Xu Tian and Teacher Jin lifted Yi Shuai, who committed suicide on the ground, and under the leadership of Li Zhitong, they crossed two roads in urban villages to the bottom of a house.

This is a two-story single-story building, which looks a bit like a small villa thirty years ago, and this single-story building also has a courtyard, and the courtyard gate is also an iron gate with a sense of age.

Li Zhitong pushed open the courtyard door and beckoned Xu Tian and Teacher Jin to walk in, and the two quickly carried the body into the courtyard gate, and two people wearing white coats with three layers of masks inside and three layers of masks soon came out to take Yi Shuai's body.

"What kind of place is this? Am I guessing wrong? Not a base for undercover cops? Xu Tian asked.

"You did guess wrong, now this place is rented by our criminal investigation team, those two people just now are forensic doctors, they are both from the Dong'an City Police Department, you can rest assured." Li Zhitong said.

"But why is there no one in this place? Is it going to be demolished? Xu Tian asked.

"It will be demolished next month, and because of this, this place will be more private, and it will be more convenient for us to do things here." Li Zhitong said.

"How do I feel like there's something eerie about this?" Xu Tian looked around the courtyard and said.

"It's not just you who feel this way, we discussed it when we first came here to pick a house, there was a homicide in this small single-family building five years ago, and it happened that you came, and we can analyze the case while waiting for the results." Li Zhitong said.

"Haven't you solved the case yet?" Xu Tian asked.

"Because the murderer pointed to by clues and evidence in all aspects committed suicide, so the case has not been closed yet, let me tell you how the murder happened first!" Li Zhitong guided Xu Tian and Teacher Jin to sit on the stone bench in the courtyard. "The original victim was a 10-year-old girl, and on the day of the accident, the little girl secretly fed the puppy outside the courtyard gate with her own dog."

"Secretly feeding?" Xu Tian was very puzzled.

"The cause of the matter has to start from the relationship between the characters of this family, at that time there were only three people living in the family, the little girl's stepmother and her own son lived here with the little girl, because the little girl's biological father died, the little girl had no support, and the family was naturally inherited by the stepmother and younger brother. Since the younger brother is the biological son of the stepmother and father, the stepmother is eligible to inherit the family, so you should be able to guess the status of the little girl in the family, right? Li Zhitong said.

"The stepmother doesn't let the little girl have a dog, and she exploits the dog's food, so the little girl secretly feeds the dog, right?" Xu Tian analyzed.

"That's what it means, but it's still a little bit hot, it's not that simple, and the stepmother's behavior has reached the point of outrageousness. In order to get rid of the puppy that barked at her all day, the stepmother stopped feeding the dog a month before the incident, so the little girl saved her own meals and distributed them to the puppy, and later the stepmother found out that the amount of food given to the little girl at each meal was also halved on the grounds that the little girl couldn't eat so many meals, but the little girl still divided the food in half to the puppy. Li Zhitong said.

"How did the police know about these things? It should be after the incident that the police can intervene in the investigation, right? Can the stepmom tell the police about these things that are not good for her? Xu Tian asked.

"Of course not, the police found a diary in the little girl's room on the second floor, which recorded all the sins committed by that stepmother. At that time, the little girl was secretly feeding the puppy outside the courtyard gate, and a minivan driving in the alley knocked down the little girl, and the case was as simple as that. Li Zhitong said.

"What are the responsibilities of the truck driver?" Xu Tian asked.

"At first, the police did blame the truck driver, but at that time, the owner of a funeral shop at the end of this alley provided evidence to the police, and the shopkeeper provided a video, when the little girl was secretly feeding the puppy outside the courtyard gate, it happened that the truck was coming, and the little girl was holding the puppy to make way for the truck, but when the truck drove very close to the little girl, the camera recording the video suddenly turned the focus away, The whole picture shows the panorama of the little girl, the truck and the single-family building in front of the camera. In the room on the second floor of this single building, the stepmother threw a bun outside the courtyard door, and the little girl saw the bun rolling down, put the puppy under the wall and rushed over to pick up the bun, the truck driver had no time to dodge, and the tragedy happened. Li Zhitong said.

"The stepmother used buns to lure the little girl and caused a car accident, the case is very simple, but the witness has a problem, why was the owner of the funeral shop able to take this video?" Xu Tian asked.

"You don't have to waste your tongue when talking to smart people, the police also found out about this problem, and at the same time as arresting the stepmother, the witness was also questioned, and finally the shopkeeper who testified in the name of the stepmother who admired the little girl, said that the camera hanging on the telephone pole at the door was placed there to secretly photograph the stepmother he loved, although this statement is very far-fetched, but the shopkeeper who testified did not do anything out of the ordinary, and the arrested stepmother also had no intention of pursuing the responsibility of privacy being spied on, so the matter was closed." Li Zhitong said.

"The case isn't over yet, is it?" Xu Tian asked.

"Of course, the arrested stepmother pleaded guilty to her crime at the police station, and her statement was that she did not know that the little girl was outside the courtyard gate, and the truck driver was able to testify at that time, the little girl did squat under the wall with her puppy in her arms, but the little girl squatting under the wall was not visible at all on the second floor, and the stepmother's seduction was not enough to constitute premeditated murder, and finally the stepmother and the driver were convicted of manslaughter and sentenced to two years in prison respectively, with the help of a lawyer, the final sentence was suspended for two years." Li Zhitong said.

"Isn't that? Although the stepmother couldn't see the little girl who was squatting under the wall at the time, the stepmother had a chance to see the little girl walking out with the puppy in her arms, right? And it is certainly not the first time that the little girl has fed the puppy outside the courtyard gate, and an adult has the ability to speculate when and where the little girl fed the puppy, is this sentence a bit light? Xu Tian said.

But the strength of the verdict was well-founded, the truck driver often made deliveries in the alley, and was touched by local residents more than once, so the truck driver placed a miniature camera in the car, after all, dashcams were not yet widespread at that time. At that time, the truck happened to stop at a small restaurant not far away to unload drinks, and it stopped for about ten minutes. In the video evidence provided by the truck driver, the little girl did not squat directly under the wall to feed the puppy after coming out of the house, but walked outside the alley, and after a while walked back with the puppy in her arms, so the judge ruled like that. Li Zhitong said. 10
