Misty Forest [Criminal Investigation]

After praying for rain, he was full of confidence after posting the notice, because the weather is very hot now. Although it is not early to enter each village, many villagers are still active outside. When they saw him posting the notice, they all surrounded him. He casually asked them if they knew each other. ?The villagers told him that it was too dark to see clearly, and he had to look carefully tomorrow to recognize it.This is in stark contrast to the previous few times when he went to the village to post notices, there was no one around.As long as the news of the dead people being fished in the river spreads, someone's family members who have been missing for many days will always come to ask.

The next day, the phone in the office was quiet all day, and no one came to ask at night. A full 24 hours had passed since the first notice was posted. Qi Yu lit a cigarette irritably, picked up the landline and dialed Dialed internal line: "0"

"Hello." A tired and deep voice came from the microphone.

"Then let me ask if there is any new progress?" Qi Yu asked.

"I'll come down and tell you about it."

Not long after Nianfeng hung up the phone, he brought three people into the office on the first floor with a stack of reports. He walked up to Qiyu and took out a USB flash drive and handed it to Qiyu.Qi Yu took it and plugged it in to the computer, connected to the projector, and asked everyone to pause and listen to the latest situation on the forensic side.

To everyone's surprise, it was neither Nian Feng nor Lin Zhao but Zhu Shitian who came forward with a report to introduce the test results.

The deceased was a male with a height of 1 meters and an estimated weight of about 65KG before death. The autopsy showed no chronic underlying disease characteristics, and the stomach contents were empty. It was inferred that he died more than four hours after eating.The broken nasal bone of the deceased was caused during his lifetime. There was a small amount of sand in the respiratory tract, bilateral lung swelling was obvious, and water emphysema. It was judged that the deceased fell into the water and died of drowning during his lifetime.The mountain bike frame salvaged by Qi Yu and the others matched part of the gap in the deceased's body, and it should be a weight tied to the deceased's body.

The frame was stuck in the river, and the binding was not firm. The body was soaked in water and rotted and swelled and opened the rope, so the bindings fell off the floating surface.

It took less than 10 minutes for Zhu Shitian to cooperate with the photo display in the USB flash drive to introduce all the situation, and Qi Yu asked him if he had anything to add.

"No, don't look at this conclusion. We also worked overtime with four people for a day and a night to make it." Zhu Shitian held the report in his hand and heard the dissatisfaction in Qi Yu's words.

"Who compiled the final report?" Qi Yu pointed to the document in his hand.

"I..." Nian Feng was about to speak, but Qi Yu interrupted Nian Feng's words with a wave of his hand.

"I sorted it out. Is there any problem with the police officer?" Zhu Shitian felt that there was nothing to criticize. He thought that the whole report was concise and the key results were mentioned. Besides, wasn't Nian Feng going to stand up and speak for him.

"I have a lot of questions to ask." Qi Yu nodded, turned over the notebook, and tapped the keyboard to turn up the page.

"The deceased had been soaked in the water for so many days. How did you determine whether the water and sediment in the respiratory tract were poured in or sucked in? Has the composition of the sediment been analyzed? Is it consistent with the composition of the sediment at the place where it was found?"

"What is the material of this frame, how much does it weigh, the deceased's escape is because the bondage is not secure, why is it not secure? The murderer was flustered and didn't tie it properly, or what reason?"

"Is the salvage area the first scene? If not, where is the first scene? Is there any hint from the autopsy?"

"The time of death is ten days ago. This range is too large. Half a month ago is also called ten days ago, and one month ago is also called ten days ago. So is there a relative range?"

Qi Yu raised seven or eight questions in one breath, his voice became higher and higher, and his face became colder and colder. Zhu Shitian frowned and stared at Qi Yu, and the smell of gunpowder in the air between the two was getting higher and higher.

"I'm mainly responsible for the inspection of the frame. Let me add an explanation." Lin Zhao stood up in time and walked to the front to point to the picture on the white wall.

The size of this mountain bike frame is 18, the weight is 4 kg, and it is made of ordinary steel. He has searched according to the vague LOGO on the frame. , because of its high quality and low price, it is deeply loved by the public. There are also physical stores in Lumna for sale. According to the damage and rust, this frame has been abandoned for a long time.Several sections of remaining ropes were found on the frame, and compared with the traces on the body of the deceased, it was confirmed that these ropes were the main tools for binding the deceased.The reason for the broken rope is that during the binding process, the rope passed through the hole on the frame several times, and after being washed underwater for a long time, the rope and the edge of the hole in the frame repeatedly rubbed against it.

A small amount of red brick residue was found during the inspection of the broken rope. The murderer may have worried that the frame was not heavy enough, so he tied bricks to the deceased at the same time. After entering the water, the bricks fell off and the rope loosened. The frame rubbed against several factors, which caused the body to finally get rid of the rope. Surface.

While Lin Zhao was introducing, Bao Siqi quickly searched on the map. Just after Lin Zhao finished speaking, Bao Siqi switched the projection and marked the locations of the three brick factories on the map.

"I just checked. These three brick factories are not large in scale. After the burning, they pile up outside and wait for the customer's car to be loaded. If you want to achieve the purpose of gaining weight, it is definitely not possible to pick up rotten bricks outside, so it is considered that the murderer passed through these few brick factories. One of the brick factories."

"Why did the murderer pass by instead of going there?" Zhu Shitian asked.

Qi Yu didn't even look at him, and then asked Lin Zhao if he had anything else to add. Lin Zhao said no, and Qi Yu said yes, then turned to ask Nian Feng: "Is there anything else?"

"According to the actual temperature measured in the water area where it was discovered, referring to the recent temperature records near the river, and considering the degree of corruption of the corpse, it is estimated that the time of death was ten days ago, not more than two weeks. Let me make the judgment of entering the water before death, and Some of the follow-up work, because it has not been finalized yet, so I didn’t go into details here, and I didn’t consider it thoroughly in this regard.”

"Get to the point." Qi Yu interrupted Nianfeng's apology.

Nianfeng took water samples from the river where the body was found and observed two types of diatoms under a microscope.He tested the lung and stomach samples of the deceased, and found seven or eight different forms of diatoms in the lungs, and three forms of diatoms in the stomach, one of which was not found in the water samples collected at the scene. some.

The slices of the kidney and liver have been partly tested, and there are diatoms that do not belong to the river where they were found. Only after they are all completed can they be used as water samples at the entry point for comparison.

Diatoms are single-celled organisms that exist in waters and can only be seen under a microscope. They have a cell wall made of silicate, which can resist strong acid corrosion, and after entering the human body, they can enter the human body's large circulation through capillaries to reach various organs. .

If the deceased entered the water before he was alive, he was still alive when he choked the first sip of water, and the diatoms entered the lungs and would pass through the capillaries and enter the human circulation. Where they can go depends on the survival time of the deceased.If water was poured into the lungs after death, and the circulation of the human body has stopped, then diatoms can only be detected in the lungs, but not in other organs.

Nianfeng found diatoms in the stomach, liver and kidneys of the deceased, indicating that the deceased's body circulation was normal and alive after entering the water.

There are many types of diatoms, and the diatoms in different waters are not exactly the same. Even in the same river, the types of diatoms in different river sections will be different due to the surrounding ecological environment and geological structure.

"I can go to all the waters to get water, and judge the river that the deceased passed through after death through the diatoms in the water, and the most likely water entry point." Nian Feng said.

"This is a method, but it will not be used for the time being. There are many streams and reservoirs and the drainage canals dug by the villagers for farming. If you are not found at the scene of the first crime, you will be exhausted. Wait. Let's combine the information you gave Analyze the information, and I need your help to find you in the future."

Nian Feng hummed and led a few people out of the office. As soon as Nian Feng left, Wen Bin wanted to say a few words for Nian Feng. Today, the two of them are at war.

"The forensic doctor may be too busy so..."

Before Wen Bin could finish speaking, he was interrupted by Qi Yu: "Turn around and tell Lin Zhao to be on guard against Zhu Shitian, that guy's mind is not right."

Wen Bin scratched his head, a bunch of this and that.

Qi Yu glared at him: "When did I cheat you, don't turn around and Lin Zhao cried for you when he was cheated."

Zhu Shitian's small abacus praying for the rain can be seen very clearly. Regardless of his age, he has been in contact with Lin Zhao. Although Lin Zhao looks like a little frightened rabbit every time he sees him, Lin Zhao works carefully and responsibly. Wen was also taught very carefully by him.He didn't believe that Lin Zhao had tossed about the frame for most of the night, and then came out with such unreasonable words.Lin Zhao is basically responsible for the summary report, and he never misses anything.It is understandable that Zhu Shitian wants to be active and show his performance, but he sorted out the report and removed some things he thought were unimportant. When he introduced it, he was in a mess. I didn't go to the trace inspection, thinking that the trace inspection was not important, so I didn't go to the details of the inspection done by Lin Zhao and Ma Wen.Later, Lin Zhaolai’s supplementary content was justified and well-founded to further illustrate this point...

After listening to what Qi Yu said, Bao Siqi asked: "Then why don't you think that Lin Zhaokeng Zhu Shitian, and didn't tell him that the process deliberately made him make a fool of himself?"

"Little Baozi, what do you mean?" Wen Bin was anxious.

Qi Yu opened his hands and shook: "Okay, okay. Little Baozi's question makes sense. Think about it carefully, starting from the first meal after Zhu Shitian came...Think about it for yourself."

For the first meal, Lin Zhao sent a message asking Wen Bin to help him and Ma Wen buy food, saying that after coming out of the reference room, Zhu Shitian had already bought food for Nian Feng and the two of them finished eating.After Zhu Shitian came, he followed Nian Feng into the anatomy room and refused to let Lin Zhao follow him. Not only did he not let Lin Zhao go, Ma Wen also refused to follow him.What they didn't know was that Qi Yu was stopped twice by Zhu Shitian.In normal work at the scene, Zhu Shitian ordered Ma Wen intentionally or unintentionally, and even Lin Zhao ordered him together. He only listened to Nian Feng...

Thinking about it this way, Zhu Shitian's behavior is justified once and twice, and it is too deliberate every time.

"My own people bring it by themselves, I don't care about anything else, anyway, you four are not allowed to be a monster to me, I am not so easy to bully, after a word, whoever is a monster to my people will get out." Qi Yu saw that everyone was silent The sound gave a warning at the end.

After ten o'clock the next morning, a girl about seventeen or eighteen years old wearing a cotton skirt and plastic sandals walked into the criminal police team. She didn't even knock on the office door, and walked straight to Qu Ruichuan's desk, which was the closest to the door. In front of him, he tapped on the table.
