Money can do a lot of things, but it can't do everything, we should know its field and limit it there, and even kick them back when it wants to develop further, all overly careful care about money sinks of greed.

Now, Xie Xintong and Xiang Shuifeng did not admit that they had killed Zhang Chengwang, so Xu Lang and the others had to start asking from the family of the deceased first to find a breakthrough.

According to the memories of the deceased Zhang Chengwang's parents, last night, after the banquet was dispersed, they first cleaned up the mess left by the wedding, because Zhang Chengwang was poured too much by the village during the day, and the banquet had not yet dispersed, so he was drunk and slept in the marriage room.

When everything was cleaned up, it was already more than one o'clock in the morning, the old couple went to the bedroom on the first floor to sleep first, and Xie Xintong went back to the marriage room on the third floor to sleep.

Zhang An They found that when their son Zhang Chengwang died, it was more than six o'clock in the morning, and they were startled by a scream from the bride Xie Xintong, at first, they thought that something had happened to the little couple upstairs, so Liu Zhongshu took the lead in going upstairs to check, and after pushing open the door of his son's bedroom, he saw Zhang Chengwang lying on the bed with a hideous face, Liu Zhongshu was stunned for a moment, and then walked over and stretched out his hand to touch his son's hand, and found that his hand was cold and cold, which scared Liu Zhongshu half to death, and then, Liu Zhongshu went crazy and shouted to Zhang An.

After Zhang An came up and saw this scene, he was also startled, and then, Zhang An called the village chief Zhang Bei and the village secretary Zhang Jing, and by the way, he also made a call to Ye Du, asking Ye Du to find Xu Lang and let Xu Lang come over to take a look, after all, Xu Lang is a policeman, although Xu Lang does not come back often, but the news of Xu Lang being a policeman has spread in Zhangjiatun a long time ago.

Zhang Bei and Zhang Jing rushed to the scene backwards, and the two of them touched Zhang Chengwang's pulse, and found that Zhang Chengwang's pulse had already stopped beating, and the corpse had already appeared corpse morture and corpse spots, so the three of them decided to call an ambulance and call the police as soon as they discussed.

At this time, Liu Zhongshu finally came back to her senses and was very emotional when she was sure that her son was dead, and she fainted on the spot, while Xie Xintong sat on the ground as if she had been greatly frightened, her body trembled, her face was pale, and she was crying.

At the beginning, Zhang An and the three of them did not suspect that Zhang Chengwang's death had something to do with Xie Xintong, after all, Zhang Chengwang was less than thirty years old, and he was in the prime of life, although Zhang Chengwang was a rural person, but he did the physical examination every year, and there was nothing wrong with his body, how could he say that he was dead, if Zhang Chengwang died of alcohol poisoning because of too much drinking, it was impossible, Zhang Chengwang was a very rational person, he usually drank very moderately, and rarely drank too much, but when the three of them saw Xie Xintong's performance, I was a little skeptical of my initial judgment, after all, there was no conclusive evidence to prove that Zhang Chengwang's death had anything to do with Xie Xintong.

Just after the three of them helped the fainted Liu Zhongshu to lie down on the sofa in the small living room outside, Ye Du took Xu Lang to the scene, Xu Lang first made a brief investigation of the scene, and did not express any opinions, and then Dou Xihua brought people to the scene.

After listening to Zhang An's story, Ning Yanran asked, "Didn't any outsiders stay at your house outside your family last night?" ”

Zhang An shook his head and said very firmly: "We are from the countryside here, and the people who came to attend the wedding were all neighbors from the village. ”

"That is to say, apart from the two of you, only your son Zhang Chengwang and new daughter-in-law Xie Xintong are at home?" Ning Yanran asked.

"Smack"

Unexpectedly, Ning Yanran had just mentioned Xie Xintong, Zhang An's face was gloomy, his mouth trembled, he slapped it on the table, and said hatefully: "That mourning star is not my daughter-in-law, I and Chengwang's mother didn't agree to this family affair at the beginning, it was Chengwang who wanted to marry that woman, and we had no choice but to agree, hey I knew it would be like this, at that time, whatever I said, I didn't agree with Chengwang marrying her." ”

Although Liu Zhongshu didn't say anything, she wiped her tears vigorously in the process of asking, obviously, she didn't expect that it was originally a happy event, but after a night, it would become a funeral, and it was a white-haired person sending a black-haired person, Liu Zhongshu's mood can be imagined.

This is the end of the inquiry, there are no outsiders present, there are only four of them in the family, Zhang An and his wife will definitely not kill their son, so it is difficult for anyone else to kill Zhang Chengwang except for the new daughter-in-law Xie Xintong, of course, this is only to determine the conclusion of the investigation, as for whether Xie Xintong is a murderer, further investigation is needed.

After the questioning ended, under the persuasion of Xu Lang, the village head Zhang Bei and the village secretary Zhang Jing, Zhang An and his wife returned home first, waiting for the results of the investigation, because it was already night after the inquiry, so Ning Yanran asked Zhao Hua to drive them back, Shu Yue originally planned to stay here, but was pulled aside by Xu Lang and said a few words, Shu Yue also followed back to Zhangjiatun.

Xie Xintong was temporarily detained because she was suspected of committing a major crime, and her mother Xiang Shuifeng was also temporarily detained, and the two were separated from each other in the detention center.

It was already late at night, but the lights in the Fangxi County Police Station were as bright as day, the police from the police station and the members of the second criminal investigation team brought by Ning Yanran were all in the conference room, and now, they were waiting for the news of Li Lei, who returned to the city with the evidence, and the results of Ye Xuefei's autopsy of the body.

At half past ten in the evening, Ye Xuefei, who had been busy in the dissection room for several hours, finally walked out of the dissection room and came to the conference room, and also brought the autopsy results.

The deceased Zhang Chengwang, male, 29 years old, 1.73 meters tall, weighing 145 pounds, after the autopsy, in the stomach of the deceased, the poison was found, the deceased died of poisoning, the toxicity of the poison is very strong, it is an acute poison, according to Ye Xuefei's preliminary judgment, it should be the poison - rat - strong because of the killing of rats, there is no food in the stomach of the deceased, and the deceased had drunk a lot of alcohol before death.

Xu Lang and they were not surprised by these conclusions, the only thing that surprised Xu Lang was that according to Ye Xuefei's autopsy, it was found that the deceased had been covered with something before his death, and there was a short suffocation process, in addition to the deceased's nails in addition to fibers such as bed sheets, Ye Xuefei also extracted a part of human tissue, according to the test results, it was found that it was not the deceased himself.

After having this major clue, Ning Yanran immediately asked people to collect and understand Xintong's biological samples, and compared them with the biological samples found in the fingernails of the deceased Zhang Chengwang.

The investigation of the case has reached this point, and it is very clear, and now the following points must be clarified.

First, the source of the poison that poisoned Zhang Chengwang was originally owned by Zhang An's family, or Xie Xintong's own.

Second, now everyone's spearhead is pointing at understanding Xintong, so what is her motive for killing Zhang Chengwang, only by figuring out this can she completely break through Xie Xintong's psychological defense.

Zhao Hua and Zhang Lei took the police from the Fangxi County Police Station to visit and investigate the residents of Zhangjiatun and Xie Jiagou Village, and figure out how Xie Xintong and Zhang Chengwang met, Ning Yanran and Xu Lang were responsible for interrogating Xie Xintong, and Ye Xuefei was responsible for comparing Xie Xintong's biological samples.

After the task was issued, it was already late at night, and everyone left the police station, and Ning Yanran and they lived in the guest house arranged by Dou Xihua.

Nothing was said one night, the next day.

Before six o'clock in the morning, Xu Lang finished washing up, woke up Ning Yanran and a few people, and a group of people came to the police station after a simple breakfast outside.

At ten o'clock in the morning, Li Lei rushed to Fangxi County from the city, and he brought back a very important evidence, the medicine bottle found in the closet, the white powder in the medicine bottle, through the laboratory test of the technical department, was determined to be tetramethylene disulfoxidetetraammonia, which is often called poison-rat-strong, and through the test comparison of the milk in the cup at the scene, the poison-rat-strong component was also found at the bottom of the cup, which belongs to the same chemical substance.

In addition, fingerprints were collected on the medicine bottle and the cup containing the milk, only one person's fingerprints were found on the medicine bottle, and two people's fingerprints were found on the milk cup, one of the fingerprints was the deceased Zhang Chengwang, and the other fingerprint was Xie Xintong's fingerprints, after having these two evidences, Ning Yanran and Xu Lang interrogated Xintong again.

When Xu Lang and the others began to interrogate why Xie Xintong killed Zhang Chengwang, Xie Xintong denied it in every possible way at first, defending herself, claiming that Zhang Chengwang's death had nothing to do with her, but when Xu Lang and the others took out two evidence bags, as well as the identification results of the medicine bottle and milk, and the results of fingerprint comparison, Xie Xintong was silent for a long time, and finally admitted that she killed Zhang Chengwang with her own hands.

The day before yesterday was the day of their wedding, and it was also the day when Xie Xintong married into Zhang Chengwang's house, Zhang Chengwang drank too much at the banquet during the day, and fell asleep, and after the guests were gone, she returned to the bedroom, at this time, Zhang Chengwang drank too much because of drinking, and after sleeping for a few hours, he woke up, and people who drank a lot of alcohol know that the reason why people get drunk is because there is a lot of alcohol in the wine, and after the alcohol enters the stomach, it is absorbed by the stomach wall into the blood, neutralizing the oxygen in the blood, resulting in insufficient blood supply to the brain. As a result, the brain is disturbed, and people wake up after being drunk, feeling dry and wanting to drink water.

Xie Xintong poured a glass of milk after Zhang Chengwang woke up, when she poured the milk, she put the poison prepared in advance into the milk, stirred evenly, and handed it to Zhang Chengwang, Zhang Chengwang felt that the taste was strange when he drank the first sip, and asked how the milk tasted weird, whether it was expired, but Xie Xintong told Zhang Chengwang that he had drunk too much and the taste had not yet recovered.

After drinking, Zhang Chengwang felt sleepy again, and fell asleep deeply, after more than ten minutes, Zhang Chengwang suddenly woke up, he first began to vomit violently, and then began to vomit blood, Zhang Chengwang didn't eat at all during the day, there was nothing in his stomach, and soon, Zhang Chengwang's seven orifices began to bleed, Zhang Chengwang felt very frightened, and wanted to wake up Xie Xintong, who was sleeping on the side, and when he turned around, he accidentally saw the milk cup on the bedside table, Zhang Chengwang immediately understood what was going on, so, Zhang Chengwang was like opening his mouth to call his parents downstairs, and Xie Xintong, who was not asleep at all, saw Zhang Chengwang like this, and immediately picked up a pillow and covered Zhang Chengwang's face, so that he couldn't shout loudly, during this period, Zhang Chengwang's hand scratched Xintong's body, but did not catch Xie Xintong's face and neck, but the position of the back shoulder.

In this way, under the reaction of the poison and suffocation, Zhang Chengwang soon died tragically on the bed, and after Xie Xintong did all this, he also put down the pillow, sat on the bed, looked at Zhang Chengwang with wide eyes and dead eyes, and after watching for a while, Xie Xintong got up and went to the bathroom to take a bath, and when she was taking a bath, she found that there was a wound on the back shoulder, so she changed into a bootie top and put down her coiled hair to cover the wound.

After doing all this, Xie Xintong hid the bottle containing poison in the small compartment above the closet, and then she waited until dawn in the morning, at this time, people were almost awake, so Xie Xintong let out a scream, attracting Zhang Chengwang's parents, and she pretended to wake up, originally she planned to send Zhang Chengwang to the hospital, but at this time, Zhang Chengwang had already died.

After listening to Xie Xintong's story, Ning Yanran stood up, walked to Xie Xintong's back, lifted her loose hair, pulled down her short sleeves, and indeed found a few scratches on Xie Xintong's back shoulder.

Although Xie Xintong confessed her criminal process, Xu Lang and the others still didn't understand why Xie Xintong killed her newly married husband Zhang Chengwang and what her motive was.

"Why did you kill Zhang Chengwang?" Xu Lang asked

"For the money." Xie Xintong lowered his head and said.

"What money? Zhang Chengwang's savings? Xu Lang asked again.

Xie Xintong shook his head, raised his head and glanced at Xu Lang, then at Ning Yanran, and then said, "No, it's for the bride price." ”

"Bride price?" Xu Lang and Ning Yanran looked at Xie Xintong in confusion.

Xie Xintong nodded and said, "Yes, it's just for the bride price." ”

Hearing Xie Xintong say this, Xu Lang suddenly remembered what Ye Du had said to him before, so Xu Lang asked: "Before you married Zhang Chengwang, you were married three times, and they all died shortly after the marriage, did you also kill them?" ”

As soon as Xu Lang said this, not only Xie Xintong raised his head and looked at Xu Lang with a shocked face, but Ning Yanran also looked at Xu Lang with a stunned face, if it wasn't for Xu Lang to say, Ning Yanran wouldn't know about it.

Xie Xintong looked at Xu Lang for a few seconds, then lowered his head again, nodded heavily, and said slowly, "Yes." ”

"Huh?"

Hearing Xie Xintong admit that she had killed her previous husbands, Ning Yanran exclaimed in shock.

Xu Lang turned his head and glared at Ning Yanran, Ning Yanran knew that she was out of shape, and hurriedly lowered her head and took a pen to record, Xu Lang turned his head, looked at Xie Xintong, and asked, "Then you can talk about it carefully." ”

In the next few hours, Xie Xintong was always telling alone, Ning Yanran was in charge of recording, and Xu Lang was looking at Xie Xintong expressionlessly.

Xie Xintong was born in a single-parent family, when she was very young, her father went out to work, at first, and sent money back to the family, but a few years later, that is, when Xie Xintong was six or seven years old, her father lost contact with the family, and since then, the two of them have never received a penny.

Xie Xintong's mother is also a woman with a bit of beauty, otherwise she would not have given birth to such a beautiful daughter as Xie Xintong, in the countryside, a woman with a child of a few years old, what if there is no financial resources, Xiang Shuifeng can only rely on farm work, planting crops to make a living, when the farm is busy, help other people's families do work, earn a meager salary, at the beginning, Xiang Shuifeng didn't feel anything, it was nothing more than a hard life, tired, but at least he could go on, but after a long time, watching other people's families live a good life, Xiang Shuifeng's heart was inevitably unbalanced, so he thought about how to make money, at this time, Xie Xintong just failed in the college entrance examination and returned home.

Xie Xintong's primary and junior high school were in Fangxi County, and most of the classmates in their class at that time were from the surrounding countryside, Xie Xintong didn't feel worse than others at first, it was nothing more than one less father than others, but after Xie Xintong went to high school in the city, everything changed.

When Xie Xintong went to high school, he was fifteen years old, it was puberty, compared to boys, girls generally developed earlier, and their psychology was more precocious, when they were in high school, Xie Xintong lived on campus, looking at the roommates in the same dormitory wearing brand new clothes, cosmetics, and endless pocket money, Xie Xintong was very envious, at this time, Xie Xintong began to resent herself, and not long after she was born, she abandoned her and her mother's father.

Xie Xintong was resentful at the same time, but at the same time, she learned to compare and love vanity, so she frequently asked for money from her family, but Xiang Shuifeng was just a rural woman, how could she have so much money, but her daughter was studying in school and needed money, and she couldn't help but give it to her mother, so Xiang Shuifeng began to borrow money from the village, and the rural people were more kind and simple, and they were still not sympathetic to Xiang Shuifeng's family.

However, in the three years of high school, Xie Xintong asked for money more and more times, and Xiang Shuifeng could no longer borrow money in the village, Xie Xintong was very dissatisfied, and every time he came back from the weekend vacation, he would quarrel with Xiang Shuifeng, and the relationship between the mother and daughter became increasingly tense.
