Due to the successive death cases, all of which were related to coal mines, Chen Tianyu gathered everyone and returned to the guest house to discuss the case. This is already the fourth person who died among the people in this case after Beiting came to the local area, if it is not controlled, there may be more serious things happening, they can't accept more people, and they lose their lives for no reason.

Li Yiting first reviewed the previous two cases, "First of all, the team leader Wang Mazi saw a grimace butterfly in the mine, and then he went home to confess, about a week later, he died in the No. 2 mine, the cause of death was hit on the head by a stone in the mine; Although the two cases occurred far apart, the means and methods of committing the crime were almost the same, and there was also the possibility of accidents. However, as we all know, they were all involved in the coal mine explosion and the concealment of the death list, and the probability of accidental death in the same period is very small, and we must treat it as a murder. Now, these two cases have happened for more than half a month, is there any other progress in your investigation?"

Liu Zichen responded, "Jiudao and I met Wang Ruyun, the wife of the deceased Wang Mazi, and Yan Baoping, the mother of the deceased Cao Bao, during our visits to the periphery. Wang Mazi had a scuffle with Tao Sansheng, and caused the latter to be injured and expelled, while Cao Bao had an unpleasant encounter with Xue Kui because of the pension, so Tao Sansheng and Xue Kui had a motive. But after our investigation, we found that although Tao Sansheng had the motive and time to kill Wang Mazi, Cao Bao died in the second case, and Tao Sansheng stayed in the local area that day and did not go far away, which Mingyue can confirm. “

Shen Mingyue immediately opened her mouth to confirm, "Well, I'm also a human witness." Because I lived in Tao's house during this time, I don't know about the first case, but on the day Cao Bao died, I saw Tao Sansheng resting at home in the morning and afternoon, with an interval of three or four hours, which was not enough to go back and forth between the two places. ”

Li Yiting nodded, "In this way, Tao Sansheng's suspicion can be ruled out." If it was a murder case, Wang Mazi and Cao Bao must have died at the hands of the same murderer, and it is impossible for two different murderers to kill people by the same means without knowing it. Zichen said just now, and Xue Kui, does he have the conditions to commit a crime?"

Liu Zichen continued, "That's right, Xue Kui's whereabouts are very secretive, not easy to find out, and there are many people he has interacted with. So far, there is no evidence to show that when Wang Mazi and Cao Bao died, he had alibi evidence, of course, we also have no evidence of his presence, so we can only list the suspects. ”

"There is a suspect, it is better than nothing, at least Xue Kui is a murderer of coal resource resale, there is no doubt about this, his motive is very sufficient. I've told Yongkun to keep an eye on him to see if anything else is found. Chen Tianyu interjected.

After Li Yiting roughly sorted out the situation of the first two cases, he told Yan Baoping's case, "I think this matter is simpler, Yan Baoping was hit by a car on the road out of the city and died, or more precisely, it was the car she hit that caused the death." Unlike the previous two cases, Yan Baoping's body was not found to contain hallucinogens, and she had not been to the mine. Her case was probably an accident, but it is not certain, because the trigger for her mental problems was the kite, and it is indeed doubtful that the kite was dressed up in the image of a grimace butterfly. By the way, isn't the one who flies the kite the son of Qin Xuechuan, deputy director of the Mining Bureau?"

Kuang Suo finally had a chance to speak, he took out the prepared file and handed it over, "This is Qin Xuechuan's detailed information, this person is a graduate of a prestigious university, talented and intelligent, and his academic performance has always been among the best." After work, he was appreciated for his ability, and he was repeatedly promoted unusually, and he became the deputy director at the age of 33. ”

Li Yiting quickly finished reading Qin Xuechuan's introduction, although it was detailed, it didn't seem to be particularly useful, "Jiudao, these materials can only prove that Qin Xuechuan is an excellent talent, it doesn't seem to be helpful to the case, right?"

Kuang Suo was not in a hurry, and explained methodically, "That's right, I investigated the connections around him based on his academic history and work situation, and made two major discoveries. First, Qin Xuechuan and Xue Kui are good friends, the two have appeared in public many times, going in and out of some important places together, or participating in important meetings, in addition, according to insiders, they have also gathered in private, went out to eat, traveled, often carried out activities, and had an extremely close relationship. Second, Qin Xuechuan and Tao Sansheng's eldest daughter Tao E are junior high school classmates, according to my visit, they should still have a little abnormal relationship, but there is no evidence, so they can only be suspicious. ”

Chen Tianyu heard what he wanted to hear the most, Qin Xuechuan was really different, and he had a close relationship with Xue Kui, which was enough to show that he had the motive and ability to be involved in the transactions of Xue Kui and others, so many things could make sense. As for the relationship between Qin Xuechuan and Tao E, Chen Tianyu was not surprised, because a long time ago, when Fat Sheng was monitoring Tao Sansheng, he found that Qin Xuechuan and Tao E were going home together, and that day, Shen Mingyue was also in it, and he saw it with his own eyes.

In Chen Tianyu's mind, a complete context gradually became clear. In fact, these deaths themselves are not complicated, and the suspects have surfaced early, and the difficulty for Beiting is that there is no evidence to point to the murderer. And, most importantly, the original intention of their visit was to investigate the coal mine explosion, and there has not been much breakthrough in this matter.

Xu Jingnan rushed back, he brought back the autopsy report urgently needed for this case analysis meeting, in order to find out the truth of the facts, Xu Jingnan can be said to have gone all out, in the shortest possible time, once again completed the autopsy and laboratory examination of Gao Kehua's body.
