Zheng Wanjiang carefully examined Li Qiulan's body and found no scars or bleeding, so who could be the bloodstains on the trunk, indicating that another person had come to the scene, and Li Guofu and his wife were the first to find the body, not they left it. Who could this person be, how did he get into the yard, Li Qiulan really hanged herself, that person watched Li Qiulan die, why didn't he rescue and report the case, there is something strange in this.

Zheng Wanjiang looked at the back door, there was no trace of being pried, Li Guofu told him that there was a deadbolt in the back door, and before they left last night, the back door had been plugged in, and no one could enter, and he opened it after he came back, and only then did he find his daughter's body. Thinking that it was impossible for Qiu Lanshen to go to the backyard in the middle of the night, her courage was very small, Zheng Wanjiang looked at it and didn't say anything. Upon examination, only one person's fingerprints were found.

"You opened the back door?" Zheng Wanjiang asked. Li Guofu nodded, there is no doubt that this fingerprint is his. Since it was a suicide, Li Qiulan should have gone out through the back door, and it was impossible to plug in the door again, and why there were no fingerprints on the door, this is not a normal phenomenon.

Zheng Wanjiang asked Sun Yaozhang to extract the blood stains on the trunk, he untied the rope, and found that there were also some blood stains on it, which further proved that someone had come to Qiulan's house, who could this person be? On the surface, this person and Qiulan should know each other, because Qiulan has no signs of resistance, but Qiulan must have hanged herself, what is going on? Zheng Wanjiang was a little confused in his heart, and he couldn't solve the mystery in front of him for a while.

"Is this rope your own?" Zheng Wanjiang asked.

"Yes, this rope is indeed our family." Li Guofu replied in the affirmative.

"The rope was put in there? Can you remember? Zheng Wanjiang asked.

"I can't remember this clearly, I have a lot of ropes in my family, and now there is a lot of farm work, maybe it is in Qiulan's house." This is true, it is normal for ropes to be left indiscriminately in farmers' homes.

Zheng Wanjiang carefully inspected the corpse, Li Qiulan's parents had destroyed the scene when they rescued Li Qiulan, and many people came later, and the footprints were disorganized, and there was no longer any value for extraction. He was thinking about how that person was in Qiulan's room, if it was a premeditated murder, then he was undoubtedly the murderer.

Zheng Wanjiang came to the outside of the courtyard wall of the front gate, and found that the courtyard wall was more than two meters high, much lower than the neighbors on both sides, and people with a height of more than one meter eight could easily go up, from the east of the courtyard wall to three meters, he found that there were two mud marks on the wall, which could obviously be seen to be two forefoot shoe prints, he jumped and easily went up the wall, and he went down to the yard.

found two footprints below, he extracted the footprints, and judged that someone had come at night, and the time should be after twelve o'clock at night, because it was less than twelve o'clock at night Li Qiulan's father had called home, and Li Qiulan had not fallen asleep at that time.

But Li Qiulan showed no signs of resistance before she died, and her expression was very peaceful, what the hell is going on? Could it be that it was agreed in advance, but there is no need to come in through the wall, it is completely possible to walk in through the door, why did this person kill her, what means did he use, and this state of death appeared, Zheng Wanjiang shook his head vigorously, trying to make his brain have some ideas, dissect these doubts, but he didn't come up with the reason for a while.

Zheng Wanjiang returned to Li Qiulan's bedroom, wanted to find some clues from it, and told Huang Limei to sample the water cup and water quality in the house, and at the same time extract suspicious fingerprints, he concluded that this person must have entered Li Qiulan's room, Li Qiulan may know this person, otherwise she can't have no signs of resistance, but what is this for?

He saw that Li Qiulan*'s bed sheets had many wrinkles, the average girl was very good and tidy, she should not have fallen asleep before twelve o'clock at night, but why did the bed sheet have many wrinkles, even if he couldn't sleep tossing and turning, a girl's house did not roll out such many wrinkles, he looked carefully, he found that there was a small piece of wet stains on the wall at the head of the bed, it seemed to be saliva, a girl could not have such a bad habit, he looked at the height, and an idea poured into his brain, this should be a man's performance when he was excited, Could it be that it happened with this person before Li Qiulan's death*.

Zheng Wanjiang didn't dare to think about it anymore, if that happened, the case would be even more complicated, what kind of person Li Qiulan is, this is a question to reconsider, especially the huge amount of cash of 108,000 yuan, where did the money come from, who would put this money in Li Qiulan's room for no reason, and this is completely consistent with the amount of deposits that stole He Jinqiang, is this a coincidence? There must be a reason for this. Why did he kill her when he sent her money, and it was unbelievable that this person came prepared.
