This year, just after the National Day, the autumn wind began to blow slowly over the earth, and the autumn coolness gradually invaded people's bodies and minds.

But in this harvest season, a tragedy occurred on a construction site in Longsha Town, where an honest migrant worker brother died at the construction site.

When I received a call from Lao Lu and rushed to the scene, it was already 9:05 in the morning. The weather was gloomy and gloomy, as if the autumn rain could fall at any moment.

A police cordon has been set up on the construction site, and outside the cordon, many villagers and workers on the construction site can still be seen stopping and watching, and most of them are discussing.

I like to listen to the opinions of the people around me, of course, I will take these discussions as a reference or a direction for solving the case, but I will never use these remarks as the basis for judging the case.

Since I'm not a police officer, I'm not wearing a police uniform, so no one will suspect me when I stand in the crowd.

I only heard a farmer friend with a bald forehead, wearing some mud marks and a blue shirt say: "This old Zhang died a really miserable death, he only submitted his resignation yesterday, and he died this morning." I think it was the contractor of this construction site who did it, he owed us three months' wages, and he must be unwilling to give the old * money, plus the two had a big quarrel yesterday because of the wages. He must have held a grudge and killed Lao Zhang. ”

I frowned and pondered, is this case because of a labor dispute among migrant workers?

Another woman with a bloated figure and a pair of white cotton gloves that had already been black said: "That's not, the big head is notoriously ruthless, a few years ago because of the arrears of wages to migrant workers, others came to collect debts, but he called many people to beat people, do you say that he is a little too much about this." ”

The person next to him asked, "What happened after that?" ”

The woman said: "What else can I do, those migrant workers sued the big head, and the big head went to prison, and finally made up the money for others." In today's society, if you owe money to migrant workers, not to mention beating people, isn't that looking for death? ”

The bystander said: "Then this time it won't be to kill people for the sake of not paying wages, right?" ”

A former bald farmer friend said, "It's possible. ”

And the woman immediately retorted: "What is possible, you don't know the foundation of the big head, there is money." How can it be possible to kill someone for a few thousand dollars, it is impossible and impossible. ”

At this point, many people began to argue about whether this so-called 'big head' killed people.

Of course, this person nicknamed 'Big Head' will definitely be the subject of my investigation. But for the time being, I went to the scene to see what was going on.

The investigation team is still collecting evidence and taking photos in the surrounding area, and the forensic doctor has completed the preliminary autopsy of the body. So I walked over to the corpse and crouched down to examine it. Lao Lu knew my habits, and most of the examinations of corpses were done by himself, rather than listening to the report of the forensic doctor.

Lao Lu stood aside and said to me: "The deceased's name is Zhang Baoxiang, 40 years old this year, single, from Yunyang County, Chongqing City, and has been working in Wanzhou for half a year. ”

I didn't look up, looked at the corpse, hummed, and nodded.

Lao Lu didn't continue, he knew my style of handling the case, if I didn't ask about the death of the deceased myself, it meant that I had to perform an autopsy on the body.

The deceased was prostrate beside the sand, from which there were traces of footprints, falls, and struggles. It seems that the deceased once ran on the sand pile, but because of the attack and struggle, he was seriously injured and fell to the side of the sand pile, and finally died of excessive blood loss due to the severity of the injury.

The deceased was wearing no shoes, but was wearing a pair of thin black cotton socks, which did not smell badly, but smelled of soap. I took off the deceased's socks and found that the soles of his feet were still relatively clean. I can guess that the deceased must have washed his feet at night and put on a pair of clean washed socks before encountering the attack.

But the deceased's shirt and trousers were clearly worn during the day, and I noticed that he was wearing a lot of brown jackets and a woolen vest. And inside the cyan pants, there is also a layer of autumn pants. I didn't think he was anything unusual in this weather, dressed so much, because I judged that this man should be the night watchman at the construction site. Of course, this was proved in the subsequent investigation, and the deceased was a warehouse keeper on the construction site.

I examined the deceased's body spots and the stiffness of the body and deduced that the deceased's time of death was between 1 and 2 a.m. that day. The deceased showed obvious signs of fighting, and his clothes were torn by sharp weapons, mainly on his right arm, indicating that the deceased had used his arm to resist the attack.

The deceased suffered a total of six more serious wounds, including three stab wounds to the back and three stab wounds to the abdomen. Although these wounds are not fatal wounds that can be fatal immediately, they penetrate the body at a great depth, puncture the internal organs, and if the rescue is not timely, it will definitely cause massive bleeding and death.

The murderer is so vicious, is there a grudge against the deceased?

I checked the pockets of the deceased and found that there were six hundred yuan in the pockets on the inside of the jacket, and in the pockets of the trousers, there were some change.

This shows that the purpose of the murderer was by no means to rob and kill. If it's not a robbery, then it's a vendetta or a love killing? It seems that the identity and background of the deceased will also be a focus of my future investigation.

This is the end of the preliminary autopsy of the deceased, which, of course, requires the results of a deeper investigation, as well as the help of forensic comrades.

I stood up and looked around, and found that the bloodstains at the scene were widely distributed, and five meters away from the deceased was a construction site introduction board, which was about three meters long and one meter five high, with some safety matters and a brief introduction to the construction site. Of course, I didn't focus on the content, I focused on the blood splatters on the introductory board.

I walked over to the sign, looked at the blood spatter, and adjusted my posture to strike someone with a dagger to see under what circumstances the blood would be splattered on the board.

According to my judgment at the scene, the blood was not splashed on the victim's body, but the murderer stabbed the deceased and then shook the knife to let the blood spill onto the introduction board. It seems that the murderer at that time was already red-eyed.

About three meters from the body, a pile of hollow bricks was stored, and on the surface of the hollow bricks, there were traces of blood wiping. Apparently the deceased had been standing against this pile of hollow bricks after being stabbed in the back, so there were traces of blood wiping on the surface of the bricks.

I can imagine how frightened and desperate the deceased was at that time. He stood in front of the hollow brick for a while, and then ran desperately to the sand pile in front of him, but he was still chased by the murderer and brutally killed him.

Then look at the sand pile, the blood stains on the sand pile are the most obvious, and the amount of blood shed is also greater than elsewhere. It shows that the murderer was standing on this sand pile and stabbed the deceased three times in the abdomen, causing the deceased to fall off the sand and eventually die.

Of course, judging from the situation at the scene, the deceased and the murderer fled while fighting, because traces of fighting could be seen in many places at the scene, and the footprints on the ground were very messy. However, because of the mixture of ash and sand, gravel and soil on the ground, there are no obvious footprints.

After observing the situation around the deceased, I said to Lao Lu: "It seems that the deceased fought to the death with the gangsters before his death, and the distance of escape was relatively far. It's just that the murderer is chasing after him, and he must put the dead to death. I don't know how much enmity these two people have. Moreover, the deceased's belongings were not lost, which proves that this is not a robbery and murder, but a simple homicide. ”

Lao Lu said: "What you said is not wrong, according to the investigator's investigation, the deceased Zhang Baoxiang was the warehouse manager on the construction site, and he and the murderer fought from the warehouse location until here before they were killed." ”

I said, "Take me to the warehouse." ”

Lao Lu led me to the warehouse. This is a makeshift board room, and the words 'The warehouse is heavy, idlers are not allowed to enter' written in red paint.

One of the panes of the board room was broken, and the glass shards fell to the ground.

Next to the board house, there is a shack. It was built haphazardly with canvas and rain cloth. There was a small bed in the shack, and the bed was very messy, and there was a bad smell of sweat in the shack. Next to the bed are a pair of liberation shoes, a plastic basin and a blue water bottle with a vacuum liner, and a mobile phone on the bed.

Lao Lu said: "This is the residence where Zhang Baoxiang guards the warehouse. ”

I nodded, and I could see that Zhang Baoxiang had fallen asleep before he was killed, because the shape of the quilt was like being violently lifted after it was covered.

So I deduced that Zhang Baoxiang heard the sound of glass breaking in the warehouse, so he immediately got out of bed to check the situation. Because he is a night watchman, he chooses to sleep in kimono so that he can react immediately in case of emergency.

The distance between the shack and the warehouse is less than two meters, as long as Zhang Baoxiang is not completely asleep, he can definitely hear any movement in the warehouse.

Not far from the broken glass window of the warehouse, I found a pair of worn-out brown cotton slippers, and some messy footsteps could be seen on the ground near the cotton slippers. It seems that this pair of slippers was lost here by Zhang Baoxiang, and the reason why he lost his slippers was because he had fought with the murderer in this place, and in the process of fighting, the slippers slipped off.

It can be said that this is the first scene. But this first scene contradicts my previous judgment.

My previous judgment was that the murderer's purpose was to kill for love or vendetta. But according to the current situation, it seems that the murderer broke the window of the warehouse and tried to enter the warehouse in vain to steal, but was discovered by Zhang Baoxiang, so the murderer was fierce for a while and killed Zhang Baoxiang. Perhaps because he killed someone, the murderer was afraid, so he even forgot about the purpose of the theft in the first place, and fled after the murder. Therefore, the warehouse on the construction site only broke the glass, the contents were not stolen, and the money on the deceased was also intact.

The case took a turn here, from the vendetta or love murder that I judged before, to theft and murder. It's just that this theft is not completed, it is just a killing. Then I can infer that the murderer did not intend to kill before, and this must be a murder of passion. And the reason why the murderer wanted to kill Zhang Baoxiang, I guess Zhang Baoxiang recognized the murderer, and the murderer's purpose in killing Zhang Baoxiang was obviously to make Zhang Baoxiang unable to tell him about his theft.

At such a fierce fight scene, except for those blurry shoe prints, no trace of the murderer was found, and I was a little unwilling. I think that in such a wide crime scene, the murderer must leave a trail.

Hard work pays off. I managed to find a broken dark brown plastic basin on the site.

The plastic basin was not seriously broken, on the surface it was trampled on, but when I put the pieces together, a shoe print clearly appeared on the plastic basin.

Judging from the size of the shoe print, I judged that this was a man between 165 cm and 168 cm tall. And this kind of shoe print is the kind of green liberation rubber shoes often worn by construction site workers.

I checked with the workers at the construction site, and they all said that the plastic basin I found was still intact when the work was finished yesterday. Then it can be determined that this plastic basin was trampled on by the murderer wearing liberation rubber shoes when he was struggling to chase Zhang Baoxiang.

Of course, it is impossible for the murderer to leave only such a shoe print at the scene. I reasoned that the two had fought so fiercely, so could the murderer have also been injured?

So I carefully checked the ground at the scene, and on the ground, I could find some dripping blood. And these dripping blood spots were also found at the exit from the construction site. Then this obviously could not have been from the body of the deceased, and I deduced that it was a drop of blood that had fallen from the murderer's injuries.

The blood droplets fell to the ground, splashing about 12 millimeters wide, and according to my inference, they were dripping from a height of about 90 centimeters, which is about the height of dripping from the palm of the hand.

And I noticed that there were footprints on the right side of the blood droplets, which were faintly the same as the footprints on the plastic basin, so I was even more sure that it was the murderer's blood. Of course, it is easy to prove 100% of the time, as long as the comparison is based on the DNA in the blood, and it does not match the DNA of the deceased, then it can be said that it is the blood stains left by the murderer.

And the blood dripping on the left side of the shoe print means that the murderer was injured on the left palm. I suspect that the cause of his injury was that he was cut by his own knife, because when he attacked Zhang Baoxiang violently, if he had not undergone professional training and the handle of the sharp weapon used was not standardized, it was very likely that his hand would slip, causing the palm of his hand to be cut by the blade of the sharp object close to the handle.

So now there are two pieces of evidence left by the murderer.

The rubber shoe prints indicate that the murderer was most likely also a worker on the construction site. Because I heard others talk outside the construction site before, saying that Zhang Baoxiang had a conflict with the contractor of the construction site and had resigned. Perhaps the assailant knew that Zhang Baoxiang had resigned, and thought that the warehouse was unattended, so he came to steal. Who knew that Zhang Baoxiang still did not leave after his resignation, so the two had a conflict. In addition, the murderer insisted on putting Zhang Baoxiang to death, which shows that the murderer and the deceased knew each other. Zhang Baoxiang is a native of Yunyang, and most of the people he knows here are of course workers at the construction site.

The bloodstains on the ground were not compared with the DNA, and I thought they were the bloodstains left by the murderer. Then on this construction site, the person who was scratched by a sharp object on his left palm is the biggest suspect.

After I reported this situation to Lao Luyi, Lao Lu immediately made a decision and immediately checked the left hand of everyone on the construction site.

From the foreman to the mason, dozens of people were examined up and down, although some of them had injuries on their hands, but they were all old wounds, and no new injuries were found that were cut by sharp objects, so the murderer was not so easy for us to find.

After that, the forensic and investigative teams were evacuated. I instructed the medical examiner to carefully identify the deceased's sharp wounds to see what caused them. Moreover, the forensic identification center was asked to make a DNA comparison as soon as possible to see if there were two people's blood DNA at the scene.

In the course of the police doing these jobs, I was not idle. With Lao Lu, we formally met and talked with the contractor of the construction site, the man nicknamed Datou.

Big head, real name Xiong Wenqing, male, 47 years old this year, don't look at the word Wenqing in his name, but he is by no means a literary and artistic youth, but an out-and-out person in the rivers and lakes, who once had a history of being involved in the underworld. Because he used to have a flat head and a round and big head, people in society gave him the nickname of Big Head.

We met Xiong Wenqing on the construction site, because he was also very annoyed that there was a murder on the construction site, and this dead man had a conflict with him yesterday morning.

Xiong Wenqing feels that he is a person with a head and a face, so he hopes that Lao Lu and I will talk to him in private, and don't interrogate him as a criminal suspect.

We agreed to Xiong Wenqing's request, so we went to a restaurant in Longsha Town, ordered a few side dishes, and asked questions in the restaurant's private room.

Xiong Wenqing is wide and fat, and at first glance he is a character with a frame, and his thick left arm is tattooed with a powerful dragon head, which looks very bluffing.

However, at this time, Xiong Wenqing also lost his temper when facing the black-faced old Lu.

Xiong Wenqing took out his Chinese cigarettes and scattered them to us, and Lao Lu said solemnly: "I'm sorry, I don't smoke when I am on official duty. ”

I know that Lao Lu doesn't have this rule, and I can see from Lao Lu's eyes that he doesn't have a good impression of the big head in front of him.

Lao Lu is very sensitive to the intuition of criminals, and he must have sensed that this big man didn't know how many hurtful things he had done in private.

Lao Lu didn't want to smoke anymore, how could I still pick it up, so I also refused. This Xiong Wenqing saw that we didn't smoke, and he was embarrassed to smoke, so he put the cigarette in his pocket. This Xiong Wenqing is indeed an old Jianghu, unlike those stunned greens, whether you smoke it or not, you can order it yourself first.
