I am a super cop

Chapter 531 High fever of 43 degrees?
"Junior Brother Gu." Lu Weiwei looked at his feet and reminded him intentionally.

"I know." Gu Chen nodded, knowing that something was dropped just now, so he squatted down and picked up the object on the ground.

At this time, Lu Weiwei also rushed to his side. The object in Gu Chen's hand was a thermometer, which made them both very curious.

Gu Chen searched for other clues while flipping through the items in the wallet.

In the black wallet, apart from some cash and receipts, this thermometer aroused Gu Chen's curiosity.

"This thermometer...does Dr. Liu carry it with him?" Lu Weiwei asked.

Gu Chen nodded slightly: "Almost, but why wasn't the cash in the wallet taken away? Could it be that the murderer accidentally left it behind while moving the corpse?"

"I guess it's the same." As Lu Weiwei said, she took the thermometer from Gu Chen and held it in front of her for observation.

As for the profession of a doctor, it is normal to carry a thermometer with you, so that it is convenient to measure the patient's temperature.

But it is rare to put the thermometer in the wallet. It can be seen that Dr. Liu usually has a little habit of carrying the thermometer with him.

Lu Weiwei was holding the thermometer and was about to shake it casually, but at this moment, Gu Chen's eyes froze suddenly, and he grabbed Lu Weiwei's right hand.

"What's wrong?" Lu Weiwei looked at Gu Chen curiously.

"something wrong with."

"Ask... a question?" Lu Weiwei looked at the thermometer in her hand and couldn't help asking, "What's wrong with this thermometer?"

"It's the temperature." Gu Chen said.

Lu Weiwei froze for a moment, then frowned slightly, and began to observe the temperature of the thermometer according to Gu Chen's prompt.

Gu Chen casually took the thermometer from Lu Weiwei's hand, held it in his hand to observe closely, and then directly reported the temperature of the thermometer at the moment.

"This thermometer is obviously abnormal. Look, its temperature shows 43 degrees."

"My God, really!" Lu Weiwei frowned, and seeing the current temperature of the thermometer, she couldn't help asking twice: "Will the scale of this thermometer not drop? Why is it still at 43 degrees?" look."

"Senior Sister Lu, you haven't learned physics well, have you?" Gu Chen also couldn't help teasing when Lu Weiwei asked a question.

Lu Weiwei blushed, and said with embarrassment: "Maybe I have learned the relevant knowledge before, but how many years have passed, how can I still remember it now?"

Looking at Gu Chen, Lu Weiwei smiled again and said, "I'm not your Junior Brother Gu. With such a good memory, won't the temperature on the thermometer drop? It has remained at 43 degrees for so long."

"Because the main working substance of the thermometer is mercury." Gu Chen said.

"This... I also know this. When I was young, I remember buying one at home, and I also said in physics class that the main working substance of the thermometer is indeed mercury, but..."

"But when the thermometer leaves the body, the mercury will record the highest temperature ever measured, and will not return to the bottom of the tube."

Before Lu Weiwei could finish speaking, Gu Chen answered directly for her.

Lu Weiwei was stunned for a while, and asked Gu Chen weakly: "Is...is it like this? Will you not return it?"

"Senior Sister Lu." Gu Chen held the thermometer directly in front of her and said, "You may have forgotten that when the thermometer touches the human body, the mercury in the tube will expand and rise when heated."

"And when the mercury's temperature is in equilibrium with the body's body temperature, the mercury stops expanding and reaches a stable temperature."

"Yes, that's right." Lu Weiwei nodded silently, and said again: "Isn't this always the case when measuring body temperature? The measured body temperature is often the highest value of the human body temperature. I remember it was clamped under the arm."

"That's right." Gu Chen showed the scale of the thermometer to Lu Weiwei, and then explained: "But Senior Sister Lu, you may have forgotten that after measuring for a certain period of time, pull the thermometer away from the body, the mercury will shrink when it is cold, and the narrow part of the thermometer will will automatically disconnect."

"And the mercury that has risen into the mercury column will not retreat, but stay in place, so that people can judge the temperature of the human body according to the height of the mercury."

"After using the thermometer, you must shake the thermometer down vigorously to make the mercury in the mercury column slide down into the vacuole, so that it will not affect the next use."

Under Gu Chen's rhetoric, Lu Weiwei nodded her head like a schoolboy listening seriously.

"I know Junior Brother Gu, what you mean is that if you don't shake the thermometer vigorously, the temperature in the thermometer will always maintain the temperature at the last measurement, right?" Lu Weiwei asked.

Gu Chen nodded: "That's what it means."

"But." Lu Weiwei looked at the exaggerated number of 43 degrees on the thermometer, and couldn't help jokingly said: "But Junior Brother Gu, have you ever thought about who can live well with a high fever of 43 degrees? Could it be the last time Dr. Liu saw a doctor old lady?"

"If that's the case, isn't the old lady dead? Can she still live? This high fever is too terrifying."

Of course Lu Weiwei knew that the normal temperature of the human body is usually around 37 degrees, and a high fever of [-] degrees is already a very fatal thing.

Can you have a high fever of 43 degrees?Lu Weiwei had never seen such a person.

After thinking quietly for a few seconds, Gu Chen said, "Why don't you ask Police Officer He to contact the patient's home to see what happened that night and whether the patient had a fever."

"I think it's okay, then I'll call Lao Wang." Lu Weiwei didn't think much, and directly took out her phone and started contacting Police Officer Wang.

Gu Chen continued to search around the scene.

Not long after, Lu Weiwei received a call back from Police Officer Wang. After communicating with each other, Lu Weiwei hung up the phone.

"Junior Brother Gu, I have already asked the patient. The patient had a slight fever that night, about 39 degrees. It was measured by Dr. Liu."

"Besides, I also roughly explained the situation on our side to them."

Listening to Lu Weiwei's words, Gu Chen felt even more curious, and shook his head involuntarily.

"No, a fever of 39 degrees, why does the thermometer show 43 degrees?"

"If you look at the normal situation, after taking the temperature, the doctor usually shakes it vigorously to keep the thermometer in place."

"But Dr. Liu measured the old lady's temperature was 39 degrees, and this was the last patient Dr. Liu saw, after which Dr. Liu disappeared."

"That's right, the old lady is indeed the last patient Dr. Liu saw." Lu Weiwei also nodded fiercely. After hesitating again and again, Lu Weiwei asked Gu Chen weakly:

"Junior Brother Gu, could it be... Dr. Liu went to see a doctor for other patients after seeing the old lady and measuring her body temperature?"

"No." Gu Chen directly refuted Lu Weiwei's words: "Think about it, based on the situation at the time, Dr. Liu did indeed leave on a battery car after seeing the doctor."

"At the same time, within a few minutes, the car passed by the patient's house, and five or six minutes later, the car accident happened."

"From the bloodstains we found at the scene over there just now, and the battery car, we can conclude that this car accident was inevitable."

"And I have already extracted relevant bloodstains from the scene. If it is as expected, I will bring it to the technical department for identification. The bloodstains should be Dr. Liu's."

"Yes." Gu Chenyi said it, and Lu Weiwei regained consciousness from the reasoning just now, and then said: "Indeed, if the blood on the road belongs to Dr. Liu, it means that Dr. Liu came out of the patient's house. Never treated anyone else again."

"So, according to Dr. Liu's temperature measurement without using the thermometer, the temperature of the thermometer should be 39 degrees, not the exaggerated 43 degrees."

Gu Chen nodded: "You're right, so this temperature is absolutely abnormal, there should be other reasons."

Thinking of this, Gu Chen suddenly smelled a faint smell of gasoline.

It didn't seem to have much reaction at first, but now I feel more and more that the smell of gasoline is around.

"What's the matter?" Seeing Gu Chen sniffing, Lu Weiwei couldn't help asking him.

Gu Chen didn't answer, but turned his eyes to the black wallet in his hand.

He immediately brought the wallet in front of him, and after looking around a few times, he found that the corner of the black wallet was obviously scorched.

Put it on the tip of your nose and sniff it, there is indeed a smell of gasoline.

"That's the smell." Gu Chen was overjoyed, snapped his fingers and said, "I see, I know what happened to the thermometer."

Seeing that Gu Chen was overly excited, it felt like winning the lottery, so Lu Weiwei hurriedly asked him, "Junior Brother Gu, do you know what's going on?"

"It's fire, it's fire, Senior Sister Lu, I finally know why Gao Chuanfeng and I made mistakes in judgment, and this is the reason."

Gu Chen walked back and forth twice in front of Lu Weiwei, with the wallet in his left hand and the thermometer in his right. He felt that these two things were the key clues he had found.

"It's not that you'll wait." Lu Weiwei was dumbfounded by Gu Chen's words, she quickly scratched her head, and after she calmed down, she asked again: "You mean, the body was roasted by fire, right?"

"Yes, that's it." Gu Chen brought the black wallet in front of Lu Weiwei: "Senior Sister Lu, do you find anything in this location of the black wallet?"

"Uh! It seems to be burnt, the leather surface is a little burnt."

"Smell it again." Gu Chen moved the black wallet closer.

Lu Weiwei stretched her neck and sniffed: "Huh? Why does it smell like gasoline? Could it be baked by gasoline?"

Gu Chen smiled, first put the wallet into a forensic bag, and then put the thermometer in another forensic bag, and then asked: "Now you should understand what's going on, right?"

"Understood." Lu Weiwei said with a smile, "The murderer roasted the corpse with gasoline, which accelerated the rate of decay."

"This can also explain why Junior Brother Gu and Gao Chuanfeng both judged that the time of death of the deceased was about a week, because you judged according to the normal decay rate of the corpse."

"That's right, that's why there was a conflict with the clues Officer He got." Gu Chen said.

Lu Weiwei shook her head with a smile: "I mean, you both studied under Fayi Liu, how could you make such a big mistake?"

"Because the murderer deliberately roasted the corpse, the murderer made a smart move on the time of death in order to cause trouble for the police and prevent the police from finding out the time of Dr. Liu's death."

"And the murderer took advantage of this to abandon the baked corpse of Dr. Liu in the wilderness and separate it from the first scene of the crime."

"In this way, it must be even more difficult for our police to investigate who the murderer is."

"And the temperature of the thermometer is as high as 43 degrees, which can also be explained, because the temperature displayed on the thermometer is not the temperature of the patient at all, but the temperature of the corpse being baked."

"Yes." Gu Chen was very pleased to see that Lu Weiwei had been able to sort out the doubts of the whole case under his own guidance.

But at the same time, Gu Chen has also been able to identify several characteristics of the murderer.

The murderer must first be a drunk driver who likes to drink very much.

Moreover, after the car accident, Dr. Liu was found dead on the spot. In order to avoid responsibility, he secretly hid Dr. Liu's battery car.

Afterwards, Dr. Liu's body was baked with gasoline to speed up the decomposition of Dr. Liu's body.

From this point of view, the murderer must be a person with a certain level of knowledge. Coupled with the car accident, it is not particularly difficult to sort out the whole clue.

Thinking of this, Gu Chen hurriedly said again: "Senior Sister Lu, we should join Senior Brother Wang and Senior Brother He right now. It seems that the murderer should be found."

"Then what are you waiting for?" Lu Weiwei couldn't wait now, and immediately responded: "Get in the car, I'll drive this time."

Not long after, Lu Weiwei drove back to the scene of the crime just now.

Officer Wang and Officer He were already waiting by the side of the road.

Everyone was talking to each other about the situation, preparing to contact the vehicle and load Dr. Liu's battery car back.

Seeing Gu Chen and Lu Weiwei come back with clues, Officer Wang hurriedly asked them about the situation.

Gu Chen also briefly reported the black wallet and thermometer he found around the scene to Officer Wang and Officer He.

Neither of them expected that Gu Chen could find such key clues around the scene where the body was found.

Police officer He thought that he had wrongly blamed Gu Chen and Gao Chuanfeng before, so he reluctantly said: "Gu Chen, I was wrong before, and I shouldn't doubt you. I just feel that the situation you identified at the time and the situation I know There is a big difference, so I will only say a few words."

He looked at Police Officer Wang beside him, smiled and said, "Old Wang knows my temper. I always say what I say, and I have a straight temper."

"Sometimes the leaders of the Municipal Bureau come to inspect the work below. If they do something wrong, I will point it out straightforwardly."

"As for face and so on, it all depends on strength, and I recognize strength as a person."

It was also seeing Police Officer He have a heart-to-heart with him, Gu Chen just wanted to speak, but was interrupted by Lu Weiwei directly.

"Then Senior Brother He, what do you think of my Senior Brother Gu's strength?"

"This..." Officer He looked at Gu Chen beside him, and couldn't help laughing dryly: "Of course you have strength, but if you can help me catch the real culprit, then I, Old He, will really admire you, Gu Chen."

"It's easy to say." Gu Chen never liked being treated politely by others, and it was his job to catch the murderer.

But since Officer He said so, he agreed casually.

According to the current clues to search and arrest, in fact, the scope can be narrowed down a lot. Compared with no clues before, it can be said to be a big step forward.

"Senior Brother He, I need the assistance of your colleagues at the police station." Gu Chen said.

Officer He smiled: "Of course, tell me, how can we help you?"

"First." Gu Chen turned around and said lightly, "It is to investigate the vehicle involved. Although there is no surveillance at the first scene, Brother He also said that this road is not a main road, and it is relatively simple."

"Then we can calculate the time from the monitored intersections to the scene of the crime based on the calculation at [-]:[-] at that time."

"Circle the time frame, look for the vehicles that passed during this period, and find out all the vehicles that may cause accidents."

"This is no problem. There are still some sections of this road that are monitored. With the time when the incident happened, we can do it." Officer He said.

"Very good." Gu Chen nodded, and said again: "In addition, among the drivers of the vehicle that may have caused the accident, find a person with a higher education level, and this person must be particularly fond of drinking, and has a history of drunk driving. Pay special attention."

Police officer He took a small notebook to remember that he didn't know how to win, so he hurriedly said: "Gu Chen, please speak slowly, just find the kind of driver who likes to drink and has a previous drinking record, and he must have a higher level of education, right?"

"Yes, these characteristics are indispensable. If not, then find the closest one among these drivers." Gu Chen said.

Officer He nodded: "Understood, I'll ask someone to do this right away, what else?"

"Also, go to a nearby gas station to see who has frequently bought gasoline recently."

"Attention, it's the kind that obviously has oil in the car, but you have to buy it separately. Focus on investigating."

"The time went from the early morning two nights ago to before the body was found today."

"Okay." After completing the records with a small notebook, Police Officer He immediately said: "Okay, I will give you an order now, let the brothers check the information carefully according to the information you provided, and I will notify you immediately when I get the news."

"Yes." Gu Chen was not worried about Officer He's efficiency.

Because this person's character is also vigorous and resolute.

Except for a bit of a bad temper and a bit more straightforward speaking, everything else is fine.

Police officer He also took out his mobile phone and started to contact the on-duty colleagues at the police station, asking the other party to record the clues provided by Gu Chen one by one, and then let everyone start searching.

After hanging up the phone, Police Officer He smiled and said to Gu Chen: "Why don't we go to the restaurant next to our police station for lunch. The investigation will take some time. We will wait while we eat. What do you think?"

Lu Weiwei rubbed her growling stomach, smiled diligently and said, "Senior Brother He, your words are too timely."

"Haha, so it's settled?" Officer He said.

"It's settled." Officer Wang and Gu Chen said in unison.
