Chapter 25 Fenggang Family Planning is on fire, and the situation is carefully investigated

After officially going to work, the work is not very busy, and everyone is still in the state of the New Year; Coupled with the light rain that has been falling for several days, everyone is even more reluctant to go out.

Taking advantage of this effort, we will have dinner at Team Leader's house today, drink at Team Leader Ke's house tomorrow, or go to Team Zhang's house for tea.

However, this case waits for no one.

No, on the eighteenth day of the first month, there will be another case!

"Captain Li, I just received a call from the team leader of A'an in Fenggang Town, saying that there was a case in their town's family planning office, and it was a fire case! Ask us to survey the site. Xiao Ke said.

"Inform the driver and Xiao Cao, let's go and have a look together." As soon as I heard about the situation, I didn't think much about it and just arranged the work.

I got in touch with Team Leader A'an again.

"Hello, Team Leader A'an." As soon as the phone was connected, I would say hello first.

"It's okay for you, Captain Li, I'm afraid that this case needs you to run in person, this family planning office was set on fire, and Secretary Feng in the town attaches great importance to it, I heard that it has been reported to the county." Team leader A'an said.

"There's no problem with this, I'll ask a simple question and prepare." My voice.

"Captain Li, if there is any situation, you can ask directly." Aan said.

"Is the damage serious?" I asked directly.

"This is not very serious, but the family planning office was burned, and the surname is very bad, so I have to work hard for you." The voice of Team Leader A'an.

Brother, don't be afraid that I won't go, I thought to myself, but my mouth said:

"Did you inform the fire brigade then?"

"Notify the fire brigade?" Team Leader A'an asked.

"Yes, the fire brigade must be notified at the scene of this fire case, don't you know this?" I'm weird.

"Don't say it, I really don't know about this regulation, our police station has never had a fire case, the fire department is responsible for this firefighting, and the fire brigade has to investigate the scene of this fire case." It seems that Team Leader A'an really has no experience in this area, but fortunately I asked about the situation.

"The fire brigade has its own procedures in the scene investigation of the fire case, and in the closing of the case, there must be a report of the scene investigation." I popularize the basic knowledge of Team Leader A'an.

"Okay, I'll contact the fire brigade immediately, and you guys will come early, I'll wait for you." Team leader A'an hung up the phone after speaking.

After explaining the situation to Captain Zheng and Team Zhang, Team Zhang said:

"You go over and have a look first, and then contact us when you find out the situation, and we will decide how many people to send over according to the situation."

I nodded, and set off with Xiao Ke, Cao, and the driver.

In the car.

"Captain Li, have you seen the scene of a fire before?" Xiao Ke asked.

"Nope." My voice.

"Then how do you know that the fire brigade should be notified at the scene of a fire case?" It continues to be Xiao Ke's voice.

I smiled and said:

"There is Yan Ruyu in the book, and there is a golden house in the book!"

Several people laughed.

"Xiao Ke, have you investigated the fire scene before?" I asked rhetorically.

"I've seen it, I'm in charge of taking pictures. This kind of crime scene is basically investigated by Captain Zheng, where he told me to take pictures, I took pictures wherever he asked, I took pictures wherever he me, and followed him, basically without any care. Xiao Ke replied truthfully.

"Where's Cao?" I continued.

"I also followed Captain Zheng, even if I drew pictures or something, I didn't have any worries.

It appears that neither of these men had experience in surveying the scene of the fire.

So, I nodded, and said:

"Now let you investigate the scene of the fire, I don't worry, you can learn slowly. In the on-site investigation, you must be careful and meticulous, grasp every link, and never let go of any doubt. ”

The two men nodded earnestly.

"We have just some distance and time to Fenggang Town, so I will introduce you to the investigation of the fire case." I said, and each of them was given another cigarette.

The two of them smoked cigarettes and stared at me, and I slowly spoke:

"The process of the fire scene investigation is basically the same as that of our other cases, but it is different.

After the fire, all items are covered with a thick layer of soot, so it is generally difficult to extract fingerprints; At the same time, because a large amount of water was used in the room where the fire broke out during the rescue, it was difficult to extract the footprints.

We combined the location of the objects and equipment before the fire provided by the insider, as well as the fire source, power supply, indoor and outdoor scenes, etc., to determine the surname of the case.

It should be noted that it is necessary to find a route to enter the fire without destroying the scene, to patrol the fire ground, to find the final part of the fire spread, to investigate in the opposite direction of the fire spread from this part, to carefully observe the specific situation of the fire traces, to repeatedly observe the key parts and suspicious points, and to analyze and judge any traces left.

The main observations are as follows:

1. Focus on observing whether the doors and windows are damaged and the items are moved, and consider whether there is a possibility of arson at the scene;

2. Observe the burning of the same object or equipment from different directions, heights and parts;

3. Observe the location, direction and cause of the collapse, the smoke traces of walls and equipment, and the location and shape of the fire;

4. Deformation, distortion and melting of building structures and metal components;

5. Burning loss of electrical circuits and power equipment;

6. If there is an explosion or scattered objects;

7. Underground flammable and combustible gas and liquid pipelines and valves around the fire building.

With these observations, determine the location of the fire at the fire scene:

1. Identify the location of the fire according to the traces of spread. In the investigation of a building complex or a fire of a building, if the distance is close, the room between the rooms is generally spread through doors, corridors, stuffy roofs, and ventilation pipes; Between buildings, it is necessary to consider the ignition of flying fires, and the general situation is that the ignition point of the spreading building is lower than that of the burning building; Floor-to-floor sprawl generally spreads from bottom to top through stairs, windows, ventilation ducts, cables, pipe wells, and garbage chutes. According to the clues provided by the interviews with insiders, combined with the places where the fire had spread in the above-mentioned objects, the traces of spread were found, and which building, which floor, and which one started the fire were analyzed. Once the room where the fire started is located, the room should be compared with the entire fire site to determine whether it is the part of the fire that burns the most and causes the most damage. The initial fire site can be determined based on the collapse form of the building in this area, the shape and location of the smoke traces, the degree of burning, the door and window frames, beams and columns, etc., the direction of the interior furniture dumping and the level of accumulation.

2. The fire site can be compared with the internal side of the object in the center position of the fire point, and the burn damage on the side facing away from the object in the same direction, so as to determine the fire location.

3. The objects connected to each other in the fire field can be compared, and the direction of the burning and burning degree of the objects from heavy to light can be found and analyzed, and whether the fire part is consistent with the spread direction to determine the fire site.

4. If there is a corpse at the scene, it is necessary to deviate from the direction of the fire to escape according to the law that in the event of a fire, the person will deviate from the direction of the fire when it cannot be extinguished, and the direction of the foot of the corpse falling to the ground is generally the direction of the fire part.

When determining the location of the fire, it is also necessary to pay attention to some fine rules and unconventional special surnames:

1. When conducting on-site observation, the state of the burned object in the scene should be observed from multiple directions and angles;

2. Surveyors should first figure out the location and direction of their own observation point when observing at each observation point;

3. Don't miss any residual objects in the fire site at the scene, treat the residues carefully, study and analyze them carefully, and don't throw them away easily;

4. For the burned building, the floor plan of the indoor objects or equipment installation of the building before the fire should be obtained as much as possible, so as to facilitate comparative analysis;

……”

Xiao Ke and Xiao Cao listened carefully, and then took out their notebooks and began to record.

"Don't remember, the car is bumpy, don't hurt your eyes, when you go back to the office, take a good look at the book, the book I said is all there." I said with a smile.

"Captain Li, you know so much, how many books should you read?" Xiao Ke admired.

"Didn't you see Captain Li coming from the Jiangnan Police Station, all with books?!" Xiao Cao said.

"When the book is used, there is less hatred, and you should read more books when you have time." I reminded.

The two nodded earnestly again.

The driver drove the car directly to the Fenggang Town Family Planning Office, and we sat in the office on the first floor.

Staff officers of the fire squadron and others also came.

"Captain Li, Staff Officer Wu, this year is not completely over, so I invited you here, I'm really sorry." Team Leader A'an said politely.

"Case first, case first. You're welcome, you tell me about the situation first. "I got straight to the point.

"Director Zhang, you will find out about the situation." Team leader A'an arranged.

Director Zhang nodded and said:

"Because it is during the Chinese New Year, everyone is more sloppy at work, even if they come, most of them are not in the office, at most they sit in the office and leave. I left at three o'clock yesterday afternoon.

At about five o'clock this morning, Lao Liu, who was on duty at the unit, called my home and told me that there was a fire on the second floor of the family planning office. It's okay to say that there are no valuable, important items in my office; There are a lot of bills in this financial room, and in addition, the archives are stacked with files from the past years, what should I do?! ”

"Call Lao Liu on duty." I said.

Lao Liu came over soon, in his sixties, his face was full of soot, and his clothes were also full of smoke and dust, standing there, his hands drooping, on his sides, his eyes looked at Director Zhang from time to time, his face was very uneasy.

"Lao Liu, tell you to watch the door, why can't you see it well?! So many files and bills have been burned, what do you say to do?! What do you think you should do?! Director Zhang stared at Lao Liu, his eyes were about to catch fire.

"Director Zhang, Director Zhang, I got up at half past two in the middle of the night last night, and I turned around in the front and back yards, and I didn't find anything, who knew that I got angry soon after lying down. It's all my fault, it's all my fault, I didn't do my job. I'm sorry, I'm sorry. Lao Liu shook his head and said.

"Sorry, did it work?! Is it useful to know that it is wrong?! Director Zhang continued to be unhappy, raised his voice, and said.

Lao Liu didn't dare to speak anymore.

"Director Zhang, can we ask about the situation?" I was a little annoyed. When such a big thing happens, how can you, the leader, completely put the responsibility on an old man who cares for it!

"Captain Li, you ask, you ask." Director Zhang hurriedly said.

I pulled up a chair and said to Lao Liu:

"Master Liu, sit down, I have something to ask you. It's already happened, don't worry about it, cooperate with us and figure out the situation, which is more conducive to solving the case, you see, okay? ”

Lao Liu nodded, looked at Director Zhang, and still didn't dare to sit down.

"Sit down, sit down, sit down and answer Captain Li's question." Director Zhang's voice.

Lao Liu sat down in the corner of the chair, I took out my notebook, and asked:

"Master Liu, I'm from the Criminal Investigation Brigade, don't be afraid, let me ask you a few things, okay?

Lao Liu nodded.

"You will tell me about the fire from last night to the discovery of the fire, the more detailed the better." My voice.

Lao Liu opened his mouth and said:

"Last night it was eight o'clock, I walked through the front and back yards, and after making sure there was nothing out of the ordinary, I locked the front yard door and went to bed to watch TV. I watched and fell asleep in bed. When I woke up, it was two o'clock in the morning, and there was not a single TV station.

I got up, went to the toilet by the way, and then looked again in the front and back yards to make sure there was nothing abnormal, and then went back to sleep.

Who knew that at half past four, I smelled a puff of smoke, and when I got up and looked, I was startled, the second floor was on fire! I hurriedly called for people, called the people next door or so, and the people who lived next to the family planning office heard my shout, so they ran over, and many people came, and everyone helped me put out the fire. With everyone's help, the fire was finally extinguished. I hurriedly called Director Zhang again, and soon, Director Zhang came over.

That's how it is. ”

"Master Liu, I see that you remember the time very accurately, what's going on?" I continued.

"I've looked at my watch. I woke up at half past two in the middle of the night and found that the fire was half past four. Lao Liu slowly relieved himself.

"I'll look at your watch." I said again.

After taking Lao Liu's watch, I compared it with the BP machine, and the time was basically the same, so to speak, the time of the case was half past two to half past four.

After returning the watch to Lao Liu, I then asked:

"Master Liu, in the past few days, have you found any suspicious people or suspicious situations?"

"No, there have been fewer people in recent days, and people in and out are basically people from our unit, and there are no suspicious people." Lao Liu replied.

"Who took part in the firefighting?" I asked.

Lao Liu dug into the pocket of his jacket, took out a piece of paper, and said:

"These are all people who came to help put out the fire, and their names are all on it."

I took it and looked at it, the handwriting was not bad, it was more neat, there were not only people's names on it, but also what each person did, and in which store to do things, very detailed and specific, I counted, a total of 12 people.

"Master Liu, you have done a very good job in this." I'm sure in time.

"It's all my fault, I didn't keep an eye on the door and let the unit burn down." Lao Liu continued to blame himself.

"It's happened, don't blame yourself anymore, we'll find a way to solve the case." I was relieved.

Lao Liu nodded and did not speak.

I opened my mouth and said:

"Staff Officer Wu, Team Leader A'an, do you have anything else to ask Lao Liu?"

The two shook their heads.

"Okay, Master Liu, you go and rest first, and we'll call you if there's something." My voice.

After Lao Liu left, we went up to the second floor together.

In the middle of the second floor is an east-west corridor, with offices on the north and south sides of the corridor. At the east end of the corridor, the ground was covered with stagnant water, and after wading through the stagnant water, I scanned my eyes and found that three offices had been burned, and the edge of the door frame of the office was marked with small wooden signs that read "Director's Office", "Finance Office", and "Archives Room", and there was a lot of dust attached to the small wooden signs.

The director's room and the financial room are located on the south side of the corridor, and there is a wooden door at the west end of the south wall of the director's room, the wooden door is open, and a little smoke and dust can be seen on the outer door panel, and there is more smoke and dust on the inner door panel, and there are traces of burning, which indicates that the fire started to burn from the room; The door lock has obvious traces of prying, and upon closer inspection, it is found that there is a 7cm wide mark on the edge of the wooden door frame, so the door frame should be the entrance and exit of the perpetrator's house, that is, the door is prying. The entire interior wall is blackened with smoke, in different shades, white in some places, black in others, and the closer you get to the ceiling, the darker the black; There is a window in the south wall, the glass is broken, and the inner window frame is gradually reduced from the bottom up; There is also a lot of stagnant water on the floor indoors, and there are traces of paper left after burning in the middle position, which must be artificial, and the surname of the case can be determined by this, which is arson! There is a wooden cabinet in the southeast corner of the room, the door of the cabinet is open, and the documents, papers and other items in the cabinet are messy. There is a desk in the northeast corner, and the table top also has burn marks, to a lesser extent.

The situation in the Finance Office is similar to that of the Director's Office.

The archives are located on the north side of the corridor, and the situation is much more serious. Most of the contents of the filing cabinet were taken out and placed on the ground in the middle of the room and burned, and the floor was covered with burning soot, which further determined that the case was arson.

Xiao Ke and Xiao Cao quickly took pictures of the scene and related traces and physical evidence.

Staff Officer Wu also led people to investigate.

I gently pushed the window on the east side of the hallway, and the window opened in response, and the sunlight after the rain shone in directly, and a few mud marks were clearly visible on the windowsill.

I poked my head out to see a cast iron sewer pipe running from the first floor through the second floor to the third floor, and on the second floor, there were also a few traces of mud rubbing, the mud was black with a light red color.

"That's import and export." I said.

Everyone nodded, and as I went down to the sewer pipe on the first floor, there were more messy mud marks on the ground, and we followed the mud trails to the backyard.
