"Junior Brother Gu." Lu Weiwei looked at his feet and reminded him intentionally.
"I know." Gu Chen nodded, knowing that something had been dropped just now, so he squatted down and picked up the objects on the ground.
At this time, Lu Weiwei also hurriedly came to his side. The object in Gu Chen's hand was a thermometer, which made both of them curious.
Gu Chen looked through the items in his wallet while looking for other clues.
In the black wallet, apart from some cash and receipts, this thermometer aroused Gu Chen's curiosity.
"Is this thermometer...did Dr. Liu carry it with him?" Lu Weiwei asked.
Gu Chen nodded slightly: "Absolutely, but why wasn't the cash in the wallet taken away? Could it be that the murderer accidentally left it behind while transporting the body?"
"I guess that's the case," Lu Weiwei said, taking the thermometer from Gu Chen's hand and holding it in front of her for observation.
For a profession like a doctor, it is normal to carry a personal thermometer with you so that you can easily measure the patient's temperature.
However, it is rare to put a thermometer in a wallet. This shows that Dr. Liu has a habit of carrying a thermometer with him.
Lu Weiwei held the thermometer and was about to swing it, but at this moment, Gu Chen's eyes suddenly froze and he grabbed Lu Weiwei's right hand.
"What's wrong?" Lu Weiwei looked at Gu Chen curiously.
"have some problem."
"Ask...question?" Lu Weiwei looked at the thermometer in her hand and couldn't help but ask: "What's wrong with this thermometer?"
"It's the temperature." Gu Chen said.
Lu Weiwei was stunned for a moment, then she frowned slightly and started to observe the temperature on the thermometer according to Gu Chen's prompts.
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 that moment.
"There is something obviously wrong with this thermometer. Look, its temperature actually shows 43 degrees."
"Oh my god, really!" Lu Weiwei frowned and saw the current temperature of the thermometer. She couldn't help but asked: "Isn't the scale of this thermometer not going down? Why is it still at 43 degrees?
The way it looks.”
"Senior Sister Lu, you haven't studied physics, okay?" Gu Chen also saw Lu Weiwei raising a question and couldn't help teasing her.
Lu Weiwei blushed and said a little embarrassedly: "Maybe I have learned relevant knowledge before, but how many years have passed and I still don't remember it now."
Looking at Gu Chen, Lu Weiwei smiled again and said, "I'm not your junior brother Gu. I have such a good memory, won't the thermometer's scale not drop? It's still maintained at 43 degrees after such a long time."
"Because the main working substance of the thermometer is mercury." Gu Chen said.
"This... I also know this. When I was a child, I remember that my family bought one, and it was also taught in physics class. The main working substance of the thermometer is indeed mercury, but..."
"But when the thermometer leaves the human 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 moment after hearing this, and asked Gu Chen weakly: "Is... is that so? You won't go back?"
"Sister Lu." Gu Chen held the thermometer directly in front of her and said, "You may have forgotten that when the thermometer comes into contact with the human body, the mercury in the tube will expand and rise when heated."
"When the temperature of the mercury is balanced with the body temperature, the mercury will stop expanding and reach a stable temperature."
"Yes, that's the case." Lu Weiwei nodded silently and added: "Isn't it the same when measuring body temperature? The measured body temperature is often the highest value of the human body's temperature. I remember it was tucked 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, the thermometer is removed from the human body. The mercury shrinks when it is cold, and the narrow part of the thermometer
It will automatically disconnect."
"The mercury that has risen into the mercury column will not retreat, but will stay where it is. In this way, people can judge the temperature of the human body based on the height of the mercury."
"After using the thermometer, you must swing the thermometer downward vigorously to make the mercury in the mercury column slide down into the vacuole, so that it will not affect your continued use next time."
Under Gu Chen's words, Lu Weiwei acted as seriously as a primary school student listening and nodded frequently.
"I understand, Junior Brother Gu, what you mean is that if you don't shake the thermometer vigorously, the temperature in the thermometer will remain at the temperature of the last measurement, right?" Lu Weiwei asked.
Gu Chen nodded: "That's what I mean."
"But." Lu Weiwei looked at the exaggerated number of 43 degrees on the thermometer and couldn't help but said jokingly: "But Junior Brother Gu, have you ever thought about who can have a high fever of 43 degrees and still live well? Could it be the last time Dr. Liu saw a doctor?
The old lady?”
"If that's the case, wouldn't the old lady be dead? Can she still survive? This kind of high fever is terrible."
Of course Lu Weiwei knows that the normal temperature of the human body is usually around 37 degrees, and a fever of 40 degrees is already a very fatal thing.
A high fever of 43 degrees? Lu Weiwei has never seen such a person.
After Gu Chen thought quietly for a few seconds, he said, "How about asking Officer He to contact the patient's home to see what the situation was like 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 the phone and started to contact Officer Wang.
Gu Chen, on the other hand, continued to search around the scene.
Not long after, Lu Weiwei received a call back from Officer Wang. After communicating with each other, Lu Weiwei hung up the phone.
"Junior brother Gu, I have already inquired with the patient. The patient had a slight fever that night, about 39 degrees. Dr. Liu measured it."
"Moreover, I also roughly explained to them the situation on our side."
Listening to Lu Weiwei's words, Gu Chen felt even more curious and couldn't help but shake his head.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "No, I have a fever of 39 degrees, why does the thermometer show 43 degrees?"
"If we look at it normally, after taking the temperature, doctors usually shake it vigorously to keep the thermometer in its original position."
"But the temperature that Dr. Liu measured for the old lady was 39 degrees, and this was the last patient that Dr. Liu saw. After that, Dr. Liu disappeared."
"Yes, the old lady is indeed the last patient that 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 that... after Dr. Liu treated the old lady and took her temperature, he went to treat other patients?"
"No." Gu Chen directly refuted Lu Weiwei's remarks: "Think about it, based on the situation at the time, Dr. Liu did leave directly on a battery car after seeing the patient."
"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 occurred."
"From the blood stains and the battery car we found at the scene just now, we can conclude that this car accident was bound to happen."
"And I have extracted relevant blood stains from the scene. As expected, I took it to the technical department for identification. The blood stains should be Dr. Liu's."
"Yes." When Gu Chen said it, Lu Weiwei came back to her senses from her previous reasoning, and then said: "Indeed, if the blood stains on the road belong to Dr. Liu, it means that Dr. Liu came out of the patient's home.
I never treated anyone else again."
"So, if Dr. Liu measured the temperature without using a thermometer, the temperature on the thermometer should be 39 degrees, not the exaggerated 43 degrees."
Gu Chen nodded: "You are right, so this temperature is definitely abnormal. There should be other reasons."
Thinking of this, Gu Chen suddenly smelled a faint smell of gasoline.
There didn't seem to be much of a reaction at first, but now I feel more and more like the smell of gasoline is around me.
"What's wrong?" Seeing Gu Chen sniffing all the time, Lu Weiwei couldn't help but ask him.
Gu Chen did not answer, but looked at the black wallet in his hand.
He immediately took the wallet in front of him, and after looking around a few times, he found that there were obvious signs of scorching on one corner of the black wallet.
I put it to the tip of my nose and smelled it, and there was indeed a smell of gasoline.
"That's the smell." Gu Chen was overjoyed and couldn't help but snap his fingers and said, "I know, I know what's going on with the thermometer."
Seeing that Gu Chen was overly excited and felt like he had won the lottery, Lu Weiwei quickly 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. The reason is here."
Gu Chen walked back and forth in front of Lu Weiwei twice, holding the wallet in his left hand and the thermometer in his right hand. He felt that these two things were the key clues he found.
"It's not that you wait a minute." Lu Weiwei was confused by Gu Chen's comment. She quickly scratched her head and calmed down before asking again: "You mean, the body was roasted by fire, right?"
"Yes, that's it." Gu Chen brought the black wallet to Lu Weiwei: "Senior Sister Lu, look at this position of the black wallet, did you find anything?"
"Uh! It seems like it's been scorched, and the leather surface is a little burnt."
"Smell it again." Gu Chen moved the black wallet closer.
Lu Weiwei stretched her neck and sniffed: "Eh? Why does it smell like gasoline? Has it been baked by gasoline?"
Gu Chen smiled, first put the wallet into one evidence bag, and then put the thermometer in another evidence bag, and then asked: "You should understand what's going on now, right?"
"I know." Lu Weiwei smiled and said: "The murderer used gasoline to bake the body, so it accelerated the decomposition."
"This can also explain why Junior Brother Gu and Gao Chuanfeng both determined that the death time of the deceased was about a week, because you judged based on the normal decomposition rate of the corpse."
"Yes, that's why there was a conflict with the clues obtained by Officer He at that time." Gu Chen said.
Lu Weiwei smiled and shook her head: "Let me tell you, you two studied under Forensic Doctor Liu, how could you make such a big mistake?"
"Because the corpse was deliberately baked by the murderer, the murderer used a clever trick on the time of death in order to cause trouble to the police and prevent them from finding out Dr. Liu's time of death."
"The murderer took advantage of this and abandoned the baked body of Dr. Liu in the wilderness, separating it from the first scene of the crime."
"As a result, it will definitely be more difficult for our police to investigate who the murderer is."
"The temperature of the thermometer is as high as 43 degrees, which can be explained because the temperature displayed on the thermometer is not the temperature of the patient at all, but the temperature at which the body was baked."
"Yes." Gu Chen was very pleased to see that Lu Weiwei had been able to sort out the doubtful points of the entire case based on 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 drinking very much.
Moreover, after a car accident, Dr. Liu was found dead on the spot. In order to avoid responsibility, Dr. Liu's battery car was secretly hidden.
Dr. Liu's body was then 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 entire clues.
Thinking of this, Gu Chen quickly said: "Senior Sister Lu, we should immediately join up with Senior Brother Wang and Senior Brother He. It seems that the murderer can be found."
"Then what are you waiting for?" Lu Weiwei couldn't wait now, and immediately responded: "Get in the car, I will drive this time."
Not long after, Lu Weiwei drove back to the scene of the crime.
This chapter is not over yet, please click on the next page to continue reading the exciting content! Officer Wang and Officer He are already waiting on the roadside.
Everyone was chatting with each other about the situation, preparing to contact the vehicle and load Dr. Liu's battery car back.
Seeing Gu Chen and Lu Weiwei returning with clues, Officer Wang quickly asked them about the relevant situation.
Gu Chen also briefly reported to Officer Wang and Officer He about the black wallet and thermometer he found around the scene.
Neither of them expected that Gu Chen could find such key clues around the scene where the body was found.
Officer He thought that he had wrongly blamed Gu Chen and Gao Chuanfeng before, and then said with some reluctance: "Gu Chen, it was my fault before and I shouldn't have doubted you. I just felt that the situation you identified at that time was different from what I knew.
There is a big difference, so I can only say a few words."
He looked at Police Officer Wang next to him, and smiled and said, "Old Wang knows my temper. I always say what I say, and I have a straightforward temper."
"Sometimes the leaders of the municipal bureau come to inspect the work. If they do something wrong, I will point it out outright."
"As for face and so on, it all depends on strength. I am a person who believes in strength."
Seeing that Officer He was having a heart-to-heart with him, Gu Chen was about to speak, but was interrupted by Lu Weiwei's direct intervention.
"So, Senior Brother He, what do you think of my Junior Brother Gu's strength?"
"This..." Officer He looked at Gu Chen beside him, and couldn't help but laugh twice and said: "Of course you have the strength, but if you can help me catch the real murderer, then I, Mr. He, really admire you Gu Chen."
"Easy to say." Gu Chen never liked others to be polite to him. It was his own job to catch the murderer.
But since Officer He said this, he agreed casually.
According to the current clues, the scope of the search can actually be reduced a lot. Compared with the previous situation where there were no clues, it can be said to be a big step forward.
"Senior Brother He, I need the help of your colleagues at the police station." Gu Chen said.
Officer He smiled: "Of course, tell me how we can help you?"
"First." Gu Chen turned around and said calmly: "It is to investigate the vehicles involved. Although there is no surveillance at the first scene, Senior Brother He also said that this road is not a main road and is relatively simple."
"Then we can calculate it based on the time at 0:03 and calculate the time from the monitored intersections to the crime scene."
"Circle the time range, look for the vehicles that passed during this period, and find all the vehicles that may have caused the accident."
"This is no problem. There are still some sections of this road that are monitored. With the time of the incident, we can definitely do it." Officer He said.
"Very good." Gu Chen nodded and added: "In addition, among the drivers of these vehicles that may have caused the accident, find a person with a higher education level, and this person should especially like to drink and have a record of drunk driving.
Pay special attention."
Officer He was not very successful with his small notebook, so he quickly said: "Gu Chen, please slow down, you just want to find the kind of driver who likes to drink and has a history of drinking, and you also need to 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: "I understand, I'll have someone take care of this right away. What else is there?"
"Also, go to the nearby gas stations and ask if anyone has purchased gasoline frequently recently."
"Attention, it's the kind that clearly has oil in the car, but it's purchased separately. Let's focus on the investigation."
"The time ranged from early morning two nights ago to before the body was found today."
"Okay." After taking the small notebook and recording everything, Officer He immediately said, "Okay, I'll go ahead and ask the brothers to check it out based on the information you provided. I'll let you know as soon as I get the news."
"Okay." Gu Chen was not worried about Officer He's efficiency.
Because this person's character is also vigorous and resolute.
Except for having a bad temper and speaking outright, everything else is fine.
Officer He also took out his mobile phone and began to contact his colleagues on duty at the police station. He recorded the clues provided by Gu Chen one by one, and then asked everyone to start a search.
After hanging up the phone, Officer He smiled and said to Gu Chen: "How about this? We go to the restaurant next to our police station for lunch at noon. The investigation will take some time. Let's eat and wait. What do you think?"
Lu Weiwei touched her growling belly and said with a smile: "Senior Brother He, your words are so timely."
"Haha, then it's settled?" Officer He said.
"It's settled." Officer Wang and Gu Chen said in unison. If you like I Am a Super Police Officer, please bookmark it: (www.sodu777.net) I Am a Super Police Officer has the fastest update speed on the entire Internet.
