Yesterday at the scene, neither Liu Ya's parents nor her boyfriend mentioned that Liu Ya had a brother. Therefore, Yuan Chen and others only found out about such a person now.
"Can you tell me more specifically?"
"That's right, her brother has been to the company several times, so I've met him. As for their relationship, how can I put it? They quarrel almost every time they meet, and the curse words are very ugly. They don't look like a brother and sister at all.
.”
"Oh?" Yuan Chen blinked, obviously very interested in this topic.
"I heard that that brother is a scoundrel. He often messes around outside and is addicted to gambling. He treats Liu Ya as a cash machine. As soon as he loses all the money, he goes to his sister to ask for it. When Liu Ya sees him, she follows him.
Like a plague."
Listening to his description, this brother does not seem like a good person, but these are just his one-sided words, and the specific situation requires further careful investigation.
"Mr. Lu, do you remember what you drank that night?"
Lu Yong touched his chin with his hand.
"Drink... Yes, when I went there that day, Liu Ya originally wanted to treat me to some wine, saying it was imported red wine brought by a friend, and I..."
"She, a female subordinate, would take the initiative to invite you, a male leader, who comes to her home to discuss work for a drink, or late at night?" Hao Weida interjected.
He seemed to realize that what he said was inappropriate, and he scratched his head.
"She was also polite, and she probably just asked that, but I refused. After all, I had to drive back, so I had tea instead of wine, but she still drank it herself."
"Is there anything strange when she drinks?"
"No, at least I can't tell. And judging from the quality of the wine, it's indeed pretty good."
Yuan Chen sneered in his heart, if you knew that the wine was mixed with poison, I'm afraid you wouldn't say that.
"Oh, by the way, Mr. Lu, one more question, did you change into slippers when you arrived that day?"
"Well, of course, it's still a guest after all."
It seems that the pair of slippers at the door were specially prepared. No one should have touched them after Lu Yong left. This is logical.
"Then do you remember what color those slippers are?"
"This... police officer, I really don't remember such details. You can't blame me."
Yuan Chen nodded to express his understanding, "That's right. This kind of problem is indeed a bit difficult for you. Okay, let's leave it like this for now."
When Lu Yong left, he no longer felt as nervous as when he first sat here, and he felt much more relaxed. He may have felt that he had made a great contribution to the people's police officers and social security.
"How's it going? Do you have any ideas?"
Qian Cheng took a sip of water. The interrogation just now really made his mouth dry.
"This Lu Yong is not simple. I suggest you continue to follow up. You can go to the company where they work to understand the situation."
Qian Cheng nodded.
"This is natural. It was originally part of the investigation. However, since Lu Yong came out like this, we had to move ahead of time. In addition, her brother must be found as soon as possible."
"As for the lottery ticket, I think we can investigate among the friends around the deceased. It is impossible that there are no relevant insiders." Yuan Chen mentioned.
"What, do you think that lottery ticket was the murderer's motive for the murder?"
"It's not certain yet. It's just that the two things coincide so well that it's hard not to connect them."
"I know, I will arrange for someone to check."
After the division of labor among several groups, they all went their separate ways. Yuan Chen and Hao Weida returned to Liu Ya's home, where his parents were keeping vigil for her.
According to the information collected, Liu Ya does have a brother who is five years older than her, named Liu Wei.
"Officer Yuan, is there any news about my daughter?" The old lady was very excited when she saw Yuan Chen, which made him very awkward.
"Auntie, don't worry. We are here today mainly to get some information from you, which will also help us solve the case as soon as possible."
Seeing that the old couple had no objections, Yuan Chen started to ask.
"How is Liu Wei doing lately?"
"Why are you mentioning him? I haven't seen him for a long time." Mother Liu's expression was a little unhappy.
"This...he is your son."
"Forget it, I would rather not have this son."
Father Liu on the side also spoke, his tone even colder.
Hao Weida's face was also full of question marks. He didn't expect that the old couple would be so unkind to their son. It was indeed very rare.
"Can you tell us more about your son's situation? This is very important to us."
"Humph, that prodigal son didn't learn well since he was a child. He would steal money from home, Xiaoya's pocket money, and his classmates' watches at school. He was almost expelled from school for this. He really made us miserable.
His face was completely humiliated!
When he got older, he became even more promiscuous. He hung out with a bunch of shady people all day long, playing cards and gambling. When he ran out of money, he just asked us if we wanted it. If we didn't give it to him, he would go to Xiaoya. Xiaoya still gave it to him at first.
But when he stopped giving it, he started beating Xiaoya and his own sister..."
Mother Liu said, her nose became sore and she started crying again.
Yuan Chen and Hao Weida had no choice but to comfort them repeatedly.
"That treacherous son, he is nothing, nothing more than a human being!" Liu's father also shouted loudly from the side.
Such bad behavior is obviously not something a normal brother can do, let alone a normal man.
According to the address provided by Liu's mother, the two quickly found Liu Wei's home.
Liu Wei's image is quite different from Yuan Chen's imagination. He is very tall, very strong, has a beard, and is dressed very decently. He is completely different from the villain Liu's father and Liu's mother described.
According to the information, Liu Wei is the department director of a company, and his job can be said to be quite respectable.
It's hard to imagine that such a person would do such a bad thing to his sister.
In fact, for the same person, the impressions in the eyes of different people around him are often very different.
A murderer is not a good person legally, but in life, he may be a good father.
Similarly, a successful and famous boss may be no different from those prostitutes who frequent nightclubs in private.
Duality is what a complete person should possess.
The same is true for Liu Wei. In career and life, his identity is completely different. Naturally, his labels are also different.
Now, even if the police officer comes to his door, he seems to have no fear.
"Mr. Liu Wei, you should already know the news about your sister's murder, right?"
"I know, he died the night before yesterday." His tone was very calm.
Yuan Chen showed a subtle expression. Regarding Liu Ya's death time, they did not announce it to the public.
Hao Weida was about to speak, but Yuan Chen held him down.
"How can Mr. Liu be so sure that your sister was killed at night?"
"You're guessing, what's the point?" He answered casually.
"My guess is pretty accurate." Yuan Chen smiled.
"Mr. Liu, could you please tell me where you were and what you were doing between 8 and 10 pm the night before yesterday?"
"Are you investigating my alibi?" he asked rhetorically.
"It's just a routine inquiry, Mr. Liu, don't be nervous."
Liu Wei thought for a while, "I was working overtime that night and didn't leave until about 11 o'clock in the evening. I had never left the company before."
Such a statement can be confirmed as long as the monitoring is called, and there is no doubt.
"Mr. Liu, how is your relationship with your sister?"
"What is a relationship? I'm his brother."
"But as far as I know, you once beat her..."
"Mr. Police Officer, are you doubting me? Is there anything abnormal about fighting between brothers and sisters?"
