Chapter 29 4. The person standing opposite

Chen Xiang remembered what happened last time, smiled and said, "How did he die? Oh, I'm asking what poisoned him to death?" Yu Zheng said, "It's arsenic poisoning." "arsenic?" "It's commonly known as arsenic." "Arsenic? I've only seen it in TV novels before. It turns out that people really use it to kill people, but where did this stuff come from? Shouldn't we start with the source of the poison?" Yu Zheng glanced at her approvingly: "You are really a little clever, but it is useless in this case. In theory, pure arsenic is naturally difficult to get rid of, but in fact it is not too difficult. It is made of a kind of arsenic. The white crystals extracted from arsenic-containing ores are odorless and have many uses, such as the glass industry, pharmaceutical production, and even household insecticides and herbicides, so we can’t find a clear clue from the source of the poison.”

"Oh." Chen Xiang nodded, thought for a while and said, "But why do I always feel that you already have a general scouting direction, do you start with the people around him?" "Yes," Yu Zheng said, "the reason for this kind of poisoning case is not too simple, it is not as clear as those robbery, fighting and murder cases, and the murderer must have thought carefully, and the reasons and methods have been dealt with accordingly , is hidden very deep, sometimes even if you know who the murderer is, you can’t find his motives and methods at all, like an invisible thread, one end is you, the other end is the murderer, if you want to catch him , you have to unravel and find this thread.”

"So complicated?" Chen Xiang was speechless. "My head hurts." "It hurts." Chen Xiang nodded: "But I like it. Last time, didn't you say that his wife is very suspicious? Let me guess which one is his wife, and see who is the one standing opposite you ..." Yu Zheng watched Chen Xiang look around at the photo of the Liang sisters in front of the whiteboard amusedly. After turning around for a while, she raised her head and pointed to the photo of Liang Xiaoyun and said, "That's her." Yu Zheng asked a little strangely: "Is this also based on your intuition?"

"right." "Tell me why." Chen Xiangyi treated you like an idiot: "Is it called intuition if you can tell the reason? Just say it right." "Even if your woman's intuition is strong." Yu Zheng picked up the information in his hand and said: "She is indeed the biggest suspect we suspect now, but we can't find a motive or a method of killing. I have read the information several times, but there is no valuable clue.” "What about the rest?" "Of course, other suspects cannot be ruled out." He said, walked to the whiteboard, picked up a pen and wrote down the names of the Liang sisters under the photo, and then wrote the general information on it, saying something in his mouth: "Liang Xiaoyun, 29 years old, flight attendant, married four years ago, Li Jianbin The biggest beneficiary after the death was not in Qingdao when the crime happened. Liang Xiaoyu, younger sister, graduated from Qingdao a year ago and came to Qingdao to develop, but has not found a job. She lives in her sister’s house. On the surface, Li Jianbin should have been alone at home when he died, but the autopsy report stated that he had sex before his death."

"Having had sex means having an affair? Then who spent the night with him?" Chen Xiang said. "Does Liang Xiaoyun know?" Yu Zheng shook his head: "Everything is still to be investigated, but it seems that we have to investigate from the two sisters of the Liang family first." "When will you go? Count me in." Yu Zheng frowned and said, "Aren't you tired? You really have plenty of energy." "Why are you tired? Anyway, I'll be alone when I go back, so I might as well go out and find some material." Chen Xiang lowered his head and said listlessly.

Yu Zheng's heart softened immediately, thinking that it would not be easy for a girl to go out alone: ​​"Okay, I will call you when I go." "You keep your word, don't leave me alone." Chen Xiang immediately cheered up, shaking his head with a smile. Yu Zheng immediately felt cheated. But men have to keep their word. When they went to Li Jianbin's house, Yu Zheng still called Chen Xiang, and Liu Gang and the three went together. Liang Xiaoyun was not at home, and a woman about 25 years old opened the door for them. Yu Zheng immediately recognized her as Liang Xiaoyun's younger sister, Liang Xiaoyu.

Liang Xiaoyu was obviously not in good condition, her eyes were red and swollen, her cheeks were thin and her cheekbones protruded. She looked extremely haggard, but she wore heavy makeup, dark eye shadow and dark red lipstick. They walked into the living room, sat on the sofa naturally, crossed their legs, and lit a cigarette. Yu Zheng sat across from her and said, "Miss Liang, where were you the day your brother-in-law was killed?" "As I said, I danced with my boyfriend at the WL Ballroom." "But last time you didn't give us your boyfriend's information, please ask for his name."

"Akiko." "I want the full name." Liang Xiaoyu waved his hand impatiently, "I just met that day, who knows what his name is." "Then do you have his contact number?" "No." Yu Zheng and Liu Gang glanced at each other, then changed the subject: "Tell me how you found your brother-in-law's body." "I've already said it." "Could you please say it again?" Although Yu Zheng was smiling, his voice was deep and intimidating. Liang Xiaoyu curled her lips, and finally repeated honestly: "I didn't go back until almost noon that day. I thought there was no one at home, but I saw their bedroom door was open, so I took a look inside and found that my brother-in-law was lying on the bed. On the bed, I went over to find out that something happened to him."

"In what position is he lying on the bed?" "It's face up." "Is he all in bed?" "No, he had one leg over the edge of the bed." "Which leg?" "Left leg, not right leg, I can't remember it just by looking at it." Liang Xiaoyu became impatient again. Seeing this, Yu Zheng changed the subject again: "As far as you know, is there anything wrong with your brother-in-law recently, or has any enemies, etc." "There's nothing wrong with him, but when it comes to enemies, there's only one." "Who."

"Liang Xiaoyun." The heavily dressed woman raised her head, staring straight at Yu Zheng with a pair of big empty eyes.
