Zheng Wanjiang expressed his inferences about the case.

The murderer and Li Qiulan knew each other, he climbed into the room from the courtyard wall, the time was after twelve o'clock, from the person is at least 1.8 meters tall, burly, familiar with the situation of Li Qiulan's house, or has been to her house before, after entering the house, Li Qiulan has not fallen asleep at this time, so the table lamp is not turned off, maybe because of He Jinqiang's death, she was in an extremely bad mood, did not pay attention to what happened outside, and did not expect that someone would enter her house and put her to death.

After the man entered the house, he used the drug that was rumored in the society, after Li Qiulan was drugged, her brain lost her sense of domination, and she was numb to be at the mercy of others, and under the instruction of the visitor, she wrote the suicide note, and asked Li Qiulan to put the cash in the desk, mainly to leave her fingerprints, trying to direct our attention to the direction of seeking money and killing people, and the 108,000 yuan in cash was by no means He Jinqiang's deposit.

Because Li Qiulan was the only one in the family, this gave the perpetrator a certain amount of time, he saw that he had bad intentions, and gave Li Qiulan an aphrodisiac, and had sex with her, when Li Qiulan's brain was unconscious, completely uncontrolled by herself, plus she took an aphrodisiac, delirious, so there was no sign of resistance and struggle, and she did not find **** in her body, indicating that he was afraid of exposing himself and took measures, this is a veteran of crime, after playing with Li Qiulan, the drug has not expired, and then hung her on a tree, caused Li Qiulan's death.

This gives the illusion of hanging himself, and since it is the dead of night, he has time to clean up the traces of the scene, and then he quietly leaves. He thought that what he did was not leaky, and he could hide it from the world, but Li Qiulan committed suicide in fear of sin. But he still left traces of the crime, one is that when he was tying the rope buckle, he accidentally touched the wire on the tree, leaving blood stains on the trunk and the rope used for hanging. The second is the height of the tether buckle, according to the height of the rope buckle, it is impossible for a woman who is a little more than one meter six to tie the rope buckle at such a high height. The third is saliva, after he had a relationship with Li Qiulan, probably due to excessive excitement, he casually spit a mouthful of saliva on the wall. Fourth, when he climbed over the wall into the yard, he left footprints on the wall and underground, which he ignored, thus leaving relevant clues for solving the case.

"Who do you think this person should be?" Chu Mingxiang asked.

"Judging from his height, personality and modus operandi, he has some strategies and means, it should be a person who killed He Jinqiang, this person knows He Jingang, and he will know some information." Zheng Wanjiang said.

"Then Zhu Chunhong must know him?" Chu Mingxiang said.

"I think so too, but we can't alarm her yet, he must be secretly paying attention to our actions, especially observing Zhu Chunhong's movements, as soon as we make a move, he will also take action, He Jingang's disappearance is an example, once he finds out, he will make a big move, which will make us unguardable. This is a gang crime, in addition to him, there must be other people, at present, Wang Wentong, Zhu Shibin and others have been revealed, these are all involved in each other, but we do not have conclusive evidence, it is difficult to decide the case for a while, we must find a way to find conclusive evidence, and wipe them out. Zheng Wanjiang said.

"From the current indications, Li Qiulan's death was premeditated, and it is nothing more than an attempt to lead us to Li Qiulan, to prove that Li Qiulan is a murderer or an accomplice, with the intention of seeking money and killing people, so that the case of He Jinqiang's death can be concluded as soon as possible. Now that He Jingang has disappeared or died, our clues have been interrupted, their plan can be said to be very thorough and rigorous, but they still fell into the trap, which provides us with a strong clue for the next step, you must follow the vine, obtain strong evidence, and completely destroy this criminal gang. Chu Mingxiang said.

"This is a major criminal gang, with a certain economic strength, and a large number of people that we can hardly imagine, so we can't act rashly, startle the snake, and not make them suspicious, especially him, he has been secretly observing our movements, and reporting to the outside at any time, which we have to guard against." Zheng Wanjiang said.

"Don't have too many concerns, there will definitely be difficulties, but he must be a paper tiger, with his fragile side, which can be broken as soon as he pokes, as long as there is conclusive evidence, I am not afraid that he will not be obedient." Chu Mingxiang said.

Huang Limei secretly met with Liu Shuhua in a hotel, took out the ring for him to identify, and asked her about the ring, Liu Shuhua looked at it and told Huang Limei that "Bai Ruifang" was the dead ** woman, the specific address was not clear, she thought about it and immediately called a girl, the girl was called Wang Huicui, she told Huang Limei that "Bai Ruifang" is her fellow villager, living in Sanhua County, Henan Province, is a poor mountainous area, six years ago came here to be a ** woman, Three years ago, she suddenly disappeared for unknown reasons, and she couldn't be contacted by any method, and her family searched for her many times, but to no avail.

Because Bai Ruifang is a ** woman, she has no status in society, and she is afraid of implicating other ** women after reporting the case, so she did not dare to report the case, and her disappearance has become a mystery in people's hearts, and after a long time, she will forget it, and no one will mention this matter again.

Huang Limei immediately reported the situation to Zheng Wanjiang, and Zheng Wanjiang immediately got in touch with the local public security department, and half an hour later, the local public security department faxed Bai Ruifang's relevant situation and photos, and after multiple verifications, it was determined that the deceased was Bai Ruifang.
