Chapter 73 Chapter 6 Suspect
The two sorted out the evidence and returned it to the flight attendant's office in front of the train. Xiao Lou looked at the syringe and empty bottle on the table and thoughtfully asked, "Yu, can we search the passengers' backpacks directly? Should they still There are some clues. "
Yu Hanjiang thought for a while and said, "I remember the 3rd room of the Red Peach. When the students went to the playground, we went to the classroom to search for 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." Simply said, "Go and try it."
Xiao Lou nodded and turned to follow Yu Hanjiang.
The two came to Room 1, Yu Hanjiang said calmly, "At the request of the security department, we need to carry out a simple security check on your luggage. Please cooperate."
The passengers did not object, it seems that they take the security check of the flight attendants as usual.
An old man came over and asked Xiao Lou, "Is Li guilty of a heart attack?"
Xiao Lou smiled and said, "There is no firm conclusion yet, uncle, please give me your backpack."
The old man handed him the bag cooperatively and said, "I didn't bring any flammable or explosive products, and all the food was in the bag."
Xiao Lou opened it and took a look--it really ate a large package. The old man was a foodie.
He asked, "How many days will you stay in the city of the moon 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 shoulder travel backpack purchased by the travel agency uniformly. There was a luggage tag on the backpack with everyone's name written on it to avoid making mistakes.
Yu Hanjiang checked baggage on the grounds of "security inspection", and the other three took the backpack in cooperation.
The old lady in bed 1a is still reading her newspaper with her head down. This old lady is over 70 years old, her hair is all white, her waist is bent, her face is wrinkled, she walks with a cane, and her ears are problematic. Everyone else takes care of it. She called her "Mei Mei".
Seeing that she didn't respond, an old lady next to her shook her arm gently. "Sister Mei, the flight attendant wants a security check."
Sister Mei was shaken a little, raised her head and asked, "What?"
The old lady shouted in her ear loudly, "The flight attendant wants to check the luggage!"
Sister Mei still looked blank. "What?"
Yu Hanjiang pointed at her backpack and asked her to take it down. She finally understood the gestures and stood tremblingly to get the bag. The old man next to her saw that she had trouble moving and helped her.
Yu Hanjiang opened her backpack and took a look. There were a few old clothes changed, some antihypertensive drugs, 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 bright. She is the oldest senior in our unit. Since the entrepreneur started, she has been in the company's personnel department. Most of us recruited her into the company. Yes, her daughter asked her to come out with us to relax, and she was unwilling to find it difficult to go out. "
Xiao Lou and Yu Hanjiang looked at each other. Since this sister Mei is the oldest employee in the company, she will definitely know something.
Her luggage was normal, and Yu Hanjiang planned to ask her a question alone. I can't hear my ears and can write. The old man is wearing a thick reading glasses, should he be able to read the characters clearly?
These two backpacks are okay. The remaining two, Xiao Lou and Yu Hanjiang, also quickly inspected separately.
Yu Hanjiang found some needles, cotton swabs, and a row of ball-point pens in one of his backpacks. He didn't know, and showed it to Xiao Lou. After Xiao Lou had looked carefully, he whispered in Yu Hanjiang's ear, "This is an insulin pen."
Yu Hanjiang turned the name on the backpack luggage tag-Niu Dapeng.
He looked at the old man in c-bed No.1 and asked, "Uncle Niu, is this bag yours?"
Niu Dapeng nodded. "Yeah."
Xiao Lou smiled and asked, "Do you also have diabetes?"
Niu Dapeng said, "I have had this problem for many years and have been relying on insulin control."
Yu Hanjiang then asked "Do you know Li Zhemin has diabetes?"
Niu Dapeng calmly said, "Know, I've been in the same hospital with Lao Li before."
Yu Hanjiang wrote down this old man named Niu Dapeng.
The last package found no exceptions. The two left room 1 and continued their search.
Since the deceased lived on the 2nd, this room needs to be checked.
The old man sleeping on the upper bunk with the deceased happened to be the most obvious baldness in this group. His head had only half of gray hair and was highly recognizable. The man's name was Zheng Weiguo, and Yu Hanjiang found the same needle, cotton swab and insulin pen in his bag.
Yu Hanjiang asked, "How long have you been diabetic?"
Zheng Weiguo looked embarrassed. "I didn't pay attention when I was young. I often eat big fish and big meat. I checked out diabetes and high blood pressure five years ago. I have been using insulin and antihypertensive drugs to control it."
In addition, Yu Hanjiang also found a deck of playing cards in an old man's bag named Liu Yuming. The other side explained, "Lao Li loves playing cards. The four of us played upgrades last night, and 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 fell in love with the toilet in the middle of the night, and my eyes are not good, and I can't see clearly at night. This time when I went out, my son prepared a rechargeable lamp for me, and made me want to go to the toilet with the lamp. Yesterday Late at night, Lao Li wanted to play cards, so I turned on the charging lamp and put it on the upper deck. "
The other two nodded, "Yes!" "Old Li was very happy when he played cards last night. I didn't expect ... hey."
This group of elderly people, even playing with rechargeable lights and playing cards until 2 am, is enough.
Yu Hanjiang asked him, "Did you go to the toilet last night? Did you see anything?"
Liu Yuming shook his head. "I got up once at three o'clock. Everyone was sleeping. All the doors were closed."
Yu Hanjiang said, "Did Li Zhemin move at that time?"
Liu Yuming thought about it and said, "I remember Lao Li seems to have rolled over, still snoring softly."
In other words, Li Zhemin's death time was after 3 am.
There were no other suspicious exhibits in this room. The two came to Room 3 and were about to check their luggage. As a result, an old lady suddenly said angrily, "What right do you have to search my luggage? This is a violation of privacy!"
Her mood looked extremely excited.
The old lady is called Shu Ping. She is 60 years old, but she looks like she is only 40 years old. Her skin and body are very well maintained. The beauty-loving old lady was wearing a skirt, and her shoulder-length hair was still hot. She was the youngest and most beautiful old lady in the group.
Yu Hanjiang said calmly, "Routine security inspection, please aunt to cooperate."
Xiao Lou echoed Yu Hanjiang with a smile. "Yes, everyone else cooperates with the inspection. If you are worried about privacy, you can follow us alone to the office and we will check it for you in private."
Shu Ping turned pale, holding her bag unwilling to let go.
Her weird performance caused the other three old men in the same room to stare. Yu Hanjiang frowned. "If you don't cooperate, then I can only control you temporarily and wait for the guard to handle it."
He reached out for the other's backpack, and Shu Ping gave it to Yu Hanjiang after a long struggle.
Yu Hanjiang opened it and took a look. In addition to changing the laundry, insulin was found again in the dark grid at the bottom of the backpack ... But, this dose is too much, right? Almost twice as much as Niu Dapeng and Zheng Weiguo's backpack.
Seeing them find out, the old lady's face suddenly became extremely ugly.
Xiao Lou smiled and asked, "Auntie, how many years have you been diabetic? Why bring so many medicines?"
Shu Ping grabbed her backpack and said with a calm face, "I found out last year. I have a more serious illness, and I use a lot of medicine, so I bring more medicine than the average person."
The old lady next to her looked at her in surprise. "Xiao Ping, you have diabetes too? Why didn't you tell us?"
Another humane "Yes, diabetes is not a shameful disease, many elderly people will have it, why do you hide it from everyone."
Shu Ping's complexion was blue and white, and she could not answer for a long time.
Xiao Lou and Yu Hanjiang exchanged a look and turned to leave the room.
Other passengers also cooperated with the inspection, but most of them had nothing to do with the elderly group, and their luggage was full of food and clothes.
After checking the whole car No. 6, the two returned to the flight attendant's office in front of the car.
The space above the train is limited. The flight attendant's office is only about 15 square meters. There is a small table and a chair. The two big men are standing slightly crowded, and their bodies are almost close to each other.
Yu Hanjiang is not accustomed to being so close to people, talking too close, breathing will brush on the other's face, which is very impolite.
He offered to offer, "Professor Xiao, sit down."
Xiao Lou was also very polite and sat down on a chair so that Yu Hanjiang's space would be relatively spacious. Xiao Lou looked up and looked at Yu Hanjiang who was standing beside him and asked, "What does Yu team think?"
Yu Hanjiang leaned on the table, his legs crossed at will, his hands were wrapped around his chest, and he whispered, "At present, there are four clear suspects-Niu Dapeng in Room 1, who had previously been in hospital with the deceased. He must be very aware of the diabetes of the dead in the same hospital. "
"Zheng Weiguo in Room 2 slept with the deceased on the bunk. He played cards together until two in the morning last night. It was easy for him to know if the other people in the room were asleep. It was convenient for Li Zhemin to fall asleep, and he was also a diabetic . "
"Liu Yuming in Room 2 said that he often used the toilet in the middle of the night, but it may also be a cover up. He killed Li Zhemin at 3 am, pretended to be in the toilet, and lost the syringe and insulin bottle, so that no one was there. Would doubt him. "
"There is also Shu Ping in room 3. When searching for luggage, the old lady was a little emotionally disturbed. Insulin was hidden at the bottom of the backpack, and the dose was twice that of other people. She was seriously ill ... Nowhere. "
Xiao Lou felt his chin thoughtfully.
Yu Hanjiang asked, "What do you think?"
Xiao Lou said, "Did the Yu team notice that the insulin that several elderly people took was different from what we found in the trash?"
Yu Hanjiang nodded. "The insulin they bring is similar to a ball-point pen. Is that what you call an insulin pen?"
Xiao Lou's right hand was placed on the table at will, and his slender fingers were slightly bent. The forefinger's fingertips gently tapped on the table while carefully analyzing "I have a classmate who is a doctor in endocrinology. At present, the most commonly used treatment of diabetes is This 'insulin pen' is convenient to carry, and it also saves you the trouble of taking an injection with a syringe. "
He paused, followed closely by saying "Insulin pen, the needle used is thinner, which will reduce the pain. The pen has obvious dosage markings, and the refill can be changed at any time. As long as you go out, you need to bring enough refills, and you will be on time every day. The injection will be very convenient. "
In order to make Yu Hanjiang better understand, Xiao Lou gave an example: "This is like the difference between a" ball pen "and a" traditional fountain pen. "Ballpoint pens can be replaced with a refill, and the refill is easy to carry. However, the pen needs to be replaced with ink. It the ink, it ’s difficult to grasp more and less, and it ’s very inconvenient to carry the ink with you. Just like the traditional syringe, it will be more troublesome to the insulin and it ’s difficult to carry. So clinically, it is basically injected with the
insulin pen
. . "
After hearing a lot of professional knowledge, Yu Hanjiang immediately came to understand. "Do you mean that the traditional syringes and injections found in the trash cans do not belong to Li Zhemin?"
Xiao Lou nodded. "That's right. Li Zhemin is so rich. The insulin pen is easy to carry and use. It doesn't make sense that other old men and old women know to use insulin pens. He also uses the most backward syringe to give himself an injection."
Xiao Lou picked up the ballpoint pen and quickly wrote a formula in the book, saying "There is still a problem. I just thought about it a bit. The insulin dosage can be estimated according to this formula. Aunt Shu Ping is very thin and weighs up to 50 kg. Counting the daily dose of insulin is about 20u. The amount of insulin in her bag is enough for her to use for one month. "
Yu Hanjiang looked down at the calculation formula
[Fasting blood glucose x06 ÷ 1000 ÷ 2 ...
Xiao Lou's handwriting is always upright, thanks to his long formula.
Yu Han bowed his head and pondered for a moment, speculating, "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 for the treatment of diabetes must be a more advanced 'insulin pen', not a traditional plastic syringe . However, we did not find insulin in Li Zhemin's bag. Instead, more than the normal dose of insulin appeared in Shu Ping's bag, so it is likely that Shu Ping stole all of Li Zhemin's insulin ?! "
Yu team logic full score, seconds understand the meaning of Xiao Lou.
Xiao Lou nodded in appreciation and said, "I asked the tour guide of Xiao Qin. They are an elderly group. There are ten days from the departure to the return journey. The return journey is a direct flight. Aunt Shu Ping brought a refill of insulin for one month. It was not necessary at all. "
A 10-day journey with a 30-day dose-this is a dose for two people.
It seems that there are many people who have offended Li. This Ping Shu actually stole his insulin!
Yu Hanjiang sorted out her head and said, "Shu Ping just looked ugly. She didn't want us to check her bag because she stole Lao Li's insulin and was afraid we would find out that this woman has a big problem."
Xiao Lou followed closely. "But, using a traditional syringe for Lao Li, the murderer who shot about 300u insulin at one time, may not be Aunt Shu Ping. If it is her, she does not have to do more to steal Lao Li's insulin pen. core."
Yu Hanjiang agreed that "it seems that we still have to continue the investigation, this elderly group is not easy."
Just then, the guide Qin Shiyue came over with a stack of information.
The girl has undergone psychological adjustment, and her face has improved a lot. She knocked on the door of the flight attendant's office and passed the information to Xiao Lou, saying, "Our travel agency has higher requirements for the registration of the elderly. The registration form must be filled in. Here are 12 passengers. Registration forms, including their family information and past medical history, are recorded. "
Xiao Lou nodded to her "Thank you."
Qin Shiyue was silent for a moment, and clenched his fists, "If it is really murder, you must find the murderer!"
"Rest assured, we will definitely find out as soon as possible." Xiao Lou was looking at the information intently, and Yu Hanjiang said lightly. "Xiao Qin, ask you a few questions. How long have you taken these 12 people? Which ones have a better relationship with Li Zhemin?"
Qin Shiyue frowned and thought, and said, "I took them to play in the City of Sun for three days. Old Li is very popular in the group. Most people like to make him fart. His son is particularly rich. He asked us all to go to a high-end restaurant for a seafood meal, and we ate hundreds of thousands at a meal. Others were also very moral, and whoever asked for him would pat his chest to help. "
Yu Hanjiang said, "He has not argued with anyone?"
Qin Shiyue shook his head. "These few days I took them, everyone was very happy. They talked and laughed along the way. It looks nothing abnormal. Yesterday, Li Li invited everyone to the dining car."
Yu Hanjiang asked, "Does no one hate him? For example, showing offensive emotions in private?"
"This ..." She scratched her head and thought for a while, and said, "Uncle Niu hates him more obviously. He never talks to him, and doesn't sit at a table for a meal. It's like meeting someone if he doesn't know it. By the way, there is Shu Ping Auntie, always rolling her eyes behind me. I have seen many times. Auntie Shu sneered when Li Kua's son was old. "
Yu Hanjiang then asked, "Is the three in Room 2 the best relationship with Lao Li?"
Qin Shiyue nodded. "When buying a ticket, some of their seats were not together. Lao Li said that he had to play cards with his brother. He specifically asked me to pay for the seats at the ticket office to replace the seats. They changed their four beds. In the same room. "
This is in line with the results of the survey in Room 2. The four old men did play cards to two last night.
Xiao Lou suddenly lifted his head from the data pile and asked, "Is Li Li sleeping so hard?"
Qin Shiyue nodded, and then nodded, "It seems to be. Everyone said that he was broad-minded. His son was so rich and filial to him. There were several suites in the house. He had nothing to worry about. Don't wake up. "
After all, the tour guide's contact time with this group of people was very short, and she didn't know much information. Yu Hanjiang probably let her go back after knowing the situation, and told her to "trouble you, call Shu Ping."
Qin Shiyue turned and called Shuping to Room 3.
The youngest and beautiful old lady in the group always showed a proud look, but she turned pale at this time.
Taking a deep breath, she pretended to come to the flight attendant's office calmly, and saw two people standing and sitting inside.
The sitting handsome guy has a clear-eyed look, a gentle look, and looks good at getting along.
The man who stood, sharp eyes like ice, was swept away by his cold eyes, and Shu Ping shook her legs. She was wearing very thin high heels and almost stomped her feet. She hurriedly supported the doorknob next to her. This stabilizes the body.
Yu Hanjiang said, "Say, why steal Li Zhemin's insulin?"
Shu Ping "…………"
