Suddenly, I felt that the clothes of the deceased were a little familiar, so I walked two steps to the front of the deceased to see his appearance, but was surprised to find that the deceased was actually Lao Guo.

Didn't Lao Guo live on the second floor? How can you fall from the third floor or above? Could it be that he killed? That's not right, all the windows in the tube building are blocked by anti-theft nets, and there is no way to chase down from the windows, how did he fall from the building?

I subconsciously looked upstairs, and suddenly found that there seemed to be a figure watching the movement below at a corner at the top of the building. There are people on the roof, and the murderer is on the roof! ”

There were six floors in the building, and by the time I got to the top floor, I was out of breath, and when I saw the open door on the rooftop, I ran over with all my strength.

But when I saw the person lying on the guardrail looking down, I was even more dumbfounded, that person was actually Lao Zhang, the manager of the dormitory!

"Uncle Zhang? How did you end up here? ”

Lao Zhang hurriedly waved his hand and looked at us excitedly and said incoherently: "Comrade policeman, I didn't kill anyone, I really didn't kill anyone." I really didn't kill the person, I just came up and there was no one on it, so I looked down, but I didn't expect someone to jump off the building. ”

I swept around the rooftop, and there was nothing around it, only a large pond for storing water, and no hangers for drying clothes. And how could it be so coincidental? Someone dies and he happens to be on it?

No, when I swept to a railing out of the corner of my eye, I suddenly noticed that there was smoke in a place, how could there be something smoking here? Something is on fire?

I hurriedly ran to the railing, peeked in, and found an incense burner on the edge, the style of the incense burner was exactly the same as the one I saw at the scene of Du Xianchao's death, at this time the incense burner was burning three incense sticks, the incense had just burned a top, and it seemed that it had just been lit.

Lao Guo jumping off the building is not a suicide case? Is it a homicide case? And the murderer in both cases is the same person. And Lao Guo and Du Xianchao had a good relationship before, and after thinking about it, I was very afraid, is there any clue in this? At this time, only Lao Zhang is on the rooftop, is he the murderer?

"Wait, tell me what happened, why are you here? How could Lao Guo jump from here. ”

Lao Zhang's emotions became even more excited, and he hurriedly said: "Lao Guo is dead? Comrade policeman, I really didn't kill people, I really don't know anything, when I was cooking below, Lao Guo ran over and said that I wanted to go to the rooftop, saying that I had something to say to me, I thought he couldn't think about it, and wanted to jump off the building to find his wife, so I ran up in a panic, how did I know that I didn't see anyone after coming up, I just stretched out my head and looked down, and found that there was a person lying on the ground, so I knew something bad, but I really didn't kill anyone. ”

I put on two breaths and asked, "You said that Lao Guo called you up?" Did he call you up? Or is it someone else's talk? Did anyone else see it at the time? ”

Seeing Lao Zhang's red face and red ears with an excited expression, and he couldn't stammer, I had to comfort him: "Don't worry, speak slowly, if you are really not a murderer, the police will not frame a good person." ”

As I spoke, I turned around and pointed to a new comrade behind me and said, "You go and call the city bureau and ask them to send someone, it's best to let Brother Bin come over to investigate the scene, he is an expert in this area." ”

Considering that the scene of the fall below was unattended, I asked another person to go downstairs to guard the scene and wait for the arrival of people from the city bureau.

"Uncle Zhang, let's go downstairs and talk slowly, don't worry, if you are not a murderer, we will never frame you."

"Okay, I'll tell you."

I pulled Lao Zhang down the stairs step by step, Lao Zhang's emotions on the way were very excited, and his mouth trembled non-stop, until he calmed down a little when he was in the duty room.

"Comrade policeman, let me tell you, I was stir-frying here at the time, and then Lao Guo stood at the entrance of the building and shouted, I immediately turned off the fire and went upstairs after hearing it, and then ran upstairs, when I got upstairs, the rooftop door was still closed, I pushed open the door and didn't see anyone, you know the things behind the police comrade."

Lao Zhang gestured while talking, and I saw that his movements and expressions did not look like fakes, so I pondered the authenticity of what he said. Although Lao Zhang's body is also old, it must be better than Lao Guo's, Lao Guo struggles to move his steps like that, but Lao Zhang said that he immediately went to the rooftop after hearing Lao Guo's voice, and still ran up, and when he went up, the person was gone, and it didn't make sense here.

Thinking of this, I couldn't help but wonder: "Are you really seeing what he said?" ”

Lao Zhang shook his head: "That's not true, I heard his voice, but I didn't see his people, he was standing here at the top of the stairs, and I couldn't see the situation here in the duty room." ”

I immediately asked again, "When you went up, the rooftop door was closed?" Is the rooftop door usually open or closed? Where is the key? ”

"When I went up, the rooftop door was closed, not locked, and the rooftop was usually open, because residents sometimes had to go up to the rooftop to dry pickles, so the door was never locked and there was no key."

When I heard him say that, my first reaction was that this is impossible! Lao Guo's body can't run past him, if it runs up for the first time, it will definitely bump into Lao Guo before going to the rooftop, but according to what he said, he ran up after hearing the sound, but it was still a step too late, Lao Guo couldn't go up by elevator, right? I saw him fall from the upper floors with my own eyes, this can't be faked, but according to what Lao Zhang said, it can't be explained anyway. And the most important thing is that there is an incense burner on the rooftop, and the incense on the incense burner has just been lit not long ago.

Thinking of this, I had to say in embarrassment: "Wait for someone to come, I haven't done a scene investigation now, and I can't tell if what you said is the truth." ”

"Comrade policeman, I really didn't kill anyone, you have to believe me, how can I have the courage to kill someone, I have always been an honest person, and I have never done anything wrong......"

Seeing his excited face, I had no choice but to comfort: "Uncle, don't worry, if you don't kill anyone, we will return your innocence." We will never frame a good person, but now there are a lot of doubts in the case that have not been resolved, so I don't know whether you are the murderer or not, even if I say no, the police station is not the only one who speaks, they all speak according to the evidence, and when someone comes to investigate, you will tell them everything completely, from how you cook the food to what happened on the rooftop. ”

"Okay, okay, I must be sure, I will cooperate with your work, and you will return my innocence."

After a while, Zhang Bin arrived at the scene with four people, and I walked out to greet him: "Brother Bin, this case is very strange. ”

Zhang Bin walked to the place where Lao Guo fell from the building and looked at it, and said to me: "Tell me about the situation, you have also seen strong winds and waves this year, what are you worried about?" ”

I smiled bitterly and said, "It's not a panic, it's that this case is really strange, you let other people watch below, and I'll take you to the rooftop to see you." ”

When I went upstairs, I told him about Lao Zhang's situation, Zhang Bin also tightened his brows, I took him to the fence, when he saw the incense burner, he couldn't help but lose his voice: "The same incense burner?" Is he the murderer? ”

"It's hard to say, but it's really very likely, if he can't outrun Lao Guo, I don't believe what Lao Guo says, but that's what he said, and I'm a little confused."

Zhang Bin stared at the incense burner for a while, and said thoughtfully: "Wait, he's the dormitory administrator, right?" He stays in the tube building every day, and the one who has the most chance to commit a crime is probably him, and this person seems to have all the conditions to commit a crime, but I don't understand it a little, if he killed him, he pushed the deceased downstairs and ran away immediately, staying at the scene and waiting to be arrested? If he didn't kill him, someone else planted it, and the clues forged were not enough to convict him, it's really a bit strange. ”

I looked at him helplessly: "Now you know my suffering, no matter what, both of them seem to lack some crucial evidence, no matter which way you lean." ”

"It's okay, it's not a big problem, you bring a flashlight, I'll survey the traces of the scene, if the old man kills, he will definitely leave some evidence." When the time comes, he will be at a loss. ”

Zhang Bin put on gloves and began to inspect from the entrance of the rooftop, and soon extracted a few footprints, as well as a few palm prints on the dusty railing. Leaning over and gently picking up the incense burner, Zhang Bin took a closer look at it and handed it to me: "Look at the style of this incense burner, is it exactly the same as the one found on the bed in Du Xianchao's house in the morning." ”

I put on my gloves and took them to look at them carefully, and said with certainty: "It is indeed the same, if the fingerprints extracted from the two incense burners are the same, it is even more certain that the murderer belongs to one person." ”

Zhang Bin suddenly said: "I just thought of a possibility, could this be imitation killing?" ”

I hesitated for a moment and asked uncertainly, "Are you saying that someone saw the scene of the crime in the morning, and then imitated killing Lao Guo?" It's the dead. ”

"Yes, did you say there was such a situation?"

I pondered for a while, combined with today's investigation, and finally shook my head: "This is unlikely, because I investigated a clue today, more than ten years ago, Du Xianchao had a good relationship with the deceased, and then slowly lost contact, I think the two of them must have some inevitable connection with the deceased, or a common hatred, so the murderer killed both of them." ”

"Perhaps, let's go down and take a look first, there is no hard evidence now, it's too early to say anything."

"Yes, I'll wait for the test results to come out."

Zhang Bin and I went downstairs, took pictures of the corpse for evidence, and asked people to carry the corpse into the police car and transport it back for Ma Zhiyuan to do an autopsy to see if he died from a fall or other reasons.

As for Lao Zhang, we didn't bring the person back to the police station, and now the test results have not come out, and bringing them back to the police station is not of much use, so I made a record of him and asked him to go back and wait for the results.

Before leaving, Lao Zhang also said with a handful of snot and tears that he didn't kill anyone, let us return him to a clean house, and finally I calmed people down, thinking that Sun Jianguo said that there was a meeting at seven o'clock, and it would be more than six o'clock, so I left Dafeng Factory and got in the car to go back to the city bureau.

On the way, I asked Zhang Bin how the autopsy was today, and Zhang Bin shook his head: "It's a little troublesome, don't you see that I and the deputy captain have gone to be staff officers, and the previous autopsy work can be done by Ma Zhiyuan alone." ”

"What's the trouble? Is it still troublesome to have last year's 7.14 corpse case? ”

"You don't understand, these two can't be compared at all, when we restore the time of death, we were surprised to find that according to the detection of the death time of the corpse, we found that the detected death time is not the same, and the gap can be one day!"

I remember that the corpse was divided into seventy-nine parts, and when the forensic doctor encountered this situation, he would definitely take multiple samples and tests, and then calculate the test results, under normal circumstances, if there is a gap of one day, it will not be too big, but it is difficult to understand the gap of one day like this, so he repeated the sentence in disbelief: "The time of death is not the same?" Can the gap one day? How is this possible? Could it be that they died piece by piece? ”

"Definitely not, but there must be a reason in it, Ma Zhiyuan seems to have called his mentor, I don't know what the situation is now."
