Long Zihan rubbed the corners of his forehead and said: "My mother really doesn't give me peace of mind the older she gets, she left suddenly, and then, she didn't contact her family for seven consecutive days, and she came back suddenly, which made me nervous." ”

"Isn't the second uncle on the side? You're still so worried. ”

Long Zihan said: "They have something to hide from me. ”

Long Jiaqi looked stunned, and suddenly understood his intentions.

He asked, "So, what do you think I or my dad might know?"

Long Zihan nodded and asked, "Do you know?"

Before, they said that when they went on a trip, he was considered to be his mother's willfulness.

But he lost contact for seven days for no reason, which made him feel that something must be wrong.

Long Jiaqi shook his head and said, "My dad and I also found out when they suddenly decided to leave. ”

Long Zihan frowned slightly, sighed, and said, "Maybe I'm thinking too much." ”

After that, he looked at his watch and said, "Yiren and I have to go, and we have to go to work." ”

Long Jiaqi nodded and said, "Okay, then I won't send it, you guys should pay attention to safety when driving on the road." ”

After saying goodbye, Long Zihan and Chu Yiren returned to the police station.

After Long Zihan and Chu Yiren left, Long Jiaqi picked up the phone and broadcast a set of numbers.

After the phone was connected, Long Jiaqi said: "He just came, yes, he asked." ”

After listening quietly, Long Jiaqi asked again: "Second aunt, how long can you be confident that you can hide from him?"

......

returned to the police station, but before Long Zihan could meet the office, he was stopped by a sudden case.

When the fishermen went out to sea to fish, a corpse was recovered, and several people were shocked to report the case.

Seeing the appearance of the deceased, Long Zihan said: "There are often people in this area who organize free diving, and the deceased is wearing a diving suit and carrying an oxygen cylinder, so he should be a diving enthusiast. ”

Mo Bei asked: "The underwater pressure is very strong, could the deceased burst his lungs, or the decompression was too fast?"

"No, it won't. ”

Chu Yi said with certainty: "If the death is caused by pressure or gas, the blood vessels in the fundus of the deceased will spasm and rise too fast, and the air bubbles in the body will cause the capillaries to rupture. ”

Long Zihan said: "These dead people obviously didn't. ”

Chu Yiren said while inspecting: "On the right cheek of the deceased, there is a contusion caused before death. There were no serious sexual trauma on the body, which at least indicates that the deceased was not hit by the boat. Looking at the corpse is like drowning, and the time of death should be about 30 hours. ”

Mo Bei asked suspiciously: "Can diving enthusiasts dive with oxygen cylinders on their backs, can they still be drowned?"

Wang Xiaoguang said: "There are two possibilities, one is that the underwater oxygen tank is out of gas and has no time to rise to the surface. ”

Long Zihan shook the oxygen tank and said, "There is still a lot of oxygen in it." ”

Wang Xiaoguang said: "That's the second type, the deceased choked underwater and died in a coma. ”

Chu Yi said, "You don't say the same thing. ”

"Huh?"

The Chuyi people reminded: "Gas reasons. ”

Wang Xiaoguang suddenly realized: "Oxygen poisoning and nitrogen drunkenness. ”

"What are you talking about?" asked Mo Bei, puzzled.

"The air we breathe in is mainly composed of nitrogen, oxygen, and a small amount of carbon dioxide. However, once the partial pressure of oxygen exceeds 1.6, the person may exhibit oxygen poisoning. ”

Long Zihan asked, "What about the other one?"

Wang Xiaoguang said: "Nitrogen is an inert gas, which can make divers feel 'nitrogen drunk' at a certain depth of water. Drunken diving can lead people astray by losing the ability to judge situations and react correctly. ”

At this time, Chu Yiren took the oxygen cylinder in Long Zihan's hand and said, "Actually, there is another possibility, which is carbon monoxide." Sometimes, the air compressor can burn the oil, producing carbon monoxide that contaminates the gas that is pressed into the cylinder. ”

At this time, Erin came over and said, "The confession is ready, but nothing special. The identity of the deceased will have to wait until he goes back to find out. ”

Long Zihan nodded and said, "Okay, since there are no clues, let's go back and talk about it......"

Police station, conference room.

Chu Yiren said: "According to the pubic symphysis of the deceased, the symphysis of the symphysis has basically disappeared, and the ossified nodules have fused to form an ossified form, and the age of the deceased should be about 23 years old. We took blood samples from the veins, arteries and ventricles of the deceased, and the test results for all commonly used drugs and metabolic waste products were all negative, and the hydroxyhaemin level was normal. ”

Long Zihan nodded and motioned for her to continue.

"After examination, it was confirmed that there was no problem with the oxygen in the oxygen tank. The pleural effusion of the deceased is also sufficient to show that the deceased did not die of diving, but of drowning, but the fluid in the lungs of the deceased is consistent with the composition of seawater. ”

Zhao Xiaohu said in surprise: "This is strange, could it be said that the deceased was drowned in the sea, and the diving equipment on the murderous gloves was thrown into the sea." ”

As soon as these words came out, everyone's eyes looked at him.

Being a little hairy by everyone, Zhao Xiaohu asked, "What's wrong?"

Erin patted Zhao Xiaohu on the shoulder and said, "Okay, if it continues to develop like this, you will soon get rid of the burden of 'all muscles in your head'." ”

Zhao Xiaohu scratched his head and said with some embarrassment: "I'll just say it casually, and I don't know if it's reliable." ”

"It's reliable, because we found a posthumous strangulation mark on the deceased's back," said the Chuyi. And this strangulation mark was caused by the back frame attached to the gas cylinder on the deceased's body. Also, I forgot to mention that the time of death was around one o'clock in the morning two days ago. ”

Erin frowned and asked, "What are the dead and murderers doing at sea at one o'clock in the morning?"

It's pitch black, two people are going out to sea with a boat? What are you doing? Are you killing yourself? This is not logical.

Liu Yuanheng said: "The first thing we need now is to find the identity of the deceased, otherwise we really can't find anything." ”

Long Zihan said: "The sport of diving has only come in the past two years, and there are not many people playing locally, but there are small groups, and they will not be ordinary bosses." Send someone to find these people, and there will always be someone who will recognize the dead. ”

Everyone responded in unison, "Yes." ”

After the meeting ended, everyone followed the instructions and received their respective tasks to find the target and the identity of the deceased.

Long Zihan returned to the office, and was about to do something when the phone rang.

Long Zihan picked up the phone and said politely and habitually: "Hello, this is the police station, I am Long Zihan." ”

The other end of the phone said: "Long Zihan, I'm Cheng Yi." ”

Long Zihan was slightly stunned, and then said unhurriedly: "Mayor Cheng, you will never call me for a trivial matter. (To be continued.) )
