[Chapter 72, Speed Train 5-The Cause of Death of Li Zhemin]
Upon discovering that Li Zhemin was dead, the other three elderly people in the same room immediately started screaming.
The piercing screams alerted other passengers in the same carriage, and eight other senior citizens also ran over.
The old lady who had dinner with Li Zhemin yesterday pushed his body nervously: "Old Li, wake up, wake up quickly!" There were two old ladies next to him talking together: "What's going on?"
What's wrong with Lao Li?" "Oh my God, he couldn't wake up for so long, he must be dead!"
Hearing the word "dead", the elderly looked shocked and started talking among themselves. Some even stepped forward to lift the quilt of the deceased to see what was going on.
Yu Hanjiang said sternly: "Please get out, everyone, and don't touch the bodies!"
The flight attendant's face was extremely serious, and the voice was like thunder, which frightened everyone at the same time. Yu Hanjiang swept the crowd with sharp eyes, and everyone immediately stepped back consciously with pale faces, exited Room 2, and made way for a passage.
Yu Hanjiang strode into Room 2 and quickly scanned the crime scene.
The red hats of the tour group and the coats of the four people were hung on the hangers on the upper and lower bunks. The three beds 2b, 2c, and 2d were a little messy because the old man had just gotten up, but Li Zhemin's bed 2a was particularly neat.
Yu Hanjiang lifted the quilt, and Li Zhemin changed into a set of pajamas, and his clothes were neatly dressed. He obviously did not fight with anyone, and there was no sign of any struggle - he was killed in his sleep, and even at the moment of death, Li Zhemin
He was still dreaming sweetly, with a smile on his lips and a particularly peaceful face.
Most elderly people over 60 years old sleep very lightly and are easily woken up. There are also some people with insomnia who cannot fall asleep in the middle of the night.
There are four elderly people in Room 2. Once one of them happens to be awake at the time, the risk of the murderer being discovered will be very high - obviously, the murderer knows the daily habits of these elderly people very well and will only move after making sure that everyone is asleep.
hand.
It can be inferred from common sense that it will be easier for three people in the same room with Li Zhemin to commit crimes, because he can always observe whether other people and Li Zhemin are asleep to ensure that he will not be discovered.
However, we cannot completely rule out the possibility that the elderly people in Rooms 1 and 3 committed the crime. After all, these people have been colleagues for many years, know each other very well, and often travel together. It may be clear who loves insomnia and who snores.
.
Tour guide Qin Shiyue was washing up at the time. After hearing the shouts in the carriage, she hurriedly wiped her face with a towel and ran back quickly with a toiletry bag.
Seeing a group of people surrounding the door of Room 2, Qin Shiyue immediately grabbed a familiar old lady and asked: "Aunt Zhang, what's going on?" The old lady pointed to Room 2 and said, trembling:
"Old Li seems to be dead..."
Qin Shiyue's expression changed, and she walked over quickly and found that the conductor in Car No. 6 was checking the condition of the deceased.
When she came to the door, the other person just raised his head.
The eyes were cold and sharp, almost piercing people's hearts. Qin Shiyue was startled by his cold eyes, took a deep breath to adjust her mood, and asked in a trembling voice: "Li, is Uncle Li really dead?
What the hell is going on?”
People around them shook their heads: "I don't know."
The bald old man suddenly said: "Could it be a heart attack? I remember that Lao Li seems to have always had a heart attack!"
An old man next to him echoed: "Yes, yes, Lao Li has had high blood pressure and heart disease for many years. His bed was originally an upper bunk. He was worried that he would get sick in the middle of the night if he slept high, so he specially changed to the lower bunk with me."
Another old man said: "He takes medicine on time every day. He had a heart operation before, and it is said that he even had a stent installed!"
The three people who mentioned heart disease were the old men who lived in the same room as Li Zhemin.
Yu Hanjiang ignored their random speculations and whispered: "Xiao Qin, please go to Car No. 4 and ask the flight attendant to come over."
Qin Shiyue nodded with a white face and quickly turned around to go to carriage No. 4.
When she came to Car No. 4, she happened to meet Xiao Lou who was rushing here. Qin Shiyue said hurriedly: "Hello, are you the conductor of Car No. 4? The conductor of Car No. 6 asked you to come over!"
Xiao Lou nodded politely and strode to Car No. 6.
The noise in Car No. 6 was so loud early in the morning. Although there was a whole dining car in between, Xiao Lou still heard the screams. Many passengers in Car No. 4 were also looking over there curiously.
There must be something wrong with Captain Yu's carriage. Xiao Lou immediately turned around and walked that way, and happened to meet the tour guide sent by Captain Yu to call him.
Xiao Lou asked as he walked: "What happened?"
Qin Shiyue's face was as pale as paper: "An old man in our group suddenly passed away... Oh my God, if such a big accident happens, I will definitely be fired by the travel agency after I go back!"
Xiao Lou saw the girl's troubled face and comforted her in a low voice: "Don't worry, if it is murder, you are not responsible. The travel agency may reconsider. I hope you can cooperate with our investigation."
Qin Shiyue's eyes widened in disbelief: "Conspiracy, murder? Didn't Uncle Li have a heart attack?"
Seeing the confused look on this girl's face, Xiao Lou couldn't help but sympathize with her. The newly graduated college student took a group of senior citizens on a trip. They were cautious and conscientious along the way. As a result, someone in the group suddenly died. It was not an ordinary blow to her. Maybe she would be gone when she returned.
You will be punished and lose your job.
Xiao Lou said warmly: "We can't draw a conclusion now. We can only confirm it after we check it. Xiao Qin, please sort out the information of the entire tour group first, including the forms they filled out when they signed up for the travel agency. We will get it from you later."
Qin Shiyue nodded with a pale face: "Okay, okay..."
Xiao Lou quickly passed through the dining car and arrived at Car No. 6. He found a group of elderly people surrounding Room 2 in a panic.
A family of four in Room 4 poked their heads out when they heard the commotion. The 3-year-old child who accidentally sucked in raisins yesterday asked in a sweet voice: "Mom, what's wrong? Why are the grandparents gathered around there? It's fun to have fun."
Well, I want to go and see it too!”
The woman heard the commotion around her, as if someone had died. Her expression changed and she immediately took the child back: "It's okay, baby, let's not go out. Can we watch cartoons in the room?" She closed the door.
, obviously not wanting to scare the children.
In Room 5, a passenger got off the bus yesterday, and Mo Jiaran came over to take a nap.
The noisy sound outside woke her up. The eldest lady was very angry when she got up. She opened the door with a dark face and said loudly: "It's so early in the morning that we don't let anyone sleep. What's the noise? Can you please keep it down?!"
"
An old lady next to me said: "Girl, there is a death in room 2..."
Mo Jiaran's face turned pale suddenly, and she immediately got out of bed, screaming like a frightened cat and ran to Car No. 4. Xiao Lou stopped her and said calmly: "No one is allowed to leave."
Mo Jiaran trembled and pointed to Room 2: "Oh my god, there are dead people over there! I don't want to stay in Car Room 6 anymore..."
Xiao Lou opened the door of car No. 4, smiled and said, "Get in."
Mo Jiaran's face turned pale, and Xiao Lou said warmly: "Don't be afraid, it will be safer if you go to the room."
Hearing Xiao Lou's words, everyone's faces looked a little ugly.
Xiao Lou turned around and locked the door at the junction of the carriages.
Yu Hanjiang heard his voice and immediately came out of Room 2 in tacit agreement and whispered: "Car No. 6 is temporarily closed. Please everyone return to their rooms. We need to investigate every passenger. Thank you for your cooperation."
An old lady next to her said, "What are you investigating? Lao Li suddenly disappeared. Did the star die suddenly of a heart attack?"
Someone complained: "What can you find out? Do you even conduct an autopsy?!"
Xiao Lou smiled slightly, looked at him and said, "Yes, we will indeed conduct autopsies."
The old man was stunned for a moment, looking very embarrassed.
Xiao Lou said warmly: "Uncles and aunties, don't panic. Please go back to your rooms first. The three of you in Room 2, please wait in the corridor for a moment."
He and Yu Hanjiang looked at each other, nodded to each other, and then walked into Room 2 together, closing the door to block the outside view.
If there are no medical professionals among the challengers and they cannot determine the cause of Li Zhemin's death, what they should do at this time is go to Car No. 4 and invite the doctor "NPC" Jing Weiguang.
But Xiao Lou and Yu Hanjiang didn't need Dr. Jing's help - Xiao Lou performed an on-site autopsy and was more professional than Dr. Jing.
Yu Hanjiang consciously took a step back to give Xiao Lou enough space.
Xiao Lou put on a pair of gloves, leaned over to lift off the deceased's clothes, and inspected the body with quick hands and feet.
Yu Hanjiang reminded: "The people in the tour group just said that Li Zhemin has a bad heart and has undergone heart stent surgery."
Xiao Lou immediately took off the deceased's clothes, and sure enough he saw traces of surgery on the thigh. While checking, he said: "Stent placement surgery is generally used for coronary artery stenosis in the heart."
He pointed to the mark on his thigh and said: "Captain Yu, look here. There is a surgical scar on the femoral artery on his right leg. The doctor opened the vascular channel through the femoral artery and pushed the stent from here all the way into the heart vessel - this kind of surgery is very difficult.
It’s common and has a high success rate. When the stent is inserted to open the narrowed blood vessel, the patient’s heart blood flow will return to normal.”
Xiao Lou examined the deceased's face, pupils, muscles and skin condition all over his body, and then concluded: "He did not die suddenly of a heart attack. Patients who die suddenly of a heart attack will have prominent body spots, usually dark purple in color."
Red, due to congestion of a large number of organs and tissues in the body, the rigor mortis is too fast, and there are obvious scattered bleeding spots on the body. Li Zhemin’s situation is not consistent.”
He carefully observed the deceased's nails, oral mucosa and other details, and said: "The possibility of poisoning is not high."
It was not a heart attack or poisoning. There were no signs of stabbing or impact on his body. Li Zhemin's death was simply unknown to God and ghosts. It looked very much like the natural death of an elderly person in his sleep.
Yu Hanjiang frowned slightly: "Can you guess the cause of death?"
Xiao Lou was silent for a moment, carefully observed the area around the deceased's navel and upper arms, and said, "Captain Yu, there are many pinholes on his body."
Yu Hanjiang was slightly startled: "Is he taking drugs?"
Xiao Lou shook his head: "It may be caused by injected drugs." He opened the door and asked the three old men standing at the door: "Uncles, apart from heart disease, does Li Zhemin have any other medical history? For example...diabetes
?”
The three of them looked at each other, and one of them suddenly said: "It seems so! The three highs are high blood pressure, high blood fat, and high blood sugar. Lao Li mentioned before that he had the three highs and needed to eat a vegetarian diet or something."
Xiao Lou looked at Yu Hanjiang: "Search Li Zhemin's luggage."
Yu Hanjiang nodded and took down Li Zhemin's bag from the luggage rack - it contained several magazines and some medicine.
This Lao Li was simply a medicine jar, and there were more than a dozen bottles of medicine in the bag. Yu Hanjiang didn't know what these medicines were for, so he poured them all on the bed and showed them to Xiao Lou.
While watching, Xiao Lou introduced to Captain Yu: "This bottle is antihypertensive medicine. These two bottles soften blood vessels and dilate blood vessels. They are gastric mucosal protectors; nitroglycerin is a commonly used emergency medicine for coronary heart disease; this bottle is for acute treatment."
Diarrhea, this bottle is for cold and fever..."
As Xiao Lou explained the functions of the medicine bottle by bottle, the elderly people around him were stunned.
An old man asked in shock: "Are all flight attendants today so powerful? Do they know all the medicine?"
Xiao Lou did not explain. He looked at Yu Hanjiang and whispered in his ear: "There is no insulin."
Yu Hanjiang understood and closed the door smoothly.
Xiao Lou lowered his voice and said: "Patients with diabetes must carry insulin with them when traveling for a long time and use insulin on time every day to control blood sugar."
He looked back at the pile of medicines lying on the bed and said, "In Li Zhemin's bag, there are a bunch of messy medicines, such as antihypertensive medicines and medicines to relax blood vessels, which he must take every day; others are used to treat diarrhea, headaches and colds.
Yes, I should have a spare when traveling. However, the most important insulin is not in the bag, which is absolutely unreasonable."
Yu Hanjiang didn't know enough about medical knowledge. Hearing this, he couldn't help but ask: "Did it be stolen by the murderer? Can insulin kill people?"
Xiao Lou nodded: "Originally, insulin is a life-saving medicine that solves the problems of many diabetic patients. It can lower blood sugar. But once insulin is injected too much, there is a problem with the sugar metabolism in the body, and the blood sugar is consumed and drops to an extremely low level.
If the value exceeds the value, the brain tissue will be irreversibly damaged, leading to coma, syncope, and unconscious death in sleep."
Yu Hanjiang's pupils shrank suddenly.
From this point of view, Li Zhemin's death was obviously related to an overdose of insulin injection.
Fortunately, Xiao Lou was professional enough and quickly determined the cause of death - several pinholes around his belly button and upper arm, indicating that Li Zhemin had been injecting insulin for a long time to control blood sugar. However, the insulin in his backpack was missing; Li Zhemin died peacefully,
There was no struggle before death, which agrees with the theory that a large amount of insulin was injected during his sleep, and the blood sugar dropped to the limit, causing syncope.
Yu Hanjiang couldn't help but think to himself that it would be very efficient to bring a forensic doctor through, and the cause of death could be deduced in less than half an hour.
He looked at Xiao Lou and said: "If my guess is correct, the murderer injected a large amount of insulin into Li Zhemin. It is very likely that the insulin Li Zhemin carried has been used up. In order to avoid being noticed that something is wrong, the murderer's best course of action
, that is, get rid of all the insulin bottles and syringes."
The amount of insulin he carries with him when he goes out is limited, and he has to inject it all in one go to kill Li Zhemin. If his insulin bottle suddenly becomes empty, searching his luggage and finding it will definitely arouse suspicion - Captain Yu's speculation is very reasonable, and the murderer must have disposed of the crime tools.
Dropped.
Xiao Lou said: "Shall we search the trash can?"
Yu Hanjiang nodded.
The two of them walked out of the door together, went to the end of the carriage to open the trash can, and endured the strange smell of the food to quickly search it.
The contents of the entire garbage bag were searched, and no trace of medicine bottles or syringes was found.
Xiao Lou asked in a low voice: "Did the murderer throw these things into other carriages? But in this case, if he happened to bump into someone going to the toilet in other carriages in the middle of the night, it would leave clues."
Yu Hanjiang frowned and said: "The murderer is so cautious, he shouldn't rashly throw garbage in other unfamiliar carriages."
Suddenly, he found a lunch box next to him. The lid of the box was very tight. It seemed that the people who threw garbage were more hygienic. They covered the lunch box tightly to prevent the uneaten soup inside from flowing out.
But as Yu Hanjiang opened the box, Xiao Lou was surprised to find——
Inside the lunch box was a syringe and several empty insulin vials.
The two looked at each other - through autopsy and medical history, their reasoning about the murder method was completely correct.
Next it’s time to find the murderer!
