Crescent-shaped, with the arc inward or inwardly downward, which is typical of nail wounds.

Lu Xiaozheng frowned and listened, and said in a low voice: "Can you almost be sure that it was mechanical suffocation death?" ”

"Well," Tang Zao said, "It is suspected that he has choked his neck many times." But the intensity is not too great. She frowned and thought for a moment, gently pushed the corpse, and motioned to the assistant to pat the back buckle of the bra: "The hook is wrong, this is a point to pay attention to." ”

Lu Xiaozheng said: "It's likely that someone else helped her wear it?" ”

Tang Zao nodded: "Yes." And most likely a man. She took the swab and sent it for DNA testing as soon as possible, taking a step back: "Let's go back to the autopsy with a body bag." ”

The efficiency of the city bureau has always been very high, or Lu Xiaozheng is very good at using everyone's abilities to the extreme, everyone performs their own duties, basically every time they go back, they can immediately dissect.

Tang Zao used the straight line incision, a steady knife to cut down, the tangent line of the lower jaw midline as the starting point, along the neck, chest and abdomen midline, around the left side of the umbilicus to the upper edge of the pubic symphysis, cut the skin and subcutaneous tissue. After the incision is complete, the soft tissue of the chest is pushed along the ribs from the tangent line to the sides, fully exposing the ribs.

There was no blood accumulation in the thoracic and abdominal cavities, congestion and edema in both lungs, multiple spots and patchy hemorrhages were seen under the costal surface of the two lungs, and there were also multiple spots and patchy hemorrhages on the cardiac septum......

Because it is suspected that it is a mechanical asphyxia death, so the neck examination is particularly important, Tang Zao after the routine neck examination, the knife along the middle of the jaw, pierced into the mouth, along the inner edge of the mandible, cut off the bottom of the mouth to the left and right sides, and pulled the tongue out. This is to check the tip of the tongue, the surface of the tongue, and the upper respiratory tract, and to determine whether the injury is a premortem injury or a postmortem injury by whether the injury is a life reaction.

Since Tang Zao came, Director Chen basically let go, she was the main knife, seeing that her movements were skillful, neat and meticulous, basically he could see the points, she always saw more than him, Director Chen was really satisfied, and after the autopsy was over, he patted her shoulder with rare approval: "Xiao Tang, you are the best forensic doctor I have ever seen, much stronger than when I was young." ”

Tang Zao took off his gloves and smiled: "Thank you for the compliment, I will continue to work hard." ”

It wasn't until the afternoon that Lu Xiaozheng and the others came back, and Tang had already sorted out the autopsy report and held a case analysis discussion meeting in the past.

As usual, the forensic doctor spoke first, and Tang Zao briefly introduced the situation of the corpse, while concluding: "To sum up, the deceased was strangled by others many times, causing mechanical suffocation to death. ”

She paused: "The human body is mechanically suffocated to death due to external force, normally speaking, the whole process from suffocation to death takes about five or six minutes, which is called acute suffocation death." Death that occurs more than four hours after asphyxia is called delayed asphyxia death, and in between, it is called subacute asphyxia death, which is very rare. The deceased in this case was preliminarily judged to have died of subacute asphyxiation. ”

She picked up another report: "The wipes and adhesions on the deceased's body are from the same person, but the pillow towel next to it, as well as the extract of men's slippers, are not the same person." ”

This is a very important clue, Lu Xiaozheng nodded.

Jiang Zhoudao: "There are many shoe prints in the room, which have been investigated, and at present, they are all from the deceased, the informant Zhu Sisi, and a man, the man left leather shoe prints, about four or two yards, which are consistent with the shoe prints left in the suspect's dormitory, and no shoe prints or handprints of the fourth person have been found at present." ”

Yang Man said: "The surveillance at the entrance of the community found that the deceased Qiu Shenghong and the informant Zhu Sisi entered at 10:48 last night and did not go out again. According to Jussi, the deceased's boyfriend, whose stage name is 'Frank', took a taxi back at 11:50 a.m., entered the community, and left at 12:33 a.m., leaving in a panic. She showed everyone the copied surveillance footage.

Zheng Meifei said: "Frank's original name is Zhao Xintao, and he works at Xintiandi KTV, but he didn't find anyone in his dormitory, and his mobile phone couldn't get through. ”

After everyone finished reporting, and at the same time circulated the transcript of the questioning of the informant and neighbors, Zheng Meifei said: "It seems that this Zhao Xintao is very suspicious of committing the crime. ”

Jiang Zhou was the first to support: "I also think so, and according to the reporter's confession, plus the surveillance shows that the reporter and the deceased have not gone out since they entered the community, so there is no possibility of accidental attack, so it can only be this Zhao Xintao." ”

Yang Mei also said: "I agree, Zhao Xintao's roommate confessed that he had dealings with many women, maybe because of this, there was a conflict?" ”

Tang Zao couldn't help but raise his hand, Lu Xiaozheng was raising a hand to speak, and he almost laughed out loud when he was amused by her elementary school student's actions, and said, "Say." ”

Tang Zao also found out that she had brought Jishi's habit over again, so he quickly put it down and said, "I think we should pay more attention to the one who has sex with the deceased. The person who behaves, as I just said, is not too heavy, and it is strangled many times, combined with the deceased's sexual pre-life sex. The circumstances of the behavior, I think, are likely to be accidental death caused by suffocation. ”

"I agree with that." Lu Xiaozheng said calmly: "Even if the autopsy is not considered, when Zhao Xintao entered the community, his mental state was very normal, Zhao Xintao's usual behavior can be identified as an invisible sex worker, he and the deceased have only known each other for a week, the deceased is young, beautiful and rich, much better than his other 'customers', why did he conflict with her and kill her?" This is one. ”

"Second, Tang Zao said before that the deceased did not remove his makeup or change his clothes, that is, he did not take a bath after returning home, but there were wet marks on the toilet paper in the bathroom, that is, someone took a bath before falling asleep, this person could only be Zhao Xintao, and from the panicked state when he fled, it is inferred that the act of taking a bath must have occurred before he found out that the deceased had died, and when he went home, it was close to zero, and the time of death of the deceased was judged to be around eleven o'clock to half past eleven, and it was strangled many times, So he didn't have time to do the crime at all. ”

Tang Zao couldn't help but raise his hand again, reacted halfway, and quickly put it down: "And there is one more point." ”

She flipped through the photos of the corpse and found a corpse's face: "The deceased's makeup is very exquisite, eye shadow, blush, lip gloss, etc., the overall pumpkin color, usually speaking, this kind of makeup is to match the clothes, and her clothes, although the monitoring is too dark to see the color, but it is obviously a T-shirt and denim hot pants." She transferred to the storage basket: "The clothes on it are different from the clothes worn by the deceased at the time, and they are all purple and blue, so I have a bold guess that the deceased's home is not the first scene, and the clothes worn by the deceased that day are still at the first scene." And judging from the state of the corpse, when the deceased was sent home, he was not dead, but was in a coma. ”

"Yes, that's important." Lu Xiaozheng said: "The deceased was sent home, and then put on the bed and covered with a quilt, which explains the state of the quilt and the state of the deceased. ”

Tang Zao said, "So the first scene should not be far from the deceased's home." ”

"It's very likely, it's in the community."

The two of them are a word of you, I am a sentence, with tacit understanding, reasonable, several people were a little convinced, thinking about themselves, Jiang Zhou couldn't help but say: "Then how to explain, there is no fourth person's shoe print in the deceased's house?" How to explain Zhao Xintao's escape? ”
