Police Detective

v7 Chapter 809: Exploring the cause of death (large

"Bai Detective, originally I thought you were just good at logic. I didn't expect that on-site surveys and physical and chemical analysis were so professional. After all, you are a top student." After Sun Jie left, Zhang Suo called Bai Song aside, "You tell me quickly. Said, the situation of this banana water."

"I'm still not sure if it is. I need to see the autopsy results." Bai Song is still more cautious: "I am still unfamiliar with you."

"Don't be afraid of mistakes. Let's assume it is banana water. I also watched the scene and felt that the deceased had been in it for so long. When did he fill him with banana water?" Zhang Suo trusted Bai Song very much.

"There are no signs of fighting at the scene." Bai Song shook his head.

"So?" Zhang Suo touched his neck.

"Zhao Han, what do you think?" Bai Song asked.

"Huh?" Zhao Han was shocked when Bai Song called out, and then said: "From the situation on the scene, I didn't go in and take a closer look, but all said there was no trace of fighting, and the deceased tried to figure it out many times. It should be himself. Take the initiative."

"Drinking it on the initiative?" Zhang Suo glanced at Zhao Han, feeling that he was saying not to talk nonsense.

Zhang Suo knew all the six people in Tianhua City in City A, but he didn't have a deep impression of Zhao Han. He always felt that this young man was dumb and not very clever.

"Yes, I think so too." Bai Song approved Zhao Han's words.

Zhao Han glanced at Baisong, did not continue to speak, but there was a little joy on his face.

"Why did he take the initiative to drink poisoned water?" Zhang Suo immediately changed his attitude. "To put it this way, how is this case determined..."

"I also looked at the situation on the spot. Many bottled liquids are not labeled, including banana water." Bai Song thought for a while: "Zhang Suo, you said, there is a saying that wine is Chen Dexiang, why?"

"Um..." Zhang Suo didn't expect Bai Song to ask, scratching his head, "Is it purer after a long time?"

"Um..." Bai Song has a black line. If this is the case, wouldn't alcohol be the most fragrant: "During the storage process, part of the ethanol is oxidized to become acetaldehyde, and acetaldehyde is further oxidized to form acetic acid, and acetic acid is further combined with ethanol to form acetic acid. Ethyl acetate, also known as ethyl acetate. Ethyl acetate is fragrant, and some blended wines will put some of this, and smell the fragrance. Of course, not only ethyl acetate will be produced in good wines, but also other molecular weights. High esters are very fragrant. And banana water contains ethyl acetate, and things like stupid and xylene are called aromatic hydrocarbons because of their fragrant. The dead are too thirsty and hungry, thinking they are used It's not impossible to take the initiative to drink liquor for disinfection or something.

Moreover, as far as I know, the taste of banana water is similar to liquor. "

"This happened!" Zhang Suo said he hadn't heard of it. "I've learned a lot."

"So the cause of death was my own misunderstanding, right?" Zhao Han interrupted: "Then this is an accidental death?"

"Do not rule out this possibility." Bai Song said: "For example, the deceased took a bath here, and then suddenly received a message from a friend saying that his wife knew that he was here and wanted to come and look for him. In this case, the man must just run away. Find a place to hide, and this may happen."

"Huh?" Zhang Suo looked at Bai Song: "Inspector Bai is young and very experienced..."

"What's the matter..." Bai Song smiled embarrassedly.

"Then, in this situation, the White team, how can it be determined whether it was an accidental death?" Zhao Han asked.

"If that's the case, the mobile phone is usually not left, and even if the mobile phone is not brought, and then picked up by someone else, come here to take a bath, there will always be clothes. The clothes will definitely be locked when you enter this bathhouse, right? Ask this, now check carefully, is there any grid that has been locked these days?"

"Let me ask." Zhang Suo nodded solemnly.

If the clothes are all there, then the situation Bai Song said is possible. Whatever the reason, the deceased had to hide, then hide in the equipment room, and then something went wrong.

This can be checked very quickly. Because people spend the night in this bathing area, the cabinet is not cleaned at night, so the situation Bai Song said is likely to exist.

About twenty minutes later, the front desk, waiter, etc. checked the entire men's bathroom and found that this did not happen.

Because the business was temporarily closed today, and all the guests were taken away and made a simple note, the inventory was very quick.

"Have you checked the female bath?" Bai Song asked.

Just now Zhang Suo told Bai Song about the situation, he heard Bai Song ask this, and vomited: "How could it be in the women's bath?"

Seeing Bai Song's eyes, Zhang Suo helplessly picked up the phone and said, "Women's bath also check it out."

"You are like this, people think I'm abnormal." Zhang Suo sighed.

Ten minutes later, a message was returned, and there was no female bath.

"Then there is a problem." Bai Song said: "The people at the front desk have also asked. It is estimated that no one will remember this man who came in. There are hundreds of guests every day, and the front desk will not look at it. If the man only comes in underwear He will definitely be remembered, so someone must have taken his clothes."

"So, you still have to file the case according to the murder case." Zhang Suo nodded: "That's not my business. I know a few people. If I can help, I need to file the case and follow-up investigation. They separated to do it."

"No hurry, let's see the autopsy results later." Bai Song frowned for the first time.

In fact, many outsiders do not understand the daily experience of the police.

For example, in Jiuhe District, with a population of 1 million, if there are 5 homicides a year, how many abnormal deaths are there?

A conservative estimate is three-digit numbers, even two to three hundred.

In other words, many scenes are likely to be accidents. After the police go there, if they can be 100% sure that it is an accident, death from illness, suicide, etc., it will be handled by the relevant department. As long as all reasonable suspicions cannot be ruled out, the investigation will be carried out according to the homicide case until the final determination.

When Bai Song first started working, he encountered the death of Sun, the one who cheated insurance and committed suicide. The Shi who wrote "I have also drifted for a long time, for ten years, my deep gratitude has been exhausted, my mentor and friends" and then jumped off the building, also committed suicide. In addition, he also encountered a large number of other abnormal deaths, none of which were homicides.

Except for homicides, most of the abnormal deaths are easy to find out, but there are also difficulties, such as this.

Now, Bai Song has begun to lean towards murder, but the evidence is obviously insufficient.

On-site investigation is a big problem. Although Bai Song trusts Sun Jie, he is always uneasy about the absence of East China.

As a painter, Huadong is very attentive, and his trace analysis can be regarded as entering the room.

Moreover, there is not even one camera here, and even the door is not facing the camera here. This actually poses a serious security risk. After this incident, the boss will be unlucky anyway.

But now is not the time to consider this, Wang Liang and Wang Huadong are both drinking, and can't come over.

Liu Shuyuan's on-site surveying ability is also good, better than Bai Song, but he also drank, even Bai Song himself is a little dizzy, which affects his judgment.

"Let's rest first. I don't know how long this anatomy will take." Zhang Suo said: "The case is not our case either. Tomorrow morning, we will wait for the document file to be found out at the station area. Let's take a look at other people's things."

"It won't take that long for anatomy." Bai Song is still a little drunk, and he is full of food. He can't sleep. After thinking about it, "It's our Jie...he is the kind...very special kind. .. The kind that is very fast."

Sure enough, Bai Song quickly received a call from Sun Jie.

"The physical and chemical tests have yielded some results, and the anatomy has made some progress. Let me tell you about the situation." Sun Jie knew that Bai Song was waiting, so what should I say first.

Different information is different in the hands of different people.

"There is a little **** fluid in the esophagus, a large amount of mucus in the trachea and bronchi, which is in a foamy state, and the left and right chest cavities are congested. Pink edema fluid and red blood cells can be seen in a large area of ​​alveoli. The lung interstitium is extensive...

Coagulation and degeneration of superficial slimming of the gastric mucosa, some of which have been...

Ethyl acetate and xylene were detected in the stomach contents, as well as carbon tetrachloride, and acetone was detected in the urine..."

"Does the deceased have mechanical injuries, mechanical suffocation, other poisons, hypoxic suffocation, drowning, other diseases, etc.?" Bai Song asked.

"Not at all. His hand is a bit injured, combined with the situation at the scene, it should be the door smashed." Sun Jie said.

"Approximately how long was the injury on the hand?"

"The injury lasted no more than 12 hours. It was smashed during the day today. It was found at the scene that the deceased had slept with something on the ground. At least he went in yesterday." Sun Jie said.

"That means that the deceased is more familiar with this place. After entering yesterday or the day before yesterday, he knew that someone would come to open the door at intervals, so he was not too nervous at the beginning, but today he can't stand it anymore. He smashed the door desperately and finally became hungry. You can drink this thing if you add it up." Bai Song made an analysis: "According to what you said, it is no doubt that you have drunk banana water."

"Yes, that's the case. The report is estimated to be out tomorrow morning." Sun Jie said, "I'll check it later and leave. I won't be here for the job."

"Niu, are you all in the lead?" Bai Song really admired.

Forensic doctors and other surgeons are actually the same. They also have forensic surgeons, and they are basically the most experienced.

"Who knows what Zhang Suo here told people? People here thought I was an expert from the ministry. I had to bite the bullet, otherwise it would be bad if I missed out and got kicked out." Sun Jie's experience is fairly rich: "Fortunately, I don't shame my life."

"Okay, rest early after you are busy. I'll take a closer look at this case." Bai Song hung up the phone and said to Zhang Suo: "Confirmed, just drank too much banana water."

"I've been doing it for so many years. I have never seen such an evil method of killing." Zhang Suo cursed: "This is the legendary spontaneous self-destruction type? Betting on the probability? I bet that no one will open that in the past few days. Door, and then the dead will drink banana water?"

"Zhang Suo, you are the crux of the problem." Bai Song nodded: "So, now we have to know two things. The first thing is whether the cleaner goes to the equipment room every three days. If not, Why did this time pass several days later. The second thing is that we need to find the boss to determine where they bought this banana water from, and to confirm that the banana water they bought before contains carbon tetrachloride."

"Is there only part of this thing you are talking about?" Zhang Suo asked.

"Yes, this is a very common substance. This is an organic solvent, a volatile liquid, and has a slightly sweet odor of chloroform. It was once widely used. But because it reacts with water above 500 degrees Celsius to produce toxic phosgene , Chlorine and hydrogen chloride gas are very dangerous. Moreover, carbon tetrachloride itself is a thing that has great harm to the ozone layer, and its use is restricted internationally. Our country also restricts this thing. The banana water produced by regular manufacturers should This thing is not included. This is a manifestation of inadequate craftsmanship." Bai Song explained: "This physical and chemical property is very basic, and the university can learn organic chemistry."

"Do you think I looked like I had studied organic chemistry in university?" Zhang Suo was speechless, "Okay, I'll look for someone to investigate according to your ideas."

When encountering a case, I am never afraid of trouble, most afraid of having no ideas.

"It stands to reason that so many people have participated in this case, how can there be no progress at all now?" Bai Song was somewhat confused.

"White detective, our police force here is not what you think..." Zhang Suo sighed: "Blue City is not bad, the capital city, but your school still has criminal officials, how many are willing to go back to Gansu Province? ?"

"I don’t agree with what you said, Zhang Suo. Let’s not mention you. I’ll just talk about the criminal policemen I met at the scene and the ones I met in the hospital. You can see that they are all professional after contact. ."

"Um..." Zhang Suo was found modestly and was a little puzzled: "Indeed, the clue feedback is a bit slow. I called to ask. By the way, look at what you said and find someone to check it."

Zhang Suo can also be regarded as an outsider in this case, and Bai Song and others are outsiders to outsiders, so Bai Song is worried that they may not be shared with information ~lightnovelpub.net~ If this is the case, it will be very unfavorable for handling the case.

Almost ten minutes later, Zhang Suo got feedback, and the case is indeed stuck now.

Because the matter was too strange, the Criminal Police Team has already started investigating the homicide case. Three or four waves of people have been sent to the scene to conduct on-site investigations, and the surveillance in a large area nearby is also being checked.

"Didn't the station district police station take charge of the case at first? The criminal police team is now in charge?" Bai Song said, "It looks like it is indeed a homicide case."

"That's it." Zhang Suo said.

"The question is, why did the people at the police station go?" Bai Song asked.

"Huh?" Zhang Suo suddenly reacted: "Damn, are they carrying me and arresting the fugitive?"

"Let's go, go to their office." Bai Song smiled suddenly: "I feel that this case is in the wrong direction~"

(I have an illusion that I can add more tomorrow)
