lag is equivalent to always leading the police by the nose.

Just like when Chen Ping and others tracked each other down, they found the information and chased them, but the person was gone.

Lu Chuan took a deep breath.

Compared with the situation on the other two sides, the progress on his side is actually great.

"Do you have any other opinions?"

Lu Chuan stood up and walked to the whiteboard.

"If not, let me tell you about the current situation here."

Everyone straightened their backs and looked at Lu Chuan seriously.

"First of all, let me talk about the findings here. The specific identity of the criminal suspect has been finally determined through fingerprint comparison."

Lu Chuan quickly discovered this.

When it turned out that there was only half a fingerprint, Lu Chuan still felt familiar. He also checked some fingerprints that he had compared before.

But because there were other things to do at that time, Lu Chuan only had time to take a look, so he didn't see too much.

Today, the other party's complete fingerprints were extracted from the murder weapon. Although the target was not found in the fingerprint library, Lu Chuan compared the other party's fingerprint information with the suspect in another case.

"Do you still remember that a home invasion and robbery case occurred in Tianshan District three years ago?"

"Tianshan District? The one on Qianjin Street?"

Chen Jiang remembered a case.

Three years ago, a ridiculous home invasion and robbery occurred in Natural Gas.

Nonsense, because the suspect only robbed 1900 yuan.

As for the person who was robbed, there was a paralyzed old man at home. His eyes were still suffering from severe cataracts and he could not see anything.

As a result, no characteristics of the criminal suspect could be described. There were only some footprints scattered in the living room, but only some basic information such as height, weight, age, etc. of the suspect could be determined.

The fingerprints were found, but unfortunately the comparison was not successful at that time.

At that time, this case was investigated for a period of time. Later, because the amount of robbery was indeed relatively small, it was finally settled there.

"Yes, that's the robbery on Qianjin Street."

Lu Chuan showed the report in his hand to everyone.

"At that time, the Tianshan District Criminal Police Brigade brought over the fingerprints and asked me to check them. Because the person's information did not exist in the system, the comparison was not successful at that time."

"Now, it is confirmed that the murderer who killed Chen Bing is the same person who committed the robbery on Qianjin Street three years ago!"

Lu Chuan continued: "When Chen Bing first came to our criminal police brigade, he showed me a photo of half a fingerprint of the criminal suspect who committed a robbery and murder case in Beizhou City 15 years ago. I felt familiar with it at the time."

"The fingerprints extracted from the murder weapon that killed Chen Bing this time confirm that these three people are the same person!"

There is no conclusive evidence from the evidence to identify the suspect who was responsible for the murder of Chen Bing.
Through the comparison of several fingerprints, Lu Chuan determined that the suspect who killed Chen Bing was the suspect who committed the robbery and murder in BJ City 15 years ago.

He is also a criminal suspect who committed a robbery on Qianjin Street in Tianshan District three years ago. (End of chapter)
