Chapter 873: Starting from the case three years ago
Now that the direction of handling the case has been determined, the only thing left 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 was 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 back then.
On the one hand, the amount robbed was relatively small, only 1,900 yuan.
On the other hand, if there are no elderly people at home, this is actually theft.
The amount of the burglary was only 1,900 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 3,000 yuan. Under normal circumstances, the person who is stolen doesn’t care much, and the police station is not particularly active.
So 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 did not go all out.
After obtaining some basic information from that year, Lu Chuan began to make work arrangements.
"For the First Squadron, the focus is 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 determined that the suspect had stayed He followed the footprints and analyzed some basic characteristics of the other party.
Male, 1.73 meters tall, about 70 kilograms, left-handed!
Aged between forty and forty-five.
"He conducted a key screening based on the height, weight and age characteristics of the suspect."
"Yes!"
"Second Squadron," Lu Chuan looked at Sun Biao : "You, this group, focus on checking each other's relatives."
"All direct blood relatives and collateral relatives must be checked in place, especially those living in Haizhou City, and 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 collected fingerprints."
There were fingerprints left by the suspect at the robbery scene, so at that time the Tianshan District Criminal Police Brigade They were relatively optimistic when they first started 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, the comparison was not 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 family members who were robbed.”
“Especially after the male owner withdrew money from the bank, there are people who may know about it.”
"The files of that year record that they had withdrawn 100,000 yuan only three days before the incident."
"The criminal suspect should have known the existence of the 100,000 yuan, otherwise he would not have been able to 1,900 yuan to take such a huge risk to commit a house robbery.”
“So, focus on investigating the male owner’s friends, such as who he drank with before the crime, and who disclosed the amount of 100,000 yuan. "
"Yes!"
Compared to when the Tianshan District Criminal Police Brigade investigated this case, Lu Chuan's arrangements 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 is different. All personnel from the three squadrons of the entire brigade are involved.
In addition, this time there are physical characteristics and age range of the suspect, so the accuracy of the investigation will be much higher.
Three days passed quickly.
Although Lu Chuan has made very detailed arrangements and has thought of many things. It can be said that all aspects of this investigation have been arranged, but the results of the investigation are not satisfactory.
"Team Lu, I have conducted a complete investigation on all the relatives of the robbed person."
The news on 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.
We have even conducted research on several new cities in the surrounding areas.
We were able to sort out 128 relatives of the robbed family, 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. What was collected was not compared with the suspect’s.”
On the other hand, Wang Zhaokai also found 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 been completed. The fingerprints of the persons who meet the characteristics of the criminal suspects have been focused on, and none of them were found after comparison."
"The crime occurred that year. The temporary residents during this period were renting houses in the community. We also conducted an investigation and found a total of 6 people who matched 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 remaining two people, one of them died in a car accident a year ago."
"There is another one in Tianzhou City. I asked my colleagues there to help collect fingerprints, and the results just came back...the comparison was not successful."
The two groups, Wang Zhaokai and Chen Jiang, I basically didn't sleep much in the past three days. I carefully conducted a large-scale screening of the people within my range, but it was a pity that I didn't get the desired results.
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."
"There are four members of their family. The paralyzed old man cannot go out, and there is no one with him. Communication, there is basically no possibility of leaking the news.”
Sun Biao’s report began.
