Lao Lu and Liu Sanxun were still sorting out their files, and after I finished reading the case of the bloody handprint, I turned my attention to another case that I thought was very evocative and thoughtful.

The case, which took place in the summer of 2007, was a robbery and homicide that was committed at a farmhouse in a remote area.

The summer heat made me a little drowsy, especially in the afternoon, when I felt like my brain was struck by the uncoordinated coolness created by the air conditioner.

At this point, I need something to stimulate my brain and get it back active. Because I think that as soon as the brain is in a state of strike, it will decline, and my reasoning ability will be severely reduced, which I will not allow.

The phone rang, and on this hot afternoon, I knew that no one would greet me and care about me. Because my social circle is already very narrow, so narrow that there are almost no friends. So I know that this call must have come from Lao Lu.

My inferences have always been accurate.

"Come to Long Beach Town, there's a homicide here, and two people have died." Lao Lu said on the phone in a deep voice.

My brain was activated instantly, and with just these few words from Lao Lu, I began to imagine the possibility of the case. Is it a vendetta? Or is it a love killing? Or kill people and overshop? How was he killed? Shot? Knife killing? Blunt object?

In short, a thousand strange ideas came to mind. It's not a bad thing, it's not how dark and perverted I am. Before learning about the case, assume that the case is a kind of pre-detection warm-up, just like a warm-up before exercising.

Changtan Town is located in the hinterland of the Jiangnan area of Wanzhou District, 23 kilometers away from the main city, and the 318 National Highway and Modaoxi, the largest tributary of the Yangtze River in the district, traverse the town. The town covers an area of 127.8 square kilometers and has jurisdiction over 11 villages and 3 communities with a population of 34,600. As of 2008, the built-up area of the city was 1.22 square kilometers, and the permanent population of the town was 8,904. The town is rich in coal, ore, water conservancy and forestry resources, including Longmenxia Hot Spring and Coal Mining Plant in Chongqing Municipal Scenic Area, and is an important energy town, special agricultural product base and ecological leisure garden in Wanzhou District.

The scene of the murder was two kilometers away from the town of Long Beach, in a farmhouse called "Fu Lai".

Located just off the 318 National Road, this property is not only a farmhouse, but also a small hotel for drivers of long-distance transports.

When I arrived at the scene of the crime, it was already past 3 p.m. This time period makes me feel a little strange. I wondered, could it be that the crime was committed this morning? Because the time I received Lao Lu's call was one o'clock and three minutes at noon. Then it is certain that the time to call the police should not be far from the time when Lao Lu and I contacted him.

Then the alarm time should be around 12:50 noon. In this way, the time when the deceased was found would not be too far from this time. But that's what I'm wondering, did I really find the deceased too late, or was it concealed until now, or was it a crime committed during the day and a murder was reported to the police after it happened?

At this time, the 'Fu Lai' farmhouse has been completely sealed off by the police. At this time, the heat is unbearable, the sun is in the sky, and it is on the side of National Highway 318, and it is not in the town where the residents are concentrated, so there are no onlookers around the farmhouse. It's just that passing vehicles occasionally have people poking their heads out to look around.

This farmhouse is a two-storey house, of course, it is not a simple two-storey house, it still occupies a relatively wide and long area. From the outside, you can see that there are five doors downstairs and five doors upstairs, because the second floor of this house has an aisle. So I speculate that there is one suite inside each door, so the upstairs and downstairs should be the same, so there are ten suites in total. As for how many rooms there are in each suite, you have to go inside to find out.

Outside the hallway in the middle of the two-storey building, there is a sign in bold red font that reads, 'Blessing Comes to the Farmhouse'. On the wall behind the signboard, there is a colorful tile wall, and from the pattern of a part of the tile wall, it can be seen that the whole picture should depict the crane, the old man and the welcome pine.

Outside the building is a courtyard watered with cement, and the sides of the courtyard are all flower terraces, which are now in summer, so the plants in the flower terraces are lush and full of life. But who would have thought that behind this vitality, there was a terrible homicide.

Under the guidance of the police at the scene, I came to the second floor of the farmhouse. Lao Lu was directing the scene investigation upstairs.

"You're here." Lao Lu said as he took off the plastic gloves on his hands, it seemed that he had checked the corpse at the scene before.

I hummed and first asked my question: "When was the body found?" ”

Lao Lu said: "It was found around half past 12 noon. ”

I wiped the sweat from my face and said, "Who found out?" ”

Lao Lu shook the plastic gloves and said, "It was discovered by a little brother who delivered vegetables to the kitchen." He would deliver some fresh vegetables from town to the farmhouse every day, but when he arrived today, he found that the owner and the chef were not there. So he was attacked by the cook's room and found that the cook was dead. So I called the police. When we arrived at the scene, a body was also found in another room on the second floor, which belonged to the owner of the farmhouse. ”

I wondered, "Is there just one owner and one chef in this farmhouse?" ”

Lao Lu said: "I investigated this matter, and the little brother who delivered the food said that usually it is just the two of them, and only when there are many customers or someone makes an appointment for a banquet, they will temporarily call some people to help." But who are the people who came to help, the food delivery brother doesn't know. ”

I nodded and said, "I'll go see the dead." ”

Lao Lu said: "The leftmost house is where the chef was killed, and the rightmost room is where the boss was killed. ”

I first went to the room where the cook was killed.

This room is a single room, and the furnishings in the room are simple, a bed, an old window air conditioner, a 21-inch TV, a table, and two blue plastic chairs.

The cook's body was lying on the ground, wearing only a pair of blue shorts and no shoes on his feet. His body is very fat, and I deduce that this cook, who is less than 170 centimeters, should weigh 180 pounds.

I looked at the bed, which was covered with mats and some blood on the edge of the bed, and a pair of flip-flops was sitting next to the bed.

So I deduced that the chef was suddenly attacked while he was sleeping.

The first thing you need to do to attack someone sleeping in a room is to open the door. So I looked at the door of this room and found that it had been kicked open with a strong kick.

This is an old-fashioned wooden door, and there is no security door installed on the outside, and this lock is also a very old-fashioned bullet lock, so it was kicked open.

Returning to the cook's body, the stiffness and spots of the deceased were analyzed, and the time of the deceased's death was between 3 and 4 a.m. last night.

The deceased had no wounds on his back, but had three slash wounds on his chest, a stab wound on his abdomen, two stab wounds on his right forearm and three stab wounds on his left arm.

From these knife wounds, his fatal wound was a stab wound in the abdomen. The injury was supposed to have injured the internal organs, causing massive bleeding in the body, and eventually causing the victim to die of blood loss.

From the nine wounds on the cook's body, it can be seen that the murderer was very brutal, and every knife was cut down by a dead hand.

From these slashes, it can be analyzed that the one who can achieve this strength is very likely to be a male murderer.

Another place worth my attention at the scene is that there is a silver wrench 20 centimeters in front of the deceased, and there are blood stains on the handle of this wrench, and there are also blood stains on the head of the wrench.

I examined the wrench carefully and was able to determine that the blood stains on the wrench head were from the blow to someone. It appears that the chef fought back after being attacked. As for where the chef took out this wrench, I think the most reasonable explanation is that the chef put it in a convenient place and used it as a self-defense weapon.

So I'm going to make a deduction about the situation.

At around 3 a.m., the murderer kicked open the door of the cook's room with a flashlight in his left hand and a machete in his right hand, and then quickly stabbed the chef in the abdomen.

Because the chef was strong, after being stabbed, he grabbed the wrench next to him, gritted his teeth and fought with the murderer, and in the chaos, he was stabbed several times. Although the chef also hit the murderer, he eventually suffered from the pain of the knife wound and the excessive blood loss from the knife in the abdomen, and finally died due to blood loss.

Then the chef leaves us with a clue that the murderer was wounded by him. This has become the most easily exposed characteristic of the murderer.

The location where the wrench fell from was close to the right of the cook's body, indicating that the chef was fighting the gangsters with his right hand, which is why he had such a deep knife wound on his right forearm, because the killer also wanted to shoot down the weapon in his hand as soon as possible.

Then the chef is using a wrench with his right hand, so obviously the murderer's injuries should be largely on the left. But it's hard to determine where on the left, it could be on the head, it could be on the shoulders, it could be on the arms.

But no matter where the wound is, it is a blunt force wound, and as long as a person with blunt force wound to the left side of the upper body is found, he is likely to be the murderer.

After the analysis of the body, I checked the house again. The chef's cell phone or wallet was not found. So I guess it's a burglary homicide.

Walking out of the chef's room, I walked down the hallway to the boss's room.

The method of entering this room is the same as the previous method of entering the chef's room, which is also to kick the door with your foot. But I can be sure that this man's feet are not as strong as the ones who entered the cook's room before, because of the same door, the same lock, this man kicked about three times before he kicked the door open.

The owner's room is a two-bedroom apartment, this room is obviously renovated, from the furniture to the furnishings are relatively new, and there is a wooden floor on the floor. And on the window glass facing the door, there is still a faded happy word, but this happy word has obviously been torn artificially, just because it was glued too firmly, and some of it was not torn off.

There was no deceased in the living room, but the drawers and cabinets under the TV cabinet in the living room had been opened, and there were obvious signs of someone turning them over.

The deceased was in one of the bedrooms. This bedroom has a large double bed, but there is only one pillow on the bed, and the wall behind the bed appears empty, but there is a protruding iron nail in the wall.

I guess the owner of this room must have been married, but for some reason, they divorced again. I deduced it from the half-torn out word of joy and the nail that used to have the picture on the wall. Of course, the photo that used to hang should be a sweet wedding photo.

The deceased died on the floor next to the bed, he was wearing white shorts and a black vest, barefoot.

There was no blood at the scene, but there were dark brown strangulation marks on the neck of the deceased. This strangulation is not caused by human hands, but by a strong rope.

The time of death of the deceased was also between 3 and 4 a.m. However, in addition to some corpse spots, there are also some scars left by subcutaneous bleeding on the deceased's body.

This scar was left by someone who pressed hard, showing that the owner of the farmhouse died differently from the chef. The chef was killed by a single thug with a machete, while the boss was killed by two or more people working together. That is, someone is responsible for holding the victim's body down, and someone is responsible for strangling his neck with a rope.

Of course, the deceased's mobile phone and wallet were not found at the scene, and the drawers in the bedroom and the secret compartment in the wardrobe were turned upside down, obviously the murderer's purpose was theft.

After inspecting the two crime scenes, I began to make a psychological portrait of the murderer.

The first thing that was determined was that there were more than three murderers.

Then it was determined that the murderer did not have a high level of knowledge and culture. The reason I am so sure is that burglary and robbery are felonies, but the targets chosen by these murderers are not rich and noble, and in this case, it is very likely that they will kill someone, but they will not be able to rob much money, and the gains outweigh the losses.

In the end, it was determined that the murderers were all men.

Outside the corridor, I said to Lao Lu: "The murderer should be a traveler staying here." ”

Lao Lu said: "Why do you say that? ”

I said: "The murderer robbed and murdered the owner and the chef of the farmhouse, and they must have known the environment inside the farmhouse, and they also had to determine how many people were in the farmhouse, whether these people were employees of the farmhouse or the people who stayed there. To understand these things, of course, it is good to stay in this farmhouse. However, I have a hypothesis that these murderers may have really come here to stay here before, but for some unknown reason, they decided to rob the farmhouse. One thing I am sure of is that these people came prepared, that is, they intended to commit robbery. It's just that the final goal changed for some reason, and it was replaced by this farmhouse. ”

Lao Lu snorted and fell into thought.

I knew that Lao Lu had a habit of summarizing and thinking after the scene investigation was completed and the situation of the murder was understood, so I didn't bother him, but went to learn about the environmental facilities of the entire farmhouse.

Of course, I'm on the second floor now, so I'll start the investigation from the side.

I had deduced that the murderer was a guest staying at the hotel, so I immediately checked the remaining three rooms on the second floor.

The structure of these three rooms is the same as that of the farmhouse owner, with two bedrooms, one living room and one bathroom. The difference lies in the layout of the house.

The living room is equipped with a machine and a TV, and there is a cloth sofa next to the wall.

Each of the two bedrooms has two single beds and is furnished in the style of a guesthouse.

The rooms on both sides are tidy and apparently no one has lived in them recently. In the middle room, a pair of pokers was placed messily on the machine table, cigarette butts and soot were everywhere on the ground, and three empty mineral water bottles were also thrown on the ground in a mess.

These things were obviously left behind by the travelers who checked in last night, and these travelers are likely to be the murderers.

I entered the bedroom and found that there were three single beds that had been slept in, so I was sure that there were only three travelers who stayed last night.

Of course, I didn't infer that the travelers were three just by the fact that three beds had been used. It was also inferred from the playing cards that only three people were playing, because judging from the order of the playing cards held, this deck of cards was used to play the landlord. If it is four people, they are likely to turn on the machine to play mahjong.

The three mineral water bottles on the ground can also further prove that there were only three people staying last night.

So could these three be murderers?

The answer I gave, they are the murderers.

The team collected cigarette butts and mineral water bottles from the guest rooms, and they were to extract DNA samples from these items and compare them with DNA databases to find suspects.

I also proposed to Lao Lu a solution idea, that is, to investigate the health centers, small outpatient clinics, and pharmacies in the surrounding towns and villages to see if we could find a person who had suffered blunt force trauma on the left side of his body, and whether he had ever gone to the doctor or bought medicine.

I went downstairs to the farmhouse and checked the downstairs rooms, which were mostly restaurants and chess rooms, and only one room was used for accommodation. But the room used as a lodging is also neat and tidy. It shows that on the day of the incident, only the three travelers were staying at the hotel.

The three travelers chose to stay at this farmhouse, which is two kilometres from town, and I suspect they have transportation. Of course, unless they were prepared to rob the property, they could also walk to the property.

But I'm more sure it's the former.

I braved the sun and walked along National Highway 318 towards Long Beach Town. My aim is to see if there are any surveillance cameras within these two kilometers.

But contrary to expectations, there was not a single surveillance camera on the two-kilometer journey. Of course, if you can find the surveillance footage, then you can find the suspect most directly, which is not my opportunistic approach in the process of detection. Because surveillance video is a vital part of modern detection, it is also the most direct and accurate link.

The on-site survey is basically over, and the next step is the detection link.

There are three directions to detect. The first is to conduct DNA testing on the blood, cigarette butts, and mineral water bottles on the wrenches collected at the scene; the second is to find the injured murderer; The third is to retrieve surveillance footage along National Highway 318 to find suspicious vehicles and pedestrians.

I like to open up ideas, first carefully investigate the identity of the deceased, and see if I can find a possible breakthrough in the case from the identity of the deceased.

I started by researching the chef at the farmhouse.

The chef is a 38-year-old, unmarried, unmarried chef from Hubei, and has been working as a chef at the farmhouse for more than a year.

Feng Yingtian also has a background, that is, he mixed with the underworld when he was young, and he also injured people and went to prison. After I came out, I learned to be a chef and ate with a mouthful of food.

This also confirms why he put a wrench in the house to defend himself, which should be a habit he developed when he was in the underworld.

But this underworld background gave me a new idea. The chef was hacked to death with a knife, and the boss was strangled to death.

Could it be that the chef was hacked to death because he had a grudge against someone?

This idea was immediately rejected by myself, because the reason why the chef was hacked to death by the knife was because the murderer did not kill the chef with the first knife, and the chef began to resist frantically, so the murderer's brutal character was stimulated, and the chef finally died under the knife.

After that, I investigated the background of the owner of the farmhouse.

The owner of the farmhouse is a man from Changtan Town, Wanzhou District, 31 years old this year, divorced, childless, named Xiao Songming.

This Xiao Songming's background is very simple, he once worked on a construction site in other places, earned some money, and the ancestral house accumulated some funds because of the land compensation, so he bought this residential building not far from Long Beach Town and converted it into a farmhouse.

His wife used to be a waitress at a farmhouse, but due to emotional discord, she could only work and fly separately.

However, Xiao Songming is an honest and diligent person, he runs this farmhouse alone, although he is not very rich, but it is not a problem to support himself.

With his not-so-complicated background, it's hard to imagine what vendettas he'll encounter. So this case, as I first characterized, was a burglary and murder case.

The DNA test results are out, but unfortunately, the results are not satisfactory because there is no matching DNA data in the database.

Lao Lu focused the investigation of the case on the injured murderer. Under his leadership, the criminal police went to all the pharmacies, small clinics and health centers in Long Beach Town, but found no matching injuries.

Because the weather was too hot, the outdoor work of the criminal police officers was really hard, the sweat was soaked through the police uniform, dried by the scorching sun, and then soaked with sweat. This repeated time and again left circles of white sweat stains on the police uniform.

After Lao Lu told me about the situation, I thought about it for a while and said, "According to my speculation, the suspect has a vehicle. Then they are likely to drive thousands of other places to see a doctor. But the damage caused by the wrench must not be small, so the murderer should not go too far to seek medical advice. I guess they should go to the front of Aries or *. ”

Lao Lu agreed with my inference, and he said that even if the entire Wanzhou was searched, the injured murderer must be found. Because I know that Lao Lu hates the criminals who rob and kill people. Of course, with a jealous and hateful character like him, as long as he is a criminal, he will kill them all.
