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

Chapter 873: Starting from the case three years ago
Now that the direction of handling the case has been determined, all that remains is to go all out.

But three years have passed, and many things have changed.

When Lu Chuan brought people back to the house that had been stolen three years ago, he learned that the paralyzed old man had died of illness last year.

So this brings a certain degree of difficulty to solving the case.

Lu Chuan originally wanted to roughly determine the characteristics of the suspect through some of the old man's descriptions.

But it doesn’t matter.

Since I didn't get any useful information from the old man back then, it would probably be difficult to ask again later.

Tianshan District Criminal Police Brigade.

Wang Gang personally handed over the files from that year to Lu Chuan.

"We later studied this case, but gave up because there were too few clues."

Lu Chuan nodded.

In fact, this case did not receive so much attention at the time.

On the one hand, it was because the amount robbed was actually relatively small, only 1900 yuan.

On the other hand, if there are no elderly people at home, this is actually theft.

The amount of money involved in the burglary was only 1900 yuan, so it would be difficult to file a case.

Nowadays, if you want to file a theft case, you don't have to pay more than 3000 yuan. Under normal circumstances, the person who is stolen doesn't care much, and the police station is not particularly active.

Therefore, the Tianshan District Criminal Police Brigade spent some effort, but after finding nothing, the case was left hanging.

To be honest, when they solved this case, they didn't go all out.

After obtaining some basic information from that year, Lu Chuan began to make work arrangements.

"For the First Squadron, we will focus on investigating the neighborhood relations of the stolen homes."

In the conference room, Lu Chuan began to arrange relevant work.

"We should pay special attention to families whose financial conditions are difficult, or who have elderly people living alone or whose children often go out."

At the scene of Chen Bing's murder, Lu Chuan analyzed some of the suspect's basic characteristics by identifying the footprints left by him.

Male, 1.73 meters tall, about 70 kilograms, left-handed!

Aged between forty and forty-five.

"He conducted a focused screening based on the suspect's height, weight and age characteristics."

"Yes!"

"Second Squadron," Lu Chuan looked at Sun Biao: "You guys focus on investigating each other's relatives."

"All direct blood relatives and collateral relatives must be investigated in place, especially those living in Haizhou City, where the investigation must be focused."

"The Tianshan District Criminal Police Brigade conducted a screening of all the relatives of the stolen homes, and many people also had their fingerprints collected."

There were fingerprints left by the suspect at the robbery scene, so the Tianshan District Criminal Police Brigade was relatively optimistic at the beginning when handling the case.

If it is determined that an acquaintance committed the crime and left fingerprints, then all you need to do is touch all the acquaintances, collect the fingerprints, and compare them to determine the identity of the other party.

But unfortunately, no comparison was successful.

"You will treat it as a case and investigate it again. People whose fingerprints were collected before will also be collected again this time."

"Of course, the other party may not be in Haizhou City currently, so you should pay more attention to the physical characteristics and age characteristics of the criminal suspects and conduct key investigations." "Yes!"

Lu Chuan looked at Sun Biao from the third squadron again.

"The focus of the Third Squadron is to investigate the friends of the robbed family members."

"Especially after the male owner withdrew money from the bank, there is someone who may know about it."

"The files from that year record that they had withdrawn 10 yuan and it was only three days before the crime occurred."

"The criminal suspect should have known about the existence of the 10 yuan, otherwise he would not have taken such a big risk to rob the house for 1900 yuan."

"So, we focused on investigating the male owner's friendships, such as who he drank with before the crime, and who he disclosed about one hundred thousand yuan."

"Yes!"

Compared with when the Tianshan District Criminal Police Brigade solved this case, Lu Chuan's arrangements here were much more detailed.

After all, the Natural Gas Criminal Police Brigade only handed over this case to one squadron, and several criminal police officers were responsible for this matter.

But this investigation by the High-tech Zone Criminal Police Brigade was different. All personnel from the three squadrons of the entire brigade were involved.

In addition, this time the suspect's physical characteristics and age range are available, so the accuracy of the investigation will be much higher.

Three days passed quickly.

Although Lu Chuan had made very detailed arrangements and thought of many things. It could be said that all aspects of this investigation had been arranged, but the results of the investigation were not satisfactory.

"Army Corps, I have conducted a complete investigation on all the relatives of the robbed person."

The news from Chen Jiang's side is very bad.

In three days, Chen Jiang came here with more than 20 people from the Second Squadron, but he traveled all over Haizhou City.

Several new cities in the surrounding areas have even been explored.

It was possible to sort out 128 relatives of the person who was robbed, and all of them were investigated.

"There are a total of 7 people among these people who match the age and physical characteristics of the criminal suspects. We focused on these 7 people. However, on the day Chen Bin was killed, these people all had alibi certificates. The fingerprints were mine. The collected information was not compared with the suspect’s.”

On the other side, Wang Zhaokai also gained nothing.

"I conducted an investigation on all the people who lived in the community at that time, not just in that unit building, but all the people in the community who matched the age characteristics and height characteristics of the criminal suspect."

"The investigation of the permanent residents has now been completed. The fingerprints of persons who meet the characteristics of criminal suspects have been focused on, and none have been found after comparison."

"The temporary residents during the time of the crime were renting houses in the community. We also conducted an investigation and found a total of 6 people who met the characteristics of the suspects."

"We have found four of these six people, and they also live in Haizhou City. After investigation, there is no suspicion."

"Of the two remaining, one died in a car accident a year ago."

"There is another one in Tianzhou City. I asked my colleagues there to help collect fingerprints. The results just came back...the comparison was not successful."

Wang Zhaokai and Chen Jiang basically didn't sleep much in the past three days. They carefully conducted a large-scale screening of the people within their range, but unfortunately they did not get the results they wanted.

Lu Chuan looked at Sun Biao, but the other party also shook his head.

"I have conducted an investigation on all the outsiders who came into contact with the other party's family before the incident."

"They are a family of four. The paralyzed old man cannot go out, and there is no one to communicate with him. There is basically no possibility of leaking the news."

Sun Biao's report began.
