[Chapter 72, Speed ​​Train 5-The Cause of Li Zhemin's Death]

When Li Zhemin was found dead, the other three elderly people in the same room immediately started screaming.

The ear-piercing screams alarmed the other passengers in the same compartment, and the other eight senior citizens also ran over.

The old lady who had dinner with Li Zhemin yesterday nervously pushed his body: "Old Li, wake up, wake up!" There were two old ladies talking together: "What's going on?" What's wrong with Lao Li?" "Oh my God, if you can't wake up after so long, you must be dead!"

Hearing the word "dead", the elders all looked shocked and began to discuss in whispers, and some even took a step forward, wanting to lift the quilt of the deceased to see the situation.

Yu Hanjiang sternly said, "Everyone, please go out and don't mess with the corpse!"

The flight attendant's face was extremely serious, and the voice frightened everyone like a thunderbolt. Yu Hanjiang scanned the crowd sharply, and everyone immediately took a step back consciously with pale faces, exited Room 2, and made way for a passage.

Yu Hanjiang strode into Room No. 2, his eyes quickly swept across the scene of the crime.

The red hats of the tourist group and the coats of the four people hung on the hangers of the upper and lower berths. Beds 2B, 2C, and 2D were a little messy because the old man had just woken up, but Li Zhemin's bed 2A was extraordinarily neat.

Yu Hanjiang lifted the quilt, and Li Zhemin put on a set of plaid pajamas, and the clothes were neatly dressed. He obviously never fought with anyone, and there was no sign of struggle—he was killed or even died in his sleep At that moment Li Zhemin was still dreaming sweetly, with a smile on his mouth, his face was extraordinarily peaceful.

Most people over the age of 60 sleep very lightly and are easily woken up. There are also some people with insomnia who can't sleep in the middle of the night.

There are four elderly people in room 2. Once one of them happened to be awake at the time, the risk of the murderer being discovered would be very high—obviously, the murderer knew the work and rest habits of these elderly people very well, and made sure that everyone was asleep before moving. hand.

It can be inferred from common sense that it would be easier for the three people in the same room as Li Zhemin to commit crimes, because he can observe whether other people and Li Zhemin are asleep at any time to ensure that he will not be discovered.

However, the possibility of committing crimes by the elderly in rooms 1 and 3 cannot be completely ruled out. After all, these people have been colleagues for many years, they know each other very well, and they often travel together. Maybe they know who loves insomnia and who snores. .

The tour guide Qin Shiyue was washing up. After hearing the voices in the carriage, she hastily wiped her face with a towel, and ran back quickly with the toiletry bag.

Seeing a group of people around the door of Room 2, Qin Shiyue grabbed a familiar old lady and asked nervously, "Aunt Zhang, what's going on?" The old lady pointed at Room 2 tremblingly. Said: "Lao Li seems to be dead..."

Qin Shiyue's complexion changed, and she walked over quickly, only to find that the flight attendant in carriage No. 6 was checking the condition of the deceased.

When she came to the door, the other party just looked up.

Those cold and sharp eyes almost pierced people's hearts, Qin Shiyue was startled by his cold eyes, took a deep breath to adjust his emotions, and asked in a trembling voice: "Li, is Uncle Li really dead? What's the matter?"

People around 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 a heart attack all the time!"

An old man next to him echoed: "Yes, yes, Lao Li has suffered from high blood pressure and heart disease for many years. His bed was originally the upper berth. He was worried that he would sleep high and get sick in the middle of the night, so he deliberately changed to the lower berth with me."

Another old man said: "He takes medicine on time every day. He has undergone heart surgery before, and it is said that a stent was installed!"

The three people who mentioned heart disease were the old man who lived in the same room as Li Zhemin.

Yu Hanjiang ignored their random guesses, and said in a low voice, "Xiao Qin, please go to compartment 4 and ask the steward to come over."

Qin Shiyue nodded with a pale face, and quickly turned around to go to the No. 4 carriage.

When she came to carriage No. 4, she happened to meet Xiao Lou who was rushing this way. Qin Shiyue hurriedly said: "Hello, are you the flight attendant of No. 4 car? The flight attendant of No. 6 car asked you to come over!"

Xiao Lou nodded his head politely, and rushed to the No. 6 carriage with big strides.

There was so much movement in carriage 6 early in the morning, even though there was a whole section of dining cars in between, Xiao Lou could still hear screams, and many passengers in carriage 4 were also looking there curiously.

There must be something wrong with Team Yu's carriage, Xiao Lou immediately turned around and walked over there, just in time to meet the tour guide sent by Team Yu to call him.

Xiao Lou asked as he walked, "What happened?"

Qin Shiyue's face was as pale as a sheet of paper: "In our group, an old man passed away suddenly... My God, with such a big accident, I will definitely be fired by the travel agency after I go back!"

Seeing the troubled look on the girl's face, Xiao Lou comforted her in a low voice: "Don't worry, if it's murder, you're not responsible, and the travel agency might reconsider it. I hope you can cooperate with our investigation."

Qin Shiyue's eyes widened in disbelief: "Murder, murder? Didn't Uncle Li have a heart attack?"

Seeing the girl's bewildered expression, Xiao Lou couldn't help but feel sympathy in his heart. The freshly graduated college student traveled with a group of seniors carefully and conscientiously. As a result, someone in the group died suddenly. This was not an ordinary blow to her, and she might go back. will suffer

Punishment, loss of work.

Xiao Louwen said: "We can't come to a conclusion yet, we can confirm after we check. Xiao Qin, please sort out the information of the entire tour group, including the form they filled out when they signed up for the travel agency, and we will get it from you later."

Qin Shiyue nodded with a complicated expression: "Okay, okay..."

Xiao Lou quickly came to the No. 6 compartment through the dining car, and he found a group of old people surrounded the No. 2 room with panicked expressions.

The family of four in room 4 poked their heads out when they heard the movement. The 3-year-old child who accidentally inhaled raisins yesterday asked in a childlike voice: "Mom, what's the matter? Why are the grandparents gathered around there? There is something interesting." Well, I want to see it too!"

When the woman heard the discussion around her, she seemed to be dead. Her face 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 kids.

In Room 5, a passenger got off the bus yesterday, and Mo Jiaran switched to sleep.

The noisy sound outside woke her up, and the eldest lady was quite angry when she got up, she opened the door with a dark face, and said loudly: "It's so early in the morning that people are not allowed to sleep, why are you making so much noise! ​​Can you please keep your voice down?! "

An old lady next to her said, "Girl, someone died in room 2..."

Mo Jiaran's face turned pale suddenly, and she immediately turned over and got out of bed, screaming like a frightened cat and ran towards the No. 4 carriage. Xiao Lou stopped her and said calmly, "Everyone is not allowed to leave."

Mo Jiaran shivered and pointed to Room 2: "My God, there's a dead person over there! I don't want to stay in Car 6 anymore..."

Xiao Lou opened the door of car No. 4, smiled and said, "Go in."

Mo Jiaran's face was pale and he refused to cooperate.

Xiao Louwen said: "Don't be afraid, it will be safer to stay in the room."

Hearing Xiao Lou's words, everyone's expressions turned ugly, and Mo Jiaran reluctantly returned to Room 4.

Xiao Lou turned around and locked the door at the junction of the carriages.

Hearing his voice, Yu Hanjiang came out of Room 2 tacitly, and said in a low voice: "Car 6 is temporarily closed, everyone please go back to your room, we need to investigate every passenger, thank you for your cooperation."

An old lady next to him said, "What are you investigating? Lao Li suddenly disappeared. He obviously died of a heart attack, right?"

Someone complained: "What can you find out, don't you still do autopsies?!"

Xiao Lou smiled slightly, looked at him and said, "That's right, we will do an autopsy."

The old man froze for a moment, his face was terrified.

Xiao Lou said warmly: "Don't panic, uncles and aunts, please go back to your room first. The three of you in Room 2, please wait in the corridor for a while."

He and Yu Hanjiang looked at each other, nodded to each other, and then walked into room 2 together, closing the door behind them to block the view from the outside.

If there are no medical-related professionals among the challengers and they cannot determine the cause of Li Zhemin's death, what they should do at this time is to go to the No. 4 car and invite the doctor "NPC" Jing Weiguang over.

But Xiao Lou and Yu Hanjiang didn't need Dr. Jing's help—Xiao Lou's on-site autopsy was more professional than Dr. Jing's.

Yu Hanjiang took a step back consciously to give Xiao Lou enough space.

Xiao Lou put on a pair of gloves, leaned over to lift off the clothes of the deceased, and checked the corpse deftly.

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 trousers, and indeed he saw surgical marks on the thighs. While examining, he explained: "Stent implantation surgery is generally used for coronary artery stenosis in the heart."

He pointed to the mark on the thigh and said, "Look here, Captain Yu. There is a surgical scar on the femoral artery of the deceased's right leg. The doctor opened the vascular channel through the femoral artery and pushed the stent from here to the heart vessel. This operation is very difficult. It is common and has a high success rate. When the implanted stent stretches the narrowed blood vessel, the blood flow of the patient's heart will return to normal."

Xiao Lou checked the deceased's face, pupils, muscles, and the skin condition of the whole body, and then concluded: "He did not die suddenly from a heart attack. The plaques on the corpse of a patient who died suddenly from a heart attack will be very obvious, usually dark purple in color. Red, due to the congestion of a large number of organs and tissues in the body, the body stiffened too quickly, and there were obvious scattered bleeding spots on the body. Li Zhemin's situation does not match. "

He carefully observed the deceased's nails, oral mucosa and other details, and said: "The possibility of poisoning is not high."

It wasn't a heart attack, nor was it poisoned, and there were no signs of being stabbed or hit on his body. Li Zhemin's death was simply unknown and unnoticed. 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 around the navel and upper arm of the deceased, and said, "Captain Yu, there are many needle holes on his body."

Yu Hanjiang was slightly taken aback: "Could it be that he takes drugs?"

Xiao Lou shook his head: "It may be left by the injection of drugs." He opened the door and asked the three old men standing at the door: "Uncles, besides heart disease, does Li Zhemin have any other medical history? For example... Diabetes ?”

The three looked at each other, and one of them suddenly said: "It seems that there are three highs, high blood pressure, high blood fat, and high blood sugar. Lao Li mentioned before that he got the three highs, and he wants to eat vegetarian or something."

Xiao Lou looked at Yu Hanjiang: "Search Li Zhemin's luggage."

Yu Hanjiang nodded, and took Li Zhemin's bag from the luggage rack - there were several magazines in the bag, and some

medicine.

This old Li is like a medicine jar, there are 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.

Xiao Lou introduced to Team Yu while looking at it: "This bottle is antihypertensive medicine. These two bottles are for softening and relaxing blood vessels. They are gastric mucosal protective agents; nitroglycerin is a commonly used emergency medicine for coronary heart disease; this bottle is for treating acute Diarrhea, this bottle is for a cold and fever..."

As Xiao Lou explained the functions of the medicine bottle by bottle, the old people around were dumbfounded.

An old man was shocked and said: "Are all the current flight attendants so good, do they know all the medicine?"

Xiao Lou didn't explain, looked at Yu Hanjiang, and whispered in his ear, "No insulin."

Yu Hanjiang understood, and closed the door smoothly, keeping the curious old people out.

Xiao Lou lowered his voice and said, "Diabetic patients 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 blood vessel dilating medicines, which he must take every day; other medicines for diarrhea, headache and cold. Yes, I should take a spare when I go out. However, the most important insulin is not in the bag, which is absolutely unreasonable.”

Yu Hanjiang didn't know enough about medical knowledge, so he couldn't help asking: "Could it be stolen by the murderer? Can insulin kill people?"

Xiao Lou nodded: "Originally, insulin is a life-saving medicine, which solves the problems of many diabetic patients. It can lower blood sugar. But once the insulin is injected too much, the body's glucose metabolism has problems, and the blood sugar is completely consumed and dropped to an extremely low level. value, the brain tissue will be irreversibly damaged, leading to coma, syncope, and unconscious death in sleep."

Yu Hanjiang's pupils suddenly shrank.

From this point of view, Li Zhemin's death was obviously related to insulin overdose.

Fortunately, Xiao Lou was professional enough to quickly determine the cause of death—several pinholes around the navel 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, and he agreed with the reasoning that he was injected with a large amount of insulin in his sleep, and his blood sugar dropped to the limit, which led to fainting.

Yu Hanjiang couldn't help but think to himself, bringing a forensic doctor through the barrier would be very efficient, and the cause of death could be deduced in less than half an hour.

He looked at Xiao Lou appreciatively, and said: "Since 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 not to be noticed by others, the best way for the murderer is to Dispose of the insulin vials and syringes."

The dose of insulin he carried was limited, and he had to inject it all in one go to kill Li Zhemin. If his insulin bottle was suddenly empty, it would definitely be suspicious if he searched his luggage. Team Yu's speculation was reasonable, the murderer must have disposed of the tools of the crime.

Xiao Loudao: "Let's search the trash can?"

Yu Hanjiang nodded.

The two walked out together, went to the end of the carriage to open the trash can, endured the strange smell of food and searched quickly.

The contents of the entire garbage bag were searched, but no trace of medicine bottles or syringes was found.

Xiao Lou asked in a low voice: "Could it be that the murderer threw these things into another compartment? But if this is the case, if you happen to bump into someone who goes to the toilet in another compartment in the middle of the night, you will leave a clue instead."

Yu Hanjiang frowned, and said, "The murderer is so cautious, he probably wouldn't rush to throw garbage in other cars that he is not familiar with."

Suddenly, he found a lunch box next to it. The box was tightly covered. On the surface, people who throw garbage are more hygienic. The lunch box is tightly covered to prevent the unfinished soup 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 emptied insulin vials.

The two looked at each other—through the autopsy and medical history, their reasoning about the murder method was completely correct.

Now it's time to find the murderer!
