Restarting life by going to the countryside to support medical work

Chapter 461 Clues

Su Xiaomin carefully observed the window with the protective net cut off on the west side of the office building for a while.

Apart from a few threads of the glove left on the cut steel bar, there were no other traces.

"Director Su, this cut steel bar seems to be deliberately creating confusion."

"How to say?"

"Look, there are no scratches on the windowsill inside the window, and the dust on the windowsill doesn't show any signs of being scratched." In order to let Su Xiaomin see more clearly, the investigator turned on the flashlight, shone it on the windowsill from the side, and pointed at the floating dust on it and said.

Su Xiaomin half squatted down and observed carefully for a while, then nodded in agreement.

Only one of the steel bars was cut off, and the gap was not big. It was almost impossible for a normal adult man to get through the gap.

But even if a child or a thin woman could squeeze in through this gap, they would definitely rub against the windowsill inside in the process.

Not to mention a person, even a cat would hit the windowsill first after getting in through this gap.

Now the dust on the windowsill shows no signs of being damaged, and no traces are left. It is obvious that although the steel bar was damaged, there are also marks left when it was folded up.

However, considering that there were no traces left on the windowsill, the perpetrator cut the steel bar but did not enter from here.

Why didn't you enter?
There wasn't enough of a gap, his shoulders were too broad to fit through there.

Why didn’t he cut another one? If he could cut one, it meant he had the right tool, and if he could cut one, he could cut the second one.

The reason for not cutting the second one is because there was not enough time?

Do not!
Su Xiaomin quickly rejected this idea.

After cutting the first steel bar, the perpetrator folded it up with great effort, and then folded it back to try to restore it to its original shape. This steel bar was as thick as a thumb, so it was not easy to fold it up or bend it back.

If he had time to restore it, how could he not have time to cut the second one? It was definitely not because he didn't have enough time.

It seems that the purpose of the perpetrator doing this may be to create confusion.

Why do we have to create confusion?
He wanted the investigators to believe that the person who stole the important document stored in the confidential room came in from outside.

Doesn't this indirectly reflect that the person who actually stole the important information was actually in the office building before stealing it?

Thinking of this, Su Xiaomin, who was standing outside the building, looked through the window into the corridor where the light was still dim even with the lights on.

Now, except for the people he brought with him and Sun Jian'an, the security chief of the Iron and Steel Research Institute, everyone else, including the leaders of Beijing Iron and Steel General Plant, were holding a meeting in the large conference room with the representatives of the subordinate unit of the army who had rushed over.

It's called a meeting, but in fact it's just waiting.

After looking at the dim corridor for a few seconds, Su Xiaomin turned to look at Sun Jianan who was standing next to him.

"Are you the head of security at the Steel Research Institute?"

"Yes, Director Su, my name is Sun Jian."

"Where were you tonight?"

"Reporting to Director Su, I am on duty tonight. I have been at the office since I got off work at six o'clock and have not gone out..."

At this point, Sun Jianan paused and then changed his words, "I was wrong. I went out once. It was when I found that the protective net and the wire mesh on the wall were damaged. I asked to notify Director Sun of our factory security department to come over, but he was not at home, so I rode my tricycle out to find Director Sun."

"You didn't go out until you found out what happened?"

"I didn't go out. I just stood at the gate for a while when the movie was over."

"The movie is over? What movie is over?"

"Oh, our main factory has reserved the Workers' Club across the street and organized all the cadres and employees to watch a movie. Tonight we are watching it at the Institute. It starts at 8 o'clock and will probably end around 9:30."

While replying, Section Chief Sun kept wiping his forehead with a handkerchief.

"Is Section Chief Sun nervous?" Su Xiaomin asked casually when he saw his actions.

Sun Jianan said bitterly, "Director Su, such a big thing happened while I was on duty. How could I not be nervous? To be honest, my legs are still weak and I am shaking all the time."

Su Xiaomin glanced at Section Chief Sun's legs. His pants were a bit baggy and he couldn't tell whether his legs were shaking or not.

However, he could understand why Section Chief Sun was so nervous, so he did not continue the topic and asked him to lead the way to the theft site in the confidential room on the third floor.

"Director Su, please."

Hearing that Su Xiaomin wanted to go to the third floor to see the scene, Sun Jianan quickly stepped aside and stretched out his hand to guide him.

At the scene of the theft in the confidential room on the third floor, investigators from the three bureaus were already conducting an inspection, and the director of the confidential room, Chen Dayou, was also there.

When Su Xiaomin came up, Chen Dayou was squatting in the aisle outside the door of the confidential room that was installed in the corridor, his face looking dejected.

Since he became the director of the confidential office, he has paid great attention to the safekeeping of important information and has always been extremely careful for fear of any problems arising.

But unexpectedly, despite all the precautions, something went wrong, and the document lost was very important.

Actually, if you really think about it, this matter has little to do with him.

As long as he didn't steal it, and he did his job well, then if the information is lost, the Security Department should be held most responsible. After all, the security of the building after get off work is the responsibility of the Security Department.

It is not certain whether he stole it or not, and we will have to investigate to find out.

Hearing the footsteps behind him, Chen Dayou, who had been squatting there looking at the door, turned around and saw that it was the deputy director who came to investigate the case. He quickly stood up. Before he could say anything, a man came out of the door, bringing people to check the traces left at the scene.

As soon as he came out, he saluted Su Xiaomin.

"Deputy Director Su..."

"Mingtang, tell me about the situation here."

The lost information was very important. When the notice was received, the superiors demanded that the case be solved as soon as possible and the information must not be leaked. Therefore, Su Xiaomin did not say anything and directly asked for an on-site report.

"Yes, Deputy Director Su, based on the traces left at the scene, we can preliminarily determine that the first door and the door to the data room inside were opened with a key. We did not find any signs of picking the lock."

After hearing this, Su Xiaomin raised his eyebrows in surprise and turned to look at Chen Dayou, director of the confidential office.

This is why Chen Dayou looked so pale.

Only he and the security guard in the data custodian's room had the keys to the two locks of the first door. They were the ones who opened and closed the door together every day. Not to mention the door inside, the outer door was opened by the criminals with the key. This was enough for him to explain.

"Director Chen, who has the key to this door?"

Su Xiaomin reached out and grabbed the door, bent down and looked carefully at the two locks on the door. Investigator Mingtang turned on the flashlight in his hand and shone it on the locks so that he could see more clearly.

While looking at the lock carefully, Su Xiaomin asked.

"The key to the upper lock is with me, and the key to the lower lock is in the hands of the security guard in the data custodian's room."

"Deputy Director Su, Fang Baoan has been temporarily taken into custody. He is in this room. Two of our men are accompanying him inside."

Mingtang raised his hand and pointed outside the first door, which was the deputy director's office two offices away from this side.

Su Xiaomin nodded without comment.

The security department of the Iron and Steel Research Institute did one thing well. After discovering that the steel bars of the west window on the first floor had been cut, no one was allowed to leave the office building.

Now the sentries downstairs and in the courtyard have been taken over by the people he brought. Tonight, every cadre and employee of the Steel Research Institute in this building, including those at home, must hand in a statement of their whereabouts tonight. There must be two or more witnesses, who cannot be relatives, and they cannot verify each other.

Except for the leaders of the general factory, everyone else in the conference room is writing. Several cadres from the general factory and investigators from the Third Bureau have gone to the family quarters to look for other employees of the Steel Research Institute.

Fortunately, most of these people live in the Beijing Iron and Steel Family Compound, which makes it easier to control and find them.

"Director Chen, where are your keys?" "Director Chen's keys are with me, and the security guard's keys to that room have also been given to me." Without waiting for Chen Dayou to speak, Investigator Mingtang spoke up to explain.

"Does the door to the data room inside also use a key?"

"As with this door, we found no signs of having been forced upon the lock of the inner door."

"Well, each lock should have three keys, one that is often used, and the remaining two keys as spares?"

"The spare keys are kept in the confidential department of Beijing Iron and Steel General Factory. Director Yang of the General Factory has just called the director of the confidential department and asked her to bring the spare keys over. Our people have gone to pick up Director Wang and will accompany her to get the keys first and then come over."

"it is good"

Su Xiaomin nodded, walked into the first door, but as soon as he entered, he stopped again, turned around and said to Chen Dayou.

"Director Chen, don't hang around here anymore. Go to that office first and write down your whereabouts tonight. We'll talk about it after we've reviewed it."

"Uh...Okay, okay, I'll go right away." Chen Dayou nodded hurriedly, and accompanied by another investigator from the Third Bureau, he walked to the door of the security guard's office of the temporary custody room and knocked.

After the door was opened, the investigator outside spoke to the people in the room, watched Chen Dayou go in, and after the door was closed again, he returned to stand outside the first door.

Sun Jianan, the head of the Security Department of the Iron and Steel Research Institute, was also standing outside the door. He did not dare to go in on his own initiative unless he was asked to enter the first door.

Inside the first door, the doors of several offices had been opened, and the investigators who had arrived earlier were busy in the room with the sign "Data Room" on it.

Su Xiaomin walked to the door and stopped. He bent down and looked carefully at the lock on the door. Mingtang turned on the flashlight again, mainly shining it on the keyhole.

If you pick the lock, whether you use tools or the so-called master key, it will leave scratches in the lock core. Without disassembling the lock core, you can still see some traces if you observe carefully.

The door lock of the data room is the same as the door lock of the first door, and there is no unusual mark left on it. In this case, it is usually opened with a matching key.

There is also another situation that may cause the current situation, that is, someone uses the original key of the lock to make a new key, and this new key is not the first time to open the lock.

Because if it is a new key that is installed later, if it is the first time to open the lock, some traces will be left.

call……

After looking at the lock for a while, Su Xiaomin straightened up and let out a long breath, then pointed inside the house and asked, "Did you find any suspicious footprints or fingerprints in the house?"

"No." Mingtang pouted and shook his head. He squatted down and shone the flashlight on the floor inside the house.

"I just asked Chen Dayou. Every afternoon after get off work, the people in their confidential office would mop the floor before leaving. You see, the floor is very clean."

Following Mingtang's words, Su Xiaomin also squatted down and looked carefully at the floor inside the house illuminated by the flashlight.

Although it was a cement floor, there was indeed almost no dust. In this case, unless the perpetrator walked barefoot inside, it would be impossible for him to leave footprints.

"As for fingerprints... we did find a fingerprint in the file cabinet that contained the lost document, but there is no way to identify it. The perpetrator must have left it while wearing gloves."

Su Xiaomin clapped his hands and stood up, while shaking his head helplessly. It seemed that many criminals now choose to wear gloves when committing crimes to prevent leaving fingerprints.

This caused great inconvenience to their investigators.

"Is the filing cabinet usually locked or..."

“It’s locked. I just asked the security guard in the custodian’s room, and he said he locks the filing cabinet before leaving get off work every day, and checks it before leaving. It was locked today as well.

It was confirmed that he had locked the filing cabinet because the lock was broken.”

"It was pried open?" Su Xiaomin was slightly startled. "So the perpetrator only had the keys to the first door and the document room door."

"This should be."

"The doors of these offices..."

"None of them were opened. The perpetrator should have come directly to the data room. According to Chen Dayou, when he and Fang Baoan came here just now, the first door was locked. After they opened the door with the key, they found that the doors of these offices were also locked.

However, after the security guard opened the door of the data room and saw that the door of the filing cabinet was open, he hurried over to check and discovered that the important document was missing.

As for the other offices, nothing was found missing and no one was found to have entered.

This reflects a problem from the side, that is, the perpetrator knew that the important information he wanted to steal was kept in the data room. "

Hearing this, Su Xiaomin turned around and looked at the office opposite the document room.

The door of this office is also open. At a glance, you can see an office desk inside. There are also sofas and coffee tables near the door. This is the director's office, that is, Chen Dayou's office.

Just as he was about to look away, Su Xiaomin suddenly saw something in the office and couldn't help but say "hmm".

He raised his hand and pointed to the director's office and asked, "Is that the safe?"

The sofa in the director's office is placed against the wall near the door. Behind the sofa is an iron filing cabinet, and beyond that is a green low cabinet that looks like a safe.

When Su Xiaomin looked towards the director's office, Mingtang's gaze also shifted here. In response to the question, he nodded.

"Yes, that is a safe."

"What's in the safe? If the information is so important, why isn't it in a safe, but in this ordinary filing cabinet with almost no protection?"

"This..." Mingtang hesitated for a moment before answering honestly: "Deputy Director Su, I didn't ask Chen Dayou this question."

"Did he open the safe just now?"

"He hasn't opened it since we got here. He said nothing is missing from his office. He must have checked it before we came."

"Remember, ask him later to open the safe and see what's inside that's more important than that document."

"Yes"

"Okay, if you can't find any more traces, then we'll pack up. You take your men to talk to the security guards on duty tonight. I'll go to the conference room to meet with the leaders of Beijing Iron and Steel General Plant and the Steel Research Institute."

"Ok"

After taking another look at the several offices in the confidential room, Su Xiaomin walked towards the first door. After going out, he waved to Sun Jianan from the security department who had been standing outside to follow him.

"Chief Sun, I heard that your security department has arranged two guards in front of the office building, right?"

"Yes, Chief Su."

“Is it possible for them to enter the office building on their own?”

"Uh...it's possible. The toilet for the sentry is the first one on the right after you enter the first floor."

"What about the others? Where do the others go to the bathroom?"

"There is a toilet next to our duty room at the main gate, and there is also one in the backyard. Under normal circumstances, except for those who are on guard in front of the office building, no one else will choose to go to the toilet in the office building.

Oh, and the three people who come to patrol the office building every hour may also use the toilet here."

"Does the person on guard have a registration book in his hand? All people entering and leaving the office building must register?"

“Yes, but not every time you enter, you register.”

"What do you mean? I heard that you have to register when you come in and out."

"Director Su, that's for outsiders. Those who work in the building register once when they come to work in the morning and once when they leave work in the afternoon. Each registration only records the time."

"Oh, I understand what you mean. When you come to work in the morning, before entering the office building, you first register your coming-to-work time at the sentry post. When you leave work in the afternoon, you register your coming-to-get off work time again. As for entering and leaving during work hours, you don't register, right?"

"Yes, outsiders will register their names, work units, and entry and exit times. If they are from Jinggang, we will just check their work ID. If they are from outside the company, we will also check their letters of introduction. If they don't have letters of introduction, we will then ask whoever they are looking for to meet them."

"Yeah" Hearing this, Su Xiaomin nodded and continued asking.
