Under the rigorous investigation of the expert team, the whole story gradually became clear.There is a well-planned conspiracy hidden behind the Xishan Mine case. The police have tried their best but still cannot reveal the true identity of the unknown body No. 11.It turned out that Chen Xiaoqiu had long announced that she was going to South Korea to work, and Song Xiaojun took her to the train station alone. During this period, she cut off all contact with her family.In fact, he was secretly preparing for the robbery of wages from the Xishan Coal Mine treasury.

After careful consideration, the expert team decided to arrest Song Xiaojun, Song Xiaomin and Sun Zhe.Cao Zhongshu quickly convened members of the task force to discuss an action plan.Wei Ning suggested taking action at three or four in the morning, while Han Jingdong believed that six-thirty in the morning was more appropriate, because it would be dark by then and the suspect might be in a more relaxed state, and at the same time it would not cause any disturbance to the public.Cao Zhongshu finally adopted Han Jingdong's suggestion.

According to the plan, Han Jingdong assigned Qin Chuan and Ye Maosheng to be responsible for the arrest of Song Xiaojun, Hu Bing was responsible for Sun Zhe, and Xiao Qingdong was responsible for Song Xiaomin.The police officers went to wait near the suspect's residence in the early morning.Just after six o'clock, the three arrest teams quickly attacked. Qin Chuan and Ye Maosheng captured the sleeping Song Xiaojun at Bai Ling's home, while Hu Bing and Xiao Qingdong also successfully captured Sun Zhe and Song Xiaomin respectively.However, no tools of crime were found during a search of their residence.

In the Pre-Trial Section of the Public Security Bureau, section chief Tan Mulin conducted strict interrogations on the three of them.Song Xiaojun responded calmly and insisted that he had nothing to do with the Xishan Mine case. He was at home on the day of the incident and provided alibi evidence and witnesses.He insisted that Chen Xiaoqiu had gone to South Korea and the two had no contact so far.At the same time, he also revealed the relationship between Chen Xiaoqiu's mother Su Xiuyun and Bai Ling, saying that Su Xiuyun regarded Bai Ling as her goddaughter.Xiao Qingdong conducted an in-depth cross-examination of Song Xiaojun, but Song Xiaojun always avoided his relationship with Chen Xiaoqiu and blamed all contacts on his wife Bai Ling.

Although the driver, Lao Luo, was asked to identify the three people, he was unable to do so because they were all masked at the time of the incident.Song Xiaomin claimed that he was playing mahjong with his friends on the day of the incident. After verification, the police confirmed that his statement was true.Sun Zhe, on the other hand, seemed extremely nervous. He claimed that he went out to work in November last year and provided evidence of alibi.After discussing with Wei Ning and Han Jingdong, Cao Zhongshu decided to release Song Xiaomin first and find a breakthrough from Sun Zhe's wife.However, investigators did not obtain valuable information when questioning Sun Zhe's wife. Neighbors confirmed that they saw Sun Zhe carrying a large bag home the day after the incident.The pre-inspector conducted a detailed cross-examination of the three people but found nothing unusual.Wei Ning believed that Song Xiaomin's suspicion could be eliminated and decided to interrogate Sun Zhe and Song Xiaojun again.

Facing Bai Ling who refused to cooperate, Qin Chuan took the initiative to ask Ying for interrogation and sent someone to pick up her child.Qin Chuan used the murder of Gao Jianshe as a breakthrough to persuade Bai Ling not to shield Song Xiaojun.When she heard the child's cry, Bai Ling's psychological defense finally collapsed.She recalled the scene in 1993 when Song Xiaojun took her to stay in a luxury hotel and gave her a big gold ring after he made a lot of money, but now she is more willing to stand up for justice.
