"There is no time to commit the crime."

"No, she really didn't." The team member put down his hand: "Deputy team, you don't know how miserable she is, you have to know how miserable she is, you can understand why she hates Zhu Lili so much, why she posted on the Internet, and why she supported that Wang Kai to pit Zhu Lili." ”

"Why?" Deputy Captain Tan asked.

"Because Julie ruined her home, ruined her life. Of course, the main reason for this is still in that Zhao Yang, because he didn't control himself, because he didn't take his wife and children and his family seriously. But the deputy team, this Nansheng is really not easy. What about this Zhao Yang, although his work ability is good, he changes jobs every now and then, so that he has worked for more than ten years, and he has no savings. It's just that he doesn't have savings, and he's still in debt. Even if he is in debt, he also has a relationship with Julie about men and women. ”

"Getting to the point."

"The point is that after he got along with Julie, he didn't care about the affairs of the family, which required no one and no money. At that time, Nan Sheng had just given birth to her second child, and she had to take care of her youngest son who was waiting to be fed, and she also had to take care of the big study at home. On top of that, you have to worry about making money. The three of them have to eat, drink, and wear. Not to mention going out to commit murder, she didn't even have time to sleep. ”

The team member sighed: "When we went to investigate, as soon as we mentioned Nan Sheng's physical characteristics, many people around took the initiative to come up and talk about it. It's not easy to say that this Nan Sheng, saying that her little son is very noisy, when he was young, he often saw Nan Sheng holding the child downstairs before dawn. At noon, everyone else was eating at home, and she was still holding the child downstairs. Do you think she'll be able to rest at night? No, this person who lives in the same building, whether you get off work at 6 o'clock, 8 o'clock, or 1 o'clock in the morning, you have met her downstairs. Vice, do you think this is a human life? ”

"It's bitter." Deputy Captain Tan frowned: "Your sister-in-law was also very miserable at that time, but fortunately, there are old people at home to help me, if there is no old man, I don't know how to live that day." By the way, doesn't this Nansheng have the help of an old man? ”

"I heard from the neighbors that her mother lived with her for a while, and then because her brother and daughter-in-law were going to have a baby, her mother left. Since then, she has been taking care of two children by herself. The team member said: "We specially asked about the time before and after Wang Kai's accident, and they said that Nansheng was still the same as before, nothing special." She takes her eldest son to school in the morning and then takes her younger son during the day. At four o'clock in the afternoon, I went to pick up my eldest son from school. The next-door neighbor also reported that her family was full of people from morning to night, and she heard Nan Sheng talking to her youngest son from time to time. Listening to the voice, she was often so angry with her naughty little son that she lost control of her emotions. ”

"Have you seen the elevator monitoring?"

"I saw it, and the reaction of the neighbors was basically the same. Because of the child, Nansheng took the elevator up and down the stairs, and the time basically coincided. Judging from the evidence we currently have, Nan Sheng has no direct relationship with Wang Kai's death, and the information she told the deputy team is basically true. ”

"Got it, go check Tong Yue."

"Well, I'll go now, I hope this Tong Yue, like Nan Sheng, belongs to the category that is particularly easy to check."

As soon as the team left, the forensic doctor called about the cause of death of Wang Kai and Song Qingwei.

Wang Kai and Song Qingwei both died of murder, but the causes of death were slightly different.

No obvious struggle injuries were found on Wang Kai's body, and the cause of death was a ruptured heart. According to the autopsy results, it is very likely that the murderer used a soft object such as a pillow or cushion to cushion the deceased's heart after Wang Kai's head injury caused him to fall into a coma, and then caused a heart rupture through a violent impact. It cannot be ruled out that the murderer used something other than his knee, such as a small hammer, or something similar to a small hammer. This murder weapon will not be taken out by the murderer, it is very likely to be something from Wang Kai's house, and the scene needs to be reviewed.

The cause of Song Qingwei's death was relatively simple, that is, simple excessive blood loss. In addition to the wound caused by the ashtray visible on the head, a fatal wound was found on the cervical vertebrae of the deceased, who had been pierced by steel nails.

It is said to be a steel nail, but it is actually more similar in shape to a 2B pencil, but it is only two-thirds the length of a pencil. This steel nail was nailed to Song Qingwei's neck and almost all of it was buried, because there was blood on the face and neck of the deceased, and the scene where the corpse was rotten, so when he was at the scene, no one noticed this part of the deceased.

The reason why the deceased's neck was not pierced was because the steel nails were nailed to Song Qingwei's cervical vertebrae.

"Cervical?" Deputy Captain Tan gestured with his hand: "If you want to nail this thing into the cervical spine of the deceased, do you have to have an auxiliary tool?" ”

"You can't do it with manpower alone." The medical examiner said: "But I can't say what kind of auxiliary tool it is." ”

"You're a medical examiner!"

"I'm a forensic doctor, not a god, I'll give you some reference ideas at most."

"What's that idea?"

"Not yet, you'll have to make me think about it."

Without waiting for Deputy Captain Tan to speak, the forensic doctor hung up the phone directly.

Thinking that Song Qingwei's cervical vertebrae were pierced by steel nails, Vice Captain Tan felt a chill in his back, and couldn't help touching his neck with his hand.

The steel nail is nothing else, and it is almost impossible to pierce it directly into the opponent's cervical vertebrae with your hand. But what tools does the murderer have access to?

Before Deputy Captain Tan could figure out the matter of the auxiliary tools, there was new news from the personnel in charge of on-site exploration. During a secondary survey of the site, they discovered something. The computers of the deceased Wang Kai and the deceased Song Qingwei were all touched, especially Song Qingwei's computer.

"What's missing?" Vice Captain Tan pressed his temples with his hands.

"The hard drive, the hard drive in the computer is gone." The other party said: "It's not that it's gone, but it's been replaced." ”

"Changed one?!" Vice Captain Tan opened his eyes: "What do you mean by changing one?" ”

"It's just that someone removed the hard disk in Song Qingwei's computer and installed a new hard disk, and this hard disk is still second-hand."

"How do you know it's second-hand? Even if it is second-hand, it may be that Song Qingwei himself bought it from the second-hand market. ”

"We contacted Song Qingwei's wife, Tong Yue, and according to Tong Yue, the computer was configured three years ago. Because Song Qingwei himself is not very knowledgeable about computers, when they bought a computer, they specially invited a friend to come over to be a staff officer for them. All the configurations in the computer are new, and it costs nearly 10,000 yuan to complete the set, and Song Qingwei's main purpose with this computer is to play games and watch movies. ”

"Tong Yue seems to have mentioned playing games."

"Yes, we did find the installed and uninstalled games in the computer, but this game is not the same as the game that Song Qingwei often plays, and there is no trace of this uninstalled game. To put it bluntly, it is to leave similar traces and fool people. ”
