Serious Crime Unit 1

Chapter 1054 Serial Suicide (16)
The two of them had no choice but to find Gao Liangdong, the veteran detective of the criminal police team.He is 63 years old this year. He was hired back to the police force after retirement. He is now mainly responsible for collecting police work information, receiving visitors, and handling letters from the public.

He heard that they wanted to know Qin Yayan's situation, thought for a while and said: "I know Qin Yayan's situation. Her parents had a car accident when she was 16 years old, that is, in the summer of 1985, and the pickup truck driven by her father ran off the road. , fell to the bottom of a cliff of more than 100 meters. Her father died on the spot. Her mother was sent to the hospital for rescue. Because her kidneys ruptured, she could not be rescued. She died on the third day, leaving her with a sister Qin Xiaoyan who was 8 years younger than her. .”

"Oh, so her fate is so tragic. Then how did she grow up and get admitted to college?" Zhou Ting asked.

"She and Qin Xiaoyan grew up under the care of her uncle. Qin Yayan is a very hard-working child. Except for sleeping, she spends all her time reading and never watching TV. God paid off. She was finally admitted to the provincial medical school, and She was admitted with the No. 1 score in the district. However, Qin Xiaoyan was not as hardworking as she was. After graduating from high school, she went to work."

"Why haven't we heard that she has a sister named Qin Xiaoyan?"

"Well, it's a long story. I don't even know where to start... I met Qin Yayan when she came to the branch to report a crime. I remember it was early July 1996. She came to the police to report that Qin Xiaoyan had been raped to death. , the body was still lying in the rental house in Qianyang Village. I had just become a criminal police officer at the time. After hearing this, I quickly reported it to Captain Chi Hua. Captain Chi immediately took people to investigate the scene, and I also went.

"At that time, Qin Xiaoyan was lying on the bed in the bedroom wearing pajamas and pajamas. Judging from the body spots and rigor mortis, she had been dead for 8 to 10 hours. There were no resistance wounds on the body, and there were no signs of struggle at the scene. The bedroom door was open, but The double door entering the living room was closed, and there was no sign of damage. If someone entered the bedroom and raped Qin Xiaoyan, the pajamas would have been torn and there would have been resistance wounds on the body.

"I don't know why Qin Yayan thought Qin Xiaoyan was raped to death. Later we asked Qin Yayan this question, and she said that she found several condoms with semen in the trash can in the bedroom. We all wanted to laugh when we heard it: There are still people wearing condoms. Raped the deceased multiple times? This is not very logical. Of course, we did not do it perfunctorily and performed an autopsy on the body.

"The autopsy results proved that Qin Xiaoyan did have sex with someone before her death, and it was crazy, because Qin Xiaoyan's vaginal wall was red and swollen. This was not caused by inflammation, but by multiple violent sexual intercourses. Qin Xiaoyan died of sudden cardiac death, It was not strangled or covered to death, nor was it raped to death.

"We extracted the semen from the condoms. However, at that time, DNA testing technology had not been used in grassroots criminal investigations, nor had a database been established. Therefore, we did not know who had sex with Qin Xiaoyan. We visited and investigated hundreds of people, but , there was no progress at all, and it was not until four months later that a new homicide occurred, and we temporarily put the case aside.

"However, Qin Yayan refused to give up and came to our criminal police team every three days to inquire about the progress of the case. Team Chi patiently explained to her that this was not necessarily a murder case. It was possible that Qin Xiaoyan was overly excited, leading to her death from mental and physical exhaustion. This kind of Qin Yayan was so disappointed by her statement that she went so far as to complain to the secretary of the district political and legal committee, accusing the criminal police team of perverting her.

"Later, when Qin Yayan came to inquire about the progress of the case, Captain Chi quarreled with her and kicked her out. Our Captain Chi has a bad temper, and you should know something about it. Maybe Qin Yayan was too disappointed with us, and she never came again. Go through the criminal police team to inquire about the case...that's probably the whole process. If you want to ask anything else, I'll tell you everything."

"Lao Gao, based on your years of experience in handling cases, do you think this is a murder case?" Zhou Ting asked.

"I don't think so. Qin Xiaoyan must have overplayed with her boyfriend and died of mental and physical exhaustion. And his boyfriend was afraid of being responsible and ran away secretly. Alas, if we find out who her boyfriend is, the most we can do is to detain him for education. , it is unlikely to be sentenced, why should Qin Yayan be so persistent?"

"I understand. Thank you for telling us so much. Let's go. Come to the city bureau to visit me when you have time. I'll treat you to dinner." Zhou Ting shook hands with him and said goodbye.When it comes to inviting colleagues to dinner, he definitely doesn’t say anything polite, but he sticks to his word!

"We have gained a lot from this trip. I didn't expect Qin Yayan's life experience to be so tragic. What do you think of Qin Xiaoyan's death?" Zhou Ting asked Xiaoke while sitting in the passenger seat.

"It seems that Qin Xiaoyan's death is not simple. It may be a clever murder, or the person who had a relationship with Qin Xiaoyan was malicious... Why do you say that? This is what I think: Qin Xiaoyan may have a heart disease, this person There may be a fatal clue in her hands, and she threatens him with this. Of course he wants to kill Qin Xiaoyan, but he needs a foolproof murder trick, so he can only use a delaying tactic and continue to have sex with Qin Xiaoyan in the name of falling in love. He dated her and agreed to marry her. Later, he learned that Qin Xiaoyan had a heart disease, and after making Qin Xiaoyan drink stimulants, he had sex with her many times, causing Qin Xiaoyan's sudden cardiac death. Even if he was found out, he could be said to be unaware. , the judge won’t even sentence him.”

"If that's the case, this person's criminal IQ is very high. I think the murderer may be a married big shot. Qin Xiaoyan wants to force him to divorce and then marry her. There are too many such cases. Many women are always greedy, so that It would lead to death. But why didn't Qin Yayan know who Qin Xiaoyan was in love with at the time?" "Qin Yayan is very career-minded. In order to make progress, she may have devoted all her energy to her career and had no time to care about Qin Xiaoyan. Lao Gao said, The Qin sisters originally lived in a bungalow in their hometown in Antou Village. After Qin Yayan entered the reproductive department of the Provincial Hospital, she moved to a doctor's apartment, while Qin Xiaoyan still lived in Antou Village, and later moved to Qianyang for some unknown reason. I think she might have rented a house there for the convenience of her work. The houses in Qianyang Village were very good at that time, and many white-collar workers lived there."

"It's a pity that there were no surveillance cameras installed around Qianyang Village at that time. If it were now, we should be able to find the murderer." Zhou Ting said, looking at the hurried passers-by on the road.

"I think Qin Yayan may have found the murderer later. However, she was very disappointed with the criminal police who handled the case, so she did not report it to the police. Instead, she determined to use her own way to retaliate against the murderer and make him pay with blood."

"There is another possibility: this murderer is too powerful. He may be a powerful figure who can control the entire Jiangxi District Bureau and even make the director obey his words. Qin Yayan knows that she cannot defeat him, so she can only outwit him, not investigate clearly. So, she wants to take revenge on him in her own way."

"Who do you think the murderer will be?"

"It should be sincere. Of course, this is just a speculation. There is no evidence to prove this." Xiao Ke received a WeChat message on his mobile phone. He did not read it, but concentrated on driving.

"Well, it's very possible that after Qin Yayan knew that the murderer was Zhenli, she tried to find a way to contact Zhenli and Yang Fei and became good friends, and then led Zhenli and Yang Fei into a trap step by step."

"But... there is one thing I don't understand. If the murderer is Zhenli, doesn't he know that Qin Yayan is Qin Xiaoyan's sister? Since he knows that they are sisters, how could Zhenli not be wary of Qin Yayan? And how did Qin Yayan set a trap? "Xiao Ke was a little confused.

"He must not know that Qin Xiaoyan is Qin Yayan's sister. Otherwise, based on his criminal IQ, he will definitely not have contact with Qin Yayan. I have a theory: Qin Yayan found several condoms in the trash can in Qin Xiaoyan's bedroom, and she immediately realized Qin Xiaoyan was killed because she knew very well that Qin Xiaoyan had a heart disease and must not indulge in sexual pleasure, and as Qin Xiaoyan's boyfriend, she must have known this, so Qin Yayan thought it was a murder."

"Qin Yayan was worried that the murderer had strong social power and maybe the police would be manipulated by him, so she froze the semen in the condom, which a reproductive doctor could do. And her reproductive department had This kind of equipment. It wasn't until she found out that Zhencheng was the murderer and learned deeply about Yang Fei's infertility that she spent a lot of money to find Qu Yihua and implanted Zhencheng's sperm into her body. After Qu Yihua gave birth to a child, She then called Zhenlei and asked the couple to adopt him. It wasn’t until a week before Zhenli’s death, or earlier, that she told Zhenlei the truth, and then instigated Zhenlei to force Zhenli to die. This was her conspiracy.”

"If that's the case, Qin Yayan is too smart. I can't imagine that she can calmly behave in such a wise way at such a sad moment. However, all of this is speculation. It remains to be seen whether frozen sperm is reliable. The team asked Luo Jin."

After they returned to the team, Zhou Ting went to ask Luo Jin.

"The survival time of sperm outside the body depends on the temperature and humidity of the environment. If the temperature is between 30 degrees Celsius and 37 degrees Celsius, it can survive for 3 to 8 hours. If it is frozen with liquid nitrogen, it can be stored for a long time. Zhou Ting, you ask this What for? Do you want to freeze sperm?" Luo Jin said jokingly.

"Where are you thinking? This is required by the case. My sperm has a shelf life of at least 40 years. Do you know General Yang Sen of the National People's Congress? He can still have children at the age of 91."

"Yang Sen is a scumbag, not worth mentioning... Tell me about the case." As soon as Luo Jin heard about the case, he immediately became energetic.So Zhou Ting told him the investigation and speculations he and Xiao Ke had made.
