Chapter 749 Blind spots change experience (more)
Q city, airport.
On the driveway outside the runway, there was already a row of convoys parked.
A man in a black mountain suit uniform stood outside the vehicle.
Facing the civil aviation passenger plane slowly descending from the sky, pay attention to the salute.
When Xiao Yu and Wang Dong got off the plane, they walked to the convoy.
The members of the second group raised their hands in unison and saluted.
Xiao Yu returned the salute, everyone got on the car, and the team left.
This scene.
It attracted the attention of passengers who got off the plane not far away.
Countless people looked at the Yuanqu convoy in amazement, and began to make up their minds...
The convoy drove all the way to the Q City National Security Bureau.
Every provincial capital city will have this kind of special permanent establishment.
It was another welcome, but the scene was not big, and the level was very high.
Wang Dong knew the little brother's character, and didn't like these so-called cards.
That's why I told you not to do such silly things and be careful with your ass.
If Xiao Yu gets angry, the big boss will have a headache.
meeting room.
There are no 'outsiders'.
Only Xiao Yu and the second group of people.
His eyes were fixed on the curtain on the wall, looking at the projection light curtain.
Look at the most detailed on-site investigation and case files of this case.
"The twelve victims are all smart device enthusiasts, and the murder scene is basically a residence with a large number of smart home appliances."
"Through on-site investigation, we found that these victims' homes had smart voice master control devices that could control most of the smart home appliances in the room. For example, smart door locks, smart air conditioners, smart heaters, smart pressure cookers, smart distribution boxes... Wait."
"The causes of death of the 12 victims were four cases of heater leakage and electric shock, two cases of air-conditioning poisonous gas, two cases of pressure cooker explosion, two cases of humidifier, one case of spontaneous combustion of TV set, and one case of electric leakage of washing machine."
"The twelve victims were all killed in different cities, so they looked like accidental deaths, but through various signs and on-site inspections by our personnel, it can be confirmed that they were all caused by man."
"The reason for this is so clear, because the twelve victims are all single, female, and all the air conditioners in the house are turned on. Except for one person who caused a fire caused by the TV, his body was burned. The bodies of the other eleven victims were found. Highly rotten state."
"It can be said that the twelve victims were all killed by the murderer's smart device."
"However, through the cooperation of computer and smart device technicians dispatched by our side to cooperate with the investigation, it was found that the smart devices in the homes of the twelve victims had no trace of human intrusion at all, and all of them were in a 'quasi-normal' state."
"So...we can't find any clues left by the murderer!"
A member of the second team looked bitter, and looked at Xiao Yu who was sitting on the chair in front of him, squinting at the projected light curtain, "Boss, that's all we have investigated."
"Thanks for your hard work."
Xiao Yu smiled, "Just do your best."
Everyone present, including Wang Dong, was ashamed.
They will not find any excuses such as 'the time is too short', 'the case is suspenseful', and 'difficult to investigate across provinces and cities'.
No trace clues were found, just not found.
We are all human beings, and human beings will have blind spots in knowledge.
Even Xiao Yu has areas that he is not good at and does not know.
But you can learn, get in touch, and understand.
In the end it becomes your own experience.
Why is the old criminal investigator awesome?
Because of the rich experience!
"go to the scene."
Xiao Yu got up and walked outside.
Why is Q City the first stop?
Because this is the only victim city where the surveillance video is kept.
That is, the video of the murdered woman that Xiao Yu watched.
Xiao Yu can't believe the investigation ability of the second group?
no.
Going to the scene is not necessarily looking for clues, it can also be looking for 'abnormalities'.
Some cases have flaws, not necessarily on the most conspicuous clues and traces.
But on some various 'abnormalities'.
Abnormal is abnormal, different from usual.
Xiao Yu likes to say the phrase 'if something goes wrong, there must be a demon'.
Abnormal, that's what it means!
...
Walk into a community and walk into the residential building where the victim lives.
"Song Ni, female, aged, from City Q, single, manager of a private company, monthly salary 20,000, self-purchased property, living alone..."
In the elevator, Wang Dong had a serious expression. "According to the time, she is the eleventh victim. The body was born sixteen days ago. Her best friend called the police because she couldn't find anyone."
"However, the police had arrived at the scene half a day earlier. The reason was that the corpse was highly decomposed and had a stench. Residents in the same building went to the property. The property confirmed that the smell came from the victim, Song Ni, and called the police."
The elevator door opened, but Xiao Yu didn't speak.
His brain was thinking, remembering the content of the video he had watched.
I still remember that after the victim Song Ni returned home, she called her best friend, went out to eat, and returned home drunk.
Afterwards, a smart device 'killing' accident occurred.
Are you suspicious?
Why did Xiao Yu suspect this girlfriend?
occupational disease.
Because the police will habitually list the caller as a suspect when handling cases.
why?
Because in this world, there are always cases where the police call the police.
More than 4% of the people who called the police were murderers.
Out of a hundred people calling the police, more than four were perpetrators.
Do you still think the probability is low?
So why do people like them call the police?
Deception, self-deception psychology.
First, they wanted to deceive others and confuse the police's scope of investigation.
Second, the special identity of the person who wants to take advantage of the opportunity to make up for the important plot of the case in the later stage, so as to delay the police's detection.
Because it is the person who called the police, the testimony is more critical, and most of them will be adopted by the police.
It is also extremely easy to cause the case to develop in the correct direction.
The point is, if you know that the police have any correct inferences, you can still run away!
"Have you checked?"
Standing outside a door that was opened and guarded by two team members, Xiao Yu took the disposable shoe covers from the team members and put them on the leather shoes.
Wang Dong is also an old criminal investigator.
Xiao Yu didn't think he would make such a low-level mistake.
"Definitely checked."
Wang Dong, who was wearing shoe covers, rolled his eyes and shook his head, "Nothing unusual."
"Ok."
Xiao Yu nodded and walked into the scene of the victim's case.
The increased sense of smell of Wang Die's nose also made him immediately smell a corpse.
Xiao Yu didn't look at the bathroom where the victim died, but looked at the hall.
The line of sight fell on some home appliances...
