The brothers of the Linnan County Criminal Police Team all went back after breakfast, Captain Zhu really entered the role, and divided the labor of the police officers who participated in the war, Deputy Captain Zhou Jie led the technical personnel to further inspect the scene, and the forensic doctor dissected the corpse and determined that Su Laining hosted the murder of the Golden Lotus, and the Sunshine Police Station fully cooperated with the investigation.

After Director Chen learned of the murder, he asked the director for leave and returned to the bureau in advance, and at the same time, Hong Lifei, the captain of the Criminal Police Brigade of the Regional Public Security Department, led the investigators to Jinshui to guide the cracking of the case.

After Director Chen came back, he learned that Captain Zhu was very dissatisfied with the handling of the whole matter last night, and thought that his colleagues in Linnan County should not be allowed to hastily let their colleagues in Linnan County contact Li Jiusheng, who was suspected of committing a major crime, without accurately determining the crime scene and not understanding the motive of the crime, and irresponsibly threw away the so-called traces and physical evidence at the scene.

In addition to Song Xiaojun and Fan Xiaoli, who were rented, Yang Qianfeng and Zhang Lihua took the initiative to find relevant personnel to conduct a comprehensive investigation, and then found Li Jiusheng's two sons, Li Jiusheng's younger brother Li Wansheng and sister-in-law Zhao Xiaoyan and other personnel, as well as all the people and things that Li Jiusheng had contacted and did when he bought cement that day.

Li Jiusheng is the eldest in the family, the following two sisters and a younger brother, the two younger sisters have long been married, their parents died five years ago, his family lives at No. 24 Zhengjia Lane on South Street, which is in the middle of the alley, but their old house is a single-door detached family, half of the old house along the alley has not been demolished, it is still an old house from the alley, but a small half of the old house is demolished, Li Jiusheng used the demolished half and the backyard to make a two-story house with four rooms and two rooms, and the left opposite the house made a kitchen and dining room, On the right are two open-air laundry sinks. On the second floor of the building are the two bedrooms of Li Jiusheng's two sons, the downstairs entrance is a hall, the right is the bedroom of Li Jiusheng and Jin Hehua, and the two rooms on the left are rented to Song Xiaojun and Fan Xiaoli.

And half of the alley that has not been demolished belongs to Li Jiusheng's younger brother Li Wansheng, Li Wansheng is the youngest in the family, married for only a year and has no children, the old house entrance door was originally a lobby room, and now it has become a corridor leading directly to Li Jiusheng's house, there are two rooms on the left, one of which is the bedroom of Li Wansheng and his wife, the other room is to live, usually no one lives, the left half is the kitchen, and there are some firewood and pine leaves that set fire, and the other half is the dining room.

From where Li Jiusheng lives, it is relatively safe, the door of the old house is bolted, if no one inside helps open the door, then no one can enter, and the people inside live are not complicated, a total of eight people, namely: Li Jiusheng, Jin Lotus and two sons, Song Xiaojun and Fan Xiaoli husband and wife, Li Wansheng and Zhao Xiaoyan husband and wife. Now that the Golden Lotus is dead, Li Jiusheng is under control, in fact, there are only six people who are most involved.

Song Xiaojun's reaction during the investigation: The morning before yesterday they were the same as usual, they got up at 6:50 to run and exercise, Jin Lotus had already made breakfast in the kitchen, and Zhu Jiusheng's two sons Zhu Xiaoqing and Zhu Xiaolin were eating in the kitchen after coming back from workout, Jin Lotus soaked clothes with laundry detergent by the pool, and did not see Zhu Jiusheng, after returning home, the two of them brushed their teeth and washed their faces, and went to work together after brushing their teeth and washing their faces, and went to work after eating breakfast, and ate at Fan Xiaoli's parents' house at noon, and went to the rented house to take a nap for about an hour after lunch. At night, I usually have dinner and play for a while, play until about nine o'clock to go home to sleep, the day before yesterday after lunch and go back to take a nap, but from going back to taking a nap to get up to work, I haven't seen the golden lotus, there are still a few pieces of clothes in the pool that have not been washed, the washed clothes are dried, and I haven't seen Zhu Jiusheng and their son and Zhu Wansheng and his wife, the whole yard is quiet. I came back late the night before yesterday, it was more than ten o'clock, the lights in the room of Li Jiusheng's two sons were on, and the yard was still quiet, and I always felt that something was missing, Fan Xiaoli said that the puppy didn't bark at night, and suddenly remembered that I hadn't seen the dog for a day, and I didn't hear its barking. When I woke up the next morning, I found Li Jiusheng sitting alone in the yard smoking, I asked him why it was so early, and he said that his wife was gone, and I heard that he was not still doing laundry yesterday morning. It seems that the clothes have not been washed and something has happened, did they not go to work? Li Jiusheng lowered his head and said that her unit was found and she didn't go to work, all her relatives, friends and good colleagues were searched, she didn't go to their house, why did she disappear well?

I asked if I was going out to play, and he said it couldn't be, even if I went out to play, I would say hello, and I had never said anything like this. I advised him not to rush, he was sure he would be fine, and he might be back later.

Yang Qianfeng asked Song Xiaojun: Have there been any conflicts and quarrels in their family?

Song Xiaojun said with certainty: Anyway, he and Fan Xiaoli didn't have it when they were there.

When Song Xiaojun and Fan Xiaoli learned from Zhang Lihua that the golden lotus was killed, they were very surprised, and Song Xiaojun said: How can this be? She was still doing the laundry the day before yesterday. Fan Xiaoli said: That's right! Her black pet dog was still sleeping at her feet while she was doing the laundry! After speaking, Fan Xiaoli slapped his face and said: No wonder I didn't see the dog, did she take the dog out to play and had an accident.

Then Yang Qianfeng learned from them about the dog's situation and Li Jiusheng's personality, living habits, and the means of transportation he usually used to go out.

During the investigation, Zhu Wansheng and his wife reacted: they usually don't cook much at home, they eat at his mother-in-law's house at noon, rest there after eating, go to work when they go to work, watch TV there after eating at night, and go home to sleep until nine to ten o'clock, and go back to bed at almost ten o'clock the night before yesterday, and no abnormalities were found! It was only when he heard his eldest brother talking to Song Xiaojun in the courtyard the next morning that he learned that his sister-in-law had disappeared the day before, so he specially asked for leave to help his eldest brother go to relatives and friends' houses to find her, but they all said that they didn't see her.

Then Yang Qianfeng asked Jin Lotus about the conflict with those people, how his relationship was with his eldest brother, whether he had an extramarital affair and so on. When they heard that Jin Lotus was killed, the two of them didn't believe it at all, and excitedly said that it was impossible for someone to harm their sister......-in-law, and when they calmed down, they also helped Yang Qianfeng and Zhang Lihua analyze the matter, but they didn't suspect Li Jiusheng, of course, they didn't know that the scene of Jin Lotus's final murder was in the attic of their sleeping room.

During the investigation, it was found that Li Jiusheng's two sons were also strange about their mother's disappearance, and their mother was fine when they ate and went to school that morning, and when they came back at noon, they didn't see her thinking that they were working overtime in the unit, so they went to their aunt's house to eat, because the golden lotus had told them that as long as she came back from school at noon, she would go to her aunt's house to eat before she got off work, but she didn't come back in the evening, and they went to her aunt's house for dinner, and they didn't see their mother when they came back from self-study at night, thinking that something had happened with their father. It was not until the next morning that they heard from their father that their mother was not with him, and that their mother was missing, and they were shocked and said that they were going to look for their mother, but their father told them to go to school and find their mother's business.

Then Yang Qianfeng asked about their family separately. But Yang Qianfeng didn't tell them about their mother's murder.

After investigating these people, Yang Qianfeng and Zhang Lihua asked Zhu Jiusheng's two sisters-in-law, Jin Hehua's colleagues and friends, and neighbors and others to get to know each other, and had a comprehensive understanding of the activities on the day of the incident that Li Jiusheng told at the police station.

Yang Qianfeng said to Zhang Lihua: It is certain that people will die in the attic, if the first thought of the people outside is to leave the scene as soon as possible, and there is no need to take such a big risk to turn around and transport the body from there to the river to throw it into the river, and the body can not be transported to the river during the day, only at night, not that the people who live there can't enter at night.

Zhang Lihua said with the same feeling: That's right, it must be the people who live inside who committed the crime, and it is impossible for outsiders to move the body again, let alone throw the body. According to what we learned from our visit, Li Jiusheng should be the No. 1 suspect, but there is no No. 2 suspect except him.

Yang Qianfeng nodded and said: Then when did he commit the crime?

Zhang Lihua said: After the autopsy, everything was clear.

Yang Qianfeng pointed in the direction of the Jinshui River and said: Let's do an experiment to see how much time it takes for the three roads from Li Jiusheng's house to the Jinshui River, and then see which road is the most hidden.

Zhang Lihua made a gesture of please, and said with a smile: This idea is good, please!
