The four social elites are all about the same age, and their income and social status are not low.
Why would these four people kill a few college students who had just graduated from college or who had not yet graduated?
Especially since the situations are still highly similar. They don't know each other at all, and neither of them admits that they killed each other.
Xu Lin looked at the interrogation record played in front of him, tapped the table gently, and showed a thoughtful expression.
This reminded him of a case, the revenge murder case of Jiang Zhenbin and his wife.
The deceased appeared to have no relevant connections.
After a moment, he stood up and said: "Give me a copy of the investigation of the deceased's social relations, the investigation of the murderer's social relations and all the interrogation records."
After hearing his words, Zhu Yan and the other three were slightly stunned.
Then Ji Chen nodded and said, "Okay, I'll get it for you right now."
After a while, he handed all the confessions and information to Xu Lin, and he turned around and handed them to the members of the special case team, asking them to analyze every word thoroughly.
Especially the first interrogation of the murderer, the second interrogation, and the third interrogation, compare and analyze every word the murderer said.
The second point is to find what the victims have in common, which is one of the most important ideas in handling cases.
Xu Lin himself came to the forensic department with Zhu Yan and the others.
In the forensic department, Fang Qingying is already working.
He carefully conducted a comprehensive examination of the bodies of the five deceased people and found that the cause of death was indeed a sharp knife piercing the heart, causing massive hemorrhage.
But the strangest thing is that there is no pain on the face of each deceased person when they die.
They looked calm, and even said they were facing death calmly. Two of them still had smiles on their faces before they died.
Fang Qingying was puzzled by this point.
At the same time, she carefully tested the murder weapons used by the five murderers and confirmed that they were consistent with the wounds, and the fingerprints on the murder weapons also belonged to the murderers.
Not only that, there were footprints left by the murderer at the scene, and one murderer seemed to have been so excited that he cut his finger, leaving blood stains on the door frame, which meant DNA was left behind.
All these indeed prove that the person arrested is the murderer. ,
Xu Lin also believed that these four people were the murderers.
But here comes the problem. The Eye of Good and Evil determines that their crime value is very low, and they say that they did not kill anyone.
So long an explanation might make sense.
These four people were not conscious when they killed, and they even had no idea what they were doing?
Sleepwalking?
Or hypnosis?
Thinking of these two terms, Xu Lin's heart suddenly moved.
He came to one of the deceased and looked at the calm expression on the deceased's face, his eyes twinkling.
Five people, two of them were still smiling before they died.
Don't they feel the pain?
No! impossible!
How could you not feel the pain when a sharp knife was stabbed into your chest?
Unless they were under general anesthesia at the moment, the Fengyang City Bureau's forensic doctor conducted a detailed examination after the incident and confirmed that there were no toxins or drugs left in the deceased's body.
That is, they were not anesthetized.
But Xu Lin believed that they were anesthetized, and mental anesthesia was also a kind of anesthesia.
Brainwashing or hypnosis?
Anyone who can do this must be a psychological master who knows how to manipulate people's hearts.
To be honest, Xu Lin doesn't really believe in such things as psychological masters and hypnosis.
The so-called hypnosis is nothing more than inducing people to enter a sleep state.
In this state, it is impossible for people to do some unconscious things, or even instigate murder. It is a fantasy.
But then again, this case itself is weird.
It is indeed very challenging for Xu Lin and the special case team.
"Xiao Fang, you must test me carefully and don't let go of any trace." Xu Lin said.
"Yes, team leader." Fang Qingying nodded and continued working.
Xu Lin inspected the corpse and activated the Corpse Whisperer skill. Although many details could be seen, Fang Qingying was as meticulous as his hair and had taken almost all the details into consideration.
After some inspections, he found nothing, so he left the forensic department and returned to the criminal investigation detachment.
Here at the Criminal Investigation Detachment, the members of the Special Case Team, together with Zhu Yan, Dang Lin, and Ji Chen, watched the interrogation records over and over again, looking for clues from every word.
Although this method is very stupid, we are all experienced criminal investigators and understand that clues are often found from these files and interrogation videos.
Breakthroughs are often hidden in inconspicuous places, perhaps just a sentence or a text.
But they looked at it three times and still couldn't find any problems.
The social relationships of the deceased, the confessions of family members, etc. basically show that they had no intersection.
Police officers from the technical team came over and logged into some of their social networking accounts. Based on their usual chat records, they found nothing of value.
The only valuable thing may be that the five deceased people usually like to buy some daily necessities, but now that the Internet era is extremely developed, this situation is normal.
The same is true for the murderer.
4 murderers, no intersection exists.
Even when they checked the files of the four murderers from 10 years ago, they couldn't find anything.
The case reached a dead end for a while.
When Xu Lin arrived at the criminal investigation detachment, he saw a group of people still watching the surveillance video of the interrogation attentively.
He also made a copy, and then asked a fellow detective to find a computer and read it.
The interrogations of Tang Huashan, Ren Danian, Ge Zhen, and Zhang Qi were repeated over and over again.
They were interrogated four times in total, including the one he just interrogated and the three previous interrogations by Zhu Yan and the others.
What Xu Lin mainly looked at was the three times he was interrogated by them.
During the first interrogation, the four murderers were at a loss. When they talked about their murders, their emotions fluctuated greatly, with a look of horror in their eyes.
They argued hard, but when the police showed the video evidence, their faces turned pale.
By the end, they showed their despair.
They began to defend themselves, but in the face of absolute irrefutable evidence, there was no way they could do it.
The interrogation finally stopped until the four people were almost driven crazy.
Xu Lin looked at the surveillance on the computer screen and frowned deeply.
"how so?"
"its not right!"
He touched his chin with a surprised look on his face.
It seems that I have found a doubt that has been ignored.
