Chapter 872 Clues
After completing the fingerprint identification analysis of the suspect and finding that the three cases were all the same suspect, Lu Chuan made a guess about the suspect's next actions.
“Although the criminal suspect committed the crime from BJ City, he fled all the way to Haizhou City.”
Lu Chuan wrote the names of cities one after another on the whiteboard.
“These dozen cities are places where criminal suspects stayed while escaping.”
This information comes from two sources.
The first is the criminal police brigade where Chen Bing works in Beizhou City. They have some information about the whereabouts of criminal suspects over the years.
On the other hand, there are some places that Chen Bing has traveled in the past few years after his retirement.
"Have you noticed a strange place?"
Lu Chuan pointed to the address on the whiteboard: "The probability of Haizhou City appearing is very high."
Indeed.
It is proved in chronological order that the suspect traveled from one city to another, but in no case more than three cities, and would return to Haizhou City once.
Moreover, this time generally does not exceed one year.
“In addition, everyone should pay attention to the geographical distribution of these cities. They are basically around Haizhou City.”
Including Beizhou City, it is actually also around Haizhou City.
"So, is it possible that the criminal suspect is from Haizhou City? Even if he is not from Haizhou City, is there someone or something in Haizhou City that the other party can't let go of and will come back every once in a while? "
" Captain Lu, you mean that the other party may not have left Haizhou City directly and is still here? "
Chen Jiang frowned.
Details are important in solving crimes.
A hair at the crime scene may become an important clue to solving the case.
But in addition to the details, the direction of solving the case is also important.
For example, Lu Chuan's judgment is that if the other party is still in Haizhou City, then the energy and focus of the Criminal Police Brigade will be within Haizhou City.
But if it can be determined through certain clues that the other party has left Haizhou City, then everyone’s focus will be to spread the fish out.
Focus on checking what means of transportation the other party might take to leave.
There are only so many people in the criminal police brigade and only so much power. If the direction is wrong, it may go in the opposite direction.
That’s why Chen Jiang raised this question.
Lu Chuan shook his head: "Now we cannot draw a conclusion based on these inferences as to whether the other party is still in Haizhou City."
"I mean, since the other party lives in Haizhou City, If there is any connection with the city or Haizhou City, should we use this direction as a breakthrough point?"
Lu Chuan sat back on his chair.
“It proves that the criminal suspect is very different from the criminal suspects we have encountered in the past.”
"The other party committed a crime 15 years ago and another three years ago, and we can't guarantee whether the other party had any other criminal cases during this period."
Lu Chuan explained his judgment: "But after so many years, we have about There is very little information about the other party."
"If Chen Bing hadn't killed us, we wouldn't even be able to confirm the other party's footprints and complete fingerprints."
"In addition, the other party has been there for more than ten years. He is very experienced in absconding and escaping."
"No, if we keep chasing after him, it is very likely that we will be led by the other party, and it will be difficult to solve the case in a short time."< br>
This conclusion was reached by Lu Chuan after careful analysis.
Different people have different specialties, and some people are good at hiding themselves.
Lu Chuan did not doubt his own abilities. Instead, Chen Bing's criminal police team had been chasing the other party for 15 years and traveled to more than a dozen cities, but they could not find the other party.
There was also the robbery in Tianshan District three years ago.
The Tianshan District Criminal Police Brigade also invested a lot of police force in that case, but three years later, there is still no major discovery.
Also, after Chen Bing retired, he did nothing for four years and always wanted to find someone else. What was the result?
So solving this case cannot start directly with the criminal suspect himself.
"What do you mean?"
Wang Zhaokai looked at Lu Chuan, wanting to know the other party's final decision.
Since Lu Chuan took charge of the High-tech Zone Criminal Police Brigade, the crime detection rate of the High-tech Zone Criminal Police Brigade has skyrocketed.
Not only that, some cases that are difficult to detect in other cases will also be asked to help from the High-tech Zone Criminal Police Brigade.
The reason for this is not because the people in the High-tech Zone Criminal Police Brigade suddenly became powerful.
The people in the High-tech Zone Criminal Police Brigade are still the same, but the leaders have changed.
Wang Zhaokai naturally had no reason to doubt Lu Chuan's judgment.
"In my opinion, start investigating the robbery case three years ago!"
The case three years ago?
Sun Biao was a little confused: "Captain Lu...the case three years ago...wasn't it easy to investigate?"
Lu Chuan nodded, he knew what Sun Biao meant.
Lu Chuan himself was involved in the robbery case three years ago to a certain extent. The Tianshan District Criminal Police Brigade also spent a lot of effort on it, but the case has never been solved.
Moreover, three years have passed, and it would probably be very difficult to look back at that case now.
In Sun Biao's view, it is not even easier than the robbery and murder case 15 years ago.
“There were very few clues in this case, so the detection process was difficult. However, because Chen Bing was murdered, the murderer left a lot of footprints and fingerprints at the scene, as well as the trait of being left-handed.”
Lu Chuan looked around: "No one has an in-depth understanding of the case back then. I have read the files of the case back then."
"The suspect did not use violence to open the lock when he sneaked into the house that was robbed. way.”
"And there are no signs of being opened on the lock, which means that the suspect at the time should have used a key to open the door lock."
"Based on this, the Tianshan District Criminal Police Brigade determined the suspect It is possible that the person knows the person who was robbed."
Chen Jiang was confused: "Team Lu... If the suspect and the person who was robbed know each other, then he should know something about the other person's family situation. There is a paralyzed old man at home..."
Sight!
By the way, the old man has poor eyesight.
There are severe cataracts.
Lu Chuan nodded, knowing that Chen Jiang had figured this out.
“In addition, another detail is that the family was robbed on the day of the crime, and there should not be anyone there.”
“The file shows that the family originally planned to take the old man to the hospital for examination that day. Yes, it was because the male owner had something to do and he didn’t go there. "
"Furthermore, according to the information provided by the male owner at the time, their family had withdrawn 100,000 yuan from the bank a few days ago. of cash.”
"On the day of the crime, it was because the company had something to do temporarily, so he did not take the old man to the hospital for a check-up, and the cash he got back was also taken away by him."
"So at that time, the Tianshan District Criminal Police Brigade Bian is relatively sure that an acquaintance committed the crime, but after some investigation, no suspect was identified. "
"Now, my suggestion is to re-investigate the social relationship of the person who was stolen!"
