Chapter 101 Footprints under the Bed
No one has been here for a few days, and there is a little dust accumulated on the ground.
Fortunately, the time was short and had no impact on the traces on the ground. There were many messy footprints in the corridor. It was discovered that several people had come in after Lu Dawang's death.
After Xu Zhanjie arrived, he immediately ordered that no one else be allowed to enter, otherwise the ground would be even more chaotic.
Holding the camera, Xu Qingyun kept taking pictures.
Each footprint must be photographed clearly. Even if it is destroyed and only half of it remains, or even a smaller shoe print, a lot can still be seen.
After filming in the corridor, Xu Qingyun entered the dormitory alone.
The body was long gone, and the things inside were all arranged as they were when Lu Dawang died. There were many footprints on the ground, and Xu Qingyun took pictures one by one.
Except for the ground, all other locations need to be looked at.
Xu Qingyun did not miss any detail including tables, beds, benches, wardrobes, washbasin stands, table lamps, sinks, even thermos bottles, lamp cords, etc.
Lu Dawang’s personal belongings are in the dormitory, including his shoes.
After taking pictures of everything, Xu Qingyun asked Yan Ming and others to come in.
When they go in, they also wear shoe covers and gloves to avoid damaging the scene.
Jason Xiang accompanied them and stood inside without moving.
He came here to see it and found nothing.
"Yan Ming, search under the bed and on the wall. Fang Laibao, look at the roof and the cracks in the wall. Pay attention to whether there is anything missing."
Xu Qingyun ordered that everything in the room must be carefully inspected. He asked them to come over just to help them look together. It would be a waste of time for him to look at many places alone.
Both Yan Ming and Fang Laibao are careful people, so there is no problem in leaving it to them.
"Yes, team leader."
The two of them took orders together and did their own division of labor.
"Team leader Xiang, has the poison been found out?"
"It was found to be arsenic."
Xiang Jason hurriedly replied that arsenic has been around since ancient times and is one of the most common poisons.
"Is there an autopsy? What did he eat?" Xu Qingyun continued to ask.
"There is an autopsy, and they ate sesame seed cakes and pig head meat. I'm checking the source of the food."
After the autopsy, Xiang Jason launched an investigation into the source of the food. Shaobing and pig head meat were common foods. Lu Dawang ate them all without leaving any food residue. The investigation was not easy.
"How pure is the arsenic?" Xu Qingyun suddenly asked.
"purity?"
Jason Xiang was stunned for a moment. He only knew that it was arsenic poisoning. He really didn't know the purity of the arsenic.
"Find me the autopsy doctor and I'll ask him."
Seeing that Xiang Jiesheng didn't know anything, Xu Qingyun didn't say much. The food was ordinary and the poison was common. It seemed like he was planning to poison him.
Lu Dawang could eat poisonous food with confidence, either because he had been targeted for a long time, or because it was given by someone who was familiar with him.
All investigation directions must be verified.
"good."
Nodding to Jason, Xu Qingyun handled the case differently than others. Unexpectedly, he came up and asked a question he didn't know.
Arsenic existed in ancient times and was used in many applications in ancient China. Many historical figures died from this poison.
Arsenic is a colorless and odorless white powder. It produces a garlic smell when heated. However, the ancient arsenic extraction technology is immature and contains many impurities that produce sulfide.
Sulfide reacts chemically with silver to form silver sulfide.
Silver sulfide has a color, gray and black, so in ancient times, silver needles were used to detect poisons. The silver needle was inserted into the food. Once it turned black, it indicated that arsenic was contained in it.
Xiang Jason didn't understand this, so Xu Qingyun stopped asking him.
"Team leader, come here."
Yan Ming suddenly shouted, and Xu Qingyun immediately walked over. Yan Ming was searching under the bed, walls and other places in Lu Dawang's room.
This is a dormitory, so the possibility of hidden compartments is very low, but we have to check.
Xiang Jason hurriedly followed.
"Look."
Yan Ming had pulled out the bed and pointed to the wall under the head of the bed. There were marks on it where his feet had been pushed.
Xu Qingyun narrowed his eyes and immediately took out his camera to take pictures.
Jason Xiang was stunned for a moment, then returned to normal.
If they had inspected carefully, they could have found this trace, but after the section chief found out that the person was dead, he immediately blocked the scene and did not allow them to inspect it carefully.
This is not a work error on their part, and Xiang Jason has nothing to worry about.
"Team leader, there is a situation here."
Fang Laibao suddenly shouted. He stepped on the chair and was checking the wall cracks on the cabinet, and found something different behind the cabinet.
"Move the cabinet out first."
Xu Qingyun ordered that it would be inconvenient for so many people to climb up together.
Carefully remove the cabinet. On the back and top of the cabinet, there is an area that is obviously different from the others.
Jason Xiang was stunned again. If they had known there were so many clues in the room, they should have insisted on searching instead of sealing it off.
"Scrape it off and send it for testing."
Xu Qingyun didn't touch it. Judging from the surface, it was obvious that something had stuck to it, and now the thing is no longer there.
Fang Laibao carefully scraped it off and restored the cabinet to its original position.
After carefully inspecting everything inside and out, Xu Qingyun took the people away.
The fourth intelligence team has not yet been formally established, but the Virgo has approved it.
Xu Zhanjie's reason was good. Xu Qingyun was the intelligence team leader at Tianjin Station. This time he was asked to lead the traitor case. It was inappropriate to give him the position of deputy team leader in other teams.
Xu Qingyun has enough merits to be the team leader.
In this case, set up a new group for him.
The members of the fourth intelligence team are not in place, but the offices have been vacated for them, with two separate offices and three large offices.
The fourth intelligence team arrived late, giving them the first floor that no one wanted to use.
This time was different from later generations, where people were lazy and unwilling to climb stairs. As long as the first floor was not damp and could provide access to the courtyard, it was more popular than the second and third floors with stairs.
At this time, the first floor will be somewhat damp.
Moreover, the higher the floor, the better the view. The scenery outside the window looks much more beautiful than that on the first floor, which can make people feel better.
Xu Qingyun doesn't care about the office environment, as long as it exists.
The first floor is more convenient for him.
A separate office belongs to him, and three large offices are dedicated to the three teams.
Now there are only three of them in the four groups in the Military Intelligence Office, and each of them has a spare room.
Fang Laibao sent the scraped things to the technical department for analysis, while Yan Ming helped Xu Qingyun expedite cleaning of the photos.
The office has not been tidied up yet, but it is very clean. Xu Qingyun doesn't care about these things, as long as he has a place to sit.
"Team Leader Xu."
There was a knock on the door, and Jason Xiang came in with a man.
The man wears glasses and looks elegant.
"Team leader Xiang, come in quickly."
"This is Dr. Li from the medical department. If you have any questions, you can ask him." Xiang Jason introduced that the headquarters has a specialized medical department with several professional doctors. Dr. Li has the highest technical level and is also used as a forensic doctor. .
"Hello, Dr. Li."
Xu Qingyun nodded. Dr. Li is a military doctor with the rank of lieutenant and is at the same level as Xu Qingyun.
He looked at the young man in front of him with a little curiosity. He had just heard from the team leader that the Intelligence Section had established a new four groups, and Xu Qingyun, the intelligence team leader of Tianjin Station, was transferred to serve.
He didn't expect Xu Qingyun to be so young.
"Team Leader Xu, you're welcome. I heard from the team leader that you want to ask about the purity of arsenic?"
Dr. Li sat up straight. He had heard of Xu Qingyun's name many times. The Tianjin Railway Station was the work of this young man who had made great contributions.
"That's right." Xu Qingyun nodded.
"We have tested arsenic before, but we did not do a purity test. If you want to know, I can try it, but we can't test the purity from the blood. We can only test it through the residue in the stomach, but because it has been placed for a few God, there’s no guarantee it can be completely detected.”
"It doesn't matter. It's best if you can detect it. If it doesn't work, forget it."
Xu Qingyun replied that the purity of arsenic is not very important, but it is a clue after all, so I asked.
"It's okay, do you have anything else to ask?"
Dr. Li has a very good attitude. He is a technician and has no real power, but he is a doctor and others respect him.
No one knows when he will ask Dr. Li to treat him. The doctor must not be easily offended.
"No, thank you for making a trip."
"It's okay, it should be."
Dr. Li got up and went back to prepare the test residue.
Xiang Jason didn't say anything. The section chief ordered that Xu Qingyun take full control of this case. He just wanted to see how Xu Qingyun investigated the case.
To be honest, this case is quite difficult.
Lu Dawang was dead. They knew nothing except that he had asked others about the case before. They had investigated Lu Dawang's interpersonal relationships and found nothing unusual.
Food is a clue, but difficult to investigate.
First of all, there are many sellers of sesame cakes and pork head meat.
There are at least hundreds of them in the city, and it is extremely difficult to find what you have already eaten in so many stores.
Secondly, what if we find out?
It's possible that the store owner didn't know anything about it and it was bought and poisoned by someone else, which is equivalent to the clue being cut off again.
As for the newly discovered footprints and sticky marks, they were also weak clues. If he wanted to use these things to identify the murderer or find out Lu Dawang's situation, Xiang Jason admitted that he couldn't do it.
Xu Qingyun's case in Tianjin is classified as confidential and has not been made public. Except for Yang Wenxu, no one else knows that Xu Qingyun has the ability to see footprints.
Yang Wenxu was the leader of the intelligence team. Xu Zhanjie had given him a confidentiality order, but he did not tell the public casually.
"Team Leader Xu, I'll go back to the office first. If you need anything, call me."
After Dr. Li left, Xiang Jason also left. Lu Dawang was his subordinate, and he had to cooperate with Xu Qingyun.
"To the team leader, I'll see you off."
Xu Qingyun didn't put on any airs. He had just arrived at the headquarters and needed to maintain good relationships with colleagues.
"Team leader, the technical department is already conducting tests and the results will be available tomorrow at the earliest. Is there anything you can do for me?"
Fang Laibao came back quickly. The technical department needed time, so he didn't wait there. He ran back to see if there was anything he could do.
The others are not here, and there are only three of them in the fourth group. They have not even appointed a team leader, and there is a lack of manpower around the team leader to help.
"Call all the people who have been to the scene except the team leader and section chief."
After thinking for a moment, Xu Qingyun said softly that the photo was still being developed, but he had already seen it and now he wanted to check the footprints at the scene.
Xu Qingyun had a hunch that the effect would not be too great, but the shoe prints on the wall under the bed were the most important clue.
Who would leave marks like that under the bed?
It was obvious that someone was hiding under Lu Dawang's bed. Lu Dawang's bed was a single bed, and when the sheets were laid down, they could indeed block the bottom.
This person should have rolled under the bed, with his feet facing the wall, but because there were no sheets at the end of the bed, he was afraid of being discovered, so he curled up as much as possible at the head of the bed, leaving footprints on the wall.
"Yes, I'll go right away."
Fang Laibao left happily, as long as he had something to do. This time it was a traitor case, and it was at the headquarters again.
If you do it well, it will definitely be a great achievement.
"Team leader, all the photos have been developed."
Yan Ming came to the office with the photo, Xu Qingyun took it and put it aside for the time being.
He took the photo, and you can tell how many shoe prints there are without looking at it.
Xu Zhanjie, Xiang Jiesheng, Yang Wenxu and others have them.
In addition, there are three people, and they are the ones Fang Laibao is looking for.
"Go and inquire about Lu Dawang's daily relationships, both inside and outside the station."
Xu Qingyun ordered that Lu Dawang was poisoned to death. The food was sesame cakes and pig head meat. These two things tasted really good together.
Adding some garlic juice can completely mask the smell of arsenic caused by heating.
There are two types of poisoners. One is a food vendor who sold the poisoned food to Lu Dawang and successfully poisoned him to death.
Secondly, someone gave Lu Dawang food, and Lu Dawang died after eating it.
If it's the latter, Lu Dawang must be someone with whom he has a good relationship.
Lu Dawang is from Zhejiang Province. His family conditions are not good and he only finished elementary school. Because of his good memory, he was noticed by the Military Intelligence Department and recruited him. After training in Hangzhou, he became a professional agent.
I was assigned to the Information Section just last year and have been working there for less than a year.
My usual performance is not outstanding, my relationship with my colleagues is average, my personality is boring, but my memory is really good and I can completely remember things I have read once.
Lu Dawang didn't have many acquaintances in Nanjing. He only had a good relationship with a few classmates from Hangzhou.
Dozens of people graduate from the intelligence major in Hangzhou every year. Not all of them are assigned to the headquarters, but to each branch. Xu Qingyun noticed that last year, a total of six students were assigned to the intelligence department, all in the intelligence department, with two students in each group. .
"Yes, team leader."
Yan Ming ran out and went to buy cigarettes first, good cigarettes.
This kid is the best at clichés. Even if he doesn't know people, he can call them brothers with just a few words and make people feel his sincerity.
It would be most appropriate for him to do this.
"Team leader, they are here."
Fang Laibao quickly brought three people to the office. One of them was Lu Dawang's roommate and was on the same team as Lu Dawang. He was the first to find out that Lu Dawang was dead.
He ran out to call someone, and someone came from the dormitory next door. Someone called their captain, and the captain went over with Jason Xiang and the others.
The three footprints on the ground were left by the roommate, the captain and another person who had gone in.
"Hello, Team Leader Xu."
The captain greeted him first. He was young, twenty-five years old. The Military Intelligence Department was established only a short time ago. Except for the station chief, section chief and others, most of them were young.
"I invited you here to ask you some questions. Don't be nervous. Come and sit here."
Xu Qingyun politely took them to the sofa. He just sprinkled some ashes on the ground. After a few people passed by, their footprints were immediately left on the ground.
It was indeed the three of them.
The number of people and footprints are correct.
The second update is guaranteed, and there will be an additional update at 12 o'clock.
