After a long journey of more than 6 hours, Yang Yu and Wang Ziwen finally arrived at Yang Yu's parents' home before 10 o'clock in the morning. The Yang family lives in a high-end villa area in Hoh. Yang Yu got out of the car and rang the doorbell, and after a while, the courtyard door opened, and Yang's mother and nanny and aunt also walked from the room to the yard.

"Mom!" Yang Yu took two quick steps and threw himself into his mother's arms, and the two of them hugged each other.

"Yu'er, you're finally back. After driving all night, I'm tired. Come inside and grab a bite to eat. ”

"Hello Mother Yang! Ziwen has come to see you again. As soon as Yang Yu and her mother hugged and separated, Wang Ziwen stepped forward and took Yang's mother's hand and said.

"Child, Xiaoyu, thanks to a friend like you, you have worked hard. Mother Yang said kindly.

A few people came to the house and sat down, and the nanny and aunt hurriedly went to the kitchen and brought up the breakfast prepared in advance.

"Xiaoyu, Ziwen, you drove all night, you must be hungry, eat something first. Mother Yang said with concern.

"Ziwen, let's grab the mat first. Yang Yu said to Wang Ziwen.

"Hmm. Wang Ziwen also felt a little hungry.

Yang Yu and Wang Ziwen had a simple meal, and then sat in the living room to talk to Yang's mother. Yang Yu sat beside his mother, holding his mother's right hand with both hands and said.

"Mom, don't worry, there's nothing that can't be passed, you tell me everything that happened. ”

"Actually, everything was normal yesterday, and your dad and I slept until a little after two o'clock, and then I was woken up by the nanny. Said there were police outside. Your dad and I asked the nanny to open the door for the police, and the police showed us a detention warrant saying that there was an explosion in your dad's coal mine, killing one and injuring the other. Your father, as a legal person, was summoned for detention in accordance with the law. Then the police took your dad away. After Yang Mu finished speaking, she shed tears.

"Mom, don't be sad, I'll do my best to deal with this. Since my dad came home yesterday, until now, has Ding Zicheng called you and my dad?

Ding Zicheng did not call. Others didn't call either. Mother Yang said.

The reason why Yang Yu asked his mother Ding Zicheng if he had ever called. It was Yang Yu who was wondering, why did he call him at two o'clock in the morning? Where did he get this information? Why didn't he tell his father about the mining accident in the first place? Why did he know that his father was taken away by the public security in the first place? The more Yang Yu thought about it, the more strange she felt, and she felt that there were many hidden secrets inside, and she wanted to solve these mysteries one by one. But the first time was to solve the matter of his father being taken away by the police.

After Yang Yu and Wang Ziwen finished eating, they immediately contacted the legal counsel of the mine and went to the public security bureau to visit their father together.

Yang Yu and legal counsel converged first. She didn't want her father to suffer, after all, he was not young. She wanted to take advantage of the loopholes in the judiciary reasonably. Yang Yu proposed the strategy of medical parole, and asked the lawyer how likely it was to implement it.

Yang Yu's father's company is called Daqingshan Mining Company, and the legal counsel is Qiu Shaoqi. Mr. Qiu believes that the method proposed by Yang Yu is very feasible and worth trying.

Yang Yu, Wang Ziwen, and lawyer Qiu went to the Public Security Bureau together and explained to Zhao Yijun, the deputy director of the Public Security Bureau in charge of the case, that Yang Chang was young and sick, and submitted a request for medical parole.

According to judicial provisions, the suspect was indeed allowed to be released on medical parole because of his physical illness. Deputy Director Zhao Yijun agreed to Yang Yu's request and allowed Yang Changqing to be physically tested at a designated forensic hospital.

Yang Yu, Wang Ziwen and lawyer Qiu accompanied Yang Changqing to the First People's Hospital of Hohhot for a physical examination. After Yang Yu, Wang Ziwen and lawyer Qiu arrived at the First People's Hospital, she, Wang Ziwen and lawyer Qiu took separate actions. Yang Yu alone found Han Jing, the deputy chief physician of the Department of Internal Medicine, in advance. Han Jing is a middle school classmate of Yang Yu's aunt Tan Xiaoyan. Yang Yu told Han Jing about the fact that his father might have been wronged. I hope Han Jing can cooperate and let his father Yang Changqing be released on medical parole.

Dr. Han Jing believed what Yang Yu said, and she promised to help Yang Yu's father, Yang Changqing, as much as possible without violating her principles.

The whole process of physical examination took more than two hours. After all, Yang Changqing is already nearly sixty years old, and he does have a lot of problems. Yang Changqing's blood sugar exceeded the standard, and there were lesion shadows in his lungs. The spatial scale on which the shadow of this lesion can be explained is relatively large. The diagnosis given by Dr. Han Jing is that the experiencer has a tumor and diabetes, and it is recommended to be released on medical parole.

After the final conclusion of the hospital's examination, Zhao Yijun, deputy director of the Public Security Bureau, agreed to sign the document for Yang Changqing's medical parole. That night, with the efforts of Yang Yu, Yang Changqing was released on medical parole and taken home. However, Yang Changqing's freedom was restricted, and he was not allowed to leave Hohhot until the investigation conclusion of the case was concluded, and he had to report to the police station in the jurisdiction every day.

That night, Yang Yu's family finally joined the group, and the nanny and aunt specially made a table of shocking banquets, and Wang Ziwen accompanied Yang Yu's family to understand the case while eating.

"Dad, didn't you receive a notice from the mine about the explosion in the mine?" Yang Yu asked as he sandwiched a piece of fish meat for his father.

"I haven't received any calls from anyone. It's really strange to say, according to the safety management system established by our company, if a mining accident occurs, there will be a safety department or the responsible unit for the mining accident to report directly to me. We also require that the mobile phones of the company's main leaders should not be turned off 24 hours a day. Yang Changqing held the rice bowl, looked at Yang Yu and said.

"Could it be that the person from the unit responsible for the mining accident is not on site, or that the person from the safety department is not on duty?" Yang Yu continued.

"If it were our normal production mine, this would not be the case. Because it is in a normal production mine, it is all working one team at a time. There is no possibility of a mining accident, they do not report it. There is only one case where a mining disaster is not reported. Yang Changqing thought and said.

"Dad, tell me quickly, this information is very important. Yang Yu also stopped eating, looked at his father and asked.

"That can only happen in abandoned mines that aren't producing. Only in abandoned mines that are not in production, accidents occur, and because there is no one, they cannot be reported. It was only during the temporary inspection that the accident was discovered. Yang Changqing said.

"I've heard that the mine that happened this time is an infrequently mined mine. Yang Yu said.

"Since it is a mine that is not in production, why would anyone go? Why would a mining disaster occur?" Yang Changqing was very puzzled.

"Could it be that someone did it on purpose? deliberately causing a mining disaster, and then putting the blame on you. Yang Yu said.

"I can't rule out this possibility, but what is the motive?

"I think the secret in this may have to be investigated to find out. The most fortunate thing now is that my father doesn't have to stay in the detention center. Now that you're at home, I'm relieved that I'll have time to fully investigate the matter. Yang Yu also comforted his father.

"That's it, you can stay at home and leave the rest to the children. Yang's mother also comforted Yang Changqing and said.

The next day, Yang Yu took Wang Ziwen to drive to Daqingshan Mining Company. They first went to the security office to learn about the situation of the victims of the mining accident. The security office is located in several offices on the left side of the first floor of the mine administration building.

Director Zhou of the Security Department is an old man of Daqingshan Mining Company, and Director Zhou naturally knows Yang Yu.

"Director Zhou, please give me a brief introduction to the situation of this mining disaster and the situation of the dead and injured in the mining disaster. Yang Yu got straight to the point.

"Okay Miss Yang. The time of the mining accident was around two o'clock in the morning yesterday. It happened in an old mine cave in our mine that had stopped mining. This cave is numbered Cave 1012. It was a security bombing. Fortunately, the explosion area of the mine was not very large, and it did not cause the entire collapse of the mine. But the explosion left one dead and one injured. The deceased is called Ding Shicheng, and the injured is called Qiao Xisan. Ding Shicheng's body has been taken away by the Public Security Bureau for forensic examination. Qiao Xisan was seriously injured, and he is still being rescued in the ICU emergency room of our mining area, and he is not out of danger of life. Director Zhou said.

"How did our security department know about the mining accident when it happened?" asked Yang Yu.

"When the mine accident happened, the security department didn't know about it at first, because it was a mine that had stopped mining, which meant that there was no one there. In addition, it was late at night when the explosion occurred, and the area of the explosion was not large, and the movement was not large, so it was not easy to detect on the ground. After the explosion, I received a call from General Manager Ding Zicheng at about 2:30 a.m. yesterday, and it was he who told me that there had been an explosion. After I received a call from Mr. Ding, I rushed back to the mine from home overnight. On the way here, I called Qi Yuan, the officer on duty at the security office. It was Qi Yuan who rushed to the scene with other personnel and notified the medical staff of the hospital in the mining area to start the treatment work. ”

"Director Zhou, what are these Ding Shicheng and Qiao Xisan doing in the mine? Why did they go to the mine cave where mining stopped in the middle of the night?" Yang Yu asked.

"Ding Shicheng and Qiao Xisan are from the coal washing plant. Ding Shicheng should be Ding Zicheng's younger brother. As for why they went to Cave 1012, we don't know. The person concerned, Ding Shicheng, has died, and Qiao Xisan is also in the ICU emergency room, and he can't speak yet. Therefore, why did they go to the 1012 mine, we still need to wait for Qiao Xisan to speak, and then do further investigation. Director Zhou explained to Yang Yu.

"Director Zhou, can you arrange for someone to take me to the scene of the explosion to have a look?" Yang Yu wanted to take a look at the scene of the incident, and she wondered if she could find some clues.

"I'll take you there myself, I don't have anything else to do right now. ”

"Okay, then it's troublesome Director Zhou. ”

"Let's go. Director Zhou said as he took Yang Yu and the others outside.

Cave 1012 is the early mine of Daqingshan Mining Company. Mining stopped after more than eight years. It's been almost three years since mining was stopped. The location of the 1012 mine is about 10 kilometers away from the current administrative office building of the mining area.

Director Zhou took Yang Yu and the others and drove to the location of the 1012 mine in about ten minutes.
