After lunch, Gu Song called Liu Yang and asked him if he was free to meet today and if he could talk about Yu Jianan's case.

Liu Yang happened to be resting today, and he was fishing at a farmhouse on the outskirts of the city. Hearing that Gu Song wanted to inquire about Yu Jianan, he immediately sent the address information to Gu Song's mobile phone, and told Gu Song that he could go over to find him at any time.

Dozens of minutes later, Gu Song and Xia Shi drove to a farmhouse called "Juxian Village". Before he got out of the car, Gu Song saw Liu Yang standing on the side of the road and waved at them, signaling them to park the car in the yard.

It turned out that this Juxian Village was opened by Liu Yang's parents, and Liu Yang occasionally came here to fish when he was free, and by the way, he helped his parents take care of the business, so as to relieve the pressure and fatigue of the criminal police.

The three of them sat down in a courtyard full of flowers and plants, and Liu Yang's mother made three cups of good tea for them. Although the outside temperature is as high as 34 degrees Celsius, and the scorching sun makes people drowsy, it is still very comfortable to sit under the shade of a tree and drink tea while blowing the wind.

On June 29, Liu Yang also attended Fan Cong's memorial service. He wanted to find an opportunity to chat with Gu Song, but he didn't see Gu Song at the memorial service. After all, he and Gu Song are not colleagues in the same bureau, their relationship is not close, and they don't know much about many things. After a few words of greeting, he asked Gu Song suspiciously, "What case have you been busy with lately?" The mystery was so mysterious that he didn't even go to his brother's memorial service. ”

Hearing this, Gu Song put the glass he had just picked up back on the wooden table, and his face suddenly became gloomy. He was reluctant to talk to anyone about Fan Cong's death, because it would evoke the grief and remorse that he had suppressed in his heart.

Liu Yang didn't understand the hidden secret, and felt that Gu Song's reaction was a little weird. At this time, he saw Xia Shi sitting next to him shaking his head lightly while glaring at him, signaling him not to inquire about these anymore, and quickly changed the topic: "Let's get down to business." Liu Yang, how is the investigation of Yu Jianan's case? ”

"There has been some progress, but the murderer hasn't been caught yet." Liu Yang spread his hands, revealing a helpless expression. "This case has been delayed for a long time, so I'd better briefly summarize the case with you first."

On April 12, 2016, Yu Jiannan "disappeared" from R City Normal University, in fact, because of lack of money, he privately contacted organ traffickers, and was "captive" as a donor in a cheap rental house at the North Railway Station.

On April 29, Yu Jiannan was successfully matched with a young female patient, and soon underwent kidney removal surgery at the Affiliated Hospital of R City University of Traditional Chinese Medicine under the arrangement of organ traffickers.

On May 3, Yu Jianan's sister Yu Jingyun discovered that her brother's whereabouts were unknown, suspected that he had fallen into a pyramid scheme again, and went to the police station to report the case for the third time.

On May 16, Yu Jiannan received a reward of 31,500 yuan from organ traffickers and left the rental house safely. After DNA comparison, the police confirmed that Yu Jianan's death had nothing to do with the organ trafficker.

On May 17, Yu Jiannan had a physical altercation with someone (the suspect), and his neck was strangled with both hands, resulting in mechanical suffocation, and his body was discarded naked in a small lake in the eastern suburbs of R City. (The suspect wanted to use the fact that Yu Jiannan had sold his organs to divert the attention of the police investigation and buy himself more time to escape the punishment of the law.) ）

On the morning of May 27, Mr. Ma, a citizen, found the body of an unknown male in the lake. The police extracted a little skin tissue from the nails of the corpse, and suspected that the suspect was scratched by Yu Jiannan when he committed the crime, leaving strong evidence for the police.

On May 29, the police confirmed the identity of the deceased as Yu Jianan, who had been "missing" for more than a month and a half, and began to file a case for investigation.

Since the police focused their work on tracking down the organ traffickers related to Yu Jiannan at the beginning of the investigation, they really delayed a lot of time, and only after all the suspicions of the gang members were ruled out did they shift their investigation to other aspects.

According to a boy named Chen Qing, the reason why Yu Jiannan came out to sell his kidney was because he was involved in gambling and owed tens of thousands of yuan in gambling debts to others.

Yu Jiannan has no father or mother, and he is still in college and has no financial income. He didn't dare to ask his sister for money to pay off his debts, because he knew that it was not easy for his sister to provide him with education. He often squandered the tuition and living expenses that his sister gave him, and his sister was so angry that he shed tears while scolding him. So this time, he didn't want to add another heavy burden to his sister.

Chen Qing is also a donor who was "captive" by organ traffickers, only 20 years old this year, because of family difficulties, he came out to sell his kidney, and lived in a rental house with Yu Jiannan at the North Railway Station. The two are of the same age, and they also like to play online games, and they will get together to chat in their spare time. Yu Jianan's participation in gambling seems to have been told to him alone.

According to this clue, the police searched all the large and small casinos in R City, interviewed hundreds of people, and combined with the information provided by Chen Qing, they finally figured out the causes and consequences of Yu Jianan's participation in gambling and selling his kidney to repay the money.

At the beginning of April, Yu Jiannan once took the living expenses (about 5,000 yuan) given to him by his sister to participate in crowd gambling in a small casino hidden in a residential building and a very hidden location, and owed nearly 40,000 yuan in gambling debts. The creditor seized his identity and student ID card, and made him have to pay it back within a week. With his three-inch tongue, he was able to get a one-month repayment deadline.

In order to repay the money, but also to avoid the trouble of creditors running to the school to find him. He thought about it and felt that selling his kidney was the fastest and most convenient way to make money. So, he contacted a black agent on the Internet, lived in a so-called "concentration camp", and got paid more than 30,000 yuan a month later.

On the evening of May 16, Yu Jiannan came to the hidden small casino again, wanting to use the 30,000 yuan in his hand as the principal and gamble with them again.

Gamblers have such a mentality, that is, after losing money, they want to win back all the money they lost, and after winning, they want to continue to win, using this means of not working hard to accumulate more wealth for themselves.

After selling her kidney, Yu Jiannan obviously felt that her physical fitness had deteriorated, and she would sweat at every turn, and she was afraid that she would not be able to do any tiring work in the future. This kind of psychology even more motivated him to try his luck and make a windfall. So, from the evening of the 16th to the morning of the 17th, Yu Jiannan stayed in that small casino, stayed up all night and fought, and unknowingly lost all the blood and tears money he had exchanged for his health for the rest of his life.
