Criminal Investigation Notes

When Song Wen was working, he was famous for his hard work. When he arrived here, he immediately entered the working state. He went to the front of the room and habitually rolled up his sleeves until he reached his elbow. He showed a strong and slender forearm and said solemnly, "start work, protect the scene."

Although it is known that the suspect may not be in the house, Fu Linjiang and Lao Jia still rush into the house with guns, then make a gesture of no one, and other talents follow in. The security guard came to check and stepped on the footprints. Xu Yao frowned a little when she came in. It seems that there are not many effective traces left in the room.

The house is located on the sixth floor, which is a constant height. You can take the elevator or walk up with your heart. The windows are locked and there is no sign of invasion from outside. The room type is the current popular house type, a total of about 100 square meters, two rooms and one hall, two bathrooms and one kitchen. The house is transparent from north to south. At this time, the curtain is pulled and the shelter is tight. There was not much furniture in the whole room. Because someone had entered the scene before, some messy footprints were left in the living room. The body was in the bathtub of the slightly larger bathroom.

Song Wen and Fu Linjiang first went to the bathroom, where the property personnel found the corpse.

As soon as they entered the bathroom, they were both stunned. They looked at the scene of the murder, but it was the first time they saw such a strange thing. The narrow bathroom is very clean, without too much blood and traces.

In the bathtub near the corner of the wall, there is a naked headless male corpse with amputated limbs and incomplete body. The body has been divided into several parts. It can be seen that the water has been changed many times, and the blood of the corpse is almost exhausted. The whole body is like meat marinated in water. The smell is not so strong that the body inside can be seen through the translucent water In fact, the trunk of the corpse has been opened, and all the organs and ribs in front of the chest have disappeared, pitifully and unreservedly facing the public.

Lao Jia and Zhu Xiao set up a cordon outside, and Xu Yao began to collect various traces. Lin xiuran first went to the kitchen and looked at the cooking utensils on the stove. There were hedges in the pot and only some broth was left. After a few eyes there, he also entered the bathroom and calmly glanced at the corpse lying in the bathtub.

After that, Lao Jia followed. He looked at the corpse, looked down at a device placed in the corner of the wall, and fiddled with his hands, "this is not a juicer, is it?"

Lin xiuran turned his head and looked at it and said, "if I guess right, his internal organs are crushed by this juicer and washed into the toilet. No wonder downstairs I heard the water flushed all night upstairs. "

Lao Jia looked at his hand and saw that there were still some red and yellow lumps under the device with blade, and there were still some red and sticky tissue residues at the bottom of the device. However, the smell of this thing was much heavier than that of the corpse, giving off a strong odor.

The old Jia, who understood what this thing was, put it down and threw himself at the toilet with a retch. However, Song Wen picked it up and said, "go out and spit. Don't destroy the scene."

Old Jia rushed out with his mouth covered. The kind-hearted Xu Yao handed him a large physical evidence bag. After spitting a few mouthfuls, he calmed down and said, "I haven't seen such a disgusting and abnormal scene in my life."

Lin xiuran said calmly: "is it disgusting? I can't compare with the giant view last time After saying that, he looked back at his calm look. Lu Si Yu, recorded in his book, "you've been an old criminal policeman for many years, but you can't compare with a new one. "

Xu explained," I just don't think he'll order his favorite watermelon juice for the next dinner. "

A word made Lao Jia retch several times.

"This skin condition is not right." Song Wen looks at the corpse in the water. The corpse in the bathtub lost its head and limbs. At this time, there was no soul. Under the white light in the bathroom, it was like a pool of white meat.

Song Wen had more scenes and some basic knowledge. The skin had already rotted. As the blood had been drained out, there was no corpse spot. However, the way the corpse decayed was not the same as the one that was soaked. Most of the bodies they came into contact with in the water were drowned or thrown into the water, which was obviously different.

Lin xiuran looked at the traces on the corpse and calmly analyzed, "the murderer should have changed the water in the pool many times. It may be that the cold and hot alternately, and ice cubes have been used several times."

Old Jia shuddered after hearing this, "it's so disgusting. Do you want to change the water? Is this a goldfish

"Changing water is the same as washing the meat into white meat before boiling the soup, losing blood and making the soup less fishy." Lin xiuran said and looked at it again and made a basic judgment: "the toilet is the main body separation site. The murderer soaked the body in water, then put ice, and then the murderer chopped up the bone and meat, crushed the viscera in the juicer, and part of the ribs stewed in the pressure cooker." After that, he made sure he didn't miss the body

Fu Linjiang asked: "was the head and bone boiled together and thrown away?"

Song Wen said: "you look for it again. It's easier to identify the head. Maybe it hasn't been thrown out yet."

At present, the tenants of this house are unable to contact, so it is more difficult to confirm the identity of the body. Undoubtedly, the head is the key to confirm the identity of the body. In the past, it is difficult to deal with the head, which will be put last by the murderer.With these words, Song Wen goes to the bedroom again. The bed in the bedroom is a bit messy. I don't know whether it's normal or someone has been sleeping before. Zhu Xiao helps pull up the warning line. Cheng Xiaobing, the material evidence, takes out an ultraviolet lamp and looks for blood in the room. Song Wenyi looked up and saw Lu Siyu. At this time, he had already recorded the situation of the bathroom. He turned around and walked around the room with his book. He looked like a student visiting a performance art exhibition. He strolled around the crime scene and stopped.

Song Wenzheng wanted to stop him and tell him not to destroy the scene. However, Lu Si Yu went to the refrigerator, looked up slightly, and then stretched out the hand with gloves and opened the door of the refrigerator freezer.

This is like a completely unconscious action, but Song Wen's eyes follow his eyes, but he is stunned. In the freezer of the double door refrigerator, all the partitions are removed, and there is a frozen head wrapped in plastic wrap.

"The head is here!" Song Wen didn't care about anything else. He got up and walked over. When he heard him speak, Lin xiuran also went to the kitchen.

Lu Si language is indifferent, just like he knew that the head would be here, just open it. When he saw Song Wen and Lin Xiu come over, he naturally leaned aside to give way, and then stretched out his hand to poke a block in another compartment of the refrigerator. It's the same. It's frozen and cold.

After a breath, old Jia passed by and glanced at him and asked, "what is this?"

Lu Si language looked indifferent, poked at the object, felt the softness and said, "it's probably the genitals of the dead."

A word made Lao Jia almost spit out.

After observing the head, Song Wen looks back and looks at the new comrade in his team. At this time, Lu Siyu is lowering his head to record and does not pay attention to his eyes.

Song Wen has seen the scene of the murder countless times, as well as the new forensic medicine or the police. His observation ability is good, and the subtle expression can't hide from his eyes. Ordinary new people, even if they don't lose their manners, can't help but express their fear of facing the corpse from their eyes, movements, tone and subtle expressions.

But in front of this person, or a step-by-step expression, very calm, and even some

That feeling is too subtle. Song Wen doesn't know how to describe that expression.

He doesn't know whether Lushi language has excellent psychological quality or whether it really has a longer reflection arc than others

Or, because I studied French medicine He has been used to these things for a long time?

After the head was found, other investigation work became smooth, more and more clues were found at the scene, some progress was made in material evidence, and the car key, wallet and mobile phone of the deceased were found. A used condom was also found in the garbage can in the bedroom. Zhu Xiao also got more information from the exchange with the property.

Lin xiuran and his assistant first picked up the remains of the corpse with a corpse bag and prepared to transport them back to the new autopsy room of the police station for autopsy before being transported to the cold storage of the funeral home.

When it was almost finished, Lin xiuran made a summary to Song Wen: "it was preliminarily concluded that the time of death was about the day before yesterday. Because the body was once immersed in ice water, the degree of decay was not high. The internal organs of the corpse were completely removed. It is impossible to determine the specific time of death according to the stomach contents. Many cooked bones and meat have not been found, and other information needs further autopsy 。”

Xu Yao added, "due to the entry of the early security personnel, the scene was damaged, and there were not many effective traces found. Most of the blood traces were left in the toilet, so it is impossible to determine whether it is the first scene of the crime." She said a little helpless squat on the ground, thinking for a moment, added, "I suspect the murderer was wearing gloves, and look at the traces, it should be medical rubber gloves." This kind of gloves is relatively thin, which can not only isolate blood stains and fingerprints, but also does not interfere with the feeling of hands, but also brings certain difficulties to the investigation work.

Zhu Xiao explained the identity of the deceased: "the deceased's name is Lin Zhenghua, 39 years old, and he is a senior operation director of an Internet company. I finally got in touch with the tenant who signed the contract with the landlord. According to him, he signed the house plan cheaply for three years, and then transferred it to a friend, namely Lin Zhenghua. He also increased the rent by hundreds every month because the rent was still transferred through him. It has been delivered on time, so the landlord didn't find out that the house had changed its tenant without his knowledge. "

Song Wen bowed his head and said, "what's the family situation of the deceased?"

"The father died, the mother was still there, a wife, and a 15-year-old son."

"Inform the family members to see if they have the time and motive to commit the crime, but they haven't called the police for so many days?" Song Wen slightly frowned, "is the original tenant suspected?"

"The original tenant has been participating in the company's closed group building these days, so he has not answered the phone and has sufficient alibi."

Fu Linjiang came over with a look of regret: "the landlord is unlucky enough. A good house has become a vicious house."

The body hasn't been found, and the investigation work can't be finished. Song Wen raises his head and asks Fu Linjiang, "where do you think the rest of the body will be thrown away?"

Fu Linjiang said: "there is no clue at present. We can only turn around the garbage dump and wasteland nearby, but it is a little difficult..." After stewing, the corpse is more difficult to distinguish. It is no less than looking for a needle in a haystack to find the remains of the stewed corpse nearby.Lu Si language, who has been busy recording beside him, suddenly raised his head and whispered a few words, "blue garbage bag."

This time, the reaction is not slow.

Song Wen just wanted to mention this point. At this time, he took a look at Lu Siyu and said, "there are some blue thickened plastic bags that have not been used up in the kitchen. If there is no accident, the killer wrapped the corpse with this bag. It is the bright blue plastic bag with plastic rope, which should be better distinguished." Then he turned his head and told Fu Linjiang, "Linjiang, call the Bureau and ask them to bring two police dogs together." In this case, police dogs have a much more sensitive sense of smell than humans.

At this time, the staff of the security department came and whispered a few words to Zhu Xiao. After hearing this, Zhu Xiao came to report, "the garage in this community is one car per pole. According to the records, the car of the deceased was parked in the garage at 8:32 the night before yesterday, and never went out again."

What about the video surveillance in Songwen district? Can't monitor the flow of people? "

The security guard was embarrassed when he heard this, but Zhu Xiao felt his nose wrongly. "Song team, you know, this kind of community monitoring is a decoration. There are four entrances in total, and many broken cameras. The blind area is also very large. Even if the monitoring is transferred, it is not of great value."

"What about elevator monitoring?"

"It has been broken for a long time..."

"You have to adjust it according to the rules," Song Wen snorted coldly, and the sarcasm in his voice was hard to hide. "People can't monitor it, but the car is very clear."

Zhu Xiao whispered: "this is not to collect parking fees."

Such is the case in these communities. Once they are able to relate to the income and property fees, they are extremely concerned. For other problems, they are careless. Now this kind of community, the installation is very complete, but because of the low occupancy rate, property fees can not be collected, many staff began to cut corners.

In these words, Lu Si Yu went to Fu Linjiang, and Song Wen turned his head and called him, "Oh, Lu Si language, have you all remembered it?"

Lu Si Yu was suddenly turned back, holding the car key just taken from Fu Linjiang. Fu Linjiang couldn't listen to it any more. He explained to Lu Si Yu: "Song team, you have to let people drink water and breathe when you handle a case, right? He put the cup and bag in the car and went to get it

Song Wen just waved, "go back quickly."

Lu Siyu comes out of the door, stands at the elevator entrance and hesitates for a moment. He still walks down the safe passage to the garage. He takes his water cup and a black backpack from the police car. On the other side of the garage, Xu Yaozheng and Cheng Xiaobing are facing a black SUV. Xu Yao is brushing fingerprints with a small brush, and Cheng Xiaobing is taking photos everywhere. Lu Siyu walks over and learns from it Before Fu Linjiang's address, called sister Xu. Xu Yao turned her head and said hello to him.

Lu Si Yu took back his cup and took a drink. He was not in a hurry to leave, but watched for a while.

It was obviously the victim's car, which was closer to the entrance of the corridor than where they were parked. Lu Si Yu stood beside him for a few minutes, then went to the trunk and opened the trunk of the car to have a look. Cheng Xiaobing is very fond of this new colleague. At this time, he is dazed by Lu Si's language, frowning and concentrating. He is calm and handsome. But there is a wisp of hair, like hair in general standing on the top of the head.

Looking at Lu Siyu, Cheng Xiaobing didn't notice this. He raised his hand to take a picture of Lu Siyu with his forensics camera. The flash of the camera flashed suddenly in the dark garage. Lu Siyu found that he had been secretly photographed. He closed the backup box and walked to the exit. He looked at the monitoring position of the garage, and then turned upstairs.

All kinds of marks have been made on the scene upstairs. According to regulations, the site will be kept for another week to ten days before further cleaning can be carried out. Song Wen was about to finish work and move downstairs when he saw Lu Siyu come up and ask him, "Song team, can I use the microwave oven here to heat up lunch?"

“……” Song Wen blinked and looked at Lu Si Yu. His motto is that rules are dead and people are alive, but even so, he still thinks that it is too unruly.

Song Wen, the criminal police officer who came out of the scene with a packing box, was it the first time that he saw the hot rice beside the pot stewing the corpse? If something is spilled, you're not afraid to destroy the scene? Song Wengang wanted to blame a few words. When he looked up and saw the slight droop of the eyes of the Lushi language, the whole person withered up, like a rabbit with its ears down.

Song Wen suppressed the fire in his heart. He was a police trainee and didn't understand the rules. He turned his wrist up and looked at the time on the lower dial at 12:40. It turned out that he was busy and missed the lunch time. He said to Lu Si Yu: "go to find Zhu Xiao and ask him to contact the property management for you to make the meal hot."

After solving this problem, Song Wen called back to all the people and went downstairs: "everyone is working hard. Have a meal. There are two small restaurants near here. Those who want to order on the Internet come to me. Today is my treat."

Although the scene of the crime is disgusting and bloody, these people have been trained through a lot of hard work. I've seen all the disgusting scenes. As the saying goes, people are iron and rice is steel, so the case can't be broken and the meal can't be ignored.

In the afternoon, we have to start work. We have to walk back to the small hotel. In addition, song team has a rare treat. We all choose to eat. Are we hungry? We line up to order. In this line of work, the conditions are poor and the wages are low. Many of them work harder than this in a year. Sometimes they buy a baked sweet potato and squat on the ground.As soon as the waiting time was almost over, Fu Linjiang, the deputy team leader, came over and said, "well, today, the first day Lu Siyu came, you asked him to make all the records? Not ready to teach? "

Song Wen couldn't see him as a good man. He covered all the people under him like an old hen: "the new man, you must exercise. I find you pay special attention to him."

Fu Linjiang explained: "no, I think it's not easy for other people's children to come here alone. They should take care of them."

Song Wen was angry with him and said, "what kind of child is a 26 year old rich second generation? Can you take care of me

Fu Linjiang looked at Song Wen and said, "Song team, it's good if you don't squeeze us."
