When Xu Lin heard Wu Xiaofeng's return, his expression immediately became extremely solemn.
The murderer's planning may have taken longer than he thought.
It actually opened up the school and the warehouse of the cotton spinning factory. There is definitely a big problem here.
"Check, except for the 31 children, dig up the identities of all the other people who were burned to death. The murderer should be among these eight people."
Xu Lin gritted his teeth and gave the order directly.
He believed in his own judgment. If the murderer was not inside, the underground passage would have no meaning.
If the murderer was not inside, then he would not have had time to commit the crime.
The dossier makes it clear that although the warehouse of the cotton spinning factory is filled with flammable items such as cotton batting, cloth, cartons and foam, there is no combustion aid and it is impossible for it to burn for no reason.
And once it burns, the fire will definitely reach the sky within 5 minutes.
At that time, there were surveillance systems inside both schools and cotton spinning factories, and people would find out if they came out.
Another thing is that there is one missing computer on site.
The surveillance footage at that time was temporarily blurred due to the fire. If Xu Lin guessed correctly, the murderer had already left when the problem occurred.
That computer was one of the murderer's tools.
Xu Lin has almost repeated the entire arson case in his mind.
The murderer took control of the group of students, teachers, and people in the warehouse in advance, and then carried out arson. After setting the warehouse on fire, he hid underground for two more days.
He used his computer to destroy a piece of surveillance that was taken when he left after the fire.
Although there is no way to verify this, if it were him, he would do this. Only in this way can the arsonist disappear silently.
The quilts in the underground passages are used to insulate the heat of the fire, because if a fire breaks out above and the high temperature pours in, even underground, they may be roasted to death.
Use a damp quilt to isolate yourself from high temperatures.
Once he leaves, everything will be fine.
Because... he is already a dead man, and no one can doubt him anymore.
After receiving the order, Wu Xiaofeng and the others immediately began to investigate the eight people who were burned to death.
Although this will inevitably encounter resistance from the family members, for the sake of the case, they have no choice. No matter how bad the family members' attitude is, they can only patiently persuade them.
Xu Lin also took charge of a person, a cotton spinning factory employee named Zheng Xin.
There is no one in Zheng Xin's family. His parents died young and he is the only one left.
And because they were immigrants who settled in Nanlin City, they were not very familiar with the neighbors, so everyone knew very little about their family.
Later, Zheng Xin's home was temporarily used as a warehouse by the neighborhood committee, and it lasted seven or eight years.
An aunt named Li from the neighborhood committee took Xu Lin into Zheng Xin's home.
Seeing the clutter in the room, Xu Lin frowned.
"That... little comrade, we have cleaned up most of the things here. You see, your investigation here is in vain. Besides, his family is also a victim, you should go find the murderer!"
Aunt Li said.
Xu Lin: "You also know that they are victims, so since they are victims, why do you want to occupy their house? You are limited to move out all your belongings within one day. This house, our city bureau Use it."
Aunt Li's face turned red and white when she was told that, but she just smiled and did not dare to argue.
This matter itself is because their neighborhood committee did something unreasonable.
Xu Lin left Zheng Xin's home. The place was full of debris, and Zheng Xin's things had been moved away. There was really no point in digging anymore.
But there isn't one here, there should be one in his hometown.
Xu Lin found the local police station, revealed his identity, and asked to trace the original residence registration location of Zheng Xin's family.
"Beiyuan Province, Shihezigou, Maojia Town, Fengyu City..."
Boy, this place is really far away!
He couldn't help but shook his head. It was almost 2,000 kilometers away, and this trip had not been possible for half a month.
Let’s leave it alone for now and check on a few other people.
The intense verification work continued, and Wei Mingfei was arranged by Xu Lin to stay in a hotel opposite the city bureau.
In any case, even if Xu Lin knew that he was innocent, under such circumstances, he still couldn't run around, let alone disappear, otherwise it would be really unclear.
Because in this world, it was Xu Lin who found him innocent.
Soon, Wu Xiaofeng, Han Xing, and Xiao Xue returned with thick investigation reports and confession records.
They investigated for two full days and visited all the victims except Zheng Xin. The results they obtained were similar to those of the previous investigation.
Moreover, these households are basically all local. Even if two of them are from other places, that is, in the surrounding provinces and cities, the three of them have checked and they have no problems at all.
Xu Linzi carefully read all the information they got back, and finally confirmed that there was indeed no problem.
So in the end, there is only one Zheng Xin left.
Although all three members of their family are dead, there must be relatives in their hometown, right?
As long as you have relatives, you can trace your origins.
Then Xu Lin's team of four took Wei Mingfei and headed north directly to Beiyuan Province.
After flying for 4 hours, they finally arrived at Zheng Xin's original place of residence.
When they came to the local police station to learn about the situation when Zheng Xin's family moved out, a policeman in his 50s stated the situation to Xu Lin and others.
"The Zheng family in Shihezigou is an honest and responsible family. They are very popular in the town, especially the Zheng family brothers. Everyone in the village will give them a thumbs up when they meet them. The two half-sized brothers son……"
boom!
Xu Lin felt as if his head was exploding. He grabbed the policeman and asked, "Teacher, what did you just say? Two brothers, two half-grown men?"
"Aren't they just half-grown men? The twin brothers, the only twins in Shihezigou at that time, were from the Zheng family. Everyone said that the Zheng family's blessings were good, they were popular, and God was keeping a close eye on them..."
Xu Lin's expression became solemn, and he raised his head and looked at the four people beside him.
This case has almost come to light.
Others don't have problems, but Zheng Xin has problems.
So this Zheng Xin, what name does he use now?
Xu Lin asked: "Master, where are the Zheng brothers now?"
"I don't know about the second child, but I heard that the eldest son went out to work many years ago, and later he took all three of their family back. No, a few years ago, their eldest son came back once, and gave it to the big guy We’ve all given away rice, flour, grain and oil!”
"A few years ago? How long, how long ago?" Wu Xiaofeng asked eagerly.
"Four years ago, right? It should be four years ago." The old policeman said with memories.
