Chapter 74: No Light in the Sky 03 Use a Lie Detector
Chapter 3
"Who are you?" The kindergarten teacher looked at the young woman in front of her. She looked completely different from the Qin Yu mother in her memory.
Liao Qingya introduced herself: "I am Qin Yu's sister. My mother is in the hospital and can't come, so she asked me to come here."
The teacher nodded and said to Liao Qingya, "The little girl who was bullied was Qin Yu's deskmate. This is not the first time Qin Yu has bullied her."
The teacher took Liao Qingya to the office and saw the little girl who was beaten by Qin Yu.
Seeing Qin Yu's parents coming, the girl's parents immediately stood up and asked for an explanation.
"How do you educate your children? How can you hit others?"
Liao Qingya quickly apologized: "I'm sorry, we didn't educate our children well."
Liao Qingya pulled Qin Yu over and said, "Qin Yu, apologize to your classmates, apologize to your uncle and aunt."
Qin Yu curled his lips and refused. Liao Qingya pressed him down and apologized. She said to the girl's parents, "We will definitely educate our child well in the future. Sorry for causing you trouble."
"If we don't educate her well now, she will kill people in the future." The little girl's mother was furious. "Teacher, please change my daughter's seat. We don't want to sit with Qin Yu anymore."
"It will be readjusted, and something like this will never happen again." The teacher immediately assured.
Liao Qingya admitted her mistakes with a good attitude throughout the whole process. She also apologized while pressing Qin Yu. The girl was not injured, so her parents did not make it too difficult for Liao Qingya.
After the girl's parents left, Liao Qingya also left with Qin Yu.
In the car, she asked Qin Yu: "Why did you hit your classmate?"
"Because she is disobedient." Qin Yu said.
Liao Qingya didn't understand what he meant, "What do you mean?"
Qin Yu lowered his head: "Dad said that women who don't obey should be beaten."
·
"Impossible, I don't remember any of these things." Liao Qingya denied again and again, "If it was really me who did it, why don't I have any memory of it?"
"There is sufficient evidence. You were the only one who entered the crime scene during the time period of the incident." Lu Changfeng patted a stack of documents on the table.
"But I really didn't do what you said." Liao Qingya emotionally defended herself, "I really didn't do this. What do you want me to do so that you can believe that I really didn't do this."
No matter what Lu Changfeng said, Liao Qingya insisted that she was wronged. The interrogation could not continue, so Lu Changfeng had to end it first.
After returning to the monitoring room, Lu Changfeng asked Yue Fanglin: "What do you think?"
"Based on my many years of experience in handling cases, I don't think she lied." Yue Fanglin asked back, "What do you think?"
Lu Changfeng said: "I also think she is not lying."
“But if she really wasn’t lying, who was the person in the car?” Jing Jue said, “Maybe her acting is too good.”
The evidence shows that it is Liao Qingya, but her situation always makes people feel that something is wrong.
Lu Changfeng looked at Kuai Li: "What is Captain Kuai's opinion?"
"Based on my experience, it doesn't seem like Liao Qingya is lying."
Deputy Captain Zhang Pengyang suggested: "Why not find a psychologist and use a lie detector to test it."
"Polygraph test results cannot be used as evidence."
"Of course I know." Zhang Pengyang said: "Although the results of the polygraph cannot be used as evidence, at least the polygraph can be used as a reference to determine whether she is lying. Now we have evidence and surveillance footage in our hands. Even if she does not plead guilty, we can still convict her without a confession. Even if she is lying, it is no loss to us. But if she is not lying, we have to consider whether she has a mental illness."
Everyone nodded, thinking that what Zhang Pengyang said made sense.
Lu Changfeng thought of a case they handled that year. At that time, he had just met Qiu Shaoyang. The murderer in that case was a patient with multiple personality disorder. The other personalities killed people, but the main personality was not clear.
Liao Qingya grew up in an environment filled with domestic violence. Her mother is now sick in the hospital, and her stepfather refuses to pay for her medical expenses. It is reasonable to say that this awakened the dark side of her heart, causing her to have a split personality and kill Qin Ou.
"Okay, then I'll contact Professor Jian and ask her to come and give Liao Qingya a lie detector test."
At this time, someone pushed the door open.
Everyone looked over, and the detective said, "Qin Ou's son is here."
Lu Changfeng and Yue Fanglin looked at each other and walked out.
Qin Fei and his wife stood in the corridor.
Kuai Li hurriedly stepped forward to introduce himself: "Hello, I am the criminal police officer in charge of this case. My name is Kuai Li."
After that, he introduced Lu Changfeng and Yue Fanglin behind him, "These two are the overall persons in charge of the case, Captain Lu and Captain Yue."
Qin Fei and his wife looked at the two of them and simply nodded.
"Have you caught the murderer who killed my father?"
"We have a suspect." Kuai Li and Qin Fei said, "We have some questions we would like to ask you. Is it convenient for you now?"
"Is it related to my father's death?"
Kuai Li nodded.
"Then ask."
Kuai Li took them into the office and sat down face to face.
Kuai Li gave the right to question to Lu Changfeng.
Lu Changfeng did not refuse and went straight to the point, "Qin Fei, is there any hatred between your sister Liao Qingya and your father?"
Qin Fei was stunned for a moment, then he reacted and asked, "Did Liao Qingya kill my father?"
Lu Changfeng said: "The case is still under investigation."
Qin Fei took some time to accept it.
“There are indeed some things.”
Qin Fei recounted what happened between them: "Liao Qingya is the daughter of my stepmother and her ex-husband. I don't have a good impression of them. When Liao Qingya followed her mother into our home, I was fourteen years old. My mother had just passed away for more than a year. My relationship with my father was not good. I usually lived in school, and on Saturdays and weekends I mostly stayed with my grandparents. During long holidays, I would go to my grandparents' house."
"It should be the second year after they came to my house. One day I went home to get my things and saw my father attacking Liao Qingya."
Lu Changfeng: "When you say attack, do you mean your father violated Liao Qingya?"
"Yes, that should be the first time. He didn't know that I was at home and Cai Yun was at work. He thought it was just him and Liao Qingya at home."
"Liao Qingya resisted at the time, but my father threatened her that if she didn't obey, he would kick her out."
"Why didn't you stop it then?" Lu Changfeng asked him.
Qin Fei said: "I was only fifteen years old at the time. He beat and scolded me and my mother at every turn. He was not a good person. I didn't like Liao Qingya and her mother, so I simply pretended that I didn't know about it."
With this addition, Liao Qingya's murderous intent towards Qin Ou will be even stronger.
"What happened next? Did your father abuse Liao Qingya for a long time or was it just that one time?"
"As far as I know, it's long-term." Qin Fei said: "When I was about to graduate from high school, my family's financial situation began to deteriorate. My father couldn't get back the project funds he lent out, and couldn't pay wages. The company almost went bankrupt."
"He often took Liao Qingya out to eat, drink and discuss business. I didn't really care about family affairs. I had a house in my name, and my grandparents were pretty good to me. I seldom lived at home after my mom died. I didn't know much about their affairs, but I heard a little bit. I heard that my dad asked Liao Qingya to have dinner with his clients and seduce them into having sex with him, using this as a threat to exchange projects or business. Liao Qingya was still a minor at the time. Regardless of whether it was voluntary or not, anyone who had sex with her would be found out as long as they reported it to the police. Those people were afraid of this, so they could only suffer in silence."
"I went to the north to study at university, so I had less to do with family affairs. But I also learned from my grandparents that life at home was much better. Those were the most glorious years for my dad, who could earn several million yuan a year."
"During the Spring Festival of my junior year, Liao Qingya threatened to commit suicide at home and demanded that my dad give her $500,000, otherwise she would tell the police about what he had done. My dad was already having a hard time at that time, and several people who did business with him were found to have committed economic crimes. If Liao Qingya really sued him, he would be in big trouble, so he gave her the money at that time."
"Does Liao Qingya's mother know about this?" Lu Changfeng asked.
"Of course she knows." He said to Lu Changfeng and the others, "Cai Yun has very strange ideas. She didn't have a good life for a few years after marrying my dad. She was always beaten. If it were someone else, they would run away while they could, but she didn't. She must have known what my dad asked Liao Qingya to do. A mother can push her child into the fire pit. I think she is not worthy of being a mother at all."
"After I got married, I moved into my own house. It was transferred to my name when my mother was still alive. At that time, she and my father were getting divorced, and the family houses were transferred to my name. Over the years, I still know a little about family affairs. Liao Qingya almost stopped contacting the family after she went to college. Cai Yun gave birth to another son at that time, and Liao Qingya almost completely stopped contacting her. Without Liao Qingya's help, my father's business did not last for a few years and encountered a special trend, so it went bankrupt. In addition, he is old now, and the family still has some money for him to enjoy his old age."
"Do you know that your father often beats Cai Yun?" Lu Changfeng asked.
"I know. After all, when my mother was alive, he also beat me and my mother." Qin Fei really didn't have much affection for Qin Ou. "But if Cai Yun is willing to bear it, that's her own business. It has nothing to do with me. I have never considered her a family member. In my heart, I am an only child, and I don't have any brothers or sisters."
"So you didn't pay for her treatment this time when she was sick."
Qin Fei nodded: "I haven't received much care from her, nor have I made trouble for her. My father is not without money. It can't be blamed on me if she doesn't have money to treat her illness."
Everyone can see from Qin Fei's attitude that he has no feelings for Qin Ou, let alone for other people.
After Qin Fei left, the Criminal Investigation Team and the Serious Crime Squad held a meeting in the conference room to discuss the matter.
Everyone agreed that Liao Qingya had sufficient reasons to kill Qin Ou.
Lu Changfeng: "I plan to find her mother Cai Yun to find out what Qin Fei said."
"It's unlikely that Cai Yun will tell the truth." Kuai Li guessed.
"It doesn't matter if she doesn't tell the truth. At least we can understand her attitude towards her daughter being molested. If she is an accomplice, she can't escape."
Kuai Li: "Then I'll arrange for someone to take you there."
"good."
Lu Changfeng discussed with Yue Fanglin, and he took Jing Jue to the hospital to find Cai Yun to find out the situation. Yue Fanglin and Zhou Yu stayed in the bureau to investigate more information about Liao Qingya.
