When Captain Yu was interrogating just now, Xiao Lou had been taking notes. He wrote down everyone's confessions verbatim. After Zheng Weiguo left, Xiao Lou asked: "Who is the murderer that Captain Yu is more inclined to believe?"
"
Yu Hanjiang picked up the record book and said while reading: "At present, Zheng Weiguo and Liu Yuming are more likely to be suspected. First of all, they are all in Room 2. It can easily confirm whether Li Zhemin is asleep as long as the other three are asleep.
, once the door is closed, no one will discover the crime; secondly, both of them have motives for killing; thirdly, there are obvious loopholes in their confessions."
He put the notebook on the table and pointed at a line of records: "Zheng Weiguo said that he found Li Zhemin's body in the morning and stole the IOU - how did he know that Li Zhemin would take the IOU with him? Who goes on a trip?
Will you bring an IOU?"
Xiao Lou's eyes lit up: "Yes, under normal circumstances, things like IOUs are kept at home and taken out when needed. No one will carry them with them."
Yu Hanjiang nodded: "The only explanation is that Zheng Weiguo asked Li Zhemin to bring the IOU on this trip. Perhaps, he lied to the other party and said that he would repay the money and wanted to tear up the IOU in person. In this way, Li Zhemin would naturally bring the IOU with him."
IOUs have a special function. They are written when borrowing money and torn up in person when repaying money. This is also a business rule.
Yu Hanjiang's speculation was very reasonable. Only when Zheng Weiguo took the initiative to ask Li Zhemin to pay back the money would Li Zhemin bring the IOU and tear it up in front of him after he paid back the money.
Xiao Loudao: "What Captain Yu means is that Zheng Weiguo's stealing of the IOU was not accidental, but premeditated?!"
Yu Hanjiang's eyes were deep and he analyzed in a low voice: "Zheng Weiguo knew that Lao Li loved to play cards with them, so he made up an excuse in advance for Lao Li to bring the IOU. During this trip, he secretly stole the IOU, and Lao Li lost the IOU.
, he can just pretend to delay and refuse to admit his debt."
Xiao Lou followed the train of thought and analyzed: "Perhaps Zheng Weiguo also confirmed where Li Zhemin's IOU was before getting in the car?"
Yu Hanjiang nodded: "Obviously, he knew very well that the IOU was in Lao Li's pocket."
Xiao Lou frowned slightly: "In this way, Zheng Weiguo's suspicion was very high. He was worried that the matter would be exposed after stealing the IOU, so he simply killed Li Zhemin. He thought that only he and Lao Li knew about the loan. As long as he
Once Lao Li dies, he won't have to pay back the money, and he won't be suspected. I didn't expect that Liu Yuming, who was in the same room, would accidentally see this IOU."
Yu Hanjiang said: "Moreover, Liu Yuming knew that he was addicted to gambling and divorced his wife. His seamless plan was helplessly exposed."
The two were silent for a moment - if the murderer was really Zheng Weiguo, his motive for the murder was very clear, plus he was a diabetic and knew the safe dosage of insulin; it was easy to confirm whether the deceased was asleep in the same room, and he had sufficient time to commit the crime.
Is it really that simple?
Yu Hanjiang always felt that something was wrong. He thought for a while and said: "Zheng Weiguo would definitely tear it up immediately after stealing the IOU. We did not find the fragments of the IOU. It means that there is only a witness and no physical evidence. If it was really the person he killed, he could have bitten it."
Even if he refuses to admit it, there is nothing we can do against him."
There is no way to convict someone based on witness evidence alone, because people can lie.
If Zheng Weiguo is really the murderer, his most correct thing to do is to insist on "I don't know the IOU" and let Liu Yuming's identification become a false accusation. Anyway, another insider Li Zhemin is dead and there is no proof.
Xiao Lou was confused: "We didn't find any scraps of paper in the trash can. Where did the IOU go?"
Yu Hanjiang thought for a while and suddenly said: "Maybe he put it in his mouth?"
Xiao Lou: "..."
Yu Hanjiang had encountered such a murderer before. In order to destroy the evidence, he ate the paper ball and couldn't find anything after digesting it in his stomach.
If Zheng Weiguo's confession is correct, it was 7 o'clock in the morning when he woke up. Some elderly people had already gotten up. It was too obvious for Zheng Weiguo to throw away the garbage. Therefore, the most reasonable thing to do was to swallow the torn note into his stomach. Even the gods were looking for it.
Less than.
Xiao Lou helplessly held up his forehead: "Captain Yu is right. If the IOU is eaten, no one will be able to find it. Why should he admit it?"
Yu Hanjiang said: "From the perspective of criminal psychology, what he did was a bit like 'a dog jumping over the wall' - because he was too suspicious, so in order to clear himself of the crime of murder, he admitted to stealing. If he stole the IOU, the penalty would be much lighter.
Murder is punishable by death."
The suspicion of Zheng Weiguo cannot be ruled out, but it cannot be confirmed either.
Xiao Lou asked with a headache: "What about Liu Yuming? His vulnerability is... digging through the trash can in the middle of the night?"
Yu Hanjiang said: "It's such a ridiculous excuse to get up in the middle of the night and dig through the trash to find a watch. They played cards until 2 a.m. before going to bed. Most people would check the time before going to bed. He should have discovered that the watch was missing at that time. Why didn't he search for it?
Instead, I slept for an hour and then sneaked through it at three o'clock?"
Xiao Loudao: "What he said is that he was afraid that he would be embarrassed if someone saw him going through the trash can."
Yu Hanjiang said: "Who will see it? At 2 o'clock in the morning, everyone except them night owls is asleep. He can wait for the three roommates to go to bed, close the door, pretend to go to the toilet, and find the watch.
"
In any case, I found out that my watch was missing at 2 a.m., took a nap, and got up to look for it at 3 a.m. No explanation is reasonable.
Xiao Lou dug out Liu Yuming's registration form from a stack of information.
He filled in the information in the "spouse" column. His wife has left this company and works in another company. He also has a son who is 25 years old, unmarried, and works as a doctor.
From this point of view, Liu Yuming's suspicion is also very high. His son is a doctor. Even if he does not have diabetes, he can ask his son to find out about the dangers of excessive insulin injection for diabetic patients. Moreover, it will be very difficult for him to ask his son to help buy syringes and insulin injections.
convenient.
It's just that he now has a wife, a son, and a happy family. Is it necessary to kill someone for the sake of an old incident that was stolen more than 20 years ago?
Yu Hanjiang thought for a while and said: "The current accident is in Car No. 6, and our investigation has been limited to Car No. 6. Since we are arranged to manage two carriages separately this time, maybe there will be clues in Car No. 4.
.”
Xiao Lou nodded in agreement: "Let's do that. I'll go to Car No. 4 and ask... By the way, little Yu Xinxin fell asleep at ten o'clock last night. Maybe she woke up in the middle of the night and found something."
Yu Xinxin's family will get off the bus tonight and not go to the terminal. Obviously, it has nothing to do with the case, but the little girl plays a lot of roles in the plot of the secret room, and there may be clues there.
Thinking of this, Xiao Lou stood up and said to Yu Hanjiang: "Captain Yu, I'm going to ask Yu Xinxin first, and I'll see you later."
Yu Hanjiang nodded: "Okay, be careful."
The two of them acted separately.
Xiao Lou went to Car No. 4 to find the child Yu Xinxin, while Yu Hanjiang continued to interrogate other elderly people.
He called over "Sister Mei" in Room 1, whose ears were not very good.
The old woman's real name was Mei Ruohua. When she was young, she was the head of the company's human resources department and was responsible for recruiting people. Yu Hanjiang knew that her ears were not good, so he simply took a pen and paper and wrote a question in a notebook: "Aunt Mei, how is your relationship with Li Zhemin?"
Grandma Mei wore thick reading glasses and a magnifying glass. She leaned in front of the book and read the words carefully. After reading it, she said: "Xiao Li? I personally recruited him into the company. He is not highly educated, but
This young man is very smart and learns things very quickly."
Yu Hanjiang: "When he first joined the company, which department was he assigned to? Who took him?"
Grandma Mei said: "He is an intern in the company's sales department. Niu Dapeng took him under his guidance. Niu Dapeng is half of his master."
Yu Hanjiang continued to write: "He went after the boss's daughter and took Niu Dapeng's position as manager. Have you heard of this?"
The old lady nodded: "Well, of course I know, everyone in the company knows."
Yu Hanjiang quickly wrote: "Did any accidents happen while he was chasing the eldest lady?"
Grandma Mei sighed, coughing and said: "Well, it's a long story. I watched Ruirui grow up. I am ten years older than her, and she was like my biological sister. At that time,
Liu Yuming is chasing her. They have known each other since college. Liu Yuming is handsome and has good looks.
Ruirui has been attracted by her talent for a long time, but Ruirui is a reserved child and is embarrassed to fall in love in the company. I also encouraged her at the time that girls should be more proactive. She was originally going to agree, but a week later, she suddenly cried
She came to me and said she was... raped by someone."
Yu Hanjiang stopped writing for a moment, frowned and said, "Being raped?"
Grandma Mei shook her head: "It's not that serious. It was Xiao Li's birthday that day and he invited many young girls to his house for a party. He knew how to cook. The girls all wanted to try his craftsmanship, so they went together.
Of course, drinking is inevitable at the dinner table, and Ruirui also drank some wine. She can't drink well. She doesn't know anything when she's drunk. When she wakes up...well, drinking is really harmful!"
Yu Hanjiang finally understood now.
Why did the eldest lady and Brother Liu suddenly change their minds and marry Li Zhemin when they were about to move forward?
It turned out that this was Li Zhemin's fault - he had long planned to rely on his boss's daughter to get to the position, and deliberately coaxed several young girls to go to his house to play. Maybe he had drugged the eldest lady's wine, and took advantage of a group of people to drink.
He was drunk and slept with the eldest lady.
Grandma Mei followed closely: "That's when Ruirui got pregnant. She felt very embarrassed and embarrassed to be with Liu Yuming again. In addition, Xiao Li felt very sorry for her and vowed to be good to her. She felt
Frustrated, he quickly married Xiao Li and held the wedding within a month. Xiao Liu was very sad at the time, alas..."
"Ahem, cough, cough..." Grandma Mei coughed and sighed: "Only Ruirui's father and I know about this matter. Xiao Li really went too far. He said he was drunk and didn't know. I don't believe it anyway!
I've been there too, and when a man is really drunk, he's like a puddle of mud. Can that thing stand up when his mind is not clear?"
Yu Hanjiang: "..."
Although the old lady's words were a bit direct, as a man, Yu Hanjiang agreed with her point of view.
It is impossible to have such impulses if you are completely drunk and lose consciousness. Only in a half-drunk state can you use wine to strengthen your courage - not to mention that Li Zhemin is probably not drunk and deliberately slept with the eldest lady. In order to climb up, he will do whatever it takes.
Yu Hanjiang followed up by writing: "How is Li Zhemin's wife, Ruirui, doing now?"
Grandma Mei's eyes suddenly turned red: "Ruirui, this girl has a really hard life... Half a year after she got married, her father died of lung cancer and left the company to her only daughter. She was pregnant at the time and couldn't manage the company, so she had to
Let Li Zhemin help take care of it. She had a difficult delivery when she gave birth, and her health has been poor. Within two years, she suffered from postpartum depression and passed away."
So, the entire company fell into the hands of Li Zhemin?
Yu Hanjiang picked up the information form and saw that Li Zhemin's "spouse" column did not say "died of illness", and his spouse's name did not contain the word "rui". He then thought about it and asked, "Li Zhemin married a second wife?"
Grandma Mei said angrily: "This Xiao Li has been misbehaving! Not long after Ruirui left, he got together with a young and beautiful nurse. Within a year, he married the nurse as his wife. His son was still young at the time.
, I didn’t even know that this mother was actually a stepmother!”
Yu Hanjiang: "..."
Grandma Mei continued: "By the way, he and his second wife also gave birth to a son, who is studying in college."
Yu Hanjiang lowered his head and saw that this was consistent with the information sheet. Li Zhemin currently has two sons, one with his ex-wife Ruirui and the other with his current wife.
Yu Hanjiang made a detailed record of what the old lady said and asked her another question: "You are the oldest employee in the company. Do you know who organized this trip?"
Grandma Mei said: "It was organized by Li Zhemin's son."
Yu Hanjiang raised his eyebrows in surprise: "Oh? Is it related to his son?"
Grandma Mei said: "His son graduated a few years ago. Li Zhemin safely handed over the company to his son and retired early to enjoy his life. His son is indeed very promising. After taking over the company, the business was booming and he made a lot of money.
He made a large sum of money, and then went into real estate. It is said that he developed a real estate some time ago and made billions in net profits, so he took the initiative to spend a sum of money and invited retired employees of our company to take a trip for free, which was regarded as a gift.
Our welfare."
Yu Hanjiang's brows frowned more and more, and he quickly wrote down the last question: "His son paid for everyone to travel. How did you know about this?"
Grandma Mei said: "The HR director of the company is a new girl who doesn't know much about retired employees. She came to consult with me, the former manager. I asked her what she was doing. She said that the boss asked her to make statistics and pay benefits to old employees...
Isn’t this free travel a welfare?”
Yu Hanjiang lowered his head and thought for a moment.
Grandma Mei probably talked too much and got a little excited. She covered her chest and started coughing desperately. The dry cough was heart-wrenching to hear. She probably suffered from asthma and couldn't talk too much. Neither did Yu Hanjiang.
In order to seize the time of asking the seventy-year-old old man, the parents temporarily let her go.
***
In Car No. 4, Xiao Lou walked up to Yu Xinxin's child with a smile and said, "Xinxin, uncle has a few questions to ask you, is that okay?"
Yu Xinxin liked this uncle with a gentle smile very much, and immediately nodded and said: "Okay!"
Yu Xinxin's mother was not at ease about handing over her daughter to a stranger. There was obvious hesitation on her face. Xiao Lou followed up and said: "You can go to the office with me. Don't worry, I just want to ask your daughter a few questions."
The woman then breathed a sigh of relief, hugged her daughter and followed Xiao Lou.
Xiao Lou came to the steward's office in Car No. 4. The woman carried Yu Xinxin in, with a nervous look on her face: "What happened? I heard someone screaming in Car No. 6, and the door was locked."
Xiao Lou said: "It's nothing. Two old people had a dispute. The flight attendant is handling it. Don't worry." He looked at Yu Xinxin with a smile and said: "Xinxin, did you sleep well last night? I think you fell asleep at ten o'clock.
, have you ever woken up in the middle of the night? Children can't lie, tell your uncle the truth."
Yu Xinxin glanced at her mother and replied seriously: "I woke up at 3:30 in the middle of the night and wanted to go to the toilet, but my mother was sleeping, so I didn't wake her up and went to the toilet alone!"
Xiao Lou praised: "Xinxin is really sensible."
Her mother said happily: "This child has been sensible since he was a child. He has never let us adults worry about things like going to the toilet and getting dressed."
Xiao Lou gently touched the child's head and asked softly: "When you went to the toilet, did you see anyone walking around in Car No. 6, or hear any strange noises?"
Yu Xinxin bent her eyes and smiled: "Yes, an old woman also went to the toilet, and she kept coughing!"
