[Chapter 73, Speed ​​Train 6 - Suspect]

The two sorted out the evidence and put it back in the steward's office in front of the train. Xiao Lou looked at the syringes and empty bottles on the table, and asked thoughtfully: "Captain Yu, can we directly search the backpacks of the passengers? There will be some clues."

Yu Hanjiang thought about it carefully and said: "I remember the secret room of Heart 3. When the students went to the playground, we went to the classroom to search the schoolbags to find evidence. This secret room should also work. The identity of the flight attendant is just convenient for us to search at any time." He simply said: "Try it and you will know."

Xiao Lou nodded, turned around and followed Yu Hanjiang.

When the two came to Room 1, Yu Hanjiang said calmly: "At the request of the security department, we need to conduct a simple security check on your luggage. Please cooperate."

The passengers did not object as expected, and seemed to be accustomed to the flight attendant's security check.

An old man came over and asked Xiao Lou, "Did Lao Li have a heart attack?"

Xiao Lou smiled and said: "There is no definite conclusion yet, uncle, please give me the backpack."

The old man handed him the bag cooperatively, and said, "I didn't bring any flammable or explosive items. The bag is full of food."

Xiao Lou opened it and took a look—it really was a big bag of food, this old man is a foodie.

He casually asked: "How long will you stay in Moon City this time?"

The old man said: "Three days, and then go back by plane. Everyone doesn't have much luggage."

Xiao Lou turned his head and saw that everyone's luggage was a black backpack purchased uniformly by the travel agency. There was a luggage tag on the backpack with everyone's name written on it to avoid confusion.

Yu Hanjiang checked the luggage for the reason of "safety inspection", and the other three cooperated to take down the backpack.

Only the old lady on bed 1A is still reading the newspaper with her head down. This old lady is over seventy years old, with white hair, hunched back, wrinkled face, walking with a cane, and ear problems. Everyone else is taking good care of her. She, call her "Sister Mei".

Seeing that she didn't respond, an old lady next to her gently shook her arm: "Sister Mei, the flight attendant wants to check for safety."

Sister Mei was stunned for a moment, raised her head and asked, "What?"

The old lady yelled loudly in her ear: "The steward wants to check the luggage!"

Sister Mei still looked blank: "What?"

Yu Hanjiang pointed to her backpack and asked her to take it off. She finally understood the gesture and stood up tremblingly to get the bag. The old man next to her saw that she was inconvenient and helped her.

Yu Hanjiang opened her backpack and took a look. There were a few changes of old clothes, some antihypertensive medicine, a few newspapers, and nothing else.

The old man explained: "Sister Mei is old, her legs and feet are not very sharp, and her ears are not very good. She is the oldest senior in our unit. She has been in the company's personnel department since the boss started her business. Most of us were recruited by her. From the company, her daughter asked her to come out with us to relax, but she is still not happy, because she finds it troublesome to go out."

Xiao Lou and Yu Hanjiang looked at each other. Since this sister Mei is the oldest employee in the company, she must know something.

Her luggage was fine, and Yu Hanjiang planned to ask her alone later. I can't hear, but I can write. The old man wears a pair of thick reading glasses, so he should be able to read clearly, right?

These two backpacks were fine, and Xiao Lou and Yu Hanjiang quickly checked the remaining two separately.

Yu Hanjiang found some needles, cotton swabs, and a row of things like ballpoint pens in one of the backpacks. He didn't recognize it, so he showed it to Xiao Lou. After Xiao Lou looked it over carefully, he whispered in Yu Hanjiang's ear, "This is an insulin pen."

Yu Hanjiang looked through the name on the luggage tag of his backpack - Niu Dapeng.

He looked at the old man on bed C in Room 1 and asked, "Uncle Niu, is this bag yours?"

Niu Dapeng nodded: "Yes."

Xiao Lou smiled and asked, "Uncle, do you have diabetes too?"

Niu Dapeng said: "I have had this problem for many years, and I have been controlling it with insulin."

Yu Hanjiang then asked: "Then do you know that Li Zhemin has diabetes?"

Niu Dapeng looked calm: "I know, Lao Li and I have stayed in the same hospital before."

Yu Hanjiang wrote down this old man named Niu Dapeng.

The last package found no exceptions. The two left Room 1 and continued to search Room 2.

Since the deceased lived in No. 2, this room needs to be checked intensively.

The old man who changed places with the deceased and slept on the upper bunk happened to be the most obvious bald man in this group, with only half of his head being gray hair, which was highly recognizable. The man's name was Zheng Weiguo, and Yu Hanjiang found the same needles, cotton swabs and insulin pens in his bag.

Yu Hanjiang asked: "How long have you had diabetes?"

Zheng Weiguo looked embarrassed: "I didn't pay attention when I was young. I often ate big fish and meat. Five years ago, I was diagnosed with diabetes and high blood pressure. I have been using insulin and antihypertensive drugs to control it."

In addition, Yu Hanjiang found a pack of playing cards in an old man named Liu Yuming's bag. The other party explained: "Old Li likes to play poker. The four of us played upgrades last night. We didn't sleep until two o'clock in the morning."

Yu Hanjiang asked: "The lights are off, how do you play cards?"

Liu Yuming said: "I always love to go to the bathroom in the middle of the night, my eyes are bad, and I can't see clearly at night. This time when I go out, my son prepared a rechargeable lamp for me, so that I can take the lamp when I want to go to the bathroom. last night old

Li wanted to play cards, so I turned on the charging light and put it on the upper bunk for lighting. "

The other two nodded one after another: "That's right!" "Lao Li was quite happy when he played cards last night. I didn't expect... Sigh."

This group of old people actually played cards with the charging lights on until 2 o'clock in the morning, which is hard enough.

Yu Hanjiang asked him: "Did you go to the toilet in the middle of the night last night? Did you see anything?"

Liu Yuming shook his head: "I got up once at three o'clock, everyone was sleeping, and all the doors were closed."

Yu Hanjiang said: "Did Li Zhemin make any movement at that time?"

Liu Yuming thought about it carefully and said, "I remember that Lao Li seemed to have turned over and was still snoring lightly."

In other words, Li Zhemin's death time was after 3 am.

There was no other suspicious evidence in this room. When the two came to Room 3 and were about to check their luggage, an old lady suddenly said angrily, "What right do you have to search my luggage? This is an invasion of privacy!"

She looked extremely emotional.

This old lady is called Shu Ping. She is 60 years old this year, but she looks only 40 years old. Her skin and body are well maintained. Amy's old lady was wearing a skirt and her shoulder-length hair was curled. She was the youngest and most beautiful old lady in the group.

Yu Hanjiang said calmly: "Routine security check, please cooperate with Auntie."

Xiao Lou smiled and echoed Yu Hanjiang: "That's right, everyone else is very cooperative in the inspection. If you are worried about something private, you can follow us to the office alone, Auntie, and we will check it for you in private."

Shu Ping's face turned pale, she held her bag and refused to let go.

Her weird performance made the other three elderly people in the same room look sideways. Yu Hanjiang frowned and said, "If you don't cooperate, then I can only temporarily restrain you and wait for the guards to deal with it."

He stretched out his hand to ask for the other party's backpack. Shu Ping struggled for a long time before handing the backpack to Yu Hanjiang.

Yu Hanjiang opened it, and besides a change of clothes, insulin was found in the dark compartment at the bottom of the backpack again... However, this dose is too much, right? Almost twice as much as Niu Dapeng and Zheng Weiguo's backpacks.

Seeing that they found these, the old lady's face suddenly became extremely ugly.

Xiao Lou smiled and asked, "Auntie, how many years have you had diabetes? Why do you bring so much medicine?"

Shu Ping snatched the backpack, and said with a serious face: "It was found out last year that my condition was quite serious and I used a lot of medicine, so I brought more medicine than the average person."

The old lady next to her looked at her in surprise: "Xiaoping, you have diabetes too? Why didn't you tell us?"

Another person said: "Yes, diabetes is not a shameful disease. Many elderly people will suffer from it. Why are you hiding it from everyone?"

Shu Ping's face turned blue and white, and he hesitated for a long time but couldn't answer.

Xiao Lou and Yu Hanjiang exchanged glances, turned and left the room.

Other passengers also cooperated with the inspection, but most of them had nothing to do with the senior group, and their luggage was full of food and clothes.

After checking the entire No. 6 compartment, the two returned to the steward's office at the front of the compartment.

The space above the bullet train is limited, and the flight attendant's office is only about 1.5 square meters. There is a small table and a chair. Two big men standing inside are a little crowded, and their bodies are almost close to each other.

Yu Hanjiang is not used to being so close to people. If he talks too close, his breath will be on the other person's face, which is very impolite.

He offered to propose: "Professor Xiao, sit down."

Xiao Lou was also polite, and sat down on the chair, so that Yu Hanjiang's space would be relatively spacious. Xiao Lou raised his head, looked at Yu Hanjiang who was standing beside him and asked, "What do you think of Team Yu?"

Yu Hanjiang leaned back against the table, crossed his long legs casually, folded his arms around his chest, and said in a low voice: "At present, there are four clear suspects——Niu Dapeng in Room 1, who had lived in the hospital with the deceased before, and the two He was a patient in the same hospital, and he must have been well aware of the deceased's diabetes."

"Zheng Weiguo in Room 2 slept with the deceased on the upper and lower bunks. He played cards together until two o'clock in the morning. He could easily know whether the other people in the room were asleep, so he could commit crimes when Li Zhemin was sound asleep. Moreover, he is also a diabetic. .”

"Liu Yuming in room 2 said that he often went to the bathroom in the middle of the night, but it is also possible that this was just a cover-up. He got up at 3:00 in the morning and killed Li Zhemin, pretended to go to the bathroom, and threw away the syringe and insulin bottle, so that no one doubt him."

"There is also Shu Ping in room 3. When searching for luggage, this old lady was a little emotionally agitated. The insulin was hidden in the bottom of the backpack, and the dose was twice that of the others. She was seriously ill... I always felt that No way."

Xiao Lou stroked his chin, thoughtful.

Yu Hanjiang asked, "What do you think?"

Xiao Lou said: "Did Team Yu notice that the insulin that some old people take is not the same as what we found in the trash can?"

Yu Hanjiang nodded: "The insulin they bring is something like a ballpoint pen, which is the insulin pen you mentioned?"

Xiao Lou's right hand rested casually on the table, his slender fingers were slightly bent, and the tip of his index finger tapped the table lightly while carefully analyzing: "I have a classmate who is a doctor in the department of endocrinology. It is this 'insulin pen', which is convenient to carry, and also saves the trouble of drawing injections with a syringe."

He paused, and then said: "Insulin pens use thinner needles, which will reduce pain. There are obvious dosage marks on the pen, and the refill can be replaced at any time. When you go out, you only need to carry it with you.

It will be very convenient to bring enough refills and inject on time every day. "

In order for Yu Hanjiang to understand better, Xiao Lou gave an example: "This is like the difference between a 'ballpoint pen' and a 'traditional fountain pen'. For a ballpoint pen, if you run out of ink, you can just change the refill and continue using it. The refill is easy to carry. However, the pen needs to be removed from the pen. The ink is absorbed in the ink, it is not easy to control if it is absorbed more or less, and it is very inconvenient to carry ink with you, just like a traditional syringe, it will be more troublesome to absorb insulin and it is not easy to carry. Therefore, in clinical practice, "insulin pen" is basically used injection."

Yu Hanjiang, who had heard a lot of professional knowledge, immediately understood: "You mean, the traditional syringes and injections found in the trash can do not belong to Li Zhemin?"

Xiao Lou nodded: "That's right. Li Zhemin is so rich, and the insulin pen is very convenient to carry and use. It doesn't make sense that other old men and women know how to use insulin pens, and he even used the most outdated syringe to inject himself."

Xiao Lou picked up the ballpoint pen, quickly wrote out a formula in his notebook, and said, "There is one more question. I just thought about it carefully. The amount of insulin can be estimated according to this formula. Aunt Shu Ping is very thin and weighs up to 50 kg. , the daily insulin dosage is about 20U, and the insulin in her bag is enough for her to use for a month."

Yu Hanjiang looked down at the calculation formula——

[Fasting blood glucose (mmol/L)×18-100]×10×body weight (kg)×0.6÷1000÷2……

Xiao Lou's handwriting is meaningful and correct, such a long formula is thanks to him for remembering it.

Yu Han lowered his head and pondered for a moment, then speculated: "According to your analysis, the injections and syringes in the trash can do not belong to Li Zhemin, because the equipment used by Li Zhemin to treat diabetes must be a relatively advanced 'insulin pen' rather than traditional plastic ones. Syringe. However, we did not find insulin in Li Zhemin's bag, but Shu Ping's bag had more than normal doses of insulin. Therefore, it is very likely that Shu Ping stole all of Li Zhemin's insulin? !"

Team Yu's logic is perfect, and he understands Xiao Lou's meaning in seconds.

Xiao Lou nodded appreciatively, and said, "I asked tour guide Xiaoqin, their group of senior citizens, from departure to return, has a total of ten days, and the return journey is directly by plane. Auntie Shu Ping brings a month's worth of insulin refills, which is absolutely unnecessary. .”

A 10-day journey with a 30-day dose—that's a dose for two.

It seems that Lao Li has offended quite a few people, and this Shu Ping actually stole all his insulin!

Yu Hanjiang tidied up his thoughts and said, "Shu Ping looked ugly just now, and she didn't want us to check her bag because she stole Lao Li's insulin, for fear that we would find out—this woman has a serious problem."

Xiao Lou followed up and said, "However, the murderer who gave Lao Li about 300U of insulin with a traditional syringe at one time is not necessarily Aunt Shu Ping. If it was her, she didn't need to go to the trouble of stealing Lao Li's insulin Refill."

Yu Hanjiang agreed: "It seems that we need to continue the investigation. This senior group is really not easy."

At this moment, the tour guide Qin Shiyue came over with a stack of documents.

After psychological adjustment, the girl's complexion has improved a lot. She knocked on the door of the flight attendant's office, handed the information to Xiao Lou, and said: "Our travel agency has relatively high requirements for the registration of the elderly, and the registration form must be filled out in detail. Here are 12 people. Passengers' registration forms, including their family information, past medical history, are recorded."

Xiao Lou nodded to her: "Thank you."

Qin Shiyue was silent for a moment, then clenched her fists and said, "If it's really murder, we must find the murderer!"

"Don't worry, we will find out as soon as possible." Xiao Lou was concentrating on reading the information, and Yu Hanjiang said lightly, "Xiao Qin, I would like to ask you a few questions. How long have you been with these 12 people? Which one has a better relationship with Li Zhemin?"

Qin Shiyue frowned and thought for a while, then said: "I took them to play in Sun City for three days. Lao Li is very popular in the group, and most people like to flatter him. His son is very rich. Before In Sun City, he invited all of us to a high-end restaurant to eat a seafood feast, and he ate hundreds of thousands of dollars for a meal. He is also very loyal, and he will pat his chest to help anyone who asks him."

Yu Hanjiang said: "He didn't argue with anyone?"

Qin Shiyue shook her head: "During the few days I took them, everyone got along very happily, talking and laughing along the way, and nothing seemed unusual. Lao Li invited everyone to the dining car for dinner last night."

Yu Hanjiang asked: "Does no one hate him? For example, showing disgust in private?"

"This..." She scratched her head and thought for a while, then said, "It's more obvious that Uncle Niu hates him. He never talks to him, doesn't sit at the same table when eating, and meets him as if he doesn't know each other. By the way, there is also Shu Aunt Ping always rolls her eyes behind her back, I have seen Aunt Shu sneer when Lao Li praised her son many times."

Yu Hanjiang then asked: "The three in room 2, do they have the best relationship with Lao Li?"

Qin Shiyue nodded: "When I bought the tickets, the seats of the four of them were not together. Lao Li said that he wanted to play cards with the brothers, so he asked me to spend money to change the seats at the ticket office and put the four of them on the same bed. Change to the same room."

This is consistent with the investigation results in Room 2. The four old men did play cards until two o'clock last night.

Xiao Lou suddenly raised his head from the pile of documents, and asked additionally, "Did Lao Li sleep like a dead sleeper?"

Qin Shiyue was stunned for a moment, then nodded and said: "It seems so. Everyone said that he is kind-hearted. His son is so rich and filial to him. There are several houses in his house. He has nothing to worry about, so he sleeps soundly, and even thunderstorms Can't wake up."

After all, the time the tour guide has been in contact with this group of people is very short.

There wasn't much information, so Yu Hanjiang let her go after he understood the situation, and told her, "Please, call Shu Ping over."

Qin Shiyue turned around, went to Room 3 and called Shu Ping.

The youngest and most beautiful old lady in the regiment usually put on a proud look, but now her face turned pale.

She took a deep breath, and pretending to be calm, she came to the door of the flight attendant's office, and saw two people standing and sitting inside.

The sitting handsome guy has clear eyebrows and gentle eyes, and looks easy to get along with.

But the standing man's eyes were as sharp as ice and arrows. Shu Ping was so frightened that her legs trembled when she was swept away by his cold eyes. She was wearing very thin high-heeled shoes and nearly sprained her feet. , and then stabilized the body.

Yu Hanjiang said lightly: "Tell me, why did you steal Li Zhemin's insulin?"

Shu Ping: "..."

The author has something to say: Team Yu is good at playing straight balls. Aunt Shu said: I was scared to death.

The story gradually became clear. In front of criminal police and forensic doctors, all crime methods are paper tigers.

See you tomorrow!
