"There may be another reason, that is, Xue Kui is used to being domineering, and he is too unscrupulous. But in the process of implementation, he encountered an accident, and this accident was a godsend for Xue Kui. He was supposed to need to sneak up on Wang Mazi, and maybe set himself on fire, but when he arrived at the mine, he was surprised to find that Wang Mazi had fainted there, and the terrible butterfly elf flapped his wings and left. Xue Kui has been in the coal mine for many years, so he naturally knows the legend of the ghost-faced butterfly, so he wrote it down, planning to push the boat down the river and push the matter into the underworld. At the scene, Xue Kui picked up the fallen stone on the ground and smashed it with the skull of the would-be Wang Mazi, because it had to be an accident, so he only had such a chance, even if he couldn't kill Wang Mazi, at least he had to smash his head into a problem, and he couldn't speak again. ”

With this experience, Xue Kui was inspired to learn about Cao Bao's physical condition through other means before murdering him. Subsequently, let Liu Skirt approach Cao Bao in the name of Qin Xuechuan and lure him into the mine, these processes can be proved by the call records and Liu Skirt's testimony. After Xue Kui was sure that he was also bitten by a butterfly, he asked Liu Skirt to urge Cao Bao to report it, and Liu Skirt had dinner with him there, and according to Xue Kui's instructions, he drunk Cao Bao, which caused Cao Bao to die of alcohol allergy and heart disease. In addition, I have asked the police in TY City to investigate the meeting place that Liu Huan said, and the surveillance of the hotel there also corroborates this. ”

Xu Jie understood, "President Li, Xue Kui originally just wanted to kill people, but he inadvertently let the legend of the butterfly elf intervene in it, making things seem very bizarre and difficult to investigate. But what about Gao Kehua? If he was also killed by Xue Kui, this place seems to be wrong, because when Gao Kehua died, he went outside by himself, and before he left home, he didn't contact others, how did Xue Kui know that Gao Kehua would go out in the middle of the night?"

Li Yiting poured a glass of water again, drank it all, and his throat was really smoking, "Old Xu, what you said is very right, of course Xue Kui doesn't know." Therefore, he only has these two murders in his hands, and Gao Kehua was not directly killed by him. ”

"Then who else?" Xu Jie looked dazed, but within a few seconds, he immediately reacted, "I know, it's Tao Jinrong!"

"Haha, Captain Xu is really worthy of his reputation!" Li Yiting took the opportunity to praise, "Our Beiting didn't reveal too much information to you during the investigation, so it's difficult for you, I hope you don't care!

"Oh, don't praise me like that, I'm embarrassed, if our police can solve the case as soon as possible, we don't need you to spend so much money. Xu Jie was indeed more guilty, but the clarity of the case made him feel a lot better, and according to Li Yiting's analysis of the situation and the evidence obtained, he accurately deduced Tao Jinrong's problem.

Chen Tianyu listened to it for a long time, and couldn't help but speak, "Yiting also said that he was tired, Gao Kehua's case, I will explain." In fact, Xue Kui has always been uneasy about Gao Kehua, because Gao Kehua worked with Mei Yuanzheng in the coal mine after all, and fundamentally speaking, he is not his own person, so he has never regarded him as a confidant, but he just needs to use him. After our Beiting intervened, we quickly uncovered the cover-up incident, which caused Xue Kui to be very uneasy, first got rid of Wang Mazi, and lost one less insider. For his crimes, only Zou Qi and Gao Kehua are left in the mine to know better, and as I said just now, Zou Qi came in with Xue Kui, Xue Kui was more relieved, but he was very worried about Gao Kehua. Therefore, Xue Kui has been sending people to keep an eye on Gao Kehua in secret, and this person is Tao Jinrong. ”

Tao Jinrong was outside Gao Kehua's house, and found that he was in a hurry to go out in the middle of the night, and then followed, and gradually, he was sure that Gao Kehua was going to find Mei Yuanzheng. So as a last resort, he started and used an ether handkerchief stained with the ether that had been prepared long ago to stun Gao Kehua from behind. This handkerchief should be based on the characteristics of the Grimace Butterfly's situation, because at that time, Xue Kui had already figured out the secret of the Butterfly Elf, and he needed to continue to make the later cases related to the Grimace Butterfly, so he prepared the tools for Tao Jinrong to commit the crime. ”

Subsequently, Tao Jinrong called Xue Kui and asked how to deal with it, and the time shown in the phone record was more than three o'clock in the night. As everyone knows, the murderer took off most of Gao Kehua's clothes and shoes, causing him to freeze to death in the end. Of course, this approach is not safe, but in the city, there are cameras everywhere, Tao Jinrong did not dare to take Gao Kehua away, nor did he dare to use other methods, so he could only use this strategy, I believe this is also due to the suddenness of the incident, he saw Gao Kehua write a report letter, knowing that the matter was about to be revealed, and Gao Kehua must not be allowed to survive. After finishing the incident, Tao Jinrong hid on the other side of the alley to observe, and did not leave in a hurry until it was determined that Gao Kehua was found dead. ”

Xu Jie let out a long sigh of relief, such a complex reasoning is indeed not easy, "Detective, what you said is reasonable, and I just guessed that it was also inferred." But is there any evidence? Why is it said that it must be Tao Jinrong who stalked and killed people?"

Chen Tianyu nodded, "Of course there is, we have the call records of Tao Jinrong and Xue Kui, including at the time of the crime." At the same time, the surveillance of the street behind the alley took pictures of Gao Kehua's past, and soon, Tao Jinrong's figure appeared. The reason why we didn't suspect it before was because even at night, it was not strange for someone to walk on the road, but when Tao Jinrong appeared in Qin Xuechuan's car accident, we focused on screening and found the clue. ”

So far, Li Yiting has only one thing to understand, that is, what do these cases have to do with Qin Xuechuan? Why did Tao Jinrong often keep an eye on him, and finally caused him to have a car accident?

"By the way, Deputy Director Qin won't also be involved in the case, right? Isn't Liu Skirt his wife?" asked Xu Jie worriedly.

"At present, Qin Xuechuan should have been wronged by us, and he doesn't know anything. Although Liu Skirt is his wife, everything is done behind Qin Xuechuan's back, and she also admits this. Li Yiting explained.

"So how to explain the car accident?" Xu Jie asked everyone's thoughts

The coal mine explosion case and the serial murder case have finally been solved, but these seem to be unrelated to the car accident that happened later, and now Qin Xuechuan is unconscious, it seems that if you want to know the truth, you have to ask the parties Xue Kui and Tao Jinrong.
