The social software dating case selected by Cui Qishan, or the face-to-face murder case, is a difficult case in the new era.
First of all, there is a delay in the discovery of such cases. The victim travels to a different place and cannot be contacted for several days. It is easy to be regarded as normal by friends. By the time the report is made, a long time has passed.Moreover, the reporter usually reports the crime at the place of departure, not the place where the crime occurred, which makes it difficult to use the police.
Sometimes it is not even known where the victim really went and the level of trouble is even higher.
Secondly, there is still the issue of identification of the corpse.Disappearance and death are given different degrees of attention, especially for the victim who is dating Pao Mianji, saying that he (she) went to love, so it is not necessarily true that he or she eloped to Hoh Xil.And to hide the corpse, the murderer who has plenty of time in a different place still has a good chance.
The key to solving the case mainly lies in the link of technical investigation.After the network is real-named, the identities of most people can be traced and traced. Therefore, ordinary remote face-to-face encounters with passionate murders can basically be cracked.
The trouble lies with some criminals who are prepared.
Anonymous phone cards, fake identities, and so on, although the police also have such fences, technical investigations, etc., but if the murderer uses forged identities, then so on, and committing crimes In the middle, if you know a little anti-reconnaissance skills, such as pulling out the phone card, changing the contact information, so what, how will the police respond.
To be honest, there are not many strategies to deal with it.This is one of the reasons why human trafficking has been banned repeatedly, not only because of economic factors, but also because it is difficult to detect.
If the case can be detected, especially if it is easy to detect, its economic efficiency itself will also decline.
In addition, face-based murder is similar to random crimes to a certain extent.
The social software for hooking up with guns is usually socialized by strangers. Whoever you swipe to and who you can date are largely random.The murderer may have a pattern, but such things as deciphering the pattern usually appear in serial dramas. Movies are not liked because the verification process is too long.
For the police, to solve such a case, the normal process is to see whether the technical means are not enough.Fortunately, the domestic software servers are well controlled, and the murderer's technical level is usually not high, but there is an exception to everything...
Of course, Cui Qishan is now betting that this case is not an exception.
The nine policemen he selected each have long-term experience in technical work, not necessarily good at technology, but they are familiar with various technical means, know who to call in any situation, and are extremely experienced. A good criminal policeman can not only carry out investigation work independently and in a team, but also be able to standardize things, know how to collect evidence, and can withstand the strict requirements of the two courts.
In essence, the policemen he was looking for were similar to Pang Jidong's type of criminal policemen.Pang Jidong learned so much knowledge of forensic botany from Jiang Yuan, and his purpose was to be able to use forensic botany to solve cases.
Cui Qishan was very optimistic about this, and led the criminal police into the work with enthusiasm.
He believed that in terms of the professionalism of the task force he formed, it would be no problem to solve the social software dating case, not to mention that it would be easy to grasp.
Cui Qishan planned to restart the case first
At the same time, Tao Lu personally led the team, and a group of people studied the villagers of Fangxia Village.
Jiang Yuan pulled out the technology of footprint identification as usual, and first classified the footprints that had entered the bedroom.
The footprints left by the police were eliminated first, and then the footprints that came in with other villagers to watch the excitement were eliminated. There were still more than a dozen left, and there were even more suspects.
Liu Sheng was in charge of this, and said with a frowning face: "Nowadays, people are running all over the place, and most of the murderers took the opportunity to go out. At the beginning, they might be afraid of being suspected, and they might stay in the village. Even if they run away, it is easy to find them." Come out, after such a long time, if I stay in the village again, I will doubt his IQ."
Liu Sheng seemed to be complaining, but he was actually complaining.
Asking dozens of people in his brigade to look up the addresses of thousands of people... Just contacting is exhausting. If you don't complain, the work can't be completed.
Tao Lu frowned and asked, "How many people were there in the village at the time, but not now?"
"There must be hundreds of people. There are fewer and fewer people in the village. This Fangxia Village is still good. Some middle-aged people stay in the village to contract land orchards, do farming or something, or give to those agricultural companies. Doing things, but young people still leave a lot, and some old people have to help take care of their children..." Liu Sheng said difficulties, troubles on his mind.
Originally it was an ordinary job, but with the addition of the number of people, this job is no longer ordinary.
Contacting hundreds of people, confirming their addresses, and trying to call them back, if they really can't be called back, and sending someone to the local area to inquire... Just thinking about these things makes one's scalp tingle.
Tao Lu thought for a while and said, "If the elderly are removed, there will still be minors..."
Jiang Yuan sat on the other side of the table, coughed twice, and said, "You can't screen like this. Whether you were in the village or not was all based on the records of the police involved. I read the record sheet, and it was also the police record of the police station along Liugouyan. Yes, this is unbelievable."
Tao Lu was refuted for a while, but he didn't feel uncomfortable, and simply said: "That's true."
In fact, there is still a case of secretly entering the village. If you want to prove who was in the village that day, you can still play with it at the stage of the current case-when there are conflicts or doubts, you can at least check and ask. Now it has been more than two years. It all depends on the records, and the records are not reliable...
Jiang Yuan didn't use EQ for Tao Lu. We still have to cooperate with 9 corpses, so he said directly: "Elders and minors can't be screened out either. I saw the photos of the corpses, and the murderer used an arm-long The force arm of the ax is very long, depending on the position of the hand, even if it is used by an elderly person or a minor, it is powerful enough to smash the victim's head and face."
Jiang Yuan glanced at Tao Lu and saw that he could accept it, so he continued: "The elderly in Fangxia Village have been farming for a long time and have strength. Even if a man is five or sixty years old, using an ax is enough to kill the victim's family. And made similar wounds."
"As for minors... Minors now grow very fast. At the age of 14, they may be 1.8 meters tall, or they may weigh 180 kilograms. They cannot be excluded either."
Tao Lu spread his hands: "That is to face the whole village? This is a big project."
Comparing the footprints is a simple matter, the problem is, how to compare when people are outside?
Let the other party take a picture of the footprints?It feels clever, but in theory it's illegal.
In the face of a murder case, the safest and most legal method is to call and ask for the address of the other party, and carefully invite the other party to return to the village. If he is unwilling, send someone to the local area to collect evidence.Including footprints, it is also the most normal for the police to take by themselves.
This is what Liu Sheng complained about. If the work could be completed, he wouldn't call too much, but it was obviously a job that couldn't be completed. If he didn't call, the case would be delayed with him.
Jiang Yuan smiled and said, "You still worry about doing useless work."
This is what Jiang Yuan often encounters.Commanders are faced with numerous clues, and it is impossible to devote themselves to every clue. Saturated investigation sounds cool, but it is not cool when the bill comes out.
And this case is just at the stage of restarting, Tao Lu certainly can't send out the reserve team at this time.
But Jiang Yuan is different. The conclusions drawn by Jiang Yuan's analysis are often backed by high-level skills.
Therefore, from Jiang Yuan's point of view, this input-output ratio is relatively good.
As far as a footprint identification is concerned, there is a certain trust gap between the two parties.
Tao Lu's thinking was exposed, he laughed, and didn't take it seriously at all, saying: "You just have to have confidence, in this case, you are the main one!"
He gave Huang Qiangmin all the advance payment. If he didn't trust Jiang Yuan at this time, he would have sold himself.
Jiang Yuan nodded and said: "Then we will still target the whole village, including the relatives of the victims, and pull them out according to the list in the address book. Then, we will rank these people in order and investigate wave after wave. "
Liu Sheng heaved a sigh of relief, and said, "That's about the same. It works. Who should be selected in the first wave? Relatives of the victim living in the village?"
"The footprints in the house have been crushed, too many people came in and out, and some villagers went in later, but I can sum up, I can still draw a certain range...height is more than 165 cm, male, weighing more than 130 catties, Right-handed, with a close relationship with the victim, able to enter the bedroom..."
Jiang Yuan has already used skills such as footprint identification, tool identification, and bloodstain analysis in this wave.
Liu Sheng didn't understand, but he was very excited and couldn't help saying: "In this way, the number of people can be reduced a lot."
"It's just that the first wave is these. If we don't win, the number will increase." Jiang Yuan can't guarantee that the murderer must not have the ability to counter-reconnaissance, or that he will counter-reconnaissance by coincidence.
It's just that the current investigation scale is still small, and it can't arouse Jiang Yuan's nervousness.
A little late, meow meow~
