Criminal Investigation Notes

"I thought it was a walking dead, but I didn't expect it to be the return of the mummies." Song Wen settled the witness and walked to the corpse. He took out his mobile phone and struck a light. Under the white light, the white powder on those corpses Reflecting a little bit of light, Song Wen knelt down and took a look, "What was originally stored in this pit? Is it poisonous? You must be careful."

Lin Xiuran said: "I've checked it out, and it's industrial salt, which is nitrite." Salt can quickly make the moisture in the meat disappear, no wonder it will form a corpse.

Song Wen took a flashlight and frowned around him and asked, "Isn't nitrite going to be fatal after eating it? This dangerous product is left in this old factory and no one handles it?"

Lin Xiuran sighed and said, "This factory has ceased production a long time ago. I am afraid that the responsible person will not be found. The industrial salt is heavy and worthless, and the workers are reluctant to move."

"I will make an application later, and see if we can deal with it specially." Song Wen finished his thoughts: "That is, after this brother was murdered, the dead body was abandoned here..."

Lin Xiuran pointed to the bags stacked in the corner on the side. Among them, there were a few empty bags marked with nitrite: "This may have been empty. It should be the suspect who killed the people. He poured out the industrial salt and covered it. Corpse. Industrial salt absorbs the moisture in the body, corrodes the skin, and prevents the corpse from decay. In terms of time, it should be winter or spring. At a lower temperature, a dry corpse is formed."

Song Wen asked: "Can the victim be identified now?"

Lin Xiuran shook his head and fiddled with the corpse: "The face has long been unrecognizable. After the murderer abandoned the corpse here, he took off the corpse's clothes and sprinkled it with industrial salt, so what we know is what we see now. There are so many others, it is estimated that they will be known after an autopsy."

The old factory, the naked, unnamed corpse of the unidentified male corpse, and the inability to identify the deceased, this mystery lies before their eyes.Song Wen made a judgment: "Then let's go back and find the missing men within a year."

Seeing that the initial inspection here is almost done, Lu Siyu stood up and took the on-site recording. He raised his head and looked around. It was quiet and remote. The light was not very bright on his face and refracted on the lens. There was a light, he lowered his head not knowing what he was thinking, took off his gloves, and moved his slender fingers.

Song Wen turned his head and said to Lin Xiuran, "What? Let's take this'brother bacon' back first."

When it was time for physical work again, Lin Xiuran went to the car to get the body bag.Lu Siyu took two steps back automatically without causing them trouble.Song Wen, Lin Xiuran and two other assistant policemen were careful not to get the powder on their bodies. Finally, they worked together and put the body into the bag.

Xiaocheng has already taken a lot of photos of the scene, and other physical evidence trace inspections have also collected the traces of the scene. There are often bands here to rehearse, so there are many traces on the ground, and the time of the corpse was several months ago. Many clues are not available.The little girl was frowning there, and Lu Siyu walked over and asked her, "Is the luminamine taken?"

Luminol, also known as luminol, can chemically react with human blood and sperm spots, showing a fluorescent color in the dark.It is especially obvious under ultraviolet light, and it is often used by forensic medicine and physical evidence to find blood stains.

"I brought it, but it's so big..." Cheng Xiaobing frowned. They don't know the route the suspect has taken now. In such a big place, dozens of bottles of luminol are not enough to spray.She also thought of testing blood traces just now, but because it is too big to start.

Lu Siyu stretched out his hand and said, "Give me a bottle."

Cheng Xiaobing went to find a bottle for him, and then gave him a UV lamp.She looked at Lu Siyu curiously, not knowing how he was going to use this thing.Lu Siyu looked back at the terrain here, and chose the entrance on the left. Then he wandered all the way, walking very slowly, spraying twice with something in his hand from time to time.

Outside the factory at this time, Lin Xiuran and Song Wen joined forces to carry the body onto the corpse truck.Song Wendao: "I thought you would cooperate with Xu Changying to investigate Xia's unknown case. Why are you free to come over today?"

Lin Xiuran said, "That's just Gu Ju's casual comment. Xu Changying brought her own forensic doctor. She was a woman. She arrived yesterday afternoon, and then he passed Xia's unknown bones. He said it was a few days ago. An autopsy report."

Song Wen chuckled. Lin Xiuran had already prepared the report in a rush. Xu Changying seemed to want to check it again: "No one from the provincial bureau can believe it."

"Naturally, it's a big case after all, and there is no room for error. For them, the safest way is to find someone they believe to check again." Lin Xiuran said and took off his gloves: "People who have been dead for more than ten years There are only dry bones, and it has been soaked for a long time. The autopsy is very difficult. I am happy and free. By the way, do you know that they want to transfer people from the city bureau?"

Song Wen shook his head: "I haven't heard of it, and I didn't pay attention to this." In the past few days, Gu Ju asked him to rest, and he really took a rest for two days.Yesterday he packed up his things and set up his desktop computer in Lu Siyu's study room, and played a few games to relax.

Lin Xiuran and him gossiping: "I heard that the manpower brought is not enough. I will select people from the municipal bureau to join the task force. When the case is over, it may be transferred directly to the provincial bureau."

Song Wen replied casually: "That's pretty flat. I'm afraid there are many people who want to rush to it, right?"

"Yeah, I heard that Zhao Li of the second team seemed to have taken the initiative to ask for help. Then, it was a direct tragedy." Lin Xiuran said again, "Ordinary people, people from the provincial bureau may not be admired." Then he wanted to say again. Stopped, but seemed to feel that Song Wen wasn't loyal enough not to remind him, so he started talking, "Guess who the surname Xu fell in love with?"

When Song Wen read this, he meant something. Thinking of Lu Siyu coming out of the meeting room and faltering before, an ominous premonition suddenly appeared in his heart: "It won't be... the little ancestor in my team, right? ?"

Lin Xiuran nodded, slammed into the factory building, and then made a silent gesture to signal Song Wen not to be heard.

Song Wen cursed, "Digging the foot of the wall and digging on the head of the young man!" He didn't care about the case when he was seized. It was a frustration in the workplace. He originally thought that living in Lu Siyu's home would be a step closer. , I didn't expect to kill a surnamed Xu halfway.Lu Siyu is not short of money, and he has no interest in names. If he talks about hobbies, he only has to investigate cases. Especially for some cases, he has a weird perseverance. If Xu Changying uses this to seduce him, he will abduct him if he is not all people. Up.

Lin Xiuran saw Song Wen's reaction and asked in a low voice, "Didn't Lu Siyu tell you?"

Song Wen narrowed his eyes and straightened out the whole thing: "He didn't tell me, maybe he is still hesitating. I will go back to talk to him. Thanks to Brother Lin." Then he took out his phone and checked the time. It's almost nine o'clock, and this torment is estimated to be more than ten o'clock when I go back. "Let's go and see first. Come here first, or else you will have to go back all night for an autopsy."

The two closed the back door of the corpse truck and returned to the factory building. Song Wen still opened the cordon and walked in and asked, "How is everyone doing?"

Lu Siyu had been busy for a long time. At this moment, he spoke, and a clear voice sounded behind Song Wen: "Song Team, turn off the lights."

Song Wen was puzzled and looked back at Lu Siyu. The man was looking at him sideways, as if waiting for his action. Song Wen looked up and saw that the switches for the searchlights were on his side. Not far away, he reached out and pressed the junction box that was pulled out.

The entire factory building was suddenly shrouded in darkness, with only a little moonlight projecting in from the window.

The air suddenly became quiet and almost solidified, and then a purple light emerged. It was Lu Siyu who lighted the purple light in his hand. Everyone hurried to see, everything was like magic. Wherever the purple light went, a patch of mottle appeared. Fluorescent colors.In this pitch-black factory building, it was unexpectedly strange and beautiful, like a dream.

As the light moved, a fluorescent "blood path" appeared, with half a bloody palmprint on the edge of the industrial salt pit.

"Ah!" Although it was just an incomplete palm print.But it is also extremely valuable.Cheng Xiaobing took a few steps, wanting to see more clearly.Song Wen suddenly pulled her arm, "Be careful!"

Cheng Xiaobing lowered her head to see clearly. It turned out that she had already walked to the edge of the salt pit. If Song Wen did not pull him just now, she would fall into the salt pit. Cheng Xiaobing was afraid after a while, so she squatted down and crawled carefully. Into the pit.After taking a few photos, the palm prints were left with gloves, and you can see that the base of the middle finger of the right hand is thicker than the other fingers.

Lu Siyu knelt down and stared: "The suspect's right middle finger may be wearing a ring. This ring seems to be not too small..."

Cheng Xiaobing was a little curious and asked, "Lu Siyu, how do you know where there will be blood stains?"

The entire plant is huge, and finding blood here is no less than finding a needle in a haystack.

"The person throwing the corpse should be very familiar with this place. His original plan was to throw the corpse into this pit. So after he entered, he didn't take a detour and went straight here. Moreover, the victim was tall and the body was thrown. The shape is relatively small compared to him, so the corpse thrower rested here on the platform on the right, stopped walking, and threw the corpse into the pit with his back on his back.” After explaining this, Lu Siyu took a photo next to him again. There were also some blood stains on the bag where the industrial salt was placed. “He searched for chemicals there, threw a few bags, buried the corpse, then took away the corpse’s clothes, and wiped away some blood stains with the clothes.” So , Some blood stains are just a vague ball, not very clear.

"The movement is slow and relatively short." Cheng Xiaobing pursed his lips and asked, "So, isn't it the young man who has been here to throw the body?"

Lu Siyu shook his head and turned his head to think for a while: "Understand the layout here and know where the chemicals are stored. I think this person is more likely to be someone who has worked here that year. Maybe he is older, so Physical strength is a little lacking."

Song Wen nodded in agreement, "He just knows that this is an abandoned factory, and doesn't know that it has become a gathering place for young people. If he knew that there would be so many people coming and going, he would not put the body here. The murderer dared to use this as a place to throw the corpse. He must feel that this place is secret enough, and that he completely destroyed the corpse, and feels that no one will be able to find out the identity of the dead.

Had it not been for those underground bands gathering here, this corpse would not have been discovered in ten or eight years.Song Wen thought for a while and said, "I think there is a possibility that the time to throw the corpse is before those underground bands use this place."

Lin Xiuran also said: "I just asked those young people, they started using this place about five months ago, so the time of death, the time of corpse throwing may be earlier than they found here, and this time is also consistent with the condition of the corpse. Said that the deceased died at least five to six months ago."
