Chapter 49 There is a surprise on the roof! (Seek the first order to ask for a monthly pass)

When Xia Yan and Zhou Zheng returned to the scene, the cordon had already been pulled up, and the onlookers at the scene had been dispersed, and some of the criminal police were taking notes on the witnesses at the scene.

After experiencing such an incident in the Blue Rain Community, more lights were turned on obviously, and too many families discussed after going back, chatting about what they saw and heard just now.

Zhou Zheng kept memorizing the route along the way, thinking about it in his head, and his stomach grunted.

"Master, Bureau Qin is here."

After Zhao Lei saw Xia Yan came back, he took the lead and ran over to meet him. He kept blinking and said in a low voice, "Ju Qin is very angry."

"Can you not be angry when this kind of thing happens!" Xia Yan nodded helplessly. Regardless of what happened during the day, two fires broke out just at night, and corpses were found in the fire scene. The nature was extremely bad, and he said: " I'm going to see the scene."

"Master, I think you should go to Bureau Qin first." Zhao Lei pursed his lips and said.

"All right." Xia Yan glanced at Zhou Zheng next to him, and said, "Go and see Bureau Qin first..."

Zhou Zheng didn't say anything, his brain was still thinking quickly, what happened now, one after another, was laid out in front of him, there was almost no room for breathing, no time to calm down and think at all.

However, this is not a reason or an excuse. As a forensic medical staff, no matter how difficult the conditions are, they must be overcome.

Zhou Zheng followed Xia Yan to Qin Wangde, and he could tell from his body language that Qin Wangde was in a bad mood from a distance.

"Qin Bureau." Xia Yan and Zhou Zheng went over to say hello together, but Qin Wangde's expression was obviously stern, and his eyes were full of majesty.

"Xia Yan, what's the matter with you, as the captain of the criminal police team, why are you still pretending to be missing!" Qin Wangde's tone was quite serious, and he said coldly: "When we arrived, only Zhao Lei was guarding At the scene, if the fire brigade hadn't helped protect the scene and appease the masses, the consequences would have been disastrous!"

"This is indeed what I did wrong!" Xia Yan didn't argue, and actively admitted his mistake with a very correct attitude.

"Tell me, why did you go!" After Qin Wangde said a word, his anger subsided a lot, and he also understood that Xia Yan was not a person who acted without authorization, so he said: "You obviously arrived before us, but He disappeared again, you have to give me a reasonable explanation!"

"Qin Bureau, it's like this. We should have seen the suspect just now. We immediately chased after him, but it was too dark and let him run away." After Xia Yan got the opportunity to explain, he immediately explained the reason and said: "At that time, the matter was urgent and the suspect was running, so I had to catch up."

"Suspect?" Qin Wangde's eyes widened suddenly. He didn't expect that he would get such an answer. The dissatisfaction on his face suddenly dropped, and he asked, "What's going on?"

"Let me say it..." Zhou Zheng repeated what he had just explained to Xia Yan, adding some details, and correcting the work in the murderer's eyes from the scene of the fire to their expressions after seeing the scene of the fire.

"You mean to say that the suspect at the scene of the arson is most likely the suspect in the puppet case, and this person has a mentality of wanting to provoke the police." Qin Wangde concluded.

"That's it." Zhou Zheng nodded.

"I understand the situation, you handled it correctly in an emergency, and you did a great job!" Qin Wangde nodded seriously, and explained: "You haven't been to the scene yet, the trace inspectors have arrived, you go and have a look If there are any clues, as long as you find enough evidence to support the merger, write a report to me immediately."

The two cases and one serial case are of completely different nature.

From a bad point of view, it must be the serial case that has the greater impact.

but……

Under the premise that the serial case has already appeared, if other bad cases occur, the impact will be greater than the serial case continuing to commit crimes!

Based on this mentality, Qin Wangde would rather be the murderer of the serial case and continue to commit crimes, and he does not like to have more cases on the basis of the serial case.

Zhou Zheng first followed Xia Yan to the trunk of the car and took back the exploration box, then the two of them walked towards the fire scene together, and when they stepped into the corridor, they had already forgotten all the guesses in their hearts.

What we need to do now is not to guess, but to investigate. There must be no preconceived notions, and everything is based on factual evidence.

"The scene of the crime is on the sixth floor. The Blue Rain Community is an old community, and there is no elevator, which means that the only entrance and exit to the fire site is this staircase." Xia Yan said in a deep voice, "I don't know how the people's records are done. There are no witnesses, the murderer should have ran out of the stairs as soon as the fire broke out."

"The stairs here are not too narrow. The place where the fire broke out was on the sixth floor. After the residents in the building learned the news, even if they rushed downstairs to escape, they could avoid congestion and stampede incidents. This is unfortunate. Fortunately." Zhou Zheng analyzed.

"Indeed, if any other accident happens, it will be even more troublesome." Xia Yan breathed a sigh of relief.

The stairs are extremely dark, and they are all illuminated by the lights of the two people's mobile phones. The voice-activated lights in the corridor will no longer light up because of the timely power outage, and there are messy black footprints on the stairs in the flow of light and shadow.

These footprints should have been left by firefighters.

Zhou Zheng judged silently in his heart, as they got closer to the fire scene, they could already smell the burning smell.

"arrive."

After Xia Yan took the lead to step up the stairs on the sixth floor, his eyes fell on a house with an opened door in front of him.

There are also several trace inspection staff at the scene who are extracting some traces in the fire scene.

When Zhou Zheng followed up, he looked into the house. Inside the open door, the light of the flashlight was turning back and forth. There was water everywhere on the ground, and the pungent smell continuously drilled out along the door, which instantly made his nose feel very uncomfortable. uncomfortable.

This is the smell brought by the burning of the fire. It is not clear what the smell is. It is very complicated. Generally speaking, it only appears at the fire scene, and different fire places have different tastes.

For example, in a fire scene in a library, most of the burning materials are paper, and the main gases in the fire scene are carbon monoxide and sulfur dioxide produced by incomplete combustion of plant fibers, and the smell will be very pungent and pungent.

Now the smell here has a stink of burning plastics, burnt smell of burning protein, and pungent smell of burning wood.

In short, the smell in the corridor is complex and lingers for a long time.

As the two of them went upstairs, the higher they went, the stronger the smell became. Now that they were at the door, before entering, they felt that the inside was filled with poisonous gas.

Zhou Zheng and Xia Yan looked at each other, and they could see the determination in each other's eyes. Neither of them flinched because of the smell of the fire.

"Captain Xia, I have disposable masks and shoe covers here. Let's put them on before going in. After a brief inspection, we leave with the corpse. The scene of the fire is not suitable for the first inspection, but more suitable for searching for clues later. It's time to re-investigate." Zhou Zheng said in a deep voice.

"Yeah." Xia Yan's face was gloomy, the smell here made him feel as if he was suffocating.

Zhou Zheng squatted down to put down the exploration box, opened the box skillfully, and took out disposable shoe covers, gloves, masks, etc. from inside.

These items are very easy to find, and they are located in the most eye-catching place of the exploration box. After all, these items are the first thing to get every time you go to the scene.

Zhou Zheng handed these disposable items to Xia Yan, and the two wore them together.

After wearing it, Zhou Zheng took out the camera in the exploration box and found that there was still a flashlight inside.

It has to be said that after wearing the masks, their nostrils are much better, and many invisible particles in the air are blocked by the filters of the masks.

"Let's go in and see."

Zhou Zheng holds the camera in his left hand, turns on the video recording mode, and holds a flashlight in his right hand for lighting, which is very reasonable to match together.

After entering the scene, I realized more deeply what it means to be beyond recognition. I can still smell the strong burnt smell through the mask. I can’t tell whether it’s the smell of human flesh, wood or plastic. The smell here is completely gone. Messed up.

On the floor of the living room, there is a circle of strange special wreckage, which is clustered and moves towards the middle. These wreckages melted on the ground, and some filaments can be seen, covered with charred black paste.

There are fragments of light bulbs in the wreckage, and the tiles on the ground have broken into many pieces, giving people a feeling of nowhere to stay.

In the living room, two trace inspectors were squatting on the ground with spoon-like tools in their hands, scraping the scorched material on the ground, and then putting it into the evidence bag for inspection.

"Has the gas at the scene been collected?" Zhou Zheng asked the trace inspectors at the scene.

"Samples have been taken." The trace inspector replied.

"I've taken it here too." Zhou Zheng looked at the wreckage in the ground.

"Well, I've taken it, and I'll test it tomorrow." The trace inspector replied again.

"Ah."

Zhou Zheng nodded. He squatted down slowly, holding a flashlight to shine on the traces on the ground, his eyes full of thought.

From time to time, he changed the angle of the light in the flashlight. Through different positions, he could refract the traces on the ground from multiple angles.

Looking at it this way, it took more than three minutes.

Zhou Zheng's solemn eyes focused on the traces on the ground through the glasses, thinking while watching, finally nodded silently, and slowly got up.

"Zhou Zheng, did you find anything?" Xia Yan asked urgently. He had been holding back for a long time. He watched Zhou Zheng's movements and didn't dare to disturb him at all. Now that Zhou Zheng was getting up, he couldn't hold back the feeling in his heart. doubts.

"One thing, let me think about it, and I'll confirm it again."

Zhou Zheng changed the angle on the basis of not destroying the scene as much as possible.

In fact, after the fire scene has gone through the process of fighting the fire, the scene has changed beyond recognition.

Zhou Zheng looked up at the ceiling, picked up the flashlight, and found that all the light bulbs on the ceiling of the living room had been shattered, leaving only the dark golden metal frame in a state of fusing, with flowing smoke traces on the top.

"Zhou Zheng, what did you find out?" Xia Yan couldn't help asking again, this kind of silence made him very depressed.

"The wreckage on the ground should be mannequins!" Zhou Zheng immediately said something that shocked Xia Yan.

"So it's related to the puppet case?!" Xia Yan's breathing became rapid.

"Judging from the traces on the ground, this is a central fire point." Zhou Zheng said in a deep voice.

"You still understand this?" Xia Yan frowned fiercely.

"The biggest feature of the central fire point is that the charcoal ash layer is between the ground layer and the rubble layer." Zhou Zheng squatted on the ground, touched the burnt surface of the ground with his fingers wearing disposable gloves, and said: " right here!"

After finishing speaking, Zhou Zheng raised his head to look at Xia Yan, and nodded to Xia Yan.

"The fire started on the ground, and it can be determined from the burst marks of the floor tiles and the exposed concrete flakes under the floor tiles. If the fire broke out at the top, the ground layer would not be destroyed like this."

"Only the floor tiles at this location in the living room were burnt, and the traces of the explosion radiated outwards in the shape of a spider web, which also proved that the temperature at this location was the highest."

"The combustion of combustibles at the fire point can cause the produced charcoal ash to fall on the ground and form a charcoal ash layer. As the fire continues to develop, the temperature rises, causing the hot air to spread upwards, thereby burning the upper furnishings or structures, making Debris fell onto the charcoal layer at the lower fire site, forming a rubble layer."

"The remains of the suspended ceiling and the fragments of light bulbs on the ground form the unique rubble layer here, and the dark residue below is the charcoal layer here."

"These residues of the charcoal ash layer should be fiberglass fibers, and the black substance covered on them should be the product of incomplete combustion of epoxy resin, and fiberglass and epoxy resin are the main materials of mannequins."

"In the rest of the places, the charcoal ash layer covered the rubble layer, forming a layer of burnt special charcoal ash layer boundary."

"So I conclude that this is where the fire started!"

Zhou Zheng analyzed one sentence after another. Just now he carefully observed the details of the scene here with a flashlight, and then made a judgment based on the knowledge he had learned.

Even though this was his first on-site inspection of a fire scene, he still did not rush around, but patiently searched for details.

"I can't see that you know a lot about the fire scene!" One of the trace inspectors looked at Zhou Zheng in surprise. He couldn't make such a clear guess here. Most of the fire scene accidents are handed over to the fire department for identification. of.

"I read some books when I was in school." Zhou Zheng said modestly.

"I have a question. How did you determine that it was a puppet? You can't burn enough materials?" Xia Yan looked at the scene repeatedly with the light of his mobile phone. He was sure that something was burned here. But under the complete transformation, there is only a dark patch on the ground, and the judgment of the puppet is of great significance to him.

"Captain Xia, look for yourself. Dividing this place, does it look like there are a pair of feet on each floor, but there are strange things covering the feet? Judging from the remnants, it should be standing here. There are a lot of model dolls." Zhou Zheng squatted on the ground carefully looking at the charred paste, and took a camera to record the images.

"It's kind of like..."

Xia Yan blinked his eyes hard and looked towards the ground, the scorched black paste was still emitting a pungent smell, and the residual temperature made his eyes not particularly comfortable, but after Zhou Zheng's words, he could Going to see it, I think this is the case.

Immediately afterwards, Xia Yan looked around this place again, and nodded silently.

"The footprints here are all facing the direction of the balcony, indicating that these doll models are neatly placed here. Judging from the traces left on the ground, they collapsed towards the central store, which is the classic direction of the fire scene. From this, it can be deduced that this is where the fire started!" Xia Yan said with bright eyes.

"As expected of Team Xia!" Zhou Zheng praised.

"Put it down quickly, don't flatter me, you discovered this, but it just came out of my mouth." Xia Yan waved his hand.

"The light at the scene was too dark, and the material on the ground was black. If it weren't for the fiberglass fibers pointing out the direction of the collapse, it would be very difficult to tell. But after tomorrow dawn, you can tell at any time, Team Xia," Zhou Zheng added. Here comes a rainbow fart.

"Who did you learn from, kid?" Xia Yan said with a slight twitch at the corner of his mouth.

"The teacher of the school." Zhou Zheng was stunned for a moment, he didn't expect Xia Yan to ask such a question.

"I'm talking about flattery, how could I remember that you didn't know this before!" Xia Yan complained.

"Captain Xia, it's not that I've been with you for a long time, and I've been gradually infected." While Zhou Zheng was speaking, he looked carefully at the location of the fire they had judged, and with a light hang of his hand, he said, "The glass fiber reinforced plastic here There are obvious traces of stacking of fibers, but the paste-like charred matter is the least, and there is a viscous liquid under the paste, which is the most violent place in this area, and there are combustion-supporting materials!"

"The carbonization of the ground here is also the most serious. Extract the substances here and go back for physical and chemical tests to see what kind of combustion aid it is!" Xia Yan immediately said to the trace inspector next to him.

"It's already been extracted." Hen Jian couldn't complain. The two of them analyzed on the spot for a long time. Although what they said made sense, they were not vegetarians, and everything that should be extracted had already been extracted.

"Where are the corpses?" Zhou Zheng asked suddenly, as if they didn't care about the corpses at all before, as if the firefighters came to review the scene, but only he knew in his heart that the wreckage in the living room was most likely the For puppet models, as long as the identification results confirm this point, it is providing a basis for the merger.

"It's really time to look at the corpse." Xia Yan's expression became serious. The doll model can only be the basis for joining the case, but it is not conclusive evidence. The DNA of the corpse and the head must be compared and identical, so the firefighters The three headless corpses in the mouth are crucial.

"The corpse is in the bedroom. It's very miserable. You should be mentally prepared before going in." The trace inspector kindly reminded.

Zhou Zheng walked towards the bedroom, which was in a mess. There was a big bed in the most conspicuous position. Except for the steel ring around it, almost everything was burned and completely collapsed.

The ceiling of the bedroom had collapsed under the burning of the flames, and it was broken on the bed together with the lamp group. There were all kinds of broken bricks on the floor, and the surrounding walls were sooted into blackness, and all were covered with water. The stains were soaked, and there was still stagnant water mixed with stains on the ground.

Zhou Zheng stood at the door and looked inside. The accumulated water on the ground continued to reflect the light of the flashlight. At a glance, apart from the wreckage, there was no corpse.

"Zhou Zheng, did you see it?" Xia Yan asked in a low voice.

"No, what about you?" Zhou Zheng kept searching with a flashlight.

"Nonsense, if I saw it, would I still ask you?" Xia Yan shook his head.

"It can be determined that the bedroom is the second fire point of the fire. The fire point in the living room is far away from the bedroom, and there is no trace of fire spreading. The burning degree in the bedroom is obviously heavier, even heavier than the living room. The damage In this state, the fire should have started here first." Zhou Zheng stood at the door of the bedroom and analyzed.

"This bedroom is on the shady side of the Blue Rain Community. When the fire truck arrives, the open fire in the living room will be extinguished first. The bedroom needs fire fighters to enter the room, so even if it is the last fire here, it will still burn. Longer." Xia Yan then analyzed: "However, I agree with you, this should be the first place to burn, if the perpetrator first sets fire to the living room and then to the bedroom, it is easy to trap himself in the fire. "

"Then...that is to say...the firefighters found the body after putting out the fire."

Zhou Zheng stepped into the bedroom. The light of the flashlight in his hand kept moving. The clear beam was looking for the corpse, but it still couldn't be seen from the bright side.

"I probably know where the body is."

Zhou was walking towards the bed, his brain was thinking quickly, the bedroom was burnt to such a state, if you don't look carefully, you can't see the corpse at all, so it won't frighten the firefighters to that extent.

"The firefighter should have discovered the corpse by accident, that is to say, he should extract the traces at the location of the fire. The burn marks on the bed are the strongest, and this is the most likely fire point. Then the firefighters should investigate the location... ..."

Zhou Zheng stepped on the stagnant water, came to the side of the bedstead that was pressed by the ceiling, and looked directly into the bed from a top-to-bottom angle. When the light of the flashlight shone there, the charred and charred corpse was already appear in sight.

Three charred corpses were pressed under the bed frame, and the heavily carbonized skin showed cracks in the form of smooth skin. The overall visual effect looked terrible, and the three corpses were all headless.

Zhou Zheng couldn't help wrinkling his nose because of the strong smell of burnt barbecue.

Just imagine, if the firefighters were extracting traces here, the scene would have been dark, and the corpse was also pitch black. When the light shone on it, it would indeed easily cause that feeling of fright.

"There are three corpses here, and they are all headless corpses. If it is really related to the puppet case, then we still have a head that has not been found!" Xia Yan said in a deep voice.

"The murderer should have planned to burn the body here a long time ago, but there was a problem with the timing. If I guessed correctly, his original plan was to arrange the scene of the third head, but where is it?" How about asking him to burn the scene ahead of time?" Zhou Zheng didn't examine the corpse, and in this case, the corpse is not so easy to move, instead, it's better to keep the scene as it is and feel the murderer's feelings firsthand.

"Until now, we haven't made any breakthroughs. It stands to reason that we won't pose a threat to the murderer at all. Could it be..." Xia Yan suddenly realized something, and said, "Could the murderer know that we are going to attack the Blue Rain Community tomorrow?" Did you investigate?"

"Are you alarming the snake?" Zhou Zheng frowned slightly.

"I'm not sure about this either. People in the team did come here at night, but they didn't do anything obvious. Is the murderer's anti-reconnaissance awareness so strong?" Xia Yan suddenly felt incredulous.

"possible."

Zhou Zheng couldn't think of other possibilities for the time being. After looking around in the bedroom, he walked towards the window. Due to the high temperature of the fire, the glass at the window had already broken.

"Captain Xia, come and take a look. Can you see the teaching building of the art department of Jianghai Normal University and teaching building No. [-] from here?"

"The location seems to be about the same." Xia Yan couldn't be sure in his heart, as it was so dark outside that he couldn't see anything.

"I can only bring a telescope tomorrow to try it out. If it can be matched, and the DNA of the corpse is the same, this should be the place where the murderer of the puppet case dismembered and hid his body. It may also be the first scene of the murder case." After careful exploration, we may still be able to find some traces, but it is very difficult." Zhou Zheng's eyes were quite serious, and when he saw the puppet in front of the piano, he realized that this case was not simple, but he did not expect it to become so complicated .

"I'll do all of this tomorrow. I hope that nothing will happen during this difficult night." Xia Yan's body can be considered relatively good, but after going through the repeated tossing and tossing on the scene, he is also a little bit powerless.

"Captain Xia, let's transport the corpse out together."

After Zhou Zheng continuously took pictures of the location of the corpse, he looked towards Xia Yan, and the two went together to find the other two trace inspectors in the living room.

After the trace inspection personnel extracted as many traces as possible from the fire scene in the bedroom, they put the three headless corpses into body bags and carried them downstairs.

When the last corpse was carried out by Zhou Zheng and Xia Yan, Zhou Zheng suddenly stopped at the door and looked towards the opposite door.

The Blue Rain Community is an old-fashioned residence. There are two households on the first floor, and the other household is tightly closed.

"Captain Xia, do you know who lives opposite?" Zhou Zheng asked suddenly.

"It's not clear yet." Xia Yan shook his head.

"What about the upper floor?" Zhou Zheng looked up towards the top of the stairs. The sixth floor is not the end of the stairs, there is still half of the stairs going up, and there is a ladder beside it.

"It should be the roof up there!" Xia Yan stared at it.

"Captain Xia, wait for me."

Zhou Zheng gently placed the body bag containing the corpse on the ground, then quickly climbed half a floor to the side of the ladder, carefully looked up the ladder, and then looked at the ground where the ladder was located.

Suddenly, he had an indescribable feeling in his heart, as if the ladder had life, beckoning to him, telling him to go up and have a look.

The location of this ladder is really a bit abrupt, it doesn't look like it has been placed here for many years.

"Captain Xia, let's send the body down first, and then go to the roof to have a look. The ladder doesn't look like it's been there for a long time. There's no dust on the ladder. It doesn't look like it's been here for a long time."

"You mean..." Xia Yan frowned slightly, and said, "Is this ladder set by the murderer?"

"It's not impossible." Zhou Zheng nodded, got down again, lifted the body bag, no matter what, he had to transport the body back first.

"Wait, I just realized that you suspect that there is something on the roof, right?" Xia Yan's eyes suddenly widened, with inexplicable surprise flashing in his eyes.

"We'll find out when we look at it."

Zhou Zheng didn't say much, it's not that he didn't want to say it, but he couldn't figure it out, it's just that he had such a feeling in his heart.

There might be something on the roof!
that ladder...

Looks like it was put in there not long before the fire!
Zhou Zheng forcibly suppressed the urge to climb up immediately, took the body bag downstairs with Xia Yan, and after arranging his work, he looked up towards the roof.

Above the sky, the heroes are shining brightly.

The bright moonlight shone on the residential building that had just experienced a fire, adding a lot of mystery to the building.

What kind of scenery will it be on the roof?
The question mark in Zhou Zheng's heart was getting bigger and bigger. While he was waiting, Xia Yan had already reported to Qin Wangde and walked over with three criminal policemen.

"Zhou Zheng, it's getting late, and I'm not sure what's on the roof. Why don't we let the Criminal Police Team go, and you can just stay here and wait for the news." Xia Yan said sincerely.

"I'll go up with you." Zhou Zheng said firmly, "I found the ladder. I need to feel it myself, maybe I can find some clues."

"Okay, then you follow us and protect yourself." Xia Yan didn't insist anymore.

"Let's go." Zhou Zheng urged, he couldn't wait to see what was on the roof.

Climbing up to the residential building again, Zhou Zheng suddenly felt that his legs were filled with lead, extremely heavy and sore, he couldn't help pinching his thighs hard, but felt that the strength was not enough, so he clenched his fists and hammered heavily a few times.

"Your legs are sore!"

Xia Yan noticed Zhou Zheng's movements, smiled slightly, and said, "You usually do too little exercise."

"We went back and forth to this building three times, which is equivalent to climbing twelve floors and going down another twelve floors. It's normal for our legs to be sore." Zhou Zheng gritted his teeth and said.

"Are you sure you want to go?" Xia Yan asked again.

"superior."

Zhou Zheng endured the soreness in his legs and once again climbed to the second half of the stairs on the sixth floor. When he saw the ladder again, the feeling of being called was even stronger.

At this time, he re-examined the ladder, and realized that the feeling was not that the ladder had any life, but the abrupt placement, which was like the unique sense of ritual presented by the murderer of the puppet case, as if it was conveying the meaning of life through the ladder. discourse.

Come up quickly!

There are surprises upstairs!

Zhou Zheng didn't know whether his interpretation was correct, but in his heart, this feeling was extremely strong, and at the same time, his curiosity was completely mobilized.

"Captain Xia, let's go up, don't delay too long!"

Zhou Zheng's tone was quite low, and a strong sense of foreboding emerged in his heart.

Three headless corpses, two puppet heads, and one head...

where is it?
